iPhone 14 Pro Max — sensor array 0x80000: Front sensors flex

High confidenceVerified sourceSMC: silent sensor

On the iPhone 14 Pro Max, 0x80000 means: Front sensors flex (proximity).

What does this code mean?

SMC “BSC failure” panic: the system management controller (built into the SoC) periodically waits for a response from each mandatory sensor; here, the proximity sensor on the front flex has stopped responding. With no response, it forces a restart, which repeats roughly every 3 minutes (≈180 s) as long as the sensor stays silent. Reproduced on iPhone 14 Pro by disconnecting the proximity sensor (DFRWS 2025).

Which part to test first?

Inspect the front sensors flex (proximity / ambient light) and its connector, then connect a known-good flex to see if the restarts stop; diode mode on the connector if in doubt.
