It would be nice if samsung could finally solve problems with SD catds on Android 11. My S20 5G has beem having diffirent problems all the time after android11 release on this phone.
It would be really nice if apps could get to Sd card.
Annoyingly stupid from samsung to go with S21 based android os on S20 as hardware is so diffirent (my point to say better in S20, short testing with preordered S21 was enough and changed back to S20). You could have done it better and really done work to support lost hardware from "old" models...
Apps can define for themselves whether they support being transferred to SD cards. It's not up to Samsung. Apps are slow on SD anyway, it's really for photos, videos, music, documents, backups.
