The Face recognition feature offers a quick and convenient method to unlock your Galaxy phone. However, the feature may not work properly if the camera is smudged or covered or the lighting is poor. Follow the steps below to troubleshoot the issue.
Common causes of recognition failure
Face recognition may not work as expected in the following cases:
- Low lighting: In dim or backlit conditions, the camera may not capture enough detail to recognize your face.
- Face partially covered: Wearing a mask, sunglasses, a hat or thick-rimmed glasses may interfere with recognition.
- Significant changes in appearance: Wearing heavy makeup, shaving a full beard.
- Camera lens issues: Dust, smudges, screen protectors, or a damaged lens may prevent the camera from capturing a clear image.
How to improve recognition accuracy
If you are having some difficulty using Face recognition, you can follow the tips below.
- Clean the front camera lens using a soft, lint-free cloth.
- Remove any accessories covering your face, such as a mask or sunglasses.
- Use the feature in a well-lit environment and avoid strong backlight.
- Check your screen protector or case to ensure it doesn’t block the camera.

If Face recognition continues to fail, you may wish to re-register your face.
Step 1. Select Settings, then select Security and privacy.
Step 2. Select Screen lock and biometrics.
Step 3. Select Face recognition.
Step 4. Select Remove face data.

Face registration tip
- Face the camera directly, then gently tilt your head upwards.
- To get a full scan of your face, first you’ll need to look directly at the camera.
- After that, you’ll be asked to turn your head up slightly.
Please note: To improve accuracy, hold the phone steady, face forward, and scan your face from various angles.
Please note:
- If you frequently wear glasses, makeup, or hats, registering an alternative appearance could help improve recognition accuracy in various situations.
- It may also help to hold the device steadily and ensure that your face is clearly visible and centered on the screen during the unlocking process.
- Keep in mind that Face recognition is generally considered less secure than other authentication methods such as PIN, pattern, or fingerprint.
- If you have a twin or someone who closely resembles you, it's possible that the device might recognize them as well. This is something to consider when selecting your primary unlock method.
- Device screenshots and menus may vary depending on the device model and software version
