screen with a pattern and/or PIN as a backup.

It is very important that you remember the screen unlock information you

times, tap Forgot pattern? You will be required to sign in with your Google account and
prompted to create a new unlock pattern.
If you have set a backup PIN, you can unlock the screen by entering the backup PIN.
If you haven't created a Google account on the phone or you forgot your PIN or
Password, you need to perform a hard reset.
