Is my understanding correct that microSD cards up to 32 GB are supported by default? E.g. I can use them in a camera, PC, Mac, Linux without formatting/doing anything?

MicroSD cards up to 32GB (also known as SDHC) formatted as FAT32 are supported.

All of the recent exFAT discussion on TJC concerns only SDXC cards, which are larger than 32GB.

That is correct. I would just like to add that I am currently using a factory formatted 16GB card with no problems whatsoever.

IIRC 64GB can also be formatted with FAT32 or vFAT - there is just that 4GB filesize limit... that SDXC standard just says that cards come pre-formatted with exFAT and a device reading SDXC can handle exFAT - nothing more, FAT32 limit is 4GB filesize and 16TiB FS size (4KB), FAT32+ could have 265GB filesize but that is not so widely used. I think my 64GB pendrive came FAT32 formatted, can't tell anymore as it is xfs now...

You're OK with FAT32 formatted SDXC cards in a Jolla and also Windows, Linux and Mac. Apart from the file size limit you may also hit problems with filenames where some filesystem's allow more characters and may also be case sensitive.

However, some devices will not read SDXC cards formatted with anything other than ExFAT so it's best to test your devices with a FAT32 formatted SDXC card before you put data on them or rely on FAT32 as a common denominator.
