The auto adjustment is in such a way that it can take place depending on the environmental conditions.

When you hear of Galaxy S9 and Galaxy S9 Plus auto brightness calibration, it actually sounds like it is a fancy name. However, it is actually nothing more than the effect of a light sensor. This sensor is placed next to the earpiece. It monitors the ambient brightness so as to decide the brightness value that works best for your display depending on the given circumstances.

Therefore, if where you are standing there is too much brightness, the phone will also automatically increase brightness on Galaxy S9 and Galaxy S9 Plus. This is so as to avoid contrasts and also spare you from developing eyesores.

  5. Now uncover the sensors
  6. Turn the brightness controller to a maximum level
  7. Reactivate the auto brightness and watch to see how the phone behaves now.
