How to Adjust Brightness of Always On Display on Galaxy S21, S20

In this guide we will show how to change the brightness of your Galaxy S21 or S20 Always On Display on Android 10 with One UI 3 and 2.

What’s the Matter

Always On Display (AOD) is a cool feature on Samsung Galaxy phones with AMOLED displays. It used to show a brief information on the screen without consuming much energy. Only a small part of LEDs are lit while the majority is off.

By default, the brightness of Always on display is set to “auto” on Galaxy S21/S20. But you may want to use the permanent (unchangeable) level and adjust it to your liking to make your AOD look even more stunning.

  • Tap on Always On Display (on the text itself but not the toggle): AOD Settings Galaxy OneUI 2
  • Scroll down to the very bottom.
  • Make sure you have Auto brightness disabled.
