43 The Basics
Locking the Screen
You can lock your phone so that only you can unlock it to make calls, access
your data, buy applications, and prevent unauthorized use.
Setting a Screen Lock for the First Time
1. From the Home screen, tap the Apps Key > Settings > Lock
screen.
2. Tap Select screen lock.
3. Tap None, Swipe, 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.
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, 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 will 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 Follow the on-screen instructions to create a backup PIN number in case you forget your
pattern.
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 will need to
perform the unlock action you set (swipe, face recognition, pattern, PIN,
or password) to gain access to it.
