Locking and unlocking the screen
If you do not use the phone for a while, the screen is turned off and locked
automatically. This helps to prevent accidental touches and saves battery
power. When you are not using the phone, press the Power/Lock key to
lock your phone.
Secure your lock screen
Lock your screen so that only you can unlock it to access your phone.
To set an unlock pattern, PIN or password for the first time:
1
Touch
> Apps tab > Settings > Lock screen > Select screen lock.
2
Choose from None, Swipe, Face Unlock, Pattern, PIN, or Password.
NOTE: Precautions to take when using pattern lock
It is very important to remember the unlock pattern you set. You will not be
able to access your phone if you use an incorrect pattern 5 times. You have 5
opportunities to enter your unlock pattern, PIN or password. If you have used all
5 opportunities, you can try again after 30 seconds.
When you cannot recall your unlock pattern:
If you logged in to your Google account on the phone but failed to enter
the correct pattern 5 times, tap the Forgot pattern? button. You are then
required to log in with your Google account to unlock your phone.
If you have not created a Google account on the phone or you forgot it,
you have to perform a hard reset.
