The short answer
Check the Face ID settings, camera area and how you are holding the phone. If setup repeatedly fails or an alert says Face ID is unavailable, save the wording and seek model-specific support.
Read the diagram as text
- Read the message. Passcode request, recognition failure or unavailable?
- Check access. Is Face ID enabled for the feature you are using?
- Clear the view. Check the camera area, face position and accessories.
- Escalate clearly. Keep the exact error and any recent damage history.
Describe the failure precisely
Does Face ID fail to recognise you, work on the Lock Screen but not in one app, or refuse to complete setup? Write down the message rather than paraphrasing every outcome as a broken camera.
Keep your passcode private and make sure you can enter it correctly yourself. Do not repeatedly guess. A request for the passcode does not by itself establish a hardware fault, and a working selfie camera does not establish that all Face ID functions are healthy.
Check the settings and camera view
Apple's Face ID support guide recommends checking enabled features in Settings > Face ID & Passcode, keeping the TrueDepth camera unobstructed, and ensuring your face is visible. Some sunglasses can interfere with recognition.
Use an ordinary, comfortable holding position and check whether a case or protector covers the camera area. Orientation support varies by model and software. Follow Apple's instructions for your specific device instead of assuming every iPhone behaves the same way.
Keep app-specific trouble separate
If device unlocking works but a particular app still asks for its password, note the app name and review its own login options. That is a different starting point from a phone that cannot enrol a face at all.
For example, "Face ID unlocks the phone but does not appear in this app" gives support a specific feature to investigate. You do not need to share the app password or a screen containing account information to explain that distinction.
Make software changes deliberately
Apple includes updating and restarting among its checks. Back up before an update, and expect to use your passcode after restarting. If you consider resetting Face ID enrolment, understand that you will need to set it up again; it is not a way to repair physical damage.
Do not make several changes and forget which one affected the result. A brief note of the original error and each check helps if the issue is intermittent. If setup keeps failing, repeated enrolment attempts are not a substitute for diagnosis.
Leave the sensor assembly to trained service
Apple warns against improper work on the Face ID laser system. Do not open the assembly or follow a parts-swapping shortcut. Explain any recent drop, liquid exposure, display repair or camera-area damage before arranging service.
Ask what can be diagnosed, which functions can be checked afterwards and what remains uncertain. Neither a screen replacement nor a generic camera replacement should be presented as a guaranteed Face ID fix without assessment.
Keep these notes for your next step
Useful notes: exact message, whether setup completes, whether unlocking works, affected app and recent repair or damage history.
