About this guide

Even at the lowest brightness a phone can be too bright in a dark bedroom. Extra dim lowers the screen further.

Other Galaxy phones on One UI 8 should use similar menus; on older One UI versions a few names and positions differ.

Good to know

Extra dim is not the same as Eye comfort shield, which makes the colours warmer: how to turn on Eye comfort shield on a Samsung Galaxy phone.

Reduce transparency and blur, just above Extra dim, reduces visual effects on dialogs and menus to make them easier to see.

In short: Settings, Accessibility, Vision enhancements, Extra dim on.
