front facing camera doesn't work after screen replacement.
I got my display replaced a few days ago, but now the front facing camera will not turn on. In the camera, it goes black and freezes after turning it around. In apps that have access to my camera, the option does not exist. There is also some kind of spotty halo-like effect going on at the top of my screen, although I'm not sure if this is related or not. Does anyone know how to fix this or if Apple will be able to fix the problem?
iPhone 5, iOS 8
