iPhone panic 0x1000, 0x200000: Front top screen flex (proximity / ambient light sensor)

Panic codes: 0x1000, 0x200000

How to fix it

The panic points to the front top flex (proximity / ambient light sensor).

1. Test with a known-good front top flex.

2. On iPhone 14, an unplugged Proximity Flex gives this code and a restart every 3 minutes.

3. Diode-mode the FPC connectors to find any fault.
