How to solve the problem that Apple iPhone Face ID cannot be recognized/not easy to use/cannot be entered

When using iPhone, some users may find that the phone cannot recognize faces or suddenly cannot be used. Today we will analyze the reasons and try to solve these problems.

When iPhone Face ID needs to be unlocked, the TrueDepth camera will intelligently activate and collect accurate depth data and infrared images to identify the user.

When the iPhone face cannot be recognized, you can troubleshoot the following problems:

1. When using iPhone Face ID, you need to make sure that the relevant functions in Settings-Face ID and Password are turned on.

2. Check the phone protective film. If the full-screen tempered film blocks the camera, or there is dirt near the TrueDepth camera, or the front camera is covered by dust or moisture, it will affect the successful unlocking of Face ID.

3. If you are wearing sunglasses or a hat, it will also affect Face ID recognition. You can take it off to complete the recognition or unlock it before wearing it again.

4. Pay attention to the surrounding environment: When strong light shines on the face, the strong light will cause some structural changes to the face, so you need to pay attention to the surrounding light when entering or unlocking with Face ID.

5. Make sure you are facing the TrueDepth camera. The system will detect whether your eyes are looking at the screen, and you need to look at the screen according to the prompts to set up and unlock.

Face ID works correctly on all iPhone 13 and iPhone 14 models with iOS 16, whether in portrait or landscape mode. With earlier models, Face ID only works properly on iPhone when the iPhone is in portrait mode and you're facing the TrueDepth camera.

6. Pay attention to the distance and angle: Face ID recognition has a distance limit. It cannot be recognized if it is too close. You can control the distance between the phone and the face within 20-25cm, and the face and the phone are facing forward. Yes, if the relative angle of holding is too large, it will not be recognized.

7. It may be caused by a bug in the mobile phone system. You can try restarting the device and trying again. If it still doesn’t work, you can consider using the Senior iPhone Repair Tool to repair the system.

In addition, you can also try clicking "Set Alternate Appearance" to set up an additional Face ID to increase the probability of successful unlocking.
