Screen settings
You can change the screen’s behavior, brightness, viewing size and quality. For example, select a bigger font or display size for easier reading or change the icons you see in the status bar.
If you want to change your background, see Background. To change how long you want to have the screen on before it is turned off, see Turning the screen on or off.
To change a screen setting
- Find and tap Settings > Display.
- Tap the setting you want to change.
- Use the sliders, checkboxes or additional menus to adjust.
Image quality settings
Color gamut and contrast enhance the quality of photos and videos when viewing them on your device.
Video image enhancement improves the visual quality of videos when you view them on your device using X1 for mobile. With this feature, videos recorded in the SDR mode are played with HDR-like quality.
Note
When the Creator mode is selected in Color gamut and contrast, Video image enhancement cannot be used.
Hint
Video image enhancement is available only for certain applications.
White balance
Select one of the preset settings. If you select Custom, you can use the sliders to adjust the white balance. To revert to the default setting, select Medium.
Brightness level
Adjust the brightness level with the slider. You can also enable Adaptive brightness to automatically optimize brightness based on surrounding light.
Note
If your device has an OLED display, avoid displaying very bright or static images for a long period of time. This may cause an afterimage or coloring to remain on the screen.
Auto-rotate screen
Set the screen to rotate automatically when the device is turned, or set it to stay in portrait view.
Hint
Even if the Auto-rotate screen function is disabled, you can rotate the screen manually by tapping 
(Rotate icon) in the navigation bar.
Night Light
Night Light switches the color of the screen to amber. This makes it easier to view the screen in a darker setting, and also makes it easier to fall asleep.
Prevent accidental operations with screen off
You can prevent your device from being activated by mistake while placed in a pocket or a bag. Tap the Prevent accidental operations with screen off switch to enable or disable the feature.
To change a lock screen setting
