The main reasons why Face ID might not be working include the following:
- The TrueDepth camera system may be blocked or dirty, preventing the sensors from reading the face properly.
- The user's face might not be positioned within the frame correctly, or the iPhone is held too close or too far.
- Face ID may have trouble recognizing the face if there are significant changes such as wearing a mask, sunglasses, or certain hats.
- Software glitches or outdated iOS versions can cause Face ID to malfunction.
- Hardware issues, such as damage to the TrueDepth camera or face sensors, can cause Face ID to stop working.
- In some cases, resetting Face ID or rebooting the device may fix the problem.
Checking and cleaning the camera, ensuring proper positioning, updating software, and resetting Face ID are good initial troubleshooting steps.
