Pink screen - Nexus One Q&A, Help & Troubleshooting

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.

Blueish screen?

I haven't received my Galaxy S yet but everytime I use my friend's I think the screen is just too blueish. Mostly the white parts. And I also think a "square field" is visible all over the screen. Is this because the resolution is too low compared to the size?
The phone itself is great so I still want it, but I'm afraid the screen will make me disapointed, especially since I've read so much about the Super AMOLED is so great.
Are all Galaxy S' screens like this?
What is the "square field"? please explain better.
And let's start from clearing the point of resolution/size-
800X480 is more than enough to go up to 7". If anything, it might be the pentile matrix that the screen uses.
I guess it's these "squares" I see: http://www.engadget.com/photos/iphone-4-vs-samsung-galaxy-s-display-face-off/#3115591
You're probably right that it's more the pentile matrix I notice more than lack of resolution.
I cant understand why many reviews says this screen is very good when it's very noticable.
I've seen mentions of different Galaxy S phones having different colour temperatures, though mine seems fairly cool.
PenTile does, unfortunately, make text less sharp, and there is a bit of a screen-door effect (I think that's the term you're looking for). It's a tradeoff for having a Super AMOLED screen - excellent contrast and very bright, but not as good as a TFT for text. I've become accustomed to it though, despite my misgivings (but a non-PenTile SAMOLED really would be the best screen without question).

What's the good side with PenTile? And yes, I've searched for "screen-door effect" and it seems as if that is what I'm seeing.
Yes, Galaxy S display seems to have quite high colour temperature. You can sort of calibrate it using the calibration app that was developed for Nexus One a while ago and is now part of CM6, but you have to run Froyo, install it manually and lose video overlay, so it's not really usable right now. Nevertheless I've managed to calibrate my SGS to more or less 6500K using it.

Not being able to play back videos and shoot pictures and videos Or, to be precise - you can do all of that, but all you see is white screen

Oh. Well, guess I'm not going with that solution then
But since it can be done through software, does it mean that Samsung could make an update and fix this?
I had this on my old galaxy S and coming from the x10's tft it was painfully obvious the white colour had a blue/green tint to it. I then got it replaced and the tint was still there but not so obvious. Now after a while the white colour looks perfect white. I think my eyes have adjusted or something.

Ok, guess I'll have to wait until I get my before I know how bad it is.
My friend got a blueish Galaxy S I9000. Mine isnt that much!! Next to his looks like mine is Redish, but mine next to my Monitor looks blueish! I believe some Screens have more blue tint than others
Mine is very white. Put the phone on a white screen (using a screen torch app) and the screen looks whiter than a piece of white paper.
Hey all, keep us updated if there's any application that can change the color temperature without affecting the functionality.
I got the phone a few days ago and my friend's is defenitly more blueish than mine. I dont notice the screen-door effect anymore so I'm very very happy with it.
Sent from my GT-I9000 using XDA App
I´ve read something on a German Mobile Phone Review Site (don´t know the which one it was now) and they said, that this is normal, because of the AMOLED Tecnology. They said that the Colors will loose the intensity over the years and as blue is the most energetic Color in the spectrum it looses faster the intensity. That is why it looks now maybe a little bit diferent. After a while it should normalise, because it was planned by the manufactures.
Ok found the Site. Heres the translation:
Higher blue components of the display of the Galaxy S may have been deliberately created by Samsung with the idea that the blue OLEDs are aging much faster than green or red. After months of use should mitigate this effect and color balance to be balanced.

They could do that if they wanted to, yes. But don't expect them to do so, I don't think colour temperature is of any importance to them if it stays within usable range.

Got this tip a while ago on some other thread - you can start Video player, play some video, go to Settings and change the Colour tone to Warm. It stays changed even when you leave the player. It's not perfect, but it helps a bit.

Actually, YES! Your eye do adjust to the white that you are looking at.
You've been doing this all of your life and haven't noticed it. The light in the morning is a very different color than the light at noon. In the morning, it is likely very red if the weather is good, and very white at noon... yet everything looks normal to you... because your eyes adapt to the color.
Adjusting to your screen is the same way. But compare it side by side with another screen and one or the other is going to look "wrong", usually the one you haven't been staring at all day!

Congratulations, your brain has created a special filter, using a process called "adaption", by the human vision scientists, that blocks the screen-door effect. You didn't know it, but your brain created one years ago that blocked out the 'striped-lawn' effect caused by the columns of RGB subpixels on conventional color displays. That 'striped-lawn' effect was just as visible the first time you saw one, but that was likely many years ago.
Okay so this blue tint thing is somewhat strange, still no clear answers.
Some people are saying "this is normal for super amoleds." I have to disagree. If this was normal, then every single Super Amoled would have this blue tint. I've put my samsung galaxy s vibrant side by side next to the samsung galaxy s epic, fascinate, captivate and other vibrants. Some have a blue tint, and others don't. Others have nice rich whites, while some like mine have a blue tint.
Makes no sense, so I'm not buying the "all super amoleds have this blue tint" statement. They don't all have them!
I've used my phone for over 2 months now, and the blue tint is not fading at all. Something else people said. I don't plan to keep this phone for 10 years, waiting for the blue to fade, I want nice white now, not blue whites.
Anyone have any updates on this blue tint some galaxy s phones show?

[Q] Yellowish screen?

Hi there,
The Galaxy Note is my first phone with a LED screen, I had a Desire HD before.
Since I got my Galaxy Note, the screen seems a bit yellowish to me.
When you tilt it a little bit to the side, you see the while colors becomes more white, but when you tilt it back, so the screen is right in front of you, then the white colors looks a bit yellowish again.
Is this normal for a LED screen?
I don't like the yellowish tint at all, but for the rest the screen looks amazing.
Thanks for your answers
Hmm I don't really notice any sort of yellow tint on my screen but then again I'm not the most color observant person . What you can try is go int settings==>display==>screen mode and change it from standard to dynamic or movie. I have it on dynamic and love it.

Yea I already tried dynamic mode, it makes the yellowish tint a little less, but it's still there.
You can notice it by yourself by tilting the phone.
Just put something on your screen that has a white color, and watch the screen from the side, it looks much nicer then.
Ohyea, by the way.
You can also notice the yellowish very good if you put the screen mode on movie
Just got my Galaxy Note N7000 today and noticed the same issue on mine. Tilting the screen slightly makes the whites look pure white while in its normal position the screen looks kinda yellow. I am not being able to understand if this is a faulty set or not
SAMOLED screens are supposed to have superior viewing angles, it is believed that the Oleophobic coating is causing the green/blue/yellow tinting that you see when the phone is tilted ( well in your case its a direct view ) my first screen had absolutely no color shift even at the most extreme angles, the new one I have now has a blue tint unless directly viewed.
The norm is supposed to have great viewing angles and only shift in really extreme and non usable angles.

Well, you don't have to be upset like that.
What I'm trying to say is that if you tilt the phone, it has great colors.
But when you look straight onto the screen, you see a yellowish screen.
Your conclusion is that the viewing angle are very good, and only shift in really extreme and non usable angles.
Looking straight onto the screen should not be a non usable angle.
And Im not the only one who's saying it, but when you tilt the phone, the colors looks much nicer.
Im not upset, I just found it amusing why it was not understood right off the bat.
Have your screen/phone replaced, thats clearly a quality control issue.

He does have a point normally a screen comes in warm,cool and neutral depending on the factory calibration. These things can be normal as long as the user accepts them to be.

No problem, Keep us posted on whatever you decide.
I've had four blue Galaxy Notes and one white and they all exhibit varying degrees of tint with some less noticeable than others. Some have a more warmish yellow tint while others are cooler with more of a blue tint. It was the same way on the Galaxy S2. The best you can hope for in getting a replacement is one that has a tint that's less noticeable or if you prefer a cooler tint to the warmer tint.

[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.

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.

Look for it... there are no perfect phones hahaha.
But congrats if you don't get annoyed with your new phone :good:

[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.
