Tried searching for this issue, didn't immediately find anything.
My camera will sometimes take a picture, and the only thing the gallery will show is the generic picture icon. If I try to go back to the camera, the screen will just flicker and then go back to the home screen. If I delete the broken picture from the gallery the camera will load, but all it will do is take more broken pictures. This happens with both the stock and vignette camera apps.
When I reboot the phone, the camera will work for a while, but eventually goes back to the same behavior.
Seems like a hardware issues sense both apps are doing it.
