I have replaced the screen on an iPhone7 Plus. Everything worked before. Now it has a long boot time and the volume controls, vibrator, sound, microphone, speaker front facing camera, home button all do not work, but the slide button for mute does work. I have tried it changed it back to the old screen and still does not work. Switched back to the new screen and of course does not work. I decided to unplug the top flex cable that has the camera prox sensor and ear speaker on it, now it the volume controls, sound and voice works. This is a new flex cable for the camera and prox sensor. Also the boot time is normal. If I plug it back in then everything goes back to not working again. Any ideas on this?
If things work without the FCAM flex and they don’t when plugged in it sounds like a bad FCAM flex. FWIW…my username is @refectio, not @minho
Whoever replaced your screen: Wasnt wearing the proper equipment (static band so that the delicate electronics wont be destroyed)Replaced it incorrectly so that some components are failing.Unfortunately at this point there is nothing that can be done. Over time more and more of the device will deteriorate and stop working. You need to 1. get a new phone. 2. Write a bad review for whoever replaced it. 3. Complain to whoever fixed your screen, they are unproffesional and not good at their job.
