[Q] Poor screen uniformity (+yellow tint) - brightness and colour - Feedback Please!

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.

Screen problems

Hi, so basically, ive had two nexus 6ps, both have had one side of the display darker than the other, but my second nexus display is kind of worse than the first, and even on my friends nexus that looks better, even his still isnt uniform, and one side is slightly darker,is there any solution maybe through changing colors? im on stock with elemental kernel?

Need a few questions answered before i decide to buy

Hello, sorry for the really long post.
my current phone is the nexus 6 and i plan to upgrade to either the nexus 6p or moto x in the next week or so but first i have some questions.
Firstly i have had my nexus 6 for almost a year and for the first few weeks i had 5 different devices as the nav buttons and status bar kept burning in to the screen after a few days or sometimes even a day of use with the brightness at about a third. After the 5th phone i just accepted the burn in and kept it but i was wondering if any of you have had burn in on the 6p. I know amoled screens get burn in over time but im hoping the 6p has a better screen and less chance of burn in than the 6.
Also does the screen go as bright as the 6? I checked in the store at a demo version and it didnt seem as bright at max brightness. But it did still have that yellow tint to the whites and pinkish tint when the brightness is at its lowest. I was hoping that would be fixed in this new phone but its not a big deal as i have gotten used to it from my nexus 6.
On to the back and i was wondering if it scratches easy and if so what would be the best colour to get so that the scratches are the least noticeable? Also i looked at another display model from a different store which wasn't a real phone just one of the fake ones you see and the N and E from the nexus logo on the back was rubbing off. Is this the case with the real phones or was it just because the fake phone in the store was made different.
Thank you

1. Too early to tell about burn in.
2. IDK, I didn't have the 6. It's bright enough to need to turn down.
3. I have mine in a case. If you are worried about scratches, then get the plain aluminum.

Do you have any problems with screen colour like pinkish or yellowish tints?

Yellow Display

hello all,
yesterday i got my 6P. next to my XPERIA Z3C its very yellow. okay on this photo it looks extreme in reality its not so extreme. i write an email to the seller and they told me they know this problem and it will go away after about 1 week. can anyone confirm this?
** sorry for my bad english
greetings, denis

If you select use sRGB in the developers options, it should fix it.

i already tried that but it turns always off on reboot. and i think normally it should work without using the sRGB function...

I'm not really sure then. I don't really notice it on mine if it is yellow.

I understand your frustration. I have a 6p and also a Z3 and when I first compared them the difference was obvious.
The problem is that that'll happen whenever you compare an LCD screen with an AMOLED screen, LCD will always have "whiter whites". The degree will vary depending on the model though.
Anyway, if I didn't also use my Z3 then I'm sure after a few days my eyes would've gotten used to the color calibration, but since I do use it, it was driving me absolutely crazy.
After some research I saw that the best solution to my problem was to install a custom kernel. It's a fairly easy process and there are several very stable kernels out there for the 6p. And with that you can tweak the screen color calibration. After this, I couldn't be happier, my whites actually look white and not yellowish

At least yours is uniform. I'm on my 2nd 6P and this one has uneven tint with the lower screen being yellow tinted and the upper seems normal and warm. Returned my first due to other issues.

I doubt it will go away within a week as the problem lies with the screen calibration... What i did was flash elementalx kernel and calibrated the screen. Now its much better.... Not as white as compared to my OPPO find 7 but way better then initial color...

This. I'm on muy eighth 6P because they've all had uneven yellow tinting to the display. I've gotten to a point now where I've realised that they're all going to have this problem, and I've just accepted that I'll stick with this one because replacing it could mean getting worse tint on the next one.

Yes this is what I'm afraid too. My first one had worse problems. Loose button which were rattling, imbalanced speakers and low volume output from 3.5 audio jack. I'm my country because we don't have Google Play Store for devices the replacement process is long and complicated. They agreed to exchange my first but they won't for a second unless it has a really serious problem. And yes I'm afraid I will get a way worse unit. At least the uneven tint is severe and I can live with it. Nexus and premium quality do not go together. Sure the 6P is better than previous Nexuses but it is also more expensive. I guess Samsung keeps the AAA quality AMOLED panels for themselves and sell to others the inferior ones. Before the 6P I had the S6 edge+ and the display and overall built quality was stellar. I just couldn't stand TouchWiz lag, the slow updates the nonexistent custom ROMs and the color shifting due to the edges. Google needs to improve QC of their Nexus. The 6P is a Russian roulette.

AMOLED Display Turning Yellowish on 6P

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
