Thanks for that info. I just wanted to make sure I could rule out whether it is coming from a specific factory or not. And it is also certain that it doesnt matter what model you get, 16 or 64GB, the culprit is the Pentile Matrix screens used in these devices. There are some who get lucky with less tint and some unlucky people get annoying tint, black spots, and whatever other display issues that have come up in this op. Unfortunately, getting a replacement is like taking a gamble on whether your replaced device will be better or worse.
