Galaxy S9: How To Calibrate Auto Brightness

Most of the Samsung smartphones have made the auto brightness feature a brand signature. How does the auto brightness feature work? Well, if you are also wondering the same then the answer is quite simple. The Samsung smartphones are built with a special sensor which takes note of the ambient brightness. The sensor is mounted next to the earpiece. This automatically increases or decreases the screen brightness depending on the surrounding light intensity.

It works in such a way that during the times when you are seated in a dark place, the brightness of your smartphone will decrease. But when you are in a brightly lit place, your screen’s brightness will increase. This setup is of great significance since it enables you to take advantage of the optimal display brightness at all times.

It however comes a time when you realize that the auto brightness feature on your Galaxy S9 is no longer working as before. When this happens, you tend to wonder what could be the problem. In such a scenario, you will realize that the brightness of your screen will remain dim even when it should be getting brighter. As a result of the lack of optimal screen display brightness, you may not be able to see whatever is being displayed on your screen.

One recommended DIY solution to this problem is calibrating the Auto brightness sensor. We have gone ahead and consolidated the instructive points into major steps as shown below on how you can calibrate the Auto brightness sensor on Samsung Galaxy S9 smartphone.
