        //   the later one can be skipped to avoid taking snapshot again. While it still accepts

        //   if both of them change to show at the same time.

        //   handle the snapshot.

        // - The display state is ON. Because if AOD is not on or pulsing, the display state will

        //   be OFF or DOZE (the path of screen off may have handled it).
