My micro SD suddenly has given me this message and later restarted. When it came back all my apps I downloaded were gone.(micro sd is blank or has unsopported filesystem.) I didn't know what to do. I did a quick internet search and i learned an update needed to be made, did that but that message is still there. I've also learned there is no fixing this, unless there's a way. I own another new micro SD card but what I want to know is this; If I can't transfer everything from the defective SD card to the new one, will all my apps be gone? I doubt T-Mobile can help.
