[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Here's the thing though: I went through this with a number of devices, and it's not as simple as you imply here. I'll use my iPad 3 as an example so I can't be accused of picking on any Android vendor.

I bought one of the first iPad 3s, because I wanted a high-resolution screen for text. I love nice, sharp text. I took it to work, and just happened to sit down with a coworker who had also recently purchased one. The screen on mine was _yellowish_, not simply warmer. Grays weren't actually gray, they were a yellowish-gray. Whites looked like they were floating in urine. Colors were washed out (likely because there was too much yellow in them). Contrast in UI elements, like in OS 6 Settings, was vastly decreased, to the point where it was almost hard to make out some fields against the background. His was the opposite of all of this--whites looked white (not blue, turns out even a "good" iPad 3 screen is still pretty warm), grays were a nice, sharp gray, contrast was excellent throughout the UI, and colors were gorgeous.

I ended up buying a good one, which was immediately apparent as I held it side-by-side to my first one. And even as I used it by itself, I understood why I was a little disappointed in the screen of the first one from the moment I fired it up.

I went through this with ASUS TF201s (God, those things were hot messes all around), Nexus 10s, and Nexus 7s. I think it's something common to how these screens are manufactured, and I'm not 100% convinced that it's simply color temp. If it _is_ just color temp, then the UIs we're using aren't very well suited for warmer colors--the biggest problem I have with the issue is that there's so much less contrast between, say, the browser address bar and the gray background, and between text and what's supposed to be a white background.

Toss in the fact that there's obviously significant variability between devices, and it can't simply be how the screens are purposefully calibrated. What, are the ones that people perceive as having whiter screens the defective units? Sorry, with so much variability, it can't be on purpose. And again, I saw this with a number of different devices, side-by-side, and made sure to ask other peoples' opinions to make sure it wasn't just me. Everyone I asked agreed that the "yellowish" screens were unattractive, washed out, and basically looked like they had a layer of urine underneath the glass.

Maybe some folks have never had two devices to hold side-by-side and thus haven't seen the difference. Maybe some folks have been lucky enough to nothing but non-yellowish screens, and so have never seen the problem. But it's there, and the yellowish tint really detracts from the experience. And I find it interesting that some reviewers say the screen is excellent with nice bright colors, and others say the screen is a bit washed out--perhaps the screen variability accounts for some of the inconsistency in reviews?

I think you're being facetious that there's no issue, right? Because certainly, your pictures illustrate how the contrast is affected, not just the whites. Look at the address bar in the browser--it's too bad that you didn't show the address bar on all of the devices, because then you'd see how much less contrast there is between the address bar and the background. Both are a bit yellowish, rather than being white on gray and they're supposed to be.

I think these images are the best I've seen so far at illustrating the problem. I just can't see how someone could say the Nexus 5 here is a pleasant screen to look at.
