[AT&T Samsung Galaxy Note I717] paleh0rse:
Unfortunately, at least with the first leak, all they did was adjust the system-wide contrast in what looks like an attempt to hide the issue By adjusting the contrast, they just made all deep blacks look more grey and shifted the clipping to between 6 and 7.

You can make the clipping in the ICS roms look identical to the old GB clipping (IOW, between 0 and 1 in the gamma test) by simply using any screen app to set the contrast -15. :(

Maybe we'll get lucky with the next leak...
[AT&T Samsung Galaxy Note I717] DekkonBlack:
I use 2x battery screen filter and set the color from black to white then set opacity to 90 for regular 80pct for video and no more black crush
[AT&T Samsung Galaxy Note I717] DesignGrits:
Hows mine looking? Looks fine to me on the phone, but on here is looks like there are green squares. Funny, this looks nothing like what I see on my phone.
[AT&T Samsung Galaxy Note I717] paleh0rse:
Is that a photo, or is it a screenshot?

Screenshots don't capture what you're actually seeing on your screen. You need to use a separate camera to take a photo of your Note displaying the test image...
[AT&T Samsung Galaxy Note I717] DesignGrits:
screenshot
[AT&T Samsung Galaxy Note I717] paleh0rse:
in order for us to assess your display, you'll need to take a photo of it.
[AT&T Samsung Galaxy Note I717] schrochem:
Good one!

This works quite well. While not a complete fix it gets rid of the splotchiness and has a better gradient.

DekkonBlack...try R97 G97 B97 at 94% transparency. That will give you a better gradient and deeper blacks.

Here's what the pic looks like. this is Quick Pic but it looks the same in gallery.
[AT&T Samsung Galaxy Note I717] paleh0rse:
The gradient in that photo looks horrible. Was that taken AFTER you made the adjustments?

The clipping is quite clearly still there between 0 and 1, and the blocks on the entire left side (1 to 10) are wayyyyy too bright.

On a proper display, the left side won't have much grey at all -- IOW, 10 down to 1 should be MUCH darker blacks, with true black at 0.

It looks like the app you used, or the camera, actually made the greyscale even worse, not better... :(
[AT&T Samsung Galaxy Note I717] jpg71:
Just a thought - the image may be overexposed. I went through this exercise myself when trying to understand what you guys were talking about. The pictures I took of my phone looked nothing like what they were to the naked eye. I see almost nothing on the left hand side of the test image in Quickpic, but as soon as I go to a dark room and take a picture of it, the overexposure makes the right side look all bright and you can see pretty much everything down to 1.
[AT&T Samsung Galaxy Note I717] paleh0rse:
Yeah, you may be right... at least, I hope so! lol
[AT&T Samsung Galaxy Note I717] schrochem:
yea exposures tricky....it does look darker than that.

Also, I don't really care what the 20 step looks like...its the real world stuff that matter. I went and watched that glee youtube and the splotchiness went away, much better. So it's definitely better than anything I've seen suggested so far....
[AT&T Samsung Galaxy Note I717] borijess:
Has anyone on ICS tried screen filter to try to temporary fix for black crush?

Sent from the TermiNOTEr! ;)
[AT&T Samsung Galaxy Note I717] paleh0rse:
What was the name of the app?
[AT&T Samsung Galaxy Note I717] tyshemi:
What app did you use to fix this?
[AT&T Samsung Galaxy Note I717] paleh0rse:
Nothing actually fixes it yet, but some screen adjuster apps make it slightly better.
[AT&T Samsung Galaxy Note I717] tyshemi:
do you recommend one ? or leave it be ? mine comes and goes and let me tell you my buddy is a att supervisor so i showed him and we tested over 6 drvices all the same im glad because im still thinking its software!
[AT&T Samsung Galaxy Note I717] schrochem:
I had the app already because it does just what I need to regulate my data connection and save battery.

Its called 2x battery

I didn't even know it had that setting til that poster mentioned it. I'm not sure if its in the free version.

I'd be interested in what others see. Post another video and I can check it I suppose.
[AT&T Samsung Galaxy Note I717] jjc5891:
I don't like apps that mess with the screen anymore. They tend to use more battery than they save via lower display brightness and seem to slow the phone down. An example is screen adjuster...run a quadrant test with it on and then off and look at the FPS and 2D/3D scores and you'll see what I mean.

No application is know to fix the issue (yet).
[AT&T Samsung Galaxy Note I717] jjc5891:
Using ICS and the AOSP gallery, the test image displays perfectly just like quickpic. The samsung gallery has a dropoff to black at 7. Looks like it's software guys...

[AT&T Samsung Galaxy Note I717] iNTER5LOve:
Just download (sceen Adjuster) from play store

and put red (3) contrast (10 - 20)

and check picture again
[AT&T Samsung Galaxy Note I717] sag7392:
Using this apps makes the crush a lot less noticeable. What's a good setting...besides the one you gave...to adjust to tone down the red?

Thanks!
[AT&T Samsung Galaxy Note I717] dvd7000:
I've tried this app and it does lessen the black crush effect. However, it also turns

all

blacks to a dark gray.

A temporary band aid at best until a proper fix is found.
[AT&T Samsung Galaxy Note I717] sag7392:
After playing with the settings for a little while, I noticed this as well. I found that setting contrast to -2, works best without graying the blacks too much on my Note. Does seem to help.
[AT&T Samsung Galaxy Note I717] Bataga:
Yup just noticed using alpha ll.
[AT&T Samsung Galaxy Note I717] dvd7000:
Hardware or Software Problem?

My 30 day return privilege for my Note will expire on 5/8/12. Does anyone know with certainty whether the black crush problem is caused by the software or the hardware?

If I wait for ICS, and it doesn't fix it, I'm stuck with the problem until I'm eligible the next phone upgrade in another 2 years.
[AT&T Samsung Galaxy Note I717] Scythe024:
current ICS leak does not fix it, to be honest i doubt it will be fixed in the OTA update as well. It does seem to be a software issue
[AT&T Samsung Galaxy Note I717] PaulF8080:
I'm beginning to wonder what you are seeing. The picture shows raw colors. If you are comparing to your gamma adjusted PC display, aren't you comparing apples to oranges? When I look at the picture I see that they removed the 0,0,0 color so block 0 looks like an uncorrected 1,1,1. I see no clipping between blocks 0 and 1 in that pic. Also, the "gamma" test goes: block 0 is 0,0,0 block 1 is 9,9,9 block 2 is 18.18,18 etc. So part of the big 0 to 1 transition is caused by the image. I wrote a perl script to show all 256 colors in a 16x16 grid. The 0 to 1 is smaller at 0,0,0 to 1,1,1. My Quickpic now looks like the picture after it was upgraded. I am getting very confused now because I am shooting at a moving target.
[AT&T Samsung Galaxy Note I717] tenderchkn:
Doesn't matter. You can try whatever brightness setting you want. It won't affect whether it shows black clipping or not.
[AT&T Samsung Galaxy Note I717] paleh0rse:
I have reported this issue to Samsung itself, Engadget, Android Police, Phandroid, and quite a few others -- yet NONE of those entities have even acknowledged the problem.

I have also been asking everyone to report the issue to the same blogs and media outlets. PLEASE DO SO!!! :)

When I voted I had not done the test right, after reading all the post and trying different things I see what you guys are talking about. I don't think I will return the phone because of this. Maybe it can be adjusted thru software / lighting enhancements :)
[AT&T Samsung Galaxy Note I717] paleh0rse:
The browser does the same thing with most youtube videos, but they all end up with washed out grays instead of blacks.
[AT&T Samsung Galaxy Note I717] JGuinan007:
Samsung said I'm the only one reporting this issue

I talked with someone at Samsund today after I ran this test and he said this was the 1st time it's been reported I thought this was also an issue on the N7000 and was reported? I guess Samsung doesn't think there is a problem with this.:confused:
[AT&T Samsung Galaxy Note I717] paleh0rse:
The Samsung rep straight-up lied to you. They have said the same to each and every person who has reported the issue, including me.

I'm seriously considering sending a blast message out to every major media outlet in the country, but I'm not sure exactly how to do that... lol

Once proven, if done correctly, this kind of thing could really harm their sales if they fail to address it in a timely fashion.

The fact that the problem occurs with popular services like Netflix might be the way to gain reaction, but it's extremely difficult to demonstrate that fact on a mass scale...??
[AT&T Samsung Galaxy Note I717] jpg71:
Sorry for the poor quality, but I think it at least shows I have more of a gradual gradient type of screen situation. My first Note had a screen similar to the OP's.
[AT&T Samsung Galaxy Note I717] tenderchkn:
Even from that photo, I can see all the way down to one, and the drop-off at zero.. I overexposed my photo for the sake of visibility. If you're able to see the 1, and there is a significant drop-off to black, then your phone has the clipping problem. Obviously, we can't make an objective conclusion about how gradual the gradient is, as we would need to compare two phones side by side to make that judgment.

I am more than willing to help in any way that I can. I have called Samsung, and went to an AT&T store and demonstrated the problem live to a rep. Supposedly, he has forwarded all my documentation to their Samsung rep, and is waiting to hear back. I don't expect much from this, of course.

When i have some free time i will post a pic but it looks like the guy just above with the white note (which i notice is being picked apart now too)

I can definitely see why I have had such a hard time understanding the issue when discussing it with palehorse in the other threads.

Mine doesnt seem to have the issue/or at least not as bad as others.

As i mentioned in the other thread... Any clip or pic that I have seen clipping/crush on I have played on other devices and seen that same clipping and crush on those exact spots on those devices
[AT&T Samsung Galaxy Note I717] paleh0rse:
Your skyrocket photo actually looks better on the left side than any photo I've seen of a Note so far. I'm looking forward to seeing an actual picture of your Note.
[AT&T Samsung Galaxy Note I717] tenderchkn:
I do happen to have two Notes that I can take a photo of side by side. One is slightly darker and more pink than the other, so yes, there is slight variation from copy to copy. But, no, they do not vary enough that one shows more clipping than the other. They both suffer the same problem.

I don't have a dark room to take a photo right now, but I will get that done tonight.
[AT&T Samsung Galaxy Note I717] jjc5891:

[AT&T Samsung Galaxy Note I717] jpg71:
Those of you that are seeing severe black crush (all of the numbers are clearly visible with a sharp contrast drop between 0 and 1), what does this pattern test look like? Are all the levels distinguishable or is the first (maybe even second) row all lit the same?

Edit: perhaps a link directly to the PNG might be better:

[AT&T Samsung Galaxy Note I717] tenderchkn:
If you're going the test correctly, i.e. viewing the test image in full screen in QuickPic in a DARK room, then your Note is miraculously displaying blacks correctly. If so, please post a photo of your phone displaying the test image.

Otherwise, please run the test again, under the conditions that I have outlined in the first post.

For me, all levels are distinguishable (as documented by the photo that I posted in the OP. If you mean the test image you linked, it's very hard to distinguish the first and second row, since the boxes are not right next to each other. But that's the way it's supposed to be, as the differences from one gray tone to the next is very small. But I can tell that it gradually gets brighter from 1 to 10 (first and second row). And there is a major contrast from box 1, to the background (pure black).

[AT&T Samsung Galaxy Note I717] paleh0rse:
the problem is that we still don't know whether or not his N7000 (International) fix will also work with the i717 (AT&T)... and he's not responding to our posts asking that question. :(
[AT&T Samsung Galaxy Note I717] jjc5891:
The better question is...why isn't Samsung fixing this?
[AT&T Samsung Galaxy Note I717] tenderchkn:
+1. Hopefully, it is possible to port it. Even so, ICS is at least 3 months away, and a port is another 3 months? That's a lifetime and a half for phones. Not that I don't have any patience, but one of my main reasons for getting the phone is using it as a media player. This makes watching movies at night all but unbearable.

If I had a venture a guess, it would be that this is something that well over 99% of users would not notice unless it is pointed out to them. And Samsung can easily deny the existence of a problem to the handful of people who do complain. Recall what it took for Toyota to acknowledge that there was a problem with sticking accelerators in their cars. And this was a matter of life and death. Compared to this, Samsung can more or less tell us to go screw ourselves, and no one would blink an eye.
[AT&T Samsung Galaxy Note I717] jjc5891:
Think of it from a business perspective though...if it's as easy as a software fix, how much would it take a developer to fix this, maybe 4 weeks max to find the problem, fix it and test it, so 160 hours x $150/hr (being generous) = $24,000. Now what's easier to fix, a $24,000 bug or bad PR for you entire line of AMOLED phones?
[AT&T Samsung Galaxy Note I717] Scythe024:

Still not a single photo of a Note that doesn't have this clipping issue...?
[AT&T Samsung Galaxy Note I717] tenderchkn:
You have a very valid point in theory, but in practice, I don't see much that we can do in terms of generating the amount of negative PR that will make Samsung pay attention. Using my Toyota example, they simply denied the problem for years. When they were finally investigated, they paid a fine that amounted to a slap on the wrist. There was a TREMENDOUS amount of bad PR, but in the end, that did not affect sales, and now, it's all but forgotten. If it took that much to get people to care about having a car that doesn't accelerate on its own, what do you think it might take for people to get angry about such a minute problem like getting your phone to display black correctly?

The goal of this thread is to 1) make Note owners aware of this issue, and 2) have a simple and objective way of identifying and demonstrating the problem. If it turns out that we make enough people aware, and we're able to make enough noise, and get an solution one way or another, then great. But it might be a long shot to hope that Samsung will officially acknowledge and respond to the problem, based on this and the several other threads regarding this on XDA. We're going to have a make a LOT more noise.

It maybe an easy fix for us AT&T Galaxy Note users. The AT&T Galaxy S2 Skyrocket has the same adreno 220 GPU but doesn't suffer from black clipping as we do.

Perhaps a dev could rebuilt a Note rom using the Skyrocket GPU driver.

Edit:

Possibly even rebuild the Note's GPU driver using the color calibration settings from the Skyrocket or even the captivate as it has a pentile screen.

If a trusted dev could build a test rom I am willing to flash it.
