Screen brightness is not changing automatically after enabling option. 

Check Automatic Brightness option from Settings->Display->Brightness
and press OK. Screen brightness should be changed automatically as
per light conditions.

<!-- Array of light sensor LUX values to define our levels for auto backlight brightness support.
The N entries of this array define N + 1 control points as follows:
(1-based arrays)
Point 1: (0, value[1]): lux <= 0
Point 2: (level[1], value[2]): 0 < lux <= level[1]
Point 3: (level[2], value[3]): level[2] < lux <= level[3]
...
Point N+1: (level[N], value[N+1]): level[N] < lux
The control points must be strictly increasing. Each control point
corresponds to an entry in the brightness backlight values arrays.
For example, if LUX == level[1] (first element of the levels array)
then the brightness will be determined by value[2] (second element
of the brightness values array).
Spline interpolation is used to determine the auto-brightness
backlight values for LUX levels between these control points.
