Hi all, I’ve been fixing a broken iPhone X that would bootloop as long as the earpiece/proximity-unit is connected to the logic board. I’ve ordered a replacement-part but it still does the same thing… Also: if I connect the unit while the device is powered on it works absolutely fine. It just hinders the booting-process somehow… Anybody experiences something similar?

I’ve had the same thing happen to me on an iphone 7. In my case it turned out the screen was faulty. and replacing it caused the phone to return to normal function.
