After the latest system update on my S20, none of the files are not readable on my encrypted SD card. It is odd since the File structure is still accessible (perhaps wasn't encrypted) but the actual files cannot be opened. Any insight into issue? Would rolling back the update (if even possible) allow me to recover the files? Actually, almost all are backed up but photos from a concert had not been backed up yet. In any event, this is an annoying inconvenience.
Also, Samsung rep told me the card was corrupted due to the 'symptoms' of seeing the file structure, but not being able to open the files. After running a test on my old S8, this just seems to be how the encrypted files appear when trying to open on a different device. It's really like the phone simply no longer recognizes it's own encryption. Samsung needs to get this fixed.
I wish I had something more useful to add than "me too", but, me too. After software update 16 Sept, the phone won't read original encrypted sd card files (ok, I've got backups, so I'll replace card). Now I can't get new card encrypted, it just says "Checking SD card" forever
Can you confirm if the update you installed was the August patch or the September patch? You can find that in settings>about phone>software information>Android security patch level
Also had the same issue after the August security patch. I can't decrypt the files I encrypted on the same phone previously, and I can't encrypt other SD cards either.
