Since the info about microSD card related info is all over the place I though it would be good to have all the info in one wiki post.

There are 3 types of microSD cards and Jolla should support all three formats: microSD - from 64 MB to 2 GB microSDHC - sizes between 4 GB to 64 GB microSDXC - up to 128GB

  • Jolla supports up to 64GB MicroSDHC cards is size. (strange that there is no mention of it on their website)

  • There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu as per post over here.

  • Windows Users: as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size

  • Reformatting micro SD card inside phone settings as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here. [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1

Since the info about µSD card related info is all over the place I though it would be good to have all the info in one wiki post.

There are 3 types of µSD cards and Jolla should support all three formats:
microSD - from 64 MB to 2 GB
microSDHC - sizes between 4 GB to 32 GB
microSDXC - up to 128GB

Price:
Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
Up to 70 MB/s Read and up to 20 MB/s Write
£42.99 18-Mar-14
EUR 45,89 18-Mar-14

SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
Up to 30MB/s read speed; write speed lower.
£33.20 18-Mar-14
EUR 45,99 18-Mar-14

Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

What should good quality µSD card have when buying new one?
- UHS-I
- Class 10

  • Jolla supports up to 64GB µSD cards is size. (strange that there is no mention of it on their website)

  • There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.

  • Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit

  • Reformatting micro SD card inside phone settingssettings - EXT4
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1

  • Formating the card as BTRFS as found in Answer to this question.
    [root@localhost nemo]# mkfs.btrfs /dev/mmcblk1p1



  • - Usefull commands from the developer mode:

    program for creation and manipulation of partition tables
    [root@localhost nemo]# fdisk -l

    df displays the amount of disk space available on the file system / µSD card

    Wiki: microSD / microSDHC / microSDXC card

    Since the info about µSD card related info is all over the place I though it would be good to have all the info in one wiki post.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s Read and up to 20 MB/s Write
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10

    • Jolla supports up to 64GB µSD cards is size. (strange that there is no mention of it on their website)

    • There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
      as per post over here.

    • Windows Users:
      as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit

    • Reformatting micro SD card inside phone settings - EXT4
      as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
      [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1

    • Formating the card as BTRFS as found in Answer to this question.
      [root@localhost nemo]# mkfs.btrfs /dev/mmcblk1p1

    • Mapping your Jolla µSD card on your Linux PC using Secure SHell FileSystem (works on Debian Wheezy)
      sudo apt-get install sshfs to install Secure SHell FileSystem if not already installed
      sudo usermod -aG fuse marcel to add user marcel to fuse group
      exec su -l $USER to restart your login
      mkdir jolla make a folder where the µSD will be mapped
      sshfs -p 22 nemo@192.168.1.26:/run/user/100000/media/sdcard ~/jolla -o follow_symlinks to moount the µSD card

      -p 22 - is the SSH port of your Jolla
      nemo@192.168.1.26 - is your Jollas default user / local IP address
      /run/user/100000/media/sdcard - is where Jollas µSD card is mounted to
      ~/jolla - is folder your Jollas µSD will be mounted to
      -o follow_symlinks - is a command to follow symlinks on the µSD card

      fusermount -u ~/jolla to unmount µSD card from your PC



    - Usefull commands from the developer mode:

    Wiki: microSD / microSDHC / microSDXC card

    Since the info posts about µSD card related info is all over the place I though it would be good to have it all the info in one wiki post.post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s Read and up to 20 MB/s Write
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10


    - Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    - There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    - Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    - Reformatting micro SD card inside phone settings - EXT4
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1

    - Mapping your Jolla µSD card on your Linux PC using Secure SHell FileSystem (works on Debian Wheezy)
    sudo apt-get install sshfs to install Secure SHell FileSystem if not already installed
    sudo usermod -aG fuse marcel to add user marcel to fuse group
    exec su -l $USER to restart your login
    mkdir jolla make a folder where the µSD will be mapped
    sshfs -p 22 nemo@192.168.1.26:/run/user/100000/media/sdcard ~/jolla -o follow_symlinks to mount the µSD card

    -p 22 - is the SSH port of your Jolla
    nemo@192.168.1.26 - is your Jollas default user / local IP address
    /run/user/100000/media/sdcard - is where Jollas µSD card is mounted to

    -o follow_symlinks - is a command to follow symlinks on the µSD card

    fusermount -u ~/jolla to unmount µSD card from your PC

    - How user can take backups out of device post over here

    check that the µSD card is mounted [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    to check what is the size of the backup folder [nemo@localhost ~]$ du ?????


    create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s Read and up to 20 MB/s Write
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10


    - -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    - -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu

    -- Windows Users:

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s Read and up to 20 MB/s Write
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1
    you may have to manually mount the µSD or use script (1.0.3.8 Naamankajärvi)

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s Read and up to 20 MB/s Write
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s Read read speed; and up to 20 MB/s Writewrite speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1
    you may have to manually mount the µSD or use script (1.0.3.8 Naamankajärvi)


    -- Formating the card as BTRFS as found in Answer to this question.
    [root@localhost nemo]# mkfs.btrfs /dev/mmcblk1p1
    you may have to manually mount the µSD or use script (1.0.3.8 Naamankajärvi)


    -- Mapping your Jolla µSD card on your Linux PC using Secure SHell FileSystem (works on Debian Wheezy)
    sudo apt-get install sshfs to install Secure SHell FileSystem if not already installed
    sudo usermod -aG fuse marcel to add user marcel to fuse group
    exec su -l $USER to restart your login
    mkdir jolla make a folder where the µSD will be mapped
    sshfs -p 22 nemo@192.168.1.26:/run/user/100000/media/sdcard ~/jolla -o follow_symlinks to mount the µSD card

    -p 22 - is the SSH port of your Jolla
    nemo@192.168.1.26 - is your Jollas default user / local IP address
    /run/user/100000/media/sdcard - is where Jollas µSD card is mounted to (1.0.3.8 Naamankajärvi)
    /media/sdcard/xxxx-xxxx - is where Jollas µSD card is mounted to (1.0.4.20, Ohijärvi)
    ~/jolla - is folder your Jollas µSD will be mounted to on you PC
    -o follow_symlinks - is a command to follow symlinks on the µSD card

    fusermount -u ~/jolla to unmount µSD card from your PC

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1 - format the card
    [root@localhost nemo]# chmod -R 777 /run/user/100000/media/sdcard/ - set permissions
    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script script (1.0.3.8 Naamankajärvi)


    -- Formating the card as BTRFS as found in Answer to this question.
    [root@localhost nemo]# mkfs.btrfs /dev/mmcblk1p1
    you may have to manually mount the µSD card or use script script (1.0.3.8 Naamankajärvi)

    sshfs -p 22 nemo@192.168.1.26:/run/user/100000/media/sdcard ~/jolla -o follow_symlinks to mount the µSD card

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.

    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.

    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)
    


    - and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault


    - to check that the BackUp has been created:
    [nemo@localhost sdcard]$ ls -ila /run/user/100000/media/sdcard/vault*

    13194 -rwxr-xr-x 1 nemo nemo 1544919040 2014-03-19 11:44 /run/user/100000/media/sdcard/vault.tar

    Wiki: microSD / microSDHC / microSDXC card

    Since the posts about µSD card related info is are all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)
    


    - and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault


    - to check that the BackUp has been created:

    Wiki: microSD / microSDHC / microSDXC card

    [INFO] 1.0.4.20: directory change

    1.0.4.20 - New location: /media/sdcard/xxxx-xxxx 1.0.3.8 - Old location: /run/user/100000/media/sdcard

    Since the posts about µSD card related info are all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT, so use Linux PC or see below how to get the card working from the phone over ssh


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card

    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)


    -- Formating the card as BTRFS as found in Answer to this question / via SSH.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.btrfs -f /dev/mmcblk1 - format the card (no need for partition)

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)

    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault

    Wiki: microSD / microSDHC / microSDXC card

    [INFO] 1.0.4.20: directory change

    1.0.4.20 - New location: /media/sdcard/xxxx-xxxx
    1.0.3.8 - Old location: /run/user/100000/media/sdcard

    Since the posts about µSD card related info are all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT, so use Linux PC or see below how to get the card working from the phone over ssh


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1 - format the card
    [root@localhost nemo]# chmod -R 777 /run/user/100000/media/sdcard/ - set permissions
    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)


    -- Formating the card as BTRFS as found in Answer to this question / via SSH.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.btrfs -f /dev/mmcblk1 - format the card (no need for partition)
    [root@localhost nemo]# mount -o subvolid=0 /dev/mmcblk1 /media/sdcard - mount the card
    [root@localhost sdcard]# btrfs subvolume create Jolla - create folder called Jolla
    [root@localhost sdcard]# chown -R nemo:nemo /run/user/100000/media/sdcard/Jolla - set ownership
    [root@localhost sdcard]# chmod -R 775 /run/user/100000/media/sdcard/Jolla - set permissions
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)


    -- Mapping your Jolla µSD card on your Linux PC using Secure SHell FileSystem (works on Debian Wheezy)
    sudo apt-get install sshfs to install Secure SHell FileSystem if not already installed
    sudo usermod -aG fuse marcel to add user marcel to fuse group
    exec su -l $USER to restart your login
    mkdir jolla make a folder where the µSD will be mapped
    sshfs -p 22 nemo@192.168.1.26:/run/user/100000/media/sdcard ~/jolla -o follow_symlinks to mount the µSD card

    -p 22 - is the SSH port of your Jolla
    nemo@192.168.1.26 - is your Jollas default user / local IP address
    /run/user/100000/media/sdcard - is where Jollas µSD card is mounted to (1.0.3.8 Naamankajärvi)
    /media/sdcard/xxxx-xxxx - is where Jollas µSD card is mounted to (1.0.4.20, Ohijärvi)
    ~/jolla - is folder your Jollas µSD will be mounted to on you PC
    -o follow_symlinks - is a command to follow symlinks on the µSD card

    fusermount -u ~/jolla to unmount µSD card from your PC

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT, so use Linux PC or see below how to get the card working from the phone over ssh


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card

    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)


    -- Formating the card as BTRFS as found in Answer to this question / via SSH.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)
    


    - and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault


    - to check that the BackUp has been created:
    [nemo@localhost sdcard]$ ls -ila /run/user/100000/media/sdcard/vault*

    13194 -rwxr-xr-x 1 nemo nemo 1544919040 2014-03-19 11:44 /run/user/100000/media/sdcard/vault.tar

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)
    


    - and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault


    - to check that the BackUp has been created:

    Wiki: microSD / microSDHC / microSDXC card

    [INFO] 1.0.4.20: directory change

    1.0.4.20 - New location: /media/sdcard/xxxx-xxxx
    1.0.3.8 - Old location: /run/user/100000/media/sdcard

    Please vote for better integration of the SDcard into the OS core apps here!

    Since the posts about µSD card related info are all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:
    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-I
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not (as of 1.0.3.8 Naamankajärvi) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT, so use Linux PC or see below how to get the card working from the phone over ssh


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1 - format the card
    [root@localhost nemo]# chmod -R 777 /run/user/100000/media/sdcard/ - set permissions
    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)


    -- Formating the card as BTRFS as found in Answer to this question / via SSH.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.btrfs -f /dev/mmcblk1 - format the card (no need for partition)
    [root@localhost nemo]# mount -o subvolid=0 /dev/mmcblk1 /media/sdcard - mount the card

    How to check if you card is fake/counterfeit?
    Windows: - h2testw
    Linux: - F3 (Fight Flash Fraud)
    When doing such a test, never interrupt/cancel the test as that may result in you µSDxx being corrupt.

    or simply try to fill up to the card with movies/ISO files to see if the card has claimed capacity.

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)
    


    - and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault


    - to check that the BackUp has been created:
    [nemo@localhost sdcard]$ ls -ila /run/user/100000/media/sdcard/vault*

    13194 -rwxr-xr-x 1 nemo nemo 1544919040 2014-03-19 11:44 /run/user/100000/media/sdcard/vault.tar
    




    ToDo:
    - copying files to µSD card over cable
    -

    Wiki: microSD / microSDHC / microSDXC card

    [INFO] 1.0.4.20: directory change

    1.0.4.20 - New location: /media/sdcard/xxxx-xxxx
    1.0.3.8 - Old location: /run/user/100000/media/sdcard

    Please vote for better integration of the SDcard into the OS core apps here!

    Since the posts about µSD card related info are all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:

    Be aware that there is loots of "fake/counterfeit" cards being sold on eBay/Amazon. Only buy from reputable sources.

    How to check if you card is (not) fake/counterfeit?
    Windows: - h2testw
    Linux: - F3 (Fight Flash Fraud)
    or simply try to fill up to the card with movies/ISO files to see if the card has claimed capacity.

    When doing such a test, never interrupt/cancel the test as that may result in you µSDxx being corrupt.

    or simply try to fill up to the card with movies/ISO files to see if the card has claimed capacity.

    Samsung microSDXC 64GB Class 10 UHS-1 Grade 1
    Up to 70 MB/s read speed; and up to 20 MB/s write speed
    £42.99 18-Mar-14
    EUR 45,89 18-Mar-14

    SanDisk Ultra microSDXC 64GB Class 10 Bi-coloured Card with Adapter
    Up to 30MB/s read speed; write speed lower.
    £33.20 18-Mar-14
    EUR 45,99 18-Mar-14

    SanDisk Extreme PLUS microSDHC/microSDXC UHS-I Card - SDSDQX-064G
    Up to 80MB/s read speed; and up to 50MB/s write speed

    Cards that have fast write/read speeds like UHS-I [UHS-I](http://www.integralmemory.com/faq/what-uhs-1) are better as they will not slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-1 or even better UHS-3
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is not "NOT" (as of 1.0.3.8 Naamankajärvi) 22.12.2014 - 1.1.1.27 Vaarainjärvi ) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT, so use Linux PC or see below how to get the card working from the phone over ssh


    -- Windows Users:
    as per post over here, NTFS NTFS and exFAT exFAT formats are not supported supported, but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limitlimit.

    SD Formatter 4.0 for SD/SDHC/SDXC The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards.


    -- Reformatting micro SD card inside phone settings - EXT4 / via SSH
    as per post over here, you can format the µSD from the developer mode, as root Howto log in / access dev mode over here.
    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.ext4 /dev/mmcblk1p1 - format the card
    [root@localhost nemo]# chmod -R 777 /run/user/100000/media/sdcard/ - set permissions
    [root@localhost nemo]# mount -t ext4 /dev/mmcblk1p1 /run/user/100000/media/sdcard/
    you may have to manually mount the µSD card or use script (1.0.3.8 Naamankajärvi)

    [root@localhost nemo]# umount /dev/mmcblk1p1 - unmount the card
    [root@localhost nemo]# mkfs.btrfs -f /dev/mmcblk1 - format the card (no need for partition)

    Please vote for better integration of the SDcard into the OS core apps here!

    Since the posts about µSD card related info are all over the place I though it would be good to have it all in one wiki post. Please feel free to edit/amend.

    There are as of 2014 3 types of µSD cards and Jolla should support all three formats:
    microSD - from 64 MB to 2 GB
    microSDHC - sizes between 4 GB to 32 GB
    microSDXC - up to 128GB

    Price:Prices:
    Be aware that there is loots of "fake/counterfeit" cards being sold on eBay/Amazon. Only buy from reputable sources.

    How to check if you card is (not) fake/counterfeit?
    Windows: - h2testw
    Linux: - F3 (Fight Flash Fraud)
    or simply try to fill up to the card with movies/ISO files to see if the card has claimed capacity.
    When doing such a test, never interrupt/cancel the test as that may result in you µSDxx being corrupt.

    Cards that have fast write/read speeds like [UHS-I]UHS-I(http://www.integralmemory.com/faq/what-uhs-1) are better as they will not "not" slow down your phone, when it writes / reads from / to the card. I am assuming that Jolla is UHS-I compatible.

    What should good quality µSD card have when buying new one?
    - UHS-1 or even better UHS-3
    - Class 10
    - Fast Read / and most important Write speed


    -- Jolla supports up to 64GB µSD cards in size. (strange that there is no mention of it on their website)


    -- There is "NOT" (as of 22.12.2014 - 1.1.1.27 Vaarainjärvi ) support for the µSD indicator in the phones menu
    as per post over here.


    -- NEW CARDS:
    - if you have brand new µSD card that you have purchased for the Jolla, most if not all of them come pre formatted to be able to use them straight away and compatible with Windows OS (so their file system is FAT16 / FAT32 aka vfat), so if you have card that is not bigger that 32Gb that will work out of box).
    - according to post on xda-developers, 64Gb cards come formatted as exFAT, so use Linux PC or see below how to get the card working from the phone over ssh


    -- Windows Users:
    as per post over here, NTFS and exFAT formats are not supported, but FAT32 (vfat) is, but it has got limit of 4GB per file in size and single partition with 32 Gb size limit.

    -- How user can take backups out of device to SD post over here, creating tar file

    • to create back up on your Jolla -> Settings -> Backup (pick what you want to backup - Accounts, Browser, Gallery, Playlists, Messaging, People, Phone) -> Create
    • Backup files are located in Jolla memory in /home/nemo/.vault hidden folder


    - check that the µSD card is mounted
    [nemo@localhost ~]$ mount | grep media

    /dev/mmcblk1p1 on /run/user/100000/media/sdcard type vfat (rw,relatime,uid=100000,gid=100000,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
    


    /dev/mmcblk1 on /run/user/100000/media/sdcard type btrfs (rw,relatime,thread_pool=4,ssd,noacl,space_cache)
    


    - and that BackUp has been created on your Jolla
    [nemo@localhost ~]$ ls -ald ~/.vault

    drwxr-xr-x 1 nemo privileged 144 2014-03-18 09:42 /home/nemo/.vault
    


    - to check what is the size of the backup folder
    [nemo@localhost ~]$ du ?????


    - create a BackUp file "vault.tar" to your µSD card (I think it could be a good practise to date the file vault_20140319.tar):
    [nemo@localhost ~]$ tar cf $XDG_RUNTIME_DIR/media/sdcard/vault.tar -C $HOME .vault


    - to check that the BackUp has been created:
    [nemo@localhost sdcard]$ ls -ila /run/user/100000/media/sdcard/vault*

    13194 -rwxr-xr-x 1 nemo nemo 1544919040 2014-03-19 11:44 /run/user/100000/media/sdcard/vault.tar
    




    ToDo:
    - copying files to µSD card over cable
    -
