Sony Xperia™ M2 support.
Locking your screen.
You can lock 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.
Before setting up a screen lock, you should activate my Xperia on your phone. This is the only way you'll be able to unlock your phone if you forget your screen lock.
To lock your screen:
From the homescreen, tap the Apps icon
Tap Screen lock
Choose the type of screen lock you want to set up and follow the onscreen instructions
Your screen lock will now be set up on your phone.
