Find your Android device's "Recovery" button combination. Every Android device has a button combination to open the recovery menu; Check your Android device's user manual or online documentation to find this combination.

This usually includes selecting the language and Wi-Fi network.
Sign in to your Google account. When asked, you'll enter the email address and password of the Google account you previously used to sign in to your Android device.
If you don't remember your Google account password, you'll recover it on your computer before continuing.

Press and hold the "Recovery" button combination. This button combination will vary from Android device to Android device, but will typically include the power button, Home button, and/or volume button.
Check your phone's user manual to find out the restore button combination if you don't know it.

Repeat with another screen lock file name.
Touch the Menu button
Select Delete .
Confirm your selection when requested.
Restart Android. Return to the custom recovery app's home screen and select Reboot . Once the reboot is complete, you can open Android without entering a password.
Remove third-party screen lock
Find out the conditions for applying this method. If you know your Android's passcode but can't unlock it because of a third-party screen lock app, use Safe Mode to remove the screen lock app.
Some apps will install malicious apps to protect the screen lock with a password. Using Safe Mode will allow you to delete these applications.
Note that you must know your regular screen lock password to complete this method.
Press and hold the "Power" button, usually on the right side of your Android device. The screen will display a menu.
Press and hold Power off so the screen displays another menu after a few seconds.
On a Samsung Galaxy, you'll tap Restart , then hold the Volume Down button while Android restarts. You can skip the next two steps.
Check the "Reboot" box at the top of the menu.
Select OK below the menu to ask Android to initiate a reboot.
Wait for Android to reboot. Once Android finishes rebooting, you'll see "Safe mode" in the bottom left corner of the screen.
For Android on Samsung Galaxy, remember to press the volume down button during the reboot process to open Safe Mode.
Unlock Android. Now that third-party screen lock apps no longer work, you need to know the regular screen lock passcode on Android.
Open Settings. Swipe the screen down from the top (you'll need two fingers), then tap the Settings gear icon in the drop-down menu.
Tap Apps . It's near the center of the screen.
Choose a third-party screen lock app. Swipe through the list of apps on your Android until you find the screen lock app, then tap it.
Select UNINSTALL . It's near the top of the screen.
Tap OK when asked to uninstall the app without a password.
You can restart Android to normal mode by pressing the power button and tapping Restart (or tapping Power off and pressing the power button again).
