Front camera does not work after screen replacement.
I have done many repairs on several iPhones of all models and have always been able to solve the issues I run into but I have recently repaired an iPhone 6s Plus screen that went bad. I disconnected the battery like I always do before disconnecting the display on the phones and I then gently disconnected the old display and swapped out the camera to the new display and connected everything without an issue. I then reconnected the battery and reset the iPhone by holding the power button and home button simultaneously. Everything works on the phone except for the front camera. Whenever I switch to the front camera the phone's camera freezes and stays black or it switches back to the rear camera. I have tried swapping different screens with functioning cameras and have yet to solve the issue. I do not know what the problem is.
Is this a good question?
