If you’ve forgotten your screen lock pattern, you have up to five attempts to try and unlock your phone.
If this fails, you can unlock your phone by entering your Google Account user name and password.
On the unlock screen, enter your lock pattern.
After the fifth attempt, when you’re asked to wait for 30 seconds, tap OK.
If the display goes off, press the
button to turn the display back on, and then press the bar on the lock screen and slide your finger down to unlock the screen.
Tap the Forgot pattern? button in the lower right corner when it appears.
Enter your Google Account name and password, and then tap Sign in.
You’ll then be asked to create a new screen lock pattern. If you no longer want to do so, tap Cancel.
