As seen by the NoLED app over in the dev section, and in a few other places on the net, people are finding that when they display a black image on their amoled/samoled screens in a dark room there is still light emitted by the display. it is not truly black
I would like to know why!
One thing i hear is about image compression and signal noise causing the pixels to not display #000000 black and instead a variant of black/grey causing the pixel to become lit.
This problem is not an issue during the day, i can't tell the difference when my screen is displaying black or off. but what it does effect is battery life.
If the screen isn't powering down its pixels then it is not saving anywhere near as much power as it could do
Also
How happy are you with your display?
I knew about the pentile problem before buying, however i am not dissatisfied with the display at all. Infact if i did not read up about it i would not have realised there was anything different with the screen.
Text is clear and sharp, images are vibrant, and colours seem true with no issue of pink problems like the desire
looool, look at any lcd screen(tv whatsoever) and you don't have true black, because the backlight is on. Only the best LED LCD screens in TV world have FULL LED backlight that can dim the leds from parts of the screen that are fully black in the processed image.
take care
yup, if you take apart your LCD watch, phone, laptop or monitor
you'll see 2 layers, first layer the LCD/TFT/AMOLED/SAMOLED/etc whatever new technology screen you can think of name it here.
then the bottom layer is pretty much like a light bulb/white led/ccfl or whatever you want to call it to light up the first portion of the screen.
most devices you can control the 2 separate pieces separately via "screen" and "back light"
you'll noticed that usually on software options what specifically lets you control both indedpendly.
Eh.. Yes But the SGS hade OLED screen. So it should be able to turn pixels completly off. My guess is that each led has some very small current applied to it possibly to speed up response off screen.
But it come close to true blacks..
EDIT
OLED screen has NO backlight... Each pixel is an tiny led...

thanks for the heads up, that's good to know
i've yet to take apart a new SGS to figure out how the AMOLED displays works
You guys need educating on displays lol
oled screens have no backlight, thus no backlight bleed.
That means that this is a software issue, unless the screen not powering down completely is intentional
Software issue and nothing more.
Open up the calculator, drag down the numpad, hide the 2 stripes (status bar and numpad drag bar) in the top and bottom of the screen, and tell me if you see any lighting.
There's absolutely nothing.
there is still light emitted. cover up the top and bottom bar with your hands, go into a completely dark room then look into the center of the screen.
There is a uniform glow, just like when looking at a black image in the gallery or browser
It's actually more noticeable if you look AWAY. The peripheral area of your retina will be able to pick up a very feeble amount of light. Feeble, sure, but it's there nonetheless.
seriously, guys?

The problem is that the way it is supposed to work is that if you display black, the screen shouldn't use any energy at all but it is and people can see it and so is using precious battery charge.
The issue is... that apps like noled which were going to display a red dot on the screen to let people know if they had mail waiting or whatever wouldnt use much power at all because they were displaying mainly a black screen but it isnt actually black and still using light so still chews through the power..
hope that made sense.. but that is why people are interested in it..
Ok, I missed the battery part, sorry If so, it is indeed an annoyance...
I thought people were seriously complaining about image quality.
I have the Samsung wave and it uses the same screen technology and I can tell that it does not have true blacks pixels are still lit, I can easily tell that its on and totally off there is a very faint trace amount of light produced..
Since I first got this device and turned it on I have been impressed with the display. I am kind of partial to AMOLED diplays and am, thus, a bit biased. What surprised me was that it "appeared" sharper than the display on the Nexus One. Considering it is slightly larger and at the same resolution I just assumed that it wasn't using the PenTile arrangement - yet it appears that it does in fact use the same subpixel arrangement as the screen on the Nexus One. My point is... now I've forgotten my point. Basically that I am more than satisfied with this display.
As far as the black issue is concerned I have no idea. There must be some reason considering that was one of the supposed strengths of this technology (i.e. true blacks and lower power consumption).
El Mono
wait so why would you display an image if you want to save battery?
really
How many of you have measured how much power is being used up when the display is displaying a true black image(measured with multimeter, or other measuring device)
How many of you have made sure that the glow is not caused by a residual charge in the display?
How many of you know how much time it takes for the "glow" to leave an OLED panel when power is not being applied?
just some food for thought
The thing is, amoled screens were advertised as having true blacks and having the pixels off when displaying black. this is clearly not the case
It's not an issue with the technology. The screen doesn't have a back lighting panel, so i think it's more of a problem of what shade is default defined as "black" in the system, or something with any current running through the screen.
Well considering the screen doesn't turn off when displaying a 100% black bitmap image, its safe to say that the say that the pixels NEVER turn themselves off during use when displaying black
Could be the screen isn't calibrated properly, or they lied to us about the tech(wouldn't be the first time).
While its not "true black" it is defenently beyond what any backlit screentype can do regarding blacks.
Except perhaps for the retina display forged by god himself
But I agree that if Samsung states True black then it should be able to do that.

I have a favor to ask... can someone with a 6P verify that the sRGB mode exists in the developer settings?
I have a 6P on order but I am concerned that is has a Samsung screen. I find Samsung screen colors to be disturbingly inaccurate. At least up until the 6 which has color option modes to bring it more inline with industry standard colors.
Nobody has one yet. Trust me, you will know when someone does, there will be 1000 threads about it.
Also, I've never heard of sRGB mode in Android. I've been developing ROMS for 6 years. Can you be more specific?
Some ROMS allow you to tweak the color output slightly, but not all. That's generally not a hardware screen-dependent thing. I have a Note 4, S3, and GNex, and all screens appear to produce quite vivid colors. Green is green, red is red, and so on. Actually looks very accurate.
How are you coming to the conclusion that, for example, it can't display blue as blue? What are you calling "industry standards"? You have something to gauge that with?
This is from the AMA
Yep, confirmed: Nexus 6P has the latest generation panels from Samsung. One of things we deeply care for is the quality and accuracy of the display through which all of us connect with the stuff we care about. We created a very tight spec (white-point temperature, delta-E variance, color-space accuracy, etc) for the 6P WQHD AMOLED panel, so it was important that we use the most cutting edge panel technology available.

The sRGB mode is new to the Nexus 6p, and hopefully new to Marshmallow in general.
I find AMOLED screens, especially Samsung AMOLED screens to be highly inaccurate in reproducing color. The majority of the internet is designed to be viewed in sRGB color space. Samsung uses a wider gamut color space which causes images to be supersaturated and not true to how they were meant to be viewed. Most of the AMOLED screens I have seen also reproduce white poorly as well. Industry standard white point for digital screens is 7500k. This produces a nice slightly warm white tone. The stark whites that many people gravitate towards are usually slightly blue and not actually white.
Everyone has there opinion of what they like but I prefer industry standard to assure I am viewing things as they are intended to be viewed.
In my opinion srgb mode is TOO desaturated. The saturation is too high with it off and too low with it on. Shame, I was hoping for a middle ground.
The sRGB option is horrific to look at, God this device has terrible options for screen calibration.
Native its massively over saturated with very popy cilors ( ala Samsung )
sRGB looks like some one lent on the gamma and brightness sliders.
It's one extreem to the other no middle ground - his bless custom kernels with color control down the line
sRGB is better on the eyes at night in lower brightness

Nope, both sRGB (99% of computer content) and Rec. 709 (99% of HDTV content) use a 6504K white point. They also share the same color gamut.

Pray that kernel developers bring color control asap because this displey is very poorly calibrated at best. And that srgb mode simply makes you want to throw up when you see it in action.

Nvidia Shield Tablet has sRGB default, sRGB Automatic and Native profiles, so that is at least one other device with it and now the Nexus 6P has it, not sure about any other devices though.

Mistype on my part.. I meant 6500k. I could probably tolerate 7500k though as long as it is within sRGB space.
I know this thread is a little old, but I just ordered my 6P so I've been doing research. sRGB mode is one thing I was interested in since I've always found amoled screens to be oversaturated, but I've also always been able to tweak them on my phones (Samsung Notes) through the stock rom. The Note 4 has a very accurate color setting called "Basic" and my Note 3 had it as well but it was called something else ("Movie" I think). The Note 4 got great marks on accurate screen colors with that "Basic" mode though. I figured since the 6P uses lower binned Note 5 screens that it would hopefully have something similar, and was hoping the sRGB setting would be just that. It seems though that the sRGB mode is too undersaturated.
Would it be possible to integrate that screen setting from the Note 5 or 4 somehow in a custom rom or maybe an app? I've not looked into how accurate the settings are in the Note 5 since I had no interest in upgrading to that phone over my 4, but I'll look into it. Someone else feel free to chime in.
Hey guys,
I am thinking of buying one of this mobiles. They both seems very good, got 3GB of RAM, big display (i want some bigger phone), but.... I am wondering which one have better display and which one got better battery. This is probably the most important for me.
If someone have more experience and use some of this i would appreciate your thinking.
Thanks in advance.
Note 4
Luckily for you, I've owned both phones since the month each got released.
Note 4:
Pros- bigger battery ( I've noticed slightly longer battery life)
- outstanding screen
- Pen
- Removable battery
- dont need to turn off phone to remove micro sd
- Ir blaster
- plethora of cases/accessories
Cons:
- Phone sometimes feels cumbersome to use
- Touchwiz sucks
Xperia z5
Pros:
- Sexy as hell
- Waterproof
- Normal screen size
- Camera button
Cons:
- Back gets warm pretty quick
- Doesn't have any of the pros listed for note 4
------------------------------------
Get the note. Every time I use my note 4 for something I notice how much crisper the screen is, and I hate not having that on the Xperia. Samsung did a really good job packing a ton of features in the note 4 and the screen will keep it future-proof longer than the Xperia. I actually prefer the note 4 to note 5. ( buy the unlocked version and install note 5 rom on it, you'll get the note 4's removable back + new software)
I also owned both and I should say Z5 screen is way superior to note 4.at least mine.I still have note 4 and can answer questions if you have any.
PS:note is easier to root and flash CM if you care.I had to return my Z5 because of lack of root for locked BL.I'm back to my Z2 and N4 is collecting dust.lol.
RE
Man,
Thanks a lot for this brief.
I always think that Sony have better display, probably because I am a big fan of Sony. But now when I see that Note wins bots display and battery I will for sure go for Note 4.
Just one more thing, because i am not that kind good with android and software. When you installed new custom rom to Note 4 you had no bugs or something like that? I found on forums that it can be very bad doing this so i need your opinion?
Thanks in advance!
Lol, comparing an OLED display vs any LCD display and pretending that LCDS can be on par or better than OLED displays is so dillusional its actually funny!
I would still choose Z5 but for different reasons: 1 performance, note 4 has a weaker cpu and gpu, z5 camera is more sophisticated than note 4 camera except z5 camera has no OIS and lacks several manual functions, but me and many others can live with that, Z5 has real radio, Z5 has water proof support and z5 has dedicated camera button.
Re
So many different opinions.
@ TheWarKeeper
Can you please tell me your experience with battery. I need it for my job and i am using a lot of calls, email-s, social networks.... Can it last at least one day.

It's not black and white. LCDs can and tend to be able to display proper white (sometimes you need to tweak it via white balance settings but YOU can have it unlike OLEDs) while OLEDs tend to have difficulty with it and never truly achieves proper whites and you have to calibrate with time due to OLEDs organic nature. But in contrary OLEDs displays deep blacks due to switching of the organic pixel (LCDs cant switch of becouse the R G B channels are just filters on top of the backlight). White is more important though as that is what is used most in apps, themes and so on. And due to the OLED being organic the blue, red and green pixel component each have a life length and blue has less than the other 2 which means having bright/white things displayed on your OLED would shorten the blue components life length faster resulting in uneven colors on the screen, "burn-ins" and it just gets worse with time.
LCDs dont have this problem becouse the only thing you lose with time is the brightness due to the backlight getting worn and so you can compensate by increasing brightness intensity. And Sony TFT and IPS LCD for their Z1+ lineup comes with Triluminos which adds an extra component to help the pixels and extends the color range to 85% of Adobe RGB 1998 ICC color profile which is far more than a regular LCD can do giving rich and accurate colors that without problems rivals OLEDs while still being proper and true to life without typical OLED oversaturation. Triluminos also helps with the black but cant rival OLEDs 'pixel switching off' blacks.
Now latest OLEDs from Samsung does better than older but they still tend to oversaturate since they also can display beyond standard sRGB color scheme that is the standard but cant really accomodate to it like an LCD with Triluminos can due to its organic nature and how it works.
You want precision that holds for years and proper white you go with Z5 but if you want deep blacks, "popping" colors and less precision you go with OLED. OLEDs also have better response time but that would mostly only be of importance if you play games at fast framerates.
In my opinion, you should also consider the UI of Samsung and Sony because TouchWiz (Samsung UI) is notorious for lagging as months passed by and when multitasking, while Sony UI is always smooth and rarely lags. :good:
I had a Note 4 before getting a Z5P. Stock Samsung is garbage. You have to look into AOSP/CM for the Note 4 and it may not be 100% stable. The Note 4's camera is definitely though. Z5 camera is only good on paper but in real world situation Note 4 wins easily. Z5 has way too many pixels can't produce a good image unless the source is extremely well lit.

The problems with white balance for oled displays are long gone, those issues were only present in the first few oled screens ever produced because back then the organic material for red and green were degrading at a different level than the blue.
My Galaxy S6 has the purest white any LCD dreams of and also a much bigger color gamut, also it has a fraction of the pixel response time of any gaming tft lcd out there producing less ghosting and blurring when in motion, on top of the pure blacks as you acknowledged also.
As for the over saturation, the oversaturation comes by default to boast the contrast capabilities of the oled screens, normally found in test units, my galaxy s6 for example came out of the box with such a toned down saturation that nobody would even dare to call it an OLED, but anytime i want to enable eye popping colours i just change the color scheme from the display settings itself.
Theres no reason to vote for a LCD anymore, except if you are concered about buying a monitor/tv thats always ON and not bothered with image quality, then LCD is best as it doesnt suffer from burn in issues, or color degradation, but frankly thats just about it.
EDIT: i also forgot to mention that the best LCD screen ive ever come across in any phone was the Xperia Z1 Compact screen, perfect color reproduction at everything, which put Xperia Z2, Xperia Z3 (both normal and compact) and Xperia Z5(Again, both normal and compact) screens to shame.
So for me the Xperia Z5 screens are dissapointing and white balance by default is over the top, too much RED, to calibrate it properly youll loose other screen abilities.

The phone should last a day as long as you dont push it and dont enable brightness to maximum all the time.
If it doesnt well, you can always get a pocket charger as the competition of z5 will last only a slightly more time which is negligible.
I would choose the Xperia Z5 over the note 4 anyday though, its a great phone and it wont dissapoint any average user.
Xperia Z5 only dissapoints enthusiasts like myself but not because of its quality, quality is great, but because of DRM and locked features which makes no sense beying locked.
What are you guys talking about? Note 4 has one of the best screens on the market. Near perfect white balance (6562K) and 99% Adobe RGB. Just use Photo Mode. Adaptive Display mode is over saturated but optional.
http://www.displaymate.com/Galaxy_Note4_ShootOut_1.htm
Also color burn is an old issue from Galaxy Nexus devices and earlier. Samsung displays have burn-in protection.
Moving from Note 4 to Z5P was definitely a downgrade in color accuracy and white balance, but upgrade in pixels. I honestly thought I would care more, but I actually don't. I rather have no screen door effect in VR and higher resolution. Now if Samsung released a 4K AMOLED screen...

The highlighted part goes against your first comment. All 3 color channels degrade independantly of each other based on what is displayed and how colors are used. Blue is still used the most.

I have not tunned the Z5c LCD but it does actually for my unit use to much blue. Though my Z1 has near perfect white balance with minimal tweaks aswell as boosting impressive contrast, top notch color reproduction and good viewing angles. For being a TFT LCD with Triluminos it is quite close to IPS LCD regarding viewing angles except when brightness on displayed material goes above a certain threshold but immensly better than a regular TFT LCD. I have a JDI panel btw.
So for me the Xperia Z5 screens are dissapointing and white balance by default is over the top, too much RED, to calibrate it properly youll loose other screen abilities.

Strangely enough it either goes for to much red or blue. Maybe panels come with different "qualities" and/or different assembly fabrics and quality. As long as you dont have to 'mute' a color channel to much to get good whites it should be OK else you lose brightness and contrast.

The camera is really bad in real world situations. Despite what you read in reviews that only test extremely bright or extremely dark environments, taking photos at home or indoors is pointless. People's faces will look like they were smeared with peanut butter. http://imgur.com/0OhbSaq
It performs worse http://imgur.com/Pfd76nR than my Note 4 http://i.imgur.com/wOvr0kl.png in indoor lighting, which means the camera was a straight-up downgrade for me. I don't bother trying to take pictures unless they're daylight or I can use flash which, to make matters worse, is still extremely weak. This all seems like extremely crappy postprocessing smudging pixels together and there's no way to turn it off since there's no RAW support.

I own the Z5c and cant relate to what you are sayinh although it sure needs some white balance and algorithm tweaking. In your photo comparision it looks like the Z5 photo was taken with zoom and possibly older firmware vs just a crop from the Note 4. Without ISO and shutter speed info it's also quite pointless "comparision". Exif would show it zoom was used and much more. I can say though that not even with ISO 6400 in low light does my Z5c produce such bad image quality. Only with zoom.
And the test I linked to is properly done with information and different scenes with different lighting conditions unlinke the "tests" by random people on the interwebs posting photos without exif data nor information and croppings where you have no orignal fullsize photo as reference either. Who has more credibility, that test or your "test"? Anyway it's pretty much settled in stone that the Z5 is better.

I own the Z5c and cant relate to what you are sayinh although it sure needs some white balance and algorithm tweaking. In your photo comparision it looks like the Z5 photo was taken with zoom and possibly older firmware vs just a crop from the Note 4. Without ISO and shutter speed info it's also quite pointless "comparision". Exif would show it zoom was used and much more.

And you missed the point...
The point is, these are real world samples. The first shot was me at a wedding. Yeah, it's zoomed, but not the point. The point is the heavy smearing of pixels the post processor does, ruining the quality, just because to Sony all noise is bad.
The second was my Note 4 and Z5P both taking a picture at the exact same distance of something I have at home in dim lighting. The Z5 is straight up worst and if you can't see that, that's some serious " fanboyism" there. And yeah, my Z5P running 6.200, so no, it's not an "older firmware." You don't need EXIF data to see the point I'm making. In dim lighting, the Z5 severely underperforms. But you rather believe my sharing of these photos is part of some conspiracy to maliciously fake a comparison so the Note 4 is better go right ahead.

They still suffer from uneven colors and shades over the display.
The whites are though life dependant and Triluminos widens the color gamut to 85% of Adobe RGB 1998 ICC profile.
Interesting. So kind of cheating for tests/demoing regarding readability as you cant have both maximum readability and accurate colors.
The highlighted part goes against your first comment. All 3 color channels degrade independantly of each other based on what is displayed and how colors are used. Blue is still used the most.
I have not tunned the Z5c LCD but it does actually for my unit use to much blue. Though my Z1 has near perfect white balance with minimal tweaks aswell as boosting impressive contrast, top notch color reproduction and good viewing angles. For being a TFT LCD with Triluminos it is quite close to IPS LCD regarding viewing angles except when brightness on displayed material goes above a certain threshold but immensly better than a regular TFT LCD. I have a JDI panel btw.
Strangely enough it either goes for to much red or blue. Maybe panels come with different "qualities" and/or different assembly fabrics and quality. As long as you dont have to 'mute' a color channel to much to get good whites it should be OK else you lose brightness and contrast.

Ok well it makes me think that you didnt own a proper OLED phone, maybe you did own a bad one in the past and the screen was crap (defective).
First of all, OLED screens do not result in color saturation shift when degrading because the software inside their panel drivers automatically correct the color shifting, (my galaxy s2 still has top notch colors).
As for the cheating, i have no idea what you mean by that, you can saturate the colors or desaturate them at your will, i dont know what cheating is involved because there isnt any cheating at all xD
I have tuned my Xperia Z5 screen and i had to keep red to minimum and blue and green almost to max to get a proper white balance, doing so, resulted in severly desaturated colors and bad luminosity (as the panel software disallows maximum brightness values when colors are calibrated).
I never liked the Xperia Z1 screen, a small tilt resulted in horrid washed out colors, Xperia Z1 Compact is a completely different beast with the best IPS panel ive ever seen in any phone 1800:1 contrast ratio (native)!
As for that complaint in the note 4 forums, its obvious that the user of that phone suffers from the typical defective screens that samsung fails to stop at production, uneven color or tints of any kind on the screen is not a characteristic of an oled screen, its a characteristic of a defective unit, i have to change 2 galaxy s6 untill i got 1 with perfect colours, i had to change 1 galaxy s2 to get the good screen and the galaxy s4 i got it with perfect color reproduction from start.
Finally, LCD screens were always the worst type of screens in term of image quality and color fidelity, even at professional image editing level which means wasting thousands of dollars on a proper IPS LCD screen, professionals were never really satisfied with its color reproduction and instead choose to use old school CRT monitors (myself included).
The only reasons why LCDs are successfull is because of good marketing, they suck at color accuracy, they suck at pixel response time and they suck at image definition. (My OLD Sony CRT ran 75hertz at 2048x1536)
It was a joy to use in any type of situation, movies, playing games and image editing software.

You still lose luminosty and or/color representation quality when correcting the other channels to lowest common denominator uniformly. S2, S3 and played with S4 and S5. The former ones wher just horrible. You could almost spot the pentile matrix design and colors overly saturated. "Eye bleeders"! :laugh:

You mean you had to set green and blue close to 255? That sounds like your screen is way off. I might look into mine later and see how much it needs to be tweaked via the white balance setting.

Well then that was the AUO panel. They made an ugly one by having different panels. I got the good one, JDI and I can tilt it and have very close results to that of an IPS LCD as long as the displayed graphics aint overly bright (lots of white) where it then performs worse but then I am talking about extreme viewing angles. Btw OLED also looses quality when tilting at sides and has 'color switching' and black suffers (if pixels aint switched off).

Still better than having uneven colors and blotches. Nothing worse than having a display that looks like a CRT that has been abused with a magnet (not as bad though but still!).

Right.. 3 on a row, 5 on a row, most/all retail store display units.. Then going by what you say Samsung has horrible QA for their OLED displays and you are in for a ride in the lottery. Tons of people in the 95 page thread going through multiple units all with the pink/green blotches with varying severity. Pretty few getting a rplacement display that has none. All showing some color hues and some reporting it going worse by time. You even got a video showing differences in white point color to at same display color settings!
I even checked at local mobile phone store and S6, Note 5 units had color blotches on a white background. Some better some worse but still there.
Just Google it.

Lots of users getting this with hard evidence to prove it. #Pink#Gate
You guys looks like one work at Samsung and one at Sony ??
Hello.
The two s7-s, normal and edge, both the Exynos versions, have:
1. different max brightness
The Edge is a lot more darker. The are both set on Amoled cinema and manual brightness. What could case such a difference?
2. WB on Auto is different. (Separate problem)
The Edge produces an accurate WB of a winter scene, while the normal one has a blue tint.
Is there a logical explanation as to what the cause of these differences may be?
Greetings
Brightness ofcourse would be different. Same was the case with previous generation. It's due to the physics and difficulties involved in manufacturing the curved screen.
Regarding the camera I'm not sure. May be one phone has sony sensor and the other one has Samsung's own sensor.

edge amoled is not as good as regular one. regular uses glass amoled, edge plastic amoled to make it bendable. do not confuse this with outer display glass, this is in both cases corning gorilla glass!
in regard to the camera:
there are Sony and Samsung sensors used in production. luck of the draw (batch) which one you get.
Sony is considered slightly sharper and a tad more low light performance, Samsung has better white balance (Sony tends to yellow sometimes)!
In general:
I have to cycle through at least 5 devices each time I buy a Samsung phone, due to MASSIVE deviations in display quality between otherwise identical devices. This is due to amoled production method, only few displays have "good" white and no color tint or shift across the screen...
I've started a few threads about that in the past, if interested search for them!

Generally very pleased. But Basic mode on display still is very saturated . Also since when was warm a pink hue? Ive always led to believe warm is short wavelength that should exhibit a yellow hue which mine doesn't.

I would like to know the settings for best accuracy since I'd like to edit photos on this, I read the screen has an excellent accuracy but mine is pretty yellowish. Tried the basic mode but its absolutely lifeless and lacks contrast.
Hello. Home theater enthusiast here. Thought I would share my opinion as I have my own calibration tools (i1d3 with HCFR, Lightspace and DisplayCal, and eeColor boxes for 3D LUTs for 1080p and lower content (4K boxes are still too expensive IMO).
This is by far the best display I own. This thing is just as good as my LG E6 OLED... with a 3D LUT! I'd like to mention that the E6 and similar displays are deployed and used for critical grading of movies due to their accuracy and gamut coverage. Without a 3D LUT they're pretty crappy due to limited and buggy built-in calibration controls (you can only have part of the gamut accurate by sacrificing accuracy everywhere else. Skin tones, memory colors or a distributed error focusing on improving the 50-70% saturated colors, can only have one of these or none at all.
Sorry, getting off topic, back to the Note 8 display.
This is very important. DON'T USE ADAPTIVE MODE IF YOU WANT ACCURATE COLORS -OR- THE STANDARD D65 WHITE POINT COLOR TEMPERATURE.
Adaptive has a fairly aggressive boost to saturation. Also, the RGB slider controls are for controlling the SECOND saturation boost on top of what Adaptive has already boosted!
Adaptive/Cinema/Photo use a DCI-P3 in BT.2020 colorspace
Basic uses rec.709/sRGB colorspace.
All non-HDR content (movies, pictures, graphics) do not use this color space. The colors will not be converted properly (primaries and secondaries have an axis shift. Also, 50% saturation in sRGB/rec.709 (non-HDR movies) will be at a different location in the visible spectrum (i.e. not the same color). This is a notable difference if you can quickly do an A/B comparison.
Basic is the most accurate colorspace simply because it's rec.709/sRGB and that is what everything was made for. Use Cinema or Photo if you want/like the saturation boost that happens when viewing /rec.709/sRGB content with a DCI-P3 in bt.2020 colorspace.
HDR videos have embedded metadata (sort of like ID3 tags for music files) which will trigger the display to automatically change to the appropriate and totally separate color space that you can't choose in the display options. The reason for this is because HDR by spec needs each pixel of the screen to produce drastically higher luminance (nits). rec.709/sRGB generally reach up to around 300-400 nits at peak on a quality display while HDR has a defined peak of 10,000 nits by spec. No current display can reach this yet, most are around 2-5000 nits (OLEDs are in the 700-1800 range. See AVSForum for discussions about OLED vs LCD/Quantum dot/Projector HDR nit levels).
This prevents users from using HDR levels of luminance for extended periods of time. More nits needs more voltage, more volts means not only faster battery drainage, but also more heat is generated and shortens the life of each OLED subpixel as the organic compound ages (more voltage quickens aging).
Image BURN IN is caused when some OLED subpixels have aged faster than others near it. This IS permanent.
Image RETENTION is NOT permanent yet looks just like image burn in. This is from voltage that has built up and can no longer be contained in the components controlling each pixel. Simply discharge them by turning the screen OFF (As in power off. I think Always On Display keeps them primed and ready for use). You could also look at animated full screen color noise/static patterns. This would improve uniformity by fully charging the components for remaining pixels. (ex: The old and free ".js" file version of jscreenfix. Present version is web based and not full screen).
If you're worried about being blinded by the high HDR nits, don't be.
The intent of HDR is to NOT cap peak brightness and provide a fixed gamma transfer function (layman: How bright something is relative to your display's darkest possible black and brightest possible white).
To explain what I mean, let's say we have two identical displays with an impossible 100% for color accuracy. And let us assume we have a perfectly mixed movie for both SDR and HDR (alot of movies are only graded once from the source material and then that graded copy gets regraded for the other releases. Basically this is bad but most movie studios are either trying to save money or simply don't care unless it's a "blockbuster" movie....
So again, let's say he have a perfect SDR and HDR release.
Side by side they will be 90% identical. The "HDR" levels are ONLY for specular highlights, like light reflections water/chrome/etc, clouds, sparks and other generally small details. Having something at 10,000 kits that is only, let's say, ~30x30 pixels isn't going to appear blindingly bright but will appear brighter in relation to the pixels around it (which again is the whole point of HDR).
Now for the other three screen modes...
Despite what you think you're seeing, CINEMA/PHOTO/BASIC MODES ARE NOT "TOO RED". ADAPTIVE DOES HAS TOO MUCH BLUE.
Adaptive is default, and by the time you get to the display options your brain has already adapted to this colder color temperature and you perceive the change as having too much red.
Instead of trying to explain why this happens, look at THIS ILLUSION.
The biological and science mechanics at the core of this illusion is exactly why you should NEVER compare colors by sight alone, and this is basically what happens when switching back and forth between modes after adapting to one mode. The rods/cones on our retina are not digital and takes time for them to adapt to changes in stimulation to light entering your eyes.
It appears this way because most displays come from the factory with a cooler color temperature than the industry standard D65 white point. This makes displays look better on a showroom floor under all their fluorescent lights. Simply put, if you think it's "too red", it's because you're used to seeing something that's "too blue".
Actually use these other modes for a day or there about so you have put real hours into looking at the screen, not just a few minutes of the day. Then try switching back to your adaptive settings. You may be surprised to find your opinion to be different about the other modes being too red.
This doesn't mean you can't prefer adaptive mode's saturation boost and/or cooler warmer temperature (aka a more "blue" screen), nor am I criticizing anyone who does not use Basic.
I'm just presenting fact, and not my opinion, based on data in regards to accuracy.
Personally I use Cinema mode and only switch to Basic for drawing.
TL;DR:
Adaptive has terrible accuracy, doesn't have a D65 white/color temperature, uses an HDR colorspace for non-HDR content (this is bad), and two levels of built-in saturation boost (RGB slider controls effect only one of these boosts).
Straight from the factory basic has color accuracy rivaling even the best ISF calibrated displays with a 3D LUT, has D65 white/color temperature, and uses same SDR colorspace that non-HDR content was made with.
I've done my own measurements with my own calibration equipment, and my results support their findings. Not that I doubt their results, I mean DisplayMate is known in the Home Theatre scene for their technical articles. If you don't agree with them then do your own measurements to get factual data for comparison. Human eyes are lying sacks of crap (read: adaptive) and you can search AVSForum if you need explanations and/or proof of this.
Here is DisplayMate's shootout for anyone enterested.
http://www.displaymate.com/Galaxy_Note8_ShootOut_100.htm
Just turned my phone to basic. Looks a lot better now. No more super bright cartoons colours. It also makes the colours of my graphic design logos more accurate.
I've always used Basic mode in all my previous Samsung devices inc my tablet.
However, the basic mode on the N8 shows a pink hue which is not tolerable to my eyes. Now, if the basic mode showed a true warmer tone like a slight yellow hue it wouldn't be so bad.
Talking of which, I was always under the impression that the term "warm" in respect of display technology meant whites would appear somewhat yellower , not pink like this display. ?

If you're trying to compare how the screen looks by your eyes alone, you're doing it wrong. Look at Illusion link in my long post.
How that illusion works is the best "short" version of explaining why you think Cinema/Photo/Basic looks pink.
If you really want to know if the screen is in fact too red, or too blue or even green, you need to use calibration equipment (colorimeter, spectrometer/spectroradiograph, and software; HCFR and DisplayCal are free, Light Illusion, CalMan, ChromaPure are expensive.
Getting your own gear is quite costly, but you might be able to rent it for half a day or so for a fraction of the price. If anyone is even remotely interested in this go to AVSforums.
I've actually measured 5 others (1 European and the rest USA variants) besides mine (Korean version), and every one was within the repeatability tollerances for my i1d3 pro. I don't think there will be any differences from manufacturing randomness due to how accurate they are straight from the factories, and I feel the same for any regional differences.
I'm not trying to offend anyone, but you are extremely likely to be wrong if you think Cinema/Photo/Basic modes are too red/warm using your eyes or another display as reference. Human eyes will adapt to warmer or cooler color temperatures regardless of accuracy, and factual data from tools all point to those display modes having amazing accuracy (See DisplayMate's shootout).
As for the question about color temperature...
The visible spectrum of light the typical human eye see will see more green colors than red and blue combined.
Blue is the portion we see the least of.
D65 is the standard white point which is based on the spectral pattern of light from the sun.
Since white is all colors, having D65 white means colors will interact with other colors realistically so there is no drastic change in perception around other light sources like tinting only under fluorescent lights but not incandescent lights.
Warm and Cool are how we describe which corner on a CIE chart a white is closer too in relation to where D65 is.
The above isn't totally true, but I didn't want to go into detail, but it's close enough I think. See AVSforum for the truth from people far more knowledgeable than I, like real ISF certified calibrators, Calibration hardware/software companies used by movie studios and scientists, etc).
Try using the phone for a couple of hours straight while set to Basic, then go back and change it. Do you still think it looks pink?
Before I forget again, it's possible a screen protector can cause a tint, as the material of the protector and any coatings it has (polarization, anti-glare, oleophobic, etc) will change the spectral distribution of the primary colors red/green/blue. This will change your perception of color based on your environmental lighting. So it could look perfectly fine in one room of your house and different in another if they had different types of light. That's just an example, as there are so many types of lights and each have their own color temperature and spectral distribution. Not just like incandescent vs fluorescent lights, but various types of incandescents (size, shape, power consumption, bulb material, diffuse coating, etc).

Android does not have any real color management, so you can't really calibrate the screen.
It's not really needed with this models' display, from the factory they are one of if not the most accurate displays you can get. It is on par with OLED displays with a 3D LUT that are used by movie studios for color grading.
Take a gander at DisplayMate's shootout for the Note 8. This is a technical analysis made by DisplayMate who's business is dealing with grading level accurate displays for those studios.
I just realised I may look like I'm advertising for AVSforum. I'm not.
It's just that what XDA is to Android and related stuffs, AVSforum is to home theatre and related stuffs. Actually they're better as they actually have active "official" members of the industry and not representatives. It's great being able to talk to people at or close to the source. I say active because they're not just there to advertise or sell you something. You can learn 99% of everything about calibration, for free, from the same people who's job is calibration or ISF instructors who hold paid or college classes. The equivalent type of people missing from XDA would be like engineers, lead techs and top level technical people from smartphone divisions from all the companies.

I think for colour accuracy it also comes to personal preference, like for sound equalization.
I used mine initially in the AMOLED Photo mode but did notice that colors were oversaturated. I've since switched to Basic mode and so far prefer it to the other modes. No, it isn't perfect, but whites are more white than Adaptive mode and colors are less over-saturated than the other modes. AMOLED Photo would still be my second choice. Adaptive mode has whites that are much too blue.
I found amoled screen to be really dependent to orientation. In the best one it is better than IPS and in all the other ones it is worse. They really got to fix this.

Accuracy is NOT and NEVER WILL BE personal preference (unless you prefer accuracy, lol). Preference is an opinion, and has nothing to do with the truth. I prefer Cinema mode, despite knowing Basic is the most accurate mode for all content shown on the screen (HDR will trigger HDR mode, which use completely different settings.)
In this case the screen accuracy is referencing the standard it was made for (BT.2020 and Rec.709).
You're free to think Basic looks too red, but there is a 99% chance that you are wrong (<1% chance due to bad screen protector materials/polariaztion filter/dot matrix/oleophobic & other coatings and your environmental lighting).
Again, the screen is one of the most accurate displays ever made. Take it to any calibrator (not "geek squad"...) and they will get the same results as DisplayMate... assuming the calibrator has a spectro to profile his meters to the amoled screen.
I won't even get into sound. I'll just point everyone to Head-fi.org forums as well as AVSforums. Way to many variables to cover, even for IEMs which take your "room sound" out of the equation. Both places will do a far better job at explaining the science behind everything for audio and (digital) visual things. And yes, real science. Everything I've mentioned has hard proof (measurements) and not ancedotal or biased opinion.
None of this means you can't like something that's "not accurate". Just wanting to make it known that yes many don't know what they're talking about (Not trying to be rude here. Just sayin').
Bs, who tells you I have the exact same eye as you. Who tells you present measurements or even science covers whole phenomena variables (plus Godel and other scientist prove science can't completely theorise a phenomena).
Unless you have attended to MIT or Princeton chances are you haven't achieved science study level I have.

This is probably true, however, I grew accustomed to a more blueish white, that the basic mode appears too warm now.
I remember last year, after trading my Note 7 for the second time and going to the LG V20, that I thought the LG had a way too bright white, noticeably more blue. However, after having had that for about a year and finally switching back with the Note 8 a few days ago, the basic just doesn't feel right anymore. I really like the adaptive (that is, with a few minor adjustments to the sliders), but whenever I am in a game or watching something, then the adaptive mode has way too much saturation. Then the only thing that does help is switching back to Basic mode, but I get annoyed by how warm it appears to be as soon as I hit anything with a white background (like settings or text messaging). The laptop I'm writing this on also has a more blueish white, my Samsung SHUD TV seems to be somewhat in the middle of it all but less red than my Note.
While basic may be the best setting, I can't say I really like it. Switching back and forth between the modes is a workaround, not really a solution. I really want to like this phone, but it is quite an annoyance to me personally, even more so when I consider I'm paying 950 USD for it. I am going to give it a few more days to see if I can get better used to basic mode or if I am going to return it to the store. It saddens me a bit that there's no option to add a little bit more blue to the basic mode, which, to me, is really all it needs.
I would also like to add more blue even to adaptive mode.

This is probably true, however, I grew accustomed to a more blueish white, that the basic mode appears too warm now.
I remember last year, after trading my Note 7 for the second time and going to the LG V20, that I thought the LG had a way too bright white, noticeably more blue. However, after having had that for about a year and finally switching back with the Note 8 a few days ago, the basic just doesn't feel right anymore.

Although a different device, the basic mode on my Samsung tab S2 LTE is awesome. It's a night and day difference to the Note 8 , albeit both adaptive modes on both devices are closer in my eyes . However, the basic mode on the tab s2 doesn't go pink but a more warmer yellow type mode.
I agree with you , the basic mode in my eyes on the N8 is rubbish.
