After the recent update at the beginning of December I have problems with my sim card. The phone reads it fine and the basic file structure is there, but i can no longer see the files that are on it. The sim card still shows as nearly full, but I can't view the videos and pictures that are on it. They aren't just hidden either, I can't search them at all. Any ideas?
Solved! Go to Solution.
A SIM card is from your carrier.
Do you mean your MicroSDXC card?
Copy the files from it to a PC and then format it in your phone and then copy the files back.
