What file systems can I use with my SD card on a Samsung A10S?



  • I'm using a Samsung A10S phone. I use Arch Linux, no Windows, and I want my phone's SD card to be highly compatible with my PC. The default SD format seems to be vFAT which disallows many special characters in file names that are no problem on a Linux machine (:, *, ?, "). I've tried formatting the SD card with EXT4 & EXT3 but when I put it back into the phone, it seems to be unable to work with the card and made me format it. There was no option as to what file system would be used and the card is now vFAT. I've tried looking online for possible file systems to use with the A10S but to no avail.

    What file systems are compatible with the Samsung A10S? If there are others besides vFAT, what would be best for working with a Linux system?

    Edit: 1 big reason I wanted ext4 instead of vFAT is because I wanna get rid of the problem of certain disallowed special characters in vFAT so I'd like something without those restrictions.



  • I would second what @alecxs said, go for exFAT filesystem, that one will be compatible with all the OSes involved.
