How to reset Adaptive brightness data on Android 9 (Pie)

Reset Adaptive Brightness Data on Android

Adaptive Brightness is one of the highlight features of the Google’s Android 9 release. It is an improved and AI based implementation of Auto Brightness. Adaptive brightness uses machine learning to understand user’s usage habits and delivers a brightness value suiting his or her taste.

But what do you do if the adaptive brightness is not working very well? You do not have to reset the entire device to make adative brightness recollect data. A better way is to reset only the adaptive brightness values so that it starts the data collection again. You can then hope for a better performance.

Note: Different OEMs have different methods to store data for the adaptive brightness. The following steps will work on stock Android devices, including Google Pixel and Android One phones.

  1. Open the Settings app and go to Apps & notifications.
  2. Look out for the app named Device Health Services. Tap on it when you find it. This app stores the adaptive brightness data on stock Android devices.
  3. Tap on Storage > Clear storage.

As the tool-tip says, it reverts the adaptive brightness to the factory default settings.

Now you can start using the device normally. It will take upto a week for adaptive brightness to adapt to your usage pattern and provide you with an optimal screen brightness in all kind of lighting conditions.
