After taking a picture, my iPhone keeps turning off and then on with the spinning wheel on the screen, then it will go to my passcode screen for about 1-2 seconds and then process will repeat itself. When I try to quickly type in the passcode, the phone does not pick anything up. I held down the power button, and the apple logo came up, but the process just kept on repeating. Does anyone have any insight as to what is going on? Any help would be greatly appreciated!
