My S-III decided two days ago that my memory card is "Blank or has unsupported files". Clicking on this prompts me to Format said memory card which actually has lots of pictures and music on it that I don't want to lose. My wife's S-III did the same thing and finally was convinced that there actually was compatible data on its card. I don't remember how long she waited, but we are talking weeks rather than hours. I have tried restarting, off/on, remove memory card and reinsert, connect to PC (although mainly to sync music to phone rather than card).
Does anyone know WHY this happens or HOW to fix it?
I have had the phone for, I think, 8 months. Same memory card that whole time.
