Keep in mind that:

• If your phone has been locked for more than 4 hours, face matching won't work until you first unlock with another method.
• Looking at your phone can unlock it, even when you don't intend to.
• Your phone can be unlocked by someone who looks a lot like you.
• Your phone can be unlocked by someone else if it's held up to your face while your eyes are open. Keep your phone in a safe place. To prepare for unsafe situations, you can turn on lockdown.

1. Go to Settings > Security and privacy > Device unlock > Face unlock.
2. If you haven't yet set up a screen lock, you'll need to set up a backup screen lock method.

3. Follow the onscreen instructions. Be sure to frame your entire face with the outline.

   Face matching data is stored securely on the phone.

4. Select face unlock options.

Whenever you turn on or wake the phone, it will search for your face and unlock the screen when it recognises you.

Show your face to the lock screen.

If it doesn't recognise you, it stays locked and displays one of these icons.

Icon	How to unlock
	Use your password, PIN or pattern
	Use the fingerprint sensor

1. Go to Settings > Security and privacy > Device unlock > Face unlock.
2. Unlock your phone.

3. Tap Delete face data.

   The phone will no longer recognise your face and the data is deleted. To turn it on again, set up face matching again.

If you're having trouble getting the phone to recognise your face:

1. Go to Settings > Security and privacy > Device unlock > Face unlock.
2. Unlock your phone, then tap Redo face scan.
3. Make sure that you are in a well lit environment. Avoid low light, strong light and backlit environments to ensure that the face image is clear.
4. Follow the onscreen instructions.
