How to fix auto brightness issues for the Samsung Galaxy S21 FE 5G
If the Adaptive Brightness is main your screen too bright or too dark, then we recommend doing the following:
First off, you can manually adjust the brightness level in the Quick Settings menu. To gain access to this slider, you can use two fingers to swipe down from the top of the screen to find it in the Quick Settings menu. You can also use one finger to swipe down two times from the top of the screen.
Furthermore, the brightness slider can be found in the Settings app by going to the aforementioned Display menu.
We recommend adjust the brightness slide as often as possible. This is because the Adaptive Brightness feature uses machine learning. The more you adjust the slider, the more data the machine learning will receive. Therefore, more brightness adjustments will lead to better accuracy with the Adaptive Brightness feature over time.
To further improve the auto brightness accuracy, we recommend that you avoid blocking the rare cameras of your Samsung Galaxy S21 FE 5G phone as those are used to determine the ambient lighting conditions.
