[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] MayDay84:
Could that 16bit color issue in gallery etc. be made for performance since there's not a proper support for dual core in Gingerbread?

In browser there are lesser colors when scrolling and amount of colors increases when rising finger off.

I have been amazed of how well Note's gallery runs compared to Desire's 1GHz CPU..
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Well if its for a performance reason, using quickpic in 32bit mode is fast even on previous phones like the Galaxy S1.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] tintin1042:
totally agreed with you today in a mall i saw a demo unit which shows very very few black blocks for the same video which i transferred from my note.

so, how it can be possible if it's a s/w issue???

I'm still not sure if the color banding is a software issue.

I didn't had any color banding since yesterday :S

The color banding seems to be huge on my G-Note now.

But when I make screenshots, and view them on my PC, it looks really good, but on the G-Note it looks awful with the color banding.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Jorkyyy:

Black clipping doesn't bother me so much as color banding... Just see the screenshot... And so anyone sure about what issue is that software or hardware? Just see the sky while I play GT Racing motor academy...
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
This is a clip of Iron Man 2, let me know if it doesnt bother you more than banding ;)

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] tintin1042:
IMO Black clipping is much much more irritating than color banding . due to the Black clipping i stoped watching videos on it.Though both are huge problem for me and one can't expect such flaws from such expansive phone.

Wow when I use screen filter turned down to 20% the right part of the screen is darker and some kind of pinkish (that happened only on some scale of grey) I'm happy that with white it's fine, unlike my previous Note :D ... But wihout using this application I have never seen that kind of problem... Why you showed that to me :eek::D

PS. Also the black clipping in Iron Man 2 is truly awful :mad:

PS2 I made second test, but this time using app screen test and screen filter and know I can't see any disturbing differences
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I just grabbed screen filter and set it to 20% and I noticed that its not actually getting dimmer BUT getting a greyish overcast on everything I dont see any shadows on a pure white image though but it now looks like grey instead of a faint white.

EDIT:

Are these shadows visible even if dont use the screen filter app? It might be a OLED limitation as to how reduced brightness it can do and is already out of spec (probably)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sibere:
I see all levels to 1 even in non-32 bits mode with QuickPic.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] rey5757:
20% and color is Balanced? U must hv got the perfect screen, or near perfect screen!!!!:cool::cool: I gotta see this for real, can please up some photo?

---------- Post added at 05:05 PM ---------- Previous post was at 04:53 PM ----------

Yes they are visible even if not using screen filter, I can easily prove it cause i have a real bad shadow screen.

If u are on firmware 2.3.6, in default web browser, there is actually a powersaving setting which do exactly the same thing as Screen filter.

Turn it to max, turn the brightness all the way down, the same shadow at same location should appear let say in google white background, if u wait for a while, just before the screen auto turn off, it will get even dimmer. that will probably reach the same level as 25% of ur screen filter.

edit: mistake: manual brightness all the way down is the dimmest already, wont get dimmer before screen auto off..
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Sorry I dont understand how that relates to the performance level.

The color is balanced as far as I can see, but Im getting a grey over cast on the entire screen isnt screen filter supposed to lower the brightness instead of messing up the gamma?

No I dont have a perfect screen, I have issues of my own. The last perfect screen I had was on the Galaxy S1, Absolutely stunning even until now.

The dialer screen shows how its affecting my display at 0% brightness with screen filter at 20% I get a grey overcast on everything! Im pretty sure its supposed to be dimmer instead of getting a greyish tint.

I've added a shot for the default browser at 0 brightness with power saving to 0 and another shot with power saving at 3, it turns the screen into a bit blueish. The blueish moire at the bottom is caused by the camera.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] rey5757:
i think screen filter changes the white to grey, hence color intensity, to save battery on amoled display since white comsumes most power. just like what powersaving in browser did to blue?.. the only brightness is really the brightness in setting... that will explains the grey tint.. Saw the white one, ur screen is damn balanced!! definitely better than what me and some other people are having.. And better than the demo one i saw in malls too.. Why is that.....
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] joshoon:
How have you been able to capture it on a screenshot?

Because when I make a screenshot, and view it on PC, I have no color banding.

It's only on the G-Note's screen...
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Random quality control I guess.

EDIT:

If you look at the photo of my dialer does it also look like that on your end?

I think the apps that are actually running in 16bit will show banding on screenshots since the image is taken from the frame buffer ( before it goes to the screen ) while apps that dont show any color banding are probably made with 32bit color but the andriod system/samsung firmware is forcing it to drop to 16bit.

Just my theory.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] betoNL:
LOL...now I get it ...

So tell me why would I waste my time, working with obscure video clips downloaded / re-uploaded / converted / decoded /stretched by whoever to whoever for whatever purposes, if I can enjoy from the same video from better and more reliable sources, perfectly viewed on the beautiful screen of my Note, with no blocks, lines or whatever??

The same clip (rusty nails - moderat)!!

TIP # 2 : Open the following link with OPERA mobile browser ( free from the market):

http://www.pfadfinderei.com/motion/moderat--rusty-nails#/0

I will upload a better sample of rusty nails soon....and when I have more time, will make some GNote videos myself to demonstrate how proper HD video clips are perfectly viewed on my Note

And lots of other stuff
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] joshoon:
Ok, but why didnt I had this before?

It started yesterday!

Before I had no bandings at all, the colors were beautiful, with every app, and now with the same apps, it is full of bandings.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ankydu:
I am litereally fed up from the changing hue of my fifth note in addition to a stuck pixel. Well samsung have made me used to the dead pixel so much (even my sammy plasma has it) that now I am not bothered by it.

But the screen reddish from top and greenish from bottom is really bothersome.

Check out the various pics I ve attached with this post. The ones with the email client with grey background and the s-planner app are with 0% brightness. And the ones with dialer, google page and screen test menu are with the screen filter app with 20%. The last pic is of the rusty nails video at 00:20 duration. Please ignore the bubbles of my crappy scratch guard and grains of the dark image after activation the screen filter app.

I request you all to please comment on how good or bad my screen is and should I go in for a replacement.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
lol, no you still dont get it. The sample video is actually from supercurio and that is his own link and not mine, I would not go so far as to in-directly accuse him of touching those files to suit whatever purpose. My full reply on the proper topic here , since this thread is mainly about hardware screen issues so lets move to the other thread where its more appropriate.

The banding was there you probably didnt notice it yet, its a 16bit color rendering issue.

---------- Post added at 03:30 AM ---------- Previous post was at 03:18 AM ----------

If you've stumbled across my post before I had that green hue before but not that severe, that is obviously ( and severely ) a broken screen. Your already on the 5th replacement and people say users with screen issues are the extreme minority its like 1 in a million or something.. I cant recall the figures they pulled out of no where.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] DPMAce:
I would just return it for good if you're on your 5th phone.

After doing the screen test, mine has no stuck or dead pixels. But it does have very light banding I guess. I can't even really tell, so I'm satisfied.

What problem I do have is the touch screen is glitchy sometimes.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] betoNL:
So I downloaded the rusty nails video from the link I posted before, but it came with a weird extension .qt

So I converted it to avi keeping original size and codec and the bitrate is 1024

Download it from here and report the issues you are having:

Download sample

Run it with Rockplayer or any other player that support avi

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Odd, the original video is in .MOV if you download it directly from the site.

EDIT: your re-encoded/re-touched vid still clips but not as bad as the 'original' file from supercurio. Played it using Dice player as Rockplayer does fancy things with the background.

Revelations

Today I was lucky to meet two people who each are Note owners.

I tried the calculator and immediatelly didn't notice banding in the blue color.

Then tried some test video and no black clipping either.

So now I've exchanged a month ago once my faulty Note and it seems that I received a faulty one in return.

But there are Note out there without this problem , I've seen at least two of them. Both Note runs on KK5 but mine to . All were purchased in Belgium but at three different shops.

So I'm gonna try to exchange my Note once again or at least let him repair.

But it seems now that we can rule out a software default and stick with a hardware problem ( probably faulty quality build and/or control ).

It's possible that some software solution will be available to partially solve or at least hide the problem . But I will only be happy with a perfect unit.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] joshoon:
No, for real, it wasn't there before!!!

Even the PowerAMP EQ has a different color now, grayish.

Also my background didn't showed so much banding before.

So, what's the point for having the most expensive phone when I could't enjoy watching movies (because of black clipping) and I couldn't enjoy games (because of banding)...

People will just tell you to get a Plasma to watch movies and a gaming console for games, some would also say 'its just a mobile phone get a life'

Its pretty hard for others to understand what we are going through with this panel lottery.

My friend opened a page on Facebook for us, guys!

Hello friends,

As long as my question-posts were being deleted from Samsung Facebok page, i asked my friend to open a page for all those people who fell victim to a factory defect of Samsung Galaxy Note line.

So there is a page on facebook called "Samsung Galaxy Note - Screen Issues", here is the link:

http://www.facebook.com/pages/Samsu...xy-Note-Screen-Issues/154264438017212?sk=wall

You are all welcome to upload to the page photos and/or videos, which can illustrate the issue, and duscuss the issues on it, in order to draw an attention of those new owners of the device who don't notice the defective screen, or simply think that they are alone in this mess, like most of us were.

Also like and share the page in order to reach more people, maybe they or their friend own a defective GNote.

This will give us three things.

1. We will be able to see how spread the phenomenon is.

2. in what countries the issue exists.

3. Have a proof that this is a widespread issue, and demand from the Samsung company to replace all defective phones to new and good ones, and stop selling the defective line of products.

Please cooperate with this and hopefully we will be able to get a good working phone we paid for or a refund.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] joshoon:
I think it's a hardware problem too, since I didn't had the banding before.

I will compare soon with a friend which has a S2, quite the same phones so, and people report the same problems with the S2.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
I don't think it's a hardware issue.I think Samsung tuned the display for maximum color saturation to appeal to the masses but at the expense of black rendering.I have yet to see a display that has sharper colors than the Note and this includes the s2,iphone and Nexus.

Unless Samsung decides to fix this,the only thing you can do right now is to use the app screen adjuster and set the contrast between 40 and 60 depending on how severe the black crushing is on that particular video.Some are worse than others.This will compromise the deep blacks and the color saturation but is better than nothing.

This issue is not a big one for me as I watch all my movies on a dedicated 50in plasma.I'm not going to waste a good movie watching it on a 5in display as I am not 10 years old anymore.The quality using screen adjuster is good enough for casual watching.I cannot believe anyone is looking for a plasma beating performance from a mobile phone display.

The next generation of amoled may be perfect so wait a few years before getting a GNote and go back to a smaller display if it troubles you.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Thats great, I also wish this is a non issue for anyone and not watch movies or or anything of that sort on the phone. So run along now as you've made your point :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ankydu:
Another issue is the hue jumping between greenish and reddish. What i want to know is does it happen when u touch the screen or it keeps happening on its own, like on mine.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Earl,I am just trying to bring some balance to this whole issue.Someone has to otherwise this thread will make like the GNote is a useless piece of sh!t and that's not fair to an average user reading this thread making them feel bad about their new purchase.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Saying that its a non issue for you is not bringing balance but just putting your opinnion (which is fine) but indirectly dictating that people should not expect any good movie play back from this device is not bringing any balance, saying that a 5" screen is for kids and we are expecting plasma quality only aggravates the issue further.

I understand that you are trying to defend the Gnote, but I dont see any indication on this thread that makes the Gnote a useless, this thread is not even for the average user to begin with as they barely notice or even care about these things.

How they feel about this issue is on their own and they should not be persuaded other wise, not all gnotes are broken.. its only the extreme minority as some have said.

EDIT:

A little off topic but earlier I was looking for PSVita reviews and I stumbled upon a screen issue discussion which showed a few similar issues we are facing on the G-Note and other OLED devices such as the Galaxy S2 and including the N9. Issues such as lines,discoloration,blobs,viewing angles and ect ect.. and it opened a new insight to me.. anyone who started with a perfect OLED screen ( in my case the Galaxy Wave and Galaxy S1 ) will have a hard time accepting these defects on the other hand those who already started with OLED screen a long time ago will find that the current issues are not as severe as before. These issues are dubbed as 'mura'.

I've had a very long read about the screen related issues on the N9, Galaxy S2 ( carrier versions ) and whats amusing is that most of their reference sources is from XDA about the issue and they point out that even the Galaxy devices have this issue.

http://www.ignisinnovation.com/technology/ignis-technology-overview/ignis-admo-p-technology

I have now accepted the fact that (SA)OLED is by nature defective inconsistent during manufacturing thus resulting in this massive or subtle differences between screens of the same device and there is no perfect screens only screens with a lesser degree of inconsistency.

Hi guys. I don't believe that color banding or pixel blocks in black are really screen issues. If you see the rusty nails video in MX video player with software acceleration on, then they don't look the same with the stock player. Also regarding the banding i noticed also banding in my 55 inch TV when opening WD media player home screen. Is my TV also problematic? I don't think so. In my opinion it is all about the software not the hardware.

However when it comes to vertical or horizontal lines i agree that there seems to be a problem in very low brightness but also seems to become better with each update.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] betoNL:
Can you take a screenshot instead? your pic is not clear

Use the S-Pen for it ( hold it against the screen with the s-pen button pressed)

I am enclosing some screenshots of my Note (Calculator portrait and landscape modes) and my desktop (I just like my new background).

In my case you can see some banding when calculator is on landscape mode on a more stretched image;

it doesn't mean its a screen issue, it just means that some images of some apps are not optimized / adjusted to the resolution/density of the Note's HD screen. ( So I heard)

If you root your phone and alter the density from 240 to 300 dpi, you will reduce banding on many non-optimized images, probably, so I heard.

Now if your seeing banding in almost every image of almost every app and in games as well, so that's an issue
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Thats already been discussed on this thread, the clipping is known to be a software issue, the question now is why does it differ from screen to screen and why do other units not have it as I've already seen one.

EDIT:

@EdgaBimbam

I have the same color banding on the calculator app, even the screenshots posted above show massive banding as well. Since it is screen shot captures the banding this indicates that it is a software issue with 16bit rendering which is already know.
