My screen is not brighter. I do however have signal issues
Is your signal issue fixed?

ICS has a gradient to it, yes? In other words, if you look at Status or any Settings page, for example, it lightens up at the bottom of the page, right? I can't remember if the last Gnex looked the same...

You can download an app called Screen Test and it will give you many different colors and whatnot to see if there is actually a difference in brightness at the bottom, but I think it's unlikely.
Usually if there is a variance in brightness it will be a specific spot, not a whole section like the bottom. This is due to amoled technology being 'grown' and not built. They sometimes have some variances due to being an organic material.
