Getting started
Lock screen
Pressing the Side button turns off the screen and locks it. Also, the screen turns off and
automatically locks if the device is not used for a specified period.
To unlock the screen, swipe in any direction when the screen turns on.
If the screen is off or the Always On Display is on, press the Side button or double tap the
screen. For more information about the Always On Display, refer to
Editing shortcuts
You can change the shortcuts at the bottom of the locked screen to other apps or
features you want.
Touch and hold on the locked screen, tap the shortcut icon, select an app or feature you
want, and then tap Done.
Changing the screen lock method
To change the screen lock method, open Settings, tap Lock screen and AOD → Screen
lock type, and then select a method.
When you set a pattern, PIN, password, or your biometric data for the screen lock
method, you can protect your personal information by preventing others from accessing
your device. After setting the screen lock method, the device will require an unlock code
whenever unlocking it.
You can set your device to perform a factory data reset if the unlock code is entered
incorrectly several times in a row and the attempt limit is reached. Open Settings,
tap Lock screen and AOD → Secure lock settings, unlock the screen using the
preset screen lock method, and then tap the Auto factory reset switch to turn it on.

Indicator icons appear on the status bar at the top of the screen. The icons listed in the
