How do I Reset the Lock Pattern on my Samsung Galaxy Tab® if I forget it?
If you forget your device's lock pattern, you can reset it using your Google™ Account credentials. When you enter the wrong unlock pattern too many times, you should see an option at the bottom of the screen that says Forgot Pattern. Touch this option and your device will ask you to sign in using your Google Account credentials. You may also use your backup PIN or Password (if applicable) on this screen. If you have forgotten your Google Account credentials, visit the Google website to recover them. If you still cannot get your Google Account credentials, contact your wireless carrier for additional options.
