Adjust screen brightness

To set your screen's brightness any time, open quick settings and slide .

Your phone uses Adaptive brightness to automatically adjust your screen to the light around you. When the feature is on, you can still fine tune the brightness in quick settings.

To turn Adaptive brightness on or off, go to Settings > Display > Adaptive brightness.

If the brightness slider in quick settings doesn’t go high enough, you can make your screen extra bright.

Use extra brightness when you:

• Are in direct sunlight and want to see through heavy glare
• Review or edit photos and videos on location and want to check for accurate exposure and detail
• View movies or games and want to see the peak highlights and full color depth
• Need emergency visibility and want to use the screen as a temporary light source (alternative to the flashlight), or remain visible in high-contrast environments

The bump in brightness uses a lot of battery power (and can cause eye strain in darker environments), so when you don’t need extra brightness, turn it off.

To adjust this setting:

1. Go to Settings > Display.
2. Turn Extra brightness on or off .

You can also make the screen extra dim if the slider in quick settings doesn't go low enough.

Adaptive brightness uses the ambient light sensor to adjust your display brightness automatically. When you change the brightness slider, your phone learns your preferred levels for various lighting environments. Ideally, you’ll need to use the slider less and less.

If Adaptive brightness stops working as desired, you can reset it and then retrain it.

1. Go to Settings > Apps > See all # apps.
2. Tap > Show system apps.
3. Search for “Device Health Services” then tap Device Health Services.
4. Tap Storage & cache > Clear storage > Reset adaptive brightness.

If you prefer to manually adjust brightness, go to Settings > Display > Adaptive brightness and turn Use adaptive brightness off .

If Battery saver is on, the screen dims when the battery gets low.
