Looks like I am going back to my GS2 I-777.

Its really dissapointing to own such a fantastic device. It has such a good cpu, data speed capabilities, battery life, to be held back by a software error. The screen easily has the capability of being one of the best ever produced.

I wish AT&T or Samsung would issue a statement and an eta for a fix. Why dissapoint current customers and lose potential future business over something that should have been resolved during testing?
[AT&T Samsung Galaxy Note I717] paleh0rse:
Neither company has even acknowledged that the problem exists.

Everyone who has called Samsung has been told that they're the first and only person to report the problem. Samsung, along with every major blog I have contacted, are ignoring it completely. :(
[AT&T Samsung Galaxy Note I717] DaKidSlim:
When using Vevo or youtube apps i notice this. When i go to Youtubes desktop site change the video to 720p and make it fullscreen i do not see the black crush or clipping.
[AT&T Samsung Galaxy Note I717] dcfella:
I've had 3 notes. The first one had pretty bad black crush. The second was much better, and only had slight black crush. I decided to get a white Note today, and just my luck, this one has horrible black crush. Any black backgrounds on youtube look like trash.
[AT&T Samsung Galaxy Note I717] jpeg42:
You had a winner and you traded it in!!??!! If you really wanted a white phone just buy a case lol :D
[AT&T Samsung Galaxy Note I717] dcfella:
Yeah now I'm kicking myself for exchanging it. I was hoping the black crush issue was less prominent in white notes...I guess not though. I put on a screen protector perfectly the first try too...sucks that I may have to return it again.
[AT&T Samsung Galaxy Note I717] JGuinan007:
Software issue?

How can this be a software issue if 80% of note have this problem and all run the same software? If it were a software issue wouldn't all notes have the same issue?:confused:
[AT&T Samsung Galaxy Note I717] jjc5891:
It might just be a calibration or tuning issue. There's a thread in another forum that people were using Screen Tuner (or something like that) on Samsung to fix color problems. I tried on mine but it wouldn't launch.
[AT&T Samsung Galaxy Note I717] borijess:
I think 100 percent have this issue to some extent. I have it but not as bad as others. I can watch Netflix at night without any problems. I do get the black crush but is not that bad compared to other notes.

[AT&T Samsung Galaxy Note I717] dcfella:
I agree with this. I've had 2 black notes, and 2 white notes(just got one today to replace my white note I got yesterday). Of the 4, the black crush was really bad on 2 of them, and just slightly noticeable on the other 2. My white note I got today is MUCH better than the one I had before. Using the Jay Z/Kayne West video and Moving Starfield youtube videos as reference on each device.
[AT&T Samsung Galaxy Note I717] borijess:
My white note looks good with those two vidoes but try the video rusty nails. The one with the swinging blanket. You can not hide the black crush in that video.

[AT&T Samsung Galaxy Note I717] JGuinan007:
Ok if 100% of Notes have the black crush and it is a software issue how come the extent of black crush/clipping varies between devices were one shows more clipping than another if the software is exactly the same on all devices?
[AT&T Samsung Galaxy Note I717] DaKidSlim:
Its an app related issue.. Go play the video through your browser in desktop mode... Change to 720p and fullscreen..... Huge difference
[AT&T Samsung Galaxy Note I717] borijess:
You don't believe it then return u r note. It just vary from device to device. Not one person has been able to prove their note is perfect. Hopefully a fix will be released. You can also use screen adjuster from the market and it will get rid of the crush. The only issue it lightens your blacks.

[AT&T Samsung Galaxy Note I717] flintdragon:
I noticed this first when attempting to take a very low light photo. I was testing the camera in a dim room and where the really dark sections are are all funky blocky looking. Areas around a light source look fine.
[AT&T Samsung Galaxy Note I717] paleh0rse:
that's exactly how I first discovered the issue -- dark photos of my black and white pets look like 8-bit Atari games when viewed on the phone, but the same files look perfectly fine when transfered and viewed on my PC. :(

Care to elaborate on which video you're talking about?

Sent from my Samsung Nizzote
[AT&T Samsung Galaxy Note I717] billzilla2000:
My Note has this effect and I've seen it on all other Notes I've used in stores.

I've done graphics for a living most of my life (a long time! heh) and I'm a bit anal when it comes to screens, video and pixel level details, including adjustments on the fly. My DLP video projector has a level auto adjust and I can see the changes during a film. Same with my Panasonic plasma TV. It shows up as a slight change in the black levels or overall brightness or contrast.

Anyway, I can see my Note doing this type of adjusting at times, but it doesn't happen in all apps, leading me to believe it's a selective software Gamma or Levels correction to boost colors and contrast. Ever notice watching YouTube that the screen border is JET black, no light at all? That's the effect I think Samsung was shooting for - total solid blacks with no visible light. That's why they designed either software or hardware display controller to render RGB value 0,0,0 to be null on the screen. The problem is that they didn't dial down the non-zero values to prevent crush. In Photoshop for example, you can adjust these levels with curves so there's no sharp dropoff.

Even if it's hardware determining that the difference between 0,0,0 is such a big jump to 1,1,1 (or 0,0,1 etc.) I think the evidence suggests that there's already SOME adjustment going on in software, so dimming down the lower values shouldn't be impossible or difficult. Of course it could require direct access to the screen controller which I don't know if all - or any - developers have.

One easy way to see how bad it is on your phone is to do a quick screen cap of the dialer when in a call and when you exit a call. On my Note, the green and red gradient (green = connected, red = ending, you have to be quick to grab the latter of the two) both show sharp drop to black at the bottom. Red has at least one color band error that shouldn't be there. When I emailed myself the pic, my calibrated monitor doesn't show the darker banding or sharp dropoff/crush (and the color looks different too).

If anyone has ever hacked their phone with Ubuntu or something and stripped out the OS, they could tell us whether the crush and banding is hardware. I have a feeling that there MIGHT be a systemwide gamma 'default' and that some apps call that function based on input from the light sensor, but don't quote me on that. Just a hunch. The up side is, that would mean a firmware update or kernel/root could fix it.
[AT&T Samsung Galaxy Note I717] paleh0rse:
that's exactly what supercurio has been digging into on the International Note, and he claims to have discovered the kernel-level issues related to how the kernel interacts with the hardware screen controller -- what he described as a "poor implementation by Samsung." He also stated that his fix for the N7000 requires ICS, so it's being held back until they get that.

I think we're going to have to get one of or best devs to reach out to him to get the pending fix ported over to our i717, or perhaps provide supercurio with an i717 of his own to port it over himself.

[AT&T Samsung Galaxy Note I717] dcfella:
Just watched it on my new replacement Note. Wasn't that much crush. I watched it in a dark room just now and was looking for the black crush. I saw it only in brief instances, but 95% of the video seemed fine to me.
[AT&T Samsung Galaxy Note I717] billzilla2000:
I think it bears noting (no pun intended) that some of these videos already have their own 'black crush'. I was looking at the Katy Perry ET video and I can see some pretty gnarly dropoff to black even on my PC running on YouTube at HD. The levels just above total black are pretty drab, too, giving a dull look to the dirt at the beginning around 00:00:20 thru :29 or so. There's a lot of 'noise' in the shadows, too.

Then again, some Netflix movies are looking pretty crushed in shadows, so it's definitely an issue, particularly with noir style anime.
[AT&T Samsung Galaxy Note I717] borijess:
Right the scene where there is a close up of the blanket always shows crush on any note. No matter how good your note is.

I'm Keeping my Note

I don't want to return my Note(although I tried to exchange). I'm just trying to understand how if it is a software issue how come the symtoms vary with different devices? If they are all running the same software they should all show the same level of clipping yet they do not. According to the poll why do most show all the numbers til 1 then drop to complete black and others show the drop from 4 down if it were the same software? It should be consistant across all devices running the same software to me anyway, unless people are lieing on the poll or did not perform the test correctly or it is not a software issue and there is somthing wrong with the displays themselves. I really don't know that much about the display or software for our device but if someone could explain this issue better I'd be happy to learn. Also I went back to Best Buy Mobile and Best Buy near me tested the displays and there stock to do an exchange and out of 15 notes all had the black crush/clipping and all showed #1 so I didn't exchang my Note (oh I really pissed off MGRs think I'm banned) Blue or white I could not find a good one or better one.
[AT&T Samsung Galaxy Note I717] cgibsong002:
ahh... now i see what we're talking about. I got the same thing on my computer watching the video though and my computer displayed the test image more or less correctly... soo not sure what that means.

edit:nvm. On my monitor i can see up to 4, so I guess technically I have moderate crush on here too.

on my note i can see all the numbers on the left and theyre all pretty much gray,

today i went to at&t to return a case i had bought so i figured id check out their display model with this image and wow...i could barely see number 10 and it didnt have color banding on the calc app where as mine has noticeable banding.

[AT&T Samsung Galaxy Note I717] tenderchkn:
Sorry, but I can't tell the difference in your "good" and "bad" photos. One's just misfocused. And the blocking in the video screenshot is from the video itself - I see it on my calibrated monitor. Don't use a heavily compressed video as an example.

I have said many times on this thread - the only objective test is the gamma test image. If you see all numbers, and a dramatic drop off to true black, then your display has black clipping, and will exhibit this symptom in everything. But please do not confuse the clipping issue with banding (which is a result of 16-bit rendering), and compression artifacts (which is a result of low quality video).
[AT&T Samsung Galaxy Note I717] Stay Frosty:
The first shot is a picture of the phone taken by a camera, which means that any screen defects are also captured, and hence visible on your computer monitor. The second shot is a screenshot taken by the phone which represents the actual image as stored in the video memory of the phone. That's what it should look like in a perfect world with perfect screens.
[AT&T Samsung Galaxy Note I717] Scythe024:
Black clipping is extremely bad when I put my finger on the lock screen before unlocking. Is there any way to take a pic of lock screen with my finger on it? Without using a different camera obviously
[AT&T Samsung Galaxy Note I717] Scythe024:
It won't let me use full size
[AT&T Samsung Galaxy Note I717] jezza333:
I took the [bad] shots with a Logitech webcam as I don't have a dedicated camera. I have to say this regarding compression: you are wrong. Very wrong. I have had NO issues on my Galaxy Tab 7.7 when playing the same file and my previous Note had no clipping, but did have banding which has now been fixed with ICS.

There's also green shading in dark scenes, as some have mentioned. I've also tried watching 1080p encodes with over 10Mbit bitrate and again, the same issues are encountered.

There are thousands of people with this issue. It's not what we're playing. It's the device or some low level driver/setting that isn't modified with firmware flashing.
[AT&T Samsung Galaxy Note I717] Talderon:
I used this app: https://play.google.com/store/apps/details?id=com.netmanslab.sa

Turned down the brightness and things look a TON better in regards to the clipping.

I'm still sticking with my guns that this is a software issue, not hardware.

Thanks!
[AT&T Samsung Galaxy Note I717] baudilus:
Looks fine on my screen, just overly dim (dimmer than it looks on my laptop screen). I can see the 10 9 and 8, and if I look really hard I can see the 7.

EDIT: Just looked again - i can see about four distinct shades in the image, so I guess I have minor crush.

EDIT AGAIN: I downloaded the image to my SD card [instead of looking at an ostensibly compressed preview from Dropbox], I turned the screen brightness all the way up, and turned off "Auto Adjust Screen Power" and the image looks as good as the image on my laptop screen - I can see distinct differences in the shades of gray on nearly every number, plus I can make out every number except number 1.

So I guess I'm back to being fine.

[AT&T Samsung Galaxy Note I717] tenderchkn:
If you can see every number, it means you're not fine. "Fine" is having a smooth fade to black, and not being able to see a distinct change from gray to black.
[AT&T Samsung Galaxy Note I717] tenderchkn:
I wasn't arguing with you about the fact that the issue exists. I know for a fact that it does - I started this thread. I was just commenting that your screenshots are not the best way to demonstrate the issue. I see large black blocks in your video screenshot, which is an indication of low resolution and/or highly compressed video. By the way, Apple ProRes 422 (HQ) has a target bitrate of 220Mbps for 1080p video, and raw uncompressed 1080p video is over 1Gbps, which means your 10Mbps video is compressed more than 99% and has compression artifacts too.

My point is that video screenshots is a poor way of showing the problem. Just shoot a picture of your phone with the test image. If clipping shows there, then it will manifest itself in everything else.
[AT&T Samsung Galaxy Note I717] knokstudios:
Doing a screen capture ont prove anything. It will only show what the image is intended to look like. you have to physically take a picture of the phone showing the image, but then its still not entirely accurate. only tru way is to do it yourself and look at it with your naked eye.

[AT&T Samsung Galaxy Note I717] sprecker:
I personally think that the pic from the OP is just a crap test. There are much better tests that actually show results. Plus, IMHO, a test used to show the black levels of a LCD with a contrast of 1000:1 would look way different on an SAMOLED with it's higher contrast ratio. Try a real black level test used to actually show full spectrum black levels and see how it looks.

Just want to chime in that a good display will show all of the numbers.

I have a 10-bit S-IPS panel (that's 1.07 billion colors) and all of the numbers are visible. Barely so at the lower end of the spectrum but visible nonetheless.
[AT&T Samsung Galaxy Note I717] JGuinan007:
So does that also mean you get grey blocks on your screen when you are trying to watch HD movies or black wallpapers have blocking on them as well?
[AT&T Samsung Galaxy Note I717] tenderchkn:
None of your amazing test images show anything more than my "crap" test. RGB 1,1,1 should be display as indistinguishable from black (RGB 0,0,0) no matter what the contrast ratio is. If your test images display "fine" on your phone, does box #1 in the first test image distinguishable from the background, which is pure black? If so, then it's not normal. If it is not distinguishable, then take a correctly exposed photo of your phone in a dark room and prove it. You can also try image #2 and the 1% box.

Speaking of crap tests - images 3 and 4 use a compressed RGB range of 16-235, instead of the full 0-255 range. Use Photoshop or another image editing software to verify that every strip until "18" is RGB 0,0,0. So of course, every strip up until 18 will display as black and therefore show no problem. I'm confused as to why you didn't verify this yourself, as you're such an expert on this matter.

You obviously have no idea what you are talking about, so please refrain from spreading misinformation.

Yeah, the operative word is "barely". I have an 8-bit S-PVA monitor and I can see all of the numbers under the correct conditions (pitch black room, black background against the test image, and squinting my eyes an inch from the display). Unless you have a FirePro or Quadros video card, your GPU only outputs 8-bit channels, so there's no need for a pissing contest to show off how many colors your monitor can display, since it wouldn't display them anyway without a previously mentioned video card.

The point is not that you are able to see each tone. The point is that on a correct display, there should not be such a distinct difference between 0 and 1.
