Why is Face ID Not Working on iPhone 12? Solved!

Check Device Settings

Start by inspecting your iPhone’s settings to ensure that Face ID is enabled. Navigate to Settings > Face ID & Passcode and check if the toggle switch for Face ID is turned on.

If Face ID is enabled, check if you have set up an Alternative Appearance. This feature allows you to enroll a secondary face, such as when you wear glasses or have a different hairstyle. Go to Settings > Face ID & Passcode and tap Set Up Alternative Appearance.

If you’ve recently made changes to your appearance or the environment, you may need to reset Face ID and re-enroll your face. Tap Reset Face ID in the Settings > Face ID & Passcode menu, and follow the on-screen instructions to re-enroll.

Clean iPhone Screen and Sensors

Dirt or smudges on the iPhone’s screen or the TrueDepth camera sensors can interfere with Face ID. Use a clean microfiber cloth to gently wipe the entire screen, including the notch area.

For the TrueDepth camera sensors, use a soft-bristled brush to remove any accumulated dust or debris. Avoid using abrasive materials or liquids, as they can damage the sensors.

Adjust Face ID Position

When using Face ID, make sure to hold the iPhone directly in front of your face, approximately 10-20 inches away. Ensure that your face is well-lit and avoid wearing sunglasses or face coverings.

Look directly at the TrueDepth camera sensors, not at the screen. The sensors need to be able to see your eyes, nose, and mouth clearly to authenticate your identity.

Remove Any Obstructions

Check if there is anything covering the TrueDepth camera sensors, such as a screen protector or case. Remove any obstacles that may prevent the sensors from working properly.

If you have a screen protector, ensure it is correctly installed and does not cover the notch area. Consider removing the screen protector temporarily to see if that resolves the issue.

Check Software Updates

Software updates often include fixes for Face ID issues. Check if there are any pending software updates for your iPhone by going to Settings > General > Software Update. If an update is available, install it and see if that resolves the problem.

Reset All Settings

As a last resort, try resetting all iPhone settings. This will erase Wi-Fi passwords and other customized settings, so make sure to back up your data before proceeding.

Note: Resetting all settings does not delete any personal data like photos, messages, or apps.

To reset all settings, go to Settings > General > Reset > Reset All Settings. Enter your passcode when prompted and confirm the reset.

Contact Apple Support

If all the troubleshooting steps above fail to resolve the “Face ID Not Working” issue on your iPhone 12, contact Apple Support for further assistance. They may provide additional diagnostic tools or repair options.


If you have tried all the troubleshooting steps mentioned above and still facing issues with Face ID on your iPhone 12, it might indicate a hardware problem. In such cases, it’s best to contact Apple Support for expert assistance and potential repair options. Remember, regular software updates, keeping the iPhone screen and sensors clean, and adjusting the position of your face during Face ID scans can help ensure optimal performance. By following these steps, you can identify and resolve common Face ID issues on your iPhone 12, ensuring a seamless and secure user experience.
