Once it is set, you can change it on the Change
screen lock menu.
Caution: You need to create your Google account
first before you set an unlock pattern.
NOTE:
Precautions to take when using a 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, touch Forgot pattern?. 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 factory
reset.
