SGS screen is awesome, even if colors are not really well calibrated...
Yesterday, I saw a recent Galaxy S and it was really brighter than mine (4 months year old)
I noticed a huge difference!
Did anyone of you got the same experience?

Insulting question perhaps, but did you check the brightness slider of both phones?

Same rom, same kernel, same phone, same country, same settings. I'll try to post some pictures

We just got 4 at work. The supplier told us they only had 1 left a few weeks ago and we had to wait until they got new stock so when they turned up we had one from an old batch and three newer ones. The one older one was very noticably darker then the 3 newer ones even with exactly the same screen settings. It also had a slight blue tint to it.
My brother and I both have I9000 Galaxy. The 1st phone (the older one) was very bright that it resulted in eye strain while using!
After about a month when I bought a new Galaxy S it was very dark compared to the older phone on same settings and same firmware.
So maybe its the issue with some phones or I am guessing that the older phone suffered from backlight bleeding! But now the screen broke and I bought a replacement screen from ebay.

Now THAT explains something. I have a pixel tester and when I set it to black, in a pitch black room I can still see the screen. Well now I know... You sure about that though? Even the Samsung Super AMOLED videos make a point of there being no backlight.
AMOLED does die over time, blue first. So as I understand it most of these AMOLED screens in phones have twice the blue pixels to make up for it over time. I would of suspected that the lifetime is a few years though, not months.
There is no backlight in S-AMOLED displays.

As you can see, there is no lamp, neither a white background needed for the light to reflect.

Thought so. So, can anyone explain to me why I can see my screen in the dark when the phone is showing only a black screen? Such as with the dead pixel checking app I used? Perhaps it does not correctly request true black but even noLED from these forums does it.
I would expect it's due to leakage current.
Each pixel on the screen is controlled by a transistor (actually probably more than one). Even when the transistor is turned off (and the pixel should be dark) there will still be a small amount of current leak through. I suspect that this is what causes the screen to glow slightly even when displaying black.
Of course when the entire screen is turned off, no power is going to the display, so even this small current stops and the screen is darker.
Maybe Samsung has switched to SLCD screens.
The rumour circulated few months ago that Samsung has stopped the production of the Wave and the Galaxy S smartphones because of the Super AMOLED shortage.
Maybe now they are shiping SGS with SLCD.
The SLCD screens are much brigther than SAMOLED.
Here is the comparison:

I highly doubt samsung would discontinue the SGS line for any reason. In fact, they just started to showcase the 7inch SAMOLED most likely for the next gen galaxy tab.
However, here's a comparison.

I'm sure it was an AMOLED Screen, easy to recognize...
I'll try to make some photos.
i got mine when it first came out and i have it on zero brightness setting and it is bright and clear (except in sunlight when it becomes as hard as any other phone to see)
ive tried about 15 of these phones and the screens on all of them were different when set to the highest brightness. The most common differences were darker and lighter shades of blue. a couple were more red than others and looked 'warmer'. The one im using right now is pretty neutral though not sure why that is but they all seem to be different.
(all 15 were running JH2 stock with no lagfixes on i9000m from bell)
Argh...
I have a dead green pixel towards the bottom of the phone... And now that i know its there.. I keep looking at it! Def wasnt dead when i got it
A good way to test the pixels is via the *#0*# menu... red, green and blue.
i always have brightness settings at the lowest and when i was using eclair rom everything was really dark. after flashing froyo rom i noticed straight away even at the lowest settings the phone is still pretty bright but green colour does not look good at all.
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 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.

Why not load up Google site in the browser to do your comparison? That way its identical.

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.
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.
Burn-in, image retention, colors degrading with time my god there are so many issues with SAMOLED screens I personally dont feel that super amazing contrast is worth all that.
It seems with the galaxy S and nexus S the problems werent as huge as they have become with the SGS2, galaxy note and galaxy nexus. With an LCD phone if there is a problem it will be manufacturing problem and not something that would develop after several months.
It seems with every new generation of SAMOLED screen the image quality is getting better but the problems are getting worse. LCD's on the other hand are only getting better with no problems.
I think if samsung is unable to improve on the SAMOLED tech then they should just suspend it for now until they can improve it. Samsung makes the beautiful LCD on my nexus S, samsung also provides HTC with the screen of the HTC one X which is widely regarded as the best smartphone screen. Samsung also makes the screen of the ipad 3. Samsung obviously knows how to make an LCD thats better than the competition if they were to make one for their own flagship.
So what is your opinion on the matter?
people buy galaxy series for amoled screen so i dont think samsung ever going to stop making them..and as per anandtech review of htc one x display make is sony...

Alright, first of all, it's not amoled's problem. it is the pentile technology. it lowers the screen res because it shares sub pixels. However, the galaxy s ii uses AMOLED PLUS, the PLUS means it's like LCD, uses RGB layout, with superb colour contrast along with high res graphics, no pentile ruining the details. so just be patient until AMOLED HD PLUS comes out. It will have: High Res, No pentile, High Contrast. Believe me, it will be 100x better than the One X.

But this doesn't sort out (mainly):
-Unnatural colours which need severe and constant attention as individual OLED lifetimes progress
-Strong possibility of burn in and an effectively similar effect (due to OLED lifetimes as above)
-Generally weak outdoors
I'm not sold on either path for the long term, but there is no denying LCDs in the current day have blown past practically all of their disadvantages. The only benefit i see of OLED technology in the foreseeable future is the ability to produce a "true" black (and lower power consumption as a result). While this is an awesome benefit, there is more far bad than good beyond this.
I'm unsure how far engineering can take OLEDs though. If we're hitting the peak of the bell curve i'd have to agree with the OP. Otherwise, competition and choice is good.
After using a samoled screen I could NEVER go back to the washed out colors of a standard led. I have yet to see any type of burn in on my screen. 90% of it's life will be with screen off anyway so really who cares.

Go to att store and look at the HTC one x screen. Come back and report that it screen is washed out....
This tech of display was a junk which has used on benq-Siemens mobile phone five years ago.
However, Samsung bought this from someone who develop this screen and keeping develop until now. The problems still don't fix:thumbdown::thumbdown:
In my eyes, Samoled looks really gorgeous and can't live without it. But that's just my opinion.

No need to go that far, the i9023's SC-LCD is a stunning looking display. My Nexus S easily stands its ground next to my brothers new GNex (which happily doesn't have strong yellow/green tints stock, which makes me like his more than most OLEDs). Considering that it is close, the only benefit his has is definitely the black contrast (big benefit no doubt). Nothing else is particularly noteworthy above the other.
But i can leave my screen on all day knowing it will be just as pretty as always.
Heck even the nexus S i9023 has such a great LCD in my opinion. The colors are more saturated than an iphone 4 but not so much as SAMOLED which in my opinion is the best balance. It's also so visibly sharper and much better whites. If nexus S had retina pixel density then the SC-LCD could match the one X to be honest.
The advantages of SAMOLED are,
Pure blacks
Fastest response time
A smaller footprint which helps in making phones lighter and thinner
Now to me only the first one is a major advantage. But is it worth all the problems? I really dont think so.

Yes exactly when I first used the gnexus I thought it's going to blow away the display on my nexus S but it really didnt. I preferred the colors on nexus S and it was also visibly brighter at full brightness.
The gnexus does destroy it in black level but then the nexus S LCD does the same to the gnexus when you compare whites, they were simply horrible on the gnexus. I am really surprised google went with a white background in the messaging app, it not only looks bad on the gnexus but would kill battery as well.

Here in the states it is rare to see people with a nexus period. Most that you do see are the sprints. Chances of a 9023 are basically nil.
But yeah if you know someone with a phone that has a good LCD check it out. Or just go down to the store and look. Better yet wait till sprint stores in the us put its version on HTC one x on display. Use that side by side with gnex
That last part was to the person that said LCD sucks. Not harbb
I find it really interesting that most of the people commenting in the thread seem to prefer LCD, but the poll dominates for SAMOLED.
Good point albundy, and i know what you were saying I've never actually seen an i9020A/T/4G myself so i can't compare them to the GNex and i can't remember the last time i saw an SGS around here.
As the poll is worded quite nicely, i think i'll actually vote for once. Too many polls are black and white, nicely played Gambler.
edit: Polls are just that, polls. Just as many people said cpuidle saved more battery than deep idle (i think for quite a while it was more in favor of cpuidle). Look at how that turned out
Back when I would edit photos on my nexus. I really wanted the exact right shade for my eyes on the picture.
Well after I edited the photo on my nexus, upload it to Book it was diffdnt

Guys, I had a Nexus S i9023 (LCD), and my dad has a i9020T (samoled), and all i can say is that I wish I had his phone... the colors look MUCH MUCH MUCH nicer on a Samoled man!!!!!!!
Coming from a G2, the colors on the NS look much nicer. My phone has a minor blue line where the status bar is, but you really can't see it unless you concentrate on that area. The only reason I saw it was because of some friggin' super white background on some webpage
even if they look nicer they are still fake.
fake is not cool.

Heh. Maybe. I enjoy looking at them. Had I been serious about taking photos, I'd probably get an actual camera.
... Not enough to make me regret my purchase of the HTC One.
My previous phone was a S3, which I absolutely loved and had me seriously excited about the S4. However, holding the one I knew which one to go for. Had my one for about 2 weeks now, and I love it but had that niggling worry that I'd regret my decision.
Today, that worry was cleared up.
The Samsung rep visited us today with an s4. and I got to play with it for a short while. Yes, the ability to interact with the screen without touching it is pretty cool, but apart from the lock screen I started getting frustrated with it (kept touching the screen). The health app is very nice, and laid out really well, but like many of the other features, its just not something I need or want.
The actual UI felt laggy, like it was running slower that 24fps. Switching through home pages on both devices at the same time and it just looked smoother on the One. The Samsung rep said he felt otherwise but he is paid to say that
The screen on the S4, in my opinion is much nicer than the one on my One. Granted, the One has quite a dark coloured interface and the S4 has a very colourful vibrant interface, but I just felt the colours were much more alive than on the One.
The build quality is nice on the S4, with all completely uniform gaps around the device, where as the one has gaps etc. However, the S4 does indeed feel cheap to hold. The texture of the plastic doesn't feel amazing, the weight is nice but just lacks that... premium feel.
I know most of these points (if not all) have been covered on reviews etc. but I thought it might be nice to put my 2 pence in as a HTC One owner and previous Samsung user. I do not regret my purchase and still feel I have bought the better device for my own needs and wants.

cool story bro
For balance just to say my One has no gaps, perfect build.

Post on s4 forums .
To be fair I'd love a display with a bezel like the S4 but wouldn't sacrifice the quality of the screen in the One for a S4 display.
The thing is..the screen on the S4 is OLED so the colours will look far more vibrant but, they wont be accurate and its a pentile display. I am quite keen to get my hands on an S4 just to see what its like.
I would say the HTC One is like a Rolls Royce Phantom and the S4 like a Nissan GTR.
Goof choice. I was on deciding which phone to get for a month. Chose the HTC one . Boom sound is awesome. Sense is pretttyyyyy compared to touchwiz. For 649 vs 750 for a s4, it was a no brainer for me. Also im going to sell hundreds of s4 throughout this year anyways lol

Some nice info there mate! I think the only thing i prefer on the S4 is the AMOLED display.
Can i ask a question? Before i do, i know the S4 has improved ALOT on the PPI on the display, however, when i had the S3 i also had my One X, when holding them together, the screen on the One X was such much clearer! Much harder to see the Pixels, but on the S3 the pixels stood out like a sore thumb? Was this something you noticed on the S4 compared to the One? Or have they dramatically improved on this and its now similar to HTC? This is something i would like to know.
My HTC One has no gaps at all.

I was curious about this too, as I had hopes AMOLED had been improved. But honestly I see the same flaws as on earlier iterations:
Dirty whites (turquoise), even in film mode (early measurements reported accurate color temperature, but if you look at it, it is clear that RGB balance is off) - most colorimeters can't measure OLED correctly.
Quite a bit dimmer than the best LCD displays
Discoloration with off axis viewing
Are you sure you prefer the AMOLED screen? I have had an AMOLED for the last 2 years and I can't look at them anymore. AMOLED were OK when LCD's were dimmer, but now the gap is huge.
Honestly, if you can, try browsing the same web pages in parallel on the S4 and the One. It is literally "night and day". It doesn't need to be outdoor. Even in the store the HTC One's screen strikes you as the more vibrant one. I will likely be measuring the S4's screen myself because I don't believe those early measurements that showed a 6500K color temperature. The screen has a green push even in film mode...

I also saw that!!! I was very surprised by this considering my S2 had a smooth experience. I don't know if the overclocking created voltage throttling but it was as you said, laggy and reminded me of the HTC One X when it first started. The browsing experience was horrible.
Are people here actually really paying attention to the S4 screen characteristics?
Firstly, pentile is IRRELEVANT at this PPI.
Second, colour accuracy is good and excellent in the Adobe RGB and Movie modes respectively. Whites are FAR more accurate than the HTC One.
Maximum brightness is less than the One, however sunlight legibility is essentially equivalent due to decreased screen reflectance.
Some fresh reading at Display Mate about it, for those who aren't satisfied with the several 'early' measurements taken by a number of sites.
I know everyone in this forum wants to straight up believe the HTC One has a far superior screen, but it just ain't so folks. Don't get me wrong, the One also has a truly excellent screen, but I just don't see its screen as being a selling point or differentiator in comparison to the S4 screen (neither do I think the S4 screen should be used as a rationale to buy an S4 over an HTC, they're both excellent).
The new oled screen in the S4 is amazingly good. It's actually far superior to the S3 screen.
I played with it on Sunday and I like it.
It's really nice and it will definately sell really well. I love the fact that they added easy mode. This will be such a great way to get noobies to switch to a smartphone($$).
I still prefer the One and I hope it does well. I feel like the One is meant for a different type of user. Samsung is for the mass and the HTC is for those who care.

I have seen the display mate contribution. I like their approach but I don't agree with their conclusions (and it should be noted they have been fierce promoters of OLED displays since the Galaxy S came about).
For one, they fail to mention that even though the measured white color temperature is close to 6500K, the whites actually suffer from greenish cast - so pentile does matter, as there is a discoloration depending on how you look at the screen, and sadly, looking straight at the screen shows a turquoise veil whereas looking more from the side seemed to clean the screen a little from its dirty whites.
Second, the auto-adjust brightness feature taxes the battery so much that no one in their right mind will use it on the go.
When measuring pentile OLED displays it is important to note:
The orientation of the meter has an impact on the measurement, especially on screens with asymmetric structure such as pentile screens...this is something that I would like to quantify on the S4 when I get a chance
Colorimeters will not measure OLED displays correctly out of the box (this point is not relevant here, though, because I think Displaymate used CS-200 spectrophotometer)
So the theory is one thing, but the practice is completely different story. Please believe me that when I saw the measurements made by Displaymate and others I was quite enthusiastic (my S2 does not track as accurately). But while testing both screens in a real life situation, it became very clear to me the AMOLED screen did not live up to its alleged qualities, even in film mode.
Regarding peak brightness, HTC One also has an adaptative brightness mechanism with peak brightness at 530cd/m², but in daily use it is more around 460cd/m². Regardless, the lack of brightness is not totally offset by the better reflectance value, so OLED displays still are poorer performers outdoor and it is even worse indoor under moderate lightning as the S4 does not tap into its peak brightness at any time...
So my question to you. Have you been to a shop to compare both devices and if so, can you in good faith maintain that the HTC One's display does not trounce the S4's AMOLED? The difference was shocking to me. At first I thought it was down to my particular unit but seeing as someone is reporting the same experience, I think this is the screen as it is on any S4 device.

That's true, I wouldn't even bother nitpicking on S4's screen. The only concern could be AMOLED tends to deteriorate faster(which is impossible to tell right now), otherwise I don't see a big con on S4 screen. I feel more comfortable with LCD but hey , a well-calibrated AMOLED isn't bad at all. it's just about preference.
Honestly, if anyone could tell a difference between 440/460 ppi, or even 720p/1080p on a phone, and I'll consider you the "God's eye". I got a phone with 330 ppi (darn it was good at that time) three months ago, and I could not easily tell the difference from my nexus7(~220ppi).

Don't forget the common issue with ugly screen burn in that most people experience with AMOLED from Samsung, pretty big issue as its a matter of when not if and sometimes happening inside of a month, don't even need your screen on for this to happen.
Noidea why this hasn't been mentioned and really should be on the side of the box as a warning.

Pentile doesn't matter so much because of resolution but more because of the greenish discoloration it produces. Dynamic or Film mode has no impact, it is just an inherent flaw. Sure you can get used to it but you come back to an LCD screen you realize what you have been missing out on.
