My Samsung Wave, Galaxy S and first 2 Galaxy S2's never had spotty blacks but my Note and tab7.7 has. Not every phone has it but its pretty annoying if its visible with normal use, if you can only notice it with an all black screen then it should not be such a big deal.
[Galaxy Note GT-N7000 General] truelies1:
Any solution on this black block problem? Every movie has this problem when the it in black scenes. I tried Mp4, also even mkv with 6M bit rate.

BTW, the samsung video in note doesn't have this problem, maybe due to it's pure black. Obviously the Samsung thing is not as good as APPLE.

hmmm... i think it's not a good idea to write your 3rd posting like this...
[Galaxy Note GT-N7000 General] Note_E:
Every GNote screen has this despite what others will tell you..

100% True.
[Galaxy Note GT-N7000 General] Rezz:
I might have made a small breaktrough into samsung recognizing this problem, I've been emailing with Samsung in the Netherlands for about a week now, 2 days ago I showed them this video.

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

They asked me to send them my note for repair and told me that they'll look into this situation.

Of course I'm not expecting anything, since there are people who've had 5 screens replaced without any luck, but its nice to have them not denying something for a change.
[Galaxy Note GT-N7000 General] truelies1:
This is exactly the problem I have, just reported to Samsung USA by chatting. Hope more people do this. This is a serious problem.
[Galaxy Note GT-N7000 General] almaalma74:
what does mean? where, when, what... that tweet is very fuzzy
[Galaxy Note GT-N7000 General] TempusFudgeIt:
Wow! I now see what others are talking about. I have had my Note over 6 months and am so glad I never had this problem with Video. There is always some minor banding at low light but I never have the phone brightness that low as I enjoy the colour so much. Good luck with all that have this problem - I do hope you get a resolution (no pun intended!)
[Galaxy Note GT-N7000 General] TML1504:
i second this! i've seen a bunch of amloed screens, ALL of them suffer these "dark blotches" under low-light!
[Galaxy Note GT-N7000 General] paleh0rse:
The gamma issues (black clipping) are much more pronounced (read: much worse) on the GNote than on any of the other AMOLED devices. :(
[Galaxy Note GT-N7000 General] MR.change:
Then you haven't seen a galaxy SII

My previous SII never had blotches in dark areas , little colour banding yes , but not blotching .
[Galaxy Note GT-N7000 General] EdgaBimbam:
yes i can confirm this, but the reason why it hasnt maybe is smaller screen?
[Galaxy Note GT-N7000 General] TML1504:
lol, as you can see in my signature i have a sgs2, and i'm 1000% sure your device suffer the same issues as mine. as with my note, i've seen quite a LOT of sgs2's, every single one has this issue!

go in a totally dark room, and display a total black image (screen on!!). after a few seconds, when your eyes have accommodated to the darkness, you will see that

a) amoleds are not 100% "dark" when turned on, even when there is NOTHING to display; and

b) the "grey glowing" is uneven as hell, with "darker" thin lines and blotches!

i bet 100$ your device suffer this issue as well! :)
[Galaxy Note GT-N7000 General] truelies1:
Does this problem due to Samsung not test they phone carefully or it's a big problem for Almond Screen?
[Galaxy Note GT-N7000 General] TML1504:
as all of the amoled devices i've seen so far suffer from this (some more, some less, but no unit without) it seems to be a manufacturing problem...

maybe with laser lithography things will get better in terms of uneven coloration, atm (or at least for the devices i know) "standard" lithography is used!

but: the thin black lines and/or the blotches seem to be some sort of dirt which either will be "transfered" though the lithography or in any further step in the production process!

anyway, i'm sure at least the R&D of samsung is aware of this, but only a minority is complaining about this specific issue, and they are economic thinking guys for sure!
[Galaxy Note GT-N7000 General] jackleung:
Well, my previous GS2 really didn't have that problem. I play music video on my devices a lot, and the same set of videos didn't have that problem on my GS2 but they do on my Note. Too bad I traded my GS2 for the Note, if not I would get your $100 for sure.
[Galaxy Note GT-N7000 General] truelies1:
Everybody should report to Samsung. So they can fix this, I'm wondering they didn't test it.
[Galaxy Note GT-N7000 General] almaalma74:
this is only a bad factory setting, ICS w/ its new driver will solve it keep calm.
[Galaxy Note GT-N7000 General] MR.change:
I will gladly take your money sir :)

Not all SGS2 units had this problem , mine had a very even very dark Grey screen when displaying black screen in a dark room

My friend had those blotches on his S2 however , but even on his faulty screen you can never see any black blotches in regular and every day use , it has to be a totally black image in a dark room for you to even notice it.

However on the note I noticed something was wrong after only 15 minutes with the device , the blotches are very clear and very obvious in any dark image/video even in a well lit room.

I even compared the same images on both devices and what appears as a horrible mess on my note appears fine on the	S2.
[Galaxy Note GT-N7000 General] aguadilu:
I wish you were right. I'm on ICS beta and it still happens...

[Galaxy Note GT-N7000 General] zas311:
I guess the digital pen panel underneath the amoled panel emits some kinds of electric power for the digital pen so the amoled glows even though the pixels are 'off' for the black. So it becomes dark grey instead of pure black. If there were an option for diabling the digital pen, i'd like to test it. That might explain almost all Notes have the problem while s1 or s2 are ok.
[Galaxy Note GT-N7000 General] TML1504:
sgs2 had no pen and the same behavior! it's like the difference of standby (display controller is active, although it sends no "lit" commands) and real power off of the screen! EVERY amoled shows this "issue", it's part of how it works!

---------- Post added at 10:31 AM ---------- Previous post was at 10:28 AM ----------

as much as i want to believe you, as much do i doubt that there are units without any blotches or lines in complete darkness.

believe me, i do not want to call you a liar, maybe we are talking about different things. for me it's fact that i've seen 20+ devices and ALL of them had this issue more or less!

can you make a picture at ~ISO 800 and medium exposure time?

[Galaxy Note GT-N7000 General] Rezz:
I'm turning in my device for repair tomorrow, Ill keep you guys posted on the results.
[Galaxy Note GT-N7000 General] truelies1:
I believe Samsung is making very low quality products.
[Galaxy Note GT-N7000 General] MR.change:
Well I don't expect you to believe me ,but believe this :

I don't lie !

Besides ,what would I benefit from lying about this anyway?

Also yes I think we're talking about the same issue , cause I've read about it before, and I tried to reproduce it but my unit just didn't have any deformations when viewing completely black images !!

Although what it had was a yellow tint to the right side of the screen ,a tint that was fortunately removed via a software update (don't ask me how , it just did) , sometimes when I reboot the yellow tint is there again ,all I need to do is turn the screen off and on and it's gone.

As for a photo , sorry but I sold my unit so I guess you just have to take my word for it.
[Galaxy Note GT-N7000 General] kopitalk:
I went to service center due to horizontal dark lines and blobs on my Note which were quite obvious in gray background. They acknowledged the problem as 'LCD black lines' and replaced the display. When I get back my Note there was no more horizontal lines, but now I have vertical lines and greenish tint on the top left corner side and pink tint on lower right corner, but no more blobs. I went to them again explaining the problem but they gave me another 2 sets to compare. Sad to say, each has different diaplay problems too! So I just accepted my Note and if the problem worsens I will go back to them again.
[Galaxy Note GT-N7000 General] kurayamix:
I guess new batch of GN product don't have this black banding issue.

Since my friend just buy new GN (The blue one not black or white)

And it's has no problem playing black video at all...
[Galaxy Note GT-N7000 General] truelies1:
No, just bought one still have.
[Galaxy Note GT-N7000 General] skorpioneMM:

Purchased a Note 1 week ago and still with this same problem.

too bad :(

so my friend just got lucy then...

poor samsung QC. :mad:
[Galaxy Note GT-N7000 General] Tinderbox (UK):
I have had this phone for a couple if days and i have this problem, bad in dark scenes in video`s, what is the chance Samsung is working on a fix and will release it with ICS?

The thing is i only have a few more day`s to return my Note for a refund, after that i will be stuck with it.

Thanks.

John.
[Galaxy Note GT-N7000 General] kurayamix:
I think this problem canbe slove with software. (etc. Voodoo Screen can reduce this problem to minimal...)

But It's clearly QC problem... because some device don't have this problem at all!!!

I think it'll be really hard to fix since level of this problem don't same on every device.

So there won't be "one patch to save them all". Or something like that.

The program need to be optimize or configable in each device....

I advice you to try to replace it if possible. (You may have a change to get perfect one) If not you'll regret it later...
[Galaxy Note GT-N7000 General] Tinderbox (UK):
You need root for "Voodoo Screen" don't you? , I want to keep my Note Stock, apart from the blocky video that is.

John.
[Galaxy Note GT-N7000 General] paleh0rse:
if/when there is a fix from anyone other than Samsung, it will almost certainly require root.

supercurio actually stated that he found the kernel-level problem, and that he has a soft fix in the works; however, he also said that it will require the official ICS source to be completed.
[Galaxy Note GT-N7000 General] CuraeL:
Samsung goes trollololol. How can they say that this is a function of the screen? The screen is one of the best in the market but they still can't just call it a function, since as a function it would have to bring goodfeel and such. I don't see how clipping is a function. If it is, lol, I would advice Samsung to remove this "function".

As Blizzard use to say about WoW bugs; "Working as intended."

Hi.

I have been converting a few of my dvd`s to see if the problem is made worse by bad conversion, low quality rips.

So i picked the darkest dvd i could find "Pitch Black " , I am using DVD Catalyst 4 and I modified the Galaxy Note template to 1500kbps fixed bitrate 2 pass at 1280x800 - crop mp4 setting =1.3gb and it`s looking good when i play it back on my Note, no sigh of major black blockiness, blacks are black not gray, this is only my first test, and is not conclusive, I am currently doing an dvd resolution version Pal 704x576 - crop and see what that play`s back like.

If i can get away with converting my own dvd and they play ok, I will be happy until their is a fix found.

John.
[Galaxy Note GT-N7000 General] clandestino123:
Interesting post. However I think that when you try out the dvd resolution, then the problem will become apparent.
[Galaxy Note GT-N7000 General] dvdcatalyst:
Hi John,

Thank you for using DVD Catalyst 4,

I just converted a 720p version of the Prometheus trailer (I looked for a Pitch Black trailer, but they were all in SD) using higher quality settings, which should make it easier to determine if it is an issue on the Note itself.

http://www.tools4movies.com/trailers/prometheus_trl1.mp4

if you visit the link on your Note, it will stream, so make sure you are connected to wifi.

(edit: make sure you play the video using player with hardware-decoding enabled)
[Galaxy Note GT-N7000 General] Tinderbox (UK):
Hi dvdcatalyst

That video played great on my note, no black blochyness and only slight banding, very watchable.

John.

EDIT : I have asked a mod to create my own thread starting at post 739, as this is supercurio thread and not mine :o
[Galaxy Note GT-N7000 General] dvdcatalyst:
I am glad to hear it John,

I have to admit, I just jumped into this thread based on your post about using a dark video for testing on the Note. I just skimmed through the first 100 posts of this thread, and from that it seems that the color issue is mainly GUI, but I could be wrong.

I'm digging through the rest of the posts and see if I can find out more about what is going on.
[Galaxy Note GT-N7000 General] Tinderbox (UK):
Both the stock note video player and my MX player Pro , has hardware decoder set to on, and they both played back fine, I have watched that video clip a few times now and it`s great.

Though that prometheus trailer has a bitrate of 3708kbps so it should look good, god know how much space a movie would take, I am using 1500kbps.

John.
[Galaxy Note GT-N7000 General] dvdcatalyst:
I used CRF at 20 for the conversion of the clip, which automatically adjusts the bitrate to match a consistent quality. Not the best choice for streaming video, but it does ensure that the quality is and remains really good. Trailers have a lot of fast-switching scenes, which spikes the bitrate. I estimate that the full movie, at 720p res with the same quality as the trailer would end up around 2.5GB or so.

During fast scenes the bitrate would spike to 3700 (or higher) but for slower scenes, it might drop below 500 even.

But I just skimmed through the thread, and even tried a few of the videos and images on an a100 and my gnex (I had those handy) and compared the results with some of the pictures people took from their banding issues.

The issue reminds me about the HTC HD2 WinMo phone from a few years ago. On some HD2's, it had an audio-sync issue when playing video files, but on other HD2's, the same video played perfectly fine. Something related to factories using different type of electronic components os something like that.
[Galaxy Note GT-N7000 General] Tinderbox (UK):
I read that when doing a double pass encoding CBR was not required? , Also what is "CBR at 20" ????

Thanks

John

EDIT : see link below.

[Galaxy Note GT-N7000 General] dvdcatalyst:
I don't want to hijack the thread, so I'll PM you with more details.

CRF is similar as 2-pass, but rather than using an "average" bitrate for the video (the 1500Kbps you selected) it uses a fixed quality setting, and adjusts the bitrate to whatever is needed to achieve that level of quality.

It does this in a single-pass, rather than 2-pass, however, as a result, the file-size differs per movie, and can not be estimated.
[Galaxy Note GT-N7000 General] Tinderbox (UK):
That sound very interesting.

John.

---------- Post added at 07:46 PM ---------- Previous post was at 06:59 PM ----------

dvdcatalyst , I have tried CRF at 20 and a bitrate of 1500 single pass, and i get black blocks showing, I am going back to double pass with CRF at 20 enabled.

John.

It might be better to continue either by email or by pm. This is not the thread for troubleshooting.
[Galaxy Note GT-N7000 General] rmgill:
Just received my Note in the mail today and I really wish I had come across these black crush threads before I ordered. This trailer looks very disappointing on my brand new Note. Even the parts that were simply a black background with text looked dark gray, like I was watching the trailer on a ****ty LCD screen with light bleed issues. Is this part of the black crush problem? From what I have read elsewhere simply displaying a completely black background with text shouldn't be an issue. EDIT: Nevermind. Looks like it's definitely part of black crush syndrome.

For comparison, I watched the trailer on my Sprint Epic 4G (Galaxy S1) and the trailer looked fantastic - blacks were as deep as can be, to the point where I couldn't tell where the black parts in the video stop and where the bezel of my phone began.

If this doesn't get a solution soon my Note is going straight back to Amazon - video is almost unwatchable compared to my GS1. Going to fiddle around with other test videos and software Bandaids that are floating around.
[Galaxy Note GT-N7000 General] Jay-Taicho:
I'm sure this is mentioned somewhere in this thread, but if you're up for rooting and installing a custom ICS rom, you'll see a definite improvement.

Also, changing your screen scenario to 'UI' and screen mode to 'dynamic' darkens the blacks a bit too.
[Galaxy Note GT-N7000 General] rmgill:
Yeah, I will be doing so. Have watched some more video today and it does appear to only affect scenes with certain kinds of lighting. Maybe I can live with it for now. :)
[Galaxy Note GT-N7000 General] Tinderbox (UK):
Well i returned my Note Today :( and i really loved it, it had a physically great screen nice evenly white no yellow, but i could not put up with the video quality.

Well lets see what the Samsung brings us in a few day`s :)

John.
[Galaxy Note GT-N7000 General] paleh0rse:
4 of the last 5 videos I've watched on my Note have looked terrible -- with the new trailer for COD Black Ops 2 being one of the worst.

It's such a damn shame... :(
[Galaxy Note GT-N7000 General] Rezz:
Just got my Note back with screen replaced, no difference what so ever, black clipping still there and dark scenes are still unwatchable.

I guess I just have to wait untill ICS is released and either samsung or Supercurio provides a fix :(
[Galaxy Note GT-N7000 General] electroshadow:
i would think that this has already been mentioned but, i stopped following the thread after page 30....

i bought the note becuase my old faithfull dell streak video play back had become blocky, much to what you guys have been experiencing here. So i got the note all excited and then very dissapointed to find the same problem...hhmm strange, but i decided to hold out as the note was still alot better than my dell and future proof and i thought that ICS would most probally fix the problem ( a lot of fingers and toes crossed).

so i decided to sell the streak on ebay..... thus i did all the resets.... now i thought for some reason to try the video again :eek: oh it works perfect play back again now thats strange and annoying as i now have the note.

but after putting all my standard apps back on the video playback turned back to blocky......

so after some trial and error of resetting and installing apps i have worked out that flash 11 dose not play well with the 5 inch screen on the dell streak. and after uninstalling flash 11 from my note the video play back was better but not fix the blacks still annoy a little but light colours were a lot less blocky.

i dont think the the new flash update works with 5 inch screens. Try it yourselves to see if it makes any difference ??
[Galaxy Note GT-N7000 General] cybamin:
kindly someone answer my question about the screen problem for color gradients:

is it a hardware problem or software (driver)? :(
[Galaxy Note GT-N7000 General] Gianpor:
Well, i've been reading forums around the internet regarding this particular problem, the thing is that i always see that people has the isue below some numbers, lets say 4 and below, or even 7 and below. I believe my divice has a different issue or maybe more pronounced.

As you can see in my upload, it has several color issues, or at least that's what i can see, if anyone has information regarding this particular issue, please let me know.

Thank you in advance.
[Galaxy Note GT-N7000 General] pboesboes:
Holy crap! That is NOT normal. Get a replacement if you're still under warranty!

Its broken. Send it back again.

I did and was lucky to get a good one second time.

Samsung must be wetting themselves laughing at people accepting this crap.
[Galaxy Note GT-N7000 General] Gianpor:
well, i did change it, but i got the black clipping problem on my new device as well, i couldn't see it clearly back then when i was at the store cuz of the light.

back then i didnt have the test image so i didnt check my first device, but the video i used to "test" it looked the same, i can only assume it had the same issue. i am not sure if they will give me another device tho. I will keep you updated with my case tho.

Thanks for your fast reply.
[Galaxy Note GT-N7000 General] Rezz:
Are you saying your note displays the test images correctly?

Can you post a photo of this do I can show the people at the service center what its supposed to look like?, maybe then theyll take me seriously.

Cant remember what the test images are. Havent been to this thread for a long time.

I am sure they know it is not supposed to look crap.

[Galaxy Note GT-N7000 General] squicky:
I don't know if SGN has got some issues with png files, but the gammatest.png on my SGN was looking almost the same as Gianpor's - colors when there should be gray and black. So I converted it to jpg and now it's pretty normal grayish shades. When it comes to videos I think that black squares are somewhat connected to encoding method and specific settings (I'm no expert but I have eyes :P ) as I'm watching lots of anime even 1080p and often I can find it there but other time I'm watching 720p and I don't see those squares. SGN might work better with some and not so good with others. I bet it must be driver issue in 90% of cases.

UPDATE:

I've watched this Prometheus trailer and there was no true black, only gray background. But in lightness and slimness black is TOTAL, can't distinguish background from the frame even though I'm in perfectly dark room. I've tried some other movies and I've only seen black squares where there was high speed scenes and everything was blurry and moving but I don't feel like it's the phone fault. I would even say that there maybe case that codecs are using known inability to show black by consumer range LCDs to compress material more in dark scenes, because on consumer non OLED LCD screen we wouldn't notice the difference, where on SGN we surely would.
[Galaxy Note GT-N7000 General] Gianpor:
well i downloaded the gamma test again from somewhere else and it looked better this time, but still i got some issue, i feel relieved now cuz eventho i still have the issue, it's not as bad as it looked before, i guess it is more likely that i can get it fixed, either supercurio's fix, or samsung's ics. i'm looking forward to get either of them.

thanks again for your support.
