specified period. This helps to prevent accidental taps and saves battery
power.
To unlock the device, press the Power/Lock Key and swipe the screen in
any direction.

it on or off.

the bottom or on the top of the screen.

The Knock Code feature allows you to create your own unlock code using
a combination of knocks on the screen. You can access the Home screen
directly when the screen is off by tapping the same sequence on the
screen.

If you enter the wrong Knock Code 5 times, it will compulsorily take you to
your Google account log in/backup PIN.
