So I recently got a mini digital camera, and it was working fine and taking pictures. But all of a sudden when I tried taking pictures just now, instead of beeping once to signify that it took the picture, it beeped twice and the "how many pictures left" stayed the same. I've tried turning it on and off, and taking the battery out, but nothing works. If I try twenty times in a row to take a picture, two out of the twenty times actually works. Anyone know how to fix this?
