It is always recommended to know a few things about your smartphone when you first get it, such as Samsung Galaxy S9 calibrate auto brightness. As technology evolves, smartphones like Samsung Galaxy S9 and Galaxy S9 Plus are designed to make the best of their resources. That’s how the whole idea of auto brightness started, with the developers wanting to empower the device to adjust the screen brightness automatically, depending on the environmental conditions.


The auto brightness calibration on Galaxy S9 and Galaxy S9 Plus might sound like a fancy name but it’s really nothing more than the effect of a light sensor. Placed right next to the earpiece, this sensor monitors the ambient brightness, deciding what brightness value would work best for your display, under the given circumstances.

If there’s too much brightness where you’re standing, the screen brightness will also go upward, to avoid contrasts and to spare you from eyesores. Just the opposite, when the environment has a dimmed light, the display brightness will also go down, to match the one of the environment.

Practice doesn’t always seem to go by the book, which is why, at times, you might feel the need for an adjustment of this automatic feature. Not happy with how the display looks and feels? Then you will have to:

  1. Grab your smartphone and perfectly cover with your palm the two sensors located left from the earpiece – by doing so, you’re making your Samsung Galaxy S9 “believe” that it’s sitting in a completely dark environment;
  2. Next, without uncovering the sensors in any way, access the Status Bar and tap on the Auto Brightness feature – you will want to move its controller completely to the left;
  3. With the Auto Brightness set to a minimum, turn this feature On and then back Off, as fast as you can;
  4. With the sensors still covered, go out into the daylight, or in a very bright room, or even at a bright desk lamp if you have no other options;
  5. In this new and well-lighted environment, uncover the sensors;
  6. Then, turn the brightness controller back to a maximum level;
  7. Reactivate the Auto Brightness feature and see how it goes.
