oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.

I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.

This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy

My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

ok thanks, it's just reassuring to know that its not only my n1 experiencing this

Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

Hmmm!!?? purple-ish screen tint on lowest brightness on my new NS

Well I used to cause a big fit about the N1's HTC would warranty swap me because of this issue. The first N1 I purchased didnt have this problem. I just bought the NS today and right away I noticed the same exact issue. Is it safe to say that maybe this should be considered a normality rather than a defect?

Its actually the Amoled tech itself...It cant reproduce whites perfectly so they come out cool....thats why its off a bit but in return you get exact blacks
Lcd's are opposite...you get real whites but no real blacks.

It shows up in certain shades of grey, like in contacts and in clock dimmed while set on lowest brightness setting. The whites and other colors display fine.

Yeah i saw that too but thats the OS thats doing that so you should be cool

Is it either on the bottom or top? I have watched a YouTube unboxing video clip says that when you browse with your nexus s to the top of the page, or the the lowest of the page, it will actually dimmed darker. This is to let you know you have reached the lowest or highest of the page. You couldn't scroll anymore .
Sent from my Nexus One using XDA App

No, it has nothing to do with scrolling. It's exactly what I've said. Also I'm pretty positive its not a software issue. It's definitely the display. It must be either new materials Samsung is using for there displays or a calibration issue!

I also noticed this today, the purplish tint while on lowest screen brightness in a very dark room. If you bump up the brightness slightly, it goes away.

Nothin for me. No tint.

For me when I have the screen off I notice there is a purple tint to it compared to say a vibrant maybe that is the cause of you're problem

what i'm speaking of shows only while the screen is on.

This is right on the money. Same exact issue with my N1 and now i see it with the NS. I notice this on the N1's because my very 1st purchased unit displayed perfectly without any kind of discoloration after dimming the brighness below 50%. Soon after I warranty exchanged that unit for another, I recieved one with the tint issue. After I exchanged a couple more times, I recieved another without the tint issue but the touchscreen problem was much worse than the others i've had so i sent that one in. After that, i havent received one without the tint problem yet. I bought the NS expecting not to see this problem again and lo and behold, it surfaced as soon as i dimmed below 50%.

I checked out the demo phones, and every one had it on the lowest brightness setting. I think it has something to do with the new colors in the OS. If everything was black, it would be harder to see, so they use a little purple to differentiate when on a low brightness setting. You dont have to turn the brightness up much to make it go away

The issue I'm speaking about, it doesn't literally "go away" in the manner you might be thinking. Its just that certain shades of greys are affected by it. Here's how to test for it, goto a dimmly lighted area and set the brightness thru the power widget to highest. Next, goto the dialpad on your NS, and notice the bar topright below the menu tabs, it should be grey. Now go back to your power widget and switch brightness to lowest setting. Go back to the dialpad and look at that bar again. It still should remain grey no matter how I adjust the brightness levels, but instead it'll shift to a light purplish hue.

It's because of the amoled screen uses the pentile sub pixel layout. I thought this was well known. All Samsung amoled screens do this as the all use pentile sub pixel layout, which many people hate as the feel its not as good as the true 3 sub pixel layout screens. And It's true it is not as good, but I still prefer it over non amoled screens, crap pentile and all.

Yes I know about the subixel stuff with the amoled displays, but I have to disagree with you as far as all of them display this way. As I've mentioned before, I've had 2 N1's without this issue. I'm gonna go back to BB to see if they can open a couple so that I can do some comparisons.

As I said, mine is this way too, but went to 2 BB's tonight and checked out the demo models at each store. They both had the weird purple tint as well, on those few shades of gray, like you pointed out. I also watched the Engadget video review and could see the purples on their phone too. I think all the NS's are like this, just the way the screen is. Perhaps in a software update, they could tweak the colors a bit and fix it.

actually
this is not true. i had to go around 4 Galaxy S screens and finally i was able to find one without pinkish color in it in low brightness.
if you want to tell if you have pinkish hue. download a solid dark gray wallpaper. turn the brightness to low. if you see it pink. then you have defective screen. i repeat. its a defective screen. dont justify your self with it.
i went through 4 galaxy S and i was able to find one where white is actually white and closer the the cool blue. not a friggin pink
and its not amoled screen either. the iphone 4 is same issue. go to macrumors forum and check for your self.
i went through like 6 iphones to get one with cool blue and no yellow tint in it.
the difference is light and day now when i compare my iphone 4 to my other friends.
if you have an OCD with this " because i do. i have OCD for light leakage, same black level the whole screen, yellow/pink tint on the screen in low settings "
the whole phone to me is nothing but a big screen. if they f*** that up. then its useless

its not a software problem.
its hardware issue. when my phone with pinkish tint along with my brother one didnt have one, i thought it could be a software issue, and we even both implimented the voodoo fix : galaxy S : and still looked different.
its a hardware issue. and i really think you need to change your phone. because if you are like me, who cares alot about his phone, then once you see someone with a nexus S and you compare the whites and the gray colors on both phones. you will be one sad panda.
hell put the brightness up to the max even. you will still see the difference in white level between a pinkish/yellow tint screen and cool blue one. its not even funny :/

Yes I'm definitely OCD'd on this issue lol. I'm still not total convinced that this a defect yet. Ill be going to a few BB's today to do some comparisons. If I do find one without the tint, then cot dammit, shame on Samsung for allowing this to slip thru on these screens again! Ill report my findings later.

My NS suffers from this horribly on top of the bad touchscreen issues it also has. Def. a defective unit

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.

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.

GT 7.7 AMOLED producing similar issues as the SGS2 and SGN

Here we go again, looks like Samsung hasn't really fixed any of the 'issues' with the AMOLED display.
I can clearly see the bottom half of my 7.7 has a heavy yellow tint compared to the top half which is whiteish.
Anyone else noticing the same?

My screen has no issues whatsoever, so far as I can tell. I just checked on a grey background to see if I could detect the yellow tint, and nope, it was clean and uniformly grey for me.

This being my first amoled display - I was blissfully unaware of "limitations" of this new technology. So I had mine on full brightness ( 70 -90%) for the first week I would say
Then I read some other posts like ths - then realised this was not a good thing to be doing. Its like plasma technology (although much better than lcd/led in terms of picture quality) it still suffers with the "image burn in" with static content. It took about 9 generations of plasmas to "cope" with this issue.
SO i would not recommend high brightness for the first week to two weeks to allow the screen to "bed-in" but I am not sure of how oleds function or they even need this.
I do have a very faint yellow hue that matches exactly with the system bar at the bottom. But off course the system bar is static and hides this all together. The problem is when you change oreintations - mine is 99% in landscape so not noticeable for my use.
However in portrait, this again is only really visible on a minimum brightness setting and against dull grey background. If I put up the brightness up to 25% it is really difficult to make out & any brighter I cant see it.
If it bothers you enough then to minimise static content:
1) Screen timeout from 1 - 15 minutes
2) I also now use "hidebar.apk" to hide the system bar. Can be a bit buggy but works on the whole and is free. Use it mainly when browsing for a long periods of time.
3) in the default browser you can change to full screen mode, in settings go to Labs -> select quick controls. This gets rid of the bar at the top.
Finally, full screen web browsing !! Also the quick controls are slick, once you get the hang of it. Just press on the extreme edges of the screen to bring it up.
Or just get a replacement. In your case it sounds bad enough.
For me I cant notice any issue 99% of the time. Even If I knew about the issue beforehand, I think the screen is just way better than anything out there for at least a year or two. You cant fault the rest of the tab - its pretty mint

just so people are aware, this screens "issues" are only for the neat pickers, they are not visible under normal usage condition when the screen is set to auto or manual
the only way to see those is when you set the brightness all the way to Zero
as long as you keep brightness at 20% or more you wont see any of that

Is this the same issue with the Galaxy S1?
On the bottom half I have an area that is yellowish on white pages. And when you look at a black image in a dark room the black on that area is more dark.
When you turn the display off and look against the sun or similar bright light source at a shallow angle you can see that the golden mesh is not flat in this area. it is bumpy

My screen has no issues whatsoever, so far as I can tell. I just checked on a grey background to see if I could detect the yellow tint, and nope, it was clean and uniformly grey for me.

Here we go again, looks like Samsung hasn't really fixed any of the 'issues' with the AMOLED display.
I can clearly see the bottom half of my 7.7 has a heavy yellow tint compared to the top half which is whiteish.
Anyone else noticing the same?

Pictures would be nice so we can take a peak, Im not sure how well it would translate but it should visible enough.

For me there is a huge difference between not having any of those screen issues and saying 'its only visible when X is done'. I prefer to have a flawless screen If I decide to purchase, the money back guarantee / refunds are there for a reason.
I use autobrightness as well and it does drop to 0% when Im using my device in the bed room with the lights off. of course I dont have a Tab 7.7 yet but this is how its been since my Galaxy S days and I've never had to do certain things to prevent flaws from surfacing, it was just flawless to begin with aside from the Pentile limitations on the text.
Then again your opinion, my opinion. I hope to see a flawless screen on the Tab 7.7 though but Im not expecting much.
But we shall see once its locally available.

Dude, the 7.0+ is probably better option for you. Save some money and headache because the technology is samoled+ not ++ or whatever the next generation is going to be called in 12 months.
I would say "normal" usage patterns and many will have flawless screens. Blast it at 100% brightness with a static image for a week - you will not be a happy bunny

Many will have flawless screens but you advise against it
I'll just have to wait for one that is flawless and purchase it, putting the stock keyboard in landscape mode easily shows this issue. For what its worth this yellow tint no matter how slight will show up in HD movies
Even with my phones Im more of an indoors user so my brightness stays either auto or probably fixed at 20% and I usally drop to 0% when web browsing in bed.
But I'll have to see it in person.. or its another refund process.
EDIT:
Believe it or not some review reviews on the Galaxy S2 and Galaxy Note in HD format actually shows a noticeable hint of yellow tinting.. I've seen 2 HD reviews/previews so far and it looks good. Hopefully it translates well in real life.

dont get me wrong. all i am saying that for me i have to go through the following to see something.
1) reduce brightness to 0%.
2) use third party app to dim screen below normal brightness threshold.
3) use third party app to remove system bar
4) change background to a dull grey
so it all depends on ur definition of flawless.
as i say under normal circumstances it is a non issue.

For me its just a 3 step process
1.) set the brightness to 0%
2.) pop out the stock keyboard which is already grey
3.) check for color uniformity
Heres an example on my Galaxy Note: I've cropped the pictures and its a little misaligned be the judge if Im nitpicking or not.
My 'normal' conditions involve using the tab at 0% brightness in about 85% of the time. But I'll have to see it in person to judge but going with that you said then maybe the RGB stripe handles discolorations a bit better.

What am I supposed to see?
I can see that the left part looks "normal" and the right half has yellowish gray colors.

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...
