Question

what thing is brightness in dark​

Answer 1

Answer:

To make a glow-in-the-dark toy, what you want is a phosphor that is energized by normal light and that has a very long persistence. Two phosphors that have these properties are Zinc Sulfide and Strontium Aluminate. Strontium Aluminate is newer -- it's what you see in the "super" glow-in-the-dark toys.

Answer 2

Answer:

To recalibrate the setting, turn auto-brightness off in Brightness & Wallpaper settings. Then go into an unlit room and drag the adjustment slider to make the screen as dim as possible. Turn auto-brightness on, and once you head back into the bright world, your phone should adjust itself.
