Different looking colors on 2 Incredibles?

I've got two incredibles side by side. Both are apparently listed as 'samsung_oled_display' with dmesg.
Right one has a purple tint that is more obvious on low brightness. But colors pop more, more contrast, saturation. On high brightness, whites and blacks look more right.
Left is slightly brighter on equal settings. Has a slight yellowy tint that's more noticeable on high brightness. But nowhere near as obvious as the purple tint.
Any thoughts? What looks more like the typical Incredible display people get?

it looks like maybe some of your LED backlights aren't as bright, or out completely. notice the shadow on the edges of the two sides? i don't notice a difference other than in one of the pictures, though. maybe do a better job taking pictures that aren't as shaky/blurry?

Best I could do, the incredible is my best camera and couldn't use it.
And which picture and which phone are you referring to?
I'm more just wondering why there's such a difference, and which one looks most accurate to what everyone else has?

3rd picture is the one i noticed it on. however, i wouldn't say....with the pictures i have in front of me....that either are too far off from what "everyone else has".
if you're that concerned about it, call VZW.

I had the same problem with a replacement, had to get a new refurb that didn't have a pink screen. Customer service is not aware of the issue, you might have to take it to a store and even the techs might not see it.

I did, this is my replacement ha... I'm not going to ask for a third, I'm just deciding which one is more like the rest.
And you don't think either are too far from what others have? Between the two there's a decent variation, Samsung amoled manufacturing just vary that much?

Only the first picture can I see a noticeable difference

I'm aware of people reporting a pinkish tint, but I didn't think its the same, since this comes off as purple to me.
And yea the first picture is the most obvious, but if you just look at the color difference in white,gray,black for the other 3 pictures, you can tell they're different tones/shades.
Honestly the left one is 'warmer' in tone and the right one is 'cooler'. Though right has better contrast and is overly saturated.
I think I'll probably keep the left one even though the right one is hands down amazing looking in full brightness, but looks all purplish in low, which is basically the setting I'll be using the phone most in.

Amoleds don't have background leds, the pixels emt the light themselves, as fat as I know

OLED doesnt use backlighting

Just pick the one that is easiest on your eyes. Yes colours will vary differently by batch (not usually by this much but really I can't tell a lot by these pictures). Personally to me overall one doesn't appear as bright as the other, so if they are using the same profiles, I'd take the bright one (but that's just me).

I think you are making a mountain out of mole hill. They both look ok, yes different but acceptable. It's a phone, you are not going to be doing Photoshop or high end video processing. If it bugs you, by all means take it back and ask for an exchange.

Oh I did, that's why I have two
And no I'm not, I can easily ask for a third. But like I said I won't.
I just thought I can get some expert opinions from others, -and- start a discussion.
There was a thread regarding evo's @ i6.photobucket. com/albums/y204/blu3g/002and003.jpg
that got some discussion.

They get dimmer over time, so yes the brighter one if in newer condition.
I'd prefer S-LCD to AMOLED anyday just for the fact that I dont have to worry about the screen dimming over time or burning in.

My girlfriends is like that. We both got our phones at the same time last June, same screens. She lost hers, and while her new one is AMOLED it's pinkish. It's only REALLY noticeable when the screen dims.

.... Seriously? You're complaining about a tint... A TINT!!!! the phone still works the same right? my replacement has the purplish tint too but who cares nobodies going to look at and say oh man your phone has a purplish tint what a fag lol

He was just asking a question because like most people on this forum, we are intrigued by how tech works, and we like to ask why do gadgets so the things they do, he wasn't complaining. Everybody who is saying that he needs to stop complaining needs to calm down, this isn't 4 chan. If you don't know why the screens are different colors, then there's no point in you commenting on this thread, especially if its to talk down to somebody under false accusations like some of you are.

i jsut got a replacement in the mail a week ago and i saw the same differences between my old one and new one. And i've heard of this happening to other people. Here is a thread all about this. I havent taken the time to read it but im sure it has the answer http://forum.xda-developers.com/showthread.php?t=656128
P.S. Garrett, you sound like a real douche

I've seen similar in my phone. I had to turn it in for a replacement and the first thing I noticed when I booted the new phone up was "hey, that white looks more pink than the original phone." Just to make sure I wasn't insane, I showed my wife the new phone and she immediately pops out "hey, that looks pink."
It's not bad enough that it's really a problem, just a little different, and the difference only really pops out at low brightness. I'm not going to re-return over it. At least this one doesn't have the spazzed out and possessed optical joystick that my first Inc did.

SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.

SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.
Hey all, I wanted to start a thread to have a discussion about these two things that are my only disappointments in this phone.
Let me start by saying I think this phone is awesome, and yes I feel there are a few other faults on the phone (lockscreen delay when running off the battery due to the CPU taking a second to kick in, weak GPS/wifi signal sometimes, heavy banding on gradients etc) But those are software issues and I know in the near future Samsung/Devs will sort this out.
But I had some big complaints that aren't (still I hope not) software issues. Firstly;
- Response Time.
By this I mean when you buy a new monitor and the response time is listed as 4ms or whatever. This is the time the pixel takes to make a full change. A slow response time will cause ghosting. And that's exactly a issue that the Samsung Galaxy SII faces. Ghosting.
I've gone through 4 replacement SII's for various reasons, and on all of them they ghosted. So it's not just my phone. Samsung bizarrely states the response time is 0.001ms which would be there would be no ghosting at all. However there is, quite a bit actually, by my testing the screen is actually around 6-8ms.
I want to see if anyone else notices it. I know there's been a couple of threads on this but I want to see if the majority of people notice this. Here's how to test, go onto white page with black text on, and then scroll down the page at a moderate pace, not to fast not too slow, try it at different speeds as well just in case you don't get it right.
The easiest way I find to do this is use the inbuilt stock news app, load up any story and it'll give you a long white page with black text you can scroll through. As you may notice if you got a decent set of eyes on you, the text will leave a trail. Also known as ghosting. To me, I find this absolutely unacceptable on such high end device.
- Colour
Also, as it's been widely reported and has been noticeable on all my GSII's, the colour temperature is very 'cool', nowhere near the perfect 6500k. As a result, white's look very blue. This is fine and you hardly notice it on it's own, however when I'm using the device at my PC, which I use on a 32" IPS panel TV I professionally calibrated, the whites on the GSII look more blue than the ocean! Technically this is a software problem and can easily be sorted when custom roms come along but jeez, this is some bad stock colour calibration.
Also when you tilt the display, the viewing angles are generally very good, however tilting the display by pretty much any angle adds an extra blue tint to the screen on an already blueish screen.
I'm an absolutely screen quality perfectionist so these points really get to me. Especially considering this is such a high end device.
Overall I'd give the display a 6.5/10.
After the colour temperature has been sorted, I'll give it a 7.5/10.
If the ghosting can get minimized somehow even slightly through software on top of that, I'd give it an 8.5/10.
Secondly;
- Touch Screen
Now we all know about the movement deadzone/threshold on the touch screen which is massively annoying, but hopefully that'll get fixed in the near future. But What I'm going to complain about is the low sensitivity of the touch screen is the best way I can describe it.
On my HTC Desire, I can tap the screen ridiculously lightly and quick, and the device will register the input, absolutely no questions asked. Absolutely brilliant.
However on the GSII the sensitivity seems to be a lot lower, I can tap the screen lightly and quickly and the screen won't register the touch at all. This is pretty damn annoying as sometimes I just tap the screen lightly normally and I have to retap things. Not very often but still. I wish the device was as sensitive as the HTC Desire.
In it's current state I'd give the touch screen an 8/10.
If the movement deadzone and sensitivity got fixed, it'd be a 10/10.
Now I'm sure I had more to write about but I've forgotten now. I'll edit it into the post if I can think of the other things.
Now as I said, I think the GSII is a smashing phone, sure there are a lot of niggles at the minute, but I know they'll get sorted soon. Just the points I've outlined in this thread are things I'm scared won't get sorted. But you never know, I'm really hoping they can get sorted/do get sorted.
As I said I've had 4 Galaxy S2's all had the above issues, and I've used 2 other S2's from friends who also have these issues, so it's widespread, I'm just curious if people actually notice it.
I've added a poll to the thread regarding these issues. Please don't lie to yourself about this stuff, if you notice it, please answer honestly

I honestly hadnt noticed any of this stuff, i even watched a video of the deadzone and couldnt replicate it myself. I also think the touch response is fine you must have a very light finger/thumb!
The ghosting i hadnt noticed probly because i dont read text as im scrolling i tend to go a page at a time and the fact that im too taken back with the smoothness that pages do scroll.
The blue tint you guessed it i hadnt noticed but then again its not often i hold my phone up to specially tuned monitors.. Then again maybe theres a reason for it maybe it helps reduce glare in sunlight, then again maybe im talking aload of ****e!
no offence but you sound like you could moan for england! chill out and focus on the things it does do well and you may notice the negatives less

Personally....I think your nuts. This is the best screen ever on a phone. I have none of those issues, the touch screen perfectly responsive, my whites are white as white can be. You keep getting your phone from the same supplier and that leads me to be what the problem is. mine is perfect in every way. lucky me I guess

Nah it's just I'm very picky when it comes to screens. And I definitely expect the best on such a high end device, unfortunately the SGSII falls abit short on this.
It's still a great device. Really wish I didn't notice this sort of stuff haha.

Best screen on a phone possibly. It's not the best screen ever though, it's good don't get me wrong, but not the best.
And I assure you, your device has everything that I outlined in my original post, it's just down to the user if they notice it or not. When I used my friends Galaxy SII's (who both got it from different places to me and each other) I asked them about this stuff and they had no idea what I was on about, so I thought my phone was faulty and I had a look at their GSII's and theirs have the same problems aswell, they just don't notice them. (They did after I pointed it out though muwhahah)

I must not have a sgs2. Maybe its because mine is from first batch but I have none of your listed issues. After 4 devices, it cant be samsungs fault.

Heh, guys every SGSII have these issues, I'm not arguing that, was merely checking to see how many people notice these issues (not many in the grand scheme of things apparently) there's quite a lot of reports of these problems so it's just down to the user

I guess I have horrible standards. No shadowning on my phone.

The ghosting and blue-ish colortemperature I noticed right from the start. But to be honest: I really dont care. At least the ghosting is nothing which stands out of the crowd... all of them have it ... HTC, LG, Apple. The only reason you don't notice it as much, is the lower contrast on the other displays.
As for the sensitivity: It's a little lower than with my htc hd2, BUT I'm actually glad it is. The sensitivity on the HTC phones is ridiculously high. You don't even have to touch the screen and you end up clicking something, which can be quite annoying sometimes. On the SGS2 I never had any missclicks, nor did I have any non-responsivenesses. Perfect setup for my taste.

I think all of the average joe out there probably doesn't care about all this minor issues. You must have the intention to find the fault of the phone in order to get what you want to find but do you think most of us would be doing this? Haha.. Tbh I don't really care as long as the phone does what I want without falling apart. lol..

Yeah I was a bit surprised by the ghosting, having seen the response time claims, but neither that nor the colour temp (on 'movie') have really bothered me so far.
What has irked me a bit is the image sharpness. On a site like m.engadget.com the coloured text on white background has a dark outline all around it, which to me looks horrible. Anyone else noticed that?

I think the ghosting issue is due to the low fresh rate of the touch screen.It's lower than 60HZ.
When you scroll the screen,the animation is not smooth enough,so you see the ghosting.
It's more of a visual persistence issue.
I remember when some choppy animation showed in CRT,I can see ghosting.
Never the less,when your finger leave the touch screen,let it scrolling itself,you can see the "ghosting" would be less noticible.
But you can still see it,that's because of 60HZ refresh rate of the Display.
I just wondering if there is any way to change the fresh rate of the touch screen.

What are you doing that's causing ghosting issues? There is a definite color temp issue but that's how every amoled screen has been so far. I would take a little bit of blue tint over the black color performance

The thing that causes the ghosting, as I said in my original post, it fast movement. The screens pixels can't change fast enough so things leave a trail.
As I said the best way so see this is to loadup a long page with a white background and black text and then scroll down at a moderate pace, fast but not so fast you eyes your eyes canty follow the line of text. If toy do it right and you've got a decent set of eyes you'll see that the text leaves a trail.

hi,
You are not the only *nut* i noticed that on my device the grey sux big time,... specially on rgb 100 100 100 have a look here: http://forum.xda-developers.com/showthread.php?t=1084543

Yep, there's a lot disappointments with the screen on this phone. However as the poll is so far proving, majority of people don't care for quality as much as us. Only a few others care/notice about the things we're complaining about.

Thanks .. Thats the funniest **** i have read all day...
Theres nothing wrong with my sgs2 and ive owned Hero's Desire's Nexus One's and even an LG2X.. This phone is superb.. This dude does sound a bit anal..

Hey. I can definately notice ghosting on this screen if i purposely try to but as others have said, it doesn't bother me in the slightest. When watching films or playing games it's non-existant.
As for the whites, you yourself stated you can't really notice until you hold the device against your professionally calibrated screen. How are the blacks in comparison? Out of interest, how much was that screen/calibration.
I think the main problem with alot of peoples gripes is focusing on only the weaker aspects of the phone rather than the device as a whole. People want perfection which unfortunately doesn't exist in the world of electrical consumer tech.

now i see this horrible grey everywhere i cannot even look at my phone any more!
I hope that this issue would be enough to change my device!

Hey drm111, as you know I have those problems too.
Did you have them on all your 4phones?
1) As you know I have this topic in wich one screen had this blue ish coat on the screen, noticable from the angles you talk abouth. But the other one does not have it.
So maybe not everyone has that blue coating? Did you investigated that further?
2) As you also know there is this yellowish/darker 1/3 of the left screen, probably some don't notice it. You have to be in a dark room or in a light one really looking for it. You read abouth this huh?
But I you didn't post it here. Aren't you having this problem? And did you have it on al of your 4 phones?
3) Ghosting, yes i notice it to. No sharp text when scrolling,is that the ghosting too?
I have this first generation ipod touch, text stays sharp when scrolling. Should be the case here too.
4) Than you have the grey tints, wich turn pink. You can see it in the topic of nongrata23. But some phone don't have it it seems. Software or hardware?
We need to figure out what is 'normal' and what isn't. As I don't want to send my phone back if it is normal at this point for all the gs2 that are on the market.

Let me start by saying i used to work for a PC magazine and was among those who blew the whistle on the nVidia texture replacement fiasco surrounding the Geforce 5800. I can see a single texture out of place in a high FPS game, so my eye is VERY keen.
The colour of the SGS2 is slightly blue yes, but mine is no worse than the average LCD, including the Retina display.
Response time is seemingly slower than the previous AMOLED screens ive seen, but again is more than a match for the LCDs out there.
I would say samsung have made a trade off between the sub pixel density and other factors. It works for me just fine.
The 16bit thing is interesting. It looks to me like the screen isnt 16bit, but it is using 16bit at times. Thats a driver issue.

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.

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 dream of having a phone like yours.
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.

The anal stage, hmm no let's just leave Freud there. He doesn't have blops on his screen anyway.
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.
Nivekius said:
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.

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 =)

[Q] [???] WTF with the amoled matrix???

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 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.

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.

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
http://imageshack.us/photo/my-images/819/img0005ib.jpg/
http://imageshack.us/photo/my-images/31/img0006pq.jpg/
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.
