What is Adaptive Brightness for Samsung Galaxy S21 FE 5G?

Adaptive Brightness will automatically adjust the screen brightness on the Samsung Galaxy S21 FE 5G depending on your viewing condition.

If you are looking at your phone while it is dark, for example, then this feature will lower the screen brightness. If you are using your phone in a bright environment, then Adaptive Brightness will increase the brightness level for better visibility.

Should you turn on Adaptive Brightness for Galaxy S21 FE 5G?

We recommend turning on Adaptive Brightness for your Samsung Galaxy S21 FE 5G if you haven’t done so already. Without this feature, you will most likely have to manually adjust the brightness level of the screen any time the ambient lighting condition changes.

If you haven’t done so already, you can enable the Adaptive Brightness on your Samsung Galaxy S21 FE 5G by taking the following steps:

1. To start off, head to the Settings app on your Galaxy S21 FE 5G phone.

If you can’t find the app, swipe up from the bottom of the home screen to find it within a list of installed applications.

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.
