I did had the feeling too for a while lol, was quite surprised I dint had to visit their service centre even once nor I have to now anytime, my issue (pink tint on right side) was quite visible on every app I use except on colourful backgrounds, n it was too annoying on my eyes so I'll keep getting it replaced unless I have a screen which is flawless or somewhere near where I cant notice any issues, I did kept my Note 3 for a bad yellow tint issue for 1 year but not anymore, makes no sense to pay so much on same company which is unable to provide a good quality product. tho lets c how many replacement I'll need to face lol.. and good to know you're happy with yours, I am waiting to see when my turn comes. :p
[Galaxy Note 4 General] gabrielgon:
I feel the same way man. I was going to have mine repaired as mine times as needed, but this was going to be a real pain in the a**! I wished so many times to get a good screen and got lucky. Hope you get yourself a perfect unit soon!!

Another lovely screen delivered by samsung

Right back to the shop for a replacement

F - version, vietnam-made

That looks weird... is that screen supposed to be all black ? Cant see it clearly form the pic.
[Galaxy Note 4 General] Menchelke:
Maybe it is a blessing to have eyes that don't see all the imperfections, or a mind that drills in and obsesses over it.

With whatever vision I have, my screen doesn't appear to shift colors, maybe very slightly, at like 178 degrees, but that isn't how I use my screen, so it's a non issue. From any normal viewing angle, I see no color shift. Just a shift in the brightness, which is to be expected as less light is going directly to my eyes.

Anyways, I'm not saying that you aren't seeing real issues, but, when a person says "I got a perfect screen" there is no point for you to quote them, and say, nah, you got an imperfect screen, your eyes just aren't good enough to see it, or you aren't looking hard enough" Even if that is true, just be like, Congrats! and move on with your quest to find the perfect screen for yourself.

Remember, beauty is in the eye of the beholder.

My screen is mostly even, but I notice some things are a bit off. For instance, when I bring up the keyboard in landscape mode, the keys on the left side are slightly darker and a little bluer than the keys on the right. The screen is definitely darker along the top. I'm still trying to decide if it bothers me enough to return it. Usually I'm very picky about screens, but over the years, I've realize that I've never seen a screen that is completely even and perfect and repeatedly exchanging phones is really frustrating. There's always something not quite right. Everything else about the phone seems to work well. Well, the camera is pretty bad in darker shots. They come out a bit yellowish. Other than that, though...

Just not sure what to do. I have until Saturday before my 2 week exchange period is over.
[Galaxy Note 4 General] wm2001wm2001:
Ur lucky enough having an exchange period. In Australia we have no such a thing. I brought mine to a Samsung experience store and as expected, the staff insist that he didn't see my problem. Apple seems to be the only company who has proper warranty policy.
[Galaxy Note 4 General] ALESSIO94x:
The screen is amazing, but I have a little problem... When I am outdoor and there is a lot of light (and the screen is set to the max brightness), on white images there is a sort of blinking of the display. It's only my unit? Thanks!
[Galaxy Note 4 General] carloshdez:
Grey background with minimum brightness... real life use is not that exaggerated, but as I use it mostly in dark environments, it really annoys me.
[Galaxy Note 4 General] TML1504:
[MENTION=3262159]Menchelke[/MENTION]: you are right, but the problem is if you realize that there are "good" screens around, you want to have one for your 700<€ investment. especially when you see that there are huge differences when you compare units side by side. according to your statement you must have been lucky with your screen...

but as i said, i agree that noone has to talk other people in "your screen is perfect? then your eyes are bad!!"

[MENTION=1017517]AleSSi0[/MENTION]94x: this is due to PWM, google for it, and there is even a dedicated thread here on xda\note4 on that topic.
[Galaxy Note 4 General] naimmkassim:
Does this means we should not use the default vivid modes for long time??
[Galaxy Note 4 General] usmaak:
Interesting response.

I've been through all of the possible screen issues that Apple devices have between the iPad 2, iPad 3, and Macbook Air. I gave up on the iPad 2 after two exchanges. It took me several iPad 3 exchanges to get a screen that wasn't a complete disaster. It is yellowish on the bottom. And my wife's iPad 3 has a darker strip along the left side. I exchanged the Macbook twice for screen quality issues. Through all of the Apple devices that I've used and exchanged, I have never found a perfect screen. Though some will argue with me, I don't think that there is such a thing as a perfect Apple screen. Some are much better than others, and some are complete disasters. It's all in what you can live with while using their products. Show me a perfect Apple screen, and I'll show you why it's not perfect.

Between my wife and I, we've had three Note 4s in the house. My first one had other issues, so I exchanged it. The screen was pinkish at the top, and a little greenish at the bottom. Overall, my wife's Note 4 is brighter and yellowish, but darker at the bottom. She doesn't notice things like this, and pretty much thinks I'm crazy. The S3 that she used for the two years prior was very noticeably pink on the bottom third of the screen. She was able to see it, but she still used it for two years and never complained. I wouldn't have even left the store with such a bad screen. My Note 4 is darker at the top, and lighter at the bottom. On a grey screen, I can see a couple of slightly darker bands toward the middle of the screen.

I don't think that any of this affects my day to day use. If I am being critical of the devices, then I see the flaws. In my case, when held in landscape mode with the power button up, my keyboard is darker on the left hand side. If I look at a white screen, I can see that the screen is slightly darker along the top. If I turn off auto bright and bump the screen brightness, these effects are mitigated somewhat, but do not go away completely. If I just use the device as it's meant to be used, without looking for the flaws, then I don't notice them.

I really don't want to exchange it, because there's no guarantee that what I get next will be any better, and it most definitely could be worse. One thing that my phone doesn't have is the narrow viewing angle issue. And that would bother me much more than these other issues. I guess that it's just getting past knowing that the flaws are there when I use the phone.
[Galaxy Note 4 General] naimmkassim:
Since most of user here are afraid of getting new device with more worsen screen or afraid of others defect, then u all should send it for repairing instead..request the center to change the screen..thats what i do..as long as its under warranty..?
[Galaxy Note 4 General] TML1504:
no. this has no impact. it only makes things more or less visible, in terms of screen issues. this could make a yellow tint (when viewed straight on) less visible, but when tilting there are still huge differences between different devices...
[Galaxy Note 4 General] wm2001wm2001:
The yellow tint was driving me crazy but now I guess I'll just get use to it.
[Galaxy Note 4 General] t1337dude:
As long as the screen uniformity is good - there's not much to complain about. We simply don't have the technology for perfect viewing angles, so there's no reason to complain about color tinting, just about any screen will exhibit noticeable differences in color and contrast at an off-angle. Some more than others, maybe, but I don't see it being useful going through the headache of exchanging your phone for another screen that is just as likely to exhibit the same "issues".

If your colors aren't uniform and there's anomaly's head-on, then yea, I'd try to get the phone looked at, because that shouldn't be happening.
[Galaxy Note 4 General] usmaak:
That's the thing. On the three notes that I've had, it is most definitely not uniform. Mine is darker at the top, and a little yellowish at the bottom. My old one was pinkish at the top and greenish at the bottom. Wife's is darker at the bottom and quite yellowish at the top. The display models in the stores that I saw also have noticeable uniformity issues. Pictures and stuff look great. White or lighter colored screens really show the uniformity problems with these phones. I have a dark grey image that shows yellow at the bottom and is much darker at the top. The thing is, how often will I notice these issues? How often am I going to be looking at a straight white or grey screen? Of course it's more noticeable when in landscape with the keyboard up (left side looks bluer, and right side yellower), but it's unlikely that I'll ever use the keyboard in landscape mode.

It's a tough call on what to do. If I return it, I could easily end up with something worse or something that has other issues. I'd even return it for the poor quality of indoor pictures, but my first one had the exact same issue with indoor images that are way too warm.

All of this yellow tint stuff brings back nightmares from the iPad 3 release. :D
[Galaxy Note 4 General] naimmkassim:
If u are a kind of people that use a fb application a lot, than u will see the defect everyday and that is annoying to me!! I heard lolipop use much more grey color for background, its going to look more uglier soon..
[Galaxy Note 4 General] wm2001wm2001:
Now I don't know what to do.. As I keep getting annoyed by the yellowish tint when directly looking on the display. Problem is, what choice do I have other than Note 4? I don't want iPhone nor Windows Phone and Samsung has crafted the Note 4 just right ,except the display...
[Galaxy Note 4 General] naimmkassim:
Yours still under warranty right?? Go for it..perfect screen is out there..u just need to be a little bit aggressive..one of my friend did see the manager on one of service center here..just to fight for his right to get a better display..firstly he demand for an exchange unit, but because sammy here did not practice for an exchange unit, his end up they repair the unit..they said, they just calibrate the display as to reduce the max brightness that causes the yellow tint on all part of his screen..my case is different than him, mine is only part below screen is pinkish which required changes new screen..
[Galaxy Note 4 General] wm2001wm2001:
Thank you for your reply.

Problem is, I've checked some demo units and they all seems to have some sort of similar yellowish tint problem at direct (90 degrees) viewing angle. Now I'm thinking of refunding the device (and service) and grab another one. Kinda frustrating for sure.
[Galaxy Note 4 General] gass88tp:
Hi guys, do you try "SCREEN TEST AND FIX" on play store? Is it Good? ??
[Galaxy Note 4 General] usmaak:
I keep going back and forth about it. I looked at the Droid Turbo (Verizon), but just didn't like it. I was also interested in the Nexus 6. The thing I like about the Note 4 is that it's not just a standard phone that's made larger. There are lots of things the Note has, that no other phone has. I don't want to give up on that. I've played the exchange game with electronics before. Sometimes it works out, but usually, at least for me, it is a disaster. I'm afraid that if I bring the phone back, I'll get something with a worse screen or some other problem. My wife's Note 4 has less of a darker area on her screen, but much more yellow, and that screen is way better than the one that she had on her GS3. My original Note 4 that I swapped for this one had pink at the top and green at the bottom. That one was worse than what I have now. At least in my experience, screens with flaws are not uncommon. Trading will probably give me a screen with either the same issue or other issues.

So right now, because everything else works, I'm inclined to keep it. If the screen really bothers me in the future, I might pursue a screen replacement with Samsung. If they deny that, then I'll just learn to live with it. The problems with my screen are most visible on solid gray backgrounds, which I'll probably never look at.
[Galaxy Note 4 General] naimmkassim:
I think you will have to look at it for gray background once lolipop come. Dont giveup..make sure they know, not just u have this issue, all of us here do also [emoji13]

After Samsung puts its Touchwiz on top of Android L, there's no telling what it will look like. I can see it being a problem for those that root and install other ROMs. I'm not sure how much of a problem it will be for those using Touchwiz. Hope not, anyway. :)
[Galaxy Note 4 General] wm2001wm2001:
Exactly, and I've heard that the AMOLED is more likely to have a yellow tint as it's the price for better color saturation and black performance. However I'm gonna quit as it annoys me so much. I may pickup a LG G3 and use it for a while before getting another phone. I hate this that Note 4 is almost a perfect phone, literally one last step to perfection.
[Galaxy Note 4 General] Magnesus:
High color temperature gives blue tint, low gives yellow tint.

What you call yellow tint is usually a normal white color for low color temperature (6500K) which is quite nice but people are used to the blue tint of most (but not all) LCDs I suppose.
[Galaxy Note 4 General] usmaak:
I wouldn't care so much about yellow or blue or whatever, if it was uniform. It's the lack of uniformity that bothers me.
[Galaxy Note 4 General] wm2001wm2001:
Currently it's kinda mixed. When I use my phone without glasses at night, I need to place my phone closer to my eyes, causing uniformity issues due to viewing angle difference between middle of the screen and edge.
[Galaxy Note 4 General] gass88tp:
Is it normal???
[Galaxy Note 4 General] usmaak:
Define normal with these things. To me, it looks yellowish at the top and darker at the bottom. Mine is opposite that. Yours looks a lot like my wife's Note 4.

Anyway, every one that I've personally seen has had some sort of screen flaw like this. I'm not saying that they all have it, because my sample size is way too small. But all that I have had have it.
[Galaxy Note 4 General] gass88tp:
Can warranty fix this problem ?
[Galaxy Note 4 General] usmaak:
You can try. I've seen people get them replaced and I've seen people getting told that there isn't a problem. It's hit or miss.
[Galaxy Note 4 General] istrikerx:
Mine is exactly the same as that.

This has been a common problem since way back in the S2 days.

The only models since that I've seen without these issues are the Note 2 and S4. Note 3 had horrible pink/yellow tint issues.

To me, it's a pink tint though. It will likely look more yellow due to the auto display thing.
[Galaxy Note 4 General] Zaino:
I went on Samsung Mobile Canada and sent them a message, posted on the wall and commented on a video.

All I've got in return was "we are sorry, call customer service". The rest of the messages, they ignored.

Calling customer service, back to the original 2 options, go to the service center or ship it in. Both ways, I either have to take time off work, or stay without a phone for a week.

Horrible customer service.

And at Rogers, they refuse to exchange because they say it's not an issue. Pretty much calling me crazy.
[Galaxy Note 4 General] usmaak:
S3 had all sorts of issues as well. My wife's S3 was very pink on the bottom 3rd of the screen. She put up with it for over two years. I exchanged my S3 twice. First time was for a huge gap on the bottom of the screen. Second time was for a pink tint at the bottom of the screen. The third one I got had the exact same gap as the first one. So I put a case on it and kept it.

When I was in the Best Buy where I bought my Note 4, I saw a Galaxy Alpha. It seemed to have a very nice, consistent, bright screen. The specs on it weren't as good as the Note, it didn't have some of the cool Note features, and it did not have a replaceable battery. The battery was a deal breaker for me.

I wonder if Nexus 6 will have a better screen. It's AMOLED as well. Of course that one doesn't have a user replaceable battery or Note features either, so not interested.
[Galaxy Note 4 General] gass88tp:
But, is it possible fix by software? I know that s4 was fix same problem by software... really?
[Galaxy Note 4 General] evoxsin:
On my sg3 i had hot spots everywhere very noticeable.

With the note4 im very happy to say that i see no inperfections with the screen....other than no glass cover fitting corectly.

Theres no pink yellow or blue spots. I usually have the brightness low. I was using dynamic screen mode and now switched over to basic and my eyes are adjusted to the low color saturation.
[Galaxy Note 4 General] ciscostud:
Samsung can't fix OCD
[Galaxy Note 4 General] gass88tp:
Why?
[Galaxy Note 4 General] AVF Jay:
Unfortunately "perfection" doesn't exist.

I have an oled tv and that suffers from screen uniformity issues on dark greys and that costs me a lot more than any phone.

The fact that some of you have mentioned that you've been noticing these issues and exchanging devices with amoled screens in them since the Galaxy s2 should tell you by now that uniformity issues and tint on viewing angles is a limitation of the technology and one of the flaws you have to accept, in the same way that lcd technology has flaws such as backlight bleed.

Now I know through experience that the severity does vary from unit to unit, in the same way that backlight bleeding varies from unit to unit with lcd displays. So by all means exchange it for another one if you have an extremely bad one but just accept that "perfect" uniformity will not happen.

Pioneer kuros that were basically held as a reference display suffered issues with uniformity due to dse, and Panasonic plasmas too had various uniformity issues.

Even professional grade Sony oled monitors which cost more than a typical car have "issues" in dark shades of grey.

I think people need to have a bit of perspective, just try and tolerate it, afterall for many of you it's only until the next phone comes out anyway.

Lastly to clarify I'm not suggesting that people keep a unit with severe issues, I wouldn't myself. But constantly exchanging devices and realising that 5 or more have the same "issue" should tell you that it's "normal". No one is that unlucky to exchange 5 or more devices and have faulty ones.
[Galaxy Note 4 General] usmaak:
I agree with everything you've said. It's the people that say that they got a perfect screen that keep everyone exchanging.
[Galaxy Note 4 General] AVF Jay:
I know what you mean.

I'll give another example that's similar.

Fan noise on say a games console. Someone will say their console is noisy, someone else will post and say theirs is silent. This will cause people to exchange their console in the hope of finding that "silent" console.

They go through 5 exchanges and each and every one of the consoles is what they consider "loud", but yet they see a few people saying theirs is silent.

Now is the person that exchanged several really "unlucky"? No, he just has a different tolerance level.

There are too many variables, a persons hearing, distance from console, ambient background noise, room acoustics etc.

Now to put that in relation to the screens, different people have different eyesight, different tolerance levels etc.

I often spot "flaws" that my girlfriend swears she can't see, even though they are clear as day to me. I'm very anal and ocd and tiny things bug me, to the point that I focus solely on the fault and end up not enjoying it and having to exchange and ultimately refund it.

What happens is rather than watch the screen, I end up "watching the screen for faults".

I also wouldn't recommend people doing unnatural scenarios to find faults. If you don't for example stare at a dark grey screen in a pitch black room in normal use, then why would you do it to look for a "fault". A fault is something that comes up in normal use, and again if you look hard enough you can find a fault in anything.

I can tolerate the faults in oled screens more than lcd as backlight bleed and grey blacks annoy me.
[Galaxy Note 4 General] usmaak:
Another example is anything Apple. I was one of the early adopters of the iPad 3. I went through a sick number of them, trying to get the perfect screen, because so many claimed that they got a perfect screen on the first try. In the end, I really wanted one, so I ended up "settling" for something that came close to perfection. Still a little dim and yellow on one side, but so much better than any of the other ones. I was going to keep going, but decided that I'd had enough of the return roller coaster that I was on. Also, a few people posted images of their so called perfect screens, and I could easily pick out the issues that they didn't see. Had the same problem with my Macbook. Three to get a screen that is almost perfect.

In all of the electronics with screens that I've gotten, I have yet to see what I consider to be a perfect screen. My Nexus 7 is pretty close, but there's some excessive light bleed at the top. Went through three of those. My Surface 2 is darker on the left side. Went through two of those. I have an LCD TV with a green stuck pixel at the bottom of the screen. That drove me nuts and I almost exchanged it. But after a week, I forgot all about it. I just thought about it now, for the first time in years.

I'm very picky. My wife is anti-picky. She doesn't see anything that I see. And on those rare occasions where she does, she doesn't care. She lived for two years with an S3 that was very pinkish purple at the bottom of the screen. The only way for someone like me to stay sane with electronics is to accept going in that I am not going to have anything perfect. This lets me lower my expectations. The only time that I'll return something now is if it has a screen with a very obvious and distracting defect, or if it's a physical defect.
[Galaxy Note 4 General] dannysmith43:
All good points. I'm only picky with mine while it's new. in a months time when the novelty wears off I won't notice a thing!
[Galaxy Note 4 General] AVF Jay:
I think that sums it up.

Every single screen has a flaw, it just comes down to what you can tolerate more. I remember the Galaxy nexus having really bad uniformity issues at low brightness, I exchanged several before getting one that I could live with.

It certainly wasn't perfect but was good enough for me to tolerate. And I think that's what people need to do with the note 4, find one they can tolerate. As if they set out looking for perfection they'll be disappointed and could end up with one that's worse than the one they had to begin with.

That's what normally stops me carrying on playing the panel lottery when I get a screen with minimal flaws, my ocd wants a perfect one, but then I think about how the next replacement could be much worse.

And eventually you soon forget about the flaws and just enjoy the device. After all what are the other options? If you go with a phone with lcd you can still have uniformity issues with whites being yellow etc, plus you can get screens with awful backlight bleed.

Oled even with its issues is better than lcd in my opinion.
[Galaxy Note 4 General] naimmkassim:
Perfection do exist out there, u just need to have some faith on it!! I also was going to giveup when its happen to me. Started from my note 3, but for note 3 i did not do anything cause i buy it from out side of my country, so there's go my warranty. To change a new screen here is quite expensive. Just like buying a new phone. After that i got note 4. Learn from a lesson, i buy my note 4 from trusted seller, direct from sammy. Again screen issue and i claim for warranty, first time claim still issue. I settle it on 2nd claim ?
