You can change your display to a dark background with either Dark theme or Colour inversion.
To turn on Dark theme or Colour inversion:
- Open your device's Settings app .
- Tap Accessibility.
- Under Display, turn on Dark theme or Colour inversion.
- Dark theme applies to the Android system UI and apps running on your device. Colours don't change in media, such as videos.
- Colour inversion exchanges colour values. For example, black text on a white screen becomes white text on a black screen. Colour inversion also applies to media, and there can be issues with colour quality or legibility.
Note: If you're using Android 9 or earlier, you can only use one of these settings at a time. For example, if you turn on Dark theme, Colour inversion automatically turns off.
