So the Nexus 4’s potentially quality screen has crappy screen issues. There. I said it.
What I mean is that it’s a GREAT screen in some ways (resolution mainly) but it’s let down by what seems to be noticeably poor quality/manufacturing.
Why do I say this? Well, it’s been my experience that the Nexus 4 (in general) has a chronic problem with significantly poor screen uniformity for both colour and brightness. I ordered my first phone on the 13th December 2012 and as soon as it arrived I was pretty excited at finally getting a new phone (upgrading from Galaxy S1 the N4 is a beautiful beast).
When I booted it up and started using it I immediately got a sinking feeling as I realised that the bottom third of the phone had a slight but easily noticeable yellow gradient tint to it along with the left edge and the right edge was grey/dingy about a half a centimetre in. The left side and bottom third were also noticeably brighter than the right side of the phone. I’ve illustrated this in the attached pic. It’s all fairly subtle – but it’s definitely there and is easy to see.
Since I use (like most people I guess) quite a few apps that have white or solid colour backgrounds (gmail, currents, google books, email, messaging, chrome etc) – this lack of uniformity really made things look crappy in a not spectacular but just “sub-par” way unless I was viewing something which was a picture or video or filled the screen where it wasn’t noticeable.
So I called Google Play and told them about the problem and they arranged for a return.
When I got my replacement I booted it up and immediately, even before getting past the X logo animation noticed a big spot of light bleed at the top right. *Very* easy to see and my heart sank.
There on in I opened up the Mail app and closed the keyboard so I got a nice, mainly white screen. Again I noticed the same issue with the yellowing tint to the bottom and left but this time it was *more* noticeable.
To cut this long story short I’ve now sent back 3 devices for this issue, about to send back my 4th and my 5th should arrive tomorrow. I’m not holding out much hope.
I’ve seen this exact same issue on about 4 other Nexus 4’s in shops in the UK (Carphone Warehouse, O2) and while there looked at the HTC One X, iPhone 5 and the new Lumia phones from Nokia running Windows Phone 8. Those phones in particular (with LCD screen tech too) didn’t have these issues *at all* as far as I could tell. In fact the HTC One X screen looked to me to be flawless, as did the Lumia 820 and 920. If I could put the screen from the One X into the N4, I would. Sadly, not gonna happen. Sadly I don’t want the One X but do want an N4. P.S. I know LG manufacture their own displays.
Now I’m NOT claiming to speak for ALL N4’s (why I’ve started this thread) but I do believe that it cannot be a coincidence that ALL the N4’s *except one* showed this issue. I believe that LG simply manufacture the screens in such a way that they invariably have these tinting and brightness uniformity inconsistencies and that because most people don’t care, they don’t care.
********What I’d like is to ask if people with an N4 they’re happy with could do the following and provide the following info:
*Open the Mail app and close the keyboard (press down arrow at bottom). Look at the white of the screen and see if there is any edge or part of the screen that is noticeably *brighter* or *more yellow*. Are there any areas of the screen that are noticeably darker or duller? Do this for different brightnesses (low and fairly high). What do you see? Any yellow tint? Any inconsistency in brightness? All ok? Perfectly even?********
TL;DR: I’ve had 4 Nexus 4’s from Google Play all with the same yellow tint and brightness uniformity issues. Very noticeable. Not acceptable to me for a device that displays a lot of white “pages” and solid colours. Other phones (that I don’t want) do not have this issue (annoying). Please can you give feedback from your phone.
PLEASE NOTE:
Other threads discussing the “yellow tint” issue invariably attract trolls in their varying forms.
DO NOT reply to this thread if you simply want to say any of the following:
1) I don’t see a problem with mine therefore I don’t understand what you’re talking about.
2) I don’t see a problem with mine therefore you’re imagining a problem with yours.
3) I don’t see a problem with mine therefore you’re expecting a “perfect” screen and they don’t exist.
4) There are more important things in life to worry about. (A: I’m not “worried”, screen uniformity is important to me, get over it.)
5) I see a slight yellowing but I don’t care therefore you shouldn’t care. There are more important things in life to worry about.) [see above]
The attached illustration is slightly "exaggerated" to make sure the effect is reproduced for all screens. Not by all that much though.
UPDATE: 31/01/2013: Well I've received *another* N4 replacement today and lo and behold the exact *same issue*. With this one I'm going to wait it out at least a week and see if it improves. I *really* want an N4 as in every other way it's truly a great piece of tech. Pray for me guys!

My screen has no discolorations or brightness unevenness that I can see.

I've had tint issues with all three handsets. First two it didn't disappear after use. This third handset SEEMS to have gotten a little better after a week.
All three had light bleed. First one was least noticeable, last two including the current have two blobs of light bleed in the exact same places along the top of the LCD.
It's almost as if something during manufacturing (screw tightness?) has caused it on both handsets. They are both 212K and revision 11.
It's annoying me and I may do one final RMA once I see what this new wave of devices brings.
mine's fine.
I did what you asked, OP and I'm not seeing and unevenness, yellow tint, or brightness issues (aside from auto-brightness being stupidly low).
The only issue I have with my screen is poor colors. I have a One X and an iPhone 5 that I sometimes compare with my N4's screen and it's shockingly apparent that the N4's screen has colors that just aren't worthy of a top-tier device. The resolution is nice and all, but I like it when the colors are nice and accurate. It's most easy to tell when comparing images of people and looking at their skin. Now I'm no anthropologist, but I have a pretty solid grasp of what skin looks like. The One X is probably the best at representing things the way they look IRL, followed by the iPhone 5. I don't know if it's just my N4 or other people have the same issue. I've tried using apps to adjust the color (FauxClock with Faux's kernel, to be specific), but nothing makes it look quite as nice as my other phones.
I guess you never asked about the second part, but there it is.
I had that issue when I received my device, Used kernel setting to rectify the problem but after 4-5 days of use it gone away. Now device is perfect.
I recommend you to stay with it for 3-4 days before returning it and check.

Thanks for the feedback - very helpful. I got *another* one through today and it seems "better" by a bit than the previous one at least. I think I'll see how it goes. Good to know that it's not only me sho can see the difference.

All the phones I've had have been 301K and they've all had the same issue with yellow tint/backlight inconsistency in a very similar way. I'll have sent back 4 N4's if I decide to keep the current one! I think you're probably right about the screw tightness or some such other minor thing during manufacturing. It's not like a viewing angle problem. It does look like something to do with assembly in particular. Please do let me/us know how you get on and how things work out.

I used FauxClock on my previous device (sat here waiting to go back) and it did seem to improve the situation slightly - but then since the screen isn't uniform, it reduced the yellow where it was yellow but then made it too "blue" on the rest of the screen. I really hope that this yellow tint is a "glue" issue or something that will even out through repeated use due to heating/cooling - i.e. expanding and contracting which somehow settles things down. I'll keep this one about a week and see what happens. Fingers crossed!
Thanks for your feedback guys!

^ this is pretty much all I can say.
Every nexus 4 phone I handled had a slightly yellower screen at the bottom. For me its barely noticeable, not as yellow as it is in your illustration.
They all seem to have that same issue, along with light bleeding across the top edge.
You can keep RMAing if you're not tired of that .. But you will not receive a fully uniform no matter what.
If screen uniformity is important for you get one of the above phones you mentioned.

Thanks for the info, that's interesting to know. Out of interest, how many have you handled? Going by some comments on XDA and around the web regarding this issue, you'd think that the yellow tint was only on a handful of handsets and an isolated quirk, not as I suspect and you seem to suggest, a common trait of the N4.

Well,
I ordered three of them, all screens looked identical with the exact same issues: some yellowing at the bottom with a light bleed over the top edge (especially top right corner). I had to RMA 2 out of the 3 due to severe screen issues (screen flickering and dead pixels). Received 2 new units, screens have the exact same issue. I have 2 friends with N4s and their screens are like that too. It's almost not noticeable.

Does the light bleed appear like small blobs from the top edge?
My worst is the top left, about an inch in. Then there's another smaller blob nearer the right hand side. Little bit leakage top right and top left, but its worst along the actual taskbar.
I will take a picture tomorrow.

My first nexus 4 (rev 10) has perfect whites except the bottom of the screen would turn yellow after warming. All of the 4 RMA devices I've recieved (rev 11) don't have this issue EXCEPT all the rev 11s are calibrated horribly leading to the entire screen being yellower than my rev 10 unit. The screens are uniform, however, I just wish they calibrated the phones like they did with the rev 10.
The new rev 11s have a calibration problem while my rev 10 has a glue problem.
The new rev 11s also have a dimmer screen than my rev 10. I kinda just want them to send a perfect rev 10 to me.
Interesting because calibration issues affect the whole screen. If any part of the screen isn't the same "tint" as another part and its noticeable then this isn't something that can be fixed with calibration. Calibration can only save a uniformly "yellow" or "blue" tinted screen. To that end I wish mine was uniformly yellow. Mine is a rev 11 and I'm on my second day with it and hoping the bottom and left yellow tint fades soon and that it's just glue. I've tried Fauxclock and applying various screen tweaks with a previous similar phone and it helped somewhat but there's nothing can be done about unevenness in the tint really unless its glue and it dries.

I know there are other threads that discuss this topic (somewhat) but I wanted to post this separately because what I'm asking is very specific.
I've had about 8 separate Nexus devices from Google Play in the UK and every one of them has had the same issue:
The display has had a noticeably yellow but admittedly slight (possibly slightly brighter) tint on the bottom and left edges, while the right edge has been dull/dark.
This is specific because there are other and numerous reports of a yellow "tint" across the whole screen. This is not the whole screen, this is very clearly just the bottom third and left edge of the screen.
Some think that this is a "glue" issue that will resolve itself. Some think it won't get better. Some think that it's an issue they can live with. Some can't stand the lack of uniformity.
Well I can't stand the lack of uniformity because in my opinion, on a 4.7 inch screen, I find it distracting to be reading text on a solid background or white and the "white" or background colour changes as I read right to left or top to bottom. I consider a decent amount of uniformity to be a minimum requirement for devices which will be used in the way most of us use our phones and tablets. Manufacturers, seemingly, don't care at all except in the most extreme of cases. It looks like they are churning out whatever they can get away with. In all other aspects, the N4's screen is fantastic.
There's nothing anyone here can really do to help directly but it leads me to a question I haven't been able to find the answer to anywhere by Googling or searching other forums:
What is the cause of this lack of uniformity on these LCD panels? It seems to be LCD specific. As mentioned, some think it's "glue" but then others say not and in my experience the tint issues haven't gotten any better in the time I've had the devices that have passed through my hands.
I don't think it's the LED backlighting but could it be something to do with that?
Does anyone know, from a technical point of view why LCD panels are so prone to this issue with the yellow tints across *part* of the display. It's a very widespread thing as it's been noted on most of the iPhone range and a lot of other handsets too. Is there something inherently difficult for panel manufacturers (in the N4's case, LG) to do to make the panel evenly toned and lit? Surely it can't be that hard at this stage in the development of LCD tech once the manufacturing process is "calibrated" at the factory and underway? I assume these handsets are assembled by robots, not by hand. Is that right? Why is it so widespread? Is it a cost issue? Would I have a better chance of a quality panel by buying a more expensive handset? (Although I've seen many HTC One X's with the same problem - I did see one which was almost literally "perfect" in uniformity and brightness). I'd really appreciate any feedback on this. I know that because it's the "norm", sadly, the common response is to now "accept" the panels and handsets that are out there. There doesn't even seem to be a "higher end" manufacturer where high quality uniformity is more likely - or is there?
Anyone with a good/strong knowledge of LCD tech or the manufacturing process out there that can explain this?
Thanks!
***UPDATE***
I've now attached an illustration to show what I mean. ***It's exaggerated a bit*** to show the effect but illustrates the problem clearly.
Have you tried using a custom kernel to tweak the colors of the screen? The Nexus 4 is known for it's washed out colors so using a custom kernel like Trinity or Franco kernel allows you to tweak the color of the screen to your desire. Of course you will need an application to tweak the colors.
LG is known for light bleeding and or panel uniformity issues, I had to swap 4 LG tvs before I decided to go with Panasonic , my LG ips monitor that im typing on right now for my pc has light bleeding in some areas which results in low contrast. I saw about 13 different optimus g devices before I got the nexus 4 and the screens are beautiful with good contrast, punchy colors and good black levels with no light bleeding or weird tints while my nexus 4 has slight light bleeding right where the signal bar is located. I love this phone and its seems to get the " perfect " one you maybe have to swap a few times and to me the price kind of fits the quality of the phone but then I almost have enough spare cash to buy another one lol can't complain about that.

Thanks for the reply. I've heard elsewhere that LG specifically seems to have poor quality panel uniformity. I think LG panels are used by Apple who have had many, many reports of panel yellow "tint" issues on both their iPhone and iMac range. It seems to affect screens big or small. Having said that, HTC had similar problems and their panels were manufactured by Sony. I would *love* to know what's causing this or what is the reason for the yellow "tint" issue on part of the screen.

I have done all of that and with some success with all of the handsets I've had but because the tint affects only part of the screen in a sort of gradient - the calibration cannot fix it.
I'd much prefer a screen that had a yellow "tint" evenly across the whole screen then of course I could calibrate accordingly.

yellow patches is from the glue used in the optical lamination process, yellow tint is from the display calibration which is often used to reduce banding and gives more saturated/warm look to colors
if your device is affected by by visible yellow patches the only cure is to re-calibrate the display to reduce the effect and don't get the device too hot as it may increase it

Sorry but this is not what my OP is about. I do not have a uniform tint and therefore it cannot be to do with "calibration" of some sort unless I am mistaken. Neither do I have "patches" or "spots". This is very specifically about a gradient yellow "tint" that only affects part of the screen and trying to find out the technical reason(s) for its prevalence in a wide range of LCD screens used in mobile phones and of course the Nexus 4 in particular. I've updated my original post to include an illustration of the effect I'm asking about. Thanks!
I am pretty sure its a hardware fault and i assumed you tried to return it otherwise there is nothing else you can do so i suggested calibration to reduce the effect

There seem to be quite a few Note 4's being sold globally that suffer from serious screen coloring (color shifting) when watched from close to a normal viewing angle. To get an idea of the scale of this problem this topic contains a Poll.
This defect is most easily noted on a bright white screen (www.google.com, "Dead Pixel Test" app). Even at a slight angle (=20"-30" from dead straight) the screen will show a clear blue, green or red colored haze. The screen on a properly built Note 4 stays (close to) white, even at a wide angle.
Please let us know if your Note 4 suffers from this phenomena beyond a trivial degree or if it doesn't.
Also be aware to check for this defect BEFORE you root your Note 4, as Samsung will object or even prohibit you to exchange your device for a better model.

I don't think there is such a thing as a "normal" Note 4. Every AMOLED phone from Samsung varies from unit to unit. I remember finding exactly the same differences between two Galaxy S3s where one had a tint horizontally and the other had a tint when angled vertically. Interestingly the phones with the greatest colour shift are usually the ones that go brightest when looked straight on. Either Samsung is making these phones in multiple ways from multiple factory plants....or for whatever reason using different materials (such as polarising materials) in the top layers of the screen.
Although I didn't check the tint on a second Note 4 I tried, I did notice that mine was obviously brighter at all points on the brightness settngs bar!
Either way, while bad uniformity is definitely a defect....I think this off-axis viewing tint is not. If it was a defect, it would exist with Note 4 only and not all the Samsung phones I have seen to-date. BTW my Note 3 also tints when viewing at an angle but a bit less than the Note 4.

I never had this phenomena with my 5 previous Note or Galaxy S phones, nor on my Samsung Tab S 10.5's. I did have multitouch issues on my Note 3 and 2014 Note 10.1. Seeing the screen of the Note 4 is plenty bright I don't care too much for the "more brightness" bonus, if it were applicable here. I compared my unit to a random store unit and in direct comparison I much preferred the store model. The white screen already looked a bit 'off' on mine, and the store model did not have color shifting at all.

What are the chances of both my Note 3 and Note 4 having the same "fault" though? My Note 3 goes bluish off axis, my note 4 goes greenish. Both screens are still perfectly readable at any angle, and only colours that noticeably shift are white/grey. Orange still looks like orange, red still looks like red.

I think it depends on the amount of color shift. My Note 4 has a clear blue haze even when looking at it close to dead straight. I watched a snowboard movie/documentary and snow went definitely blue with only a shift of 20-30 degrees.
It's really good news to know that many devices don't have the blue tint when shifting! If mine has it I'll definitely send it to maintenance. I guess repairing is better as I can look at the device at their facility and not accept it if I don't like the results.

It is really hard to be sure we are all seeing or evaluating this the same way. For example, if I display a photo with many colours, I see no shift at any angle. White is the most obvious and you need "lots" of it like a www.google.com screen to see it. I would say I am fine for 20-30 degrees before it starts shifting. I think you may have been a bit unlucky in happening to choose a snowboard documentary rather than Iron Man 3 or something like that etc! Then you might not have noticed it
I voted "No" because the poll asks whether the screen color changes at a "SLIGHT" angle. While mine does not, at a larger angle the screen does show blue tinge that increases with the angle.
I have this too, its normal?
I have the same "issue" actually it was the first thing I realized when I turned on the phone for the first time. I haven't even realized it with my previous used galaxy S5
It's probably caused by some coating layer. Nothing we can do about it, doesn't distract me much in a phone anyway. The screen is lovely apart from that, the black level made me almost cry when I compared it to my LCD TV. I so want an OLED TV now. Shame they are so expensive.
Mine does this:
https://www.youtube.com/watch?v=aVrm73sAnUs
Is this a faulty display or is it just the way this display works?
There are several factors involved,
- Amount of Oleophobic Coating which distorts the actual colors discernible by the viewer
- The Digitizer
- The Corning Gorilla Glass
- And the amount of bonding used to keep the AMOLED display adhered to its bottom layer (Remember: Organic by Nature).

It is not repearable by software or external means. Well, maybe a heater could do something, but I am not gonna try.
I sold my Note 4 and now have the Note Edge, which luckily has much less issue with color shifting.
While looking directly mine is red at the middle of the screen. While rotating, the red tint is appearing at the top or bottom of the screen according the rotating direction. Also Bottom part of the screen is also less white than top.
Forgive my not reading the entire thread as it's late and time is an unusually precious commodity lately...
My screen does develop an extremely mild hint of a color shift at slight angles, but I don't notice it unless I look for it. However, at extreme angles (at which I never view the screen, like greater than 75 degrees away from dead-on perpendicular to the screen surface) I do see not only greenish/bluish (almost like a faded teal) but also a magentaish hue. I suspect in my case it's a result of the manufacturing and tempering processes of the glass. LCD panels exhibit something similar when viewed through polarized sunglass lenses, but this is not the same: LCD panels have a nearly random-blob appearance where on this Note 4 it appears in bands running along the vertical (when viewed in portrait orientation) axis of the screen. At worst, I can make it greenish on the left side and magentaish on the right by viewing at around 70-80 degrees off perpendicular, so admittedly I have to hold the phone in such an extreme position to see this that I don't consider it a defect per se.
HIH.
At the moment, I have both devices. Having used the S7 Edge since the release, yesterday I switched to the S7. In shifting back to the S7 Edge just now, I noticed the two device's displays are quite different.
The S7 clearly has more saturated colors and looks far brighter. The S7 Edge, in comparison, looks slightly more dull when side by side.
For reference, I tested both devices in the same conditions. That is to say the S7 and S7 Edge with automatic brightness disabled and pushed up to maximum manual brightness. Also I tested both in a darker room. For reference both were set to AMOLED Cinema.
Unfortunately even when the automatic brightness is turned back on, it's clear the S7 still looks more vibrant.
Can anyone explain what's going on here? Is it simply that the Edge looks like it has a lesser screen because of the larger size and thereby lower pixel density. Or is it something about the panels themselves and thus the S7 that I have now just happened to get a better panel than the Edge.
Any thoughts or answers would be appreciated.
Displaymate tested them and stated that they are practically identical in terms of performance: http://www.displaymate.com/Galaxy_S7_ShootOut_1.htm. Any chance you can test out against another Edge?

Actually no, unfortunately. Neither device has been released in Japan yet. Both of the ones I have are imported.
The thing is lot more complicated...
Each S7 Edge has different display quality! When you put 2 S7 Edge Side by Side and compare, you will see that the displays have different tint (mostly yellow), and more worse: a lot of the displays are not homogeneous. that means that one corner or side is brighter then the rest of the display.
i wrote a few threads regarding this, i also sent a message to displaymate (because they test "cherry-picked" devices, and do not mention this), see here: http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
basically i do think that the s7 screen is better, due to the Edge screen is P-AMOLED to be flexible! but the differences between otherwise identical devices are really huge!
i ordered my 5th device today, because all of them had flaws:
1st: display not good compared to second device
2nd: the device i use now. very good viewing angles and no tint, BUT: left side of display is darker then right side
3rd: display strong yellow tint
4th: display almost good, slight yellow tint. would take this, BUT: front cam takes blurry pictures compared to other devices...
5th: ordered today!
you may think i'm a hypocrite or have OCD, but it makes me mad that a 800EUR device has such flaws!!!
The s7 has more PPI due to smaller screen than edge

Or, you know, maybe you're looking for a flaw that's not there? It's a well known fact by now that a bend in a display, like the Edge, will have some shifts in brightness, tint and contrast, especially right in that bend! If this is something that annoys you, then I'd recommend you stick with flat panels from now on, because this won't be "fixed" for awhile. It's just the way it is.
Also, you do not have OCD.
"Obsessive-Compulsive Disorder (OCD) is a common, chronic and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that he or she feels the urge to repeat over and over."
If you turn the screen on and off 30 times before you can make a call, you have OCD. If you have to knock your door five times each time you come home, you have OCD. If you think the smartphone's screen is the wrong hue, that's not OCD, that's just being picky.

I think you're being a tad bit OCD. At the end of the day, the S7 might have a slightly better display than the S7E but the screen size and battery size make the S7E better for me personally. If you're looking for a slightly better looking display then maybe you'd be happier with the S7.

Thx for the medical and display-tech lecture, I'm a university lecturer (engineering and physics) myself!
1) Display quality: You did not read my post, or my linked thread regarding note4! The display of note4 was not curved, and had the same problems as all of samsungs amoled devices before: When you compare 10 devices side by side, you will see that each and every device has different screen tone, uniformity, ... About 2 out of 10 I would consider "good", all other have flaws such as a not uniform brightness distribution (one side of the screen is darker then the other side), or bad viewing angles.
this is NOT a problem which every device has, as I always found one device in the past which was "OK" after exchanging a few times.
same happened last week and today: last week i got a device with a really nice screen, but the front cam took blurry pictures compared to the other S7E devices I have in front of me. this can be easily reproduced, so the cam or lens has a problem the other devices do not have.
the device i got today has the best screen so far (good and even white distribution, good viewing angles), the front cam is ok (a bit less sharp pictures then my reference device, but WAY sharper as from the last weeks device), but there is a scuff on the top metal frame of the display, between the glass and the metal. this is no dust particle, it is a real scuff. :| i will test the rear-cam as well, if it is ok i will stay with this device, as the scuff is not nice, but a minor issue compared to the display faults of the other devices.
also, i showed the different displays of all my S7E devices to friends and colleagues (because they thought i'm crazy because of my exchanges), and all of them see the display faults as well. you need to have devices for comparison, then you will notice how bad some screens are compared to others!
so no need to go for an other device as the S7E, because there ARE good ones existing. but you have to be lucky to get one...
on the OCD: this was half ironic, because i know that OCD really is.

I did.... not read that Note 4 thread, and I did (clearly not) understand what you said (blame the beers I had), but alright, I do understand what you're saying now, and yeah, there is a slight difference in each panel, and some will get a slightly better panel than the other one. That happens with every screen out there, including LCDs, and viewing angles are also something that gets affected, but I have the impression that this is more of an issue with LCDs.
I would keep swapping it until I got a good panel, so keep doing what you're doing until you get tired or hit the jackpot. The screen is rated as the best smartphone screen ever, so I promise you it should look amazing. The issues you're experiencing is very common though, and must be somewhat expected when we are early adopters. These are typical issues that Samsung will weed out with time.
I saw a strange think on S7E: the 2 sides of the screen have grey shadow area if you looking at it in a dark room with low brightness of course...is that normal?
My is perfect :sly:

I saw other phones and talked to other S7E owners, and they see this grey halo too, when the brightness is low and the environment really dark. Do you think that it is a problem of my screen?
Today when I was holding both my Nexus 6P and Galaxy S7 Edge side by side, I noticed the 6P whites looked significantly more yellowy compared to the S7. I know that the displays weren't that different when I first got them. So I confirmed my S7 was still on the default display settings and the 6P doesn't have any color settings (besides the sRGB color switch in developer settings, which was off). So I knew something was wrong.
I opened a blank Google Doc on both phones. So it was completely fair using the same app to compare. Then just by chance I noticed when the black nav bar at the bottom was recessed, the display was a good bit whiter at that bottom stip than the rest of the display. I looked even closer and noticed the nav buttons were slightly burned in too.
The nav buttons slightly burned in did not really surprise me much and does not bother me much. Especially since its barely noticeable right now and the nav bar covers it 90% of the time. My main concern and disappointment is that this proved my display has Yellowed over only about 1 year of use. I've had my 6P since November 2015 release, but only used it about 9-11 months since I use my S7 edge instead sometimes too.
Is anyone else with a 1+ year old 6P having their display getting yellowish too? Im trying to figure out if this yellowish tint is just just bad luck with mine, or if its happening to all 6P's.
See attached image. Its kind of hard to make out in the picture but it shows the whiter strip at the bottom.
I see the strip at the bottom, but I haven't had any issues myself with any sort of yellowing or discoloration of the screen. I've had my phone about a year now and bought from a seller on Craigslist.

Yep mine is significantly more yellow then when i first got it. Its burn in. (or as im to understand the screen is wearing out or something like that) My nav bar icons and status bar icons are burned in. And the burned in icons are the same color as my yellow screen.

Thanks! I did some research and i can find people complaining about the yellowish with in a couple months getting the phone or right when they got the phone. But nothing from people reporting it getting more yellow over time.
It seems like these amoled displays huawei used aren't very good quality if they can't maintain their color for at least 2 years. Of course the nav button burn in is expected, but having the color change yellowish after only several months of use is unacceptable. If my Samsung amoled display maintains its color for about 2 years (its almost been a year so far), then that proves its not exactly a fault of the amoled technology, but proves Huawei had a poor quality display.
If my Samsung display doesn't last 2 years either, then I might go for IPS display next time. The color accuracy has gotten a lot bettrr on them over the past years and not as washed out in color as they used to be.

I don't have any problem with my N6P display, at least not moticeable. I also use an immersive mod, so no navbar/notification bar burn in. Also using black theme. Don't know it it helps... I had the problem on my Galaxy SII a long time ago. I've already seen a lot of people complaining about the issue and if you Google it, it's a common issue with AMOLED.
Also the N6P display is a Samsung. Maybe they sold Huawei a defective serie?
Are you completely stock?
It happens on every screen regardless of the tech. Some just get it quicker than others depending on usage.
This screen does look more yellow then my iPhone or my s6 did, but it's still a great screen imo
