Wow! Never seen anything like it!
I can only give 2 suggestions,
1. Try a hard reset.
2. If hard reset doesn't help, then i would guess its a hardware problem and take your phone in for replacement.
Then try uninstalling all the photo related apps and see wether the problem is solved.
Since photo hub is a system app, the only way to reset it is by a hard reset.
Hard reset is first line of defense? **** no...Wow! Never seen anything like it!
