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.

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.
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
Looks like crap.

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.
Hey guys, I've got a tianma display with the infamous pink tint from angles. I compared it with a store unit and my unit's display quality is subpar. The brightness, contrast and viewing angles all are bad compared to the store unit which had SHARP panel. Tianma owners, did your unit's pink shift improve? How did HTC respond with your pink shift if you contact them for this problem??

So the pink shift when viewing off angle stays. It's definitely not glue, rather something to do with polarisation or a coating on the display. That being said, the screen on my phone has gotten much better when viewed straight on; it always used to look rather pink when compared to my iPod Touch 6g (which is generally well calibrated) but now just looks a little cooler which is fine since the iPod is slightly warmer than neutral anyway. The screen has not gotten any brighter, viewing angles are better but still slightly pink past ~60-70 degrees, especially in portrait and much less so in landscape. It took around a month to settle down for me, I've had the phone for two months now and really like the display. I do a lot of photography work and know what a well calibrated display looks like and the 10 is pretty spot on. As for brightness, it's not the brightest always visible even in the Australian summer, just make sure power saver isn't on since it caps the max brightness considerably.
When displaying a pure black image on the p2 the bottom left 1/3 of screen has a slight yellow glow to it when you look at it in a dark room. The same area looks more warmer than the rest when displaying grey. Anyone else noticed this? From searching around I've seen complaints about similar issues on some other amoled screens on nokia,oneplus, lg etc. So much for amoled showing pure black, if you want that it looks like you have to get a samsung phone. It's still better when compared to IPS but the uneven tone can be annoying.
