Omg, I really thought I was the first one to report it for the second time.

Somewhat unrelated. I was reading the wiki on xbox red ring of death and was amazed at what failure rate is "acceptable". 68 failed out of 100 during manufacturing tests... They finally claim quality control, manufacturing issues, product sourcing, distribution, quality of materials and so on as excuses...

By the time anyone even bothers some other device will be out and our issues will be moot. I.e. Enabling hardware video acceleration, supplying drivers, I've even forgotten what device it was...

You are right. Devices come out so fast that by the time they get around to this, the Note 2 will be out already.

Guys.. we may have something here. I'm not going to jump the gun here.. see what you think. On GB, I had a huge dropoff to black. You can see my original pics on page 4 (can't seem to find them on my computer).

I'm now running Sensation which is the port from the skyrocket.

There is still a drop to black but it is DRAMATICALLY smoother on this rom than on GB. Even though I can see 1 its a smooth drop to black. Thoughts?
[AT&T Samsung Galaxy Note I717] 00mred00:
I can't see them well...how are 1-7?

Maybe the same "ics" fix already present on the note version.

Hoping to try out sensation soon
[AT&T Samsung Galaxy Note I717] cgibsong002:
Smooth. This is clearly different from the other ics leaks as those had a drop off at 7

[AT&T Samsung Galaxy Note I717] 00mred00:
I pulled it up on a pc and it clearly looks better than the 7 drop

look forward to some darker pics. So far it looks similar to my note (which I don't believe has the problem as bad as the others)
[AT&T Samsung Galaxy Note I717] dvd7000:
Do you have the Netflix app? How does a B&W movie scene that has a fade in/out look? Are the screen borders around a 1.33x1 movie still jet black?

On You Tube (browser or app.) check out this clip (in 720p):

http://www.youtube.com/watch?v=0cay2dnuhcs

It has always looked the worst to me as far as black crush is concerned. Do you notice any problems with it now?
[AT&T Samsung Galaxy Note I717] paleh0rse:
If the Skyrocket roms end up looking better, then that may finally prove that this is a kernel-level software issue... I'm VERY interested to try the ported roms now!
[AT&T Samsung Galaxy Note I717] 00mred00:
wow that video does show it really well..even on ICS
[AT&T Samsung Galaxy Note I717] K2Biker0:
That video is completely unwatchable on my note. hopefully the official ICS will have some sort of fix in it cause its such a waste of a beautiful screen.
[AT&T Samsung Galaxy Note I717] bendotson:
That video is pretty poor quality when viewed at 720p on my 13" macbook air. It's not a good reference to use.
[AT&T Samsung Galaxy Note I717] paleh0rse:
I highly suggest sticking to the simple and easily-measurable gamma test image when identifying or demonstrating the problem.
[AT&T Samsung Galaxy Note I717] dvd7000:
It looks perfectly fine (black crush wise) on my Samsung Captivate.

I'll try to record what it looks like side by side and post it to You Tube later.

I have NO problem with compression artifacts from any source, but black crush will compound any compression issues the video may already have, and make it unwatchable.
[AT&T Samsung Galaxy Note I717] tyler79durdan:
I noticed that when using screen adjuster, as soon as you set the contrast above -1 the image becomes better, but the app is causing my ui to slow noticeably. If you look at the surrounding area behind the ui on the SA app, as you change the adjustments, it goes from deep black to immediate greyish. O = black -1+ = grey tinge. Aslo the same result with +color. I have it set to +1 colors and it seems to solve the problem at the cost of washed out blacks...
[AT&T Samsung Galaxy Note I717] cgibsong002:
There's crush still in that video but its not very noticeable unless looking for it. i didn't notice it at first. of course i've never seen it before so its hard to compare. there was noticeably less crush in the rusty nails video compared to before using this ported rom, but it was still there. still though, the before/after gamma ray test image definitely proves something. there was a straight up drop to black from 1-0 previously and now the drop is not significant at all.
[AT&T Samsung Galaxy Note I717] tenderchkn:
On the Sensation rom, is the black level the same? I guess my question is: is the "1" darker now than it used to be? There are two methods for "fixing" the dramatic drop off. The first is to make black "brighter" so that it is closer to the brightness of "1". The other is to darken dark grays to be closer to true black. Obviously, the first method would look terrible, so I want to make sure that dark grays are actually darker in your ROM than before.
[AT&T Samsung Galaxy Note I717] cgibsong002:
looks overall darker to me... What do you think? Still not as good as the focus though but maybe now everything is just overall gray and needs to be darkened? How can I try that?

Sent from my Samsung Nizzote
[AT&T Samsung Galaxy Note I717] tenderchkn:
I think we'll need to wait until it's dark to do a proper comparison. I'm very excited at the possibility that this begins to address the problem (which means a software fix is possible), but I can wait a few hours. :)

Have you tried looking at this in a dark room yet? The stock black level is such that, even in a dark room, you should not be able to distinguish the "0" box and the black bevel. But since you have a white phone, you'll need to be in a completely dark environment to see this. Or, I guess you can compare the "0" box to the same box on your Focus (if you still have it).
[AT&T Samsung Galaxy Note I717] cgibsong002:
Focus is gone.. Those pics were taken with the lights out but my blinds don't do much so I can't get proper darkness until night

Funny thing is... that is the first video I have seen posted that i could clearly see a difference between my note and our pc monitor at work.

Every other video/image showed clipping and crush across multiple displays

This one clearly showed it on the note but not on the monitor
[AT&T Samsung Galaxy Note I717] tenderchkn:
Alright, we'll wait then. Looking forward to the results!

You Tube DEMO:Samsung Galaxy Note BLACK CRUSH Demo [Compared With Samsung Captivate]

I had a little time so I put together a quick video demonstration of the Galaxy Note and the black crush problem that I have been experiencing, and posted it on You Tube:

http://www.youtube.com/watch?v=0a8aIGeLERg

I welcome any and all comments, suggestions, and criticisms.
[AT&T Samsung Galaxy Note I717] schrochem:
I'm just on stock with holo kernel

DVD that video makes the Note look like a POS when compared like that....
[AT&T Samsung Galaxy Note I717] cgibsong002:
Well guys.. don't know what to tell you, but I think I screwed up. Just took pictures in the dark and the pics look more or less the same as the original pics I took comparing the note with my focus... i.e. it looks like a big dropoff at 1. To my eyes though it looks better. Since I didn't take the pictures back to back its hard to say, but I'm thinking I was mistaken and it really isn't fixed.

Which brings up a different topic. IF my note still has crush, and I'm on a skyrocket port, and the skyrocket doesn't have crush... is this a hardware issue? Someone who knows more about this stuff might want to talk to the guy who ported the ROM and see what kind of changes he made display wise.
[AT&T Samsung Galaxy Note I717] paleh0rse:
What's interesting to me is that your dropoff on the Skyrocket ICS port is still between 1 and 0 -- just as it was with all GB roms on our Note -- while all of the ICS roms based on the i717 leak show a changed dropoff to between 7 and 6.

I'm not sure what that means, if anything, but it's still interesting...
[AT&T Samsung Galaxy Note I717] cgibsong002:
Yeah.. lol... I thought I had something but I'm pretty confused now. If it's a dropoff at 1 still through this ported ROM, like I indicated in my last post, does this mean it's a hardware issue? I'm using a rom from a different phone and it renders just as it did stock. It sure as hell looks like it. Of course this is one phone and could very well be an isolated issue, or it could just as well be the way it was ported over (i.e ported to have the same settings that the note does stock.. I can't comment on that.)
[AT&T Samsung Galaxy Note I717] jpeg42:
You are still using the Note kernel though.
[AT&T Samsung Galaxy Note I717] srtpusher:
If I go to YouTube desktop site and play 480p it plays fine. at 720p, I get some color banding but ZERO black artifacts. If I play in the app or on the m.YouTube.com site the black artifacts are HORRIBLE. I am on a stock rooted ROM.

I downloaded using tube mate and the black artifacts are the same as in the app. So what is different in playback?

[AT&T Samsung Galaxy Note I717] paleh0rse:
that's just the way some browsers handle the videos -- they don't try to display the videos' true blacks (they essentially just make those lighter).
[AT&T Samsung Galaxy Note I717] jjc5891:
This. The problem is in the kernel. To use ics, you need to upgrade your kernel and that's why everyone thinks it's the rom that's changing.

I'm pretty sure you can't flash a skyrocket kernel but the hardware is almost close enough that it might be possible
[AT&T Samsung Galaxy Note I717] schrochem:
So does the sidebar on Dolphin have a crosshatch background?

I don't have another phone atm to check

At the market they have a screen shot and it looks just like borijess' screen

Mine is definitely more splotchy and pretty damn hideous
[AT&T Samsung Galaxy Note I717] jpeg42:
As discussed here, the ICS leak made some changes to help with the clipping issues in some areas. You will notice this on the xda app splash page, market page, etc. borijess stated he is running ICS, you are on GB stock from what I can gather.
[AT&T Samsung Galaxy Note I717] tenderchkn:
I believe that the crosshatch thing that you describe is a result of miura, which is a hardware limitation of AMOLED screens. It's much better (and acceptable) on the Note. On the Skyrocket, the problem manifested itself with ugly vertical lines, which led me to return it.

The change in the drop off points is due to a simple contrast adjustment. Or even, just a black point adjustment. You simply tell the display driver to render anything below X as black. Several people have posted on this thread that using a screen adjuster app have allowed them to change the black point. This leads me to believe that Samsung tinkered with the contrast/black point in our ICS leak to cover up the problem, but left it alone in the Skyrocket leak, since they were less complaints about our problem with the Skyrocket.

What matters more is the brightness difference (contrast ratio) between true black, and one level above black. In GB, this level is "1". In the ICS leak, this level is "7". The contrast ratio between "0" and "1" on GB is the same as the ratio between "6" and 7" on ICS, which means that nothing actually changed. In fact, I'm sure that if we measured "1" on GB, and then "7" on ICS with a light meter, we would find that the light output is the same. This points to two possible causes: 1) a software problem caused by an incorrect gamma curve, or 2) a hardware problem caused by the display not being able to display dark grays properly.
[AT&T Samsung Galaxy Note I717] hyukki:
I'm fairly certain that the problem is software. The fact that you can use Screen Adjuster to change the contrast to make the phone display somewhat closely to what it's supposed to tells you everything. So the hardware can definitely handle grey.
[AT&T Samsung Galaxy Note I717] tenderchkn:
I don't think you understand what I'm saying. You can use software to adjust the black level - that is, you can force the display to no longer render black. To disprove my point, show me a software solution that allows you to darken the darkest gray. This will definitively prove that it is a software problem.

When true black is displayed on a certain pixel, that pixel is essentially off, which is why it appears so dark. However, when it is asked to display the darkest gray (RGB 1,1,1), it turns on, and becomes much brighter than black (RGB 0,0,0). Your Screen Adjuster solution basically forces all pixels to be on, and displaying dark gray instead of true black.

What I'm looking for, instead, is a solution that allows true black to be rendered, and dark grays to be darker. If it is the case that the display simply cannot render a darker color when a certain pixel is "on", then this would be definitively a hardware limitation.

EDIT: For clarification, "darkest gray" is defined as one level above true black, whatever that level is. As mentioned a couple of posts above, in GB, this level was "1". In the ICS leak, this level is "7".
[AT&T Samsung Galaxy Note I717] hyukki:
Okay, I understand your point. But maybe this will help us get somewhere.

I tried to replicate the problem on my desktop. I turned up the Gamma all the way and voila! It looks very similar to the test image shown on GB. Refer to DSC_5381. I have to tell you that I couldn't perfectly replicate what I was seeing on the screen but you should get the general idea. Number "1" was actually very much visible, unlike how it is shown on DSC_5381.

Anyways, in DSC_5385: with the gamma turned up, I tried moving the contrast up, which brought the cut off to around 7, which replicated ICS cutoff.

Then, as shown on DSC_5387, we can technically have a perfect screen if we turn down only the gamma values on GB, as this is the default values on my computer. Then we get a smooth transition, although the what is shown on DSC_5387 is a a bit darker than what I actually saw on the screen.

Now, I don't know if the same rules apply to phones or whatever and I know I could be TOTALLY wrong and totally missing the point but this is the best I could come up with. I'm not trying to prove you wrong or anything, just saying what I'm talking about could be a viable solution. So please don't take it the wrong way!

Cliffs: Just turn down the gamma values on GB to get smooth transition!
[AT&T Samsung Galaxy Note I717] hyukki:
On a second thought, you might have to adjust some other stuff in the process but turning down the gamma values seems like a good first step.
[AT&T Samsung Galaxy Note I717] tenderchkn:
Oh, I wasn't trying to argue with you at all. I just wanted to clarify my point, in case I wasn't being clear. I hope that it is as simple as bringing down the gamma curve too. But if it isn't possible to darken the level right above black (in other words, there are no intermediate levels), then we're looking at a hardware problem. Do you notice that even when you jack up the gamma curve on your monitor that it still gradually goes to black? That's because, at the hardware level, your monitor can display fine gradations between black and the darkest gray. On our phones, there is a big jump between black and the darkest gray. There has been no evidence, thus far, that this gap can be bridged by software. Therefore, I just wanted to warn you against the conclusion that this is definitely a software problem.
[AT&T Samsung Galaxy Note I717] hyukki:
Ah, I see. :D I'm still keeping my fingers crossed that this is a simple gamma problem. Only if I had some developing skills or at least know where the gamma values were... :(
[AT&T Samsung Galaxy Note I717] paleh0rse:
send a pm to supercurio and ask him how/where he found the values (and the same exact problem) on the n7000. ;)
[AT&T Samsung Galaxy Note I717] Spikestrip:
For what it's worth, I'll throw in my situation. On my SGH-i717 running the ICS leak that video looks perfect to me. I have the kind of vision where I can read the microprint on money that just looks like a line to most people. That said, if I go out of my way to find images with extremely dark areas transitioning into lighter ones I get some of the blockiness you all are talking about. As I understand it, this has to do with the pixels which are displaying true black being essentially off, and the darkest grey being on and thereby producing considerably more light especially considering what a Super AMOLED display is and how it works. And while I'm on the subject of OLED screens, the same blocky effect is visible on my PS Vita (in a very dark setting on completely black screens and very dark images) and I believe this to be just a trait of OLED screens and the way they produce the image we see.
[AT&T Samsung Galaxy Note I717] paleh0rse:
Unfortunately, the problem, whatever it stems from, is exponentially worse on the Note than on any other OLED device.

AT&T Forum Will Not Allow ANY Review that Mentions BLACK CRUSH!

I've already submitted my review twice. Used no foul language. I did not include any html links, just reported the issue about the problem and said to do a google search for "Samsung Galaxy Note BLACK CRUSH Demo". Both times my review was "rejected" for the following reason:

"Your opinion is very important to us and the ATT_mobile community. We appreciate you taking the time to write a review on Samsung Galaxy Note (TM) - Carbon Blue. Unfortunately your review did not meet our guidelines for posting on our site."

I guess AT&T and Samsung are VERY sensitive about this issue, and don't want the general public to have any prior warnings.

Perhaps it's time the news media broke this? That got the iPhone fixed in a jiffy.

[AT&T Samsung Galaxy Note I717] cgibsong002:
I really don't think there are any 'good' notes. just those mistakenly thinking so (just as i did and better pics revealed otherwise)
[AT&T Samsung Galaxy Note I717] Vcolassi:
Bingo! I've personally between me and my GF we have had 5 in hand personally. All same problem. One actually had a "screen" problem with really really jacked up black, anything and everything on the screen in black looked horrible.

2 friends have Notes with same problems. 4 I seen in AT&T had same problems, the 2 in Best buy had the same problems. You get the point. :)

It's something software related I believe. I own tonnns of Sammy products. Even my new 60" Samsung Smart 3D TV had "brightness pops" for the longest time. They finally acknowledged it recently with a firmware upgrade via a USB stick they mail to you. I'm sure this is a software problem too.

Still love Samsung but they seem to have little tidieous problems. The Note is just too awesome to skip because of this, for me at least. I only watch movies & Netflix on my 60" Samsung Tv anyway :D
[AT&T Samsung Galaxy Note I717] PeartFan40:
You all must have really bad luck. I just exchanged my Note at a corporate store (battery cover wouldn't snap tightly on one side, bulged out) and my screen is just fine. The first one was fine as well. Not sure if this matters, but mine is from China. Rev 0.3, SKU 65371. First Note was from Korea, can't recall Rev# though.
[AT&T Samsung Galaxy Note I717] PeartFan40:
My Note is just fine. Then again, I don't bother downloading specific tools that are designed to find the slightest flaw on a display. Not trying to be rude, bit I think you will find a flaw in anything, if you look hard enough. My 52" Sharp Aquos Quattron LED LCD TV has an amazing picture, but I'm sure if I look hard enough, I would most certainly find a flaw.

I'm a firm believer that 90% of this "black crush" issue is source related. People get mad at me for saying that. Not sure why.
[AT&T Samsung Galaxy Note I717] hyukki:
It's not a slight flaw. It is, in fact, a BIG flaw. It's not something you need a tool to notice for most people. In this case, about 80% of the people who voted said they are experiencing this problem. Of course people are going to get mad at you since you're disagreeing with the majority. If you disagree, you don't have to come back to this thread to prove others wrong, I'm sure they can think and decide for themselves.
[AT&T Samsung Galaxy Note I717] tenderchkn:
I'm a firm believer that 100% of your logic is irrational. The whole purpose of this thread is to prove beyond a shred of doubt that it is NOT a source problem. Since this has been proven, and you still come and claim that it's a source problem, maybe it's time to look into the mirror and check that ego.

And no, people don't come to this thread and realize that they have a problem. Most people have considerably better vision than you do, and see that they have a problem. They come to here to confirm what their eyes are already telling them.

Uh, no. This thread does not need to be closed. There still are people who want a fix and they have been trying to come up with a solution (somewhat). Everyone just needs to calm down and keep the thread on topic.
[AT&T Samsung Galaxy Note I717] Vcolassi:
To the person claiming they have a perfect Note. Take a screen shot of when you first open the XDA app and post it here. It's tricky as your task manager will pop up. With all my Notes I've had & friends Notes it has the same color distortion up top almost like layers of colors or a stain effect just on the top part. Where on my Galaxy Nexus it's one smooth brown all the way through. It does this on all 5 of the Notes ive had and others ive seen personally.

Or even easier just open your XDA app from the start and see if your device gets this same effect.
[AT&T Samsung Galaxy Note I717] hyukki:
This has been said multiple times before as well. You can not take a screenshot. You have to take an actual picture of the screen with a camera.

What's funny is that the splash screen doesn't have much banding and looks pretty smooth on ICS. But once I upload to to my computer, it looks horrible. lol.
[AT&T Samsung Galaxy Note I717] tenderchkn:
Because you're not in full screen. The brightness of the white on the rest of the screen causes your pupils to adjust to the white, and you're not able to see the difference in the dark colors. If you try covering up the rest of the screen with your hand, it will make a difference.
