Remove third-party screen lock

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.
