Im here because of my problem with SGA 2.
Few days ago I bought ACE 2 and I found few problems with "external_sd".
So the problems are
1. When I try to create folder it gives me error "Creation failed"
2. When trying to move folder from internal memory to external sd it gives me error like "Moving failed", while copying goes fine.
3. I can move/copy any file to sd card, but sometimes those files got corrupted, gives me error about memory when trying to open pictures, same problem when saved camera saved photo to sd card. Even getting error when trying to play video.
APK files got corrupted too.
4. When I have moved apps to sd card some while apps work great, but after some time cant launch apps because it gives me error about that app doesnt exist.
I tried formatting sd card with pc and android.
Repartition to same firmware with Odin.
Wipe cache, wipe data.
I dunno what causes those error, bugs, glitches. Is it phone or android sytem?
Maybe need to wait update or something?
Tried many sd card and always got same errors.
But when I mounted mine sd card to another phone it worked perfect.
