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

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.

- Usefull commands from the developer mode:

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

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 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

- 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:
