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:

1. Turn the screen on.

   NOTE

   Avoid covering the proximity sensor when turning the screen on. Doing so, immediately turns the screen off.

   • Press the Power/Lock Key (on the back of the phone). The default Lock screen will appear.

     OR

   • Quickly double-tap the center of the screen (KnockON).

   NOTE

   If you set up a Knock Code in the Screen lock setting, KnockOn won’t work, but you can tap your sequence to turn the screen on and unlock it at the same time.

2. From the center of the screen, swipe in any direction to unlock it.

   • To use a shortcut, swipe the shortcut icon (at the bottom of the screen) in any direction. The screen will unlock and launch the app.

     
   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, password, or face recognition) that will need to be entered to unlock it.
