The Galaxy S7 has a new interactive Personalized Automatic Brightness Control that learns and stores the display brightness settings that you make for varying ambient light levels, so from then on you get your own customized personal visual brightness preferences instead of some pre-programmed manufacturer settings found in other smartphones, tablets, and TVs. It is the first smartphone, tablet, or TV to do Automatic Brightness correctly. When Automatic Brightness is turned On (under Display Settings), if you adjust the Brightness Slider, the Galaxy S7 will remember your setting along with the current ambient light level that is measured by its Ambient Light Sensor (ALS), which is located next to the front facing camera just above the top of the display. From then on the Galaxy S7 will automatically adjust the screen Brightness by measuring the current ambient light level and then adjusting the screen Brightness based on the settings you’ve previously made, so you’ll get a customized screen Brightness setting that you’ve previously trained it to produce for the current level of ambient light – and you can continue to tweak and adjust it as needed.
