[Nexus 5X Q&A, Help & Troubleshooting] stu5797:
I am happy for you that you got a nice replacement. Another note is about calibration. I should not have to do this but if I have to that means I have to learn how to do it and spend god knows how long perfecting it. Plus, no disrespect to kernel developers but I have never used a custom kernel that didn't have some issue.
[Nexus 5X Q&A, Help & Troubleshooting] graffixnyc:
Yeah I don't flash anything custom really anymore. I use to be a crack flasher in the day. Now it's more about stability and most custom stuff does decrease stability. I at least use to root my devices but lately I haven't even done that my past few devices.
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
For those who don't want to root/flash a custom kernel, you can just use this app instead:

https://play.google.com/store/apps/details?id=com.netmanslab.sa

I simply turned Blue up +20 and it completely removed any yellow/warm hue I had. I plan to use this app until a kernel is available which allows me to make more in depth adjustments to the display coloring.
[Nexus 5X Q&A, Help & Troubleshooting] stu5797:
Nice find. Can't seem to get the screen color down perfectly. Look forward to hearing other Pepe's settings
[Nexus 5X Q&A, Help & Troubleshooting] badenglishihave:
You are 100% correct about the calibration thing. I work at a company where we are sourcing thousands of LCDs for our devices and we made it a priority to have manufacturing calibrate the screens when they are in production. It seems likely that Google accepted a certain variance in display temperature/calibration and decided to skip this step or at least not pay it very much attention.

That being said, it doesn't help those who received a screen with a yellow tint from the factory. You can't expect people to unlock, root, and flash custom kernels to fix a software problem.
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
Yeah, using this app won't make the screen 100% perfect because the values are already all set at minimum, so you can't decrease any of them. Instead, in order to eliminate the yellow tint, you are just increasing the blue hue and leaving Red and Green as they are. This helps a lot but doesn't solve the issue completely because ideally you'd actually want to decrease the red and green values from where they currently are.

This is really where having a custom kernel is going to help because it will allow you to decrease the red and green, rather than increasing the blue. It will provide a true solution to the issue at hand.

Yep, it's clear with all Nexus phones that no color calibration is done on them before being shipped out. The reason I know this is because as soon as you flash a custom kernel and go into the display color settings with the Franco Kernel app or another similar app, you see that all the color values are always set to default maximum. Which is a clear indicator that the screens have received no color calibration. And this allows people to see the slight variations in color temperatures from the screen alone.

Alternatively, when you look at color calibration on phones like the G4, M8, and other non-Nexus Android phones, it's clear that they are at least somewhat calibrated from the factory to provide a consistent color on every screen. Which is why you don't see threads of "my display is too yellow" often with those phones, like you do every time a new Nexus phone comes out.
[Nexus 5X Q&A, Help & Troubleshooting] mcantu:
phonearena has some color measurements of the Nexus 5x screen posted that show the white balance to be very accurate at 6799K. the reason no one says that the G4 or M8 or M7 are too yellow is because they are set to be very blue/cool, in the 7000-8500K range.

the color gamut of the 5x was also measured as being very accurate

(i cant post links because i'm new)
[Nexus 5X Q&A, Help & Troubleshooting] 0.0:
So the app creates a color overlay? Is it the same as how CF.lumen does it?
[Nexus 5X Q&A, Help & Troubleshooting] Jooosty:
Bought a 5X in Carbon on Craigslist. Did include a Google store receipt.

The screen is unbearably yellow.

Literally like night and day to my Z5.

Could I possibly do an RMA? Even if I wasn't the one who purchased the phone from Google. I have the receipt.

I really want to like this phone. But geesh this screen. It has the same specs as the Z5 in terms of screen but the quality just doesn't compare. However the Z5 did cost a lot more lol

We can finally now install a custom kernel and change the color calibration settings in the app kcal! Post your favorite settings here to get rid of the yellow!
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
I believe so. And a good indication for how "yellow" you screen actually is by default will be how much you need to increase the blue hue to remedy it. In my case, since my screen was not too yellow to begin with, simply increasing the Blue +10 was enough to make the whites perfectly white. I went to +20 but it was a bit too much for my eyes.

You can try but typically the RMA is tied tot he Google account that the phone was purchased with. So you are likely out of luck.

Yep! For those who are willing to flash a custom kernel, the KCal color tweaks available in yesterday's released ElementalX kernel will allow you to tweak the RGB values and easily hide any yellow the screen might have.

For reference, I made the following adjustments and my screen now looks almost exactly like my iPhone 6S screen...

Thanks so much for posting your settings! I like it! Anyone else have settings that the like
[Nexus 5X Q&A, Help & Troubleshooting] kamajikaciya:
First of all, yes it's yellow. But If you're using daylight lightbulbs in your house and you're familiar with that color, it does not bother. But if you're using white lightbulbs and you're coming from a more cold colored lcd phone you may think it's a bir warm.

RMAed with better white screen

My original 32GB carbon ordered on launch day had the yellow tinge. I also have a nexus 5.., and when compared with N5, the 5X the yellow tinge is very evident.

After about 10 days, things did not change, called google for a RMA (new replacement).

Got a replacement today (RMA). The replacement 5X screen is pure WHITE, and at par or better compared to Nexus 5. .. even the other colors look more vibrant!

The 1st 5X has a build date of 09/2015 (serial no starts with : 509KPX*)

The replacement has a build date of 10/2015 (serial no starts with : 510KPW*)

I now have to figure out how to go back to stock on the first 5X and send it back to google -- since i was rooted.

Update: Pics Here
[Nexus 5X Q&A, Help & Troubleshooting] stu5797:
That is so good to hear. I am getting my replacement today and hoping for a great one. Please let us know how going to stock is... Hope its easy
[Nexus 5X Q&A, Help & Troubleshooting] arjunprabhu:
Sure. Will do. So far, what i learnt is, flash all stock images (system, bootloader..... ).. and the very last step is to re-lock the boot-loader. Will update once done. Plan to do over the weekend, since i need to first root and transfer all my apps & data to the new 5X.

Its a shame that there is no easy way to transfer apps & data & settings in this day and age. .. The out of the box google migration does a very poor job.
[Nexus 5X Q&A, Help & Troubleshooting] bblzd:
I got a replacement for a slight gradient issue I noticed on white backgrounds (slightly darker at the bottom ). Both devices are from Oct and the new one is extremely yellow, the original is only yellow when viewed from the top and bottom angles or when compared with colder displays.

Sending back the yellowed one as the original issue is no where near as noticeable. The original looks blue in comparison even though it's warmer than my N5.
[Nexus 5X Q&A, Help & Troubleshooting] landale:
I RMA'd my first 5X as it had a loose power button and a slight yellowish to the screen, especially compared to my colleagues super white 5X screen. Sadly the replacement arrived today even more yellow than the original although at least the power button is solid. Google is going to send another one and hopefully can get this right. Hopefully third time's a charm.
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
Well, I have to say that I was wrong.

Previously, I kept saying that the yellow screen issue can be fixed by rooting, flashing a custom kernel, and adjusting the display color values. While this is true for the most part, I had an opportunity to put my phone side by side to another 5X owned by one of my clients. Even with the display color calibrations my screen still looked more yellow than his. And when I reverted my color calibration back to factory settings, my screen looked like complete garbage in comparison with his and he hasn't rooted or calibrated a thing.

It made me realize that what others have said is right. At $430 this is not something that customers should just accept. So I decided to go ahead and RMA mine as well. My replacement should be here tomorrow or Monday. If the screen is better then I'll keep the new one. If the new one is not any better then I'll just keep the current one, recalibrate the screen again and just forget about it.

Unfortunately, if the new one is as bad or worse, then I'll have a newly acquired poor taste in my mouth for Google's products.
[Nexus 5X Q&A, Help & Troubleshooting] bblzd:
Yeup I see now (after receiving a replacement that is yellow) how bad the yellow can be. The problem is most people see the non yellowed ones as "yellow" as well because it's warmer than most cold screens, but those are actually fine.
[Nexus 5X Q&A, Help & Troubleshooting] p13rr0t:
My 2nd replacement have arrived today and...screen is still yellow as f*ck.

So I assume that it is really hard to get 5x with right display, color temperature on all devices that I had, was pretty much the same.

Dunno what to do now...on one hand I really like this devices, on the other hand this yellow screen is killing me, so as the fact that I've paid 450 dollars for it.

When I was requesting my 2nd replacement, guy told me that they will escalate my case, hope someone from Google will contact me about this so I could provide feedback.

[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
I made the decision to RMA my 5X on Thursday. My new device arrived today and it looks fantastic. Side by side, it really shows how terrible the display was on my first 5X. I'm glad I took the advice of others and RMA'd it for a new one.

(New one on the left, old one on the right)

The old 5X had a 9/15 (509K) build date and the new one has a 10/15 (510K) build date.

Also, Google support is catching onto the fact that people are RMAing their devices due to the yellow tint. I ended up having to call twice. The first time the guy said that they were starting to get cases of people returning their phones for the yellow screen tint and that an RMA would not be granted because the device still functions as intended. He said that instead, his "Manager" was going to call back the following day with some other possible solutions.

I knew where that conversation was going to go so I waited an hour and called back again with a different approach. This time I told them that the device was getting very warm and shutting itself down. Knowing that they would likely try to make me go through a trouble shooting process I proactively told them that the issue continued to happen after manual reboots and even after factory resets. That was all he needed to grant an RMA instantly.

I know some will frown upon the second approach but it was clear to me that they were going to do what they could to prevent replacing a device with a clear defect. I wasn't about to waste my time getting frustrated over that.

I figured I'd share this with others planning on RMAing their phones.
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
Bought one from amazon the other day. Thought it was okay at first, as above 50% brightness the screen is a little warmer than my oneplus one which is actually ideal, but drop it down below that and wow... its yellow :( Down at 10% its horrible.

Anyone elses the same as this... as in, only really yellow at low brightness settings?

I know my oneplus one has a very blue screen, has always bothered me.... but its a mess next to it. This photos at about 25% (white balance is slightly off in shot). I've had 2 6p's before this and returned them both due to scratches and awful piss yellow screens... now the 5x too!
[Nexus 5X Q&A, Help & Troubleshooting] kamajikaciya:
Well many of the N5x and N6P owners complains from this thing: "My screen is too yellowish". And we realize it as "bad" thing. Is it true? Is it really a fault?

I'm not pretty sure about that. I'm a user of Gunnar glasses. I can feel the difference the psoitive difference between before and after. It's not a commercial or something. But it cause me thinking about this yellowish issue (!) on new nexus devices.

Here's an explanation about it: http://www.gunnars.com/how-they-work/

Maybe yellowish screen is not that bad. Our eyes did not spend enough time to evaluate for screen color. So yellowish (in fact it's warm) screens may not be a defect. Maybe they are better for our eyes.

It's just a thinking though.
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
If they'd designed it to be yellow, and all were yellow... fair enough. Its then consumer choice. There are enough pictures in this thread to indicate its actually a manufacturing problem as they're clearly inconsistent. Being *possibly* better for my eyes aside, I'll be selling this device at some point. There are not many people who will choose a phone that displays whites as yellow over one that displays whites as white.
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
Any chance you could tell me what brightness levels they were on? Assuming both the same
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
They were both turned up to 100% for the pictures.
[Nexus 5X Q&A, Help & Troubleshooting] graffixnyc:
Yeah that one looks bad. I'm happy with the replacement I had gotten. While it's a tad bit warmer than other displays I have, it's not yellow. A screen being a bit warmer than a different screen in a different device is fine with me.. But Even when I used my "yellow" tinted 5x by itself, it seemed really yellow to me and that was not having it next to a another device.

Oh and there is nothing wrong with telling a little fib to not have to jump through hoops for an exchange. I always use this one and it works because there is not much troubleshooting they can do.

"Everytime I use headphones the sound is all static, I've tried the headphones in another device and they are fine, I tried a different pair of headphones in the device and got the same result. I have done a factory reset and it hasn't fixed the issue. To me it seems like the jack is not grounded right"

They do some checking, then boom... RMA it no questions asked. I have no problems using the loop holes of a system. How I see it is these huge corporations constantly use loop holes for their gain, constantly screw over the little guy so I do not feel morally wrong for doing it..
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
Thanks for the reply! Wow, mines not that yellow full brightness. Any hint of yellow when brightness is really low? Sorry for all the questions :o
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
Yeah, the yellow tint gets worse the lower the brightness is. I already sent the bad one back to Google and have had 0 issues with the new one.
[Nexus 5X Q&A, Help & Troubleshooting] met152:
My original 5X developed a creaking on the rear. I had google send a replacement. The replacement is very yellow to the point where I'm going to keep the creaky one and return the new, yellow one. I got lucky with the screen tint on the original device.
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
So the new ones not yellow at all even low brightness, thats good to hear. Waiting on my replacement... fingers crossed.
[Nexus 5X Q&A, Help & Troubleshooting] sn0warmy:
Nope, no yellow tint as it gets dimmer. From what I've seen, the screen either has a yellow tint or it doesn't. Hopefully your new one doesn't have the same issue.
[Nexus 5X Q&A, Help & Troubleshooting] powerdoesntrun:
My original had a slightly warm display, but I was not unhappy enough with i to send it back. Then, the earpiece speaker went bad after a couple of weeks. The replacement I received was even more yellow than the first, so I am sending it back, too. I had to go through exactly two RMAs for both my Nexus 4 and Nexus 7 due to early manufacturing defects, and each time, the third was fine. Hoping that trend continues because if not, I may have to jump ship.
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
Well, replacements here... you can see the difference (both at about 25% brightness here)! Its still definitely warmer than the oneplus one's screen and to my eye has a slight bit of yellow, but its MUCH better. Time to root and sort the DPI out! :)
[Nexus 5X Q&A, Help & Troubleshooting] powerdoesntrun:
I received my replacement and it is less yellow that the last one, but still warm. In fact, if you look at it from above or below at an angle, it looks downright green. My previous one did not do this. I'm definitely not seeing the drastic improvement others have seen, and nothing that looks remotely as cool or neutral as my Nexus 4 or, say, my MacBook screen.

Definitely seems like they used low-quality panels to cut costs. Seems to be the Nexus way. Put a better camera in, but use a worse panel.

Oh, well. It's probably better for my eyes and sleep anyway.
[Nexus 5X Q&A, Help & Troubleshooting] Confused_Cheese:
A work colleague has a 5x and we compared screens. Mine is still a little yellow in comparison, but his screen, to my eye at least, is a little pink. Above 30-40% the yellow tint is hardly noticeable. Drop it down to 10% and its quite visible. Its still better than my last by quite a margin but my oneplus one is cooler at any brightness... too cool in places. Compared to the missus's iPhone 6, its warmer but it makes her screen look really grey and dull.

Not sure its worth me playing the RMA roulette again. I've returned 2 6p's and one 5x so far. Current batch of nexus phones seem to have poor build issues :( Worst of all, instead of refunding me for my 6p, they refunded a nexus 5 order from 2 years ago! I'm still £150 down now and trying to get customer services to give me back my damn money.
[Nexus 5X Q&A, Help & Troubleshooting] bblzd:
The panel itself is top notch. Anandtech showed it to be one of the best IPS panels in a phone to date.

Notice how the 5x is the closest to 6500k white point level? Technically the 5x has the perfect colour temperature, and most other devices will either be more yellow or more blue.

Unfortunately the issue seems to be with LG's quality control. So the panel is great but many seem to be going out miscalibrated, probably LG trying to cut corners and save a few bucks on a low margin device.
[Nexus 5X Q&A, Help & Troubleshooting] Xentar712:
I came across this thread because of the brightness and not the color issue but has anybody actually used a colorimeter to measure their screens? I did and only got a max brightness of 400 nits. I was hoping for the 480 Anandtech got but I can't seem to get it.

Also, just to throw my two cents in about the yellow screen issue. I too also have a more yellow screen than any other smartphone I have owned but that's actually the color white you want to aim for if you want the most natural looking colors. We're just used to the cooler whites and over saturated colors that have been handed to us in almost every other display. When I calibrate my monitors at home, I aim for 6500K and the whites look almost the same as what I have on this phone. I measured the whites on my phone and got 6200K, which is really good in my opinion. In comparison, my Z3 compact measures 9600K. The funny thing is Z3 "looks" brighter but it's actually also 400 nits. The colors are also more saturated so the colors pop out more. Yes, the 5X looks more bland and dimmer in comparison, but it's way more realistic when looking at the pictures I just took.

Personal preference I guess, but I'm happy with the calibration they did on these. It's weird that there are others that have a higher white point though. If you can see the difference in a picture, it's a matter of 2000K difference I bet. I just don't understand how they let screens so differently calibrated get released.

At first I thought it was too yellow but now it looks great to my eyes and all my other devices look waaaayyyy too blue. I calibrated my monitors and laptop to match the 5x haha.
[Nexus 5X Q&A, Help & Troubleshooting] bblzd:
It should be different from the Nexus 4 which was very blue.

Nexus 4 is 8500k colour temperature, that's about as cold (blue) as it could possibly get.

The Nexus 5x is right around 6500k which is perfect colour temperature (not too warm, not too cold). It will appear yellow in comparison to a blue screen such as the Nexus 4 and most other LCDs which tend to be on the cooler side.

I'd say you probably have a proper 5x display then. The extremely yellow 5x displays are very obviously yellow even when not compared to another screen.
