How to use Extra dim on a Samsung Galaxy phone
In short
Open Settings, Accessibility, Vision enhancements, then tap Extra dim and turn it on. The screen goes darker than the lowest brightness setting allows. It can also be switched on from the quick panel.
Well, it is not nice when your phone still glares at you in a dark bedroom, even at the lowest brightness. Extra dim can help with that.

Steps
- 1
Open Vision enhancements
Open Settings, tap Accessibility, then Vision enhancements. On our Galaxy S26 it is the first row under What's new in One UI 9.

- 2
Scroll down, tap Extra dim and turn it on
On the Vision enhancements page, scroll down and tap Extra dim. Turn on the switch at the top, which reads Off until you do.
On our Galaxy S26 the page says Dim the screen beyond the minimum brightness for more comfortable viewing. Extra dim shortcut, Intensity and Turn off after restart sit below it; the last two stay greyed out while Extra dim is off.

Or use the quick panel
Samsung says Extra dim can also be switched on from Quick settings, the panel you swipe down from the top. When you edit the panel, tap Add a control. On our Galaxy S26 the Extra dim button is in the Accessibility group of that list. Add it and it is one tap away at night.

If you do not see this option
- You cannot find Extra dim Samsung lists Extra dim among its Vision enhancements, next to Reduce transparency and blur. Our A57 named the page Vision enhancements. Source: Galaxy device Visibility enhancement features
- The quick panel has no Extra dim button Samsung says that if the icon does not appear in the Quick settings panel, you can add it to the panel. Source: Reduce eye strain on your Galaxy phone or tablet
If this does not work
- The screen is not dim enough Samsung says to touch and hold the Extra dim button in the quick panel to open its settings, then drag the Intensity slider.
- Extra dim switches off when you restart In the Extra dim settings Samsung lists a Turn off after restart switch. Turn it off to keep Extra dim on after a restart.
- Want to turn it on without the panel? Samsung lists an Extra dim shortcut in the Extra dim settings. Open Extra dim shortcut and switch on the toggle at the top.
- Screen too dark to see in daylight? Pull the Quick settings panel down with two fingers from the top edge, then tap the Extra dim icon.
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.
At night you may find Dark mode more comfortable: Samsung says your menus, settings and preloaded Samsung apps then use a darker theme. Eye comfort shield and Extra dim are there to help as well. Samsung says Dark mode can run on a schedule from sunset to sunrise or at custom times; see how to turn on Dark mode.
