[Q] [???] WTF with the amoled matrix??? - Galaxy Note GT-N7000 General

Prerequisites for the test:
1. Wallpaper with black background;
2. Screen Filter from Market with 6-8% of brightness;
3. Camera shoot settings: ISO 100, 30 sec, manual focus.
Result:

There have been reports of black spots when displaying dark grey or black backgrounds. It's a phenomenon that's been around on amoled displays for a couple years. Not a big deal unless you do a lot of black and dark grey viewing.

I have no idea if that is supposed to be normal with the SuperAMOLED screens but when I had my Galaxy S1, I really had to look hard in a totally dark room to even see a slight faint glow.. it was extremely uniform and no black blotches, same goes for my Samsung Wave.
Incoming wall of text-
The Galaxy S2 was a combo breaker though, I had a total of 3 replacements the first one really had great blacks.. in a totally dark room I had to put the phone THAT close to my face even to see the faint glow, but that screen had some yellow tinting, 2nd and 3rd replacement had random blotch spots and the 3rd one was even noticeable even with minimal ambient light.
My Galaxy Note also has those blotches but they are very very small and I cant see them with my normal movie viewing in my room before I sleep, Try to have it replaced if it bothers you, it looks like an eyesore for me but dont let my expectations be yours.

I think they all do this. I see this every now and then in a very dark room.
I guess try not to have a seizure and have your eyes lock open for 30 seconds, and you'll be alright. jk

I've had this on SGS2 , now I have it on my Note
It's not a big deal for me , I saw these spots twice in a month,so it doesn't bather me , the screen looks amazing all the time

I dont know if all the notes are affected with this but my Galaxy S1, Samsung Wave and first Galaxy S2 didnt have this issue. Absolutely deep dark blacks as if they were really off with extremely minimal but uniform glow. I was devastated to see it on my 2nd and 3rd S2.
It maybe normal for some but since my expectation was set high with the Galaxy S1 and Wave its not normal for me but on my note its so minimal that its not worth the risk of replacement.
But you know if all of us would be vigilant in not accepting these things, samsung might just step up the quality control with this but IDK if its worth the inconvenience.

i'm kind of feeling the same way. my galaxy s doesn't have any of these blotches or glowing blacks. i bought and returned a galaxy s2 LTE because of this reason. just purchased a note and am awaiting shipment. I hope it is something i can live with. i watch a lot of videos / netflix before falling asleep, and that is when it is really noticeable.

Well if you had an LCD the backlight glow would be much more than that is.
Go look at an iPad in the dark with a "black" screen, then come back and complain about the Note (remember, everything Apple does is the best of the best).
Yes mine glows too, and I have a 2 inch dark line by the left edge seen in pitch dark room too. The larger these panels get, the harder they are to get "perfect". If they only released truly perfect panels, the Note would probably cost $1600 as the reject rate would be super high.
MyZune HD had this too (that is the first time I "freaked out" about it, then realized that most do this and it isn't too bad when displaying something). I just chalk it up to OLED tech being kind of new still. As long as it isn't noticeable in images, and as long as I don't have any bad pixels I don't freak out about it anymore.

Have it replaced if it bothers you, if you decide to just live with it then it means your OK with samsung selling you faulty or out of spec products.

True the bigger the panels the more defects it can possibly have, hence the 4" SGS1 and 3.5" Samsung wave never had these issues.
But we also have to consider that the blotches are out of spec and considering that the screen is one of the best selling feature on the screen but its also its biggest weakness to have such issues even how minor it is.

It's a tough line to draw, isn't it?
Part of the problem here is the Note is a new device, and I do hope enough people accept its quirks for it to succeed. I'm not asking anyone too, but I do hope they do. If there was a viable alternative then I would be more willing to be picky. But as I said in another thread, choose what device gives you the overall best experience, and live with its deficiencies.
Currently the note is that device for me, so I can ignore stuff like this. (helps that it doesn't happen much.). If this issue is really detracting from your enjoyment - then by all means, return it.
But the main point of my post was - this is a common problem, so I wouldn't return it expecting to get a better one.

Acceptance is a double edge sword, we accept the quirks at the same time Samsung can just slack on QC.

Not everyone has the same level of expectation though, on my end Im just luck the black spots are extremely small that Id have to really look for them.

I think the important thing here is the extremely low Screen Filter settings the OP used. I don't think you can really pick fault with a device when you're using it at a brightness well below normal use or the manufacturers intentions.

Light blobs on black screen

Anyone else notice lighter blobs on their screen when a black app is loaded?
Try the night clock and tell me if you see any.
I use my phone as a clock at night and I just got this today and wow is it noticeable.

I also had that issue on my first unit, I had it replaced.
A quite bellow summarizes all the screen issues on the S2.
BarryH_GEG said:
There's really two separate issues that sometimes overlap:
1) The left side banding which appears along with a yellow tint either under certain conditions or, to some, in everyday use. This would seem to be a design issue as, to date, it shows up on every single phone produced.
2) Screen QC issues which include: 1) suction cup circles from production, 2) fingerprints on the inside of the display, 3) dead pixels, 4) vertical or horizontal lines, 5) ghosting, 6) white or black blotches, and 7) wide swings in color temperature.
There's no doubt the QC issues are probably vexing to Samsung. Based on the sheer quantity of displays they need to produce to satisfy demand they're either intentionally allowing displays to go out that shouldn't or are finding out from customers that bad displays got passed QC. Considering the large number of phones sold it's hard to guess the bad:good ratio but it would appear its larger than appropriate. And it doesn't appear to be getting better as newer builds seem to have the same issues as early builds. So banding may be forever but swapping phones may definitely help with the other issues.
I do think that adding the QC issues on top of the banding issue does compound it on some phones. That could certainly explain why some of us are happy and others aren't. There's still a lot of subjectivity at play so it will always be hard to say if what's acceptable to some is unacceptable to others. But with all the phones sold, you'd still think if more than a few percent had serious screen issues there would be a bigger audience for this thread and the issue(s) would have become more prominent on its own. I'd like to think things will get better but production demands may continue to allow QC issues to occur at higher than normal rates. Something that's frustrating for everyone - including Samsung.
Someone said something about the technology being flawed. Here's two links to stories where Apple was/is trying to get SAMOLED for their products. To me, it just helps reinforce that the benefits (color, contrast, viewing angles) still outweigh the downsides (screen life, burn in, inconsistency). And I'm sure Apple's engineers fully reviewed both the upside and downside before considering SAMOLED so it's still kind of a vote of confidence in the technology.

Thanks!
I'll have to get back there to have it replaced.

I've had it replaced 3 times now, I'm on my 4th unit. I can exchange one more time before I have to send it out for repairs.
I'll wait for them to get a new shipment in with different serial numbers (all the ones i've had start with the same 4 digits) and hope i get clean ones.
I called Samsung and the rep i spoke to told me that they have not heard of this issue.
Well they have 3 units in their back room with this issue so they will see it.
I think I will have to take a long-exposure photo to show them what the issue is.
Fingers crossed the next shipment is clear.

I've seen this isseu quite often when I had my phone exchanged mainly for a different screen defect, just be warned though since you had so many exchanges some people here might not actually believe that you went through 4 phones because 6Million phones sold and all that jazz.
Good idea that you decided to wait for another shipping, maybe you can even get a refund and just buy from another store that has good stocks?
I don't care what other believe or not. If they want to see my receipt plus the 2 exchange receipts I have here in this bag beside me I'll send them a picture.
Regardless, I must be one of the few people who have this screen problem AND use the phone as a night clock.
I am posting this for information to anyone who also has experienced or may wonder if their phone also has this issue.
If you dont have it, GREAT! I wish I had your phone.
(ps, this isnt a rant, just want this to be over)
I have zero issues with my screen; no ghosting, yellow/pink tint, light bolbs etc.
but no one believes me

Someone else in Canada (Toronto) went through five phones because of tinting issues with the display. He too exchanged them back-to-back from the same store. If you've been going to the same store, and there was a run of bad displays, all the phones built in sequence could be effected. Can't you go to a different store and exchange it there?
Have the same problem, its like blobs/smudges that are lighter black/greyish. Not an even black color.
Its best noticeable in a dark room without any other light, not even the light of the touch buttons or top bar active (so your eyes are adjusted to seeing in the dark). Using this image I can see it clearly. Auto adjust screen power doesn't influence it.
I think we all may have blobs to varying degrees. The other day I looked at my screen in bright sunlight with polarized sunglasses on. It made the screen look black but you could clearly see random beige blotches all over it. In normal use I think my screen is as close to perfect as there is and when looking at a black background in the dark I don't see blobs or blotches. The "O" in AMOLED stands for organic which means alive. Maybe what we're seeing is a by product of the technology.

You got it too!
Well, i'm glad I'm not alone sorry that you have it too.
Hopefully I will get a call from the store when the new shipment comes in and the issue will go away.
I tried going to another store and was told DOA's could not be exchanged at other stores that they had to go back to the store it was purchased at.
It is likely that all phones at Bell at all the stores at the same time may well come from the same batch.
I can wait over the weekend. I bought it on the 1st so still have most of my 30 day period to do the exchange. after that its repairs only. trying to avoid that.
I tried to get back the first one I had as it didn't have it as bad as all the subsequent ones I've had. Once a phone is marked DOA it can not be resold until it has been reconditioned and put back through the system. Understandable.

I agree and I can accept some imperfections but I'd like to get as close to "perfect" as I can seeing that I had it in the beginning (WHY didnt I keep the first one?!)

Well good you don't see any blobs or perhaps you are suffering from a certain degree of Nyctalopia. Sometimes a disorder is not bad, see no evil ... Nonetheless the O in AMOLED doesn't stand for alive, just for a chemical compound containing molecules with carbon.
I must add that two Galaxy S (i9000) models I have looked at don't have this issue, at all. The screens are fully and equally the same black tint/shade. Taking a picture to capture the problem has proven to be somewhat difficult, but this old camera probably isn't really anything to write home about these days.

OCD is also a recognized disorder in which the pursuit of perfection overtakes one's life. If I had problems with my phone I'd have no problem sharing them. I've posted tons of pics of my phone in the dark, in the light, on grey, showing apps, and at every brightness level between 0% and 100%. I'm not going to apologize because I have a decent screen. Though I do sympathize with those that aren't satisfied for whatever the reason.

I'm glad that all i have are these splotches on the screen in the darkness. it is not viewable at any other time and all other functions of the phone are perfect.
I can live with the splotches if i have to but would prefer to not. I'll exchange one more time and leave it.

I'm sure I'm not special. If you look at the low level of participation in the display threads either people have low standards or the majority of phones are like mine. Even within the display threads, 50% of the posts are by the same dozen or so people. In the other Canadian display thread a bunch of people from Toronto posted they had no problems. So keep spinning the wheel, you're bound to get lucky.

Obsessive–compulsive disorder is not how you describe it, perfectionism is. Some more of this perfectionism for a company like Samsung would not be bad at all.
It was not meant to be taken seriously anyway (hence the smiley). Albeit a joke, people whom suffer from night blindness will of course not see this particular issue though.
While I believe I did not post in the other display problem threads. I do have yellow tint and pink/blueish shade from all angles except from front. Which of course doesn't make it sound like a decent and proper SAMOLED+ display at all. Since I have a Galaxy S that doesn't exhibit these problems, it of course makes me a little disappointed.

I can not exchange my phone, probably because it was included for "free" with a Vodafone plan, even though I just have it a couple of days. The shop implied I could sent it in for repair but I am reluctant to do that for various reasons.

Not all phones are affected with the same assortment of issues but I find it hard to believe that your phone does not have any ghosting, its an limitation on the SAMOLED+, Im not saying your lying but I dont believe that claim either. For the yellow banding on the left side user to user and phone to phone subjective.

One of my thoughts also point to that a lot of S2 owners are first time users of SAMOLED screens, hence they dont know what to expect or have an entire low level of expectations. The S2 is my 3rd phone with a SAMOLED based technology and pretty much the expectation should be higher than the first generation SAMOLED right?
But all people say that these defects are expected are we are the minority as millions and millions of phones getting sold but theres no "internet media coverage" about it and they start bringing in other phones as a comparison when the only comparison needed is the previous generation SAMOLED.
I was initially very disappointed on this until I had my phone exchanged (Had to sort out over a dozen phones) and also XXKGx firmware alleviated the yellow banding, right now Im happy with what I got but I can be happier if the quality on the SAMOLED+ surpassed the first generation, The regular SAMOLED is superior in every way even if it was pentile. I just gotta hope for the best when the SGS3 and SAMOLED HD comes out.

This could also be a possible reason why Samsung has never said anything about the display issues on the S2, a lot of shops are refusing exchanges and sending customers to the service center and have repairs instead, probably Samsung has informed its retail channel that they will be replacing deadpixels only anything should be dealt with by the retailer.. well just a conspiracy theory =)

I've had it with this phone...

My first Galaxy Note had dead pixels, burn-in effects (don't know what you call them but there are pictures in the link below). The second one I got as a replacement had much more burn-in effects than the first one. The third Galaxy Note had burn-in effects but not as much as the first two, but the gyroscope isn't working on third one, yes I've calibrated it like a thousand times. All of these phones had the burn-in effects out of the box, so it wasn't I who was overheating the phones screen or something like that...
There were also other minor problems (with all three phones) like bad audio quality, bad Bluetooth connectivity, minor lagging and small blocks appearing when watching videos (yes, even of high quality videos) which doesn't appear on any other phone I've had.
I've never had any of these problems with another phone. I've mainly used Sony Ericsson and Apple phones. Off topic, or maybe not.. I also bought an Samsung Galaxy S2 for my girlfriend and it too had burn-in effects and a burnt in status bar (nothing she really cared about, I take it as does most of the people who have it), so it's not just the Galaxy Note suffering from this issue.
Now I'm here, with my third fricking defective Galaxy Note, really pissed off at these issues. If one pays ca. 500+ euros for a quality phone made by the "best" phone company in the world one doesn't expect to have these issues.
I will try to solve this by contacting Samsung. But I would ask of other owners of the Galaxy Note to do the following test on their phones and post a result.
Download the app:
1. Dead Pixel Detect and Fix
2. Start with choosing the colors white and grey
3. Within the app, go to settings, set brightness to lowest.
4. Be in a dark room and look for these burn in effects I'm talking about (dark vertical and horizontal lines + smudges).
Take a picture of the screen with another camera, taking a picture with the phone itself won't show these issues as it's not software issue but a hardware issue.
These were my results with the first two phones I bought:

Thank you.
Looking at your pictures they do look very bad, I cant even tell if that is supposed to be a white or grey rendering on the screen but thats an obvious defect.
Did you get your note from a retail store?
I've also had several replacements with my S2 and I ended up getting a refund.
IMHO, part of the cause of this really low quality control is not by samsung but from other users who accept obvious defects to be normal or tolerable, sure its gonna be a PIA to have it exchanged upto more then a dozen times but since a great majority of them are just accepting it so samsung is giving us sup par quality control.
Can't remember if the colors were white or grey on the first picture, but they were definitely the same on both phones!
I bought the first two phones from amazon.de, I got my money back from amazon.de. And I got my third galaxy note yesterday from handyshop.de...

Might be. It seems like the people who are buying Samsung phones doesn't know what quality is, so they just keep the phones and praise the company and the model.

They know what quality is, they just accept the defects as normal. For me I find it hard to accept some of the screen defects when I never faced this issue with first 2 SAMOLED devices. I guess its the flawless screens I had with my first 2 devices placed me in such high expectations especially on the SAMOLED Plus.
I'll try to see if I can also have mine replaced, the only issue I have is the faint horizontal lines, can be seen even when browsing. No effort needed to see it.

Sorry to read of your difficulties, but you do realize their are plenty of Sony and Apple owners with similar problems, right? You've just been lucky until now.
I have a SGS2 and My screen is perfect! Tried the app that is mentioned and all colors are perfect! Maybe there is a bad batch of Super AMOLED HD panels floating around. Don't know but I have never seen SAMOLED screen in such a bad shape! And I've seen a lot! Have somebody heard of Nexus Prime having this issues too?
Sorry, but may you take one picture and draw a circle around the defects? I'm honest: I don't see the banding/burn-in effects on your pictures, nor any dead pixels.
All I see is a poorly made photo, which isn't really sharp, sometimes shaken, and has a lot of grain, probably taken with a low cost camera at a too low brightness the camera isn't able to work with.
If I run the program on my HTC Desire (AMOLED) and on the Samsung Galaxy Note (Super AMOLED) I can't spot an failure. I see a minor burn-in in the notification area, which has nothing to do with quality control but rather it's a display technology limitation.
Else I can't spot any defects, no burn-ins, banding, ...
Just as I don't see this on your pictures, except a lot of grain caused by your camera.
One thing is obvious, that at the lowest brightness setting in a dark room, displaying a dark color, taken with a high exposure time, one can spot a difference in color reproduction between both models. But this is no failure at all, because the difference is minor and the frame conditions stupid. And you probably wouldn't be able to tell a difference without a direct comparison at such artificial frame conditions. And the question is, do other manufacturers allow such a low brightness? Do others have such an evenly lit display?
I really don't see any failure with your models.
So please, make a good photo, with a good DSLR, which is a necessity at such low lights, mounted on a tripod, and then draw a circle around the dead pixels, the banding and the burn-in.

Sorry, but may you take one picture and draw a circle around the defects? I'm honest: I don't see the banding/burn-in effects on your pictures, nor any dead pixels.
All I see is a poorly made photo, which isn't really sharp, sometimes shaken, and has a lot of grain, probably taken with a low cost camera at a too low brightness the camera isn't able to work with.
If I run the program on my HTC Desire (AMOLED) and on the Samsung Galaxy Note (Super AMOLED) I can't spot an failure. I see a minor burn-in in the notification area, which has nothing to do with quality control but rather it's a display technology limitation.
Else I can't spot any defects, no burn-ins, banding, ...
Just as I don't see this on your pictures, except a lot of grain caused by your camera.

Never heard of any screen problems with Apple and SE, (not saying it doesn't exist) but yes I might have been lucky until now. But what are the odds, 3 gnotes in a row (+ my gf's S2), more or less. It's like all my good luck has secretly been accumulating a lot of bad luck lol. Yeah but I can live with this third one, it's not as bad as the first two. But the problem is the gyroscope. It works randomly.
This is a major feature of recent Samsung Amoled actually. People have been complaining of screen problem for Galaxy SII, Nexus and Note.
They might not want to make the same mistake with their new 2560x1600 ICS tablet.
I've been interested in other phones that uses Sharp's ASV panel.

Strange that you compare OLED displays with LCD. No LCD on earth has a black as OLED, so if you compare OLED next to LCD at such sub-opimatl conditions you'll notice, that LCD won't even go as dark.
And never had any sort of backlight bleed? Just do a google search 'iPhone 4 backlight bleed' which are issues which are obvious.
I still can't see the issues on your pictures. I see artifacts and errors caused by the poor digital camera you used, just as buk_grudziadz nicely compared, thank you buk_grudziadz. But I don't see display failures and you don't seem to be able to show me them, else you would have done it already, or?

Well your whole comment seemed more like an insult than any help. How can't you see the issues on the screen? There is only one color on the whole screen, do you think it looks even? You and your friend are the first two people to complain about the photo quality, I'm not the best photographer and I don't know much about how to take good photos, but the problem is very visible. There are black lines, horizontal and vertical and dark smudges. I wish I knew how to take better pictures, even if I did know I don't have the phones since I returned them.
I have the third one left, but it's not that bad as the first two. If you want I can take a photo of it with a galaxy S2.
maybe your phones have the issues, I don't know and I can't tell it.
It's impossible to tell if the photos were taken with a smartphone camera, which adds that much noise that any slight color failures get overshadowed.
Just as with the pictures buk_grudziadz has taken. The display in the photo taken with the DSLR looks perfect, which it is. The same display taken with the Desire Z looks wrong. It has artifacts, color distortion (green and red) seems to have banding, and is grainy (noise), but it isn't. The photo is totally misleading, just as yours are.
So by looking at your pictures your display looks wrong, but not because of the display, but because of the poor camera quality. You can't do better photos with a smartphone camera, even with a point and shot camera it's difficult, you need a DSLR with a large CCD/CMOS sensor and good optics to take reasonable pictures at such a low light. If you don't have one, ask a friend. But the photos you posted are useless, sorry.
Just take a look at the two photos buk_grudziadz posted and tell me, does the display in the photo taken with the Desire Z look faulty or good?
I think your problem is that you are a screen nazi. No screen is perfect. I myself found a dead pixel with your app that i never noticed.
BTW to my knowledge AMOLED displays don't have backlight and the pixels themselves emit light right? So if I'm right, how is it possible to even burn the image of the statusbar when Samsung uses black theme? black means pixels off. How can an image be burned in the display that way?
@UpSpin
They did have those issues and I don't care if you think they "maybe" had those issues. Who the hell do you think you are coming here and being rude, questioning the validity of the issues I've had. I've been through hell with these phones complaining, sending them back, waiting for new ones and loosing money. You are not helping by complaining about the photos.
Do you really think someone would waste their free time on lying about some frickin issues on cellphones? The first person to answer this thread clearly could see them, and I wouldn't post those photos if they didn't look like EXACTLY what I could see with my own eyes. I posted those photos here a long time ago in another thread and nobody complained about the quality. They all saw the issues, many of them had the issues too.
I'm on my third galaxy note and it does have these issues, but luckily not as visible as the first two. When using the same camera I used before and the same settings on the new galaxy note, the problems are barely visible. It doesn't give the new phone some banding or artifacts.
Now these issues was mostly visible when using the lowest screen brightness with grey or white colors (picture yourself reading a book or browsing the internet). It was really annoying and a quality phone from the best phone company shouldn't have those issues.

Thank you for your comment, it really helped me. Seriously though, my problem is that I care about quality, clearly some people don't judging by your comment. If I pay 500+ euros for a phone with an amazing 5.3" AMOLED HD screen from the best phone company in the world, I don't expect to have problems out of the box. And if you did read my first post you would see that the third galaxy note I have has those issues but not as much as the first two and I am FINE with it. I was just pointing out that all of the gnotes I received had those issues, more or less and I wanted to know if other people had those too.

Screen disappointment?? Anyone else?

Hi guys!
First off I wanna say I love my Note!! I have the Korea version as well.
Anyway, I still have my Galaxy S I which I ended the contract to get a Note.
I have to say as far as the "blacks" are concerned, the Galaxy S I wins hands down and also the text/color is sharper and even brighter than the Note.
I tried to take side by side photos but this was the best I could do to show the difference. Both phones are at max. brightness

The pics do not do justice. In person there is a real difference. Even the capacitive lights on the bottom are brighter and whiter.
Not a big deal though when my Gaalaxy S isnt being compared to the Note. Just bothers me a bit personally
Thanks!!
Its becoz of the resolution . Galaxy Has 480 x 800 and in Note 1280 x 800, their is a lot of difference in these too models. anyway Supercurio is working on color issues on Note. lets Hope for better result.

After installing Screen Adjuster free from the market ..I just upped the red a fraction [+3] to get rid of the slightest green tinge to my screen.
Then installed Voodoo Screen from the Market and set it to Native Mode... this has fixed 90% of the banding issue on my Note.
Now the screen is beautiful and can hardly fault it.

Coming from a galaxy s with a perfect screen i have to agree that the black levels on the note is not as good and yes picture quality on the first generation screen is better even if its just plain pentile and non hd resolution.
People who started with the galaxy note are easily blown away but those who started with the first gen need more to be pleased. I also started a thread about this before and got the same results on the black levels.. im hoping that hd samoled plus can redeem the samoled family.
I think it is an amazing screen!!! I love it, about it being less bright, god I think the note is too bright. I never have it on full brightness unless its really bright sunshine, and in the dark I wish it would go darker, but it won't.
And the black levels!!!(I'm sick of hearing about this in the this forum) some people are so anal about this, I mean I can only just about tell that the screen is on, on a full black screen when I'm in a pitch black room, which I did to test the blacks. So 99% of the time you can't tell, and even in a pitch black room as soon as theres a pixel of light on the screen your eyes adjust and the blacks look black again. Secondly how many of you that are bothered about this, actually sit in the cinema or watch tv or when on the computer, say oh my good the blacks aren't quiet black. I can pretty much guarantee that all the screens in your life aren't LED so why bother so much about it on your phone?
I also love the screen. No disappointment at all!
Would you rather have 480x800!?
This is brand new technology! It pushes the limits of what can be done at consumer price.
And people are complaining!? WTF!
edit: I owned a SGS1, but I like the Note's screen way more. Much sharper.
Although I must say I'm not experiencing the issues I read about on the forum.

I worked a few years in an industrial R&D department and designed new products, but we NEVER would have dared to release a product with such massive quality fluctuations (problems) onto a mass market! Especially when the screen is THE major unique selling argument!
Fine that YOUR screen is fine for YOU, but sorry, your arguments are pure ignorance! You do NOT have this issues, fine, then why judge about their seriousness??

Jeez, dont buy a samsung nexus then because that thing is a mess. Signal fluctuates so badly that its kinda funny. Fake screen size (the android buttons are actually on the bottom of the screen, reducing the screen size to the razr. The sound is a joke, the battery useless. Match that with no sd card slot no hdmi and the headphone jack at the bottom of the phone and youve got a 600$ flop.
I bought it for my 12 year old and even he doesnt want it. He wants me to bring it back and get a razr....
BTW, i have a bad s pen and the trademark samsung pink hue in the middle of my camera but asude from that, i love my note. When i saw it in youtube early 2011 i knew it would become my daily phone web surfer.
I wish for the same phone with S amoled PLUS, volume and sleep buttons not across from each ither, no pink in camera, mute button (like iphone) and the sane type of notification light as on the samsung nexus, micro hdmi out and quad core
try the free wallpaper called "no wallpaper" by simplicity apps. The blacks that you see with that wallpaper are amazing and it is free. i often use my phone at night when my child is sleeping, so lights are off and dark and see pitch black screen.
have 2 htc desires at home with amoled screens and the note screen is way better than that. have seen SGS and SGS2 screens and the note is definetely much better than that.
also try the wallpaper (free and paid versions) of KF Flames or KF Flames Donation by kittehface software. the blacks on that are also awesome with equally awesome flame effects. prefer the stock setting than variations possible with paid version but bought paid version just to support developer as liked free version.
the screen on even the sgs2 is no comparison to the one on the note. is your phone stock version or is having different roms affecting the display?
ICS should sort out most issues as its 32bit colour .... (or it could be 24 bit not 100 percent) ,,,
no wallpaper works a treat ... also lowering red to 3
still some apps which are lower density look like they have lines on .. but if you take screen shot they are still there when looking on pc so its the app not the phone
this phone rocks ... never ever going back to the half eaten apple ....

Where in my post am I "judging" about "their" seriousness?
If you find the screen their "major unique selling argument", why did you buy it before doing research on the screen?
If you are so worked up about the screen, why don't you get a replacement or trade it for a different phone?
Why do you point your frustration at someone who bought a phone he likes?
Because you bought a phone that you do not like?
Really, if you are so pissed off that you have to enter a forum discussion this angry. You should return the phone.
If you worked in a research and design department you must be a smart guy. You know getting angry won't get us anywhere.

The blacks on my old S2 is way deeper than the one in the Note.
Disappointing for sure.
But i'll take sharper screen over deeper blacks any day.
Well I was the proud owner of two notes this week, first one had a screen which used to tint between pink and green, so I got Amazon to send a replacement, which came today.
Alas this one isn't rendering the blacks properly and makes Black & White photos and videos look awful, pity as I'm a photographer and wanted to show client photos on the note (First note rendered Blacks great, just the white balance kept going off every odd second or so).
So two notes being returned, not taking the risk again.

I'm not sure how the black levels are perceivably different from one OLED screen to another, whether it's AMOLED, SAMOLED, SAMOLED Plus, or HD SAMOLED.
I mean, think about it...
All OLED displays are actively lit, which means that each pixel is its own source of light as opposed to being, essentially, active colour filters for a backlight, like on an LCD.
Let's go ahead an use 24-bit colour for the following example:
Basically, each pixel is able to register 256 levels of intensity per colour, which is represented by 8 bits per colour. And since you have three colours (Red, Green, and Blue), that's 8 bits times 3, hence 24-bit.
In the case of an LCD, where each pixel is essentially a filter, blocking or allowing backlight through, a bit value of 0 for any particular colour would mean fully blocking light, and a bit value of 255 would mean fully allowing as much light through as possible.
However, since the backlight in an LCD is always on, regardless of the image, the front panel isn't always able to completely block all the light, even on a completely black image. That's why you're still able to see a little bit of bleed-through, even on the best LCD's.
With any kind of OLED display technology, this is not the case however. On an OLED display, each pixel is essentially a microscopic cluster of light emitting diodes, and since each pixel produces its own light, there is no backlight whatsoever. Thus, on an OLED display, a 255 bit value for a given colour means full intensity, and a bit value of 0 simply means "off."
Q.E.D. on any kind of OLED display, true black is truly black in the same sense that when a light bulb is turned off, it's completely off.
So, if you're perceiving a difference in the black levels between respective OLED devices, it could be simply that you're not viewing a truly black image. The image might contain pixel bit values close to 0, but not actually 0.

Screen feedbacks/issues

For the current owners, especially for those who are 'extremely' particular about the screen, do you guys any screen related issues?
I've been with the Galaxy S1 and S8500, both devices used the first generation SAMOLED screen and I never had any screen related issues on both devices but as of late there's been a lot of screen issues ( mostly quality control related ) on the Galaxy S2, Galaxy Note and Galaxy Nexus..
To name a few:
- faint but visible horizontal/vertical lines visible on white/grey images
- green/blue color tint when the device is tilted with in just a few degree's
- uneven screen brightness
- suction cup rings
- blotchy/spotty blacks, you can see darker or brighter spots when the screen is displaying an entire black image - All Tab7.7's have spotty blacks, if anyone has a screen w/o spotty blacks please post it up here, it would help a lot of people.
I owned a Galaxy S2, replaced for a total of 7 times all had different screen related issues and I decided to get a refund for and got the G-Note when It came out, already had 1 screen replacement which resolved the lines issue but other screen related issues took its place, still waiting for the 3rd screen replacement to arrive and also processing a refund if they are not able to fix it.
I plan to make the Tab7.7 as my primary media device ( please spare me the 'get a plasma tv defense' ) and a web browsing device so screen quality is very important to me and most of the time it will be used at 0-10% screen brightness in a dark room (bed room).
Using the Tab in a totally dark room is nothing considered as 'extreme conditions' just because not everyone has the same usage pattern does not translate to 'extreme conditions only' situation.
Id like to ask a very honest and objective feedback from the current owners, I also understand that as of now only a few have this device. Testing in a dark room or with minimal ambient light is preferred as reflections can really skew results.
For anyone also wanting to contribute check the following images on your Tab 7.7 and put it in full screen and see if there are any uneven shades,lines or anything to report about.
This thread will get more exposure as the Tab 7.7 is slowly rolled out around the world. I would like to restate that this is purely an objective thread and not the subjective 'i dont see it in normal use' because not everyone has the same normal usage. Its not to say that all of the Tab7.7 screens are defective but Id like to see how wide spread the issue is based on XDA-Developer members. Again people, objective and not subjective.
EDIT:
For now it seems that I've gotten enough feedback and expect the very same issues from the Galaxy S2, Need a huge amount of luck for the purchase on my end.
EDIT2:
We need someone who claims that their black screen output is very uniform and does not have any spots, so far nobody has posted yet but we do see claims but these claims are not enough, for the sake of research anyone with an screen with no blotches or spots on black post up.
EDIT3: (Feb 19 2012)
After checking out and screening a total of 15 units from different stores and different dates, I've managed to see only 2 units with 'acceptable' screens. I say acceptable because I am expecting the grey rendering to be as good as on the Galaxy S and S8500. I will be getting one tomorrow but it still has a visible darker top part and lighter bottom when rendering greys.
The very common issue I've seen is a visible thick vertical/horizontal lines on the screen when rendering greys and either a yellowish or greenish discoloration at the bottom and some reddish bleeding on the edges ( mostly top ) I dont think a screen that can render greys on the Tab7.7 exists for now but Im sure it will be possible 6-8 months down the road when screen production gets better.
Different shades of greys are my objective way of testing the screen quality as it easily cuts down the time needed to do so, if a certain screen passes my objective test I goto the subjective test, Load up Thumbkeyboard and use the split lay out with the ICS theme and observe if the shades on the letters from Q to P are the same, some screens that fail the objective test actually produce good results on the subjective test, while others really give out a very obvious discoloration, also all of my tests are done with 0% brightness since thats the brightness i will be using 90% of the time, as the brightness ramps up these discolorations become less obvious.
EDIT4:
Anyone wanting to set here my suite of grey test images
http://www.mediafire.com/?hfxjz8nhymc4h4d
Crucial images are the grey-15 and grey-25, test in a room w/o any directly light or reflections from your face. 0-33% brightness.
EDIT5:
Why grey images, why all this specific settings that require planetary alignment and a virgin sacrifice, read on:-

I've had mine for almost a month, no burn-in issues, Ive been using the Tab almost in portrait mode and stopped using Honeybar just to see how fast the burn-in kicks in, nothing what so ever.
I cant judge if its visible in normal use or not, unlike others I dont assume how a screen issue looks like unless I've seen it or at least pictures of the issue, this has always been the source of many arguments in forums, people just assume all screens are created equally and just because they dont see the exact same issue on their end they actually become more aggressive and hateful and they tend to find the need to keep defending the product. What gives?
Companies always add a cost buffer to cover for returns and that is usually with upto 3 returns, but complacent people just accepting obivous defects are also the cause for this level of quality control since Samsung can now get away with it, especially that some people are false advocating that there are issues thats normal to AMOLED which is incorrect.
I havent used my Tab yet as an ebook reader so Im not exactly sure what they are experiencing but the pictures posted paint a clear picture, It can be annoying at times I suppose and when a product is marketed for its great screen and deep black levels, should anything less be expected? I mean personally coming from a Galaxy S which had none of the screen issues you've mentioned, the Tab7.7's screen should be expected to be better in every single aspect, right?
I've been quite active in this forum and I haven't seen anyone report multiple exchanges yet, I didnt even exchange my Tab yet.
I dont know who you are specifically referring to but I also use greys as my test images, let me give you a little more perspective incase you made a 'selective reading' in regards to this issue.
Grey colors easily allow you to check if your getting a quality screen or not, they can easily show those lines and discolorations with out the need for using multiple test images, they give you objective results especially when your buying the device but its not very conclusive since the store light will show a lot of reflection on the screen.
Testing at 0% brightness in low light environment is also ideal for an objective testing to avoid any reflections that you might see hiding these flaws, but if one exclusively uses the device in a very bright environment then this step can be skipped.
And this is the real world perspective:
This is the original grey image:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
and it should look close to that on the tablet.. For comparison, on my Galaxy S and my former Galaxy S2 can render this color perfectly.
not something like this:
one side is darker, visible lines, dots, circle marks.
You can argue that it only affects greys but it does affect a lot of things you see on the screen and to a certain extent like this:
and when we flip the tab over we get this:
Ignore the moire, notice that one side is darker than the other.
This is how the original frame looks like:
Sure not everyone uses the Tab7.7 as a media player, remember those visible rings and spots above? Check out the attached images.
This is because reviewers hype up the black levels saying its totally black and some internet articles say that AMOLED is in an 'off' state when displaying blacks which gives us the false information and relatively ruining expectations, my first samoled device was the S8500 (Wave) and the blacks were great, no blobs or spots and it had a very faint glow, that was the foundation of my expectation which was further reinforced by the Galaxy S that gave the same results. Others may have started with the Galaxy S2 and the expectations set by reviewers so they ended up returning their devices. On my end I returned it for the yellow tint, which the technician also confirmed that it was very visible and during that time there was nothing they can do.
Sorry for the wall of text but I felt that I should be explain this thoroughly as I am very affected by the screen issues and I am very vocal about it and it did get things done on my end.
TL;DR
Bottom line is, its a $700 device with its primary feature as the screen which is advertized,marketed and specified to have the most vivid, crisp, sharp and clear images. Others are reporting that they dont have any screen issues-what-so ever so why should someone else for settle anything less?

the 77 has same screen as the note... but it's brightness more even across the screen.. the only problem you will have is it's size... since you're coming from Note.. you might find it hard to justified it's size... like bringing it with u anywhere.? when jogging?
I am now using my old trusty ipad2 ... which I can type like a breeze...
like I said 77 has better amoled screen that early Notes...

Erm, wrong...
The Note is a PenTile display. The 7.7 is not.
The Note's PenTile arrangement uses 8 subpixels per 1 pixel.
The 7.7's SAMOLED Plus display uses 12 subpixels per 1 pixel.
I won't be brining it around for joggin of that sort, its gonna be my primary media device so it needs defect free from those random manufacturing faults.
It might be too early to ask this as probably the user count in xda is pretty small.
I'm returning one of this beacuse when reading in a dark room there are serval visible rings and spots darker than the rest of the screen.
You are only able to see it when you have a grey or black background and your eyes are adapted to the darkness.

This device probably isn't for you, yet.
I just got the 7.7 and have issues. The brightness is a bit brighter along one side, and I have the dark spot issue, this time in the form of dark circles, equally spaced (probably from the glass handling suction cups or something)
On the bright side, at least I don't have any bad pixels ;/
BTW a good app for testing is the simple "Advanced task manager" app, it has a dark screen near black and these blotches are visible with this even in a room with some light.
I used my galaxy tab 7.7 for almost a month and i must say , the dark circles are truly annoying especially when you watch movies with dark scenes in a dark room with low brightness.You can hide the dark circles by increasing the brightness but it is a simple waste of battery life and its really bright in dark room. I also noticed screen burn in for the wifi and battery icon, i used my 7.7 on zero brightness since day 1 and screen burn-in still persist after 3 weeks. Good way to see the dark circles is by simply turning off the tablet, the tablet will "glow" with the dark circles after the samsung logo is gone.

My old and new one have these rings. I'm guessing its glue or something bonding the screen to a backplate. Or an imprint of a backplate on the screen.
In any case I think this is not a problem or defect. You really must be in total darkness and viewing a black screen to see it. And even then its very hard to see.

Thanks for the heads up, It would seem that the darker spots are quite obvious since the screen is bigger, I also had those spots on some of my Galaxy S2 replacements and I found it very unacceptable and the same with my Note.
When I was testing at the store which had the usual store lighting one unit had several visible lines in greys while the other one only had 3 lines just in the middle.
For the uneven brightness on the screen, Im pretty sensitive to that.. when I saw the HC task bar in landscape mode I immediately noticed a difference in brightness but only 1 of the 2 exhibited the issue.
The screen burn-in is a concern as Im getting the same feedback from friends who bought the unit just last week!
I understand that not all screens have this issue but the chances of getting an out of spec screen might be pretty high, wish they brought back the same quality control when the Galaxy S initially came out, which had none of these issues what so ever.

It is a defect and a very bad one, also the visibility on this is not the same on all units. I have a suction up ring on my Galaxy Note which is visible at the 'service center lighting conditions' which the tech also saw the rings. Several pictures of this issue also posted on the various Galaxy S2 forums here in XDA under a well lit condition.

Seems like it until screen yields improve or I get a chance to get one w/o any of these out of spec issues.
No screen is perfect, not even the ipad screen.
Ihave a galaxy s2 and rememeber hearing all the burn in worries last year. Almost a year later now and i dont have any burn in.
The only issue ive noticed is that some pixels on oled can have a slightly differrent brightness than others due to the nature of oled. Yes my s2 has a tiny amount of pixels like that,
But you have to look at it at the wrong angle with the wrong amount of ambient light with the wrong colour on the screen to notice it.
Yes a larger screen is likely to have more issues but if it was an ips screen then we would no doubt all complain about backlight bleed.
My advice is stop looking for problems with it and enjoy your tablet otherwise you will never be happy with it !

Like what you said, no perfect screen but there are some screens that are made better, A year of usage with no burn-in is fantastic! Some are getting it as early 30days from purchase.

Well that depends on the usage, Im not pushing my own usage to anyone as I believe not everyone watches movies or browses the web on the tab7.7 with close to 0% brightness and in total darkness. My usage revolves on that so there are no special conditions on my end. I hope this is understandable.

I do not look for these issues intentionally and I see them with my normal usage, thats why I intend to research first before taking the plunge. But I understand I might have a higher standards that others but thats just me, I want to get the most of my purchase or not purchase at all.
Long story short, all the screen issues I've found on my Galaxy S2 was due to normal usage including the yellow tinting and darker spots which annoyed the heck out of me considering the cost of the device. On the Galaxy Note I've read about the all the screen related issues even on the video issue and still said to my self 'these things should not be noticeable in normal usage' but i was wrong. So this time Im taking it slowly but I already know what to expect. But I do understand what you are trying to say.
EDIT:
I dont want anyone to mistake this as a witch hunt, I just want to know what to expect, acceptance is easier when expectations are set.
Yes, there will never be 100% perfect screens. We'd all be constantly returning devices and not actually using them because of some "defect".
I've had my S2 since it first came out in May 2011. No problems with burn-in or colour shifts. I don't expect my 7.7 to have problems either. I'm not concerned that some "defect" will manifest itself under some extreme "only if I go looking " condition.
I'm enjoying using my S2, 7.7, and Transformer for what they are - mobile devices that provide communications, entertainment, and information.
Agreed I can also accept defects as long as I dont see them with my usage. Example between my SGS2 vs Galaxy Note which shared a common issue on the darker spots but it was more obvious on the SGS2 since it was a horrible pattern while on the Galaxy Note its tiny and multiple spots.
Every defect is different and we should not all assume that they are all acceptable to everyone.

May be for you it's an extreme situation, but in my case, I bought this tablet for reading ebooks at bed (among other things) and I use white text over black background, so I am in that "extreme situation" on a daily basis.
I also have a Galaxy Nexus and that screen also have one line and some dots, but since my usage pattern is not the same it don't bothers because I really dont see it. But in the case of the tablet, I had to convince myself that I had paid a big amount of money to receive a screen with what for me is a defect.
I was the owner of a Huawei Ideos S7-105 (I now miss it) and appart from the battery and several other small annoyances I was pretty happy with it, I paid 150€ for it so I got what I paid for, but the 7.7 costs 450€ so my level of exigence is higher.
Sad thing abot all of this is that the other tablet that could be an option (Xoom 2 8.2) seems to bee plently of issues as well.

This is always the case, people who dont have the same usage pattern nor with the same issue will never understand. But its been my understanding that this is already 'common' (but not normal) among amongst the hd samoled and samoled plus.

Yes the other alternatives that I've been looking are also riddled with issues, come to think of it only samsung has the least issues based on my research.
I've seen the concerns on other AMOLED devices Earlz mentions as well.
It's not a deal beaker but you may want to keep a LCD device around for reading at night.
No use exchanging numerous times hoping for a perfect screen.
Right now while AMOLED is a very dramatic screen tech
but it's not at its best with low brightness levels,
and certain test patterns / images reveal other side effects .
For reading in the dark a screen like the iPad 2's IPS LCD is probably a better choice.
It offers a very low brightness level with consistent results.
I think the key is to use AMOLED devices where they perform best,
at higher brightness levels during the day.
In that scenario if you hand a iPad 2 and AMOLED device
to the average person they will be floored with the AMOLED screen.
I don't have any issue on low brightness level.
I always operate my 7.7 at ~0-20% brightness.
Did anyone test the screen using the screen test apps? I tested mine and I have yellowish patch at the bottom part of the screen. It's only visible in dim grey. Luckily there is no dead pixel but my screen start to squeak a little when press at the bottom corner. The quality control is really bad. I'm waiting for a engineering revision before going for warranty claim. I must say I'm disappointed.

There's been a few reports from here and another forum that the screen seems to squeak or dislodge a bit on the bottom corner.
@SonicTab:
I went for an amoled screen beause it's suposed that when screen is black pixels are off and there should be no light emiting so in my case, when reading in the dark I should only see the text, and not a bluish black background as every other LCD based screen
@GOF007:
You are either lucky or do not use the tablet in the same conditions as I do. Did you test it viewing one of the pictures in the first post in a dark room?
I really hope my case where just bad luck and be given another tablet whitout those screen issues, or at least with something less annoying.

How to avoid screen aging?

I have my Galaxy Note for 10 weeks and after using it always with 100% brightness there are aging effects.
Specially at blue backgrounds, but also at white and gray I can see the home screen icons, the clock and some buttons from jelly defense (I played jelly defense 3 weeks daily 2 hours) shining darker. (you can see it on the photo)
Now my Galaxy Note is in service for screen changing.
But what can I do in the future to avoid this aging effects? 80% brightness, 90% brightness?
Samsung didn't know this problems (I'll not believe it).
Has anyone practical experience with this problem?
Typically Blue pixels age the fastest. So pick a warm/red background. Avoid 100% brightness. Use auto if possible. Avoid leave screen on for prolonged period. Avoid static text or icon on the screen for too long. Basically the same care you would do to a Plasma TV except even the plasma TV screen(around 80,000 to 100,000 hrs) lasts 10 times longer than the AMOLED screen (estimated around 10,000 to 20,000 hrs).
Looks like you've discovered amoleds dirty little secret. I avoid pixel burnout by using launchers that auto hide the notification bar as well as browsers that allow you to hide the navigation bar such as opera. Opera let's you browse in fill screen mode.
I often refrain from using apps that show static images for long periods of time. I try to use the browser for everything that can be done through the regular Web portal of a site.
There is no way of getting around static images in apps unless the Dev accounts for it. Some devs are aware of amoled burn out and have options to hide navigation bars.
Ultimately you have to be mindful of static images and make sure to either avoid them on your screen for prolonged periods of time or remember to rotate your screen.
This is why I'm not looking forward to virtual buttons on ICS. It will destroy amoled screens for sure. Hopefully Samsung will retain physical button(s)
10 weeks is a pretty short life time, My friend's Nexus One (1yr++) does not have the very slightest hint of screen aging why my the galaxy S2 that I used for just 2 months already had the AM/PM burned in.
Its normal for OLED screens to age but it should not be this fast, this is probably why apple is not looking into OLED screens as the quality and or lifespan could be problematic.
There are some manufacturing defects. Some screens are just fade faster than others. But in general, if you know how to take good care of your screen, it will last a long time. My old Galaxy S lasted over a year without any noticeable burn-in. My new Galaxy S2 has been 4 months w/o any problem.

like the part where you say "noticeable"
no matter how much you try to take care of it. It will happen. Its already there. (Depends to which degree)
My advice apart those ones about hiding the element that are always present.
Do not look for a screen burn in. Or do not look at the ****ty quality of the AMOLED. When you would look on for example on grey/ brown background easiest to spot when going to the marker you would notice the differences between the different parts of the screen. Its not perfectly even from the time its build. The color is displayed in different shades usually presenting itself in "lines".
Had my Note for 1 hour and I noticed it. Brand new.
But then again I know what to look for (proud owner of Galaxy S) and where to look for it.
I bought this device for the resolution and power. Not for the screen build quality
When I say 'noticeable', I meant to use screen test patterns. Last time I did that with my Galaxy S, I don't see any burn in with the test patterns at all. But I agree one should not purposfully sort after the burn in. It will always be there. But I also don't need live in panic. The great contrast of the screen (or infinite black) outweights any shortcomings it has. Side by side with an iPhone 4/4s, I simply can't stand the foggy looking screen of the LCD on iPhones. Every iPhone owners I encounter liked my SAMOLE screen better.

Hello fellow Galaxy S owner, This is the phone that brought up my standards and expectation for a SAMOLED device. I never saw any lines/uneven screen brightness and other garbage on my Galaxy S, even on greys. So this has brought up my expectation for a very high level which was crushed by the Galaxy Note's screen.

Good for you, I bought the device as a while package with the top concern about screen build quality and as an HD playback device which it does not meet the purpose
Just a quick tip I picked up from someone else on this site (I forget now who it was, sorry). Change your clock from 12 to 24 hour every now and then (and visa versa), it shifts all the icons along a little
This is both an interesting and depressing post to find. I was so excited to order my International Note soon, but now I'm super paranoid about screen aging. I've read so much conflicting information about it online, I don't even know what to believe anymore.

In terms of lifespan, LCDs still trump amoleds. That's a fact you'll have to live with.
No screen technology is perfect. SAMOLED for the moment has the problem that pixels decrease in brightness with ussage. So try to minimize the amount of light you get off the screen. That will also give you more battery life.
Try to use black backgrounds, and white text on black background if the application allows it. Of course if you spend 3 hours a day on a game with static icons and menus, that will wear some pixels more than others and you'll end up with something like the OP.
If you go looking for small variations of color, you're going to find them. But the superior brightness and contrast of a SAMOLED screen wins me over. Even when I know its effemeral and will degrade with time. But anyway, who keeps a phone more than 2 years?
Yeah, but I just found this information for the first time today, which is why I'm so depressed. I'm a digital artist so having a nice little on-the-go sketchpad has me super excited, but also worried because of the screen. Expansys tells me there's a 2 year warranty, but I don't know how that would work on an international phone if the screen goes bad...
---------- Post added at 02:46 PM ---------- Previous post was at 02:45 PM ----------
vcespon : Yeah, I normally keep the brightness on my Atrix down quite low anyways. The max brightness setting is *blindingly* bright. As for the 'who keeps a phone more then 2 years", I had my iphone 3gs for quite awhile thank you very much. That and if I spend 600-700 bucks on this baby I want it to last! If I get at the very least a year to a year and a half out of the screen I'll be somewhat happy, though closer to 2 would be better obviously. I wonder what the long-term outlook is for the life of these screens anyways. Does anyone know the mean-time-before-failure for them?
I would also try using black backgrounds or dark themes on as many apps as possible also. Like tapatalk or k9 for instance.

I think there are some references how long the pixels "live". You should google. Even though Samsung said that they used new materials to build the displays.
I can tell you one thing you get used to the inferior screen in time.(Few rants not and then) So I wouldn't worry about that. If it really fails you. Meaning someone else will notice something wrong on the screen no just you. Claim warranty
Also to pointing out. There is shor-term memory effect as well. I think I already posted some bad quality pics here about that from my SGS. > http://goo.gl/URYzm I do not remember if this is a burn it or just the memory effect. I think its the memory bla bla. Second pic is best.
Thanks for the information! I think I remembered someone saying that the short-term memory effect gets better over time as well. I'm mostly worried about the screen quality as I plan on doing a lot of sketching on it, which kind of sucks because it'll most likely be using a light-colored background then. :\ I wonder if the AT&T version will have the exact same screens or if they'll be a slightly updated version. I guess not considering AMOLED is still AMOLED.

You worry too much. And you do not even have that phone yet.
First of all not sure how its in your country, but here you can return in if you dont like it in a week I think.
Also if it becomes really apparent you really can go to a service center. I do not remember someone saying that samsung refused to change the screen.
Also I was ranting here already a year ago about the Galaxy S. I hate SAMOLED soo much since I got the SGS (18 months ago). I own an iPhone 4 and love retina and SLCD. And yet bought the Galaxy Note as well (despite the fact I knew how faulty it will be and how I will hate it )
Hey, I'm paranoid! I *really* get upset when I get a device that either isn't stable or has something wrong or defective about it. (Especially something that costs this much!) I'm in the US and am debating ordering through Expansys (USA), and I've heard they have I believe it was a 2 year warranty, but I have a feeling I'd have to send it to Expansys and have them take care of it if something went wrong. I can't see Samsung handling an international phone's repair in the US?
Aren't we strange with how we buy our gadgets? We know we will hate something and yet still buy it.

Here you can see my homescreen. There is already white text on black background.
But I can see the shadows of the big clock and all icons. The shadows are the white parts of the homescreen; for example the "S" of my S-Banking-App is very visible as a black shadow in all other apps with lighter background (Internet-Browser, ebook-Reader etc..).
And the homescreen is visible only for a few minutes, because when I want to use an app I directly start the app. I don't look so much time to the homescreen and my Galaxy Note goes after one minute in standby mode.
That means only 10 minutes/day homescreen with 100% brightness is enough to damage the screen visible after 10 weeks?
Okay, playing Jelly Defense 2 hours a day at 100% brightness is not so good, but the problem is not the time, because a few minutes looking to the homescreen has nearly the same aging effect.
