Question :

Is it available to unlock device by something like pictures or image in the video when Galaxy S20 FE is locked by Face recognition?

Answer :

When using face recognition to unlock your device, your phone could be unlocked by someone or something that looks like your image.

Regarding the possibility of the exceptional cases where the current detector can mistake fake image as a live input, the decision logic was already applied to strengthen the anti-spoofing function on Galaxy S20 FE.

However, due to usage of only a single frames from camera there are technical limitations in coping with all spoofing attempts such as high-resolution images.

Thus we do not recommend the usage of face recognition for the high security authentication applications.

And, as Face recognition is less secure than Pattern, Pin, or Password, we recommend to use the Fingerprint recognition, Pattern, Pin, or Password to lock the device.

If you want to reduce the possibility of recognizing faces in photos or videos, tap the Faster recognition switch to deactivate it.

This may decrease the face recognition speed.  (Settings > Biometrics and security > Face recognition > Turn off the Faster recognition)

Additionally if you use your face as a screen lock method, your face cannot be used to unlock the screen when restarting the device again.

To use the device, you must unlock the screen using a pattern, PIN, or password you set when registering the face.

Be careful not to forget your pattern, PIN, or password.

Consider the following when using face recognition:

• Consider the conditions when registering, such as wearing glasses, hats, masks, beards, or heavy makeup
• Ensure that you are in a well-lit area and that the camera lens is clean when registering
• Ensure your image is not blurry for better match results
