Hello, received my galaxy nexus recently and overall pretty pleased with it except for the color representation of the screen. Whenever I'm on a light colored background I'll notice and band of a darker shade running up the near middle of the screen and also across horizontally. The effect is diminished if brightness is increased but still noticeable under certain conditions. I purchased this through verizon online on the launch day and just wondering what my options are. Could I exchange for another model in a store or have to do online if at all possible and what are the fees I may incur? Thanks.
