[Q] Anyone else have parts of their screen with red tint? - Nexus 6 Q&A, Help & Troubleshooting

Here's an image of my first Nexus 6 (top) and the RMA replacement (bottom): http://i.imgur.com/wNbgFo1.jpg
As you can see, my first N6 had a pink tint across the whole screen which is why I initiated the RMA. While the replacement is better, there's still a red tint to the right half (bottom half in portrait). Actually looking at both, the reddest tints are in the right half.
I also have some bands that are dimmer than the rest of the screen which is very noticabke when scrolling but not so much if looking at a static picture.
It seems these really are using Note 3 Samsung AMOLED panels because the same complaints were posted on another thread last year.
Both devices were manufactured 11/12 if that makes any difference.
I'm just wondering how common of an issue this is. I don't think I'll RMA again for awhile as I'm just taking up devices that should be going towards fulfilling orders and my replacement is serviceable. But considering the price, I really expected better and I don't think I can stomach the flaw.

You answered your question (the very end statement). I can't really see what you're trying to show in the picture as everyone see's colors differently and not all phone displays/pc monitors are color calibrated in the same ways. GL finding the right display for your tastes. They all have compromises albeit some less than others

You don't have to have a calibrated screen to tell that the top screen is darker than the bottom screen. It's also not hard to tell that the left is lit brighter than the right on both. Whether you see pink or not may be arbitrary but that's why I put it in the description.
My original question of if anyone else is having that issue is not answered just because I found a thread on a year old phone that may or may not be using the same panel Would prefer if other owners chimed in so I don't waste my time RMAing if it's unavoidable.
But thanks for the reply.

I have the same problem, the upper part of the screen has a pink Tint and it's bugging the hell out of me, but since i've had my friend bring it with him while coming back from USA, i'm obligated to swallow up whatever defects i find in it

My mistake. In your picture it looks like the right side of both screens is a little darker than the left.
That said, and you don't have to answer these I'm just thinking out loud here, what were your camera settings when you took the picture? What camera did you use? What screen brightness was each display set to? Could the ambient lighting in the room have affected the photo results? Could there have been inconsistencies in the results caused by the angle of the photograph taken? Those are a few of the variables that I can think of that could skew what we're all looking at.

I used a Sony NEX-5R Mirrorless DSLR. I probably didn't use the best settings (automatic with manual focus) but I was kind of in a rush to get the old one out to UPS to get the CC hold for the new one to drop off. I didn't use any special lighting, just natural day time lighting. I think the pics are pretty representative of how tinted they were though because the old one was very red heavy everywhere. I should have taken additional pictures of the home screen to compare. On the default background, the new one looks turquoisish but the old one was dark blue.
Brightness was at 50% for both and I believe I had adaptive brightness turned off. Either way it was light up much brighter than I keep it at day to day (I usually have it at 25% at most with adaptive brightness on). If I had to compare the pictures to the actual devices I'd say the camera didn't pick up enough of the red tint. So in person, it's much more red and much more obvious.
But honestly, I don't care that much about the tint as much as I do the uniformity. I can live with an all yellow tint or an all red tint if it was consistent across the whole screen. I'm sure a custom kernel will come out at some point with gamma calibration so I can adjust as I please. But the way it is, the top half of the display looks brighter than the bottom half. The easiest way to see this is by setting the keyboard to Material Dark and putting the phone in landscape. The left side of the kb will look greenish grey and the right looks darker purpleish grey.
I've not heard anything about this issue. Maybe one or 2 posts on here and reddit regarding banding. Everyone else says their screens are perfect. I was hoping people would share their pictures so I can tell if I got 2 bad screens or if they're all like that and most people just don't care.

I hear ya. The uniformity, or non, would bother me too

Welcome to the world of amoled. .lol The note 4 has same issue.Replaced 3 times still have pink/purple hue..If u test this image out with brightness turned down a bit you'll see darker area's on display that's causing the issue.

I can see the light / dark difference in the screen with that image, but it doesn't bother me across such a dark background because it still looks grey all over (just to different degrees). I actually find that it's much worse with light backgrounds because it doesn't look all white or light grey. The darker parts are always pinkish. It also doesn't help that Lollipop is all about white screens everywhere either
Also found out that I don't qualify for the extended holiday return, so I have until Friday to return it for a refund. I guess I'll be calling for device #3 earlier than expected and crossing my fingers.

My note 4 looks similar to ur replacement device, the first 2 were really bad,half of bottom was really pink,2nd one the top half was really pink..This one I'm learning to deal with,it just blew my mind last night while laying down in dark messing with wallpapers and noticed all the uneven darkness on dark grey image,dark area's and faint vertical lines everywere.It appears it's from uneven distribution of glue.

I dislike the warm color on mines. Nothing is perfect, there's always something to disliked

Just wanted to toss in my 2 cents. I have had two Nexus 6 devices now, both with discoloration. Both are from ATT. The first device was darker to lighter, from left to right. Current device is darker on top, and lighter on the bottom. It is really frustrating because I love the size, and the screen is great in terms of resolution.
I am thinking about taking this one back as well and returning it. I have never had problems on my smaller devices. It bugs the crap out of me that I can tell the difference, mainly on lighter backgrounds. I don't think I can live with this phone for a year. Waiting on the M8 GPE to get lollipop might be a better solution for me.

Do you recall what the build date for both phones were? Not sure if it matters but couldn't hurt to collect that info.
I just called for RMA #2. Hoping it's at least not worse than the one I have now. I think I'm in agreement with you regarding just returning it and waiting until next year, but I already gave the Nexus 5 to my wife so I'd be downgrading the Nexus 4 she had before that...ouch.

Assuming the date under the sequence number on the box is manufacture date, this one looks like 11/17/14. I didn't think to check out the original device build date, but it shipped 11/18/14 from ATT online and I received it 11/20/14.
I have had my current one now for a day, Moto and ATT claim devices shipping currently shouldn't have screen issues, although my issue is different than the screen not turning on, or flickering.
I was so ready for a big phone, I am still within my 14 day return period, and I'm wondering if I should try this again to see if I can get a good one.

Hi All,
I'm coming in late but I just got my Nexus 6 from AT&T last night. I've been using an N5 since may and haven't had any issues. I noticed this morning when opening Hangouts, Chrome or any other page that displays white as the background that on the top it has a more greenish hue and towards the bottom right it has a purplish hue. I thought it was my eyes at first because it's subtle but when I'm paying 700.00 for a device it better have a perfect screen. So I played around with the adaptive brightness, rotated it etc. It didn't look any less green to purplish. The bottom right side of the phone in portrait (to the right or the charging port in portrait at any given appropriate angle) had a more purplish hue than the top left (opposing the camera). I'll probably be going back to at&t tonight .. which sucks because I JUST got it set up how I liked it. I hate rooting anymore which is why I buy GPE devices. I could have gone with any other device and rooted and may have to get back into that game if this is how crappy this display is going to be. Also I might add that the encryption does slow the device down a little bit compared to the N5.
P.S. Ignore my sig, I need to update that..

For mine (bought from tmo) the bottom is slightly darker than the top. I only noticed when looking hard for the "link" issue. Out of all the issues I could have had, I find this the least annoying of them.
Over all I'm happy.

I just got my Nexus 6 direct from Google (one of the lucky ones) and for the first time ever, a phone screen is really bugging me. There is a tint, darker from left to right. The most expensive Nexus I've ever bought (and I've bought them all) and the worst display. Very sad.
Here's some images, one with contrast as it was hard to photograph. Much more noticeable to the naked eye.
Does anyone NOT have this issue? If so I'd rather take the chance on replacing it.
Update: Returning it for a replacement. Google kindly gave me $10 credit for the troubles.

I received my replacement. The screen seems perfect. No gradient. There are definitely some defunct ones out there, beware. Mine is going back now. I hope you don't get it.

Pink screen

Wow! The pink screen sure is annoying!
I just got my replacement phone from HTC (at&t N1) for my reception / audio issues.
The new screen looks horribly pink - noticeably so.
I think its just luck of the draw with these screens. My first phone had a slight green tint, but was pretty close to natural colors; the replacement is very red'ish tinted. My original phone had an issue with the cpu throttling not working properly any more. the replacement screen causes the grey areas to appear pink/purple'ish. (even the black areas)

This is really bad - I will probably ask for another replacement, especially since the new phone has really bad reconnection issues. QC on the nexus one is just beyond bad! This should NOT happen.
I wonder what percentage of people have this tint problem...
[POLL] do you have the red tinted screen?
If you do not know what I am talking abut, or never noticed it; turn your screen brightness down to its lowest setting and then open up the stock android keyboard. (it becomes most pronounced at brightness settings below 50%) If you have the problem, then the keys an surrounding dark grey will have a red tint to it. The red tint is only an issue for the various shades of grey; black and other colors are not affected. (on my screen anyway, and white may be a bit off as well)
The reason I ask, is that I recently had an issue with my CPU getting stuck at 100% load at random, so I sent in for a replacement. I got the new phone in the mail, and it appears to be a new, or at least a failed/repaired assembly line unit. (received a -04 part number btw)
This thing has a bad red tint to the screen, worse than my GFs nexus which we also received a replacement for. (both replacements had worse red screen) I might could get used to it, but currently it is distracting to no end.
Problem is, is that my original device has seemed to stop getting the random 100% CPU load problem. I wiped and flashed back to shipped ROM and then re-did the update path through to 2.2 build. (completely stock no root or unlocked bootloader) I did have an issue with the CPU getting stuck at 100% after that, until I uninstalled an app and reinstalled it; seems that when switching from this app to another app would cause it to get stuck. So now I am on the fence about wether to keep the new device or the old one; the CPU issue may actually be a hardware issue and come back at random sometime, or it may not.
edit: BTW is there a way to edit the poll? Iy seems that some have the tint issue at first and then it gets better. I would like to add that option.
edit 2: Pictures of the new and old devices. If you can also see my trackball is also sunk in too deep.
New on left, old on right.
No red tint on mine.
none on mine either
The first couple weeks with my nexus it had a purple tint at the lowest brightness. This is now gone.

So it got better? This could explain why the GFs screen has much less red tint than the new devices. Just sucks that my original phone is near perfect in the color area.
As far as it being purple tint, the darker colors tinted with red would appear purple-ish. The only colors I have noticed being "off" was grays and brown. (when displaying full screen single colors)
easiest test is to go to htc's website, ash/grey deigns of the site are in pinkish tint. Which is the case for me and as well as my friends, he is on Tmobile, I'm on At&T. I think this is a problem in the newer batchs of nexus. I bought mine this April.
In any case, it doesnt bother me, not a deal breaker considering I have Flash 10.1 on my phone
I would say majority of the recent owners from last 4-6months.

I bought my nexus at the tail end on January. (around the 25th) I bought the GFs nexus a few days later. (she has the tint issue)
And I added pics in one of my prior posts.
Really would like to edit this poll; add about the self fixing and about when you bought/received your device.
This poll will determine if I bother with having a third replacement sent out. I'm also running a solid red screen at full brightness for about an hour, see if that helps take out some of the red's over saturation. It affects yellows as well, I just noticed.
I ordered my Nexus when it was released and also had a purplish tint when brightness was down. I think androidandme did an article about it... maybe. Anyway it didn't bother me because I always leave it on full brightness anyway. Just checked it out on low brightness for the first time since I got it and I can confirm that the tint went away.
There is a stickied thread in the Desire forum about screens with a pink tint, might be worth reading if you have it. No idea what's in it though

I agree it is something to do with the type of display, but it seems that many do not have this issue; my first device did not. If I had always had the issue, I would not be noticing it now, but the difference is jarring.
I'm tempted to be careful with the "void" stickers and swapping the displays out myself.
Leaving the solid color running helped a small bit, but not enough to really matter.

I don't notice the tint as much unless I have the two phones side by side; though I still see it. As you can see by the pics I posted on the first page of this thread, the difference is huge.

[Q] NC LCD Whiteness/Brightness Differences?

Hi All,
Newb to XDA forums tough I have been following quite a few of the development threads for weeks now (OC Kernel, Phiredrop ROM, Tablet Tweaks, etc...). First I must say I'm super impressed at all the development being done for the Nook Color, us NC owners are definitely blessed to have an active XDA community full of brilliant developers!
But here's my first question about the Nook Color, has anyone noticed that some Nook units have a whiter/brighter screen than others?
Long story short is I've gone through about 5 NC units bc of various problems and have noticed that two of the five units I've been sent so far have noticeably whiter and brighter screens than the other three. This is with the brightness setting set at the same level on each Nook. It might be a color temperature or RGB setting difference between them, but I have no clue how or why they would be different since they were all factory fresh units. Does anyone know if Barnes at some point changed color settings (within kernel?) or started using different IPS LCD parts during manufacturing at some point? I did notice that the two I had with whiter/brighter looking screens had serial numbers that started with 20111, while the others had SNs that started with 2010 or 20110. Maybe they made some settings or parts changes during the newer production runs?
I know a lot of you might be thinking I'm not judging them under the same lighting or that the brightness settings are set to different levels, but I assure you that I am placing them all next to each other and always set them to the same brightness level for comparison. Admittedly, I am a bit particular about how the quality and appearance of my LCD screens, but even my girlfriend who is not a big tech person can easily tell the difference between the screen by looking at them from a few feet away. She instantly picks out the one that has whiter whites and appears "brighter" (again with brightness set at the same level).
Of course if you don't have two of these units next to each other for comparison it might be hard to see the difference relative to one another, but I can assure you the screen whiteness differences are there between some units. Wondering if there is any way for us to control these settings via kernel changes or some other changes (color temp, hue, RGB)? My problem is that I currently have a perfect unit that has the dimmer screen, and a brighter unit that has a dead pixel and am trying to decide which I should keep and which I should return. I actually prefer the colors and appearance of the one with the whiter screen but get distracted knowing there is a dead pixel. So it's a tradeoff. However, if i know I can change the colors of the screen and make the good unit look whiter/brighter down the line, I will definitely keep that one.
Any thoughts/advice would be much appreciated.
Thanks!
anyway u can post a high def video of this? would help on what your seeing. my nookn color is def a lot yellower than my other devices. but never saw a nook that's whiter than the other
I can try to take a video tonight, but not entirely sure if the color/brightness differences will be captured on the video but i'll give it a shot.
I tried not to use the term "yellow" in my initial post since whiteness level is relative, but that's basically how my gf described it - "That one looks yellower than that other."
yeah, i find whites on my nook very "yellowish" compared to my phone.
too bad there's no settings to change the color temperature on the nook.
Actually, that was one of my questions. Is there any way to change the color temperature of the Nook LCD screen or something along that line via the kernel? I have no clue about kernel parameters, but was hoping someone like Dalingrin, the resident kernel guru, might be able to answer this question? I think I've seen some ppl create apps to update color settings in the kernal for android phones.
I have an NC with serial number started 2004, which has very beautiful screen, but just three dead pixels. so I called B&N to have a replacement, and yesterday, the new one arrived (serial number 20112..). When I have both devices sitting next to each other, I can instantly tell the new one is VERY VERY yellowish (or say, the color is way too warm).
I have to call B&N to have another replacement, and the representative told me the yellowish is a known issue, though happen rarely. My personal experience can tell that even the newer devices may still have the yellowish problem.
There goes my theory about newer serial numbers. Have no clue why some units are yellowish and some a nice white then. But so far out of all the units i've got the ones that had whiter screens all seemed to either have dead pixels or some dirt or other particles stuck underneath the glass, and the ones with the yellowish screen seem to have no other screen defects. Probably luck of the draw, but I've got some pretty bad luck so far then. Love the NC, but I'm thinking the quality assurance is pretty shabby at this point.

Sorry if this is OT, but this is the part of your post that most caught my attention. What the hell are you doing to those poor Nooks? ;-)
But seriously--what the hell?
Lol... as mentioned, two had dead pixels one of them the pixel were dead center, one had dirt under the glass, another had a loose back and a yellowish screen. Now trying to decide which of the two I have left to keep. The one with one dead pixel on the right side but a white screen, and the other that has a yellowish screen but no other issues at all.
I hear u with the yellow tint. had this next to my bros Ipad 2. and the nook was embarrasingly yellow. and my apple fan boi bro said it looks like a macaroni n cheese screen.
Our first had a definite "yellow" tint to it. VERY hard to notice, but I seem to notice every imperfection. Exchanged it and the second looked better. A friend of mine bought one and it had the same yellowish tint. Doesn't bother him though. Says he doesn't see it.
Are you running the stock rom/kernel? I know on CM7 there's definitely a more yellowish tone to the screen than on Nookie Froyo or the stock rom.

Didn't realize there was such inconsistencies with the NCs regarding color temp until I read this thread. Without being able to compare screens I have no problems with mine as it seems pretty good to me, serial 2010xx dated Feb 2011.
I guess I was lucky that the one I bought had a good screen without a single dead pixel. That was the only thing I checked as it was the most important thing to me. Couldn't care less about any other cosmetic issues. Build quality was better than I expected for something of this price, but recently the left side of the bezel has started to creak annoyingly when I hold it.
Definitely can't compare to those tablets twice it's price. But AFAIC, it works very well and with the phenomenal dev support, a Nook running CM7/OC can't be beat.
If I were you, I'd return the one with dead pixel. Built into CM7 there is "Render effect". Besides the night modes, there are some basic calibaration profiles in there. Maybe one of them might make your screen a bit "whiter".
edit: I just checked and it seems all the N1 profiles made my screen seem warmer. I suppose a few more profiles can be implemented, perhaps you should start a petition to the devs?

Nexus4: Bright Pixels

Hey guys,
I already mentioned this in the German thread, however it may concern a couple of more people.
I just received my replacement. The reason I ordered one was I got 2-3 tiny little bright spots close to the top right corner on the display. Exactly they are located on the opposite side of the back camera. These pixels are brighter than all others. Though the spots are very tiny you can notice them e.g. if I look closely at the Google search bar on your home screen. It's not that they are disturbing me but I feel on a new device there should not be such issues. You never know how far this is going to get.
So, the today's device is made in Jan 2013 and it has the same spots. I want to ask if anyone of you has the same issue. Just download a pixel test app ( e.g. Dead Pixel Test by Ossibus Software) and look at that area at different angles and colors. I attached a picture to get a better feeling of what I mean.

Sometimes it is better not to go looking for these tiny flaws as often we find them.
LCD panels do have flaws, and a certain number will leave the factory with some broken pixels, some good information here http://en.wikipedia.org/wiki/Defective_pixel
Some applications claim to fix these pixels by flashing the screen with lots of colours, and they seem to work for some people, typically however the pixels are intermittently broken and would have probably just started working anyway!
Manufacturers of LCD panels let a certain amount of screens through with broken pixels simply because otherwise they would be throwing too many away and so their cost would be considerably higher.
I'm not sure if yours are broken pixels however. How are you seeing these? If you are cranking the brightness up to full and viewing a dark colour you can often see tiny pin holes of light, and this is just tiny flaws in the filters which are so thinly applied tiny breaks happen, which you wouldn't see in typical use. You'll never find a screen 100% perfect if it is this you are seeing.
What do you see if you have a dark black background and the phone on normal brightness? Pixels stuck in the "on" position would be very clearly visible. On a white background stuck "off" pixels would be clearly visible, either by showing a tiny black dot, or typically a dot of a different colour.
If you can't notice them in typical use, just don't go looking for them :good:
If they are stuck pixels you have been unlucky, and the only option is another RMA.

Had a "hot pixel" almost in the same place as yours when I got the phone is December. RMAed it and the replacement is looking good now.

Hi
Sometimes it is better not to go looking for these tiny flaws as often we find them.

This is good advice. My last 4 phones (captivate, atrix, gnex and N4) all had some kind of defect with the screen. Captivate had slight burn in, atrix and gnex had black spots that can be seen with brightness on lowest in dark room and my N4 has minor screen bleed under the camera.
Its not hard to find problems with LCDs if you look close enough but none of the defects i had could be seen with normal usage so i didnt bother to return them. There is a chance that you will get a replacement with worst defects not to mention all the hassle of having to do a rma. But then again this is xda where people freak out when they see a scratch on the screen.

Thanks, mate.
When it's black I only see light bleeding from the top. Therefore, they are not dead. I believe, during the manufacturing process a layer behind the the pixel gets damaged. I filed for another replacement. However, I don't think it'll get better.

[Q] Uneven Red tint on the screen?

Anyone having issues with their screens?
I have a red tint near the top right corner.. the bottom left is more bright than the top... it appears like a gradient accross the screen... noticable on dark greys... What should I do? is it a defect or are all devices like this?
Help please. any inputs will be appreciated.
How low is your brightness and is it set to adaptive?

The brightness is set to full, adaptive is off. When set to full, the tint is low but noticable.. when set to 50% the tint becomes more prominent.. and I do not have a problem with the tint.. it is just that it is not uniform.. the top right is tinted while the rest of the display is not.. it is really disturbing when reading an email or typing in landscape.
I think color uniformity issues are quite common on this device. You see some threads on reddit and also here on xda about this issue, most people have some sort of yellow or red tint on parts of their displays. The display of my Nexus 6 is a bit more yellow to the lower right of the screen, however I really only notice it on higher brightness with darker colors in apps like Google Camera or the Material Dark keyboard theme. It used to bug me in the beginning, but I somehow got used to it. I don't see the need for an RMA and get a potentially worse device with other defects as mine is perfect otherwise.

I was thinking the same.. it doesnt bug me that much. but when it comes to keyboard on landscape and specially the google camera dark grey background.. i can clearly see it... otherwise my device is perfect. I read a lot of articles too.. the device is expensive and at such a price getting a flawed display is unacceptable. My main question is are all amoleds like this.. because I had a galaxy s3 and it had a perfect display with no tint. Are all nexus 6's suffering from this problem or is it just a defective batch that is affecting some people. ? My device is just 2-3 day old so I can get a replacement.... although I am hesitant to do so..

I know the feeling, when my device was just a few days old I freaked out like this too. It's hard to justify at this price point but the truth is, no device is perfect. I went through several N5's back in the day and none of them were perfect, most of them had a few dead pixels, creaking body or even dust particles in the camera.
If you say your device is perfect otherwise, won't you rather live with such a small and hard to notice defect than going through a cycle of potentially worse devices? If you ask me, don't go for a replacement. But in the end it's up to you.
Getting a replacement.

Here my vendor is sending me a new device. A box packed one. It should arrive in 2-3 days. The tint on mine isn't noticable when the brightness is above 70% , but I cant use the phone continously at night at such high brightness. Besides the tint is so bugging me when reading anything.. browser, play books.. the uneven color temperature from top to bottom.. it is really annoying and considering that I have paid so much for this I wont settle for this. Lets see how the replacement is, I'll post when it arrives.
Got my replacement.
I got my replacement yesterday. THERE IS NO TINT. BUT. the display has a vertical band that is noticable at time. Well, I can put up with this atleast there is no uneven color anymore. I cannot describe how awesome it feels to use a flawless / near flawless display.

Weird smearing/band on the screen

So, today at night I noticed that when I'm in the camera in dark areas, or in Spotify with a dark background. I noticed that the screen in the middle from the notch till the chin has a lighter colour than the edges. The width of it is about half the screen centred in the middle. It's kinda like how Zack (jerryrigeverything) puts a lighter to the screen and the pixels turn white, but it's not that extreme. It's only noticeable in low brightness, and dark backgrounds, not black. The most noticeable was in video on the front camera. The "stain" has a lighter blueish tone to it.
I'll leave some pictures for you to test them. I know that when I checked on my phone again with light, the stain wasn't there. Test them in a low lit area, and lower the brightness almost to the lowest setting.
The second pic is the front camera (the most noticeable in person). On xda, I find Spotify to the most noticeable.
Maybe I'm blind but for me everything is ok. Maybe you have DC dimming on. Sometimes screen may look weird in dark areas with that option turned on.
Yes this must be due to DC dimming, called anti-flicker in the settings, shut that off and see if it gets better. If you want to show us how it looks you will have to take a photo of the screen with another camera since it doesn't show in a screenshot. That picture is captured before it is sent to the display. The "anti-flicker" setting is known to produce distortion at low light conditions.

Ok. I'll test it tonight. If I use another camera, it'll just blow the image or just won't show up.

I just checked settings, and I have that I had it switched off. I'll see if it makes a difference.

so ive tested it on and off. With dc on, it made worse. So i left it off. The picture ive taken (which was the best i could take) shows a green hue highlighted with the circle. I dont think its the screen protector as it only shows up on low brightness and dark colours, especially grey. Any ideas?
P.s. It looks a bit worse in person than in the pic.
Oh, now I see but I couldn't reproduce it on my Mi9, no matter what brightness or with DC dimming on/off. I'm afraid it may be some screen issue.
That's a dark gray uniformity issue, it's fairly standard on oleds, especially low end ones such as this one. On mine the green tint is most prominent on the top right corner and gradually lessens to the opposite corner. There might be more uniform ones out there but they're like what, 1 in 10 units? If you say yours actually looks worse than in the photo you might have one of the worse ones, but if you can exchange this unit don't expect to get one that's significantly better. To get one that's surely better you have to go for the more expensive ones because those use newer generation panels so the uniformity issues only show at the darkest of grays and and the brighter parts will actually be brighter white which is correct, not green as is the case with the mi 9 panel(pre 2017 panel, samsung stopped having this issue on the s8).

Thanks for the reply mate! Is there any way to tell what specific (display) model do I have?. My box says it was manufactured in July.

Since I never saw this on a Mi9, not mine or any other, I don't think this is true in the case of the Samsung display used by Xiaomi on the Mi9.
The topic starter should contact the seller and get a replacement.

That’s entirely up to you! Can you disregard the distortion you will be ok, but if you find yourself constantly noticing it and being annoyed by it then it will be well worth the hassle I would guess. But only you know what’s right!
Have this on mine, ordered another one in hopes that I can get a better one but it was slightly worse, checked the one they had in a newly opened mi store, that one had it as well to a similar degree. Saying this doesn't happen on the mi 9 is bollocks, all of them have it to some extent, it's a question of how much you're willing to tolerate.
The best thing you can do IMO when you're in a pickle about returning something is do what I said I did: order another one but keep the first one around, compare and just keep the one you like more. That way you won't feel bad about returning the first one and being stuck with the 2nd or just being stuck with the 1st if you don't return at all. Obviously it all depends if you can fit all this into however much time you've got left to return, I was lucky to have 30 days.
Dind!t notice that
