I had the same experience, but have not been able to get my pics back and card won't reformat either in my S3 or on desktop. What did you do to get your pics back?
I have a galaxy s3 and the camera app doesn't work at all. every time i try to access my camera or gallery, the phone just freezes a few seconds, blinks then returns to the home screen. has been doing this for 2 weeks.
