[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sky|ined:
I got the Note from Orange UK. The first one they sent me came with a really bad screen problem, very obvious bands, lines and "dirty" spots when I lowered the brightness. The second one was better, but still defective so I got a 3rd replacement which is the best so far but...

-Can see faint horizontal & vertical lines on a white background especially when I dim the brightness, visible on any browser and although others might do I choose not to ignore this defect

-Cannot get a true black background on any ebook reading application (HTC Desire amoled I use to own no problem), instead I get a very dark grey with darker spots and a dark line running across the middle of the screen. Verified with "screen test" app as well

-Videos are pixelated, blacks look terrible, low or high resolution makes no difference although the promo video that comes with the device looks perfect ?!

I cannot keep sending my notes back only to get faulty replacements, last time they opened the box before they sent it and supposedly tested for any faults LOL. Is there any way to service this smart device in the UK, properly and as quickly as possible? I don't want to send it back but I will if I have to or I will renegotiate my contract.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
This is a pretty common defect, what is usually acceptable is for it to be barely visible only in certain shades of grey @ 0% brigthness, like the ones used in the market.

I've noticed as well as others that the HD SAMOLED screens dont have the same black levels as the SAMOLED or SAMOLED Plus screens have, a Galaxy Nexus user also posted a macro shot showing that the green and red pixels remain lit depsite showing all black.

Both an issue with the Note and Nexus, the severity varies from screen to screen and this is the main reason why Im processing a refund. I can forgive the horizontal lines and horrible viewing angles (tinting) on my screen but not the blocks.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sky|ined:
Should I get a Galaxy S II then or should I ask Samsung directly to send me a device with a proper screen? I was seriously thinking of buying the tab 7.7 which also uses an HD Super amoled screen but now I'm having second thoughts.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Its all upto you ok what you will do. Asking for another unit means anther shot at the lottery.

I wad also interested on the tab but now im also not sure after all of this.. ill have to see.

Who replaced your screen? Samsung?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Of course, who else do you think ?

Does installing ICS Vanilla or Cyanomod w/ ICS rectify the black clipping in the Galaxy Note? :confused:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] abhi98228:
my screen turned pink while playing 9MM is it normal??

i guess its because of chainfire
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sky|ined:
Maybe Nokia? LOL. I have spoken with UK Samsung's support team and a helpful lady offered a replacement. I pointed her to this thread and she promised a fault-free replacement within 5 to 10 working days and I actually believe her. I'll let you all know in due time how it goes. I'm pretty confident though.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I hope they could give you a fault free screen, the service center here didnt promise me anything but they did process a replacement screen again. They actually do these replacements with minimal fuss and they might have been briefed properly.

I reinstalled swift keyboard x tablet today and i noticed that instead of a soft glow on the font i get color banding instead.. So this is banding is definitely hardware related as well.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Shadowfax2009:
Some solution to Note screen issue??

Hi,

I, like many others have played around a bit with the Note screen. I think it is a software issue....please do this test and tell me/forum if it works.

1. Download the free Sensus live wallpaper from market (VECTORS AND PIXELS INDIEGAMES)

2. Change the color modes in settings and see the banding pattern.

It seems to display best at RGBA8888 mode which I think should be 32 bit png. However it shows up in the app as 24 bit 8888 mode. Here is a pic of the problem. Also the Galaxy note has a screen specs of 800 x 1280 pixels, 5.3 inches (~285 ppi pixel density) which is different from the standard res most application resources come in.

Here is a good description/blog of the thing that I feel is happening with the android devices screen display...it may be worth a read. I am not allowed to post links but it can be found at android.nakatome.net

Here is a bit of excerpt from the blog

"When you place an image resource into the "res/drawable" folder of your project, you are secretly telling Android that it is okay for this image to be converted to a 16-bit format when your project is built, if Android deems it necessary. What conditions need to be met for this conversion to take place here? Regardless of the original format of your image resource, if the image does not have an alpha channel, Android will convert it to the native 16-bit format when your app is built. There are two ways we can keep this from happening here:

Give the image an alpha channel

Place the image into the "res/raw" directory instead of the "res/drawable" directory

By giving the image an alpha channel, Android will not try to convert it to a 16-bit image, because the 16-bit RGB565 format has no alpha channel. Converting an image with an alpha channel to an RGB565 format would cause that alpha information to be lost, so any image with an alpha channel will be stored as a 32-bit ARGB8888 image resource.

By storing the image in the "res/raw" directory, we are telling Android that this resource contains raw data that should not be altered at build time. Therefore, any format conversion will not take place on any image we place in this directory. Unfortunately, we will still have a problem with this method if the image we put in the "raw" directory has no alpha channel"

After reading this and other posts I strongly think that it is the combination of 16bit conversion of the images by android and then resizing with galaxy Notes different screen size that is causing the problem. And it can be eliminated by using 32bit .pngs so that the conversion happens only once, finally at the time of last screen draw.

Does ANYONE have banding in the gradients with the RGBA8888 mode? Please reply. I am having perfect gradients.

Cheers all.

Shadowfax.

I also have the screen issue :(

really started to hate samsung :mad:

got this phone only for big size and high resolution and i didn't accept to have these issues with the screen
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] MartijnMM:
No banding here in 24bit 888 and 8888. But on images i only have banding in dark area's.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Only at the lower left side in the dark area, also I must add when I tried the phase beam wallpaper before which had the same settings it says that the 24Bit (8888) rendering is not compatible and the app would show a warning image instead of the wallpaper but now Im able to select 24Bit (8888) and nothing's been changed on my phone.. odd.. but I dont see any difference from 24bit(888) to (8888)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:

They think that the note is fine and has no issues. I even gave them a link to several forums !

Hi indie, I posted your message to the Faceook page. Hope it's OK.

Turns out that a large number of GNote users don't arrive at websites like XDA because they simply don't speak English, but there are lots of discussions on their local forums, in their native languages, on this same issues.

For your convenience, I post the link to the Facebook Page below.

Its fine. Im pissed off Samsung trying to ignore the issue
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] diament:
I gave mine away for warranty in Samsung service center. We'll see in couple days what is coming out of this all. I can stand banding, ok, but dark colors displayed as gray are unacceptable. Anyway, now I'm afraid I get screen with more problems. Sometimes I hope they dont accept it as fault and return my Huge Lovely Crap ;] After week of testing I can't stand my old SEX10, it's so small and useless now. Oh, I can use it as brick in self defense. Yay!
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] labuharry:
after all investigation with my GN i found something that can ease my tension of this poor HD looking on my screen. if i watch movie using stock player or watching stock youtube app...the quality image looks pathetic on dark scene. but if i watch youtube on dolphine HD browser or maybe other browser too using 720P or higher like 1080P, the issue are COMPLETELY GONE. so i confirmed this issue has nothing to do with our screen or any hardware at all. cheers :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
But didnt you notice that youtube video's dont have blacks anymore, they are now pretty lit up :p
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] labuharry:
hmm im not sure about that and maybe its pretty lit up atleast it shows no blocky image and its perfect for my perception. need to find some youtube videos that got deep black scene i guess. maybe it has something to do with the player setting itself. do anyone here knows any player that has same setting like youtube browser? if yes it will be really nice^^ :) tried screen adjuster but it didn't work well i guess :confused:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Youtube application only goes as low as RGB16, while offline players go to deepblacks which is RBG0.

You can easily verify this by downloading any youtube video with 720p source and tons of dark scenes, play it with the stock player and see the difference on blacks.. forget about the clipping just focus on the black levels. You can use keepvid.com to grab the vids.

EDIT:

Does anyone know of a transcoding app like handbreak that can limit the blacks to 16?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ankydu:
If all these are a software issue, and If samsung releases ICS for Note, Tablet centric ranther than being phone centric, we may see most of the probs gone. ;)

The current gingerbread is developed to be meant for phones and not high res. tablet screens.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
If ICS can fix this then why does the Galaxy Nexus also suffer from the same issue and especially its the flagship andriod phone.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] labuharry:
ouch im clueless about RGB thing. hope some day someone can solve this problem and i really hope this problem has nothing to do with hardware :confused:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ankydu:
Again becoz ICS on nexus is more phone centric than being tablet centric. Since the note is a tablet/phone hybrid sammy shud think about releasing a tablet optimized ICS for it. Plus if you see my post I said it may I did not say it will :) !
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] chong81:
How will "tablet optimized" or "phone optimized" or "high res tablet versions" Android versions cause/fix clipping and banding problems on images, that vary from one set to another?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Its a unified os there's no tablet or phone centric versions and add what's said above.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
Seriously...

Seriously, its confirmed to be a hardware defect. Enough with the debate. :p

ICS is optimized for both tablets and phones, so don't expect any differences. The Note Display is a blow, if this continues on newer models, then Samsung needs a hearing! :mad:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
The artifacts during dark scenes are a lot worse when played through the youtube app.Played using the internet browser eliminates most of the issues.Using movie mode also helps,at least on my phone.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] labuharry:
hmm on my phone using dynamic mode also had no issue on browser. if someone can fix this issue... GN is da best smart phone available :cool:

Basically they are trying to fob me off again to write to their head office. Why could they not forward the issue themselves? I have given them my phone number then why not call? If you are in the UK then write to the address and voice your concerns.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
The email support in my country is done by the head office so in guess that's that.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
That doesn't mean there is nothing wrong with the GNote.It could be that the blacks in youtube videos through the browser are too bright to show up the problem.

There is definitely a gamma miscalibration on most units.I suspect it is done deliberately by Samsung to make the display look more stunning to users.Setting a high gamma number makes the image look more intense and vibrant but blacks won't be dark enough.A large phone like the GNote was always going to be a hard sell and they needed something to stand out.

I have always wondered why the GNote looked more dynamic than the s2 and now I know why.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I find the Gnote to have a more natural color, Supercurio also agrees.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Yes colors look great on the GNote but I was referring to the intensity of the display due to the high gamma number.

I would rather have a less intense looking display for better black rendering like the s2,but there is always hope that a gamma calibration app is just around the corner.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I met up with a few friends earlier and also checked a total of 6 brand new Galaxy Notes. Suffice to say that we each all had screen related issues ( lines/blotches/bad greys/poor black levels/spotty blacks/grainy screen/yellowish whites) aside from the spotty blacks all the other issues can be seen with normal use our standards are not high but was build up with the absolutely flawless screen on the galaxy s1.

My refund is coming up next week or so and after seeing 6 brand new units, I might not repurchase the Galaxy Note anymore unless I see one with a flawless screen and samsung has addressed this black clipping issue, I've only seen a small sample but all of them that cuts off at 4 on the gammatest shows the worst from of clipping+colorbanding+violet/blueboxing on video play back, while those that dim properly (like on the image attached) only have issues when it needs to smoothly transition to black, which is acceptable but not worth the $700 till it gets fixed.

Hi SAlmighty are you also from india??? " my refund has been approved and is now being processed" is it means the service center agreed to give you the refund ?? they have told me the same and requested to wait for 15 days to get the cheque.(it's my first time when i'm getting the refund so i'm novice here).

not really, in my country to get a refund, is like mission impossible. My country samsung service center guys can reflash original software and if it wont help they will say that the phone had contact with water and it is non warranty phone ;/

after getting my money back hopefully i'll say the same.Lets see when they will give me the cheque.

in my city only one samsung center :/
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
Yes, it takes 15 days for the cheque to process. And depending on the bank, it takes a few day more for the money to show on your account. You should have been required to sign some documents if the refund was an official decision. ;)

Well, I would say Samsung knows that there are a few bright consumers out there and want what they paid for. If the demands by these bright consumers are not met, it would be court-time for Samsung, thus jeopardizing the future of this corporation. Everybody will come to know that problems exist with the Note, and people will demand their money back and not think twice, but thrice, to purchase Samsung Products again. I don't know if customer satisfaction is something Samsung will maintain in the near future, its very similar to quality control, but at least we have our rights for now and we have every will to get what we want. :mad:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] mateusm:
Dang, I was gonna buy a note this week... now idk. :(

Judging by the looks of some of the photos uploaded in this thread, it looks very much like a hardware issue. I'm still going to the store later in the week to check out how the devices are doing in my country.

Best of luck for those trying to refund and etc.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] b00gieMan_droid:
about the "moderat-rusty nails", that damn video show black clipping @ 0.20 secs on MY NEXUS ONE, On friend's LED MONITOR, LED TV, My computer HD Monitor, my friend's GALAXY S 2, Friend's GALAXY NOTE... this means that its the video not the damn GALAXY NOTE!

I saw on each devices again and again, the black clipping shows not only @ 0.20-0.22, but its at many points in the video, same on all devices..!!!

Other things like color banding and shadow seems like its coz of stupid Samsung's stock ROM which i am assuming that its the same low resolution and low color depth ROM colors taht's been used on Samsung's older low resolution phones and they are messing up with Note coz of its sheer size and 1280x800 HD display.

Guys in here, please try a custom rom and see if u still see thos banding issues on custom ROMs.

EDIT: Am sure that this small nitpicked issues will be resolved in TouchWiz 5.0 with ICS coz then they will be releasing many more HD sAMOLED Displays.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Yes,I can see it on both my notebooks too but if the gamma is set correctly,the "clipping" is not very noticeable.You have to look really hard for it.

On the GNote,the clipping is very noticeable due to the high gamma setting.If you have the ability to alter the gamma on your PC or notebook,play around with the settings and you will see what I mean.

I think the issue is a mixture of gamma and video source as some videos don't clip as bad as others.
