Front camera not working after screen replacement
I recently changed the screen of my iphone 6 (4.7") and the front camera was not working. When I opened the phone to check if the cable is connected it was. So I tested the camera while the screen was out of the shell body (all the cables were still connected) and the front camera was working just fine. I thought that I had a bad connection and put the screen back on. The camera stopped working again. I did this a few times and the same thing happens.
I have no idea what I am doing wrong, please help me!
Is this a good question?
