iPhone X — mic2: Power button
Low confidenceVerified sourceMissing sensor
On the iPhone X, mic2 means: Power button / flash flex (rear microphone).
What does this code mean?
Watchdog panic: thermalmonitord no longer receives a response from the rear microphone mic2, carried by the power button / flash flex; with no response for ~3 minutes, iOS restarts the iPhone. No mic2 case found on iPhone 7, 8 or X.
Which part to test first?
Check the seating of the power / flash flex, test with a known-good flex, inspect its connector on the board.
