I just got mg SGS2 and the camera app is not working. The first day when I got it, the camera worked. I tried to change the camera filter and it said "Camera Failed" so I thought nothing of it, as long as it took pictures that was fine with me. But then the next day I tried using it and now it doesn't want to do anything. It boots up and stay frozen at a black screen with the camera reticule/grid, and I'm in a well lit area but its just all black. The front facing camera was working though. So I turned off my phone and turned it back on thinking a reboot might help. Now not even the front facing camera works! Sometimes it will say "Camera Failed" or just stay at a black screen. Is there anyway I can fix this? I'm on Gingerbread 2.3.6. I have never flashed anything to this phone or done any hacks to this phone, its all stock.
