Setting a Screen Lock for the First Time
From the Home screen, tap the Menu Key
> Lock screen settings.Tap Select screen lock.
Tap None, Swipe, Knock Code, Face Unlock, Pattern, PIN, or Password.
None: No lock screen is enabled so the screen will never be locked from use.
Swipe: A swipe motion in any direction on the touchscreen will unlock the screen. This is the default Lock screen that simply guards against unintentional actions.
Knock Code: Unlocks the screen using a knock pattern on a 2x2 grid. The first time you set a knock code, you'll see a tutorial with instructions on how to create it. Tap a sequence on the 2x2 grid (from 2 to 8 taps), then tap Continue. Tap your sequence again and tap Continue once more to confirm.
NOTEYou're prompted to create a Backup PIN as a safety measure in case you forget your Knock code unlock sequence.
Face Unlock: Unlocks the screen using face recognition. The phone captures your image to identify you. Keep in mind that Face Unlock is less secure than a pattern, knock code, PIN, or password because it uses generalized shape and dimension to verify your face.
Pattern: Unlocks the screen using a pattern you draw with your finger. The first time you set an unlock pattern, you'll see a tutorial with instructions on how to create it. Read the tutorial, then tap Next. Draw your pattern (connect at least 4 dots) and tap Continue. Then redraw your pattern and tap Confirm.
NOTEYou're prompted to create a Backup PIN as a safety measure in case you forget your unlock pattern sequence.
PIN: Unlocks the screen with a number sequence. Enter a PIN (at least 4 digits) and tap Continue. Reenter your PIN and tap OK to confirm it.
Password: Unlocks the screen with an alphanumeric sequence. Enter a password (at least 4 characters) and tap Continue. Re-enter your password and tap OK to confirm it.
From then on, any time you want to unlock the screen, you'll need to perform the unlock action you set (swipe, face recognition, pattern, knock code, PIN, or password) to gain access to it.
