The Basics
Locking the Screen
You can lock your screen so that only you can unlock it to make calls,
access your data, buy applications, and prevent unauthorized use.
Setting a lock screen
1. From the Home screen, touch the Apps Key > Settings > Lock
Screen.
2. Touch Select screen lock.
3. Touch None, Touch and hold, Swipe, Face Unlock, Pattern, PIN or
Password.
None: No lock screen is enabled so the screen will never be locked from
use.
Touch and hold: Touch and hold the lock screen to unlock it.
Swipe: A swipe motion in any direction on the touchscreen will unlock
the screen.
Face Unlock: Unlocks the screen using face recognition. Keep in mind
that Face Unlock is less secure than a pattern, PIN or password because
it uses generalized shapes and dimensions 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 and touch the Next
button. Draw your pattern (connect at least 4 dots) and touch the
Continue button. Then redraw your pattern and touch the Confirm
button.
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 touch the Continue button. Reenter your PIN and touch the
OK button to confirm it.
Password Unlocks the screen with an alphanumeric sequence. Enter a
password (at least 4 characters) and touch the Continue button. Reenter
your password and touch the OK button to confirm it.
