: Is it true that one can unlock the device using a picture when the Galaxy S10 series is locked by Face recognition?
When using face recognition to unlock your device, your phone could be unlocked by someone or something that looks like your image. As Face recognition is less secure than Pattern, Pin, or Password, we recommend to use Fingerprint recognition, Pattern, Pin, or Password to lock the device.
Additionally if you use your face as a screen lock method, your face cannot be used to unlock the screen when turning on the device. 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.
