Question regarding screen retention. Do you guys see any retention when switching between dark and brighter screens? e.g when in the google play store: you see the tiles of the application categories, when I switch between the categories music, movies etc. you have the grey background screen for a second and I can clearly see the borders from the category tiles. When I open XDA developers I see the launcher icon contours on the brownish background of the start screen. I had several AMOLED screens (Nexus One, Nexus S and GSII) and have never seen so slow reacting LEDs. I will get tomorrow my replacement but I am afraid that this will be normal.
