Why isn't the back light of my soft touch buttons changing the intensity based on the external light condition?

back light of soft touch buttons lumia 1520

Hello, the back light of soft touch buttons of my lumia 1520 doesn't chance his intensity based on external light condition. It is normal?
How does your?
Mine is always at full brightness

Mine always stays lit and doesn't change at all. As far as I am aware its not meant to change

On my l620 it doesn't even light up after cyan update...

I noticed this as well after updating to Denim. They are at full brightness. I think that before Denim they were adapting to light conditions.
