Hi. Just noticed that there's a permanent lit (white) pixel showing dead centre of my screen. Fair enough, it only shows on dark areas but is it unreasonable to expect the screen to be perfect? I had a galaxy 10.1 previously, well two actually, but had to return them both because they each had two or more dead pixels. Now this. What would you do? I'm still well within the return timescale but would the replacement be any better? Thanks.
