What to do if the screen brightness changes automatically on your Samsung Galaxy device

Your Samsung Galaxy device may change screen brightness automatically depending on the surrounding lighting conditions, device temperature, or battery level. Screen brightness may also change to help protect the device during overheating or heavy usage, or to extend battery usage time when the battery level is very low.

To adjust the screen brightness from the Quick panel, follow the steps below. You can manually increase or decrease the brightness level depending on your environment or viewing preference. If Adaptive brightness is enabled, the screen brightness may continue to adjust automatically based on surrounding lighting conditions.
