Forgot unlock pattern for my samsung galexy prevail

If you forgot the unlock pattern you can just click the forgot pattern option on the bottom of the screen. Just get the pattern wrong 5 times and wait 30 seconds and the button should appear. Once you press the button you will be taken to a screen where you can input the google account associated with the phone. It will unlock the phone for you if you know the google account username and password. Otherwise you're gonna have to do a hard reset on the phone. This will factory reset the phone.
