Samsung Galaxy S4 mini support.
Locking your screen.
You can secure your phone so it needs a pattern, PIN or password every time it's turned on, or every time it wakes up from sleep mode (when the screen is off).
You should make sure you've signed into your phone with a Samsung account in case you lose your phone or forget your screen lock.
To lock your screen:
On the homescreen, tap Apps
Tap the My device tab then tap Lock screen
Tap Screen lock
Choose the type of screen lock you want to set up and follow the onscreen instructions
Your chosen screen lock will now be set up on your phone.
