hi guys my screen i think it's has yellow tint took pictures with my laptop
[Nexus 6P Q&A, Help & Troubleshooting] hanano17:
Looks pinkish to me.
[Nexus 6P Q&A, Help & Troubleshooting] Gizmoe:
Yeah looks pink to me too. Samsung's displays are known to be a little pink and/or yellow. You will stop noticing it once you stop thinking about it. My first Samsung screen made me uneasy too but I have had many since and they all have the same traits.
[Nexus 6P Q&A, Help & Troubleshooting] wahibmichael:
i don't understand why google don't make a setting in the developer option where we can set the display color temperature & white point instead of this RMA process, I guess everyone will be happy.
[Nexus 6P Q&A, Help & Troubleshooting] iduser4:
I just got my 6p today and like some of you guys it had a yellow tint. I'm assuming that the way to fix it as best as possible is to have elementalX or a white balance switcher. Also this is my first amoled phone is there a way to hide the nav and status bar to prevent burn-in?
[Nexus 6P Q&A, Help & Troubleshooting] bennyboy_84:
I know this thread is getting old now but I wanted to update it as the problem is not yet resolved as of January 13th 2016. I had bought a 6P around launch, and had returned it right away as the screen on it was HORRIBLY yellow. I waited 2 months for the initial batches to go out and ordered again Jan 6th, received 2 days later. Display was MUCH whiter but unfortunately had intense speaker imbalance but most importantly a green "blob" at the bottom right corner and a pink one top left. It is very visible (not really on the pictures though) and very annoying on white or light grey screens so I RMA'd it.

Now, received my (3rd) unit : back to yellow town. Speakers are OK though this time. Here are 2 pictures comparing the 2 phones (Yellow, 3rd unit on left and white, 2nd unit on the right).

Interstingly enough, both are 32 GB Graphite manufactured on the same day (Nov 14th). When taking pictures from my One M8 of both phones, you can actually see a weird "old CRT screen refresh" effect on both phones but that is much more pronounced on the yellow unit, like the yellow one has a different (faster?) refresh rate than the white one? Not sure it's relevant but anyway.

Also, the yellow unit has an intense shifting of colors even at a small angle (4-5 degrees is enough to see a drastic change) whereas the whiter one is pretty even unless I have it at a 60-70 degrees angle (then rainbow effect for both units). The yellow unit actually looks way better if I hold it at a 10 degrees angle (looks like actual white).

In any case, I believe I'll give it another shot and RMA again as the yellowness, although lighter than on my first Oct 2015 unit, is ANNOYING as hell to me. If the 4th one isin't better ; that's it for me, I'll grab a Z5 or other LCD phone.

P.S. : Agree with wahibmichael. Would it kill Google to add White Balance correction in the display settings menu as Sony does on their Z line? Urgh.
[Nexus 6P Q&A, Help & Troubleshooting] BTT8:
Did they give you a new device?
[Nexus 6P Q&A, Help & Troubleshooting] bennyboy_84:
It will be shipping tomorrow, yes. I specifically told the support guy to please pick a phone from a different (later) lot and he told me that he will put a note to that effect that it's not a problem. I have absolutely 0 complaints about the Google customer service up to this day, every time I've chatted or called them it's been a flawless experience. I even told the guy I wouldn't mind if somebody opened the box, booted the device and looked at a white screen before shipping it (which is the truth tbh and is likely a step that is lacking at Huawei). Don't expect them to do that but hey, figured I'd put it in the chat log and maybe the message will go higher up. Or not.

Will update with new device results when I get it early next week I assume. In the meantime, a lovely picture of my current N6P next to an Xperia Z3 both at full brightness. I'm just so sad and tired at this point. Of course the Xperia Z3 is an LCD, much brighter and colder screen than the N6P's amoled but still.

http://i65.tinypic.com/fypllg.jpg

Update : Received the new unit, which, OF COURSE, is the exact same manufacturing date as the previous 2 devices, November 14th. This is so stupid the guy specifically said he would put a note so that they take the unit from a different batch, I should have known better. The screen is a tadbit yellower than the last unit I got but now the speakers are out of balance. Previous unit did not have this. I will keep the previous device with balanced speaker and return this device and just give up. I assume that's what Google wants to happen : well they've won. This phone is yellow.
[Nexus 6P Q&A, Help & Troubleshooting] d.badgio:
Apologies if this has already been discussed...

Just got my Nexus 6p and the yellow tint to the screen was the first thing I noticed along with the fact the top was louder than the bottom. After comparing the screen to Samsung flagships I noticed the whites appeared to have a bluer tint which I much preferred.

I googled both issues and came across a YouTuber by the name of HaxorTech, who suggests downloading an app by the name of 'Screen adjust' from the Play store. I've got to say with the blues turned up to ten this app works well and in the video he says he has seen no noticeable affect on battery life but I still have my reservations about the app and it would be great to hear what you guys think.

I'm guessing this app merely puts a filter over the screen rather than changing the actual screen settings which seems like a bit of a bodge and I'd like to check benchmarks before and after installation (shouldn't be difference). Also as this is an unrated app with various permissions including location and phone is the app 'safe'?

Any advice on how to go about this?? :)

Look at Heisenbergs tutorial, it will guide you through everything. (I recommend PureNexus rom and ElementalX kernel.)
[Nexus 6P Q&A, Help & Troubleshooting] Riardon:
My 6P has a yellow tint on the lower part of the screen. This is my 2nd Nexus 6P as I returned my 1st due to loose rattling button and unbalanced speakers and sound output from the 3.5mm jack was too low.. Do they quality check these phones ? Quality seems rather poor to me if I judge it from my experience. What annoys me is that the tint is uneven. Appears only on the lower part of the screen.

[Nexus 6P Q&A, Help & Troubleshooting] ahmed534:
Just install this app from play store and set blue tint to 8 value

This Works

Wow this has worked for me. When I first saw the screen I was like am I crazy this looks yellow but found many online complaints as well. Wondered if I need to return the device but using this +11 for me fixes it so I’m assuming it’s a software issue. When looking straight on however screen appears white without the software. It’s when you bend and look at angles it becomes yellowish.
[Nexus 6P Q&A, Help & Troubleshooting] yossi2010:
Android N added a screen calibration menu but sadly there is no sensor calibration menu. my screen is fine though...

I can't believe that i am going to RMA a perfectly fine nexus device just because a 0.1 rads/sec gyro offset fu**s up every compass and vr app on the planet...

I will RMA it if a factory reset does nothing to recalibrate it.
[Nexus 6P Q&A, Help & Troubleshooting] triplettt:
How did you even find out about this defect???? Most people wouldnt know how to test for it so maybe you can help us figure out how to test for it?
[Nexus 6P Q&A, Help & Troubleshooting] Gizmoe:
Open maps and tap the location icon. If it's off it should make you do three series of specific movements to re-calibrate. Mine does it every time I wipe it. If it's on the hardware level then you just got unlucky. That's not even an issue I've read anywhere with this device.
[Nexus 6P Q&A, Help & Troubleshooting] Cloudane:
Didn't - but suddenly it has gone "warm" when viewed face-on. Normal if laid on a table and viewed at an angle. Optical illusion? Since kind of "night shift" mode I don't know about?

Maybe it was my imagination. When you look at something with a lower colour temp for a while (which seems to shift with viewing angle on this screen, oddly) the higher one seems really yellow until you get used to it again. Then the cooler one looks too blue after a while of looking at that
[Nexus 6P Q&A, Help & Troubleshooting] yossi2010:
Just lay the phone on the table and see what the GYRO says.

Ii use an app called "sensor kinetics" to see the values.

if it's something like 0.15(+- 0.05) when the phone is static it's bad if its revolving about the 0 and says 0.01 or 0.002 it is fine ^^

You could also look at the rotational sensor(it is the gyro but integrated into an orientation sensor) I had a constantly elevating graph(like a slope) which means the phone thinks it's always spinning and thus rendering VR and compass apps that uses the gyro(aka 99% of them) useless.

After replacing the motherboard the rotation sensor stays constant when the phone is static and the gyro gives values near 0.

Sent the device to huawei israel and they replaced the motherboard.

The gyro works great and the compass is perfectly aligned most of the time.

color changer pro or kernel auditor for better whites

Yeah the screen does have slight yellowish tint, but you can handle this by either using a root app color change pro https://play.google.com/store/apps/details?id=mobi.omegacentauri.red_pro&hl=en, or you can change the screen RGB values using kernel auditor https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=en.

RGB values that worked fine for me on kernel auditor were

R 195

G 205

B 255

Saturation - 40

Screen Value 132

screen contrast 132

Give it a try, i love the screen after these settings, the whites are much better and also kernel auditor has an option to get high brightness mode, its makes the screen much more visible under direct sunlight. :D

#makenexusgreatagain :p:p
[Nexus 6P Q&A, Help & Troubleshooting] zige:
I tried these settings with Ex kernel app but didnt see anything to happen. Maybe im used to yellow tint now... :p Dunno know..
[Nexus 6P Q&A, Help & Troubleshooting] dewankpant:
Did the high brightness mode work for you? Is the screen brightness pretty high in direct sunlight? If that didn't work too then there's some other issue. Coz maybe the tint isn't but high brightness would be clearly noticeable.
[Nexus 6P Q&A, Help & Troubleshooting] quempas:
I like these settings. Thanks for posting!

On ex kernel manager, there are also cool tools for getting high brightness, like the widget by flar2 and the hbm widgets in the play store. They seem to work on most all of the custom kernels for 6p.

I'm one of those people who have to remind themselves to check the apply on boot toggle to make sure that the settings stick.
[Nexus 6P Q&A, Help & Troubleshooting] dewankpant:
You needn't use toggle for high brightness as franco and ex kernel both have the option where you can set a threshold that hbm turns on itself under certain amount of external light. Kinda like ambient light, and btw if you liked the settings press the thanks button there ????
[Nexus 6P Q&A, Help & Troubleshooting] quempas:
That's great advice. I have to confess tho that I find the toggles fun to use. Just weird that way I guess.

On a separate note, my thanks button hit is still showing for me on your post. Still says that quempas thanked you. I'll double check when I'm near a computer. If I thanked the wrong post I'll thank the right one. Love XDA labs app but I'm still new to it.
[Nexus 6P Q&A, Help & Troubleshooting] appileh:
I got all the problems, even after fix/repairing the screen (from a big repaircentre) etc.

From Yellow/PINK HUE to vertical banding to uneven brightness, the buzzing sound from my headphones, unbalanced speaker and a big shi*ty muffle voice when i'm in a call. One positive thing about the phone it is real stock Android experience everything is snappy but the build flaw/fail design is irritating me as hell, quality check is 0 to -10. Even the Axon 7 has less problems compared to the Google-Huawei phone.

What kernel manager are you using with ElementalX?
[Nexus 6P Q&A, Help & Troubleshooting] Appl3.Pi3!:
I got a second-hand 6P last Saturday and it took me one day to realise what a strong yellow tint it had... I didn't know about it, I just read reviews before buying it and apparently nobody mentioned it. :( I seem to understand that due to the AMOLED technology all 6P have a yellow cast, but for some that's way too much. Is is correct?

Anyway my question is: is there a way to calibrate the screen without rooting the phone? I really want to use Android Pay and I don't think that can be done with rooted phone. It looks like System UI tuner was providing a way to calibrate colours but that's gone in 7.1.1 I've tried Screen Balance from Google Play, which kind of works but it uses an overlay which means it reduces contrast and black are not true blacks any more.

Please help! I really like this phone apart from this issue and I don't want to return it! :)
[Nexus 6P Q&A, Help & Troubleshooting] hltbest:
Its possible you have one of the 6p which has a rather yellow screen. You can try to calibrate it by flashing a custom kernel and using the tuner in an app.

You can always root to do this and then unroot permenantly (which is what I do) to use android pay. I only root to set up my phone, then unroot.
[Nexus 6P Q&A, Help & Troubleshooting] hltbest:
Just to say, I got a replacement due to the battery issue... And this one has a MUCH whiter appearing screen than my previous 6p. I had complained about my first one appearing too yellow, and this just makes me annoyed they told me it was normal... When clearly it wasn't!

I'm happy at least this one has a good screen and battery!
[Nexus 6P Q&A, Help & Troubleshooting] Appl3.Pi3!:
And can I re-lock the bootloader as well? I thought that wouldn't work except with stock firmware.

So maybe I should return this - which I can - and try another one...
[Nexus 6P Q&A, Help & Troubleshooting] jhs39:
I don't believe you can relock the bootloader if you have a custom Kernel. My understanding is that everything has to be stock or you are asking for trouble. If the screen bothers you I would return the phone.
[Nexus 6P Q&A, Help & Troubleshooting] Appl3.Pi3!:
I think that too. Anyway, nevermind locking the bootloader. I rooted the phone systemlessly, installed Magisk and ElementX kernel and I can calibrate the screen AND use Android Pay. Everything's great.

But, another question: I noticed that whenever I tilt the screen to any direction the screen gets a strongly bluer/greener cast. I tried to ask Google but I cannot whether that's expected or not. Is it so with AMOLED screens?
[Nexus 6P Q&A, Help & Troubleshooting] A2Eric:
I made the mistake of comparing the 6p to the N6 and the N6 colors are more rich blacks and just looked better to me (of course maybe because I'm used to the N6). It was just shocking, like going from Amoled to LCD shocking. Oh well, I've calmed down a bit since last night. Will see how it goes. I can always RMA it.
[Nexus 6P Q&A, Help & Troubleshooting] graffixnyc:
Yeah that's how I see it, that I can always RMA. I don't want to RMA right this second because I have one Quartz 5X I'm returning completely (keeping carbon) and then my carbon had a yellow tint so I got that replaced and they put a hold on for a the defective one. So right now my CC has 3 phone charges and a hold for a 5x replacement. Once they refund me for the 5x I'm returning and remove the hold for the defective one then I think I'll order a replacement 6P
[Nexus 6P Q&A, Help & Troubleshooting] istrikerx:
They have the horrible Samsung displays unfortunately. The bottom of my 6p is yellower and brighter, where as the top half is pink and dimmer. Doesn't really change much if screen tilted.

This was a common problem with the note 4, every screen was defective in this way, but a software app (screen eq, on the app store) was able to even out the colours. Surprise surprise though, 6.0 has broken that app till its updated.

I just don't understand how Samsung can create brilliant evenly coloured screens for the s6 line, yet every time (from note 3 onwards) they fail at making a nice looking large AMOLED screen for the "phablets".

I've attached a picture to show just how much of a wreck the screen is. I've also noticed that under certain lights you can see that the top of the screen panel is bent inwards. This in itself is more than likely causing the issue. Slight bend = uneven OLED lighting = dim area with pink tint.

It isn't the actual screen that's uneven, its the fact that it's bent slightly, so you see all the pinkish off angle hueues when you're looking straight on. Tilt the device enough and it disappears, but then the rest of the screen is a completely different colour.
[Nexus 6P Q&A, Help & Troubleshooting] bobafuzz:
Anyone see the screen get really pink at extreme angle, almost flat? Is this normal with AMOLED?
[Nexus 6P Q&A, Help & Troubleshooting] jeff5347:
Does anyone have a one plus one to compare to... Reason I'm asking is my friend has a galaxy 6... I thought his was super bright 'til I put my 1+1 next to it and my 1 was way brighter and whiter.. His has a more yellow tone to it...
[Nexus 6P Q&A, Help & Troubleshooting] bretrick30:
I'm thinking its just normal with AMOLED. I just tried with my S6. With a white screen, as I tilted the phone it went from white, to a slight blue, then green, then pink.
[Nexus 6P Q&A, Help & Troubleshooting] luciferiusXI:
Not normal.

Latest samsungs dont have that. I think the 6p uses the note 4 screen.

---------- Post added at 10:10 ---------- Previous post was at 10:09 ----------

I wonder when will the day come that you buy a nexus and don't need to wait 3 months to fix it
[Nexus 6P Q&A, Help & Troubleshooting] just4747:
I also have yellowish tint and I was using the free app Screen Adjuster to adjust it to be cooler until two things:

- I noticed that the app ONLY changes the tint of the screen everywhere but where the nav bar is, so when it's enabled and you look at the homescreen where the nav bar is clear, you can see that that bottom part is still yellowish and the rest is adjusted to be bluer.

-I read that using a screen temp tuning app like this on an OLED screen may cause it to change permanently to some degree overtime due to its nature (not sure what exactly would stick/change over time but it may not be in a good way), so I definitely don't want to make it any worse.

Been debating since the first 10 min I got my phone yesterday whether I want to try for a second one from Google to see if I get luckier with the screen, but I can't decide. Don't really want another pre-auth charge on my card for weeks. I get so unlucky with screen in this sense. Comparing it to my G3's LED screen, it is so much warmer, yellower - whites are not pure white at all...

---------- Post added at 11:16 AM ---------- Previous post was at 11:14 AM ----------

Mine does it too..but like at really extreme angle. I think it is "normal".
[Nexus 6P Q&A, Help & Troubleshooting] luciferiusXI:
The fact that yours does it too, doesn't mean that it is normal. Mine does it too and I find it super crappy and annoying because I had the s6 and note 5 and none of them had such ugly tint. If there are others saying that they have it too, then better go replace it because no way this is normal.
[Nexus 6P Q&A, Help & Troubleshooting] istrikerx:
Ah right. Had a feeling it was the note 4 display purely because all my note 4s had the exact same area affected.

I also found it dubious that all the reviewers stated it was the note 5 screen, when it's a well known fact that Samsung don't sell their latest gen displays to competitors.

Just like how the Nexus 6 got the even more woeful Note 3 display tech. Literally every note 3 I came across had patchy pinkness everywhere. At least the note 4 was somewhat uniform (as in, it was easy to find the area of the screen to fix with the app).

Glad to hear the note 5 doesn't have the issue though, means they've finally got the hang of large phone displays.

We don't have the note 5 still here, but I did notice the Edge+ display had no uniformity issues. It was flawless like the normal s6 range.

I did notice the almost green cast across the whole screen, but that's present in all the latest amoled panels. They really need to include display calibration settings out of the box.
[Nexus 6P Q&A, Help & Troubleshooting] just4747:
For me, the pink tint at extreme angles is very slight and it is literally only when I tilt it to the max possible - I didn't even see it once until I checked due to this thread - very much a non-issue (especially compared to the screen tint issue in general).
[Nexus 6P Q&A, Help & Troubleshooting] daivee:
Same here. Never had an amoled display and have my doubts that my screen has a tint.
[Nexus 6P Q&A, Help & Troubleshooting] hltbest:
Well here is a screenshot which shows the yellowness.. As people have said when using screen filters the bottom 1cm of the screen is not changed. Therefore you can see the original 'yellow' tint at the bottom compared to what it looks like with edited screen calibration settings.

Does that look like something I need to return or can it be fixed with an update or something?
[Nexus 6P Q&A, Help & Troubleshooting] bobafuzz:
Right, it's only at the extreme angle for me, I'm not sure if it's worth RMAing, would just be a gamble for some other issues. Was just checking to see if I'm not the only one experiencing it. I just got a hold of a Note 4, it does have a slight pink tint at extreme angle but not as pink as the 6P, there's a screen protector on Note 4 though, naked 6P.
[Nexus 6P Q&A, Help & Troubleshooting] graffixnyc:
Hardware issues would NOT show up in a screen shot.. that's all SW's doing.. So if your SS has a tint then that would infer that it's a SW problem in your case..
[Nexus 6P Q&A, Help & Troubleshooting] hltbest:
Okay that's good to know thank you! I'm assuming that means a few modifications and I could be all sorted!
[Nexus 6P Q&A, Help & Troubleshooting] bigdave79:
Yes, my Oneplus One display has a much cooler (whiter) color temperature and appears to be brighter at equivalent settings. I'm definitely not used to the yellow/warm display of this phone. I'm hoping it improves with time or we can tweak it with software fixes.
[Nexus 6P Q&A, Help & Troubleshooting] Aridon:
What that looks like is the navigation bar is drawing the screen color differently and the app you used to make the colors cooler isn't changing that particular section. The settings probably reside in a different file not being touched or perhaps can't be altered without root. That isn't a hardware problem otherwise when you took the SS of it you wouldn't be able to see it. Hardware issue would only be visible from a photo taken of the device. Similar to say taking a screenshot of a cracked screen and it not showing up.

I wouldn't stress about the color so much as that can be altered.

What I would stress about is if your screens have obvious defects. One guy above posted where the screen was denser with color in one section of the phone. ALmost like someone pressed hard and caused a smudge or something. I'd return a device like that looks more like a hardware issue than anything else.
