[Nexus 6P Q&A, Help & Troubleshooting] NateK:
That's probably why/how Hauwei was able to meet the pricepoint target they were given by Google. Take Samsung's B and C grade panels to save cost.

That, and their QA process is garbage

---------- Post added at 01:33 PM ---------- Previous post was at 01:13 PM ----------

So I'm trying to go about replacing my 3rd device. I spent an hour this weekend talking to someone - was promised an e-mail with instructions and then got nothing.

I spent an hour on chat with them today and the guy I talked to was clearly incompetent and we got nowhere. Eventually I told him I had to go.

I want to speak with someone who will acknowledge the problem and give me a path to a good device. Is that possible? Clearly, playing the device replacement lottery is not working well.

Do I need to ask to speak to a supervisor? Will that get me anywhere in getting better guarantees i.e. extra inspection https://www.reddit.com/r/Nexus6P/comments/3ujfol/nexus_6p_pink_screen_response_by_google/
[Nexus 6P Q&A, Help & Troubleshooting] joshuadjohnson22:
Got my 4th on the way. I don't have an issue getting a replacement when I use the chat so if you are having issues use the chat and not the phone. usually in 15 minutes I have my email. I hope this is the one, i hate the muddy whites... just gross
[Nexus 6P Q&A, Help & Troubleshooting] sharpehenry:
after few replacements, I've decided to give up and requested for the full refund. I'll just go back to my LG G4. after using Nexus 6P for around 20 days and going back, didn't realize how brilliant LG G4 display was. wish it was little bigger, don't want to spend to buy V10. maybe Huawei wasn't ready for the bigger scale, maybe Huawei rushed a little, maybe I was just having bad luck with this device, maybe all of the above, maybe I'm just picky on displays. google was being superb regardless . I'm having a mixed feeling right now. Nexus 5x is just little downgrade from G4 so I think I'll just stick with my G4 and wait for the next nexus line. I know I'll get few bad comments with this but I think it is what it is.. I can deal with few dings but I'm just too prioritized on displays.. maybe I got brainwashed with Samsung's displays. I wish you all good luck. see you guys in future nexus devices.
[Nexus 6P Q&A, Help & Troubleshooting] S60tonexi:
I have mixed feelings about the screen issues. Mine is not perfect, but it is good enough to keep. While I'm not denying that some panels are really bad, I believe that the whole issue is overblown a little bit. Simply put, perfect amoleds are few and far between, and people who are used to lcd uniformity are expecting something they are not very likely to get. I'm OK with less than perfect whites in exchange for perfect blacks, rich colors and no backlight bleed. Samsung Galaxy Tab S 8.4 is universally regarded as having one of the best displays on the market, and for a good reason. It is absolutely stunning in each and every way except that it is not perfectly uniform and there is a color shift when viewed at an angle. How does this affect my usage? It doesn't. Every time I turn it on I'm blown away.

Yes, some of these screens are really bad and should not have passed QC. Some are 100% uniform and don't have any overwhelming hue (cooler or warmer is a matter of preference).

The thing is, vast majority is somewhere in between and instead of wondering if display is 100% perfect users are better off asking themselves whether they like it or not.
[Nexus 6P Q&A, Help & Troubleshooting] Tones1971:
See im struggling with this. If AMOLED isnt as good as LCD (And the display on my nexus 6p wasnt as good as LCDs ive had recently) then why use them? Arent they supposed to be the future? Arent they supposed to be an improvement on LCD? Surely viewing angles and whites should be stunning?

And i still think back to when i had my S3 with AMOLED screen. I loved it. Whites were white, blacks were black. I loved the saturated colours and they didnt change when i tilted the screen. Cant understand why AMOLED screen on this device is so bad many years after I had a great S3 screen.
[Nexus 6P Q&A, Help & Troubleshooting] joshuadjohnson22:
I know what you're saying, The G4 has the best screen quality I have ever seen. I wish they used the quantum IPS in the 6P, it would make it the perfect device. I've never seen an LCD with such dark blacks and vivid colors. I hope you enjoy it. If I had to leave I think I'd try the V10 so I do not miss the fingerprint reader
[Nexus 6P Q&A, Help & Troubleshooting] S60tonexi:
Well, I don't think that one is necessarily better than the other. Both have strengths and weaknesses. To me, amoled is better than lcd in all areas except for whites and viewing angles. I actually looked at someone's S3 the other day and whites were too blue/green for my taste and viewing angles were little better than 6P but worse than any decent lcd. My wife's Note 3 is also more blue/green. What I personally like about amoled is that it produces a lot more naturally looking image than lcd. Like plasma TV vs lcd TV.

Basically, I'm yet to find a screen that is 100% perfect in all areas.

Now, some of the screens posted here looked really bad and I would return them without thinking twice but some were fine imo.
[Nexus 6P Q&A, Help & Troubleshooting] D47x:
The pink hue on my old Nexus 6 was way more extreme in low brightness, to the point where i thought it could be an actual defect, given this is the first time i've seen something like this on an OLED display
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
The screen just doesn't look nice. Aside from the pink, it's the muddyness that's gets me too. Even my Moto 360 screen looks much better. If my S6 want so locked down it would be a no brianer over which to keep.
[Nexus 6P Q&A, Help & Troubleshooting] sungoesdown:
I've been following along in this thread as I've been evaluating concerns with my own 6P display. While I wouldn't characterize the non-uniform pink hue in my device as excessive, it's certainly noticeable in the top right third of my screen. I randomly asked my wife the other day if she could make any observations about the display (on an 18% gray screen) and she jumped all over the pink hue. Needless to say, I just finished requesting a replacement from Google, the entire phone call took seven minutes - very impressive customer service! I'm not hopeful that the replacement will be acceptable, based on the poor results that others have posted here. Though it's worth a shot because non-uniform whites on a 2015 screen on a $550 phone is wholly unacceptable.

The last few comments regarding general AMOLED quality have been slightly disconcerting as I (naively) think "muddy whites" shouldn't be an issue in 2015. While the whites can certainly look different from and LCD for numerous reasons, clarity and uniformity shouldn't be sacrificed. Better yet, these are supposedly the latest-gem Samsung panels; however, I don't see many issues with those devices. That's what I'm scratching my head on.

I'm also confounded by uniformity and clarity (particularly whites) not being addressed by all major reviewers. I made a point to re-read a dozen or so reviews, not one mentioned concerns with the uniformity/clarity of whites. Instead, the majority fell over themselves to praise the screen, while a minority had common AMOLED saturation concerns. In the light UI world we currently live in (Messenger, FB, Hangouts, web browsing, etc.), I'd expect hue gradients to be noticeable to professional reviewers.

---------- Post added at 01:25 PM ---------- Previous post was at 01:16 PM ----------

Just for the heck of it, I just fired up my wife's old Moto X 2013. Despite some minimal burn-in, the whites on that old AMOLED display are 100% uniform. The side-by-side comparison is almost laughable, which further highlights my earlier post questioning how white uniformity is even a thing in 2015, especially on the Nexus 6P. I no longer feel bad about requesting a replacement after comparing my supposedly high-end AMOLED to that 2013 AMOLED panel.
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
I think Samsung are effectively "binning" their displays and selling their lesser grade displays to Huawei. There's just no way these displays are top range Samsungs. Huawei probably know this and paid less for them.
[Nexus 6P Q&A, Help & Troubleshooting] sungoesdown:
I agree that's a very real possibility, and it's absolutely worth exploring in relation to this issue. However, in your opinion, how would you explain the inability for professional reviewers (that stare at the varying display grades all day) to overlook the screen inconsistencies in the 6P? Moreover, do you have any thoughts on why the 2013 Moto X display trumps the 6P in terms of uniformity? (For the record, it doesn't hold a candle to the 6P in any other category like color reproduction, resolution, contrast, etc.)
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
I really don't know about the reviewer displays, perhaps Google send them hand picked well calibrated displays whilst we get the rest or perhaps the reviewers just aren't very good?!
[Nexus 6P Q&A, Help & Troubleshooting] wazka2:
Like someone mentioned before its very surprising that none of the known android sites or YouTube channels actually go into the problem?

They all must have received carefully selected devices aka samples ;)

But some of them bought them like us and still don't comment on this issue.
[Nexus 6P Q&A, Help & Troubleshooting] Metallice:
These are just Note 4 displays. The measured power efficiency of the display according to an andandtech reviewer is within margin of error of the Note 4's screen. Like 4.5% better. Something like 15+% more power hungry than the panel in the Note 5.

I have an s6 edge to sell. Also a Galaxy S4 as backup. The 6P viewing angles, whites, and colors are just worse than the S6 in every way. It's clearly between the S4 and S6 in quality.
[Nexus 6P Q&A, Help & Troubleshooting] B_I_N_G_E:
FWIW, I bought my 5th 6p yesterday and it was the first one to ship from SOCAL. It is PERFECT. Maybe Google really has set up a new QC facility.
[Nexus 6P Q&A, Help & Troubleshooting] WizeGuyDezignz:
I wonder if that has something to do with it. I live in San Diego and mine shipped from Northern California. I have absolutely no complaints about mine.

In fact, I have been scratching my head reading this stuff. First one ordered and perfect over a week later.

And I have a Note 5 to compare it directly against. So I would know if the screen looked really bad. While it doesn't get as bright and the whites aren't as white, it stands against it pretty darn good.
[Nexus 6P Q&A, Help & Troubleshooting] NateK:
What area of the country are you in? Maybe just coincidence?

Then again, all 3 of my defective devices have shipped from Illinois since I'm in the Midwest. Will be ordering #4 soon...
[Nexus 6P Q&A, Help & Troubleshooting] B_I_N_G_E:
Well mine were coming from Illinois and Canada. I'm in Jville Florida.
[Nexus 6P Q&A, Help & Troubleshooting] dhruvmalik:
I have a 11/11 batch; getting my replacement tomorrow of Aluminum 64gb; I would assume it would be from the same batch, but that necessarily is not a bad thing.

Pink tint on the top Status running down the right side and a blueish muddy tint on the remainder of the left side and bottom navigation bar area. Dont mistake the photo color tinting from a different viewing angle, but rather that the pink is there.

Its so subjective that I sometimes dont see it, but on grey or dark points that pink tint highlights itself so much that it doesnt satisfy your heart to keep this unit.

Lets hope for the next one to be good.

P.S - I went through 5 replacements for the N6 last year cause of the screen Finally found a completely white uniformed screen with no muddy spots and awesome speakers.
[Nexus 6P Q&A, Help & Troubleshooting] markwebb:
Well my third one still exhibits the pink screen though it is the least offensive of all of them. It is particularly noticeable when I drop the screen brightness down (not using Adaptive). Since I bought a new one (prior 2 were refunded) on Black Friday, I have until January 22 to get a full refund. I will see if I "get used to it" or if it is still annoying to me by then. Perhaps later builds will be better, but after 3 I am doubting it. This is my first time EVER where I have had an issue with a phone or any phone for that matter with multiple returns. Perhaps I should just wait till next year's model since my N6 is working well: I just really like the N6P fingerprint scanner and improved camera but still think my N6 processes things faster (backups, app installs, etc.). We'll see. Again, I really think the panels are not top tier and Sammie is selling Huawei lesser quality panels.
[Nexus 6P Q&A, Help & Troubleshooting] jjschafe:
I received my 5th phone yesterday and it is one of the worst so far. Left side to middle is pink, then vertical green stripe down the right side. Having a left to right color gradient is much worse than top to bottom, because reading text is like scanning over a rainbow.

FWIW, all of my phones have shipped from Illinois. I'm kind of at a point where I've been through 5, so what's 5 more? As long as google will keep sending them, I may just keep trying. I will say that the phone I am using now (#4) is at least much better than the original.
[Nexus 6P Q&A, Help & Troubleshooting] NateK:
Ugh, that sucks. My most recent replacement was very similar to what you describe. Needless to say, it's getting shipped back today.

They always want me to ship one back before they'll replace the other, so I probably won't get to order a new one until next week. Hopefully that gives them time to get their QA process figured out, but I'm not optimistic.

I plan on doing replacements until I get a good one. They should pay me for being their QA department...
[Nexus 6P Q&A, Help & Troubleshooting] jjschafe:
Ha, maybe you just unlocked the secret to their business model. We ARE their QA/QC :D

I have been using their chat to do my returns, but I think I might call today and see if they have advice. Maybe hold on to one of them for a week or two before trying an RMA again.
[Nexus 6P Q&A, Help & Troubleshooting] NateK:
I asked the guy I spoke to yesterday if this was a common issue or if they had a special process. He said no, just that it would be handled like a manufacturing defect. Seems surprising to me given the prevelence of this issue.

---------- Post added at 09:37 AM ---------- Previous post was at 09:34 AM ----------

Another thought, SoCal is closer to China so maybe they have the newer batches. What is your PERFECT device's build date? [Power Off, then power on holding Power+Vol Down, scroll to Barcodes using volume, press power to select]
[Nexus 6P Q&A, Help & Troubleshooting] Tones1971:
They told me they had no other complaints about the screen. Just looking at this and a couple of other threads will tell you that's nonsense. Some as you see have returned their phone multiple times
[Nexus 6P Q&A, Help & Troubleshooting] Dyln:
I put up a video to compare mine to yours. Ive gotten a uniform yellow screen with what I think is horrible viewing angles. Though im coming from LCD so dont really know whats normal. It goes from yellow to blue with even the slightest movement, almost like its flashing between yellow and blue when im browsing the phone with my thumb.

It looks a little bit better on the video, also looks more like its going from white to green than yellow to blue, but it will give you an idea.

(Full brightness, addaptive off, sRGB)

https://youtu.be/XhEC4dE5XHg

This cant be normal for a 2015 AMOLED right?
[Nexus 6P Q&A, Help & Troubleshooting] Raijin:
Congratulations! What is the build date of your device? Like [MENTION=4834820]NateK[/MENTION] said, this is how you can get it:

Power off, then start the device holding Power + Volume Down to enter Fastboot. Scroll to "Barcodes" using Volume buttons, and press Power button to enter. The build date is under the third barcode.

It would be interesting if people posts their manufacturing date when they talk about their screens.

---------- Post added at 05:14 PM ---------- Previous post was at 05:14 PM ----------

I received my device two days ago. It has a pink tint across the left side of the screen. The right side looks greenish. I hope it gets better in the next days, because it was worse the first day. If not, I will request a replacement next month, with more probability to get a newly manufactured device.

Build date (mm-dd-yyyy): 11-5-2015
[Nexus 6P Q&A, Help & Troubleshooting] jimbodan:
I'm about to send back my 5th device. All 5 have had the issue. Luckily #3 was very minor so I'm going to keep it for now I think and then possibly RMA it in the future when hopefully the issue is fixed. Despite the chat representative telling me it would be easy to just keep my original device and send back the RMA's, it has been a mess trying to do that. The first time I tried that I had to explain it twice and then the rep ignored what I said and processed a refund instead, had to get a supervisor to fix it. This last time was smoother but I'm still not convinced that my Nexus Protect will end up on the right phone. This last time I asked to talk to a supervisor about the pink tint. and this was the conversation:

Me: I seem to keep having issues with getting phones that have a pink tint on part of the screen. Each replacement I get has had the issue to some extent. Some worse then others. I keep trying to get a phone with a uniform screen and I have not succeeded yet. Is this a widespread issue that you are aware of or do I just have terrible luck with this phone?

Supervisor: We have seen this with a few phones, however as per our product team the issue seems to get resolved after a few days of usage usually.

Having said that, I would definitely pass on your feedback to them.

Me: Unfortunately, for the ones I've gotten the issue never went away. The one I currently have is least worse of the bunch and I think for now I'm going to try and live with it, but if I do decide to RMA later on Is there anything I can try to do to get a phone with a uniform screen, or do I have to just keeping RMAing and hope to get lucky?

Supervisor: I can understand where you coming from Tom. All products which are shipped out of Google warehouse are tested and certified. However, I do agree in some cases issues still seem to be there with a few phones.

I can assure you that in case you want to go for RMA of the device, the next product will be to your satisfaction.

Like I mentioned I will personally put in this your records also.

Me: Ok, thank you. I just wanted to see if Google was aware of issue and if it was widespread or if there was any type of fix coming

Supervisor: There is a reference number that I can provide for this conversation in case of any further communication from your end on the same.

I'm supposed to get a follow up e-mail on Monday to see if I want to try another RMA or not. At this point I'm tempted to just give up. I might give it one last try though. I was really hoping that Google was doing something to fix this, but it doesn't look like they are.
[Nexus 6P Q&A, Help & Troubleshooting] jjschafe:
The device I just received (device #5 for me) was built 10-14-2015. Heck, it was probably one that one of you guys already sent back.

The phone that has been the best for me so far (#4) was built 10-31.
[Nexus 6P Q&A, Help & Troubleshooting] WizeGuyDezignz:
My build date is 11-6-15 and was shipped from Northern California.
[Nexus 6P Q&A, Help & Troubleshooting] markwebb:
Isn't this utterly amazing and I feel your pain. Cheap second tierscreens, plain and simple.

I don't buy this "wait to glue dries" crap either which is a cop out. If your shiny new 65" 4k HD TV or 30k new car had unfixable screen/window variations, would you keep "after a few days of usage?" I think not. I had one replacement for 2 weeks and it never changed.

Google and Huawei are not being responsive and is more interested trying to push sales while dodging poor QC or bad sourcing. Just IMHO.
[Nexus 6P Q&A, Help & Troubleshooting] sungoesdown:
This is the type of anecdotal comparison that I'm looking for - a Note 5 vs. Nexus 6P display comparison. In at least some cases, the display

does

at least rival other top tier displays. It also substantiates some of the YouTube reviews by smaller name reviewers (assuming the more popular reviewers received handpicked units). Lastly, it is indeed possible to find acceptably perfect replacement units.

Unfortunately, there's plenty of evidence to suggest a fair amount of second tier displays and/or widespread QC issues. (Widespread in the sense that it's not localized to a specific geographical area or production date.)

---------- Post added at 01:49 PM ---------- Previous post was at 01:45 PM ----------

For what it's worth, my original unit shipped from Carol Stream, IL with a build date of 10/26.
[Nexus 6P Q&A, Help & Troubleshooting] Metallice:
Everyone is being harsh on Google and Huawei, but let's not forget it's Samsung shipping these "approved" panels to Huawei for phones. Some tint issues are due to manufacturing where the screen doesn't lay flat (Huawei's fault), but I think most is due to the the panels having inherent non-uniformity. That's Samsung's fault. (Although Huawei should be checking and returning faulty panels). Their own phones have had these issues since going to 1080p+ (mo' pixels mo' problems) and they don't seem to care enough to fix it. (At least with s6, not sure if it was fixed with s6e+ and note 5).

Cmon Samsung.
[Nexus 6P Q&A, Help & Troubleshooting] NateK:
QA of received parts is ultimately the responsibility of the company putting everything together (Hauwei). They're the ones who will eat the losses should they need to handle hundreds/thousands of returns.

Comparison

i made a little comparison between ( Nexus 5 Vs Nexus 6P) and ( NOTE 4 Vs Nexus 6P) to show the yellow Tint .. here are the Pictures , tell me your opinion , shall i RMA or not .
[Nexus 6P Q&A, Help & Troubleshooting] Batfink33:
The bottom pic looks a mess, a gradient from one side to the other. Ultimately it's up to you whether you like the screen or not.

On a side note, I don't believe these are Note 4 screens, my Note 4 had no such problems and looked great. These panels are definitely B grade panels and it wouldn't Suprise me if that's what Huawei are paying for.
[Nexus 6P Q&A, Help & Troubleshooting] hdlhkhgikn:
Sorry i didn't get your point clearly , did you mean that This Nexus 6P display is bad !! ? .. BTW this is real Note 4 , i tested two note 4 and they are the same .
[Nexus 6P Q&A, Help & Troubleshooting] sungoesdown:
I'm not noticing any discernible color gradients (in fact the uniformity looks pretty good, if not great, to my eyes), though the color temperature is most certainly different between the three devices.

There was a post much earlier in this thread that perfectly illustrated the affect of color temperature on the perception of whites. The chart showed that displays calibrated closer to 6500 would have a yellower tint. I'm not sure any with a 6P has a colder calibration (i.e. whites that are more blue), so an RMA may not resolve your dislike of the warmer temperature.
[Nexus 6P Q&A, Help & Troubleshooting] Metallice:
Not saying otherwise. I said that Huawei should be checking them and sending back crappy panels. Still doesn't excuse Samsung for continuing to produce and use/sell bad panels and trying to pass them off as fine.

This issue has gone back to the S4. Not even a joke. I had to return 1 or two S4s to get one that wasn't pink on the top half. Same with the s6 edge. I understand that the number of RMAs and returns they have to eat is nothing compared to the cost of tighter quality controls, but it still sucks.
[Nexus 6P Q&A, Help & Troubleshooting] sungoesdown:
You had the same issue with the S6 Edge? Were you finally able to get a device that worked for you?
