Missing sensor mic1: what to test before replacing parts
The mic1 token reports that a required sensor channel associated with a microphone or related flex path did not answer. Its physical location is model-specific.
First diagnostic path
- Verify the exact model identifier from the log.
- Inspect the model-specific microphone/flex connector path.
- Test with a known-good, correct-revision part before microsoldering.
Other causes to keep in scope
- Torn or liquid-damaged flex.
- Connector pin or board-pad damage.
- Missing rail, filter or communication continuity on the board.
How CoreMatch uses this signature
The analyzer combines this token with the panic family, exact device model and compatible verified evidence. It ranks a likely component only when those signals agree, then provides confirmation steps.
Important limitation
Never transfer a mic1 part mapping from another iPhone family without checking the exact model.
