My first Galaxy Note had dead pixels, burn-in effects (don't know what you call them but there are pictures in the link below). The second one I got as a replacement had much more burn-in effects than the first one. The third Galaxy Note had burn-in effects but not as much as the first two, but the gyroscope isn't working on third one, yes I've calibrated it like a thousand times. All of these phones had the burn-in effects out of the box, so it wasn't I who was overheating the phones screen or something like that...
There were also other minor problems (with all three phones) like bad audio quality, bad Bluetooth connectivity, minor lagging and small blocks appearing when watching videos (yes, even of high quality videos) which doesn't appear on any other phone I've had.
I've never had any of these problems with another phone. I've mainly used Sony Ericsson and Apple phones. Off topic, or maybe not.. I also bought an Samsung Galaxy S2 for my girlfriend and it too had burn-in effects and a burnt in status bar (nothing she really cared about, I take it as does most of the people who have it), so it's not just the Galaxy Note suffering from this issue.
Now I'm here, with my third fricking defective Galaxy Note, really pissed off at these issues. If one pays ca. 500+ euros for a quality phone made by the "best" phone company in the world one doesn't expect to have these issues.
I will try to solve this by contacting Samsung. But I would ask of other owners of the Galaxy Note to do the following test on their phones and post a result.
Download the app:
1. Dead Pixel Detect and Fix
2. Start with choosing the colors white and grey
3. Within the app, go to settings, set brightness to lowest.
4. Be in a dark room and look for these burn in effects I'm talking about (dark vertical and horizontal lines + smudges).
Take a picture of the screen with another camera, taking a picture with the phone itself won't show these issues as it's not software issue but a hardware issue.
These were my results with the first two phones I bought:

Thank you.
Looking at your pictures they do look very bad, I cant even tell if that is supposed to be a white or grey rendering on the screen but thats an obvious defect.
Did you get your note from a retail store?
I've also had several replacements with my S2 and I ended up getting a refund.
IMHO, part of the cause of this really low quality control is not by samsung but from other users who accept obvious defects to be normal or tolerable, sure its gonna be a PIA to have it exchanged upto more then a dozen times but since a great majority of them are just accepting it so samsung is giving us sup par quality control.
Can't remember if the colors were white or grey on the first picture, but they were definitely the same on both phones!
I bought the first two phones from amazon.de, I got my money back from amazon.de. And I got my third galaxy note yesterday from handyshop.de...

Might be. It seems like the people who are buying Samsung phones doesn't know what quality is, so they just keep the phones and praise the company and the model.

They know what quality is, they just accept the defects as normal. For me I find it hard to accept some of the screen defects when I never faced this issue with first 2 SAMOLED devices. I guess its the flawless screens I had with my first 2 devices placed me in such high expectations especially on the SAMOLED Plus.
I'll try to see if I can also have mine replaced, the only issue I have is the faint horizontal lines, can be seen even when browsing. No effort needed to see it.

One does not necessarily need to do the test I've put up to see these defects, I can see them whenever the background image is grey or white.

Sorry to read of your difficulties, but you do realize their are plenty of Sony and Apple owners with similar problems, right? You've just been lucky until now.
I have a SGS2 and My screen is perfect! Tried the app that is mentioned and all colors are perfect! Maybe there is a bad batch of Super AMOLED HD panels floating around. Don't know but I have never seen SAMOLED screen in such a bad shape! And I've seen a lot! Have somebody heard of Nexus Prime having this issues too?
Sorry, but may you take one picture and draw a circle around the defects? I'm honest: I don't see the banding/burn-in effects on your pictures, nor any dead pixels.
All I see is a poorly made photo, which isn't really sharp, sometimes shaken, and has a lot of grain, probably taken with a low cost camera at a too low brightness the camera isn't able to work with.
If I run the program on my HTC Desire (AMOLED) and on the Samsung Galaxy Note (Super AMOLED) I can't spot an failure. I see a minor burn-in in the notification area, which has nothing to do with quality control but rather it's a display technology limitation.
Else I can't spot any defects, no burn-ins, banding, ...
Just as I don't see this on your pictures, except a lot of grain caused by your camera.
One thing is obvious, that at the lowest brightness setting in a dark room, displaying a dark color, taken with a high exposure time, one can spot a difference in color reproduction between both models. But this is no failure at all, because the difference is minor and the frame conditions stupid. And you probably wouldn't be able to tell a difference without a direct comparison at such artificial frame conditions. And the question is, do other manufacturers allow such a low brightness? Do others have such an evenly lit display?
I really don't see any failure with your models.
So please, make a good photo, with a good DSLR, which is a necessity at such low lights, mounted on a tripod, and then draw a circle around the dead pixels, the banding and the burn-in.

Never heard of any screen problems with Apple and SE, (not saying it doesn't exist) but yes I might have been lucky until now. But what are the odds, 3 gnotes in a row (+ my gf's S2), more or less. It's like all my good luck has secretly been accumulating a lot of bad luck lol. Yeah but I can live with this third one, it's not as bad as the first two. But the problem is the gyroscope. It works randomly.
This is a major feature of recent Samsung Amoled actually. People have been complaining of screen problem for Galaxy SII, Nexus and Note.
They might not want to make the same mistake with their new 2560x1600 ICS tablet.
I've been interested in other phones that uses Sharp's ASV panel.

Strange that you compare OLED displays with LCD. No LCD on earth has a black as OLED, so if you compare OLED next to LCD at such sub-opimatl conditions you'll notice, that LCD won't even go as dark.
And never had any sort of backlight bleed? Just do a google search 'iPhone 4 backlight bleed' which are issues which are obvious.
I still can't see the issues on your pictures. I see artifacts and errors caused by the poor digital camera you used, just as buk_grudziadz nicely compared, thank you buk_grudziadz. But I don't see display failures and you don't seem to be able to show me them, else you would have done it already, or?

Well your whole comment seemed more like an insult than any help. How can't you see the issues on the screen? There is only one color on the whole screen, do you think it looks even? You and your friend are the first two people to complain about the photo quality, I'm not the best photographer and I don't know much about how to take good photos, but the problem is very visible. There are black lines, horizontal and vertical and dark smudges. I wish I knew how to take better pictures, even if I did know I don't have the phones since I returned them.
I have the third one left, but it's not that bad as the first two. If you want I can take a photo of it with a galaxy S2.
maybe your phones have the issues, I don't know and I can't tell it.
It's impossible to tell if the photos were taken with a smartphone camera, which adds that much noise that any slight color failures get overshadowed.
Just as with the pictures buk_grudziadz has taken. The display in the photo taken with the DSLR looks perfect, which it is. The same display taken with the Desire Z looks wrong. It has artifacts, color distortion (green and red) seems to have banding, and is grainy (noise), but it isn't. The photo is totally misleading, just as yours are.
So by looking at your pictures your display looks wrong, but not because of the display, but because of the poor camera quality. You can't do better photos with a smartphone camera, even with a point and shot camera it's difficult, you need a DSLR with a large CCD/CMOS sensor and good optics to take reasonable pictures at such a low light. If you don't have one, ask a friend. But the photos you posted are useless, sorry.
Just take a look at the two photos buk_grudziadz posted and tell me, does the display in the photo taken with the Desire Z look faulty or good?
I think your problem is that you are a screen nazi. No screen is perfect. I myself found a dead pixel with your app that i never noticed.
BTW to my knowledge AMOLED displays don't have backlight and the pixels themselves emit light right? So if I'm right, how is it possible to even burn the image of the statusbar when Samsung uses black theme? black means pixels off. How can an image be burned in the display that way?
@UpSpin
They did have those issues and I don't care if you think they "maybe" had those issues. Who the hell do you think you are coming here and being rude, questioning the validity of the issues I've had. I've been through hell with these phones complaining, sending them back, waiting for new ones and loosing money. You are not helping by complaining about the photos.
Do you really think someone would waste their free time on lying about some frickin issues on cellphones? The first person to answer this thread clearly could see them, and I wouldn't post those photos if they didn't look like EXACTLY what I could see with my own eyes. I posted those photos here a long time ago in another thread and nobody complained about the quality. They all saw the issues, many of them had the issues too.
I'm on my third galaxy note and it does have these issues, but luckily not as visible as the first two. When using the same camera I used before and the same settings on the new galaxy note, the problems are barely visible. It doesn't give the new phone some banding or artifacts.
Now these issues was mostly visible when using the lowest screen brightness with grey or white colors (picture yourself reading a book or browsing the internet). It was really annoying and a quality phone from the best phone company shouldn't have those issues.

Thank you for your comment, it really helped me. Seriously though, my problem is that I care about quality, clearly some people don't judging by your comment. If I pay 500+ euros for a phone with an amazing 5.3" AMOLED HD screen from the best phone company in the world, I don't expect to have problems out of the box. And if you did read my first post you would see that the third galaxy note I have has those issues but not as much as the first two and I am FINE with it. I was just pointing out that all of the gnotes I received had those issues, more or less and I wanted to know if other people had those too.
Has anyone noticed that the warm colors are only available when looking at the display head on?
Tilting just a few degrees does keep the image sharp, but the colors are much colder...
What im asking is - is this normal, or should i get another?
Well - i just spoke to supercurio, he says its to do with crappy glass treatment, not the panel itself.
Will go and see what else they have at the store tomorrow...
Only a slight change in color for me. Nothing that I would say is an "issue". But, of course, it depends on your personal perception...
What more annoys me is the banding (gradient) and the oversaturated, unnatural colors that I experienced with all AMOLED displays until now. I prefer LC displays...

Seems to be common in Samsung devices but not all exhibit such a bad viewing angle, my Galaxy S and S8500 didnt have any color temperature changes when tilted even at extreme angles while my Galaxy S2 had a slight shift to green, while my note's first screen didnt have any hint of temperature change but after the screen replacement I had a blue tint with really bad viewing angles.
I havent seen how bad it is on the Tab7.7 but im guessing its gonna be similar.
EDIT:
Found this show case video on the Galaxy Note about the viewing angles, their unit doesnt seem to exhibit any color changes.

Don't let me stop you, just letting you know that its common among samsung devices but not all of them exhibit the same issue, a friend dropped by after getting his tab 7.7 about 2hrs ago and there is no color change at an angle, so yours might be faulty.

Man I don't post too often but you've gotta relax a little bit, take a chill pill.
The other guy does have a point in saying that its common to all Samsung devices especially the Galaxy S line of devices. I've had a Galaxy S2 that had color temperature change when viewed from an angle and even my current nexus does it.
I got my galaxy tab 7.7 2 weeks ago and I'm very happy to say that it does not have any temperature color change even viewed at an extreme angle.
And this guy did an unboxing and also mentioned that he has no color changes when viewed from an angle as well

Also he did add to his post that he saw a friend Tab 7.7 and it didn't have the color change that you mentioned.

That you notice.
This would be the first OLED or any screen (LCD obviously is bad for this) that doesn't change a bit when viewed off axis then. I have seen the Note, the Infuse, and even Zune HD screens and they all shift a bit when viewed at an angle. I would be very suprised if this did't shift at all but I suppose it may be possible.

Look at the video posted above on the note, it does not have any color temperature change as far as I can tell. Before I had my screen replacement it was similar to that.
Just bought three more for the office, all with perfect screens. The first was a dud, store took it back after some cajoling.
Thanks for the help.
No colour change with mine. Best screen I've have ever looked at.
Sent from my GT-P6800 using xda premium
I also took mine back because it turned blue when i looked at it at a small angle. New one is not perfect either, still distorting way more than screen on my lcd 8.9 though.
I wonder how many people just dont realise that small color distorion is normal and never complain and how many actually haver crappy screens (since i assume they are pretty much the same manufacture date)?

I also wonder what you're doing with your tablets... When I'm using mine I'm holding in front of me, I don't tilt it at 78.5 degrees only to see that physics does its job with the glass filtering/separating colours at certain angles through reflections between the two glass surfaces.
You can't just have everything: a super-tough screen glass, brilliant colours, high resolution, crisp sharpness, 180 degrees viewing angles in every direction.... Be happy with the best screen in a tablet so far!

Actually you can. My very first 7500 was PERFECT. As was an excellent Incredible S i owned.
Ive now seen 4 of these and none had what i would call a good screen compared to the LCD in my first 7500. Changing up to 170 degrees on it only affects the brightness not the pixels visible color temperatures.
I know there are other threads that discuss this topic (somewhat) but I wanted to post this separately because what I'm asking is very specific.
I've had about 8 separate Nexus devices from Google Play in the UK and every one of them has had the same issue:
The display has had a noticeably yellow but admittedly slight (possibly slightly brighter) tint on the bottom and left edges, while the right edge has been dull/dark.
This is specific because there are other and numerous reports of a yellow "tint" across the whole screen. This is not the whole screen, this is very clearly just the bottom third and left edge of the screen.
Some think that this is a "glue" issue that will resolve itself. Some think it won't get better. Some think that it's an issue they can live with. Some can't stand the lack of uniformity.
Well I can't stand the lack of uniformity because in my opinion, on a 4.7 inch screen, I find it distracting to be reading text on a solid background or white and the "white" or background colour changes as I read right to left or top to bottom. I consider a decent amount of uniformity to be a minimum requirement for devices which will be used in the way most of us use our phones and tablets. Manufacturers, seemingly, don't care at all except in the most extreme of cases. It looks like they are churning out whatever they can get away with. In all other aspects, the N4's screen is fantastic.
There's nothing anyone here can really do to help directly but it leads me to a question I haven't been able to find the answer to anywhere by Googling or searching other forums:
What is the cause of this lack of uniformity on these LCD panels? It seems to be LCD specific. As mentioned, some think it's "glue" but then others say not and in my experience the tint issues haven't gotten any better in the time I've had the devices that have passed through my hands.
I don't think it's the LED backlighting but could it be something to do with that?
Does anyone know, from a technical point of view why LCD panels are so prone to this issue with the yellow tints across *part* of the display. It's a very widespread thing as it's been noted on most of the iPhone range and a lot of other handsets too. Is there something inherently difficult for panel manufacturers (in the N4's case, LG) to do to make the panel evenly toned and lit? Surely it can't be that hard at this stage in the development of LCD tech once the manufacturing process is "calibrated" at the factory and underway? I assume these handsets are assembled by robots, not by hand. Is that right? Why is it so widespread? Is it a cost issue? Would I have a better chance of a quality panel by buying a more expensive handset? (Although I've seen many HTC One X's with the same problem - I did see one which was almost literally "perfect" in uniformity and brightness). I'd really appreciate any feedback on this. I know that because it's the "norm", sadly, the common response is to now "accept" the panels and handsets that are out there. There doesn't even seem to be a "higher end" manufacturer where high quality uniformity is more likely - or is there?
Anyone with a good/strong knowledge of LCD tech or the manufacturing process out there that can explain this?
Thanks!
***UPDATE***
I've now attached an illustration to show what I mean. ***It's exaggerated a bit*** to show the effect but illustrates the problem clearly.
Have you tried using a custom kernel to tweak the colors of the screen? The Nexus 4 is known for it's washed out colors so using a custom kernel like Trinity or Franco kernel allows you to tweak the color of the screen to your desire. Of course you will need an application to tweak the colors.
LG is known for light bleeding and or panel uniformity issues, I had to swap 4 LG tvs before I decided to go with Panasonic , my LG ips monitor that im typing on right now for my pc has light bleeding in some areas which results in low contrast. I saw about 13 different optimus g devices before I got the nexus 4 and the screens are beautiful with good contrast, punchy colors and good black levels with no light bleeding or weird tints while my nexus 4 has slight light bleeding right where the signal bar is located. I love this phone and its seems to get the " perfect " one you maybe have to swap a few times and to me the price kind of fits the quality of the phone but then I almost have enough spare cash to buy another one lol can't complain about that.

Thanks for the reply. I've heard elsewhere that LG specifically seems to have poor quality panel uniformity. I think LG panels are used by Apple who have had many, many reports of panel yellow "tint" issues on both their iPhone and iMac range. It seems to affect screens big or small. Having said that, HTC had similar problems and their panels were manufactured by Sony. I would *love* to know what's causing this or what is the reason for the yellow "tint" issue on part of the screen.

I have done all of that and with some success with all of the handsets I've had but because the tint affects only part of the screen in a sort of gradient - the calibration cannot fix it.
I'd much prefer a screen that had a yellow "tint" evenly across the whole screen then of course I could calibrate accordingly.

yellow patches is from the glue used in the optical lamination process, yellow tint is from the display calibration which is often used to reduce banding and gives more saturated/warm look to colors
if your device is affected by by visible yellow patches the only cure is to re-calibrate the display to reduce the effect and don't get the device too hot as it may increase it

Sorry but this is not what my OP is about. I do not have a uniform tint and therefore it cannot be to do with "calibration" of some sort unless I am mistaken. Neither do I have "patches" or "spots". This is very specifically about a gradient yellow "tint" that only affects part of the screen and trying to find out the technical reason(s) for its prevalence in a wide range of LCD screens used in mobile phones and of course the Nexus 4 in particular. I've updated my original post to include an illustration of the effect I'm asking about. Thanks!
I am pretty sure its a hardware fault and i assumed you tried to return it otherwise there is nothing else you can do so i suggested calibration to reduce the effect

hi stevenhw8, can U give me name and link to download your custom ROM? thank you.
There seem to be quite a few Note 4's being sold globally that suffer from serious screen coloring (color shifting) when watched from close to a normal viewing angle. To get an idea of the scale of this problem this topic contains a Poll.
This defect is most easily noted on a bright white screen (www.google.com, "Dead Pixel Test" app). Even at a slight angle (=20"-30" from dead straight) the screen will show a clear blue, green or red colored haze. The screen on a properly built Note 4 stays (close to) white, even at a wide angle.
Please let us know if your Note 4 suffers from this phenomena beyond a trivial degree or if it doesn't.
Also be aware to check for this defect BEFORE you root your Note 4, as Samsung will object or even prohibit you to exchange your device for a better model.

Thanks for the link! Was just going to add it in the opening post, but this also seems adequate.

I don't think there is such a thing as a "normal" Note 4. Every AMOLED phone from Samsung varies from unit to unit. I remember finding exactly the same differences between two Galaxy S3s where one had a tint horizontally and the other had a tint when angled vertically. Interestingly the phones with the greatest colour shift are usually the ones that go brightest when looked straight on. Either Samsung is making these phones in multiple ways from multiple factory plants....or for whatever reason using different materials (such as polarising materials) in the top layers of the screen.
Although I didn't check the tint on a second Note 4 I tried, I did notice that mine was obviously brighter at all points on the brightness settngs bar!
Either way, while bad uniformity is definitely a defect....I think this off-axis viewing tint is not. If it was a defect, it would exist with Note 4 only and not all the Samsung phones I have seen to-date. BTW my Note 3 also tints when viewing at an angle but a bit less than the Note 4.

I never had this phenomena with my 5 previous Note or Galaxy S phones, nor on my Samsung Tab S 10.5's. I did have multitouch issues on my Note 3 and 2014 Note 10.1. Seeing the screen of the Note 4 is plenty bright I don't care too much for the "more brightness" bonus, if it were applicable here. I compared my unit to a random store unit and in direct comparison I much preferred the store model. The white screen already looked a bit 'off' on mine, and the store model did not have color shifting at all.

What are the chances of both my Note 3 and Note 4 having the same "fault" though? My Note 3 goes bluish off axis, my note 4 goes greenish. Both screens are still perfectly readable at any angle, and only colours that noticeably shift are white/grey. Orange still looks like orange, red still looks like red.

I think it depends on the amount of color shift. My Note 4 has a clear blue haze even when looking at it close to dead straight. I watched a snowboard movie/documentary and snow went definitely blue with only a shift of 20-30 degrees.
It's really good news to know that many devices don't have the blue tint when shifting! If mine has it I'll definitely send it to maintenance. I guess repairing is better as I can look at the device at their facility and not accept it if I don't like the results.

It is really hard to be sure we are all seeing or evaluating this the same way. For example, if I display a photo with many colours, I see no shift at any angle. White is the most obvious and you need "lots" of it like a www.google.com screen to see it. I would say I am fine for 20-30 degrees before it starts shifting. I think you may have been a bit unlucky in happening to choose a snowboard documentary rather than Iron Man 3 or something like that etc! Then you might not have noticed it
I voted "No" because the poll asks whether the screen color changes at a "SLIGHT" angle. While mine does not, at a larger angle the screen does show blue tinge that increases with the angle.
I have this too, its normal?
I have the same "issue" actually it was the first thing I realized when I turned on the phone for the first time. I haven't even realized it with my previous used galaxy S5
It's probably caused by some coating layer. Nothing we can do about it, doesn't distract me much in a phone anyway. The screen is lovely apart from that, the black level made me almost cry when I compared it to my LCD TV. I so want an OLED TV now. Shame they are so expensive.
Mine does this:

Is this a faulty display or is it just the way this display works?
There are several factors involved,
- Amount of Oleophobic Coating which distorts the actual colors discernible by the viewer
- The Digitizer
- The Corning Gorilla Glass
- And the amount of bonding used to keep the AMOLED display adhered to its bottom layer (Remember: Organic by Nature).

I get all the colors green a little blue and a little red it actually seems to me like a [email protected] rainbow I don't mind it much because it doesn't distract me much but I will pay more attention in the near future before buying a Samsung phone again...
No solution to this feature?

It is not repearable by software or external means. Well, maybe a heater could do something, but I am not gonna try.
I sold my Note 4 and now have the Note Edge, which luckily has much less issue with color shifting.
While looking directly mine is red at the middle of the screen. While rotating, the red tint is appearing at the top or bottom of the screen according the rotating direction. Also Bottom part of the screen is also less white than top.
Forgive my not reading the entire thread as it's late and time is an unusually precious commodity lately...
My screen does develop an extremely mild hint of a color shift at slight angles, but I don't notice it unless I look for it. However, at extreme angles (at which I never view the screen, like greater than 75 degrees away from dead-on perpendicular to the screen surface) I do see not only greenish/bluish (almost like a faded teal) but also a magentaish hue. I suspect in my case it's a result of the manufacturing and tempering processes of the glass. LCD panels exhibit something similar when viewed through polarized sunglass lenses, but this is not the same: LCD panels have a nearly random-blob appearance where on this Note 4 it appears in bands running along the vertical (when viewed in portrait orientation) axis of the screen. At worst, I can make it greenish on the left side and magentaish on the right by viewing at around 70-80 degrees off perpendicular, so admittedly I have to hold the phone in such an extreme position to see this that I don't consider it a defect per se.
HIH.
At the moment, I have both devices. Having used the S7 Edge since the release, yesterday I switched to the S7. In shifting back to the S7 Edge just now, I noticed the two device's displays are quite different.
The S7 clearly has more saturated colors and looks far brighter. The S7 Edge, in comparison, looks slightly more dull when side by side.
For reference, I tested both devices in the same conditions. That is to say the S7 and S7 Edge with automatic brightness disabled and pushed up to maximum manual brightness. Also I tested both in a darker room. For reference both were set to AMOLED Cinema.
Unfortunately even when the automatic brightness is turned back on, it's clear the S7 still looks more vibrant.
Can anyone explain what's going on here? Is it simply that the Edge looks like it has a lesser screen because of the larger size and thereby lower pixel density. Or is it something about the panels themselves and thus the S7 that I have now just happened to get a better panel than the Edge.
Any thoughts or answers would be appreciated.
Displaymate tested them and stated that they are practically identical in terms of performance: http://www.displaymate.com/Galaxy_S7_ShootOut_1.htm. Any chance you can test out against another Edge?

Actually no, unfortunately. Neither device has been released in Japan yet. Both of the ones I have are imported.
The thing is lot more complicated...
Each S7 Edge has different display quality! When you put 2 S7 Edge Side by Side and compare, you will see that the displays have different tint (mostly yellow), and more worse: a lot of the displays are not homogeneous. that means that one corner or side is brighter then the rest of the display.
i wrote a few threads regarding this, i also sent a message to displaymate (because they test "cherry-picked" devices, and do not mention this), see here: http://forum.xda-developers.com/note-4/general/note4-amoled-screen-quality-t2906365
basically i do think that the s7 screen is better, due to the Edge screen is P-AMOLED to be flexible! but the differences between otherwise identical devices are really huge!
i ordered my 5th device today, because all of them had flaws:
1st: display not good compared to second device
2nd: the device i use now. very good viewing angles and no tint, BUT: left side of display is darker then right side
3rd: display strong yellow tint
4th: display almost good, slight yellow tint. would take this, BUT: front cam takes blurry pictures compared to other devices...
5th: ordered today!
you may think i'm a hypocrite or have OCD, but it makes me mad that a 800EUR device has such flaws!!!
The s7 has more PPI due to smaller screen than edge

Or, you know, maybe you're looking for a flaw that's not there? It's a well known fact by now that a bend in a display, like the Edge, will have some shifts in brightness, tint and contrast, especially right in that bend! If this is something that annoys you, then I'd recommend you stick with flat panels from now on, because this won't be "fixed" for awhile. It's just the way it is.
Also, you do not have OCD.
"Obsessive-Compulsive Disorder (OCD) is a common, chronic and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that he or she feels the urge to repeat over and over."
If you turn the screen on and off 30 times before you can make a call, you have OCD. If you have to knock your door five times each time you come home, you have OCD. If you think the smartphone's screen is the wrong hue, that's not OCD, that's just being picky.

I think you're being a tad bit OCD. At the end of the day, the S7 might have a slightly better display than the S7E but the screen size and battery size make the S7E better for me personally. If you're looking for a slightly better looking display then maybe you'd be happier with the S7.

Thx for the medical and display-tech lecture, I'm a university lecturer (engineering and physics) myself!
1) Display quality: You did not read my post, or my linked thread regarding note4! The display of note4 was not curved, and had the same problems as all of samsungs amoled devices before: When you compare 10 devices side by side, you will see that each and every device has different screen tone, uniformity, ... About 2 out of 10 I would consider "good", all other have flaws such as a not uniform brightness distribution (one side of the screen is darker then the other side), or bad viewing angles.
this is NOT a problem which every device has, as I always found one device in the past which was "OK" after exchanging a few times.
same happened last week and today: last week i got a device with a really nice screen, but the front cam took blurry pictures compared to the other S7E devices I have in front of me. this can be easily reproduced, so the cam or lens has a problem the other devices do not have.
the device i got today has the best screen so far (good and even white distribution, good viewing angles), the front cam is ok (a bit less sharp pictures then my reference device, but WAY sharper as from the last weeks device), but there is a scuff on the top metal frame of the display, between the glass and the metal. this is no dust particle, it is a real scuff. :| i will test the rear-cam as well, if it is ok i will stay with this device, as the scuff is not nice, but a minor issue compared to the display faults of the other devices.
also, i showed the different displays of all my S7E devices to friends and colleagues (because they thought i'm crazy because of my exchanges), and all of them see the display faults as well. you need to have devices for comparison, then you will notice how bad some screens are compared to others!
so no need to go for an other device as the S7E, because there ARE good ones existing. but you have to be lucky to get one...
on the OCD: this was half ironic, because i know that OCD really is.

I did.... not read that Note 4 thread, and I did (clearly not) understand what you said (blame the beers I had), but alright, I do understand what you're saying now, and yeah, there is a slight difference in each panel, and some will get a slightly better panel than the other one. That happens with every screen out there, including LCDs, and viewing angles are also something that gets affected, but I have the impression that this is more of an issue with LCDs.
I would keep swapping it until I got a good panel, so keep doing what you're doing until you get tired or hit the jackpot. The screen is rated as the best smartphone screen ever, so I promise you it should look amazing. The issues you're experiencing is very common though, and must be somewhat expected when we are early adopters. These are typical issues that Samsung will weed out with time.
I saw a strange think on S7E: the 2 sides of the screen have grey shadow area if you looking at it in a dark room with low brightness of course...is that normal?
My is perfect :sly:

I saw other phones and talked to other S7E owners, and they see this grey halo too, when the brightness is low and the environment really dark. Do you think that it is a problem of my screen?
