After the release of iOS 6, many people quickly discovered that Apple changed the way the auto-brightness function works, but also the fact that the brightness sensor does not work as it should. Practically, the auto-brightness does not change the brightness settings of the screen, no matter how you set the slider, only after a strong light source is brought close to it. The problem seems to be one of calibration, because after approaching a strong light source, everything works correctly.
Unfortunately, in iOS 6.0.1 the problem was not solved, and unfortunately you still have to resort to applying a light "shock" to the terminal to "wake up" the sensor in it.
