Repair and disassembly information for the second-generation iPhone SE that was announced and released in April of 2020.

iPhone se2 mic1 constant reboot

Hello users, of ifixit. Today, I want to talk about, a device, that I own, that's constantly rebooting due to mic1, I know this issue, is common, with this, specific iphone. Because there's a defect, on the logic board, where the signal, gets lost under, the sim tray. So I took some, diode readings, on the corresponding pins, responsible for the microphone. The following results are 7th pin, gave 0.259, and 8th pin gave 0.279, so I need, second opinion. What do you think, is the likelihood of this issue, the logic board, or the flex charging assembly.🤔

Update (03/04/25)

Update: I tried applying pressure, while testing, the diode readings, on the corresponding pins, for the microphone, there wasn't any significant change, or open line.

The stable but low readings, even under pressure, suggest the problem’s upstream of the flex connector. A shorted cap or corroded trace near the connector (common under the SIM tray in SE 2s) fits the pattern. Water damage or a manufacturing flaw could’ve started it.
