Setting Screen Lock on Your Samsung Galaxy Tab A? (SM-P550, SM-T550, and SM-T350)
Increase your mobile device's security by setting up a screen lock. Pattern, PIN, Password and Fingerprint locks provide better protection than Swipe lock and are all configured from the Screen lock type menu.
Set up a Lock Screen Lock
From the Home screen, touch Apps > Settings > Lock screen and security.
Touch Screen lock type.
For this example, touch Pattern. Alternatively, touch PIN or Password and follow the steps to set up a numeric or password lock.
If you have previously set up a different type of lock, you will be required to enter your credentials.
Create a screen unlock pattern by connecting at least four dots in vertical, horizontal, or diagonal directions. Lift your finger from the screen when finished and touch CONTINUE.
Draw the pattern again and touch CONFIRM.
Select how much notification information you want to display on the lock screen. Then, touch DONE.
Adjust this setting at any time in Apps > Settings > Lock screen and security > Notifications on lock screen > Content on lock screen.
