Bought my 6 Plus about 20 days ago. Everything is perfect cosmetically and functionally and the screen uniformity is 100%. I downloaded the dead pixel spotter app the other day and noticed that I have a dead pixel near the center of my screen on two colours (red and green). It's not terribly noticeable but now I notice it if I look for it depending on the image on my screen. Should I go to apple and ask for a screen replacement or am I asking for trouble?
