Screen Adjuster - Galaxy Note GT-N7000 General

Guyz I bought a galaxy note last week...just out of the box i saw a yellowish tint all over the display basicaly from the bottom left.....
so i got an app screen adjuster
i installed then adjusted the blue at +5 and now 90% of the yellowish tint is gone..
soo i have to ask is it safe to use this app????
heres the link to the app Here!

Sure its safe to use but if your note is flawed from the factory then take it back ??

I use it to lower the contract to -40 as it fixes some of the black rendering issues. I also set the overall brightness down to 75% as it is just set too bright (I turn it off when outside).
I have never fiddled with the colour as my colour renders perfectly. I agree that if it is not rendering correctly, send it back for a replacement. It will likely only get worse.

interesting how it helps you to solve some black rendering issues, but not at all for me.

Yeah its awesome but lags my ICS ROM down

its awesome app ... removes black blocks completely on videos .... is it factory issue with my note .. as i think it should work correctly be default .... isnt it ? ....

For sure is a very good and safe app but better now that is brand new it s better to take it back....

I have observed the similar thing.
I have now bought 4 Notes for myself and my family members (Yeah I know, 4 people in family with Note ). My personal one manufactured in October and those bought recently (3 of them, all made in January 2012) have different colour reproduction.
The new ones have slightly warmer colours when you look dead on (with slight shift to blue when you look at it from bottom at extreme angles which is to be expected).
But straight on, the new Note has colour reproduction similar to my Galaxy Nexus. ITs slightly warm. Its definitely not the colour calibration as it remains same regardless the ROM I use. Its definitely not like traditional SAMOLED blueish display like my old Note or SGS2 which I had before that.
All 3 which are manufactured in Jan 2012 have same colours. All 3 bought from different stores few days apart. But I dont think its bad thing. It actually little warmer like Nexus and is more closer to real life colours. I know that many people prefer artificial looking, eye popping SAMOLED colours, but I am definitely not complaining.

My Note has Black Color Blocking in videos ... so its faulty ? should i send it back in warranty ?

Black colour blocking is universal as far as I know. All of the Notes I have seen have it with hardware accelerated video playback. Using software decoding using players like MX video player or MoboPlayer or BSPlayer solves the issue for now and there is already work under way to fix this issue. I dont think you need to return your phone for this as new one will most likely have same issue.
What I mentioned was regarding general colour reproduction of the screen. The new Notes have slightly warmer colours everywhere. Be it in home screen, browser, gallery or video.

No, it's not faulty. Color banding or black blocks are just artifacts introduced by developers or the video encoding process for the most part - the issue is generally not apparent on TFT display types since the LCD layer isn't able to block 100% of the light to show you a true 'black' pixel.
Good dithering can hide the problem somewhat, but on OLED displays it's more difficult since they are far better with contrast.
You could look at it one of two ways...
You have a superior display technology that the world just needs to catch up with.
Or you have a worse screen because it doesn't hide what other display types are incapable of rendering.
Take your pick : )

Thats a relief ... i was also thinking the same thing as , other colors looks quite nice on my note ... only issue is the blocky blacks which on less resolution videos are more visible .... however i was able to solve the issue using screen adjuster app by setting contrast to 55% ... at that it displays no blocky blacks at all ... just the screen gets an overlay of grey for pure blacks..... i can live with it ...

Is my Screen defective Checklist

Yes I did just receive my Galaxy note.
Let's collect a step by step check list of all problems on defective screens.
I know that many of these artifacts are very subtle, and hard to detect unless you know what you are looking for, and is especially hard when you do not have something to compare to.
I hope you can prove a check list for all new users can check..
#1. Does the screen look good when you turn it on and look at it?
Yes: your screen is not defective.
No: your screen may be defective.
Really the only common "defects" that have been discussed here are a thread or two started by someone extra anal that happened to notice a common, but very slight artifact most likely related to the manufacturing process. When viewing a solid black background with brightness on high while in a pitch black room with your eyesight adjusted to the darkness, you can notice blotchy darker areas in the black. Every amoled I've had has had this "defect."
Some people also complain about the default color temperature and complain that it's more of a greenish tint. Every amoled phone I've had so far has had those same complainers, also.
If it looks good when you turn it on and use it, there's absolutely no reason to take a microscope to it looking high and low for defects. If you think yours is too greenish, return it and try another. Color temperatures and tints do differ from panel to panel. I had 3 nexus ones and each looked slightly different.

I doubt very much if you have seen the individuals screen so what you say is based on guesswork. I have been using amoled screens for nearly 2 years and have never seen anything like this. A movie hired from the market was actually unwatchable on my note. I could not even make out what was on the screen at times. Even video and pictures taken by the onboard camera are very poor quality when viewed on the note. There is also an issue with banding and auto brightness changing randomly. Yours may be fine, mine was not.

I actually noticed these black blotches in a completely black room with a pure black screen YEARS ago on my Zune HD. I was freaked out then as I thought I had a bum one. After awhile I found every one had this issue. Since I don't stare at screens with nothing on them in the dark I didn't worry.
I wouldn't get too freaked out by the black splotches as long as it is decent and you don't have any bad pixels (bad pixels are a dealbreaker to me).

Screen disappointment?? Anyone else?

Hi guys!
First off I wanna say I love my Note!! I have the Korea version as well.
Anyway, I still have my Galaxy S I which I ended the contract to get a Note.
I have to say as far as the "blacks" are concerned, the Galaxy S I wins hands down and also the text/color is sharper and even brighter than the Note.
I tried to take side by side photos but this was the best I could do to show the difference. Both phones are at max. brightness

http://imageshack.us/photo/my-images/31/img0006pq.jpg/
The pics do not do justice. In person there is a real difference. Even the capacitive lights on the bottom are brighter and whiter.
Not a big deal though when my Gaalaxy S isnt being compared to the Note. Just bothers me a bit personally
Thanks!!
Its becoz of the resolution . Galaxy Has 480 x 800 and in Note 1280 x 800, their is a lot of difference in these too models. anyway Supercurio is working on color issues on Note. lets Hope for better result.

After installing Screen Adjuster free from the market ..I just upped the red a fraction [+3] to get rid of the slightest green tinge to my screen.
Then installed Voodoo Screen from the Market and set it to Native Mode... this has fixed 90% of the banding issue on my Note.
Now the screen is beautiful and can hardly fault it.

Coming from a galaxy s with a perfect screen i have to agree that the black levels on the note is not as good and yes picture quality on the first generation screen is better even if its just plain pentile and non hd resolution.
People who started with the galaxy note are easily blown away but those who started with the first gen need more to be pleased. I also started a thread about this before and got the same results on the black levels.. im hoping that hd samoled plus can redeem the samoled family.
I think it is an amazing screen!!! I love it, about it being less bright, god I think the note is too bright. I never have it on full brightness unless its really bright sunshine, and in the dark I wish it would go darker, but it won't.
And the black levels!!!(I'm sick of hearing about this in the this forum) some people are so anal about this, I mean I can only just about tell that the screen is on, on a full black screen when I'm in a pitch black room, which I did to test the blacks. So 99% of the time you can't tell, and even in a pitch black room as soon as theres a pixel of light on the screen your eyes adjust and the blacks look black again. Secondly how many of you that are bothered about this, actually sit in the cinema or watch tv or when on the computer, say oh my good the blacks aren't quiet black. I can pretty much guarantee that all the screens in your life aren't LED so why bother so much about it on your phone?
I also love the screen. No disappointment at all!
Would you rather have 480x800!?
This is brand new technology! It pushes the limits of what can be done at consumer price.
And people are complaining!? WTF!
edit: I owned a SGS1, but I like the Note's screen way more. Much sharper.
Although I must say I'm not experiencing the issues I read about on the forum.

Are you joking???
I worked a few years in an industrial R&D department and designed new products, but we NEVER would have dared to release a product with such massive quality fluctuations (problems) onto a mass market! Especially when the screen is THE major unique selling argument!
Fine that YOUR screen is fine for YOU, but sorry, your arguments are pure ignorance! You do NOT have this issues, fine, then why judge about their seriousness??

Jeez, dont buy a samsung nexus then because that thing is a mess. Signal fluctuates so badly that its kinda funny. Fake screen size (the android buttons are actually on the bottom of the screen, reducing the screen size to the razr. The sound is a joke, the battery useless. Match that with no sd card slot no hdmi and the headphone jack at the bottom of the phone and youve got a 600$ flop.
I bought it for my 12 year old and even he doesnt want it. He wants me to bring it back and get a razr....
BTW, i have a bad s pen and the trademark samsung pink hue in the middle of my camera but asude from that, i love my note. When i saw it in youtube early 2011 i knew it would become my daily phone web surfer.
I wish for the same phone with S amoled PLUS, volume and sleep buttons not across from each ither, no pink in camera, mute button (like iphone) and the sane type of notification light as on the samsung nexus, micro hdmi out and quad core
try the free wallpaper called "no wallpaper" by simplicity apps. The blacks that you see with that wallpaper are amazing and it is free. i often use my phone at night when my child is sleeping, so lights are off and dark and see pitch black screen.
have 2 htc desires at home with amoled screens and the note screen is way better than that. have seen SGS and SGS2 screens and the note is definetely much better than that.
also try the wallpaper (free and paid versions) of KF Flames or KF Flames Donation by kittehface software. the blacks on that are also awesome with equally awesome flame effects. prefer the stock setting than variations possible with paid version but bought paid version just to support developer as liked free version.
the screen on even the sgs2 is no comparison to the one on the note. is your phone stock version or is having different roms affecting the display?
ICS should sort out most issues as its 32bit colour .... (or it could be 24 bit not 100 percent) ,,,
no wallpaper works a treat ... also lowering red to 3
still some apps which are lower density look like they have lines on .. but if you take screen shot they are still there when looking on pc so its the app not the phone
this phone rocks ... never ever going back to the half eaten apple ....

Where in my post am I "judging" about "their" seriousness?
If you find the screen their "major unique selling argument", why did you buy it before doing research on the screen?
If you are so worked up about the screen, why don't you get a replacement or trade it for a different phone?
Why do you point your frustration at someone who bought a phone he likes?
Because you bought a phone that you do not like?
Really, if you are so pissed off that you have to enter a forum discussion this angry. You should return the phone.
If you worked in a research and design department you must be a smart guy. You know getting angry won't get us anywhere.

The blacks on my old S2 is way deeper than the one in the Note.
Disappointing for sure.
But i'll take sharper screen over deeper blacks any day.
Well I was the proud owner of two notes this week, first one had a screen which used to tint between pink and green, so I got Amazon to send a replacement, which came today.
Alas this one isn't rendering the blacks properly and makes Black & White photos and videos look awful, pity as I'm a photographer and wanted to show client photos on the note (First note rendered Blacks great, just the white balance kept going off every odd second or so).
So two notes being returned, not taking the risk again.

I'm not sure how the black levels are perceivably different from one OLED screen to another, whether it's AMOLED, SAMOLED, SAMOLED Plus, or HD SAMOLED.
I mean, think about it...
All OLED displays are actively lit, which means that each pixel is its own source of light as opposed to being, essentially, active colour filters for a backlight, like on an LCD.
Let's go ahead an use 24-bit colour for the following example:
Basically, each pixel is able to register 256 levels of intensity per colour, which is represented by 8 bits per colour. And since you have three colours (Red, Green, and Blue), that's 8 bits times 3, hence 24-bit.
In the case of an LCD, where each pixel is essentially a filter, blocking or allowing backlight through, a bit value of 0 for any particular colour would mean fully blocking light, and a bit value of 255 would mean fully allowing as much light through as possible.
However, since the backlight in an LCD is always on, regardless of the image, the front panel isn't always able to completely block all the light, even on a completely black image. That's why you're still able to see a little bit of bleed-through, even on the best LCD's.
With any kind of OLED display technology, this is not the case however. On an OLED display, each pixel is essentially a microscopic cluster of light emitting diodes, and since each pixel produces its own light, there is no backlight whatsoever. Thus, on an OLED display, a 255 bit value for a given colour means full intensity, and a bit value of 0 simply means "off."
Q.E.D. on any kind of OLED display, true black is truly black in the same sense that when a light bulb is turned off, it's completely off.
So, if you're perceiving a difference in the black levels between respective OLED devices, it could be simply that you're not viewing a truly black image. The image might contain pixel bit values close to 0, but not actually 0.

[Q] Yellow Tint & Brightness issues (again!) - Why??

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
I had the same issue, then flashed custom ROM and it was fixed. Go figure :silly:

Screen coloring green/blue/etc. at slight angle

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.

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).

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.

Great Phone, same old AMOLED problems.

I'm about done with AMOLED panels and I'm about done with the S7 because of it. Ever since phones went quad HD (Turbo, S6, Nexus 6, Turbo 2, Note 5, 6P, S7, etc), this has been a problem, and unfortunately it still seems to exist on the S7. This is my second one - the first one had it in a different area on the screen and it was even worse. It's the pink fade on light or white backgrounds. Once you see it you can't unsee it. I'm sure some will come in here and say they can't see it. I noticed it looks all white at the right angle so if you're not seeing it, you might move your screen a bit. Also, the first image (the horizontal one) shows it the most b/c it has the subtle camera lines which make the fade even more obvious. Not sure if there's a point to this except to vent a bit and, I guess, see if anybody else has had this issue on theirs. Given that the screen is supposed to be one of the main selling points of this device, it's hard to keep it when I see the fade every time a lighter background comes up...
Honestly, I don't really see one benefit to having an AMOLED panel any more - even the highest quality ones eventually deal with burn-in, the battery life is not any better, and they have inconsistencies which are apparently just par for the course. #frustrated
Hmm my S7 doesn't have this effect at all angles and I don't think this is something with AMOLED displays. I think it's the new gorilla glass and the refractive properties of it. At some angles it looks blue and others pink but looking straight at the phone I don't see any weird hue just perfect white. The colours on the S7 display are the best for an AMOLED screen so far and I can say that since I work in a paint store and colour matching is my life.

I know what you're referring to with the refractive properties on Gorilla Glass 4 and this definitely isn't that. I'm even able to see the inconsistencies on darker backgrounds as well. I've uploaded two more photos, attached to this post. That's a solid dark grayish/blue background.
Pick your poison. With AMOLED you're going to get higher brightness, contrast and color saturation, but it will shift colors on whites with various viewing angles. With LCD you'll get colors that are less saturated but more stable and no true blacks (thus worse contrast), and it's brightness, contrast and saturation will all degrade at higher viewing angles.

AMOLED screens are also thinner and consume less energy.

I know, and I guess I shouldn't be surprised. Though I don't think we're talking about just color shifting at various viewing angles. This fade (and prior fades) appears to be "burned" in to the screen itself, and while differing angles help a bit, it doesn't change the problem.

And it looks even worse when you compare it with your friend's perfectly white iPhone screen..
But the better sunlight legibility and perfect blacks appear as a fair trade in for me..

I don't know - obviously that's subjective, but even my iPhone 5S is still just as readable in sunlight, and having inconsistencies in the screen appearance on a $700 device, to me anyway, is hard to justify for the sake of pure blacks.
Many will disagree, but this is why I still think the iPhone 6 Plus has the best display. I own an S7 Edge and while my screen colors are even with no pink tint, the entire display does have a bit of a green tint to the whites and I can occasionally make out horizontal lines where the brightness isn't perfectly even on grays and whites, especially noticeable when scrolling. My S7 Edge is about as good as I've seen any QHD AMOLED display, certainly much better than any of the S6s I owned, but it's still not perfect, and I would still prefer the display from the iPhone 6 Plus. To me, good, even, uniform whites are more important than perfect blacks because most of the things I do on my phone involve white backgrounds (web pages especially).

One thing I would like to point out that you are completely missing is the contrast, not only black-white but the colour contrast! This is another area where S7 screen is clearly superior than 6s plus or any other mobile lcd. You can verify that by viewing a colorful wallpaper side by side on both the screens. Another thing is colour accuracy and colour gamut in which S7 screen again comes on top.
Both types of screens obviously have their pros and cons but SAMOLED screens arguably do have more pros over lcds than cons imho!

Agree 100%. And at least the blacks on LCD's are consistent. They might not be "pure", but they are consistent unlike the whites in AMOLED.

You call it superior, I call it over-saturated (), even still on the latest and greatest. Don't get me wrong, they look nice and my eyes get used to it after awhile, but no matter what I do the S7's screen (and S6's, and Turbo's, etc.) feels "cartoonish" to me when navigating through the UI. Every time I go back to LCD from AMOLED my eyes feel a small sense of relief - almost like the contrast was too much. I know that's not the norm, so fortunately we have choices. But I love everything about the S7 except, ironically, its screen because of these inconsistencies. I simply shouldn't be seeing a fade from white to pinkish grey on an all-white background on a 2016 flagship.
Lol.. it would be a shame then if apple goes with amoled displays in future ?! Anyway you seem very clear about your preference of the display type so I'm not going to contest that, but I would say that lcd displays are not free from fault like amoleds and they do have issues like backlight bleeding, abnormal tints, non-uniformity issues, dead / stuck pixels etc.
BTW, I'm not here to preach about amoled or lcds, it's only my own experience with both the display types in the past. My experiences might vary from yours but I've always had them better with samoled screens than lcds.
I just bought a s7 flat 2 weeks ago and its my first AMOLED phone., i dont have any kind of color uniformity but i can see the strong blue tint in white when i look at the screen from an angle, and its really distracting me too much. I dont know if i go to warranty and they can fix it.

No, as that is the nature of the technology. When viewed at an angle, LCDs maintain color uniformity but lose saturation, brightness and contrast. AMOLEDs shift to blue green but maintain saturation, brightness and contrast. Refer to my post above (#4) and check out the picture.

I see it, and i aggree with you but, color shift is more disturbing then losing brightness. Its not affecting when using phone most times but whenever i use my phone with one hand and try to open notifications, blue tint is appearing and i really hate it. Actually iam in love with blacks of amoled screen, but this thing is driving me crazy. Maybe i am just too sensitive this color changes.
And btw, my father have a Galaxy A3, and it has exactly same blue tint on his phone too. I Think samsung should something to fix it for next Galaxy S. Its really annoying.

It has to do with the varying luminescence and longevity of the various colored pixels. AMOLEDs have been like that since the beginning and it won't be fixed by the next generation of devices. Once you get in the habit of keeping the phone perpendicular to your eyes, it's not so bothersome. Then you go back to an LCD and see that it looks so flat and dim and decide it's totally worth it.

Sorry, didn't mean to sound so dogmatic. I really don't dislike AMOLEDs, the imperfections just frustrate me on such a high end device. You're exactly right that LCD's can also have flaws, but I see them much less than I see them in AMOLED panels - which is just inherent to the two different types of technology and how well the OEMs implement them. I was able to exchange the one in the photos of this thread for a new one (two guys at the store agreed it was an issue) and while the new one isn't perfect, it's MUCH better to where it's not all I see now.

There is truth in this statement. Despite my overall preference for LCD, when I use AMOLED for a period of time and go back, it's a two-fold reaction... one reaction is slight relief on my eyes, but the other reaction is getting used to the "dullness" - though I find I get used to that much faster than I get used to the high contrast when going from LCD to AMOLED. I would imagine if I stuck to a phone for more than a few months and that phone was AMOLED, the change back to LCD would be even more difficult.
if you have polarized sunglasses then lcd display is a curse

Disappointed this is still an issue with AMOLED screens, this frustrated me to no end on my Galaxy S2 where the screen would shift yellow from one end to the other. Glad you posted this thread as it's not a widely addressed issue, guess I'm going with HTC 10.
I've never noticed this on any of my AMOLED displays. Nor have I noticed any burn in, and I'm not sure what you mean by "other inconsistencies," but if you mean sample to sample variation that affects LCD panels, too. And if you don't like the high contrast, that's adjustable in Display settings.
What I have noticed is vibrant color and ease of using in daylight that no LCD panel can match. Or even come close to. I guess I'm done with LCDs.
