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 taps 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.
KnockCode
The Knock Code feature allows you to tap the screen with your own Knock Code 
pattern using the screen divided by 4 squares to easily turn the screen on or off. You 
can disable this feature in the Lock screen settings.
NOTE:  
If you enter the wrong Knock Code 6 times, it will compulsorily take you to 
your google account log in/backup PIN.
Use the fingertip instead of finger nail to tap the screen for turning it on or 
off.
When the Knock Code is not in use, you can use Knock On function by 
taping the screen.
