Good to know

  1. The recording shows a real increase: the slider thumb moves from left-of-center to the right of the track.
  2. Adaptive brightness stays on throughout; the manual drag sets the level the adaptive system works around.
  3. Searching for brightness is faster than walking Settings > Display by hand, and lands on the same Display page.
