i got the OTA and all was well. definitely used the camera since it installed. today, i go for the camera and get a black screen. i see the focus box, but no on screen image. i hit the shutter button just to see if it would work blind, and the app froze. i could exit out the home screen, but eventually it would ask if i wanted to force close the camera. no other apps installed. tried a power off reboot, no good. tried a power on battery pull, no good. WTF?
