Screen brightness automatically too dim or bright
Adaptive brightness uses the ambient light sensor and machine learning 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 to retrain the system.
1. Go to Settings > Apps > See all # apps.
2.
Tap > Show system.
3. Search for “Device Health Services” then tap Device Health Services.
4.
Tap Storage & cache > Clear storage > .
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.
