Rear flash and rear microphone not working.
So I bought a used iPhone 6 with a non-working flash and rear microphone. Knowing they are both on the same flex cable (power button) i replaced that cable. This did not fix the problem. I took the just removed flex cable and plugged it into a different iPhone and the flash and microphone worked. So I have narrowed the problem down a bit. It's not the actual flash or microphone or their flex cable. Note: the power button has always worked with either flex cable. I did a complete iPhone restore with no result. Any ideas?
I'm open to soldering and logic board repairs. I want to learn how to do that kind of repair so let this be a project phone for now. Thanks in advance.
Is dit een goede vraag?
