Back camera doesn't work after screen replacement
I replaced the screen of my iPhone 4S. I've done many before, and I'm good at it, I would like to think.
However, when I tried to go onto the camera it just loads the shutter image and wont go any further. The controls at the bottom flash a few times, and some times it will go back to the apple logo and then onto the lock screen. (Not like a reboot, it only takes about 8 seconds)
I ordered a new camera and replaced it, still the same. I've even swapped it for a one I know works and still the same.
