Locking and unlocking the screen

If you do not use the phone for a while, the screen will be automatically turned off and 

locked. This helps to prevent accidental touches and saves battery power.
When you are not using the phone, press the 

Power/Lock key   to lock your phone. 

If there are any programs running when you lock your screen, they may be still running 

in Lock mode. It is recommended that you exit all programs before entering Lock mode 

to avoid unnecessary charges (e.g. phone calls, web access and data communications).
To wake up your phone, press the 

Power/Lock key  . The Lock screen will appear. 

Touch and slide the Lock screen in any direction to unlock your Home screen. The last 

screen you viewed will open.

KnockON

You can lock or unlock the screen by just double-tap.
To activate KnockON feature
1 From the Home Screen, Touch  >Settings > Display > KnockON.
2 Place a checkmark on KnockON.
Double-tap the center screen quickly to unlock the screen. To lock the screen, double 

tap the status bar in any screen (except on the camera viewfinder) or empty area on the 

Home screen.

NOTE:
When turning the screen on, make sure you do not cover the
proximity sensor. Doing so will turn the screen off immediately after turning it
on in order to prevent abnormal turning on in your pocket or bag.
