Basics
Lock screen
Pressing the Power key turns off the screen and locks it. Also, the screen turns off and automatically locks if the device is not used for a specified period.
To unlock the screen, press the Power key or the Home key and swipe in any direction.
You can change the way that you lock the screen to prevent others from accessing your personal information.
On the Apps screen, tap Settings →Lock screen and security →Screen lock type, and then select a screen lock method. The device requires an unlock code whenever unlocking it.
If the unlock code is forgotten, take the device to a Samsung Service Centre to reset it.
Pattern
Draw a pattern by connecting four dots or more, and then draw the pattern again to verify it. Set a backup PIN to unlock the screen when you forget the pattern.
