Brightness control doesn't work.

[Saiharish]

I use Lumia 630 and after updating to the windows 10 I'm not able to control the brightness. It just stays at one level and I'm not able set it. I tried many times in the app tray and in the settings > brightness. But i am not able to change the brightness. Please help me!

Have you checked in Extras-> Display->Brightness profile ? check manually.
