[Nexus 5 Q&A, Help & Troubleshooting] cliffspab:
Based on me putting two N5's side by side and everyone in the room agreeing my screen looked very yellow and his looked very white.

Whether you like a yellow screen or not, a distinct, tangible difference between displays on the same model indicates that something is up.

I know you're determined to imply that people in this thread with complaints are stupid plebs, but that really isnt the case.
[Nexus 5 Q&A, Help & Troubleshooting] Vincent Law:
We already went over this. Bad panels happen. It doesn't mean there's some panel epidemic. Did you hear about all those iPad 3 devices being returned for bad displays like wynand32's? No? Of course not, because a handful of bad panels is not an epidemic or a sign of a production issue. Furthermore, just because you may have a bad panel, does not mean everyone else in this thread with "yellow" displays are bad panels. For all you know, other people in this thread have panels that look like your good Nexus 5. You have no idea, you can't make any claims to know, so why even toy with the idea?

Those are your words, not mine. I'm trying to be informative instead of speculative.
[Nexus 5 Q&A, Help & Troubleshooting] eep2378:
I agree. If we're talking about the most accurate color reproduction then it will tend to be warmer. The problem is most people's perception of what is "accurate" is, simply wrong. If you've ever seen an ISF calibrated monitor/display you can clearly see how warm the colors are.
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Actually, this WAS an issue when the iPad 3 was first released. It was all over Apple forums, just like this issue is all over this forum. And the Nexus 10 had it, and the Nexus 7 had it, and the ASUS TF201 had it, and etc., etc., to varying degrees.

It might simply be that this is growing pains for the manufacturing process and eventually things stabilize. Nevertheless, it doesn't detract from the fact that there's an issue right now where quite a few people (here and on other forums) are experiencing devices with yellowish screens.

I don't think anyone is making this into more of an issue than it is--it's precisely what it is, namely that some people have unpleasant screens and they come to forums like this to see if their issue is isolated or not. I think we have enough instances to indicate a problem, and for those of us who have it, whether or not it's "epidemic" is irrelevant.
[Nexus 5 Q&A, Help & Troubleshooting] Vincent Law:
Yes, it was all over, in the news, everything. Bad panels everywhere. I mean, really, come on.

So far, based on what I've read, we have exactly one confirmed instance. One. Please feel free to correct me if you've managed to find any other actually confirmed instances of yellow screens, instead of people comparing their phones to others and wondering why the color temperature is warmer.
[Nexus 5 Q&A, Help & Troubleshooting] cliffspab:
You suggested I was looking at photos. I've clarified that I wasn't.

I haven't suggested there's an epidemic, either. Only that in some cases panels are clearly off white.
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Dude, you come on.

http://www.zdnet.com/blog/hardware/some-new-ipad-retina-displays-marred-by-yellowish-hue/19199

http://www.gottabemobile.com/2012/03/26/new-ipad-yellow/

There, two news story about the iPad 3 that I found in about 20 seconds. Do a freaking Google search on "iPad 3 yellow screen" and then come back and tell me it wasn't an issue.

Again, those of us who have the issue are merely pointing it out and trying to find others who have it. And there are at least a few people here who have more than one N5 to compare against the other, and they've noted the variation. I'm sure that this early in the process there aren't that many people who ordered multiple units and so naturally have them to compare, and so the presence of even a few is significant.

In short, we're not the ones making a federal case out of this. And you would think that noting a potential issue would be a _good_ thing, so that Google and LG could perhaps be informed and resolve it. Why's it such an issue to you that we're pointing it out?
[Nexus 5 Q&A, Help & Troubleshooting] Vincent Law:
Why is it such an issue to you that not everyone shares the same problem as you? The only irritating thing is when people claim there's a problem, it snowballs, people start RMA'ing their phones for no discernable reason, and pass around completely incorrect information. Prior to my entrance into this thread, any mention of color temperature was shot down and dismissed entirely, despite the fact that it is the most likely explanation for the vast majority of people.

I prefer that people are informed of ALL the possibilities, not made to assume that the most dramatic one is the answer.

BTW, I don't understand your point with those google searches. Of course you'll find some random people complaining about displays. Panels are defective in any model. And considering the iPad had a much, much larger userbase, it only stands to reason that finding people complaining about it would be more common. It isn't indicative of anything at all. Not to mention, the iPad suffered from a non-panel-related issue (adhesive, where the center would be white and the edges would not). Read your own source. Or just disregard this entirely because it's not at all helpful to this discussion.
[Nexus 5 Q&A, Help & Troubleshooting] eksasol:
Looks like we have too many new Nexus users.

I have used Nexus phones since the beginning, Google have always purposefully calibrated their devices to a warmer tone. If you compared the Nexus S or Galaxy Nexus with it's counterpart non-Nexus variants (Galaxy S & S2), the Nexus is always warmer. Same thing with the Nexus 7. With my N4 its not really a problem since it wasn't so warm as before (except the for the bad gamma this time).

If it's true about the glue needing time to dry, then just wait it out and use CyanogenMod or Faux kernel, you will be able to switch between Google's color settings and other settings (using your choice of kernel apps) or set your own.

I do agree this one looks abnormal.
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
First, read both stories. The first source made an assumption about the glue, the second noted that it's not necessarily an issue with the glue (which wouldn't tend to cover the entire screen). It's precisely the same issue as we're discussing here: variations in screen colors where some are more yellowish with less contrast and washed out colors, and some are more white with higher contrast and more vibrant colors. This was exactly what I experienced with my iPad 3, and I'm here to testify that a good iPad 3 screen is a glorious thing while the yellowish screens were very disappointing.

Again, the issue is being noted and discussed. You're the one making it into such a fervent debate. And you've really made the point yourself where you say "Panels are defective in any model." That's all we're saying here--that some of us have panels that seem defective, and we're trying to determine how widespread the issue is so we know how to proceed.

Again, read the second story, look at the posted images, and read the commentary. It's exactly what we're discussing here.

One with a perfect screen, one with a rattle free power button

Hi,

I also got 2 Nexus 5 this week. One has a perfect screen and a rattling power button, the other one has a really yellow-ish screen with no other problems at all.

I really like the feel of the Nexus, but I'll send them back and wait for the next charge.

See attachment for more details.

Best wishes!
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Thanks for posting that pic. It might be the best one so far at showing the variation.

So, since we now have at least a few examples of side-by-side comparisons (and there are others in other threads on this forum and elsewhere), I think that regardless of which one is considered to be "correct" (warmer and yellowish or colder and whiter), there's clearly variability in the screens.

Personally, I see the yellowish version as being less pleasant, with less contrast and less vibrant colors. Perhaps others prefer this. But there's no doubt that there's room for folks to be concerned about which screen they receive.

Edit: In looking at the images again, I think there might be a brightness difference in the screens as well. However, to me, it's clear that the contrast between the address field on the yellowish version and the "gray" background (which is more yellowish) is significantly less pronounced than on the whiter version, where the gray is... well... more gray and thus the white stands out more.

---------- Post added at 12:25 PM ---------- Previous post was at 11:55 AM ----------

I also wanted to refer back to this Eizo page that I posted earlier (or in another thread, can't remember). http://www.eizo.com/global/library/basics/color_temperature_on_an_LCD_monitor/

In looking at this image, I submit that the N5s with yellowish screens are much closer to the 5000K example on the left than the 6500K example in the middle:

In this image, you can see how all colors, including grays, are shifted toward yellow on the 5000K example, while they remain more true and vibrant (in particular grays) in the 6500K example. I think this is the same as we're seeing on the N5s, where there's less contrast between the grays and whites in the UI (which is important, because this is common throughout the KitKat design scheme):

This does support the notion that it's indeed color temp involved here (which I'd admittedly questioned). But it also tends to support the idea that these screens are NOT uniformly calibrated to 6500K, which some have asserted is the optimal. If it is indeed simply color temp that's involved here, and not a pure manufacturing defect, then we can say that some screens are simply too warm. I'd submit that such variation is unacceptable.
[Nexus 5 Q&A, Help & Troubleshooting] ptscon:
Are the phones identical otherwise?

---------- Post added at 10:11 PM ---------- Previous post was at 10:05 PM ----------

How about using something physical as a reference point when posting pictures of the screens?

Take the user manual that came with the phone, flip open a page, put it next to the phone with a white background.

That way we can have a real reference point to compare to.
[Nexus 5 Q&A, Help & Troubleshooting] geoldr:
I have a Nexus 5 with dead pixels. Today I got the new one in, and I compared them side by side - the new one has no dead pixels but a yellowish screen just like the post on page 6.

I won't be returning it because it doesn't bother me, and I figure eventually there will be some kind of fix for this. I like the warmer screen,
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
You got a replacement already? Wow, that was fast.
[Nexus 5 Q&A, Help & Troubleshooting] geoldr:
I got my phone on Monday, called in Tuesday, they shipped it out same day and it came in on Thursday but I picked it up from UPS today.

Also the vibrator motor on the new one is kinda annoying, when you type a lot the motor likes gets stronger and louder whereas on my original it always stayed the same.

---------- Post added at 02:42 PM ---------- Previous post was at 02:16 PM ----------

But we should be expecting some kernel modules or some apps to help adjust the screen right? The Nexus 4 had it, my older Galaxy S3 had it, so I am sure it's possible to fix with some updates.
[Nexus 5 Q&A, Help & Troubleshooting] shilent:
Wouldn't the color of the manual be different depending on the room lighting?

Congrats on that, but yeesh, my replacement order from 11/4 is showing a shipping date of 11/26.
[Nexus 5 Q&A, Help & Troubleshooting] geoldr:
Mine said it would ship 2-3 weeks, but shipped out same day. That's weird.

I have the 32gb White version.
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Yeah. Maybe the rep saw one sitting next to him/her and decided to grab it or something. Otherwise, just good luck. Like winning the lottery. :laugh:
[Nexus 5 Q&A, Help & Troubleshooting] geoldr:
Haha, one strange lottery.

No dead pixels, but now a crappy vibration motor and a yellow screen. Ah idk what to do. I don't think I want to return it again.

[Nexus 5 Q&A, Help & Troubleshooting] got_killed:
Had to RMA my 16GB White. Went to a Sprint corp store and there was another N5 and an LG G2 up for display. I open the calender, gmail, and play store and theres a noticable warm tint on mine.
[Nexus 5 Q&A, Help & Troubleshooting] sciguy125:
To get some objective data, I pulled out my colorimeter (hardware to calibrate monitors).

Nexus 5 (16GB black) - 5672K

Galaxy S2 (i777) - 6286K

The above color temperatures are for full brightness. I tried different brightnesses, and they were fairly consistent.

"White" differs depending on who you talk to. But most photographers (like me) calibrate their monitors to 6500K, whereas graphic designers tend to use 5000K. The "daylight" bulb in the lamp next to me says it's 5000K.
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
So, pretty warm. Given the apparent variability in screens, though, we don't really know how yours compares to others. Hypothetically, yours could be on the cool side for N5s.
[Nexus 5 Q&A, Help & Troubleshooting] Chad_Petree:
The Optimus F6 calibration is totally ****ed up, it's incredibly blue, looks like amoled actually :eek: , the iphone 4s screen looks perfect to me, a little warm, but not overly warm like the nexus 5, damn I thought I was gonna keep my yellowish/warm nexus 5 but after looking at the comparison I'm not so sure anymore

:crying::crying:

http://xdaforums.com/attachment.php?attachmentid=2380004&d=138394020

I can't tell if the screen on the right it's actually a better screen it kinda looks too blue :crying:
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Agreed about the iPhone being the best of the three, but the image's poster didn't see the N5 as a problem so maybe those pictures are deceiving (or from the later shots where the N5 screen looks more neutral, maybe it's affected by screen angle; who knows?). What I can say about the two N5s is that the one on the right has better grays with more contrast.

But most important, all of this highlights the amount of variation--let's say the one N5 _is_ a little _too_ cold. Okay, fine, that's possible. But man, with the other examples given that just means N5 screens are all over the place. It was noted in another thread that these screens aren't actually made by LG (while the LG G2 _is_ using LG's screens), and so what I think we have here is a manufacturer that is being very inconsistent in their quality control. This is likely one way that LG has cut costs to squeeze the N5 in at $349/$399, by going with the cheapest display bidder.

I'm seriously considering getting a G2 to try out. I much prefer having a Nexus, but if my replacement N5 has the same yellow tint, I don't know that I want to play the game of replacing until I get one that I like. Even if it's not a "problem," as some have implied (and with which I disagree), I simply don't want that warm of a screen--it ruins the experience for me, with the screen looking like it's being filtered through a layer of urine when I switch from using my Nexus 10 to my N5. I'd rather have an excellent screen along with everything else the N5 has, and give up stock Android.

Hell, my N5 has other issues that bug me. Data connectivity is flaky--mine can't decide if it wants to be on HSPA+ or LTE, outside in clear spaces. Inside my office, I get a weaker signal than with my N4--there, it gains and loses bars as it sits there, flips from EDGE to HSPA+ to LTE to no signal. So I might simply have bad radios as well. And battery life, probably because the radios are constantly hunting for a good connection, has been much less than stellar. I can't make it through a workday on a single charge, and my screen on time has typically been less than 2 hours.

Okay, sorry for the mini-rant. I'm just a bit disappointed.
[Nexus 5 Q&A, Help & Troubleshooting] PhilipL:
Hi

If you take a screen crap than measure the colour on the white browser page then:

Nexus 5 is RGB values of approx 220, 232, 253

Nexus 4 is RGB values of approx 208, 221, 253

Assuming the camera is set up to capture the same values then the Nexus 5 is actually the truer to white and better calibrated. The Nexus 4 is very blue on that clip (has lower values of Red and Green.)

Typically, we are taught to believe a bluer white is a whiter white, this is true from washing powder to copier paper which often have blue dies added, and even teeth and the Hollywood smile is a very cold white!

Comparing the Nexus 5 to the Nexus 4 here, then yes the Nexus 5 is warmer, but actually the whites are closer to true white. If I compare white on the Nexus 5 to my calibrated monitor at 6500K, it is much closer than the Nexus 4 which is very cold (towards blue).

Unless there is something wrong with your phone, it is probably the better calibrated when comparing to the Nexus 4. I thought I read somewhere that Google were taking great care with calibrating the LCDs in the Nexus 5 and they were calibrated twice, once by the manufacturer, then again the phone is tested and adjusted.

Edit: Okay those examples of those Nexus 5s show completely different calibrations of screen. That's not good.

Regards

Phil
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Exactly. That's been my point throughout this thread--that there's _significant_ variation between N5s, and that some are much warmer than others. I pointed out the video just to show that the N5 in it is warmer (whether it's the "right" warmth or not can't really be seen from the video, or from pics, unless everything else has been corrected for).

As I look at mine, it's simply too warm, to the point where everything is shifted yellow including the grays (very important because the UI is now so light-themed). That washes out colors in general, reduces contrast, and makes the experience far less pleasant.

Sure, some screens are _too_ cold and whites are bluish. But even then, grays tend to be more true and contrast remains sufficient to make the UI attractive. It can't be stressed enough: on the really yellowish N5 screens, it's like they've been dipped in urine. Everything's a dingy yellow, and I just can't see how that's supposed to be acceptable.
[Nexus 5 Q&A, Help & Troubleshooting] myorks1127:
For everyone that is whining about the screen (it's actually amazing) I have a simple fix to your dilemma, get a different phone! Wow that was such a hard idea to come up with lmao...
[Nexus 5 Q&A, Help & Troubleshooting] wynand32:
Oh my god, you're right! Holy cow, why didn't I think of that?!?

Seriously, why do people post things like this? It will always be a mystery to me. Did it ever occur to this person that maybe his screen is great, while ours isn't? That indeed that's the entire point of this thread? And shouldn't issues be reported/discussed so that they can be brought to the attention of Google/LG and maybe resolved? Sure, we could all just assume that every N5 screen is like ours and get different phones, but then it's entirely possible that we'd be missing out on an otherwise excellent device.

Of course I can get a different phone--that's obvious. But perhaps I like the N5 in general, and would simply like one with a better screen than the one I have (and, better radios/antenna, but that's a different topic).

Most important, why does this person care that this thread exists, and that we're discussing something we don't like about our N5s? I mean, if his solution to our displeasure over our screens is to get different phones, shouldn't his own displeasure at reading our complaints be to simply ignore this thread? Does it make him question his purchase of the phone, create a little cognitive dissonance, or does he believe that our displeasure reflects somehow on his decision? Does he feel like we're insulting his phone by saying we don't like ours?

I will really never understand why people respond this way to complaints on forums. Don't agree? Don't have this problem? Fine, ignore the thread. It costs you nothing. Or, certainly, report in that your phone is fine, and contribute something of value--that would help compile evidence as to how widespread the issue is. Maybe we're just outliers, and most N5s are perfect. If so, wonderful! That means we can have some confidence that a replacement will resolve our issue.

But to attack us like this? Does this person have nothing better to do with his time?

I'm not that happy with the screen either. My HTC One screen was flawless and dare I say perfect. My Nexus is washed out and dull. Between that and the speaker I think I'm getting the G2 instead.
[Nexus 5 Q&A, Help & Troubleshooting] ohmimpotence:
Max brightness on N7 and N5, the N5 appears to be more washed out and yellow. More pics here

It's my wife's though and she doesn't seem that bothered by it. Like posts have explained here, she's aware it's more natural than the blue screens. I should have gotten some pictures of it next to my iPod Touch 4G too but it's pretty much the same as the comparison to the 4S in this post, I would have preferred a color closer to that.
[Nexus 5 Q&A, Help & Troubleshooting] nadrojcote:
I find the screen on mine to be perfect, but I prefer a calibrated screen, which I believe the n5 is. HTC and Samsung add blue to the white to make it seem brighter. The white you think you're seeing on those phones is not a real white.

My nexus 5 is warm, and i have the opportunity to see a cold from a friend. In the real life is different than in photos. The nexus 5 cold looks too blue.

I install display tester in both phones and all colours looks exactly the same except white and grey in the two nexus, a big surprise to me (and strange).

And the result: My nexus 5 warm and it´s withes are more or less like in the plasma.

So if you are going to RMA the warm nexus 5, you are returning the right calibration nexus, because the cold nexus is the one who has bad calibration.:good:
