battery saver won't reduce brightness

Hi every one , i have this problem when i was playing online before i was using battery power so i put auto active battery saver on 20% when was get to that level battery saver was been activated and reduced brightness level with it so i was plugging in the charger but no it doesn't reduce brightness. and i made a lot of searching on the web but unfortunately i wasn't able to find a solution and there is no thing wrong in settings. it will be great if some one can help me with this.

Could just be a computer problem if the drivers for it are not installed. You also need to postnot attach logs, since not everyone is using a computer to view this site.

Hmmm i don't know. there is driver for what Exactly? and it was fine before.

Yes there is a driver and also the screen uses the camera to detect ambient light. Could just be an update to the display driver that caused it or something else.
