iPhone 7 slow boot, home button not working
I bought a faulty iPhone 7, the screen was broken. So I put a new screen on, only the home button extension cable was torn, so the iPhone was booting slow and the home button didn’t work. Everything else worked fine once it booted.
Now I’ve replaced the screen again, but the home button still doesn’t work, it still boots slow and now also the microphone isn’t working anymore. It was working fine before. Also the camera and front speaker are working just fine.
Can this be the audio IC? I didn’t do anything weird with the phone or the motherboard, and it was definitly working before, or what else could it be?
Is this a good question?
