I got my Paperwhite at Best Buy and noticed right away that about the lower 2/3 of the screen had a pinkish hue. I contacted Amazon chat support and they sent me a new one right away with overnight shipping! I opened it and I think it might be better, but in a sense worse. The pink spot is a lot smaller, but my current one is more uniform so it's not as distracting. I know this is really common and I knew it going in, but I just had to see for myself, hah! It's a shame too because I actually like it (besides the spots).
I took a couple pictures.
The first one is actually surprising. The light for both is completely at the lowest setting but one is clearly more bright than the other.
This next picture shows the spots a lot better. The one on the right (in both pics) is my current one. The one on the left is the replacement from Amazon. The pink spot on the one on the right is a lot more visible in person. The one Amazon sent me also seems a lot more....white I guess you could say.
I just need to decide if I should keep getting replacements, if my first one is good enough or if I should return them without a replacement. Seems like the common question around here!
