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.

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.
I just found this on you tube, http://www.youtube.com/watch?v=0a8aIGeLERg many people find this a problem.

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....
Hey there,
I just bought a GT-N7000, and I am quite dissapointed with the display quality. I have a lot of experience with Super AMOLED (plus) screens from Galaxy S and SII, but I am facing an issue on my new Galaxy Note.
You can see it on dark pictures, photos or mainly videos. It looks like the screen on the Note were more sensitive of brighter tones of black then the screens on S or SII. Let's say I am watching a video. If the scene is full of light, everything is all right and you can definitely see the breathtaking quality of the Super AMOLED screen. But when the scene goes dark - everything got different. On the S or SII, all the dark led pixels were inactive, so the screen was absolutely black on dark places. But, it looks like my new Note is a lot more sensitive of light, and the result is, it finds a not-absolute-black places all over the screen, and the scene is not Black at all. There is around 50% of the screen's area which is not Black, but just dark grey, consiting of small squares. Also, these squares flicker in a very high frequency, which makes it even more annoying. This is also happening with photos taken in dark, but, of course, the squares are stable.
Are you facing this issue too or am I the only one? I hope you did understand my words, if not, I could provide some photo samples of what I'm talking of.
This is called black crush and present on all Note 1s to varying degrees. Samsung refused to acknowledge it as an issue.

Search for the thread in the n7000 forums with 'black clipping' in the title If you don't find it as black crusg. Lots of good reading there. You will find all the info you desire in this topic.

Hello, I have a question about taking pictures on the Samsung Galaxy S9. I'm having trouble with is capturing the color of my children's' eyes. I'm not great with a camera, but have tried turning off the HDR and changing some of the other settings. Any help is greatly appreciated.
My old phone shows more of the true color of my daughter's eyes, which are a light blue-grey. My new phone (S9) with the HDR off and in "Auto" mode can't really differentiate her pupil from her iris (same problem with HDR on). I changed the white balance to get the color of her eyes to look more like what they really are, but everything else gets washed out. In another picture with the new phone, even though her right eye is more well-lit, it is very hard to distinguish the pupil from the iris. The left eye still isn't great, but is showing the color a little better. Since I'm a new member, the website won't let me link to the pictures.
I just upgraded to the S9 because my old budget phone wasn't taking good pictures in low light and now that my wife and I have kids, I figured I'd want some higher-quality pictures. Other than this issue, I'm impressed with the camera.
Thanks in advance for your help and have a good day.
Hello!
When there is a yellow warm street lighting at night, the camera makes very yellow images, for example - the sidewalk color is grey but on the phone screen and on the photo taken the images are super yellow. My phone camera on standard colors, i tried to take photos on auto mode and on night mode- results are same. Can you please confirm if your phone does the same?

i can confirm, some night shots with yellow lightning makes not good pictures. overall im little disapointed to this p30 pro camera.. i had mi9 before this and im thinking back to that.

The camera is great except this condition when the lighting is yellow. I tried on pro with 2800 white balance - it is the lowest, but it is still yellow.
Confirm. Also, in the room when illuminated by fluorescent lights, the colors also go crazy.
Those types of light sources are challenging to measure the correct white balance of because their frequency updates vary a lot. Most of them will look yellow because that's the colour they emit at night. It's not really a bug but a choice each developer makes how they will meter those types of light sources. You can easily compensate for the default measurement by shooting in Pro mode and setting your own white balance value or even your own Kelvin value.

ו tried it. The lowest is 2800. It is still very yellow.
on p30 the same problem with street lighting
For me white is white
White even if the corridor light on the right is a little yellowish with human eyes
I am making war to this phone for this ****ty yellowish tint on every photos made after sunset with street light, or even inside home with some light. I regret to not buy OnePlus again...
Taking same shot with OnePlus 3t (3yo phone) give the right color output. I can't believe that Huawei are not able to adjust and calibrate this sensor in a better way. Camera phone? Absolutely not... Not to mention the photo quality of wide angle when light isn't perfect, noise everywhere.
I hope will get better with Emui 10/Android 10
Sometimes it doesn't even get better with editing. It's ridiculous, I'm very disappointed.if you are lucky you can recover 70% of the shot losing times with editing... When I pass to OnePlus 3t (even if it's not a camera phone) I almost stop using Photoshop, now... I'm using too much.
Honestly I really don't understand why 97% of reviews doesn't analyze and report this problem.
Very very strange or maybe you are having a hardware issue.
See what I took in out of the pocket conditions.
P30 series using RYYB sensor in main camera for collect 40% more light while other phone+camera using RGGB (basic primary colours).
so yeah, It's best for low light but you got yellow tint +warm color(red orange yellow) shift instead. I saw Huawei try to fixed it since 9.1.0.12x by software process but they can't
btw, They try again on Mate30 by put +UWA(RGGB) same pixel size at main cam(RYYB) (for color comparable on something? i'm not sure) while P30 main cam had different pixel size to UWA. but Mate30 can't take macro picture cause that bigger pixel.
look at this video for color shift problem
like China flag, flower, whatever that have red-orange-yellow color

Not always, but I notice that raising iso get worse. Honestly I think that software can help, expecially with AI.
I don't know the condition of the photos you posted but it's good
Just for saying, the 16:9 shot is made by OnePlus 3t gcam Nightsight (3yo phone), the 4:3 is made by P30 Pro.
Yellow tint corrected by post-editing, but just look at the shot, I really like more the OnePlus with gcam... A 700€ flagship camera phone wanted by older (not camera phone) phone? Disappointed...

AFAIK, if you take photos with some warm light (yellow, red..) as a background light (dominant light), the overall result will be turned into yellow tone photos. When I looked at your photos, I saw that the buildings, streets, in where you are living, are always covered by a warm color. That's why the algorithms of P30 pro will cause this issue. This is also an explanation for the photos a guy posted above without any problems.
P/S: Did the latest update (emui 10) fix this problem?

i wouldn't call this an issue at all.. this could be fixed by an software update, since its the hardware in the phone, a different sensor which captures way more yellow details than other phones, but thats a good thing, because yellow emits way more light, and thats why the p30 pro is able to produce soo good low light shots!
i don't mind lowering the yellow saturation through lightroom, because the cam simply gives you beautiful shots with good detail, even more than you see through your regular eyes at night. Go buy another phone of you are more happy with the shots they produce instead of sh**storming about the camera

Yes, that Is what I thinks so, that Is why I'm mad ti Huawei. I can't belive that with lightroom in postproduction on JPEG file you can almost fix the Yellow tint, and the software Is not able ti do It himself, expecially with all the hype on AI. Is this AI so stupid?

I am now reading the second part of the message that I miss. Dear fanboy, if you are happy to have spent 1000€ for a smartphone sold as a cameraphone that has serious difficulties in the color management good for you. Sincerely coming from oneplus 3t (an old phone and never been a cameraphone) I am disappointed in some conditions since the 3t with gcam is better. Look at the mate 30 pro, same sensor way better job... I repeat if you are happy to often have a yellow tint and have to manually retouch the photos, be happy and be the champion of Huawei justice elsewhere. I can't afford to buy another phone 3 months after buying this since it has already lost € 250 from the amount I paid for it. Greetings and happy new year.

Dear oneplus fanboy,
i don't actually carey since i have my own opinion, all op phones are struggeling to achieve any kind of similar zoom, picture quality and night pictures. If you are not happy about the yellow tint, fine, i can live with that little postprocessing "problem". Go rage about that elsewhere, i'm more than happy what the phone offers, and that matters - i had multiple phones, from oneplus to samsung, no way i go back. I'm glad to say i spend 700€ for my P30 Pro, and i do not regret a single thing - if you however feel it was a mistake, then be happy with your Oneplus 3T and stop whining about your "loss"
Regards
Can someone else confirm that Redmi Note 10 Pro has a Black crush display issue when watching dark videos?
My device has the issue and dark scenes are unwatchable.
What Is “Black Crush” on a Display?
Have you heard the term “black crush” while looking at TV or monitor reviews? The problem is getting more attention now that display manufacturers are trying to improve black reproduction, particularly on LED-lit LCD models. So what are “crushed blacks,” and do you need to worry about them?
