Now, at least some, users have received their long awaited Tablets (me being one of the lucky few =). I have just given it a short test run so far but it seems handle all tasks I need it for.

However, there is one thing I have not figured out yet. That's the support for microSD cards. I know there was some discussions/polls regarding this a year ago but do not know what it resulted in.

Before ordering some new SD-cards for it I think it would be good to have a bit better understanding about its capabilities. Things that would be great if it worked is: Support for 128GB SDXC cards and a file system capable of handling files greater than 4GB.

Anyone having better knowledge than me regarding this? Maybe we could collect some useful guides and links to third part solutions here.

SDXC support was paid for by tablet supporters but later ditched by Jolla for financial reasons. You could try to re-format SDXC cards to supported file systems. However, you will lose your data, probably lose conpatibility to other devices - and, above all, will lose performance, reliability and speed if you don't put a lot of effort into aligning the logical blocks of the file system to the physical ones of the card.

In short: Don't buy and use such cards.

128 GB SDXC card formated to Ext4 without journaling works well in Jolla-Tablet! Since I'm only using Linux it's just perfect combination to synch data from PC to Jolla Tablet! I'm using this since about 1 month & I'm very satisfied!!!

As mentioned above it's possible to use such large SD-cards, but be aware of a few things to be considered and some work/time you need to spend! Ext4 and BTRFS file formats are possible to handle from Jolla-Tablet. I recommend to download FILECASE with root-rights or FILETUG from Warehouse so you can check if the card is read right on the J-Tablet. Please consider also: https://jolla.zendesk.com/hc/en-us/articles/201997993-What-kind-of-SD-cards-and-formats-are-supported AND you would need to tweak/opimize the Ext4-formated card: https://jolla.zendesk.com/hc/en-us/articles/201997993-What-kind-of-SD-cards-and-formats-are-supported

As I said it's possible! Otherwise this is a duplicate...

Elevated you to answer and yes this is a duplicate, answered so many times I cannot even count it. Jolla's devices are both the same, limitations come from the named standards. Jolla1 supports cards bigger than SDHC just no exfat and so does Jolla-Tablet. SDHC and SDXC are stupid names for sizes with specific formatting. You can put close to any Linux supported FS onto your card with no (big) hassle - out-of-the-box you may just use one of the common extX or btrfs and yes 128GB flash-cards do work (depending on brand maybe but in general they do work)

closing as duplicate

Just found a couple of sd-cards and a bit of spare time to do some testing. Formatted the cards to Ext2 and, as expected, it works well on both Tablet and Linux PC.

Read/write access from a Windows PC (running Win7 64-bit) was a bit more trouble. Tested some different solutions and found that the the program Ext2 IFS for Windows worked well enough, at least for my needs. Got the program to stop responding on some occasions but normally no problem to both read and write from the cards. Also files over 4GB worked fine.

As I only had access to 32GB and 64GB cards, I still do not know if 128 GB works but from the comments here I am not that worried.
