How to Fix Samsung Galaxy S23 Ultra Face Unlock Not Working

Here are some fixes that have the potential to resolve the Samsung Galaxy S23 Ultra Face Unlock not working issue:

Fix 1: Clean the Front Camera

You can try cleaning the front camera of the Samsung Galaxy S23 Ultra when you experience problems with the face unlock. Please ensure no smudges or fingerprints on the camera lens by gently cleaning it with a soft, dry cloth. The camera lens may be damaged or dirty, which may prevent it from capturing clear images of a user’s face, which results in the face unlock system failing to recognize the user.

Fix 2: Check Face Recognition Settings

Ensure that the device’s face recognition settings are set up properly by checking the device’s settings. You can turn on and register your face by going to Settings > Biometrics and security > Face recognition. To unlock your device using your face, turn on face recognition if it is not already on. Follow the on-screen instructions to register your face if it has not been registered.

Fix 3: Improve Lighting Conditions

Try improving the lighting in the area where you are trying to unlock the device if the face unlock system does not work. To ensure your face is well-lit, move to a brighter location or turn on additional lights. The Samsung Galaxy S23 Ultra requires good lighting to recognize the user’s face. The face may unlock and will not work properly if the lighting conditions are poor.

Fix 4: Update Software

If you find a software update for your Samsung Galaxy S23 Ultra, install it. This can be fixed if any software glitches or bugs are preventing the face unlock system from working properly.

Fix 7: Remove the Screen Protector

There is a possibility that a screen protector on your Samsung Galaxy S23 Ultra may interfere with the face unlock feature. Remove the screen protector to see if the face unlock system works. It may be difficult for the camera to capture a clear image of your face if some screen protectors reflect light or cause distortion.

Click Settings > Biometrics and security > Face recognition and select Remove Face data. After that, follow the instructions on the screen to re-register your face. Ensure your face is registered in good lighting conditions and positioned correctly within the frame.

Go to Settings > General management > Reset > Factory data reset to perform a factory reset. If the face unlock system does not work after resetting the device, try registering your face again.
