The screen on my 8.4in Tab S is bugging me, is it just me?
With all "super enhanced" colour settings set to plain and boring colour, I keep noticing a slight green tint in the central area of screen when viewed square-on, it's very subtle and seems more obvious with text on the screen, e.g. the Tapatalk forum listings. Also when viewed from an angle the display takes on a slight blue tint, despite reviews saying how good the angles are, it seems worse than the LG G Pad.
Is this just a feature of AMOLED displays or could it be a faulty unit (how?)?
I don't see it. Sorry.

There shouldn't be any differences viewed at any angle with this screen. Try this... in bright sunlight, with the screen off, look at the screen on an angle. It should look a uniform color - actually almost exactly matching the titanium bronze bezel... just to make sure there is no physical defect.
Something to note - if the screen is OK, it could be your eyes (not joking). The eyes can play many tricks - for example, seeing a lightly shaded box with text on a piece of paper that is only black and white - the box can appear to be shaded slightly red. That's one example, but there are many. And with the resolution and technology of this screen, there are no imperfections to draw your attention, like staircasing, blur, backlight irregularities, that you are used to seeing. It is a bit confusing to our physiology, and our brain does this thing called "patternization" that can contribute to us truly seeing something other than it is. This seems to be more subtle, yet more frustrating on a display that is so close to perfect.
I'm not saying that there is something with your eyes specifically. It could certainly be a defective screen. One way to find out would be to take a look at someone else's - also, if you have another decent camera, you can take a picture of the screen and look at the picture - that will usually confirm (or not) whether what you are seeing is there. Like I said, it's not you or your eyes I'm dissing. These are things I've picked up on over the years. In fact, it could ONLY be my eyes. If that's the case, I'd probably rather not know.
You can also use a colorimeter and software like HFCR to get the discreet measurements from different parts of the screen. When I have done this, I've found that there was no real difference in chromacity. Of course, that has always made me walk away thinking that the colorimeter must not be accurate. So human.
I would definitely be interested in your feedback about what you find because I've obsessed over high resolution displays trying to figure out what is real and what I'm imagining... it's an active area of interest for me.

Yes I have also noticed this. I've seen these green or pink tints on all the amoled devices I've owned. You need pretty good eyesight to be able to notice it. You shouldn't be bothered by it, they're all like that, if you can see it. But you'll get used to it.
I probably will not get used to it...

Thanks Freshman206 and SrAdama, glad (?) to hear that it's not just me, I've had the tablet just over a week and still notice it. Any slight tilt and the colours appear/shift, green, pink and when angled beyond what I'd consider normal, blue.
Have photographed it and will have another go at getting it clearer but by winding up saturation the effect becomes visible in the photos (on pc).
I'm now trying to decide what to do about it, I have an LG G Pad which doesn't annoy in this way, though it has just gone away for a warranty screen repair for bright spots (not stuck pixels)!

It is probably the antiglare coating you are seeing.. If you have the coating on your glasses and check them out, it will do the same thing as your tablet... I also noticed it appears to have a anti fingerprint coating on as well, very nice indeed :>
In shops I also have compared 3 different Tab S.
All had an immediately visible green tint, white looks not white but greenish and a bit "washed out".
I find it a bit surprising that with other devices, when they have a tint (like the yellow tint of the Xperia Tablet Z), people complain much, while here, with this really apparent tint, people tend to say: It's normal, get used to it...
I would never buy a Tab S, just because of this tint and because of the, compared to other devices, low maximal brightness.
These devices are overrated.
I ran a poll in this forum as to whether people were satisfied with white reproduction on their tablets or not. Out of 15 responses 12 were satisfied.
We have heard reports of manufacturing defects such as yellows screens, muddy splotches in the middle of screens, loose creeky backs, warped backs and excessive lag/stutter.
These are not "normal" for this tablet but represent what may be a bad run of tablets that made it out of the barn. If you are experiencing the issues suffered by the OP, I suggest you seek a replacement unit. If you have observed similar performance from other tabs in the same store that would make sense as they are likely from the same faulty production run.
When operating normally, white should be white on the Tab S. For myself and the large majority in the poll, this is the case. I have also not read any reviews by professionals mentioning this discoloration and believe me, if CNET or THEVERGE had something to rag on the Tab S about they would have.

The average rating by actual owners of the Tab S 10.5 bronze at BestBuy is 4.8 out of 5 stars with 53 reviews.
The average rating by actual owners of the Tab S 10.5 white at BestBuy is 4.9 out of 5 stars with 36 reviews.
You will see very little if any mention of an issue with yellow or green discoloration. I'm sure you are seeing what you are seeing but the problem does not appear widespread.

I just took a picture of a webpage with a white background on my 10.5 and sent it to my laptop which has software that measures colors.
The website background from my Tab S 10.5 measured at 255:255:255. That is pure white. This was a photo and not merely a screen shot.
Saw the 10.5 inch and 8.4 inch models together on display in a shop. The 8.4 inch version also had slightly yellow tinted whites when looked at directly, not as bad as I was expecting though. The 10.5 inch model had no yellow tinted whites at all, when looked at directly or tilted.
Mine has pinkish tint at the top visible when everything is white especialy when reading wikipedia

so when i switch screen mode to amoled basic, my screen have yellow tint (like warm color) and a little washed out color, is it normal or just my unit?
because when i switch screen mode to amoled cinema, everything looks saturated which is i think okay...

Yes the Basic profile is meant to be that way its not the screen problem being discussed here, if you wanted an accurate image then Basic is the closest of all the profiles. If Basic looks washed out to you then your used to looking at an oversaturate screen, if you were used to looking at calibrated screens then all three profiles would look over saturated.
I had the 8.4 and just returned it. I also had the greenish-blue tint when the screen was even just slightly tilted. More noticeable indoors with brightness set to below 40%. If I had the tablet flat on the table and walked across the room, I could see it too - screen only looked good if looking at it directly in front of you. As others have said, I think it's probably due to some coating on the screen, which explains why it would be more noticeable with the screen brightness set lower.
I've checked out a few display models at stores, they all basically look the same, though some were slightly worse than others. That being said, the 10.5" ones I saw don't seem to have this problem... if they do, it's definitely not as noticeable. Not sure if it's just an optical illusion or what, but the 10.5's look OK. I'm going to go buy the 10.5 one today, mainly for the size. I'll post again if there are any tints on the screen.

The problem was a green tint in the center when looked at head on not at an angle, seeing shifts in color when tilted is normal for this tablet. I would have kept yours if it was fine straight on.
My 10.5 had greenish yellow tint when looked at head on exactly the same as the op.
http://forum.xda-developers.com/galaxy-tab-s/help/normal-screen-faulty-t2822471
I was gonna return for the 10.5" anyways, the screen tint wasn't part of that decision, but I certainly won't miss it, heh.
Mine it is extremelly yellow! I hate this bug... It happends to me every 10 minutes, i need to restart every time to revert this.

Can you explain to me how i can do the adjustment?
Do i need to root the tablet or from the menu? (The only tweak i found from menu is the color profiles : amoled basic, amoled cinema, etc) I have a sony xperia phone and it has an option to adjust the white balance with a slider!
Thanks..

Today I got two 8.4 Tabs, both wifi only versions in my hands and I was impressed, that the white color was different. Sadly, the whites on mine were a little bit more yellowish, warmer, and a little bit dirtier. Is this normal for samoled?

my experiences tell not all screens produce the same color, some are yellowish, while others are slightly blue, which can make white color a bit grey, etc
once i wanted to buy a note2 but i found its so bluish and therefore no deal
so each time I buy a phone, esp amoled, I will check the screen (and other things of coz) before I pay
I currently have 2 Galaxy Tab has 10.5 inch at home and deciding which one to keep. The main difference between the two is that one has a newer build date and love one screen seems to be a little more orange brown tint to the white versus the other tablet seems to be a little more blue yellow intent. Other than that perform identically however I did notice that when I run the CPU temperature app that the one with the yellow blue tinted screen seems to run a few degrees cooler most of the time except when using Chrome when where the other tablet seems to run several degrees cooler but only when JavaScript is activated.
One little trick in addition to adjusting the temperature using the adaptive display were changing from AMOLED basic to Evelyn cinema to make it cooler, is to go into the accessibility settings and then go into divisions section and then go into the area where one can do a test of their color as if they needed adjustments because of their own visual impairment. If you run that test and intentionally miss order the color tiles, and then will activate the option to allow you to adjust a slider which can further give you A white screen that seems to be somewhere in between the really blue display and the really warm AMOLED basic

Old thread i know but i just wanted to thank you for that tip Canadoc. I've been struggling with the excessively warm image from my Tab S for a year now and while putting it into "Cinema" mode fixes the white balance it also destroys the contrast by making all subtle dark detail just disappear. This accessibility method has given me much nicer whites without affecting the contrast other than removing the orange haze. I assume the colours are going to be slightly different now but i can't say i've noticed anything there. I wish the Tab S had the same display options as the Galaxy S5 has where you can choose the cooler white level without hammering the contrast too. Maybe it's something Samsung do in order to protect the lifespan of the blue sub-pixel?
So thanks again
When the tab s 8.4 came out the screen quality was a bit variable, but it's been months since I have have read of anybody having a problem, see if you cab get a replacement.

Mine's the 10.5 and this is the second one i got which was exactly the same as the first one in screen tone.
I always wondered if third-world country`s got B-C grade stock, as the consumer protection can be poor or non-existent, maybe it`s cheaper for the re-seller to buy this lower grade stock with screen color problems ect, I dont know?

UK here and bought from John Lewis. I've heard plenty of issues with screen temp on these ones so it's fairly common. Just using it this morning and thinking it perhaps wasn't quite as white as i'd like it and checked the settings to see if it was still in the proper mode and it was, switched it back to the old one and don't know how i ever lived with that brown tone!
Under different light sources it can take a few minutes for your eyes to adapt to the screen, so white can look a little off while this is happening, as the human eye will normally auto white balance anything you look at.
Does you screen when browsing with a white background at night, but not totally dark still not look perfectly white after a few minutes of looking at the screen.
Everybody seems to see colors slightly differently, and some not so slight, did you see the white/gold blue/black dress debate.

No it never looks like clean white to me unless i tilted it slightly back or forward and then i could see the tone shift to a cooler temp. I do keep the brightness down to under 10% most of the time and that doesn't help the white level either.
I can't say i ever understood the dress image, you can factually measure and define the colour on that one so i don't know why people were confused.
Have you had anybody else check your screen, do they see the same problem, though at 10% brightness the screen is never going to look really white, I always keep mine on Auto -5 , I have the RGB sensor set on Auto i cannot even remember what it`s really called as i have never changed it, but in Auto it is supposed to keep the whites looking white, what is yours set too.

Warm colours
My tab s 8,4 screen has a brownish layer, which makes whites mor brown and the colours less sharp. But when I put pressure on my tab, the "layer" goes away.

Anyway, i haven't had anyone else look at mine but i don't need anyone to anyway, it's a very overly warm tone. I've never used the RGB adaptive sensor thingy as it only works in a few apps that i never use anyway.

Do you see a much whiter tone when you choose Cinema mode? If so and you like it then you really should try the method in this thread to keep it without also cranking up the contrast.
Hey everyone,
I got my black AT&T Note 4 earlier today. I noticed the lower half of the screen is slightly darker, and has a slight pinkish tint on a white screen.
I do notice it in some apps, like Kindle when readinga book. Top of screen is slightly brighter, and when background is white there's a very slight pink tint.
Is that normal? Or should brightness be uniform and no tint?
EDIT: I added a photo. It's not a good photo but you can see how one side is tinted differently. In the photo the brighter top looks greenish but in real life it's not green. You can also the slight pinkish tint in the bottom half, which is the left side of the photo.
I wouldn't want to comment based on the image you uploaded directly since how a camera captures a digital display is much different than what the naked eye will see. If the picture on the panel is not consistent and appears polarized in any way, I would consider that to be faulty. Get it replaced.
Galaxy Note 4 (pink tint lower screen)
Hi there,
I have also noticed a pink tint on the lower half of the screen on new Samsung Galaxy Note 4.
As i intend to do a lot of drawing on this device the tint is unacceptable.
I wonder if there is a way to calibrate the display?
I had this issue with my Galaxy S3 display. I had at&t exchange it.
Have this same issue on my Note 4. Posted some pics over in the thread on this topic for the Note 3 before I thought to check here. Basically there's a brightness and gamma gradient from top to bottom. The top half is perfect and the bottom half gradually fades to a point where you lose the first 8-9 squares on the lagom.nl black level test.
This one emphasizes the black crush, which can be visible in video content on a dark screen (and makes dark colored backgrounds fade to black towards the bottom):
And here's one on a white background. At first it seems like a white point issue (which I would tolerate since it's common on IPS as well), but it's a brightness gradient:
Between this and the fact that AT&T disabled the slider for auto brightness I'm a little frustrated with this supposed best smartphone display ever (I realize this second issue isn't Samsung's fault, but the auto brightness is unusable without that feature). I bought the phone at Best Buy which is mostly out of stock right now so an exchange isn't likely, assuming they even take this seriously as an issue.
My note 4 does not display this issue.
No issues here. Display looks very consistent.

Have you tried a dark background in a dark room? For me it wasn't that obvious until I did this (was messing around in Sketchbook). If the majority of screens are better than mine I'll definitely be trying to get a replacement as this is bothering me.
I just installed Lux to resolve my backlight issue and its settings menu background fades nearly entirely to black at the bottom.
*Edit: So far it sounds like this is an anomaly. You would expect places like Anandtech to report on it if they'd seen that amount of variation. I'm going to have a good time trying to convince someone at BB that this is a real defect though.
Erica Griffin talks about this issue in her Note 4 review, around the 20 min mark: https://www.youtube.com/watch?v=-OyNWrQJzMY
I got a replacement and it's perfect. No pink tint.
So, if you have the tint return it. Not all Note 4s are like that.

Thanks, that was quite helpful. I think in general it's easier to trust reviews on retail-purchased devices over mainstream reviews with PR department selected units.
I went to BB today and looked at the display units. All perfect, but then that's not surprising (every company gives their display/review units a second QC pass, even Apple). I'll probably head to the only BB in the area that has units tomorrow and see if I can do an exchange. As long as they don't make me sign one of those "no more returns" agreements I've heard about I'm willing to take another shot in the display lottery.

Good to hear! I'll post my results after my exchange attempt tomorrow. Aside from the gradient I am impressed with the display. Not as bright as LCD in daylight, but I was drawing on a black BG last night and noticed that it has deeper blacks than my Pioneer plasma.

Fingers crossed for you to get a nice one like mine.
Yeah, the blacks and colors are amazing on the Note 4. The whites are not as bright as the iPhone 6+, but they are fine and way better than whites on my Note 2. In all other respects the Note 4 screen is overall better than even iPhone 6+'s excellent LCD.
One minor disappointment is the very high resolution has made some emulators dog slow as they attempt to render at full resolution, i.e. PPSSPP and ePSXe using ogle renderer. Hoping the devs find a workaround, maybe rendering at half or quarter rest instead - that would still be higher rest than my Note 2 at full rest. :laugh:
What's the color of your device? Anyone have this problem in the white version?
my note 4 has pink tint
I have the same problem on my Verizon white note 4 but on top half of display. Replacement should arrive by Friday :/
You can replicate this by looking at the screen at an extreme angle, obviously the ones that see green and purple straight on are screen defects.
I have a white version and whites are perfect and too bright at high setting. I keep mine half way. The whites are better IMHO than the iphones. The colors more vibrant and, the sharpness is ridiculously sharp. I dont see how they can improve it. I only thing there should be a waynto adjust the color saturation, because basic mode doesnt do much on mine.
My Note 4 has the same issue. It almost looks like the while balance differs from top to bottom, but it is really the brightness that is different.
This is a photo of my Note 4 showing a solid colored image at #030303 (very close to black). It shows how different the pixels in the bottom and in the top emit light.
Image can be seen at 1x.com/tmp/uniformity_note4.jpg

similar problem
I have a similar issue, though mine is brighter on the right side than it is on the left. Very noticeable with dark background in lower light situations as someone else mentioned.
I've had 2 Oneplus 3's now, and am now in the process of sending the second unit back for a replacement.
This because the screen wasn't functioning properly, there was lightbleed on both and the screen had a green tint on one side and a red tint on the other side.
Has anyone else experienced issues like this? Is it a known problem, big or small? Or am I just in really bad luck by recieving a bad screen 2 times in a row.
No issue here. Wish the screen was brighter but at least its the same as my g4

The problems you're describing are physically impossible on a Super AMOLED display... and to say that it has happened to both OP3s you received is just as absurd. The pre-applied screen protector is pretty crappy, but I mean c'mon... Are you one of those guys who returns things with the smallest imperfections, or perceived imperfections in this case?

Woah there, I have no idea how it is possible to have the problems I have, I know that with lcd sometimes the glue causes the device to be lit unevenly, don't know if that could be the case, but it seemed a little off. I tested this using this video on full brightness: https://youtu.be/vu0mQa2EpS4
While going from. Grey to black, the pixels should all turn of at the same time, or at least, that's how I think it should be on amoled. But this wasn't the case on both devices.
As for the different tint problem, that does bother me a lot more, reading Web with a changing color if you read from left to right isn't that good for the eyes or at least It bothered me.

Do you have any picture of the defect. So far, your issue is uncommon one for OnePlus 3.

Here are some pictures, it's quite difficult to recreate on camera like I see them but this gives a general idea of what my issues were with the first device. The first being the screen tint, on the left of the screen it seems to be more red and on the right more green, while this is a Grey background at about 50% brightness. The second is how the screen is unevenly lit while on a solid Grey low brightness background.

I just watched that LCD test video and firstly my eyes hurt from the bright white light secondly I am quite picky and having come from the g4 which I thought had a great screen (few bleed issues though) I am quite happy. I couldn't see anything at all on my unit like you have so maybe it's device specific?
I have noticed this weird thing though and it's when I use MX player pro to watch films. I have been watching the dark night for like the 20th time on th op3 but do notice the skin tones look a little warm and when i increase brightness it gets worst. I think this is a combination of the pentile display and the AMOLED screen with a lower resolution than we would like. I am sure I remember my galaxy note 3 and wife's s5 looking like this also but could be wrong.
Overall it is strange using g4 then using op3 it's hard to explain but they are just different not just LCD / AMOLED but the calibration also. Love the blacks though it's like the phone is off when the screen goes dark. Nice.

So the screen turned black fully at the same time, well there's a logo on screen, but apart from that all black?
I know what you mean by that, I think thats in all screens, not sure, but I had it in both screens but also the problems occurred on them too, maybe that's a feature, I at least won't mind at night when the screen is that low and a bit more warm toned. I saw it on a selfie I got on whatsapp, at night when I got it, I saw her face normal, but when I set the screen brighter, I also saw that the photo also had a background! which was invisible and dark on the lowest brightness.
no issues
Didn't see a logo. Must be blind

The problems you're describing are physically impossible on a Super AMOLED display... and to say that it has happened to both OP3s you received is just as absurd. The pre-applied screen protector is pretty crappy, but I mean c'mon... Are you one of those guys who returns things with the smallest imperfections, or perceived imperfections in this case?

Smallest imperfection? He uses the screen all the time and notices that all the time, how is that small imperfection? Also amoled screens are known for the issues he described. All screens have that issue. Just people like you are not good enough to notice it while others notice it easily.

This logo, not that important, but YouTube shows it really need to turn that off sometime.
Honesly, i don't expect the screen to be yellowish like that, but it is a bit yellowish only if i view it 90 degrees directly. If i view it from the side, the screen shift to blueish colour
Your guide is so useful since i am a new Samsung user, thanks
What phone are you coming from and what other electronic screens do you have around? The S9 is calibrated to 65K (see color temperature) and can appear yellowish if you are used to other screens that defaults to higher color temperature (including most iPhones/iPads). In that scenario there is nothing wrong with the screen and your eyes will get used to the new white pretty quickly.
On the other hand if your screen appears severely yellow compared to other Galaxy S9s' (e.g. check store models) then you probably should 1) get yours replaced from where you bought it, or 2) contact Samsung tech support.
Thanks for your reply, i come from Xiaomi Mi4i, it is cheaper phone by a large margin, but i don't know why the white seems nicer. Oh and i have another question , when i tilt the screen to the side, the white switch to blueish colour and it seems nicer than staring at the phone on 90 degrees, is that sAMOLED thingies ?
As to your latter question, yes that is an AMOLED thing. As to the first, do this simple test: Go to a room with no direct sunlight and no other electronical screens, where you can just look at the phone's screen without distraction. Use the phone for 10 minutes or so @50%+ brightness as you normally would, without worrying about 90 degree tilting. Do your eyes see the whie as yellow? Or have your eye adjusted to the new screen and white now looks white? If the latter, then your screen is likely just fine.
If you want to see what yellow-white looks like, try "Blue Light Filter." That thing does turn the screen yellow. (maybe you have it enabled now and that is why you are seeing yellow? )

I have no first-hand experience with the Mi4i, but judging from what I can see in videos its color temperature is at least at 7500K, meaning it has blue-ish white.

hi im having the same problem with my s9 brought it yesterday and youtube videos look horrible discolor yellowish
had that issue with my first S8+. compare it with store models to check. my replacement was much better. now I have the S9, and it's definitely not yellowish. it's such a good white balance actually. so if you're not happy with it, exchange it while you can.
Thanks for all of the reply appreciate it, i check to the store and... turns out it is the same white as mine, still like the bluish white on my former phone. Compared to the note series, the note has better white. I tried to change the screen settings to cool, but it appear greenish. @lopri Thanks for the research on Youtube, respect for the additional research
I already calibrate the screen to cool, to overcome the greenish, i turn down the red and green color, now it is better but still can't resist my old phone blue-ish white.
When watching video on youtube it turns orange-ish, it might be because the video enhancer <- Now this is the problem
Before i got the phone, i have an impression that it would have a very great display... , but now it feels -- only good, but not overwhelmingly great like the review said
"ยท Record small Shifts in Brightness and Color with Viewing Angle, including White."

Adjust the display settings. Put display warmth to the highest then reduce red and green to a quarter.

it's possible the store display also has the same issue. mine is bluish white. I went through the same thing as you with my former S8+, in that even changing settings to cool, didn't make much difference. the replacement I got after confirmed that it was the display itself.
Yep, comparing the S9 and S8 side by side the S9 has a yellow tinted screen. The whites aren't as clear even after adjusting the colour settings.
