After struggling with my S9+ and it's black crush problem (I returned it for this reason) I did really hoped N9 doesn't have such a problem.
Well, yesterday I tried my brand new N9 with Netflix (Luke Cage S2) and there's definitely a black crush issue!!!! Anyone else noticed?

Last night I tried some more test together with my OP6 and sadly I can confirm it! You can see in the attached files, the upper phone is the Note 9 while the lower one is the OP6. Both phone are on 50% screen brightness. The Note 9 has even the Video Enhancement enabled and I tried all the screen settings (adaptive, cinema amoled, pitcure amoled and basic) without any positive result. I took these pictures with my iPhone X and I can tell you for sure that the problem is even more evident in person!

Yes, unfortunately, I am experiencing the black crush problem on my Verizon variant. I also experienced this problem with my previous T-Mobile Note 9. The screen calibration app from the Play Store does help, but for a phone this pricey, this software quality control problem is unacceptable.

YES. That’s why I returned it. It’s incredible even considering that S9 had exactly the same problem when it was released. I really did think this time samsung could take care of it....but I was wrong.

Mine's going back today. And, unfortunately, I'm giving up on Samsung with these phones. It's too bad, beacuse everything else has been stellar, but my typical use case makes for this problem to be too significant and too frequent to overlook ?.

not exactly what i said either.
does removing auto brightness and adjusting it a bit more help?
because it just seems that's the issue.
edit:
i did tests with the note 9, note 8, and note 3
while there are slight differences between each device nothing like the pictures you posted.
all screens had auto brightness at off and brightness at 50 percent which was more than enough.
lets not forget 50% on a samsung and 50% in another brand might not have the same intensity/range.
and something obvious but i feel i must add in this case is that samsung phones when video is paused will auto dimm the screen a couple seconds after playback is halted.
in order to do your tests i figure you also paused playback. i just hope you didn't take pictures of when it was dimmed... because lol well that would be dimwitted.
when i compare one phone dimmed and one not dimmed i get the exact same results as your pictures. a brief touch of the screen restores normal brightness.
I have a little black crush on mine. But some people forget we are watching stuff on a mobile device that is packaged for small screens. The video is compressed and sometimes even the data.
I made sure to watch some high quality content, not just 1080p or 4k. Dim and well lit content. Also, a wide variety of YouTube videos. I experienced some black crush and many times brightening the luxury of the screen helped. To conserve battery some content I don't need to see all the details. Other times I knew it was compression compressing all the colors and shades out it.
The best way to test for black crush are contrasty pictures. I see many of the complaints about videos but sometimes it can't be helped as I'll watch the same content (same exact file for scientific reasons) on my JS9500 which is semi calibrated and Bam! there it is still. I've tested some with the camera and sometimes I will have slight black crush in darker pictures but it would be a challenging picture anyways. Sometimes black crush is non contrasty dark content and/or compression and codecs.

You can see what you want to see. I don't care.
If you want to believe that I took pictures of two phones letting one dim itself just to waste my time here writing this post...well do it.
I owned all Samsung phones since the first galaxy...let alone the many other phones I owned...S9 plus and Note 9 have such an issue. I read that S9 was updated back in may to solve it (although some say it's not solved at all). I don't feel like waiting 3 months to see maybe this problem solved. I paid a lot of money for note 9 and as I did for S9+ I decided to return it for this reason. Nor I feel like crancking all the way up brightness just to be able to see some details in dark areas nor even up to 60 nor 70% (thus you feel better?!?) when my other phones don't have such an issue (nor even my s8+ and note8).
Maybe for someone else this is not a problem, especially if they don't use the phone to watch movies or series on Netflix or other streaming services. I do. And I don't waste a thousand euros for something that won't let me see a decent image quality.

Oh well....my others mobile devices packed for small screen don't have such an issue. And I can watch whatever I want...but one has it and the other one doesn't.
There cannot be compression when we are talking about the same video on two different phones one showing the issue while the other one don't. I mean I even posted pictures showing the issue. And believe me when I tell you that they don't make justice to the real difference between the two devices....it was really worst in person. I don't need to be convinced of the contrary thanks.
Maybe the most clever way to answer could be "sorry pal, you got a lemon". I cannot exclude it (although after owning S9+ with the same issue I'm a bit suspicious about it). But no settings nor codec nor compression.

Lol. Drinking orange crush and Bombay Sapphire.
that brightness slider must be really heavy. wonder which is more difficult:
- moan about it and return the device
or
- move it 1/4 of an inch to the right. (that's 6.4 millimeters to you)
so can you take a picture of the same scenario as before but with a bit more brightness? its for science
now take an other picture of both phones maxed out. its for the win

Seriously can't work this one out, do I get my screen changed or not?
Should I wait to see if ICS makes it any better?
This phone is perfect for me except this issue with the blacks / greys. Even when i zoom in on dark parts of pictures taken with the phones camera it turns into a pixelated mess, so this is defiantly not a low quality source issue, its hardware or software related, but which?
Advice please guys. Many thanks!
I know! Right?
The screen Is freaking awesome, simply the best on any smartphone, but why those blacks haven't been fixed yet???

I really am at a loss to what you guys are complaining about. I'm either not that fussy, or deluded to the fact that what I think I am seeing as 'bad' I pass off as something else.
From what I've read around the forums, what should be a shaded series of greys/blacks in an area are appearing as blocks of black/darkgrey instead of a gradual change.
I've always thought this was down to how videos/images where compressed or decompressed and displayed - which would almost certainly be software and not hardware?

Same here. My blacks look fine most of the time. When I do get grey blockiness I'm pretty sure it's due to poor compression in the video file, because other videos, large black areas look fine.
Can anyone give a link to a video available online in which this problem occurs (and the point in the video we should be looking at).
Maybe then we can get some objective testing with everyone using the same source file.
Maybe even have people doing screenshots to compare screens.
http://forum.xda-developers.com/showthread.php?t=1366014&page=4
I'm rarely using my phone in dark enough conditions to notice.
ICS should improve gradients, but won't fix the black crush if it is indeed a problem with the screen hardware.
I am probably going to regret this, as my Note was perfect except for this black crush issue, but I sent mine back to be replaced. And the issue was not just on videos for me so poor quality encodes are not the problem, I was getting it even with pictures taken with the phones camera. Said pictures taken with the Note displayed fine on my pc and my wifes Galaxy s 2, so it is deffo a problem with the device.
Please lets not turn this into another "who cares" or "its not that noticeable" debate like the other threads, all I am aiming at with this thread from now is to find out if there are any Notes in existence that do not have this issue!
Thanks.
I refuse to look for a problem that is not there.....
There is no phone or portable device in existence that is color accurate, either tonally or temperature or gamma correct out of the box, and to expect such is to be, well, expecting quite a bit too much.
Why do i make that statement?.. Well, given that a monitor or TV at ANY price are not accurately calibrated.
To get an accurately calibrated monitor requires a display worth using, then a color tone/temperature/gamma calibration system (which is ~$200 & up) and software that can use the resulting calibration profiles...
The SGN is a phone... tbh there is no "fault" or "problem" here, other than unrealistic customer expectations...
Would a settings app that could set globally set color temp & gamma be helpful? sure.. there is enough color temp variation in the spread of production tolerances in phone to make this useful... stop a ll the pink white /blue white issues
But will it make the SGN a color accurate display?.. no.
So... lets wave a magic wand and make it so... whats the point? the camera does not justify it, the movies you watch are overly compressed and not color accurate (never mind compression artifacts of banding, blocking and shading), youtube videos have no quality controls.. online TV, website videos and stills have major color saturation issues.. so what content will you access that is going to be useable on a color accurate display?..
well, 4 beers down and 2c more spent..

Dude, my pc plays / displays these movies and images fine with no artifacts, as does my tv, as does my partners Galaxy s 2, as does my Nexus s, so how can you say that there is no problem?
Anyway, I just had a look at my cousins Galaxy Note and that one is playing these movies fine, and is displaying the pictures taken with my Note without the chess board effect, so if you are happy to pay over £400 for a defective device thats up to you, but many of us expect to get what we paid for.

The problem is clear enough to see there, but it's not one I've ever noticed on my Note. I just tried playing this YouTube clip on my Note....
http://www.youtube.com/watch?v=syxd2n8S4AE
and could see nothing wrong with the video performance in a darkened (curtains drawn during daytime) room. I wonder how well this clip plays for other people on the Note.
I made a video of the Note playing this clip and I'm uploading it at the moment. It will take a while (81 minutes remaining at the moment) as I shot in 1080p. I'll post a link when it's ready.
FWIW I'm on the latest official ROM and my phone was sourced from Germany in early November. From my perspective there is no problem, which might make it quite hard for Samsung to fix.
My Note is running on ICS (CM9) and the color rendering is substantially improved over stock GB. Gradients are smoother and blacks are rendered cleaner.
My video is up.

I've played the same clip on my Note and it looks exactly like yours, no banding/crushing/clipping whatsoever.
I've tried a lot of Youtube clips and movie trailers but in only one of them I could see obvious artefacts during a fade out. I played the same clip on my pc and saw the same thing happen there so that's probably just lousy encoding.
Thanks for putting that video up, I hope my replacement looks like yours, its due tomorrow.
I got me new note, this one is set to uk language instead of german like the one I returned. It has the exact same issue, drops from 4 grey to 3 complete black and i am still getting the clipping, bloody Samsung, this was meant to be an upgrade from my nexus s, but most stuff looks better on that! Not gonna excahnge again, I will wait for ICS and see if Samsung actually acknowledge the issue.
@Mystic38. Whilst I agree with you that most consumer devices don't come calibrated to industry standards and that most consumer devices lack the essential settings found on the most basic of professional displays, I fail to see how any colour, contrast, hue, gamma or brightness calibration would affect the overall appearance, unless of course you are cranking the settings beyond anything useful and crushing the dynamics intentionally.
It's difficult to introduce visual banding or blocking in high BIT rate video or lightly compressed images by tweaking settings and calibration by a couple of percent alone, as there are near on 17 million colours. This leaves thousands of grey levels to play with and the human eye shouldn't notice banding or blocking with that many greys.
This presumably points to an issue with the way that video is presented to the screen driver or how the screen driver drives the screen. There's probably an issue with crushing where the hardware converts the digital signal to electronic levels of each AMOLED element. I have seen this problem on other devices, not just phones and most of the time it was rectified after a software upgrade.
Another thing to remember is that companies like Samsung are fully aware and accommodating of the fact that a lot of people now use these types of phones as monitors for photography and video production as I do. I use DSLR Controller and have no problem with crushing. Using the phone as a monitor has been extremely helpful and negated the expense of something which would have cost over 10 times the price.

I just got round to trying the ,png gamma test file on my Note. It fails the test. Everything below 4 is black and as you go through the numbers from 4 and above there are bands grouping four levels into one tone. Worse still, the tones alternate from greenish to purple instead of being shades of grey. Interestingly if I perform a screen capture the capture is a true reflection of what I see, which implies to me that the Note is actually sending bad values to the screen rather than a hardware problem, because surely the screen capture only cares about the data, not the physical appearance produced.
Looking at the same file on my laptop everything is presented correctly, so obviously the file is not the problem.
Yet despite failing this test I have never noticed a problem with the Note to cause me concern in normal every day use.

Have you viewed it in the gallery or in a browser? With my Note everything below 4 is crushed in the stock ICS browser but I can see everything in the gallery.

I think the gallery uses a different color gradient and temperature than the stock ICS browser, much as if you view a rich encoded black contrast video on the stock video player and on a custom app video player like MX player... you get varying results...
I think this issue is a mix of both a hardware and software one, and though the Official ICS upgrade "might" alleviate this problem, I surely believe also that since this is a combination of a hardware problem, the clippings are still there but perhaps not quite noticeable anymore....
After watching a YouTube video from the app and I go back to the home screen everything is over exposed. the only fix I found was to lock and unlock the screen again. Anyone else having this problem?
I had noticed this once before when using Google Now but I wasn't aware what had caused it. At first I thought it was just the screen but now that I tested it with a youtube video you're right. When it screws up the colors it is really bad looking in Google Now because GNow relies on such a subtle distinction of colors, like the grey on grey. When the screen is working normally is looks fine but after a youtube video it looks really bad, the two greys meshing together. I'm really glad it's just some software issue. I remember looking at the screen once and thinking man those are some bad colors but the screen is really pretty nice when it's working properly.
Yes i do notice the same thing hoping Google comes with an update fast glad to know is not just me

I'm curious, I'm not seeing any of this and am wondering if you guys are running your screens at full brightness or something.
I have my N7 set to auto most of the time and am not seeing these types of contrast issues.
Sent from my Nexus 7
My Nexus is stock (but unlocked and rooted). I run my Nexus 7 almost all the time at 40% brightness.
I get this over exposed looked after playing most videos. Happens with YouTube, Play Movies, Gallery, pretty much any videos from any source. Turning the screen off and on works. Or I could just wait an minute and watch the screen gradually fade back to normal-ish.
This isn't my only issue though. My screen also seems to be poorly calibrated. Even without the video playback issue, some of my colors are faded, and whites are over saturated all the time.
Don't know if the two issues are related, but I'm going to try exchanging it because some people say theirs doesn't have these issues.
PS. I don't use auto brightness, that makes my screen way too dark (seems my auto brightness setting keeps my Nexus 7 at minimum brightness most of the time).
I have this issue (as well as minor screen separation), but can't replicate it consistently.
I just assumed it was the screen just 'waking up' from full screen mode, it usually goes to normal after about a minute.
Rarely i see a minor screen flicker/ or tearing (sortof like oldschool CRT television flicker on a few scan lines) during this 'recovery'

nope. brightness set to around 25%. like others, I can't always replicate but it usually happens after watching videos. locking and unlocking the device immediately restores normal contrast.

I have the same issue with my N7. Android 4.1.1 completely stock, out of the box. It seems to be a problem with the hardware decoder as using software in MX player does not seem to trigger it, but the gallery player does. I see this not just after video playback, but around 5 seconds after starting playback when I begin to notice I'm losing so many details in highlights. A white contrast test on www.lagom.nl clearly shows the horrible detail level. I hope they fix it soon.

Another thing is that it only happens if you watch video in full screen. If you watch YouTube video not in full screen i.e. in portrait then there is no problem of over exposed colors.

Looks like it. Don't worry about it though, you probably won't notice it in normal use.
mine is so noticeable when I play darker movies like Dark Knight. All the black clips It's so sad. I haven't read enough to find a work around, and I don't think there is one.
Do new Notes 1 (the N7000), ones produced recently (eg. 3/6 months ago) still have this bug? If yes, is the display better than displays of 1,5 year old Notes?
I have the initial release of note and thank God never experienced any such thing.

Hey guys, first time poster here.
Got my P20 pro about 5 days ago and one major thing I'm noticing is I can't look at the phone for too long because it really starts to hurt my eyes
I was wondering it might be tied to the refresh rate. Does anyone know what it is for the phone?
Logging into youtube to watch a video at 1080p does not state '60fps' on this phone, but does on others.
Does this phone have a sub-60hz display?

I get the option on my P20 pro for 1080p 60fps
1080p 60fps
Mine does say 1080p 60fps, the refresh rate on this phone is 60hz, thats weird. did you updated your phone, if not what firmware version you have. i never experienced something similar.

Yep it's on the latest version
Which version is your firmware?

No, i mean your android Firmware, Mine is 8.1.0.131 , Go to Settings>System>About phone > Build number.
Yeah I mentioned above, 130 firmware
It's not the refresh rate of the screen. It's probably because you have such a wallpaper that in the lowest brightness setting emits an uncomfortable blue light radiation. The refresh of the screen is just fine. As for YouTube, it supports 60fps if the source video provides it. I've noticed the same thing in the watercolour theme when the brightness settings where in the lowest point inside a very dark room. Apart from that situation, my screen is super confi in every light situations. (and when i changed me theme for a darker one, even that problem was solved)

Ahh I see. What a weird behaviour.
It's worth noting though that it's uncomfortable to look at on all brightness levels and with the use of eye comfort mode.
I'm starting to think it's just my eyes.
But on my many other devices I don't get the same problem
If your internet is kinda slow, youtube could remove the 60fps option for you.v
For me, I only noticed the irritating wave length emission only at the lowest brightness setting in watercolour wallpaper. It may have something to do with the specific colour and the lowest possible brightness setting. I must note, that it has a very low brightness setting as a phone. That's a good thing at night. My oneplus didn't go as dark as p20.

Ever since I got my phone it was able to playback 60fps YouTube videos. My firmware is currently (.130) Keep in mind it was still able to playback 60fps videos with older firmware.
You can always try going to www.testufo.com and see what refresh rate is this playing in the test.
With my Razer it shows as 120Hz but you should see 60Hz showing up.
With my Asus tablet P01MA it shows up as 30Hz.
Of course it's 60hz

This exact same thing happened to me with my Mate 10 Pro. It really hurts my eyes in such a bad way that I have blurry vision after looking at it, and some weird head aches. There is something wrong with these phones. I just ordered the Mate 20 pro but I think I will send it back. This needs more investigation.
I didn't expect 1000€ device still has this issue.
If you want to test it on your note 9 download this image: https://i.imgur.com/DUEKJzH.jpg
It is dark solid grey background.
In dark room open this image and set brightness to low. You should see uniform gray color.
I think at least 90% devices has this problem.
Here is what I see:

Feel free to enlighten me but unless you spend all your time looking at a dark solid grey background, I don't see why this is an issue. I have tested mine with a similar image and to my eyes, the screen is perfect.
Your link to the image is dead btw.

Many apps has dark gray background. First I didn't test anything I just noticed it in youtube app - dark mode. Its quite disappointing.
I tried all three links on another pc and they are working.

While they do have a dark grey background, there is usually something in front of the background to draw your eye to instead.
Thanks for letting me know about the links, it's amazing how editing your post, fixing the links and saving the post makes the links work. I did check the links and all I see is noise.

Not every time background is covered by content. I can clearly see difference on youtube app, top part of display is slightly lighter and greenish and bottom is darker and reddish.
I did nothing to the links. I just tried to add pictures (insert image) but it didn't work.
seems my note 9 does not have the issue u reported
see the pic u posted as screenshot from my note 9
No issue here.

Thats how mass production works. Or do you think im the only one who got exclusive defective device?

Actually, mass production usually aims for less than 1% failure rate, so I'm pretty confident you got one of those >1%.
Considering YOU are the only one complaining, then yes, you're probably one unlucky person.
If you were talking about a Google Pixel 2/3, then yes, you're likely to have a **** screen, because that's how they are. Samsung screens aren't like that at all - the Note 9 has one of, if not THE best screen available on any phone.

I am pretty sure they will agree to change it + the chances to draw again a problematic display are really slim. Sadly some do have such a problem and actually I saw a lot worse on the xda forums. Return it for exchange is my advice.
Look in my thread history. I made threads about Samsung display uniformity issues since Note3!
It got better over the years, but still I estimate only 10-30% of all Amoled screens are perfect.
Samsung makes things right in terms of quality management, because most customers do not notice this flaw, but if you are sensible to it, it's hard to ignore!
in my threads I also explained the reason for this, which is how amoled screens are produced. they are cut out of wafers after lithography. only devices cut out of the center of the wafer have almost uniform screens. the more from a side your screen has been cut out, the worse the screen quality will be.

I think it has improved a lot since a couple of years. Before that, I used to swap my Samsung phones once or twice to get a decent one.
But the last 4 or 5 phones I bought, all with Samsung screens, were all perfect.
That includes Pixel 2 (not XL), Note 9, S8+, P20 Pro, etc....
Either I got extremely lucky to get as many perfect screens in a row, or they really improved things. Now I think it will happen to me again to have a bad one, but I'm not as nervous anymore. It's not a lottery anymore.
My Note 9 in particular is extremely impressive with a perfect screen. Perfect whites, no uniformity problem with any shades of grey at any brightness. Pure oled bliss.
BUT, I've had so many problems before that I'll ALWAYS be a little nervous before unboxing an oled screen smartphone. I've been burned too many times with crappy panels.
Let me tell you I was extremely nervous the day I bought my LG Oled 4K TV 55"..... Thousands of dollars thrown at an Oled panel lottery.... I was lucky this time again
Times are changing.
Okay so I got another note 9 and has this issue too but in different spot. Also checked one more piece in samsung store...same.
So I think almost everyone has this uneven screen but maybe some of you have less sensitive eyes or just don't want to see this problem

So my question is, does this affect your use of the device? Is it causing wear and tear on you vision? Or is it just an OCD/OCPD effect?
To me personally, stuff like this is pointless to have an issue with even on a phone that costs $1000. Unless it's to the point where you can't use the device because you see the defect on everything.
To another comment I saw that included the word "Perfect," NOTHING is perfect, and there will never be such a thing that could be perfect because of our human definition of what perfection is. It's good to strive for Better, but it's pointless to strive for Perfection.
Btw, I did download the Pic and tested it on my Note 9 and my wife's Note 8, and the uniformity is affected on both devices. I also looked at the image on my 4K TVs and my LCD monitors and the effect is there. Are you sure the image itself is uniform?

Perfect screens exist. I have some. I have perfect eyesight. I was a combat helicopter pilot in the french army. I know what to look for. If it is there I see it. If it is not, I don't. It's a fact. It's science. Not some voodoo magic wishful thinking.
I've had terrible screens. I've had some perfect. Nowadays I get more good ones than bad.
Bad ones still exist, but it my opinion that they are less and less common.
Against clear backgrounds you won't see much apart from a slight shift in color temperature.
Against dark grey at indoor brightness you can have incredible differences between some parts of the screen.
If you use a dark theme (not black), you will see it all the time.
Does it prevents you from using the phone ? No of course not.
Does it suck on a 1000 dollars phone ? Yes.
Some people are insensitive to that kind of thing. Good for them.
It's not an OCD. It's the will to have a good looking screen.
I like good looking women. I don't think it's an OCD. I know what I want, that's all. And I want the best. Nothing less.
If you want to settle with average, good for you.

You do know that you have to have a perfect eyesight to be a combat pilot, do you ?
Acuity, color, contrast, night vision, side vision, field of view, and much more. Everything is tested BEFORE you're even allowed to go forward in the selection process.
Most people fail those tests. That's sad but that's life.
As a side note, you don't have to have perfect vision to see those screen problems.
They can be very obvious to anybody open minded enough.
Close minded people though, will always be impervious to such matter.

You literally missed the most important part of my original post. That's why I stopped reading your post.
And yes I do know you have to have "Perfect" eyesight to join some military air forces.?
And I hope you aren't calling me closed minded. I never said someone has to have perfect eyesight to see the differences of the pixels in the image.
Anyways, I'm done with this. Quite pointless now.??
