Most correct picture ROM - Galaxy Tab 10.1 General

One thing that have been disturbed since I bought our TAB 10.1 is the oversaturated colours, even if the movie picture mode is used, there are two many errors. I want natural colours, the picture should be near D6500 as possible.
I know that for about a year ago there where a guy on XDA that was devolping an app for making the picure more natural.
So the question is, which rom(that is stable) got the most natural and correct picture?

Not all Nexus S SAMOLED Displays are the same

Hi everyone,
I'm starting this thread to show you guys that not all Nexus S AMOLEDS are the same. I purchased a Nexus S on launch day from one store, and my brother bought a nexus S from another best buy store. We were comparing each others phones, and mine turned out to be darker than his, specifically the whites. We compared our screens at full brightness, and we set the same backgrounds, and his was noticeably better looking. So I went and exchanged mine, the new one I got still suffered from having darker whites, but it was not as bad as the first one, so when we compared them again, his was still better. I took a few pictures of the new one i got compared with his (on right). It may not look like much, but if you look at it in person, it's very noticeable when they are next to each other. I think you guys should compare your nexus s with a display model at a store, or with someone else to see what I'm talking about. I think it's easiest to see what i'm talking about if you look at the search widget. Like I said the first one I had was worse, but I'm comparing the newly exchanged one (left) with my brothers (right).

I agree with you
It's like my mom says not everything can be 100% perfect
Yeah I know what you're speaking of. I started a thread here about it: http://forum.xda-developers.com/showthread.php?t=877497
I went through this when I bought dual monitors for my computer. It is nearly impossible to find two monitors exactly the same. You will not know the difference unless you keep comparing it to others.

lol thats true. it made me laugh lol
download a solid white wallpaper. set the brightness to the highest. if one of them is cool blue white then this is good screen. if its warm yellowish white, then its a bad screen.
also there is the issue with pinkish disaplay. download a solid gray wallpaper. set the brightness to the lowest, if the gray turns to pink a little. you have a defective screen no matter what others tell you. if it stays gray " like my old Samsung Galaxy S " then you have a perfect screen.
AND there is also the grid pattern matrix you can see on the lowest brightness on the same gray wallpaper. ALL of them are more visible on the Super Amoled screens, just try to get one that is not very noticable.
if you got all those 3 perfectly " with no dead pixels or stuck pixels. then your phone worth alot.
i sold my galaxy S USED more than i bought it NEW because of these effects when i mentioned them to the buyer and he saw with his own eyes the difference. plus it didnt have single scratch on the whole phone so it was like a brand new.

No one's nitpicking. It's a matter of what you're willing to settle for. I paid my 580.00 for a phone to display the colors correctly. I didn't pay that much for the display to change colors just because I lower the brightness.

ya, after i took pics, i realized they were not on the same page on the home screen.
This is a very common issue on the Galaxy S phones too. Different suppliers are used in the manufacturing process resulting in some screens with warmer color temps, and others with cooler ones. The Engadget review of the Nexus S specifically called out a warmer temp by the way.

Dumb question, but did you verify that the brightness levels in settings are set to the same values? Or at least compared the two phones when at the lowest and highest settings?

ya, i actually made sure they were both brightest, and when they are both on the lowest, you can tell one of them displays brighter whites. But the first one I had was worse than the one I have in the pictures on the left, it's hard to notice that you have a screen that does not produce nice whites, unless you see another nexus s that does a better job.
I actually like the ones on the left, the ones on the right crush the blacks, resulting in basically everything washed out, even if it "looks" better to you, it isn't from a calibrator prospective.
The Evo 4G had the same thing going on with its display. HTC used 2 different Manufacturers for the screen, One Novatec, One Was Epson. I believe the Novatec panel had darker colors (warmer?) resulting in more of a purplish color on blacks (what ll_l_x_l_ll calls pink for whatever reason) While the epson didnt have any purplish tone, but most say had a washed out look.
I would say though that on the nexus S, probably 99% of them are going to have a little purplish effect on the lowest brightness setting. If the OPs brothers phone has no purplish color, that would be the first i have seen. Ive seen many many demo units, several video reviews, and even the 2.3 rom ported to other galaxy S phones, and they all have the "purplish" display.
All my whites on my phone are really white, and blacks are really black.
Only be concerned if your screen looks like this

That would definatley warrant an exchange, because they are NOT supposed to look like that.
My Screen looks better than his I9000 though too, but that could be his camera too washing out the colors a bit

Yeah my camera isn't great, it was poor light but it was enough to show the difference.
My i9000 screen is pretty incredible, I'd be impressed if I saw one better.
Oddly though, you say that if it turns blue when the brightness is turned right up, it's a good screen - my Nexus S does that. But it's yellow when the brightness is low.
Personally I think I'm going to take your advice in another thread. I'm going to return this phone for a refund, enjoy using my i9000 for a while as it's now apparent that the screen is excellent (I never really had GPS issues either, so I'm pretty lucky), and go around stores when they have stock to find a screen that compares favourably against my i9000. I'm in a nice position that I can do a side-by-side comparison each time.

bazinga.
hit under the belt.
Why not load up Google site in the browser to do your comparison? That way its identical.
lol
So, I guess not many of you have ever messed around with the LCD monitor in front of you (if you have one).
Mine I can set to be a cool white or a warm white.
Here is the real problem... Your brother is smarter than you. You see, there is a difference maybe in the screens. But instead of him *****ing about it, he likely just said his was better. Thus leaving you with the **** screen.
The tables could have been turned if you would have said "HAHA your screen is broken, and mine is better" the second you found the screens were different. Then it would be him here all upset about the screen.
The things people ***** about on this form are just crazy. And no, I don't care about how much you spent on your phone. When you buy any product you should only have a expectation that it is usable, not perfect. And thats mostly because perfect is mostly opinion when it comes to things like this.
Also, this is a phone, not a pro display marked for having the most accurate color production.
What kills me most is the people who take phones back over and over for problems that only exist in their heads. All you are doing is raising the cost of phones and keeping them high for everybody else.

Milestone 2 TFTerrible Screen

Is anybody else noticing how dull the colours on the Milestone 2 is? ive looked around and havnt been able to find anybody else talking about it.
I took a few shots of it beside a ZTE Blade and a Zune HD (Zune on medium brightness, both phones on 30% brightness) and strangely enough the Blade's TFT screen looks identical to the Zunes OLED... and the Milestone looks awful!
im confused because the Blade cost 100 and the Milestone cost me 450!???
photos and a video here:
http://picasaweb.google.com/savagecabage/Milestone2TFTErrible#
is there some settings that im missing? im hoping there is. i feel like ive been screwed my motorola lol but i suppose its my own fault, i didnt really do that much research on the screen, i just presumed that a phone that cost 4 times as much as my last phone would have a decent screen
i got this info from pdadb.net, does this make sense to anybody?
ZTE Blade color transflective TFT , 262144 scales
Milestone 2 color transflective TFT , 16777216 scales
also there only seems to be about a 5-10 degree viewing angle on it, once the phone is tilted out side that the colour drops again, oh well
Do you have any screen protector or something on the MS? Are you sure screen brightnes is @30%? I have Droid2 Global and a Milestone (1) which both essentially have the same screen as on MS2 and it is not looking half that dull! True, colors aren't AMOLED like, but I would call it above average for TFT screen
Edit: just looked at the rest of the pics you provided and honestly the ZTE screen looks worse than the MS2 when it comes to color representation - everything feels redish/pinkinsh on it. The AMOLED is not comparable under this conditions. Take some photos at daylight to see "the other side of the coin"

no screen protector on and im using widgetsoid power widget and have both of them set to 30% using that. yea maybe its that the ZTE Blade colours are over saturated and im just used to look at them that way, but there is definitely some colours wrong and dull in places, like the red in the youtube icon is more of a washed out red than thier logo usually is
ah not to worry i suppose, i probably wont even notice it in a few weeks, ill be selling of the blade then so i wont have anything to compare it to anymore
awesome phone apart from that though
if i find some better examples ill post them,
thanks
I also noticed this the night I took my Milestone 2 home... I was a little concerned at first, but the soft colors eventually grew on me and I dont mind it so much now

Its not just me so! thats nice to know im not going mad. im sure ill get used to it soon as well, its not the biggest deal breaker anyway, im just into a bit of photography in my spare time so i like being able to look at photos on my phone in the correct colour
this guy says the screen is vibrant? i must go ask him how he gets it so vibrant, maybe theres a setting somewhere to turn the colour back on
http://www.pocket-lint.com/review/5213/motorola-milestone-2-android-review
"It is vibrant and displays colours well"
According to DisplayMate (which is an authority on displays) the Milestone Droid has the most accurate colors of ANY mobile screen. SAMOLED has awfully inaccrate and fake colors due to the poor pentile matrix arrangement. I dont know if the OLED screen on the Zune is full RGB or also pentile, but its colors are also "gaudy" and no realistic. Compared to my LG's IPS panel, the Milestone is pretty close. I suggest that your eyes are just accustomed to fake and bleeding colors, or your LCD might be a lemon.
The Milestone's display is IPS with full color gamut and true 24 bit color, not a cheap TN panel like almost every other phone. However, Android 2.1 and 2.2 have galleries that are only 16 bit, so pictures look compressed, not the screen's fault. Blame Google.

This picture indicates just how bad the ZTE screen is. That background on the right isn't even remotely close to being white like it is supposed to be.
It appears to me that your Droid brightness settings are too low (or is on auto dimming) because the Droid's screen should be much brighter--something like 550 nits for the Droid to 300-350 nits.
Also, your eyes are clearly accustomed to "gaudy" and inaccurate colors from OLED, whereas the Droid's display is very accurate.
Have a look at this DisplayMate article that breaks down why the Droid is accurate, Galaxy S' SAMOLED (similar to the Zune's OLED) inaccurate: http://lh3.ggpht.com/_BZtTwn-keT4/TSb4DpoadvI/AAAAAAAAAc0/0pqLgfd_Uik/s640/IMG_2833.JPG
I recommend manually setting the brightness on your Droid. Personally, I prefer the screen very bright. Let your eyes adjust to the Droid, and if you still want overly saturated/fake/inaccurate OLED colors, then please sell your Droid 2 to me
ive had my milestone 2 a month and when i look at it i still think how awesome the screen is, really sharp and clear, colours are vibrant, and ive had to turn the brightness down to almost the lowest it will go because its so bright! lol.
but as with most things peoples perception varies, what looks or sounds great to one person might look or sound horrible to another..

dont mind thoses pictures actually, using that camera wasnt the best idea, it white when looking at it, no red/pink in it
i think your talking about a different phone anyway, i had a quick look around display mate and couldnt find anything about the droid 2. they have stuff on the droid 1 but nothing on the droid 2. prolly a similar screen but might not be the same

yea at first i was thinking that my eyes were just accustomed to "gaudy" colours as you said but if thats true then it means that every screen ive looked at in the last few years has been incorrect.
i just put my xperia x1 and touch pro on ebay and realised that they look "normal", i put some photos on them to look at and both of those seem to be roughly the same as the zte blade, not as saturated as the ZTE blade colours ill give you that, but similar enough, and i have two monitors on my computer here and the photos have exactly the same "normal" colours, but then looking at the same photos on the Milestone 2 they look fairly washed out, even with the brightness at 100% there is a big difference.
i change the brightness settings all the time though but in the photo they were both at the same brightness so it shouldnt matter what % it was just to comapre them
anyway im definitely not imagining it, ive been doing photography and graphic design for a good few years now so my eyes are able to tell small differences between colour at this stage (i wouldnt be much of a photographer/designer if i couldnt) and its more than a small difference, enough that id bother posting a thread here to see if anybody else is noticing it!
well, ive come to the conclusion the screen on my milestone 2 it a lemon... or maybe motorola is the lemon. one of those two, or both lol
i wont be selling it anytime soon though unfortunately sorry im enjoying this phone way to much, the issue doesnt really bother me enough to do something crazy like that..
i just thought it was strange to see it on a 450 phone thats all
mine sometimes as problems, but not that bad :/
dude i really dont think your phone or the screen is the problem, i think its your eyes, just look at the picture of that Rovio screen! the left one is white, the right one is PINK! obviously the m2 has a much more accurate screen.

i totally agree about the sharpness and the clearness and the vibrantness of the screen, great detail in it. and i just realised all the colours are really vibrant apart from light blue and red, everthing else seem to be normal. the light blue looks the palest, and then the reds arent as bad but definitely still some difference compared to my computer monitors and other phone screens ive been comparing to.
ah not to worry anyway, i was just curious whether it was a problem everybody was having or if it was just my screen, i wont lose any sleep over it

yea i didnt really notice that when i was uploading the photo, i just explained that in a post a few seconds ago. it must be just the camera im using, both of them are the same whiteness when looking at them, i was just trying to show the difference in the red colour. the zte blade was at an angle too so i dont know where the pink came from, i just looked at angry birds again on that phone,and at an angle and its still white, stupid camera lol
Savage, I think you might have a bad screen. Can you compare it to another Global or exchange it? The Droid 1, 2, R2D2, and Global all have the same IPS panel as reviewed by DisplayMate, which thinks it is the most color accurate on phones. The Droid does use dynamic contrast, so its colors are sometimes deeper than at other times. I notice this especially when changing wallpaper. Some look absolutely stunning (almost as good as my IPS hdtv), but others are washed out. This is part of the dynamic contrast kicking in and Android's limited 16 bit gallery. I despise dynamic contrast and always turn in off on all my monitors. Unfortunately, I dont know how to disable it on the Droid

Yeah, I have the d2g, which I believe has the same screen as the m2, and I absolutely love the screen. The colors are very accurate and sharp, I used to have the captivate and I never liked how innacurate the colors were, whites never looked white, they looked grayish, and every other color had a bluish tint to them

Same here, my brightness is always almost all the way down except in sunlight where I turn on auto brightness.
Great Display.
I have a lot of phones with different displays including an Xperia with the Bravia engine which I returned for my MS2 and I would have to say that this is one of the nicest displays out there.

How good the HD2 is - comparison

I flashed WP7 on my HD2 and set it to match my Focus them and layout. I always knew my HD2's display was good but now I have proof of how good. To me it matches the color richness of SAMOLED but doesn't have the ugly pentile look. It certainly looks better than the HD7 I had.
The focus seems a bit clearer, but something I've noticed with every amoled and super amoled panel is there is always a blue tint to it.

Yeah...in the picture it does look slightly clearer. I don't know why because I took two shots and that one was the better of the two and in person the HD2 screen is just perfectly clear. But the color production is what stuns me. To me it looks identical...except for maybe the black depth.
I have noticed the blue'ish tint you are talking about on my Focus and have commented that my iPhone 4's display is better than SAMOLED for color accuracy, viewing angle and quality. At the extreme viewing angle is where I see the blue'ish tint mostly and it is absent on the iPhone 4 display. Yet the iPhone 4 display has just as sharp a viewing angle. So it puts it above SAMOLED.
I had an HD7 when they first came out on T-Mobile and thought it was the stuff. Since flashing WP7 on my HD2, I am so amazed at the picture quality my HD2 puts out that I would much rather have the HD2 display in my HD7. I just got done with a little Angry Birds play ...the first time on my HD2 with WP7...and the colors and vividness of it just floors me. I've played Angry Birds on it a lot with Android. But WP7 Mango must be handling the display better because it just purely looks gorgeous.
I decided to take a look at the light theme and low and behold, it looks better on the HD2.

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:
http://imageshack.us/g/685/bild4ht.jpg/ (There is only one color displayed and there are lots of dark lines and smudges, ignore the grain)
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.

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!

Yeah I've never seen such problems on a screen before, hopefully just a bad batch, but on two different models?

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.

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.

Here you go:
These are pictures made at the same time and light with a DSLR camera and "normal" phone camera.

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.

Are you joking???
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.
