Display
You can set the screen brightness, color scheme, and Dark mode according to your
preferences.
1. Adjusting brightness
Go to Settings > Display > Brightness level, and enable Automatic brightness.
Your phone will automatically adjust the screen brightness according to the ambient
lighting conditions.
You can manually adjust the screen brightness using either of the following methods:
• Swipe down from the top right of the status bar to open the notification panel. Drag
the slider to adjust the screen brightness.
• Go to Settings > Display > Brightness level. Drag the slider to adjust the
screen brightness.
2. Setting a color scheme
Go to Settings > Display > Color scheme, and select a color scheme that you
prefer. Auto mode will be easier on your eyes and is therefore recommended.
3. Enabling Dark mode
In low light conditions or at night, you can enable Dark mode to apply a darker color
scheme, which helps to prevent excessive screen light from irritating your eyes.
Lock screen
Use your device’s screen lock features to secure your device. By default, the device locks
automatically when the screen times out.
Go to Settings > Always-on display & Lock screen > Sleep, and select a sleep
period. Your phone is automatically locked if no operations are performed within this
period.
