You might know about the auto-brightness or adaptive brightness feature if you have a mid to high-end Android device. Adaptive Brightness is a smart feature that adjusts your screen’s brightness based on the ambient light around you.

Most of the modern Android smartphones arriving these days have this feature. It’s a feature that helps your phone learn your preferred screen brightness in different lighting conditions.

Your Android phone’s ambient light sensor measures the light around it and adjusts the screen brightness to match. It’s a brilliant feature, but sometimes it doesn’t work as expected.

If the light sensor or the Adaptive brightness feature is not working correctly, your phone will fail to adjust a comfortable brightness level under different lighting conditions. So, if you are facing issues related to adaptive brightness on Android, you are reading the right guide.

5) Check Adaptive brightness in the Safe Mode

If Adaptive brightness is still not working, your phone might have a hardware-related issue. Adaptive brightness depends on the light sensor, so if the sensor malfunctions, Adaptive brightness won’t work.

Check the Sensors

You can use third-party apps like the Sensor test to verify whether the sensor is working. The app will tell you if the Adaptive brightness sensor is functioning correctly or not.

If the app doesn’t help or shows you a negative report, you must take your phone to a service center to fix the problem.

7) Use Velis Auto Brightness App

Sometimes, Adaptive brightness issue occurs due to a bug within the operating system. So, to eliminate such bugs, you need to install the latest version of Android software.

Android updates often contain bug fixes and security patches crucial for any device. So, update the Android software to ensure stability & new features.
