Set an unlock pattern to secure your and prevent unauthorized use. From the Home
screen, tap > Apps tab (if necessary) > Settings > Lock screen > Select
screen lock > Pattern. This opens a screen that will guide you through how to draw a

in case you forget your screen lock.

the Backup PIN you created when creating your screen lock.
WARNING
Precautions to take when using a pattern lock.
It is very important to remember the pattern lock 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 pattern lock, PIN or password. If you have used all
5 opportunities, you can try again after 30 seconds.
When you can't recall your unlock Pattern, PIN or Password:
< If you have forgotten your 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 at the bottom of the screen. You are
then required to log in with your Google Account or enter the Backup PIN you created.
If you have not logged into a Google account on the phone or you forgot your Backup
PIN, you have to perform a hard reset.
< If you have forgotten your PIN or Password >
If you forget your PIN or Password, you will need to perform a hard reset.
Caution: If you perform a hard reset, all user applications and user data will be
deleted.
NOTE: If you have not logged into your Google Account and have forgotten
your Unlock Pattern, you will need to enter your Backup PIN.
