Camera shutter won't open
A couple days ago my iPod Touch said that there was not enough storage for me to take any more pictures. There was only 80 pictures and I've had over 150 in the device, so that was odd. Anyway, I took all the pictures off the iPod, and the camera app still won't open, as if it was still had no storage, however, no message pops up saying I have no storage. The shutter just stays closed. If I'm in an app and use the camera in the app, the same thing happens, and it will crash the app after a few seconds. I've already resetted the iPod and had no success. How do I fix this?
iPod touch (4th generation), iOS 6.1.3
