The Basics
To unlock the phone
If you don’t use the phone for a while, the screen and
backlight will turn off to conserve battery power. To
unlock the phone’s default Lock screen:
NOTE The default Lock screen simply locks the screen to prevent
unintentional actions. For more security to guard against
unauthorized use, you can set an unlock requirement (such as a
Knock Code, pattern, PIN, or password) that will need to be
entered to unlock it.
1. Turn the screen on.
Press the Power/Lock button .
NOTE Avoid covering the proximity sensor when turning the screen on.
Doing so will prevent the screen from turning on.
OR
Quickly double-tap the center of the screen (KnockON).
2. From the center of the screen, swipe in any direction to unlock it.
