Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:

I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.

Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.

The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.

I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.

Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.

Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!

As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>

I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?

Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.

so do you think it's a hardware issue, or maybe it will be gone??

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

This what you mean?
My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.

I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.

I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?

Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

Is my Screen defective Checklist

Yes I did just receive my Galaxy note.
Let's collect a step by step check list of all problems on defective screens.
I know that many of these artifacts are very subtle, and hard to detect unless you know what you are looking for, and is especially hard when you do not have something to compare to.
I hope you can prove a check list for all new users can check..

#1. Does the screen look good when you turn it on and look at it?
Yes: your screen is not defective.
No: your screen may be defective.
Really the only common "defects" that have been discussed here are a thread or two started by someone extra anal that happened to notice a common, but very slight artifact most likely related to the manufacturing process. When viewing a solid black background with brightness on high while in a pitch black room with your eyesight adjusted to the darkness, you can notice blotchy darker areas in the black. Every amoled I've had has had this "defect."
Some people also complain about the default color temperature and complain that it's more of a greenish tint. Every amoled phone I've had so far has had those same complainers, also.
If it looks good when you turn it on and use it, there's absolutely no reason to take a microscope to it looking high and low for defects. If you think yours is too greenish, return it and try another. Color temperatures and tints do differ from panel to panel. I had 3 nexus ones and each looked slightly different.

I have 30 days to return the product, If I have paid 540 euro I will not accept to have an defective screen...
How do I detect dead pixels the most easy way ?
is it to have a red background ???

I doubt very much if you have seen the individuals screen so what you say is based on guesswork. I have been using amoled screens for nearly 2 years and have never seen anything like this. A movie hired from the market was actually unwatchable on my note. I could not even make out what was on the screen at times. Even video and pictures taken by the onboard camera are very poor quality when viewed on the note. There is also an issue with banding and auto brightness changing randomly. Yours may be fine, mine was not.

I actually noticed these black blotches in a completely black room with a pure black screen YEARS ago on my Zune HD. I was freaked out then as I thought I had a bum one. After awhile I found every one had this issue. Since I don't stare at screens with nothing on them in the dark I didn't worry.
I wouldn't get too freaked out by the black splotches as long as it is decent and you don't have any bad pixels (bad pixels are a dealbreaker to me).

I do not believe a Note with a good screen exists

Please prove me wrong!
Anyone have any links to videos showing a Note rendering dark grays correctly?

watch the demovideo on your note.

The dozens of reviews which acknowledge how good the screen is proves you wrong.

Pfffff. Tests with Samsung handselected devices. Or do you think that Samsung will send defectiv devices to the testers?

The note I got from bell has no screen issues at all.

you can see down to one in gammatest??
no black clipping??

and: no dark blotches on a complete black picture in a dark room? (you have to see whole screen lightly lit (amoled cant go completely black), and let your eyes accommodate to the darkness!

SGN sucks on screen quality, its own spen scratch the "good" screen... really disappointed.

I honestly havent went out of my way to find any issues with the screen.
The videos I have watched all look awesome..I did notice on some dark images there was some banding or whatever its called but thats all I can tell..
I'm not that great with colors so I may not notice as much but it looks great to me so far.

Mine is fine with some tweaks. Primarily -40% contrast. I can see down to '2' on that test image. I also notice little or no blotchiness in dark videos any more, although I did before adjustment.
It's a software issue IMO.

I share the same sentiment as no one with a 'perfect screen' has shared it. The best I've seen is one w/o any black clipping what so ever since his gamma test result is similar to a Galaxy S2 but I do see a few visible horizontal lines on a grey screen. Its not perfect but its with in specifications aside from the lines.

To the unwise it may seem incorrect since they are only looking at the smaller picture and dont really have a clue on what this 'objective' test is for, let me give a real life example:
Using the Kindle application for reading ebooks gives you the option to use a black background now some screens have very visible blotches even if there is a text on the screen and they are become unoticeable when there is a text above them, this of course matters to someone who reads ebooks in their bedrooms w/o any external light source or to someone who watches movies like me. You see if we ask someone to open kindle and load up something and do this and do that, it makes the 'testing' more subjective rather than just test it in a pitch black room with a black image displayed.
These tests may sound silly to others but its the best way to get an objective result, remember people theres a difference between 'its not there' and 'i dont notice it with normal usage'.
here is an example that hopefully may enlighten you people with self proclaimed perfect screens so you may understand why its so difficult for others to accept such screen exists because with several replacements they havent seen one yet and people always claim that defects are the extreme minority, if its true then no one should need more than 2 replacements to get these perfect screens, correct?
It is also common for others to be dismissive of any screen related issues, you can be dismissive all you want provided you show an objective result. till then your screen is just as flawed as everyone else.

Are those dark rings one of the issues that everyone is complaining about? If so, I'll have to look at my unit, but I suppose I've just been extremely lucky. I have yet to notice any issues. That's not to say there aren't any issues with my device (possibly), if I look really hard, in very specific conditions

I do not have any black blotches or whatever.
One of the issue I have is the gray screen. It has somesort of texture on it but it's tolerable since it looks like a texturized wallpaper. No problems with playing videos at all, everything looks crisp and clear. So far I am enjoying it.
Also, another issue is the camera. When I am around those long florescent lights, there seems to be some wavy things on my screen. Even on video. I guess I got to avoid those lights in taking pictures. Haha.

That Image i used came from the Tab7.7 forums which shows the issue and practical scenario at the same time. Its an example of the darker blotches in blacks, not really the main issue on the Galaxy Note but one of the many possible yet rare issue.
On my end, my first screen had some blotches but they were not visible when I watch a movie or read an ebook from the kindle app, the 2nd screen I had did have a home button sized like blotch at the bottom which was visible when reading ebooks unless a text is close to it, in movies/shows it is only visible when the entire screen goes black.

Once again, I guess I have been extremely lucky with both my Note and my 7.7, because I have yet to notice any of these issues with either

Black clipping and banding = software. Therefore, irrelevant from a hardware perspective.
The splotches that you see in the most dark of conditions are the artifacts of the manufacturing process. Under normal 0% brightness (without using additional apps like screen adjuster) you will not be able to see these things assuming you've got a good screen.
The only things you need to look out for is color unevenness and brightness unevenness and in some cases, the manufacturing process is so prominent that it seeps into the normal brightness (0% and up range) and it is visible.
The fastest way to tell if there is something wrong is to turn off all auto-lcd power management, set the brightness to 0%, and to simply pull down the notification menu and view it in a dark place. That'll reveal most of the problems that you might find in a day to day situation. If you see nothing there and the screen looks crisp, don't bother looking for more. They will not appear in normal real-world situations.

No blotches on mine. Very happy with the quality. The color profile seems nicer than on my i9100. The only screen I had with noticeable blotches (only seen at full darkness) was on my T989.
So ya, very happy with my Note's screen. White International N7000

The witch hunt started with the original sgs and continues with the note.
Im on my second note plus a screen replacement and screens are flawless. Yes there is somme banding on all of amoled screens. Its partially software because running ics alpha build, most of the banding is gone.

Display Issues Thread

We can discuss display issues here. Here's my situation:
Let's be clear: MOST display have problems. My iMac I'm posting this from is tinted yellow on the left half and magenta toward the bottom right corner; my Nexus 7 2013 had edge light bleeding; 3 iPad minis retinas had edge yellowing; I returned and exchanged my way through 5 iPhones 5ses and 5 Nexus 5s before I found one without display problems; etc. But these faults are subtle enough that the general population isn't sensitive to them, or else they mostly don't care.
Sure enough, my Note 4 has display issues. I'm not sure if this is Mura Effect stuff or just bad quality control. Check it out below.

"lightbox_next": "Next",

}
The picture above doesn't do it justice, it's a lot more apparent when you've been using the actual display in real life for awhile. Also disregard the scan lines. But notice about 1/3 of the way from the top, there's a subtle horizontal line where the display below it is more gray, and more yellow above it. And if you divide the display diagonally from the bottom left to the top right, then the left half is tinted yellow compared to the right half, especially toward the upper left corner of the display. And the entire right edge of the display is tinted magenta, which is more apparent toward the bottom right.
Above I used the Note 4's Screen Write ability to document the imperfections as I see them.
Don't get me wrong, the display is nice. But I will likely have to flip through several devices until I end up with a good display. Are you guys noticing some Mura Effect problems, or other problems? Talk about them here.
PROTIP: to see the Mura Effect imperfections on your Note 4 display, grab this image and view it in a pitch black room and manually dim the display to the lowest level.

All I see is someone who is a perfectionist

So far I haven't had a display Issue. I keep at full brightness at all times.
Anyway, I know people are having issues and I am sorry you are too.
I got lucky I guess
From the BadAss Note 4

I dont notice this at all on my white note 4. Even if it so faint then the difference is neglible. Its not really worth the trouble going through 10 different devices just to get rid of this effect. But i turned off all lights and its night here so no outside lights and i see nothing at all wrong with my display. i also dont see anything wrong in your images either.

OP def has issues.
I see grey lines on the image that I'm not even sure is an artifact of the display or what you purposely have showing on the screen n I do see the slight greying 1/3 the way down, but again, what do you have displaying on the phone to represent this and how do you know that image itself isn't creating the artifacts, not the display?
No way YOU get that many lemons... either you're too picky or your method of testing is flawed.

The gray lines are from the camera, I edited the OP to reflect that. The image is just a plain white image, the same one i used to demonstrate display problems with the nexus 5 earlier this year. It's not that i get unlucky, it's that displays usually have problems. The apple store manager let me replace my 5s to get a good one because he acknowledged the edge yellowing and that colors were inconsistent even across the 10 display models. He told me outright that displays are calibrated within certain limits, and every display will appear differently, but that edge yellowing is an actual problem and he could see it after I pointed it out. I can't be blamed that most people aren't bothered by these problems, or that they're too insensitive to notice them. And again, the pictures don't do it justice...we're talking about a display you hold in front of your face live and stare at for hours daily.
On my current Note 4 what i mainly notice is that the gradient, where the yellow tint of the upper left gradually blends into the magenta of the bottom right. For me that's noticeable constantly. I can't make myself not see it, it's pretty apparent despite the image in the OP not showing it off well. As for the horizontal separation between the milky upper 1/3 and the gray lower 2/3, I'm only actually aware of that whenever i scroll, because eyes are made to notice contrast so it becomes apparent whenever my eyes are tracking something as it passes that border.

Nope. Perfect display here.

my problem.... and a big one, i cant stop staring at it. lol

Starting to have buyers remorse, tempted to consider a 6+ if stores dont have stock to exchange this for soon. Its so gross, this is all i see whenever im using my $830 phone with the "best mobile display ever" according to display mate:
Also, not necessarily a problem just something i noticed, this display gets SUPER bright in direct sunlight (its max brightness is only allowed on auto brightness, you cant set it there manually). That makes all colors super washed out, its weird, but so far not a problem. What im writing about here though is something I've never noticed on an lcd displays: whenthe note 4 SAMOLED is at this max brightness because youre viewing it in direct sunlight, if you use your finger to cast a shadow on the display, it makes this really bizarre inverted shadow effect. Try it out, its kinda crazy!

Hey am having tmobile send me new device because of this issue,for me it was really noticeable in landscape mode browsing Web at night once eyes start to adjust to screen brightness, I can see on mine were one side is whiter and the other a greyish purple hue.

My note 3 did not have this issue.

It's highly unlikely that you're going to score a unit with absolutely consistent white balance across the display. I haven't had an AMOLED screen that doesn't have it to some degree, and i've had many. Even my Note 4 has it, but it's very difficult to see unless you're really looking for it.
When I first got the S4 a couple years ago I got a unit that was so bad that when looking at the keyboard in landscape it was clearly 2 totally different colors on each side, but I exchanged and got one that was much, much better, but still not completely 100% even. So you might try an exchange if you can, but don't expect absolute perfection. Most displays on most devices will have some degree of imperfection if you look for it, whether it's white balance issues, back-light bleed, uneven brightness etc etc. An AMOLED panel is still likely to give you a better overall experience than a comparable LCD.
As many others have said in this forum, just try not to look too hard at the finest details ("mura" effect for example)...it's still mass produced hardware. If your screen is that noticeable though, exchange it.

I had this problem with my black note 4, my wife has the white one so it was clearly there when put side by side, tmobile said it was ok so i had to take her phone the next time and then they said it was bad. Something interesting, the white ones seem to not have this problem.

Yea got shipping info for new device today,should be here Monday,which ever one has least defect I'm gonna keep.

my gf has a white note 4 from vzw .. i have a black note 4 tmo.. the only thing i notice between our devices is that hers has a slight yellow tint but her display is a little brighter.. i have seen this with my old iphone's if i ever had to get a warranty replacement form apple .. the replacements always had a yellow tint but were brighter ..
so far no issues with my note 4 .. i got lucky this time around :good:

Lol.... I think I beat all of you. This happened a few hours ago while I was using Yelp and Google Maps to find breakfast. Needless to say I'm pretty upset right now, but thankfully I have my Note 2 still, so at least I have something to use until T-Mobile helps me out. I'll be going there in a few hours to talk to a rep to request a new unit. Hopefully they don't try and **** me because I bought in via T-Mobile's website versus in store or because I don't have Jump anymore.

Dude is that the way it looks ALL THE time? Dude GO WITH THE WHITE ONE. I know I am I have the charcoal black and seems to be a bigger problem with the black ones than white I went in to the tmobile store and they had a white and black one. The black one was the same as mine (bluish white/warm color) compared to the WHITE note 4 the white looked great. Sure the black seemed brighter but I think that's what hurt the device in the first place. Sending mine in today or tomorrow already set.
Sent from another Galaxy! Note the difference!

Nick you should save yourself the hassle and just call tmobile customer care. The lady right away told me to send then my phone and as soon as they got the tracking number they will send me a new one. I'm going with the white if I can.
Sent from another Galaxy! Note the difference!

I exchanged mine 2 times because they had dust under the screen . Too bad I didn't check the screen uniform last time.
Anyway I'm on my 3rd Note 4. I don't have yellow/blue/purple tilted part but the white is not uniform as I can tell the top half of my screen is a little bit dimmer. It's something that an average user wouldn't notice but I do because I'm extremely picky. Anyway my dad's note 3's screen has uniform white so maybe you can score a perfect amoled screen but then maybe you'd end up with another problem like dust or dead pixel.
Sometimes I hate myself for having such good eyes lol

My black Note 4 also has some issues with the screen uniformity. My right side has a pink hue as described above. I don't have the yellow tint on the left. Also under direct sunlight the screen creates a strange effect, it looks like the colors are inverted. If you place your hand to create a shadow over the screen then the colors look correct without the inversion, it is a very strange phenomena. I am trying to decide whether to exchange it for a white one or get another black one.
Are the white version somehow better in quality control?

Mine was looked like this. And everyone in the BestBuy from where I got this said this is NORMAL. Fortunately I could able to get a replacement from the other BestBuy. The new one is still not perfect (it looks similar to yours), but I can live with it since I don't want to send it for Samsung's Warranty service.
(My local BestBuy said they can exchange the smartphone for only one time. If I have a problem with the replacement, I have to send it back to the manufacturer for repair. I couldn't find this from policy in BestBuy website, but that's what they said to me.)

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...
