I marked a previous post solved and right after that the same error occurred.
Factory reset did not fix the problem.
It happened after i adjusted the camera settings such as white balance and sharpness and turned the MP down to 5.
The pattern isn't as consistent as to when it locks up but its the same problem. I have to hit the home key repeatedly to get back to the main screen, open the camera again and its just a black screen so i have to close it again and then open it.
This is really getting old.
