🔒 iPhone 15: Why is Face ID not working?

If Face ID on your iPhone 15 still fails after resetting and setting it up again, the problem may be related to the TrueDepth camera system, sensors, or a software issue. First, make sure iOS is fully updated and restart the phone. Check that nothing is blocking the TrueDepth camera area, including a poorly fitted screen protector or case. You can also try resetting all settings without deleting your personal data. If Face ID continues failing, especially if the setup process itself cannot complete, the TrueDepth hardware may need inspection. Avoid attempting DIY repairs because Face ID components are sensitive and security-linked. An Apple Store or authorized service provider can run diagnostics and determine whether the issue is software-related or requires hardware repair. If the phone was recently dropped, exposed to moisture, or had a screen/camera repair, mention that to the technician because it may be relevant.

My iPhone 15 Face ID has stopped working properly, it fails to recognize my face most of the time and asks for the passcode instead. This happens even in good lighting with nothing covering the camera. Already tried resetting Face ID and setting it up again from scratch.
