Thank you for posting that! My only concern, now, is that your total lack of clipping may indicate that this is definitely a hardware issue.

How long did the exchange with Samsung take? I may try to do the same...
[AT&T Samsung Galaxy Note I717] jjc5891:
If this does turn out to be a hardware issue, is this something we can get fixed under warranty? I'm past my 30-day exchange, so if I'm stuck with a junk phone while the new ones are coming out OK, I'm going to be pretty pissed.

Almost wondering if some sort of class-action lawsuit is possible...
[AT&T Samsung Galaxy Note I717] SweetRedVoice:
I got the black note as an early upgrade pre-order. I returned it within the 30 days and got a "no questions asked" refund. Although with the help of XDA I found ways to fix most of my little issues. I felt I had lemon. Had, lots of lag, poor battery life, unit running hot and of course the black clipping.

I missed the note so much that after a week I decided to repurchase a white one and take a chance. I ordered online on Thursday and got it today. They are like Night and day! 100% better!

I charged it to 100% and have had the screen on s(etting up stuff) for almost 2 hours and Battery at 90%!

Best of all no clipping in any of the netfix, YouTube, or gammatest files posted in this thead.

I do not know if this is hardware or software related. But I do know My current Note is not effected.

I ordered my (black) AT&T Note from Amazon wireless and just got it on Friday, and mine has the black crush issue in spades, though none of the other problems you talked about, other than having to go to the Corporate store to get the phone# port to work.

I'm a sad Panda. :(
[AT&T Samsung Galaxy Note I717] tenderchkn:
Is it just me, or is there clipping at 7? 8 looks like it is discernible, and then there's a big drop off to black at 7. See attachment - I marked the line in the top photo, and the bottom one is original. SweetRedVoice - does it actually do this, or is it just the photo?

If it actually does this, then the only thing that is different is that the black point has been moved, but the underlying clipping issue is still present.
[AT&T Samsung Galaxy Note I717] tyler79durdan:
I see all the numbers as the op. I do not see lower than twelve on my tablet... Maybe it's a byproduct of the capacitive layer and or manufacturing process.. i.e. super amoled
[AT&T Samsung Galaxy Note I717] knight4led:
So fill me in here. Has anyone attempted to track whether the Black Crush is more pronounced on Chinese or Korean notes? Also do we know if one of the colors is having more issues than the other?

I ask because I was planning to upgrade later this month.

Its the photo. the transition/graduation is very smooth on both sides. In a dark room I can only see numbers 17-21 very faintly. Photo was taken in a lightened room without the flash so that I could show image.

[AT&T Samsung Galaxy Note I717] tenderchkn:
Thanks for your feedback. Maybe the Made in China phones don't exhibit the problem.

However, it's hard to believe you when you say that you can only see up to 17, because in your photo, I can definitely see the entire right side, and and three boxes on the left side (I'm viewing this on my calibrated monitor, not my phone). At 7, there seems to be an abrupt drop to black. If I can see this in the photo, it would seem that you should be able to see the numbers in a dark room. Can you retry this at night with the lights off? Turn the brightness to full, and see what the smallest number you are able to see is. Seeing it barely still counts.

Also, if possible, can you take a better photo of the screen? I realize that it's difficult to capture it in a dark environment without a good camera and/or tripod, but a dark setting is necessary to document this properly. Otherwise, the ambient light overpowers the display. A couple of things that would help is turning the brightness to the max, and setting both the camera and the phone down on a level surface, and taking a long exposure.

Your efforts will definitely be appreciated. Hopefully, we can get evidence that the Chinese made phones do not have this problem, and we can start pressuring AT&T or Samsung to replace our phones with Chinese made ones.

MIC, pix, enjoy

You know I was looking at this and I think the MIC I got has it as well. The MIK I had was manufacturered 02/06/2012, not sure of the date on the MIC. But I got it brand new delivered overnight from AT&T 03/30/2012.

I use a 000 black wallpaper and when I press the unlock animation shows, the black transformes/shows gray/black bands. Not sure if that is what is meant by "banding".

I tested your image, but quickpic seems to have updated and the settings are slightly different, regardless I see all the numbers from 1+, 0 being totally black and doesn't transition in a darkroom, but it does in a lit room. I have to tilt the phone to notice the numbers if viewing close, but if at arms length it transitions gradually.

EDIT: You know I also notice a few settings and options that are default are slightly different on my MIC than my MIK.
[AT&T Samsung Galaxy Note I717] schrochem:
Made in korea......

It is gradual and a bit darker than the pic but....

Tenderchkn [OP]

I am comparing my new note (Rev0.3 Made in China) with a very faulty black note (Made in Korea)

I downloaded gammatest image and opened it in QuickPic per instructions.

My observations where of the image in a room with natural light (not bright but not unlit). with my previous note I could see all the numbers clearly With a big jump 0-1. With the new note I see clear graduation of the colors which looks right to me. 0-7 is very dark, can bearly see numbers. 7-21 I can see all numbers.

I will upload a picture taken with my skyrocket (photography is not my strong point) in an unlit room and full brightness on screen when I get home.

Ya know you beat me to it. Your explanation is so much better than mine. Your images look like my Note. I am not sure if this still constitutes clipping or just a lesser version of it. So I guess my new note has clipping too :(

Although the blacks are definitely blacker than my previous note and I can now enjoy netflex and youtube which where unwatchable on my previous note.

Wow, all I can say is...you lucky bastard! Don't ever trade in that phone. It's too bad to hear that not all MIC phones are good like yours.
[AT&T Samsung Galaxy Note I717] SweetRedVoice:
I am very happy to finally have a fully functional phone! This is my first time as an early adopter. This device has so much potential. I was so disappointed that QA was not better. It really shouldnt take all this for a device to operate as advertised.

Let me know specifics if you want me to check any other settings that may help pin this issue down.

FYI, my device is completely stock (not rooted) and no side loaded apps.

I updated to the leaked ICS posted tonight and I went from seeing 1+ to now I can see 7+ but black clipping is still very much present in images and videos. Thought I would let everyone know that it did have an effect which means that software mods can definitely alter it.
[AT&T Samsung Galaxy Note I717] clockcycle:
Oh ****!

Ok I went into Quickpic > Settings > Cache.

There I checked "HD fullscreen previews" and cleared both cache. I look at the test image again and it totally changed and transitions perfectly! Don't know if this did anything or has anything to do with anything. Only other thing was I set brightness to max, but in a lit room.

I can still see all the numbers 1+ but it transitions slightly, in a dark room.

I tend to think it has something to do with the ambient lighting sensor as well.

Lol!! I took 10 pictures and on none of them you could see anything :(.

I do watch Anime on both the MIK and MIC and they tend to look as they look on my notebook. At least in a lit room, I don't tend to do much with my phone in the dark.

EDIT: phone is @mashi_root...
[AT&T Samsung Galaxy Note I717] cgibsong002:
Huh? Look at image 2. I can see up to five. I'd call that moderate crush.
[AT&T Samsung Galaxy Note I717] tenderchkn:
It's less about where you can see up to, and more about how smoothly it goes to black. Or more technically, the contrast ratio between black, and one level above black. On most of our phones, black is very dark, and one level above black is very bright (probably in the magnitude of 100 times brighter than black). If this difference is smaller, then we wouldn't notice the transition and therefore, the clipping would be invisible or nearly so.

Obviously, it's not a perfect picture but I can only go off of what I see, and it looks different than my phone or pictures of other phones posted on this thread.
[AT&T Samsung Galaxy Note I717] borijess:
Has anyone tried to see if the black clipping or crush is fixed? With the new ICS update.

Sent from the TermiNOTEr! ;)
[AT&T Samsung Galaxy Note I717] jasonrush:
Its still there on the leak. With the picture i can only see 7+ but the transitions are hardly noticeable.
[AT&T Samsung Galaxy Note I717] tenderchkn:
Just flashed ICS. There is a change, but black clipping is not fixed. Instead of seeing to 1, I can only see to 7 (as reported above). After this, it clips. Basically, the black point moved, but there is still an abrupt drop to black. In practice, this will help mask much of the problem in videos, as RGB 6,6,6 and below will be displayed as black, but doesn't solve the underlying problem itself.
[AT&T Samsung Galaxy Note I717] SweetRedVoice:
It is difficult to capture in a photo. I do not have professional photo equipment. (Or decent camera)

When I look at the gammatest image with my Mac and new note on full brightness. I can see a smooth, consistant transition in the colors, 0 being black, 1 a little less black than 0, 2 a little less black than 1 etc. This looks right to me.

With my old note 0 was black, 1 was dark grey, 2 was a little less grey than 1 etc.

IMHO I think the visibility of the numbers is subjective as it depends on your back light, the room light and the angle you view your screen. I think it is more notable to see a smooth transition in the shades of grey, not big noticeable jumps (clipping) as OP pointed out.

I am by no means an expert. I am just trying to help pin this issue down and explain what I see for whatever its worth to those that care.

[AT&T Samsung Galaxy Note I717] Scythe024:
so just installed ICS and tried the first test again. Went from seeing all the numbers to not being able to see anything lower then 7 which i hope confirms a software issue
[AT&T Samsung Galaxy Note I717] 00mred00:
Definitely see an improvement.

The amy van burn video is still pretty bad. they black crush is almost completely gone from the Swedish house video
[AT&T Samsung Galaxy Note I717] TonyBigs:
This reminds me of the early days of testing upconverting DVD players and digital video. The manufacturers would mess up and not output the correct luminosity for video or color space for HD.

In *digital* 0-255 is the range of luminosity. In *video*, the range of luminosity is 16-235 (that is, blacker than black and whiter than white can exist). If the mastering of the video or the playback expands 16-235 into 1-255, black will be crushed because the *video* black (16) is being forced to 1, 17 to 2, 18 to 3 and so forth. That is visible black or dark gray is forced into the sub-black. Conversely, forcing 1-255 into 16-235 results in a washed out, lifeless picture because sub black (1) is being forced into visible (16).

It's amazing we're still having these problems all these years later.
[AT&T Samsung Galaxy Note I717] borijess:
Ok installed ICS and I could still see down to 1 but video playback has been improved. The starfield video looks almost perfect and the blanket video is improved. I still see black crush in this video but not as bad. I think what helps is the FPS is alot higher in ICS.

Update: Netflix looks incredible now no black crush at all!! VERY HAPPY!!
[AT&T Samsung Galaxy Note I717] jjc5891:
I reported this in my bug thread but with the ICS leak, the videos are definately improved HOWEVER the clipping still exists in the test images.

On GB I saw the 1 block and an abrupt drop to black

On ICS I see the 7 block and an abrupt drop to black
[AT&T Samsung Galaxy Note I717] Sinful Animosity:
I could only see down to 11 with ICS.
[AT&T Samsung Galaxy Note I717] schrochem:
FYI, when comparing against a tbolt and a sensation yesterday I could see down to 7. I'd say that part is perhaps 'normal' but the gradient may be different.
[AT&T Samsung Galaxy Note I717] tenderchkn:
Thanks, but we're experience a different problem from what you are describing. The problem is not caused by 16-235 color range in video. It is caused by the display (either a hardware fault, or an incorrect gamma curve). In the test picture that I posted, box 1 is RGB 1,1,1. But our display makes it look like RGB 16,16,16.

I assumed that it was a problem with the color range initially too, as you did. But then I noticed the black clipping, and realized that true black displays correctly, but dark grays display way too bright. In the ICS leak, it was addressed by simply moving the black point from RGB 0,0,0 to RGB 6,6,6. But they didn't fix the actual clipping problem, as many have noted above.
[AT&T Samsung Galaxy Note I717] jjc5891:
I was messing around with screen adjuster, and i noticed that if I set contrast to -15 and look at the test image its exactly the same as before. Seems like samsung tried to pull as fast one on us by adjusting the contrast to mask the problem
[AT&T Samsung Galaxy Note I717] jpeg42:
Honestly, if that is all they did, I think I am OK with it. It is much more tolerable now and the crush/clipping in videos is hardly noticeable with any ambient light now.
[AT&T Samsung Galaxy Note I717] jjc5891:
The problem now is that some of your greys are now going to be pure black. There will still be clipping but it will be in the grey parts of images/videos, not the blacks.
[AT&T Samsung Galaxy Note I717] tenderchkn:
You didn't really expect a real fix, did you? Still, if it is just a contrast adjustment that actually crushes grays into blacks, then I'm disappointed.
[AT&T Samsung Galaxy Note I717] jpeg42:
Yup you are correct after some usage. Bummer.
[AT&T Samsung Galaxy Note I717] PeartFan40:
The Note is a great phone, with an amazing display, and great specs. All phones suffer from this incredibly minor issue. Why all the fuss?
[AT&T Samsung Galaxy Note I717] tenderchkn:
The only phone that I know of which suffers from this issue is the Note. Read the rest of the thread - there are plenty of people who report that other phones are fine (including ones with AMOLED screens). Also, you would find that there are many of us who don't consider this to be a minor issue at all. Since this is supposed to be an "amazing display" with media consumption as one of the phone's primary intended uses, this issue is especially pronounced.
[AT&T Samsung Galaxy Note I717] esincho:
I never had a phone do this
[AT&T Samsung Galaxy Note I717] Sinful Animosity:
Happens on the skyrocket. Even happens on the Atrix to an extent. I really don't see the big deal but if this is really that much of a deal breaker I suggest you return the phone. Almost all phones have a problem with the screen.
[AT&T Samsung Galaxy Note I717] Reclaim:
I've never had this problem on a non Samsung phone. I like the Note a lot, but let's face it and be real with ourselves. Super amoled screens are overrated.
[AT&T Samsung Galaxy Note I717] Teseract666:
Well, I noticed on Amazon (where a lot of people buy the International version or buy from Amazon Wireless for the AT&T version) that there were no reviews covering this issue, so I posted one and also added an image showing the gamma results:

http://www.amazon.com/gp/customer-m...HQL30/ref=cm_ciu_pdp_images_0?ie=UTF8&index=0

It won't let me attach the image to the Amazon Wireless listing though, just the N7000.

At least this way people will be aware of what they may be getting in to, though they removed the links I inserted of course, bleah.
[AT&T Samsung Galaxy Note I717] PeartFan40:
This "black crush" problem is a resilt of poor video/picture quality. It's not a flaw of the device. I have seen this occur on my SGS II, my Skyrocket, and my Note. I've also experienced this on my 28" $600 computer monitor, and even on my 52" Sharp Aquos Quattron LED LCD TV. It's a source issue, period. Of the resolution of a particular video is low, or of poornquality, pixelation or blockiness will occur. Its completely normal, and affects all types of displays. It's not unique to the Galaxy Note. Threads like this annoy me to no end. It's pretty simple, avoid low quality video and images and you won't see it. This isn't rocket science.

Here is a link to a forum where certain blu-ray movies cause this.

Please, stop creating these ridiculous threads. All it does is create panic amoung Galaxy Note owners.

Not trying to be rude, but seriously...The display and the rest of the hardware on the Note is perfectly fine. Actually, the Note has the best looking display I've seen on any mobile phone thus far.
[AT&T Samsung Galaxy Note I717] Teseract666:
So if a source looks fine on my old 4.3" phone, looks fine on my 17" monitor at work, looks fine on my 22" monitor at home, and looks fine on my 65" 1080p TV set at home via HDMI out on my HTPC, but looks like crap on my 5.3" cell phone, it's a source issue and not the 5.3" cell phone?

I'm sorry, but if it looks good on a 65" 1080p screen but looks like crap on a 5.3" screen, it's not a source problem.
[AT&T Samsung Galaxy Note I717] PeartFan40:
I see it on my phone, TV, monitor. Its 100%a a source issue. Some devices will show it more than others, but it doesn't mean the display is bad. I'm pretty sure your monitor tv, etc don't have AMOLED displays. If it bothers you that much, get a different phone.
[AT&T Samsung Galaxy Note I717] talonted:
Sorry man, you're wrong. Not saying you're a bad guy or have any malicious intent, but you're wrong. My first note displayed Netflix episodes of Lost flawlessly, while my current one is nearly unwatchable in all the dark scenes of the same episodes. This is on the same Wifi network, same speed connection. I will have my 3rd note (warranty exchange via AT&T) in a day or two. If there is any discernable difference between the two, Ill take side by side screenshots to prove it.
[AT&T Samsung Galaxy Note I717] paleh0rse:
Absolutely false.

All I can say is that, in this case, you are totally and completely wrong.

The black clipping issue on the Galaxy Note has nothing at all to do with the source material. The exact same source material that demonstrates the issue on the Note looks perfect on other devices and displays.

You have no idea what you're talking about. Period. Do us all a favor and don't crap on this thread again.

Or, better yet, do the gamma test and see for yourself...
[AT&T Samsung Galaxy Note I717] paleh0rse:
Screenshots won't work to demonstrate the differences -- you'll need to use a separate camera to capture the issue.
[AT&T Samsung Galaxy Note I717] cgibsong002:
I did side by side comparisons with my focus and note. same test image. both super amoled displays. focus fades smoothly to black, note fades smoothly to dark grey then snaps to black. so yeah.. your theory is a bit off.

yeah, I meant shots of the screen. :)
[AT&T Samsung Galaxy Note I717] Reclaim:
All the phones you mentioned are samsung devices. If it weren't for the large screen, I would have stuck with the HTC Vivid. It didn't have this problem. It's not a deal breaker for me obviously, but let's call a spade a spade. I don't have a single other device that has this problem with the same video files. TV, phones, monitors, etc. I'm being completely impartial. Super LCD > SUPER AMOLED. Sorry.
[AT&T Samsung Galaxy Note I717] PeartFan40:
Results will vary. I also mentioned other non Samsung devices. I'm beginning to believe it may be more prevelant with AMOLED displays, but the link I provided clearly proves that this issue is not limited to the Note. As I stated earlier, I'm not trying to be a d*ck, just trying to put people's minds at ease.
[AT&T Samsung Galaxy Note I717] PeartFan40:
Id like to add that some people have unrealistic expectations when it comes to phones. All manufacturing facilities have specific tolerances. Certain minor flaws are acceptable. I used to have unrealistic expectations, and that wore off. Nowadays, when I buy a phine, I do so with the understanding that there will be a slight flaw of some kind. It is what it is. Someone once told me that as long as you're looking for something, you will usually find it.

100 percent not a source issue. I used the same gamma test image on a thinkpad w500, precision m6600, and my external dell u2711 ips screens and they are all perfect.

With the note, on gingerbread it dropped to black on 1 and on ICS it dropped to black on 6 or below... using the same test image.
