2nd transformer and now backlight issues

This is the second transformer I have purchased, received directly from amazon not even a reseller... This one the box has nasty finger smudges all over it and looks as if the box had been opened... but
Anyways... The issue being with this one is that (4) of the backlights are visable at all screen brightnesses. I did not have this issue on the other one I had (screen was flickering like short in the unit somewhere, so decided to return and order new one seeing as it would be faster then RMA)
Not sure if this is normal or if this is another reason to return this device as it seems like quality control seems to be an issue with this product.
Just seems annoying that is what I focus on all the time and not sure if this is normal or if I got yet another defective unit...
Please let me know if yours looks like this otherwise I believe I am returning this one and ordering another. This is unacceptable to me.

I just recieved another transformer from amazon today too. I sent the other one back and purchased this one. Both of the transformers have the same light bleeding like what you have. The one i just recieved today has a lil more light bleeding than the one i sent back. I'm keeping this one. Not going to send it back anymore.

That looks pretty bad. I have some backlight bleeding, but I have to go out of my way to see it (max out the brightness in a dark room).

Here is a picture of mine. And this is basically the worst possible combinations of maximum brightness, completely dark room, and solid black wallpaper.
The light bleed is only a little noticeable on the lower left side and maybe a bit in the upper right. But what is annoying me is if you look closely there is a small light color blotch in the middle lower area of the screen. Argh!
This is the second Transformer I had and the second one with some really odd screen defect.

already requested to ship back to amazon... this sucks!!! but when trying to watch a movie the bleed is horrible.
I wish my original one from walmart didn't have a short in the screen (as you moved it the screen would turn on and off) because that one was otherwise perfect 100% no screen bleeding even on 100% brightness!

I'd return that. That looks horrid. You pay for something and expect to be flawless. Now I mean if this was on display and someone tried to sell you it, you wouldn't have bought it if it came with that flaw now would you.

Yeah, I'm going to return mine. I bought it from a local Fry's Electronics and I got about 10 more days left to do the return. And they don't have anything in stock to exchange with.
I'm still struggling with if I want to exchange or get a refund and buy something else instead. Need a few more days to think it over (and maybe a look at a few more Galaxy Tab 10.1 reviews).

Nothing will be 100% problem free... just look at the ipad 2 screen issues... the transformer and its dock are a 1, 2 punch... and they said for any future transformer line the keyboard dock will fit, thats a +

I understand. But it seems like my odds of getting a defect free tablet may be higher with some manufactures than others.
My iPad was perfectly fine, first try. I've had two Xooms, both were perfect pieces of hardware (just too heavy and too expensive). My luck hasn't been as good with ASUS though.
Problem is both of the tablets I want seem to have manufacturing problems. I like the Galaxy Tab 10.1 too (though the lack of micro SD is why I bought the Transformer). But even Samsung seems to be having manufacturing problems with theirs too. Seems like far too many Google IO owners have their glass popping out of their bezel. Ugh. And it's looking like the production Wifi model has this issue too.

Well i deliberately wasnt lookig for issues and i can say the bleed is worse on the tf than my ipad 2. Also, of all sites, this forum craaaaaawls on it. Laggy as hell

XDA seems to really hate Android browsers. Haha. Opera Mini works MUCH better here though.

I thought I'd post a sample of the light bleed vs iPad 2. Both at 100% which frankly I'd never use this dark. However, the other shot is 50%.
I kept them small rather than two megs each. IMHO neither is acceptable at the price point. The tf changes with pressure the iPad 2 doesn't. The transformer is worse.
I have bad luck with screens. Also there are about ten stuck pixels seen on a black screen, I'm sure more if I run the color range.
Would you keep it? Don't think I will be. :/ and the iPad is getting exchanged.

O.K. mine issues:
Light bleeds on bottom right and right side of screen (on bottom left there is not such bleed as on picture this is kind of photo rendering issue)
http://img820.imageshack.us/img820/7805/32268220.jpg
Two defective spots of pixels on dark screen only
http://img851.imageshack.us/img851/3120/22912128.jpg
Zoomed defective pixels..
http://img812.imageshack.us/img812/7434/72512206.jpg
But I notice this in only %1 in my daily use, because I am not using it in dark room on dark screen at full brightness
What bothers me more is speaker disbalance (right is normal left is only 30% as loud as right). But if I have to wait for RMA I won`t take it to RMA because I just love it too much and don`t want to wait for stupid RMA.. Maybe I will give it to RMA after 23 months (in Lithuania there is 2 Year warranty)
BTW I contacted seller and waiting for answer and if they will not exchange it i will live with these issues
P.S. speaker test:

yah i noticed thatpressure on the back increasesthe bleeding but my photo was with no pressure. And dam this site lags on this transformer.
Still returning...sadly

just received my 3rd one in today. few dead pixels throughout the screen and then one big area that is washed out about the size of my thumb.
amazon refused to exchange this one and now says i have to go through asus. BULLSH**

i have to return mine due to the backlight as well, its got a bleed that seems like its getting worse every day.
also from amazon! i really dont want to send it back either

If you go to the bottom of the page on this site there is a arrow down box that says XDA 2010, switch it to XDA Classic and the website runs really smooth then.

thanks!

this is exactly how my current (3rd) is. the other two had bleed, but not as defined as this one's is. the others were more diffused.

Light blobs on black screen

Anyone else notice lighter blobs on their screen when a black app is loaded?
Try the night clock and tell me if you see any.
I use my phone as a clock at night and I just got this today and wow is it noticeable.

I also had that issue on my first unit, I had it replaced.
A quite bellow summarizes all the screen issues on the S2.
BarryH_GEG said:
There's really two separate issues that sometimes overlap:
1) The left side banding which appears along with a yellow tint either under certain conditions or, to some, in everyday use. This would seem to be a design issue as, to date, it shows up on every single phone produced.
2) Screen QC issues which include: 1) suction cup circles from production, 2) fingerprints on the inside of the display, 3) dead pixels, 4) vertical or horizontal lines, 5) ghosting, 6) white or black blotches, and 7) wide swings in color temperature.
There's no doubt the QC issues are probably vexing to Samsung. Based on the sheer quantity of displays they need to produce to satisfy demand they're either intentionally allowing displays to go out that shouldn't or are finding out from customers that bad displays got passed QC. Considering the large number of phones sold it's hard to guess the bad:good ratio but it would appear its larger than appropriate. And it doesn't appear to be getting better as newer builds seem to have the same issues as early builds. So banding may be forever but swapping phones may definitely help with the other issues.
I do think that adding the QC issues on top of the banding issue does compound it on some phones. That could certainly explain why some of us are happy and others aren't. There's still a lot of subjectivity at play so it will always be hard to say if what's acceptable to some is unacceptable to others. But with all the phones sold, you'd still think if more than a few percent had serious screen issues there would be a bigger audience for this thread and the issue(s) would have become more prominent on its own. I'd like to think things will get better but production demands may continue to allow QC issues to occur at higher than normal rates. Something that's frustrating for everyone - including Samsung.
Someone said something about the technology being flawed. Here's two links to stories where Apple was/is trying to get SAMOLED for their products. To me, it just helps reinforce that the benefits (color, contrast, viewing angles) still outweigh the downsides (screen life, burn in, inconsistency). And I'm sure Apple's engineers fully reviewed both the upside and downside before considering SAMOLED so it's still kind of a vote of confidence in the technology.

I'll have to get back there to have it replaced.

I've had it replaced 3 times now, I'm on my 4th unit. I can exchange one more time before I have to send it out for repairs.
I'll wait for them to get a new shipment in with different serial numbers (all the ones i've had start with the same 4 digits) and hope i get clean ones.
I called Samsung and the rep i spoke to told me that they have not heard of this issue.
Well they have 3 units in their back room with this issue so they will see it.
I think I will have to take a long-exposure photo to show them what the issue is.
Fingers crossed the next shipment is clear.

I've seen this isseu quite often when I had my phone exchanged mainly for a different screen defect, just be warned though since you had so many exchanges some people here might not actually believe that you went through 4 phones because 6Million phones sold and all that jazz.
Good idea that you decided to wait for another shipping, maybe you can even get a refund and just buy from another store that has good stocks?

I don't care what other believe or not. If they want to see my receipt plus the 2 exchange receipts I have here in this bag beside me I'll send them a picture.
Regardless, I must be one of the few people who have this screen problem AND use the phone as a night clock.
I am posting this for information to anyone who also has experienced or may wonder if their phone also has this issue.
If you dont have it, GREAT! I wish I had your phone.
(ps, this isnt a rant, just want this to be over)

I have zero issues with my screen; no ghosting, yellow/pink tint, light bolbs etc.
but no one believes me

Someone else in Canada (Toronto) went through five phones because of tinting issues with the display. He too exchanged them back-to-back from the same store. If you've been going to the same store, and there was a run of bad displays, all the phones built in sequence could be effected. Can't you go to a different store and exchange it there?

Have the same problem, its like blobs/smudges that are lighter black/greyish. Not an even black color.
Its best noticeable in a dark room without any other light, not even the light of the touch buttons or top bar active (so your eyes are adjusted to seeing in the dark). Using this image I can see it clearly. Auto adjust screen power doesn't influence it.

I think we all may have blobs to varying degrees. The other day I looked at my screen in bright sunlight with polarized sunglasses on. It made the screen look black but you could clearly see random beige blotches all over it. In normal use I think my screen is as close to perfect as there is and when looking at a black background in the dark I don't see blobs or blotches. The "O" in AMOLED stands for organic which means alive. Maybe what we're seeing is a by product of the technology.

You got it too!
Well, i'm glad I'm not alone sorry that you have it too.
Hopefully I will get a call from the store when the new shipment comes in and the issue will go away.
I tried going to another store and was told DOA's could not be exchanged at other stores that they had to go back to the store it was purchased at.
It is likely that all phones at Bell at all the stores at the same time may well come from the same batch.
I can wait over the weekend. I bought it on the 1st so still have most of my 30 day period to do the exchange. after that its repairs only. trying to avoid that.
I tried to get back the first one I had as it didn't have it as bad as all the subsequent ones I've had. Once a phone is marked DOA it can not be resold until it has been reconditioned and put back through the system. Understandable.

I agree and I can accept some imperfections but I'd like to get as close to "perfect" as I can seeing that I had it in the beginning (WHY didnt I keep the first one?!)
Oh well, I'll take what I get with the new shipment and be happy with it,unless there is functional issues, then I'll be

Well good you don't see any blobs or perhaps you are suffering from a certain degree of Nyctalopia. Sometimes a disorder is not bad, see no evil ... Nonetheless the O in AMOLED doesn't stand for alive, just for a chemical compound containing molecules with carbon.
I must add that two Galaxy S (i9000) models I have looked at don't have this issue, at all. The screens are fully and equally the same black tint/shade. Taking a picture to capture the problem has proven to be somewhat difficult, but this old camera probably isn't really anything to write home about these days.

OCD is also a recognized disorder in which the pursuit of perfection overtakes one's life. If I had problems with my phone I'd have no problem sharing them. I've posted tons of pics of my phone in the dark, in the light, on grey, showing apps, and at every brightness level between 0% and 100%. I'm not going to apologize because I have a decent screen. Though I do sympathize with those that aren't satisfied for whatever the reason.

I'm glad that all i have are these splotches on the screen in the darkness. it is not viewable at any other time and all other functions of the phone are perfect.
I can live with the splotches if i have to but would prefer to not. I'll exchange one more time and leave it.

I'm sure I'm not special. If you look at the low level of participation in the display threads either people have low standards or the majority of phones are like mine. Even within the display threads, 50% of the posts are by the same dozen or so people. In the other Canadian display thread a bunch of people from Toronto posted they had no problems. So keep spinning the wheel, you're bound to get lucky.

Obsessive–compulsive disorder is not how you describe it, perfectionism is. Some more of this perfectionism for a company like Samsung would not be bad at all.
It was not meant to be taken seriously anyway (hence the smiley). Albeit a joke, people whom suffer from night blindness will of course not see this particular issue though.
While I believe I did not post in the other display problem threads. I do have yellow tint and pink/blueish shade from all angles except from front. Which of course doesn't make it sound like a decent and proper SAMOLED+ display at all. Since I have a Galaxy S that doesn't exhibit these problems, it of course makes me a little disappointed.

I can not exchange my phone, probably because it was included for "free" with a Vodafone plan, even though I just have it a couple of days. The shop implied I could sent it in for repair but I am reluctant to do that for various reasons.

Not all phones are affected with the same assortment of issues but I find it hard to believe that your phone does not have any ghosting, its an limitation on the SAMOLED+, Im not saying your lying but I dont believe that claim either. For the yellow banding on the left side user to user and phone to phone subjective.

One of my thoughts also point to that a lot of S2 owners are first time users of SAMOLED screens, hence they dont know what to expect or have an entire low level of expectations. The S2 is my 3rd phone with a SAMOLED based technology and pretty much the expectation should be higher than the first generation SAMOLED right?
But all people say that these defects are expected are we are the minority as millions and millions of phones getting sold but theres no "internet media coverage" about it and they start bringing in other phones as a comparison when the only comparison needed is the previous generation SAMOLED.
I was initially very disappointed on this until I had my phone exchanged (Had to sort out over a dozen phones) and also XXKGx firmware alleviated the yellow banding, right now Im happy with what I got but I can be happier if the quality on the SAMOLED+ surpassed the first generation, The regular SAMOLED is superior in every way even if it was pentile. I just gotta hope for the best when the SGS3 and SAMOLED HD comes out.

This could also be a possible reason why Samsung has never said anything about the display issues on the S2, a lot of shops are refusing exchanges and sending customers to the service center and have repairs instead, probably Samsung has informed its retail channel that they will be replacing deadpixels only anything should be dealt with by the retailer.. well just a conspiracy theory =)

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

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

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

I've had tint issues with all three handsets. First two it didn't disappear after use. This third handset SEEMS to have gotten a little better after a week.
All three had light bleed. First one was least noticeable, last two including the current have two blobs of light bleed in the exact same places along the top of the LCD.
It's almost as if something during manufacturing (screw tightness?) has caused it on both handsets. They are both 212K and revision 11.
It's annoying me and I may do one final RMA once I see what this new wave of devices brings.

mine's fine.

I did what you asked, OP and I'm not seeing and unevenness, yellow tint, or brightness issues (aside from auto-brightness being stupidly low).
The only issue I have with my screen is poor colors. I have a One X and an iPhone 5 that I sometimes compare with my N4's screen and it's shockingly apparent that the N4's screen has colors that just aren't worthy of a top-tier device. The resolution is nice and all, but I like it when the colors are nice and accurate. It's most easy to tell when comparing images of people and looking at their skin. Now I'm no anthropologist, but I have a pretty solid grasp of what skin looks like. The One X is probably the best at representing things the way they look IRL, followed by the iPhone 5. I don't know if it's just my N4 or other people have the same issue. I've tried using apps to adjust the color (FauxClock with Faux's kernel, to be specific), but nothing makes it look quite as nice as my other phones.
I guess you never asked about the second part, but there it is.

I had that issue when I received my device, Used kernel setting to rectify the problem but after 4-5 days of use it gone away. Now device is perfect.
I recommend you to stay with it for 3-4 days before returning it and check.

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

I've had tint issues with all three handsets. First two it didn't disappear after use. This third handset SEEMS to have gotten a little better after a week.
All three had light bleed. First one was least noticeable, last two including the current have two blobs of light bleed in the exact same places along the top of the LCD.
It's almost as if something during manufacturing (screw tightness?) has caused it on both handsets. They are both 212K and revision 11.
It's annoying me and I may do one final RMA once I see what this new wave of devices brings.

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

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

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

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

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

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

My first nexus 4 (rev 10) has perfect whites except the bottom of the screen would turn yellow after warming. All of the 4 RMA devices I've recieved (rev 11) don't have this issue EXCEPT all the rev 11s are calibrated horribly leading to the entire screen being yellower than my rev 10 unit. The screens are uniform, however, I just wish they calibrated the phones like they did with the rev 10.
The new rev 11s have a calibration problem while my rev 10 has a glue problem.
The new rev 11s also have a dimmer screen than my rev 10. I kinda just want them to send a perfect rev 10 to me.

Interesting because calibration issues affect the whole screen. If any part of the screen isn't the same "tint" as another part and its noticeable then this isn't something that can be fixed with calibration. Calibration can only save a uniformly "yellow" or "blue" tinted screen. To that end I wish mine was uniformly yellow. Mine is a rev 11 and I'm on my second day with it and hoping the bottom and left yellow tint fades soon and that it's just glue. I've tried Fauxclock and applying various screen tweaks with a previous similar phone and it helped somewhat but there's nothing can be done about unevenness in the tint really unless its glue and it dries.

Users with defective screens (pink/uneven color temps), what model do you have?

I'm on my 4th phone, and this one is by far the worst. I busted out my Galaxy S4 to compare, and it's night and day difference. The S4 (also super amoled) is completely uniform color temp, and has almost zero color shift when you tilt the phone. Every 6P I've had has some type of pink to blue color gradient, and shifts to blue when I tilt it just a tiny bit forward (like everytime I'm reaching for the notification tray). I'm starting to think people with "zero issues" are either smoking the hype pipe, or having a completely different experience. All 4 of my phones are 64GB Graphite, with build dates of 10/25 or 10/27. It seemed there were a disproportionate number of 64GB Graphites reporting these issues. I'm thinking I keep getting phones from the same crappy batch(es). I'm wondering if there is any correlation between the color/size variants and these defects.
I'm considering returning the phone for good and either reordering in a month or two, or getting a 5x to hold me over until next years Nexus. I got Nexus Protect and the whole shebang with the 6P because I was planning on keeping it 2+ years.

2x bad 64gb graphites for me. 3rd one seems to be better, but not perfect. I'm not sure if I'll RMA it or not. Like you said it seems like every screen has issues and it's just a matter of how bad it is. The 3rd one isn't too bad at least.

Frost 128gb, no problem at all except for the random reboot.

Frost 64GB and same as you, no defects but I need to check if I got a random reboot while asleep as it asked me for the secure boot password when I unlocked it this morning. Strangely, once I did this, the phone appeared to have been exactly where I'd left it, instead of going through the usual boot up process of loading home screens, widgets etc.
I do wish to clarify that I do find this device to shift colors ever so slightly when not looking straight on. It is nothing major and I put it down to Google/Huawei not sourcing a good panel. It is the obvious shift expected from lower end panels due to changes in viewing angles. I do not classify that as a defect. I will post pictures of this in another thread in General.
At the most extreme near 180 angle, I can see some green rainbow effect. I don't know if this is due to my cheap screen protector or it has something to do with the Gorilla Glass treatment on the panel. It really is a non issue for me. I NEVER noticed ANY of this until I came along the forums and read people complaining about defects, making me go LOOK for them on mine. This doesn't mean others aren't suffering from defects.

Mine had the freeze and reboot issues. Did it 7 times in the span of 5 days. Put it on safe mode and still rebooted. Factory reset the device and clean install of apps and rebooted once. After that one random freeze, the device hasn't had one in 48 hrs and counting but still rma'd for a new device to make myself feel more at ease knowing that there is no internal hardware issues.

Not had any reboots at all but my 3 phones had increasingly worse displays. Alu 64gb, manufacturrd 18/10, 28/10,28/10. The original 18/10 was the best of them all but still not good with pink hue on the left side of the screen.

I also have the color shifting, but this is probably caused by the tempered glass screen protector. anyway, I always look a the device with an angle of 90 degree.

Thanks mods for cleaning up the hate speech. It amazes me people think we should be grateful and accept any crap Google ships. The way QA works, it's not an issue unless the customers make it an issue. If Google can save money and use grade B panels, and their customers don't seem to mind, then next year they might use grade C panels.
This is what my 6P looks like on the google homepage at normal brightness levels: https://goo.gl/photos/z77YPDta247Jh3Zt5
Last I checked, there is no gradient on the google homepage that goes from pink to green. And if you're curious, here is what that looks like next to a Nexus 5X: https://goo.gl/photos/3huN7dPbeBKqrodf7
Every one of my 6Ps has a color gradient when looking directly at the screen. That's not taking into account the crazy rainbow effect when you tilt the display just a few degrees any direction. I had multiple Galaxy S4s, which also have a samsung amoled screen, and they are all completely uniform and have close to zero color shift at normal viewing angles.
So to everyone that thinks we are just picky @#[email protected], in all my years and hundreds of consumer electronic devices I've owned, I've only ever RMAed two other devices: a plasma TV that buzzed like a bumblebee, and an og PSP that had dead pixels and completely outrageous back light bleed.

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...
