I'm an Offical Apple phone repair tech. A lot of things stop working once you place new parts in, things that have even thrown me for a loop and made me think I did the repair wrong. I replaced a display, and the vibration and camera stopped working properly. I thought I damaged the haptic feedback motor (That I didn't even remove) You have to sign into apple's repair website, and 'run a diagnostic' in order to get the vibration function to work again after you swap a part on some models. They all do some weird shit.
Sometimes swapping a camera on a model will cause the camera in app to run at like 3 fps or Face ID will stop working until you validate the parts on their repair site. It's shit.
Backed the kickstarter, still excited. Even in its current state it's one of the more interesting games I've ever played. There's probably a reason no one else has tried to make star citizen before. If SQ42 ever launches, hopefully in a decent state, assets will start getting moved to the multiplayer side of things.
