Possible Screen Issue. Need you guys help. - Galaxy Note GT-N7000 General

So I recently got a Galaxy Note and tried some wallpaper i used on my galaxy nexus and there is strange distortion in the image where the colors transitions. I'm interested to see if this is the Galaxy Note or just my Galaxy Note. Can you guys place the image on your devices and see if it shows the same distortion.
I attached the image to this post so you can put a clean image on your device.
Here is where the distortion is but of course you won't see it in the image unless you are looking at it on your note.

i see wht u mean ... i tried it...but i think it happens becuz the pixels turns off under the colours becuz it's black ,, u cnt see it on lcd i guess if u tried
another possible issue it's becuz every pixel has 2 sub pixels instead of two so..it cant move to another colurs

I considered that but the Galaxy Nexus has pentile display as well that is Super Amoled. I would expect to see the same thing on that device but it might be that the pixels are a bit smaller on the GN. I honestly don't know but it concerned me a bit.

I cannot see any difference between the image on my phone and on my laptop.
I have tried with Screen Adjuster at 75% and -40 contrast, and without.

Interesting.. Do you have a white note or a blk/blue version?

This is a common issue in the Q/A section. Look for the a thread about video playback issues.
In short, the Note does a very poor job at rendering black levels. At some point, it completely drops off and instead of rendering a low level black, you get a completely turned off pixel. This creates the "black pixelated" effect in the wallpaper that you see. You can see this same effect if you took the default ICS stock wallpaper. You'll see it in the bottom left side of the wallpaper when viewed from a note.
Supercurio is working on a fix. People are also hoping that ICS will provide some relief to this issue so sit tight.
It is not a hardware defect, rest assured.
This effect will also occur in videos with dark scenes. One temporary remedy for now is to use high-resolution wallpapers and high-resolution videos. If you can, try using a 2500x1600 wallpaper or something higher. This reduces the black clipping/pixelation a little but does not eliminate it. Using a brighter themed wallpaper would help as well.
If you're using a dark wallpaper thinking that it'll save you power, don't bother. It is not significant power savings due to the fact that you'll swipe through your home screen and your brightly colored icons would have activated the parts of the wallpaper that were dark anyhow.
Cheers.

ahhh haa.. Thanks for that information. I have yet to see it in a video or paid close enough attention to catch it. I'm not too worried about wallpaper but when i saw that i was like hmmmm what is this about.
Thanks for that info. That answers all my questions.

This is the black crush issue which is discussed on the video issue, it also happens with images/games and basically anything on the screen.

Same issue for me

absolutely no pixelation on my note.
smooth transition to black

I'm aware of the issues, but there is no pixelation on my note. not with this particular picture. sorry

Its interesting... After i read the post about the pixels being turned off the issue disappeared but I did lower the brightness and it did come back. Its apparently not an absolute under every circumstance but its definitely an issue. I'm less worried about it now though.
I gotta wait till ICS to make my final decision on whether to keep the note or to go back to the nexus

Black on SGSIII not totally black like SGS I

Hi all SGSIII owner, have you try open your phone in the dark room? Look at the black colour such as in the Settings menu. The black not so black, like the Super AMOLED still lighting not like my previous SGS I. I think, this also drink battery juice faster.
BUMP!
Oh noo!! What is that? I open facebook in my dark bed room last night, when I open a photo from my friend posting, and waiting the photo loading, normally I saw black background and animated circle. But today I noticed total black dots in the background.
I managed plotted the dots in Photoshop, it look like this:

Another one issue is dimming.
I test the dimming function from keyboard key-in *#0*#, it not dim like first time I test after I bought the phone. I test the red, green and blue screen still ok, no issue.
What should I do?
I would drink some more juice -
the dots are ink marks that have been known to exist on samoled. According to supercurio, it's a software related problem and should be fixed by his app soon.
back I the sgs day, i didn't have this problem until I flashed cm7, it started happening. I thought my screen had a burn I or dead pixel lol

the OP is not talking about black spots/blothches man ( his 1st post issue) , hes talking about the depth of black color ...its very dark grey and not deep black like on the s2 and even s1....u can notice it mainly in dim lighting or dark rooms...
even i have this issue, wanna know if all sgs3 panels are like this !!

Oh I see thanks for the clarification
My Galaxy S II had this issue really really badly, to the point where the keyboard and statusbar were lightly burned into the display. Keyboard was temporary but statusbar burn was permanent.
Galaxy Nexus had it a little better, only one very obvious black spot on one of the on screen navigation buttons (which were always black making it more noticeable)
Galaxy S III hardly has it at all! Was planning on taking it back to the carrier (first phone I've got on contract in 12 months) if I noticed the issue badly, but since it's so little (only a few tiny dots) then I'm going to keep this one
I remember a discussion about this on the Galaxy nexus forum. It's just a limitation of the amoled he technology that they can't make the blacks as deep anymore. Personally I think the higher resolution is worth the sacrifice.

look, the spot/ blotches issue is alright if its not too noticable....so thts fine....
but the blacks not being deep enuf, thts too bad considering s1 n s2 had nice deep blacks...
so basically the Supr amold " HD " screen exclusively has this inability to dispay true blacks ???
P.S: yeah the resolution is great, so much better thn the s2 !! love it !
I use this video to test the black on my note, play it in a totally black room, if you have true black you should not be able to see where the edge of the display and the bezel join.
My note`s black`s are pure black not gray.

Blotches on an all black screen? Test yours here

Can you guys with cameras that have manual control test something for me?
Following on from a post by someone else about weird blotches on an all black image displayed on the screen, I checked mine today in pitch darkness and noticed a faint 2 inch or so of blackness on one edge of the screen along with smaller blotches. It doesn't appear to be as visible as the other poster's though but I exaggerated in in the photo so it's easier to see and settings posted below for people to check as well.
This is only visible on an all black screen. This does not exist on any of the S2's I've owned. I'll check my dad's S3 tonight when I go see him in the same way but the way to photograph it to keep the results consistent are as follows:
Stick camera and phone in a cupboard and...
Phone screen brightness: 50%
Camera ISO: 200
Camera Shutter: 15 seconds
Camera Aperture: f/4.5
Remember to pre-focus and use the 10sec timer to avoid shake
Those settings will over exaggerate the effect as shown in my photo below but it makes it easier for everyone to see as you do have to focus your eyes in reality and it's not immediately obvious unless you're in pitch darkness and looking at an all black screen.
I don't know how I feel about this though but if it's visible using the above camera settings for lots of people then I'll leave it as is.
Again, it's only visible on an all black screen so make sure your image that you load is all black and not grey or something Make sure screen timeout is set to at least a minute to avoid the screen going off!

I used this free app to notice my blotches. It worked great for me. Your method has alot of steps in my opinion.

What free app? It's a black image with screen timeout extended. The rest is your camera settings to be able to fairly photograph the screen for everyone to compare, an app can't do that

I didn't see those nope! Thanks for the links. Seems strange though as the white S3 belonging to my dad has none of the blotches, neither does a pebble blue on another forum. My 2 S2 handsets had no issues either.
Oh well!
My first phone: (F/4, ISO 800, 20sec)
Second phone: (F/4, ISO 800, 30sec)
The guy at the store (**** Smith in Australia) was unable to reproduce the issue in-store, so swapped the phone out and said I'd have to go to samsung if I reported the same issue again. The 2nd phone still has the issue, but as you can see, nowhere near as bad... still... not very good is it.
My 2 year SGS1 had about 4 spots - never noticed any issue. The first SGS3 was definitely noticeable just scrolling through system menus at night.
That's rather bad^^ I've emailed mobiflefun with picture so let's see what they say.
Suggest you up your exposure (duration and/or ISO) to make it a bit more noticeable. Looks like you've got a fair amount of guff in the top-left corner.
:/ dodgy manufacturing.
I don't have an SGSIII yet, but I noticed pretty much this same thing on my Galaxy Note. One night I was viewing an image with an all black screen and it had these weird blotches on the screen. I had never noticed them before.
Actually mine does has it as well but I can't seem to see it under normal conditions

I saw around 10 to 15 blotches on my screen,not at all noticable in everyday use only when i looked very closely i saw them scattered around the middle.As its my first amoled phone,i want to know is it harmful for the screen?Shd i ask for replacement?Though i dont have any pink spots or tints watsoever.

This "issue" is known since the SGS1. Is the leakege from the AMOLED display. One thing to consider i only have a line about half a CM in the same place where you have the circle mark. Maybe a manufacture failure?
quicker way to test.
1 - dark room
2 set auto brightness off and screen to lowest brightness.
go to phone and dial *#0*#
click vibrate test which will display black screen.
and then check....
p.s been through this in other threads here but mky local telco had 26 with this issue went to another telco and got a blue one today - and no issue whatsoever...

Fix for Black Crush/Color issue on Galaxy S3 AMOLED

i tried to fix the black crush/color issue on my S3 with Filter Your Screen

but there is a warning for AMOLED devices:
***OLED screen owner please read***
(AMOLED screen of Samsung Galaxy S, Super AMOLED Plus screen of Samsung Galaxy S II, etc.)
- you should use only white, gray or black filter only.
- using color filter (not white, gray or black) for a long time may cause your screen more color tint. (it's about OLED screen property, not my fault)
- using any color filter other than black will cause black pixel being not 'true black' pixel anymore. (that means some power is required for black pixel)
- if the filter does not cover all of your screen, please uninstall this app because this may cause irregular color burn to your screen.

is this filter going to damage the amoled screen and how much it effects the battery?
I did not realize the S3 had a problem with black crush, I though it was just us unlucky G-Note owners
We have just been using the free "Screen Adjuster" app , but it kills the battery and makes blacks gray.

I definitely have a black crush issue with mine. I've tested 4 and they all have it but one dev has already found a fix for it. Just be patient till its released. Shouldn't be long now.
There's indeed a heavy black crush problem on this device (beside the yellow tint...). Hope some developer will fix this. Dark photos or videos don't show any details on this screen....

Supercurio by any chance? Good luck with that, after saying it was pretty much possible to fix the problem in the Galaxy Note after the ICS source was released, we did not hear much in the thread he started, then after a few idiots tried low tactics to get a responce from him, he got the hump and closed the thread.
This is such a stupid problem, and one that samsung customer services still refuse to acknowledge.
I was told to return my device and get a new one from a different batch, which I did, only to find the new one had the same issue. Now they want me go without my brand new device for 2 weeks while they fix it...wtf!!!
I was considering the s3, but after seeing this I am holding fire.

Yea, it is one of my few real niggles with this handset, but I have faith Supercurio will fix it. He mentioned that unlike the Note, the S3's fix was much easier and purely software based.
Also, I don't think changing S3's will solve the problem. It is my belief that ALL S3's suffer from this issue, it's just not all people realise or notice because it's not generally that obvious.
Now im using Filter Your Screen with (13 Alpha; 255 Red; 225 Green; 255 Blue)
question remains: is this filter going to damage the amoled screen and how much it effects the battery?

look at the pictures in the thread.........
there is not gradual scaling from black to the rest of the color spectrum....if its not bright its Super Dark, no inbetween.
as in watching movies, a dark movie like the crow, or spawn. a lot of the scenes its just to dark to reallly even tell whats going on. but on my TV or even another phone, while its still dark you can SEE the difference in Blacks which defines the shapes of that scene.
or thats what i take from it anyway. i have not read anything just from my phone to other thread and pictures this is what i think it is.
ok, thanks. Now I can name this annoying "thing" when watching avi movies. I always blamed avi files for this. But as I can remember it's a common "feature"/bug in phones. I remember the same on Nokias too.

Make sure you're on maximum brightness in a somewhat dark room and play around with the mDNIe scenarios and modes.
'Dynamic' mode doesn't allow me to see the difference, but others do - but I don't like their coloring.

Very often it's the source file. Compression works by searching for blocks (or other geometrical shapes, e.g. triangles) of approximately the same color and storing them as having the same identic color. The "stronger" the video/image/audio compression, the more such artifacts you get. (Of course it's more complicated than that, since it has to consider 3 dimensions, them being X, Y and time T)
Sometimes players try to correct these issues with post-processing algorithms (which have their downside too), so it's more noticeable on some devices than others.

Now as the phones reaching users can anyone confirm in pitch black the amoled output? To me that's the most impressive improvement dating back to when amoled first went HD on the galaxy nexus and lost that level of output.
Yes, it is totally black. Way better than S3 and Note 2.
The blacks are the best I've ever seen.
The pixels are completely off, as opposed to previous amoled screens where there was still a light glow.
Wanted to give this Q too I had previously SGS2 and SGS3 is it even better than SGS2 display in the case of black displaying? I was very satisfied with SGS2 blacks... THX

It's much better., Infact it''s impossible to get better blacks as the pixels are completely off.
I was always disappointed with previous phones as in a dark room once your eyes focused the blacks would look light grey and you could see blotches and streaks.
On the s4 you see nothing at all.
If you switch your phone on in the dark all you see is the samsung logo on the screen, nothing else.
perfect THX for response I hope that will have zero stuck/dead pixels
That's amazing. It's pretty poor form that all reviews as far as I'm aware have stated the previous amoleds with that slight glow as infinite black.
Anyway the S4 finally has something I'm really jealous of now. Another question similarly relating, does the brightness go lower than the S3?
?????? Galaxy S3 ??????
I think something is wrong with mine. I have the Galaxy S3 and I would say it's a really dark gray, not quite black. But on the S4, I'd say it has a reddish tint to it when I have it all black in a dark room. I may try and take a picture of it tonight.

It is honestly that black that when I was waiting on a video to buffer in my pitch black room that it looked like the blue circle was floating!! literaly no light on screen apart from the blue circle. It actually looks really cool lol

There is a comparison between S3 and S4 black/grey scale in this video, FFW to 17:10 (or watch the whole unboxing and comparison to HTC One video if you want).
You may have seen this by now, but if not it might answer some of your questions.

Dark colors not uniform from top to bottom of display

I'm noticing an issue with my S8 AMOLED panel and curious if anyone else has this issue.
On darker colors, the top of my screen is noticeably lighter than the bottom. This creates a gradient type effect on apps with dark themes. Tapatalk's dark theme, for instance, is very noticeable and at first I thought maybe they updated the app with a gradient background between me switching from my HTC 10 to the S8. Then I noticed it in other apps and when changing the screen orientation, the gradient shifts along with the device.
The S8 is my first Samsung and is my first phone with AMOLED. Is this color disparity common, or should I try to have TMobile replace my device? Thanks!
Managed to capture it in pictures taken using my HTC 10.

certainly contact TMobile to get a replacement, I've seen no such issue with my device
I use dark or black walls and or themes and haven't noticed it either.
i am having exactly the same issue but only in home screen....dark wallpapers are noticeably lighter on top than bottom...any ideas? Almosta as a gradient below status bar...not on apps!!
I haven't noticed this on my S8+.
Is it not because the screen is so tall that you are often looking at it at an angle?
So I called T-Mobile and requested a replacement. They sent me to the nearest retail store and had it swapped out. The new display doesn't have the gradient darks issue. Yay... Unfortunately, this new device has pink edges where the last one did not. Can't win.
My HTC 10 had a pink tint to the screen when I bought it and it eventually went away, so I'll keep the new S8 for a bit to see if maybe the screen bond is still curing. I'll give it a week before I request another replacement.

The AMOLED lottery. Got the same issue with non-uniform black colors as well.
Journalists like to call this the best display on the market - because they get preselected perfect samples. We do not.
That is a defect with OLED panels. Slind hit the nail on the head! Reviewers get a hand-picked perfect version and I don't doubt that their phones do have the Best Display, but we get half-assed defective non-uniform panels that go from yellowish to pinkish looking causing a gradient and sometimes blotches.
This has been going on since the galaxy S6 for me. I will not pay $750 and settle for less. I return/exchange the phones that have these issues and sometimes you will go through 4-5 phones before you find an acceptable one.

Yes, and because of this I don't think it's a defective screen issue. I believe it's a software issue in the setting of the wallpapers for the home screen. Which means, unless a bunch of us raise hell about it, it's not going to be fixed.
same problem here, for me the issue its mostly an issue that creates an odd sensation during gearvr, when play a game withbtoo dark a scene you loose vision in one eye...
Ok, i'm in the same boat, i have an unlocked Exynos S8, same issue on top of the screen with black wallpapers, little gradient... I tested the stock launcher and it's there, then i open in the gallery the pure plain black wallpaper and zoomed in to vie full black and surprise, the gradient isn't there, ok, so IS NOT HARDWARE.... then i test nova launcher and yes, the gradient is there... ok,ok, i tested like 5 random launcher, some of them are perfect with the black solid wallpaper (no gradient issue on top) and some of them had it....
but why touchwiz?.... why the stock... is not hardware.... it's all i can say

Quick update: I you use the store's theme "material black" you can have a pure black top on touchwiz... so yes, god, it's a software issue.... using that theme gives me a pure black top man, again, why not the stock theme... greetings
