49 The Basics
Locking the Screen
You can lock your phone so that only you can unlock it to make calls, access
your data, buy apps, and prevent unauthorized use.
Setting a Screen Lock for the First Time
1. From the Home screen, tap the Menu Key > Lock screen settings.
2. Tap Select screen lock.
3. 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.
NOTE You'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.
NOTE You're prompted to create a Backup PIN as a safety measure in case you forget your
unlock pattern sequence.
