bought my 128gb 6S just this past July. I have babied this phone. It's immaculate. I did just barely notice, however, the top edge had a bit of a dark "fade" in the title bar area, and there appears to be one dead pixel in the middle of the signal dots/bars. Those of you who have replaced things under warranty, do you think it's worth the trouble? Do you think they'd do anything about it, since it isn't very prominent?
