On my 4th Nexus 7 and backlight bleed.... - Nexus 7 (2013) General

So I exchanged my first Nexus 7 because 1 dead pixel (build date 2013.10), got my second one with horrible multitouch problems and several dead pixels (build date 2013.08), my third one with multitouch problems and 8 dead pixels! and dust under the screen (build date 2013.09) and now on my 4th one (build date 2013.10).
- no multitouch problems;
- hardware is perfect, no dust under screen, no scratches, nothing (the first nexus also had some dust under the front facing camera);
- no dead pixels;
- but...it has in my opinion al lot of screen bleeding
Now, the question is, should I return this unit, I have made some pics in the dark with 100% brightness, what do you guys think of it?
edit: the bleeding is always seen on a black background during the evening (when its dark with normal house lights on), not so much in daylight. However the bleeding is seen even on 20% or 30% brightness, only if I turn on the automatic brightness things get a little better and the bleeding is minimised to the point that I am less bothered by it. Ooh and when I look at it from a different (a rather extreme) angle it also changes, so I guess it is some sort of glow

Oh....c`mon dude...if you want perfect blacks buy something with AMOLED display.I had that backlight bleeding on my Nexus 4,LG G2,Acer CloudMobile and even on Nexus 7(2013).I think this is normal for IPS displays.It`s just my opinion.But i`ve never seen a IPS screen wich renders perfect blacks like AMOLED.On my Nexus 7(2013) the white spot on the black is not that evident.I will make some pictures when I get home and post them here just for comparison with your pictures.

Somehow I don't believe what you're saying.
That much light bleed on 30% brightness? I call bull**** sorry to say.
It's on 100% brightness and it's on a black screen, what the hell did you expected? It's native to IPS screens so either live with it or guy buy a Samsung Tab 7.3 for 250€ with it's amazing hardware and screen. NOT.

Like I said in the first post "I have made some pics in the dark with 100% brightness, what do you guys think of it?"
The light bleed is indeed visible on 20% or 30% brightness, but of course less than with a 100% brightness. The problem is, everything besides auto-brightness makes it visible. Normally on my other android devices, I turn off auto brightness and leave the brightness on about 25% with the standard widget (with the half moon sign). But on my nexus, I can't do that. The statusbar is always washed out.
The first 3 units didn't have this much bleed, they had very little, not worth mentioning. Also, I am very aware of the fact what I can expect with IPS displays, AMOLED displays (like my galaxy nexus), TN displays (like in my Macbook) and PVA displays (like on my dell 2408fwp). The thing is, this light bleed on my nexus is very obvious and beyond normal. If the light bleed was not so visible under say 60%, I wouldn't care one bit.
The thing is I am very disappointed with the quality of the hardware. I have never in my life returned a gadget more than twice. Normally, if the first one wasn't good, the second one is almost certain perfect. Don't get me wrong, the nexus 7 is a awesome device! But these faulty units ruin it for me.

Maybe bad batch? Mine made in August 2013, nothing wrong

I don't want to sound arrogant or an ass, but I'll tell you what the problem with these threads is(which are alot believe me), light bleed annoyance/any of the other known issues is a personal thing.
And, coming here asking for advice is worthless because it's subjective and won't resolve anything. Everything about your device is up to you or whoever else opens a thread. If you find it bothering, go trade it until you get a unit working fine. Afterall, you payed and you have the right to have a fully working device. If it doesn't bother you that much, don't trade but and don't open a thread about it.
It won't change a thing, whatever people tell you it won't mater.
Good luck.

Hey, I had had 3 Nexus 7 2013s and all of them had light bleed. Even my iPhone 5 (bring on the hate bc i honestly hate my iPhone) has mild light bleed at 100% brightness on boot animation. My father had a Galaxy Note and he was used to flawless blacks and when he got an Xperia SP, he watches badminton matches at night and on loading screens, light leaked out from the sides. He went to Sony but they dismissed the problem

You have to decide how much it bothers you. It's much more than mine (100% bright), but my touch screen isn't what I'd like (like my N5 or even my old Toshiba Thrive).
EDIT: This pic taken of the N7 with my N5 should show better. It is a black background with 100% brightness. Only slight bit of bleed across the top.

You aren't supposed to take a screenshot. You're supposed to put your phone in a dark room and display a fully black pic at 100% brightness

That was a screenshot of Backlight Bleed test at 100% brightness in a darkroom. I understand that maybe the "screenshot" concept prevented light bleed from showing although both look the same. I'll fix it and re-up or remove it.

Do all the newer/newish Epics/Galaxies have yellow/yellowish displays?

I just got an Epic.
Reading several threads across the Galaxy line, there is apparently a variation in screen color temperatures. From my readings, I see a pattern where perhaps the newer/replacement units have yellower screens. At the same time, those newer units also get darker in auto brightness mode than the older units.
From my own observation, the color temp gets cooler as the brightness increases.
Is it possible that Samsung tweaked the auto brightness so that the phone now gets darker in order to save the battery? So perhaps the different color temp observed are a function of how bright the screen is?
I don't care for the yellowish screen on my new Epic. I like a cooler/colder screen. Comparing the Epic next to my LCD Evo and Touch Pro 2, it is outright yellow. Comparing the 3 phones next to my Nexus One, the N1's screen looks pink. (I can post some pics tomorrow).
Bottom line, I'm trying to decide if I should try to return/exchange the phone for another and hope for the best. I read that there are some potential software solutions out of XDA, but I prefer to have a phone that is natively "cold".
Any input would be great.
Thanks.
Mine's pretty yellow. :-( In brighter light, it is not a problem. Darker screen is the result of a software update. Got mine on launch day.

Thanks for the information. Before the software update, when the screen didn't get as dark, did it appear less yellow at the [pre-update] low brightness?
In other words, does the screen now look more yellow than ever since the update and darker screen?
Cheers.
I got my Epic on Oct 1st, and I haven't noticed this yellowish at all, but maybe I need to do a thorough side by side with an older model?
Did you get any pics to post up yet? I'm interested to see this

Just as yellow as always. Post-update, the screen dims more. At this point, it appears yellower. My Captivate also now dims more, post-update, and seems bluer at dimmest setting.

The only time I've had problems with my screen was when my phone had gotten damage from water. I'm on my 2nd epic and this one doesn't have any yellowish tints. Only about a week old now.
Sent from my SPH-D700 using XDA App
I picked up my Epic on 9/29 and don't see any yellow tint at all. I'm not an expert here but I think I would notice a tint like that. My blacks are very clear and dark also. I did notice that it seemed to run on auto brightness a little darker than it had...that was probably the D-118 update after I had it for only a few days.
I will follow this thread and see where it goes.
I don't think the screen color variation is based on release date. I have two of them since 8/30. One of them has a yellowish tint compared to the other. They both have the same DI18 update.
It seems like a coin-toss what screen color comes. I wish we have a tool that would allow easy color temperature adjustment.
I read a thread about a way using a modified kernel, but it would be nice to have an .apk that works (even if it requires root).
I got one on launch day that had more of a blue tint to it. I got another one last week that was a refurb, and it definitely is more yellow.
Weird. I just got mine today and it's very cool (read: blue) compared to my Evo... being a photo guy, this drives me nuts. I prefer warmer diplays.
Sent from my SPH-D700 using XDA App
I have one of the cooler screens, and I kinda like it.
My thoughts:
1) Samsung is trying to extend the life of the blue oLEDs by altering the color temperature of screens. Since this seems to be happening independently of ROM version, it's probably something they're doing with firmware.
2) (IMO More Likely) The screens on different phones came from different assembly lines or different production runs, and have a slight variance in color production. The production date of the phone wouldn't necessarily matter in this case.
The only project I know that deals with the color temperature of the screen is voodoo:
http://project-voodoo.org/color
I currently have it running on my ROM. It adds a new "very low" brightness setting a the bottom that's much dimmer than even the lowest one available in DI18. (Note: it doesn't interpolate levels between them, either. Meaning there is a big jump in brightness from the voodoo lowest level to the DI18 lowest level, which is the next "notch" up on the slider.) It also adds a brightness level at the very highest brightness, which noticeably makes the display warmer. (The highest and next-to-highest brightness notches are the same brightness, the difference being the highest one is warmer.) At this point of its development, it's really of no use if you want to make your screen warmer at all brightness levels.
At any rate, the project leads me to believe that, with further development, we could have an app that allows us to freely change all the color settings for the display for all brightness levels, save them to profiles, etc.
The idea of the screen getting warmer as you decrease its brightness might be a natural phenomena, or just perceptual. In my experience, colors usually seem warmer as you decrease the intensity of the light. This is even true of light on a physical object.
My screen looks awesome. No yellowing or anything. I wonder if there is a difference based on who made the screen for that particular Galaxy S phone? I remember reading an article when all the Galaxy S phones started rolling out saying that Samsung was having trouble with the manufacturing of the AMOLED screens. Perhaps they started cutting corners.
However, there also seems to be issues with auto-brightness, etc...I have that disabled on my phone and the brightness set on its lowest setting (which is plenty bright for me and all my viewing needs) which may be the difference? But, I have cranked it up from time to time just to show others and I still don't notice any yellowing.
Is there a specific test image or something where one could view that would show/exaggerate the effect people are talking about? I would be curious to see...
Thanks for the great input and information.

Here is a quick picture taken by a Touch Pro 1. Sorry about the quality. I can try to take better ones if there is interest.
From left to right - Evo, Epic, Nexus 1, Touch Pro 2. All with auto-brightness on.
In real life:
The Evo looks whiter (cooler)
The Epic looks much yellower (warmer, almost greenish)
The N1 doesn't look as pink as it appears, but looks the darkest
The Touch Pro 2 looks the whitest (coolest)
To my eyes, the Evo/Touch Pro 2 looks good. Although the picture shows the Epic looking pleasant and only slightly warmer, the white elements (clouds in wallpaper, browser backgrounds etc.) look yellow/green.
Edit: Notice the Menu, Home, Back, Search menu LEDs look whiter than the screen. See the contrast between the two makes the screen look yellower.
I've owned 3 Epics since launch day. First one had a good screen, 2nd one had a yellow tint, 3rd was perfect.
The build dates of the first 2 were 10.08 and my current one is 10.09.

By perfect, do you mean that it is not yellowish? It's interesting that the first two phones with the same build date has two different color screens...
The Epic I have has a 10.10 build date. It's yellow at dimmed levels and color temp gets cooler as it brightens up.

[Q] how much light bleed is too much?

I have some light bleed in both of the bottom corners. They are clearly visible on 100% brightness in a completely dark room while displaying a black image, however when the brightness is set to 0% I can only just make out where the bleed occurs. It's almost a yellowish hue and spurts off the edge of the display a few millimeters. Now with auto-brightness on and just using my device it doesn't really jump out to and when showing it to others they couldn't even spot it when I told them to look for it. I just wondered if others were having this issue and if it was worth it for me to try to RMA another one. Funny thing is I just turned on my old 7 inch galaxy tab 2 and it has some bleed, but its not nearly as noticeable. As someone was saying I just wonder if a larger percentage of these have light bleed then those that don't.

IMO, if you have to sit in a pitch black room and crank the brightness up to 100%, then I would definitely keep it."Too much" is hard to define; many ppl here will RMA until they find a "perfect" unit.
I've heard ppl say that not all devices have bleeding, but in a world of mass produced products, screen bleed is just a side effect of consumer demand.
My family uses both Apple and Google/Android products. This includes 1st gen iPad & 1st gen iPad 2, and 3 android tablets made by HP, Asus, and now, Google. They ALL have screen bleeding. (HP being the worst of the five)

True, and like you said a lot of them may have it. What I don't want to do is order another and have it be worse. I just wondered if it was common and if those that can make it out in everyday use are going to return it. With that said mine can't be too bad as it isn't visible on any other color than black.

I would keep it sounds like minor light bleeding for you. It's normal to have some light bleed anyways. I've had it on all my devices (IconiaA500, Galaxy tab 10.1, Prime, Infinity, Note 10.1). If its visible for me even during the day then it would bother me and I would replace it.

It is visible during the day with auto brightness on, but it's only because of the black bar along the bottom. It is only just visible in lowish light with auto brightness on, so I don't know if I should send it back. The only thing I don't want to do is send it back and get one that has it worse.

does anyone not have light bleed?

Hi. I read a lot of light bleed issues.
Are there any without light bleed?
Is there a poll on this. I am curious about the ratio.
I am getting my nexus 10 today and will not be able to use it till the 25th.
I hope I wont be RMAing it on the 26th...
Thanks joe
I have purchased 3 N10s so far for myself, family member and a friend. All were purchased with 1 week or so gap and all 3 have backlight bleed to varying degree. Unless you have really bad bleed which is discoloured like too yellow, stick with what you have as there is every chance you might get worse piece.
While backlight bleed does not bother you most of the times, yellow one is whole different story.

Agree. My first one was the best, it was a relatively small bleed and it was white. I should have kept it. My 2 other replacements were yellow and that sucks. I am hoping my next replacement will be either no bleed or very small white bleed.
I haven't done a full-on light bleed test in a dark room yet, but I have not noticed any on my N10. So, if I have any on my screen, it's very mild.
I just received my N10 yesterday, so it's possible they've improved more recent ones...
I ordered mine the day it was released and I don't notice any at all either. I have not run a full test on it because if I don't see it (even when trying to find it) under normal usage conditions I do not really care if a test says I have it or not. Screen looks perfect to me so I am not really looking for reasons to not like it.
Would be good if you post on this thread to specify what is your BRIGHTNESS setting (full, auto, %, etc)
I have no light bleed on mine bought day of release.

The same. Fantastic tablet and although some people do seem to genuinely have a defective screen, some people are totally nitpicking and blowing the whole thing out of proportion. If your screen is totally black you're not actually using your tablet for anything so these tests people are running are pretty unrealistic.

Completely agree with your comment. Some might have true issues. I can see that mine has a slight bleed on the right side but there will never be a time where I sit in a completely dark room and stare at a black screen. Even at full brightness the slight bleed does not affect the look of my tablet in any way. It's an all around beautiful device!
None i've noticed in normal use but also havent gone searching for it. If the only way you can see the light bleed is when the screen is completely black then who cares. If the screen is on and completely black all the time then you have others problems besides light bleed.

If it looks good while I'm using it and I have no issues I'm OK with that!!

I did a bit more experimenting today. If I bring up a full-screen black image in a dark room with screen brightness at 100%, I can see some minimal light bleed in the lower two corners. My guess is, as others have said, that this is just going to be a given with these types of screens. I also noticed:
As soon as I set my screen brightness to auto, while still in a dark room with a full-screen black image, the light bleed was totally unnoticeable.
As soon as I turned on the lights in the room, with screen brightness still at 100% and a full-screen black image, the light bleed was totally unnoticeable.
So, for me at least, light bleed is only noticeable if I intentionally make it happen. Having the screen set to max brightness while in a totally dark room and a mostly black picture on screen is a pretty unlikely scenario in the real world. In normal usage I've never notice the light bleed, and I doubt I ever will.
I've been using my N10 since it was first released and the screen is perfect. Do you need unnatural or unusual conditions to detect light bleed?

[Q] Do you have Light bleed on the bottom of your Screen?

Do you have the well described light bleed on the bottom of your screen (7 brighter spots) at low brightness?
Whether you do or do not I am curious to know what your serial number date is.
I.e. are the 1st 3 digits 311 or 312.....
Someone suggested this was fixed on newer batches of these tablets and am curious if the newer serial numbers are showing the same issue.
311, got bleed. Don't care tho.

Yes but only with a white background at that edge and when the tablet is at less than 20% brightness. If it is a darker background or the tablet is above 20% brightness I have no bleed that I can see. In fact, I never noticed it in regular use until I looked for it in order to reply to your thread. So obviously it does not bother me. SN 311.

Thanks. My purpose is not to get people bothered. I am more thing to establish 2 things. First that unlike light bleed which is random this its a near universallyrics described flaw out limitation of this device and going and returning it for am exchange is likely fruitless. Keep it if you like it or move on. I have chosen to keep mine.
Secondly to seeif there is a pattern to those that claim not you'll have this issue. One person in another post started his first twist had it but the replacement with a newer serial number did not.

Part of the reason I never noticed it is that I have my on-screen buttons as black so any bleed would never be visible for me in portrait mode. Also, the only time I ever have my brightness that low is at night when reading my kindle app in bed and I use the white text on black background for that so bleed would also never show up in that situation.

Similar situating though sometimes might surf or watch a video in bed at low brightness and then was surprised to see it

309 Here and yes I have the bleed but it doesn't bother me because most of the time my black nav buttons are there. Only really noticeable when you have only white.
The only bleed I have is when when brightness is jacked up and the background is dark. It goes a bit lighter in the corner but no worse than my nexus 7.

That is traditional light bleed. Please state what serial number you have

So minor i can barely see when trying in a dark room with any brightness. Less light bleed or inconformaty than any other tab i have owned.
I have a black 309 from best buy.

So what this means, is that the lack of the light bleed at the bottom of the screen that so many of us have is not necessarily related to do the month of manufacture. Somebody had suggested that models with serial 312 and higher were made sense that have not exhibited the same problem.
One thing I have noticed, is that I can lower the brightness on this tablet to a much lower level than any other smartphone or tablet. It is possible that is why we see those 7 lights at the bottom. It probably has to do with the fact that the overall screen brightness is so low that they become visible. Ordinarily on a different tablet it probably doesn't reach brightness level that low where more artifacts in the screen becomes viewable

This is a great thread and to tell you the truth if you havent began this one i would very soon began one similar. Here is my observations:
My first one was with 7 bright lights on the bottom vissible on white screen(do you tests with an apk thats free from Google playstore called "Backlight bleed apk", its free) from a 35% brightness and lower. It was annoying and second,much more important,for the money i gave to LG i want the product to be of high quality and tested by their technicians very thoughtfully before launching it. So i return it as a DOA. The second one had no 7 bright spots on the bottom but it had a yellow line on the top(under the Lg sign) that was very obvious with a white background (from 60% brightness and up). This one went also back as a DOA. The third one has again 7 bright spots on the bottom but its noticeable with 20% and below. All 3 devices are 311. Its quite a shame that this device with such good specs has such bad screen problems. I thing LG had a wonderfull idea with this tab but hurried to get it to the market.
Does someone with 312 have simmilar problems?

Does anyone here with the lightbleed problem also have a problem with the screen seeming loose? When I push on my screen I can hear some creaking.

Ingesting and unrelated.
Here are my chronicles:
1st G pad: white 310 serial. Had both regular and 7 light bleed. Had not readabout this issue before returned it.
2nd G pad: Black don't recall serial. Good build quality no light bleed but 7 light issue. Now aware this is a common problem. Decide to exchange and go to best buy inspect 2 others (sales person let me setup 3 tablets and look best I could for issues. All 3 had the 7 light thing so figured this must just be a characteristic of the lcd they use in this tablet. So took home
3rd Gpad white w 11 build which in store I thought was better than the 2nd for the 7 light issue.
For Home was wrong and based on what I have read and my assessment I was resigned to the fact that they would all be this way and was going to keep. At this point I stated this thread after reading about some people who did not have this issue, one of them having a December or 312 build which I have been unable to find anywhere.
The build quality was bad in this replacement however. The edges of the tablet were sharp with a seam the others didn't have. Less than 1 day later the bottom right of the tablet must have been lose as depending on how I gripped it, it would creak and pop as if the plastic was coming off and snapping back.
At this point I decided I would return as a defect and got
G pad 4: white 310 build.
Was similar to second tab in buildwith almost no light bleed but had the 7 light issueand also felt the lower right part of screen at edge of bezel felt it had some give. I am now fed up and neuroticabout all this add I am in vacation in the USA and we don't yet have these in Canada.
Wanted to settle it. Found one other best but that head in store stock and it was rainy so I said last try to get at least one with only the 7 light issue.
Picked up a black one. 310 serial.
Took it home knowing that I'd it was no good I would say screw it and get ipad mini.
This one is nearly perfect.
Even at 0 the 7 lights are almost invisible. I have to look for them as I know they should be there. There is just a bit of traditional light bleed visible at 100% brightness in a dark room and in dark room I am rarely above 40%. Build quality is great and screen doesn't have any significant yellow cast.
I love it!!!!
From all my craziness I have discovered a few things that might explain the issues with this tablet.
1) 7light issue is there in every tablet. It is the way the lcd back lights work. The reason I and others likely have a tablet that doesn't exhibit it is due to something else. Brightness of the screen. By this I mean that all the tablets that have the 7 light issue can be dimmed incredibly low at the 0 setting.
Much lower than an ipad other tablet or my Samsung note 3.
My best screen seems noticeably brighter at lowest brightness. When reading an ebook at lowest brightness with white wiring on Black background the text is brighter in this one. So it could be that my 0 brightness calibration of the screen is closer to a 20 on one of the screens exhibiting the 7 light issue.
2) White tablet shows fewer finer prints if that is an issue but the metal black back is sweet!
3)With the voice Siri like app you can have option to enable or disable it listening for a hot word to activate it. With mine turned off my standby battery life is great even with 3 email accounts (1a push exchange account) going. We are taking 1% every 4-6 hours. This is much better than every tablet I have hadand my phone. This in spite of wifi on during sleep.
4) In spite of my issues of which in retrospect I would have been fine with my first 2 tablets and my current one I love this tablet.
It is a much better size than the lost nexus 7 2013 it replaced. Having expandable storage Ada much needed versatility. It does not win in any one category like an ipad or Nexus might but it hits all my desires from stereo speakersto God look to nice screen to great ergonomics.

311, have the light bleed. thought of exchanging it because it somewhat bothers me when I'm web surfing at night in landscape, but I figured out it doesn't worth the effort becuae probably most of the other slates have this problem too. I was right.
I think we should all be a little bit less perfectionists about our tablet, and give more thought to the good things at the tablet + focus on more important issues in our lives (At least I know I should )
I would like to buy G Pad but before ordering it in online store (Poland) I sent them a message asking for checking some G Pads randomly. The result is shocking: first 10 G Pads have light bleed at the bottom of the screen. After that they decided to check all tablets in stock. It turned out that all of them (> 50) have light bleed at the bottom of the screen. Product manager told me that they will contact with distributor of LG in Poland requesting clarification on that issue and they want to return all G Pads and replace them with good ones.
Will let you know how things will go on.

I have stud I think this is less a defect and more a characteristic of this screen technology. Based on the unit I now which does not have it I can say that mine does not get as dim at 0 percent brightness. Could be like with all LCD tech that below a certain brightness things like this are visible. It is a trade off in that you are getting a screen that can go dimmer but with those lights visible.

I'm on S/N 311 and I got no bleed at the bottom, but at higher brightness I got a pretty serious bleed at the top left corner, that's left of the LG Logo. I don't notice it normally but when I use the tablet in landscape that spot is covered by the black software key bar, making it stand somewhat out. I'm not gonna get it replaced, I played that game with my SGS-II back in 2011, you ARE going to find something else on the new unit cause you'll have gone in nitpicky mode.
Besides at this price, which is one third of what I paid for my Note 3 on launch day, you can allow a tiny few beauty marks.
Exchanged a black gpad because of a 0.5 inch yellow line at the top of the screen. Don't know the serial number unfortunately.
Got a 312 now as replacement. This has the light bleed at the bottom as well. But I have not seen any of the other issues like the blue line or the issue above. The bleed is noticable, but I might keep it anyway because most of the time i use it in portrait at high brightness....

Fix uneven/yellow screen with intentional burn-in

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.
Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.
I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.
I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.
Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.
Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.
I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)
You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Hey,
Seriously, a refurbished device just after a few days? Like you had it for 10 months, lol? Is it Huawei?
Escalate the case to a supervisor and don't give up until you get a "proper" new phone!
Good luck...
