Weird smearing/band on the screen - Xiaomi Mi 9 Questions & Answers

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

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.
Regards
Phil
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.

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] Anyone else have parts of their screen with red tint?

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.

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.

[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.

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.

Screen Issue???

Ok. Is anyone facing screen issue on your P20 Pro? There seems to be a gradient colour shift which is very obvious in a dark room when the brightness is set to low. Plus it has a green hue to it. Have a look at the picture attached. Thank you.

Can't say I've noticed it, will take a look tonight.
Yikes!
I haven't noticed either but I'll also take a look tonight.
Either way i would say swap it out because that is nasty.

What software is used ? i want to try to see if i can reproduce it.
But from what i have tried with text on dark backgrounds my screen does not have that colour gradient shift.

This is Moon Reader+ and the brightness (which can be adjusted from the app itself) is set at 0 and -25.

Ok going by the screenshots is moon+ reader
I tried it for myself and with brightness turned down to zero on phone and in the app i can also see a very slight hue.
But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.
same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.
Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.
Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge
Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.
I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.
Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!
Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.

99% oled screens has this issue. Some are less visible, some more. But every oled screen phone I held had this issue.
Now I have Note 9 and dark grays are uneven too.

I have a Note 9 now too and while it's not perfect it's one of the most even oled screens I've had when it comes to uniformity.

Pixel 4 XL screen has a yellow tint how are yours?

Received my Pixel 4 XL a few days ago and one thing I noticed straight away was how yellow the screen was compared to my Pixel 3 XL.
Only picture I have is uploaded as my daughter has already taken my old phone.
Have you tried disabling Ambient EQ under display settings?

This setting is already off, should have mentioned this above. My display is even more yellow when enabled.

There's a few things it could be, but I feel Google calibrated it this way at the factory as I too noticed my display is warmer but not yellow. Some do say that the yellow hue could also be the adhesive still fully curing. Although I'm not too sure how relevant that is now a days with the newer optically clear adhesives. This usually will alleviate itself through normal usage within a few days to a week. I'm thinking it's more to do with Google's calibration + the panel lottery and you could of gotten a dud. Custom kernel could probably alleviate the issue when you can adjust kcal and play with RGB. But you might want to start a RMA if the issue doesn't go away as I have seen other reports with people bringing up how yellowish their display looks.
Mine is also very warm. Ambient EQ is off and the brightness is high.
It'll be interesting to see if this plays out as "This is how we intended it." or if it's a manufacturing error.

Contacted Google who asked me to check a few options which were already disabled.
Outcome RMA, will check how the new unit looks when delivered.
Same here. It's not a defect, just the way they calibrated it. I actually like it a bit better than the bluish version. That seems to mess with my eyes, whereas this feels very comfortable. Still, it would be nice if they offer us a slider in the future.
I have Ambient EQ on but the short time I had it turned off the colors seemed cool. Closer to a blueish hue.

Mine doesn't have a yellow tint, not even with Ambient EQ on (at least not in the typical environments I use my phone). I really dislike warmer screen tones, so I would have definitely noticed, but mine is leaning more towards the cooler side for sure.
No issues on my white 128 XL. In fact mine looks better than my wife's iPhone 11 pro. her's looks way warmer. I think the display is fantastic on the 4. Best pixel screen yet.
64gb black P4 and I notice a slightly warm almost green tint under 30% brightness. Above 50 it's only slightly warmer than my pixel 3 and at 80+ it's identical
It might have something to do with the refresh rate on the screen. I can notice it shifting between 60Hz and 90Hz. That color shift introduces some yellow from 90 to 60 and removes yellow the opposite way around. You can pick the device to 90Hz in the developer settings, but you're trading off battery life for it.
Yellow here too, off angle it goes white so it's a definite flaw, if it was white straight face on then went yellow off angle this is normal, I'm on my second unit and unfortunately it's worse than my first original, why i hate warm, the people with the same issue as mine will understand, you also lose colour pop when the screen is yellow, simple look at your warm screen look at the colours on text the angle your phone at watch the colours pop better, 100% what people are experiencing is oled manufacturing flaw, I'm still undecided if I'm trying a third but if i do and it's the same or worse again I'm getting a refund until these manufacturers pull their finger out with oled.
Yep, mines super yellow compared to my LG V30, and there's no way to tweak the colors and reduce the red tint.
Its warm but look much better than 3 xl display which has the green tint color.
There's an article on droid - life that says that's the way Google intended the display to be.
https://www.droid-life.com/2019/10/24/pixel-4-lg-display/
There is also a thread over on Android Central with more info and links.
No yellow tint for me, it's quite a cool looking colour. black 64gb model EU.

The 4 XL has a warmer, pink tint. I see more of a blue tint on the 3 XL. I personally prefer cooler tints to warmer or pink ones

Agreed, mine looks awesome to me!
Mine only looks good when the screen brightness is at max. 70% and less, looks terrible. Darker then usual. Yellow/orange. Compared to my Note 10 which is very bright all around. Really want to keep the pixel over the Note but I'm not sure. Have 15 days to decide
