No need to worry about, we help you...
In this post, we're proving the easiest ways to unlock the pattern lock.
METHOD 1: Unlock Pattern Using Google Account
From here, choose "Enter Google account details" (depending on your device, you may go directly to this option), then enter your primary Gmail account and password. Google will either send you an email with your unlock pattern, or you can change it right then and there.
METHOD 2: Perform a Factory Reset
If you're more concerned with getting into your phone than you are with preserving any data stored on it, a factory reset should work in almost any scenario.
Next, hold the power button down and tap the volume up button once, then your phone should enter recovery mode. From here, use the volume buttons to highlight the "Wipe data/factory reset" option, then press the power button to select it. When the process is finished, select the "Reboot system now" option and you should no longer be locked out of your phone.
