    Working with the face unlock 

    Available from Android™ 4.0 for phones with a front facing camera

    To set up the face unlock feature

    1. From your Home screen, tap > Settings > Security > Screen lock
    2. Tap face unlock, then follow the instructions in your device to capture your face. 
    3. After your face is successfully captured, tap Continue
    4. Select a backup lock method and follow the instructions in the device to complete the setup. 

    Note! The face unlock feature is less secure than a screen lock pattern, PIN, or password. Someone who looks similar to you could unlock your device.  For best results, capture your face in an indoor area that is well lit but not too bright, and hold the device at eye level. 

    To unlock the screen using the face unlock feature

    1. Activate the screen.
    2. Look at your device from the same angle you used to capture your face unlock photo. 

    Note! If the face unlock feature fails to recognise your face, you need to draw the backup pattern or enter the PIN to unlock the screen. 

    To disable the face unlock protection

    1. From your Home screen, tap > Settings > Security > Screen lock
    2. Draw your backup screen unlock pattern or enter your PIN. 
    3. Tap Swipe.
