E90, still not right

I should have known this, my E90 which just got back from service is having still problems.

I just noticed that small screen brightness is all time full and setting for brightness is not affecting at all. Great. Oh why Nokia why, can you please explain to me what is difference between E90 and other great phones you are producing (like E61i) ?

Now I have my E90 with full brightness, it's not the show stopper but annoying feature.
