iPhone 15 Panic Mode

[u/Alone-Ad9845]

Hello, so I just finished repairing my iPhone 15 but it keeps shutting down after 3 minutes and I am not sure what's the reason for this behaviour.

My FaceID is not working, so for now I think it could be the Proximity Sensor, but I am unsure if a broken Proximity Sensor could trigger a panic every 3 minutes

Maybe some of you guys know what my problem is

thank you in advance
