Im not sure if this is an issue in 4.1 or not but the background picture at the bottom is darker if you use it as a wallpaper but when viewing it normally its the same brightness, is there a fix to this?
It is to draw emphasis to the dock - i think
Edit: i personally don't know how to fix it on the phone it self, i'd assume you'd just have to edit the photo on your computer to make the bottom lighter so it looks normal as wallpaper
