Mate, I am 50 bloody years old and have spent all day trying to solve this, are there so many 13 year old trolls on here now anyone not agreeing that xxx device is fantastic in everyway is a troll, sad if true :-(

Anyway, let me try that.....

Kev
[Samsung Galaxy Nexus] wilbur-force:
despite thinking at least one of you may be trolling (not you kev).... heres another pic to prove to anyone reading the thread that the comparison pictures arent truly representative.....
[Samsung Galaxy Nexus] human_error:
Camera white balance can make a huge difference to how white something looks in a photo. There is only one supplier of the screens (Samsung), so it can't be that there are 2 different screens out there (unlike iPhones and other handsets where one model has multiple suppliers).
[Samsung Galaxy Nexus] rbs_uk:
This is grey`ish. Must be white balance on camera then why we are seeing such a different colours.
[Samsung Galaxy Nexus] kevwright:
This is the whole point, and I think it is the reason. The S2 allows you to toggle that control off and the Nexus does not.

Kev
[Samsung Galaxy Nexus] oscillik:
that is a feature of whatever modifications Samsung have made to their version of Android, and is not a standard feature of Android phones. No comparison can be made here
[Samsung Galaxy Nexus] dbum:
Oh guys, it's absolutely pointless to judge the screen brightness from photos..

I don't have another phone to photograph, but my laptop screen will do. I didn't change the brightness between these pics. It's just a different exposure metering setting. And look, the same screen is greyish on one and beautifully white on the other photo. :rolleyes:
[Samsung Galaxy Nexus] kevwright:
Now am I crazy or are the whites on the keyboard quite a bit brighter than the main screen in that one.

Trying to upload a couple more photos now...one at both angles....more confused now :-)

[Samsung Galaxy Nexus] htc6500uk:
You need a Galaxy Note then !
[Samsung Galaxy Nexus] kevwright:
I get you, but the ones I am posting are good examples of what I am seeing here, and its the best we can do I think.

Problem here seems to be there is so much suspicion and mistrust, its hardly worth continuing (with notable exceptions)

That`s nearly a tablet :D Too big for my pocket.
[Samsung Galaxy Nexus] jms.flynn:
Well i know that taking pictures is pointless but here is a picture I took all max brightness. S2, Galaxy Nexus and iphone4.

http://flynners.me/images/photo.JPG
[Samsung Galaxy Nexus] kevwright:
Its not totally pointless as long as the picture fairly matches what you see. I think the S2 is quite a bit "whiter" there? I think mine could be faulty, will take into an O2 shop and try another one.

Kev
[Samsung Galaxy Nexus] originlabs:
I think you're right. I just went into gmail and carriage returned to get a blank screen. If you then hide the keyboard, the display dims slightly. If you bring the keyboard back, the white area which is left becomes brighter. I had to cover the keyboard area with my hand to clearly perceive the difference though.
[Samsung Galaxy Nexus] kevwright:
Surprisingly usable actually, and not too bad in pocket either, and the screen is awesome, none of this grey whites, although I actually think once a dev or two get to grips with it they may give us more control over the screen power.

Thank you!

The way I proved it (to myself lol) was on the S2, if I keep the "Auto adjust screen power" toggle on, the screen is much dimmer at max brightness, almost identical to the Nexus.

I suspect with the bigger screen, Sammy have decided to mute it a bit to save battery and not get slagged off like Apple are ATM.

Its only contrast freaks like me (it helps with my eyesight issues to have bright whites) that care :-)

Kev
[Samsung Galaxy Nexus] dbum:
A picture with different handcents on it isn't pointless actually. It allows a comparison again.

Just one more example why taking a photo of a single phone makes so little sense: Now I did change the screen brightness between the photos. First pic is at 0%, second at 100%! And you will agree they are equally bright on the photos, wouldn't you?

Proves that taking photos of a screen to evaluate its brightness is pointless because the camera's exposure meter will always regulate the photo's brighness to the same level.

Last one.

Gmail. max brightness. on white paper. with a white envelope next to it. Kev - if your screen REALLY isnt bright and white id take it back !
[Samsung Galaxy Nexus] kevwright:
Yep, I think for now, I will back it and stick to the Note and S2, I reckon the S2 will get a workable ICS fairly soon :-)

Cheers

Oh, meant to say, one last test if you don't mind. Go to People App. New contact. make keyboard appear and disappear. Does yours dim noticeable when keyboard removed and brighten when its onscreen?

Kev
[Samsung Galaxy Nexus] wilbur-force:
interesting ...... it does dim very slightly .... unless thats just my eyes reacting to the dark to white ....

strange.
[Samsung Galaxy Nexus] kevwright:
Thanks, kinda confirms it is the Auto adjust screen power depending what is on it setting, because on S2, I can make it do *exactly* the same if I put this feature on, making it the same as Nexus.

All we need now is someone to give us the same toggle as Samsung do on S2 (and Note)

Thanks for your help tonight mate, still not 100% sure if mine is faulty or we just see stiff different :-)

[Samsung Galaxy Nexus] titooo7:
I own a SGS and I bought a SGS2 because I wanted a more powerful phone with better camera.

The SGS2 was great but I really could stand the screen because the colour was oversaturated.

The black was real black, that's true, but dark brown or dark green were also almost black and the whites were not really white, so I had to return it.

BTW if there were an app as good as Voodoo Control for SGS1, which let you control the colour totally, I wouldn't reject to buy it again.

Now I was thinking to buy a Galaxy Nexus but after reading some comments I have my doubts again.

I guess that's how the late Amoled screens are, they look great but they don't represent the reality at all. :(
[Samsung Galaxy Nexus] htc6500uk:
Probably a good decision - I'm sure the Note will get ICS too as it runs faster than the Nexus. The only problems I forsee are that, from what I have read so far about the Nexus and ICS, that the excellent native media playing facilities of the Note (Xvid/MKV/x264) will need to be added plus support for the FM Radio. I'm happy to wait.

It's a pity that the Note has not been officially announced for North America and is not really mentioned/compared/benchmarked.

For those who worry about the size, I find it perfect - it's smaller than my wallet and it fits in any of my pockets.
[Samsung Galaxy Nexus] jabok:
Don't be such a plum, who the hell hasn't seen an iphone 4/4s screen, it's been around for ages and tonnes of people have them.

It's a quality display, to be sure, BUT it's so ****ing tiny as to be unusable for any length of time to me. If you can live with squinting at that pokey wee thing for more than 5 minutes, hats off to you. :D
[Samsung Galaxy Nexus] Jebus99:
Seen both. GNexus blows everything out of the water. Anyone saying otherwise hasn't seen the GNexus screen.
[Samsung Galaxy Nexus] Taggard:
Just put my GN screen next to my wife's iPhone 4. Hard to compare, because the iPhone 4 screen feels so small. The GN is at least as bright and white when you take it off auto brightness and adjust it to about middle.
[Samsung Galaxy Nexus] ericshmerick:
I have an iP4 for work. Wife has an iP4S.

My GNEX screen is so much better.

Just another opinion...
[Samsung Galaxy Nexus] kristovaher:
The best screen I have seen yet.
[Samsung Galaxy Nexus] farfromovin:
I've had the ip4, and just left my qhd sensation for the GN. This screen is great. It appears to me to have the pixel density of the ip4 but its much larger of course. Best display I've used on a mobile thus far.
[Samsung Galaxy Nexus] supercurio:
Hi guys.

I just subscribed to the thread.

As I know a few things about Super AMOLED screen and the challenges involved in their color calibration; if you have questions: shoot!
[Samsung Galaxy Nexus] voxigenboy:
What's with all these Photoshop'd pics? ;)

Interesting about the auto-bright too dim... That's usually an issue with AOSP roms.
[Samsung Galaxy Nexus] ericshmerick:
What's with the artifacts on a white screen? Seems worse than the SGSII screen.

Not complaining, just wondering why it isn't really white. I know it's an issue with SAMOLED and the blacks are wonderful, just the whites are not white at all.

No dealbreaker, just annoying.

On a side note, while I have your attention, does installing Voodoo sound on the GNEX do any good? I don't recall if it has a Wolfson DAP and would hate to install Voodoo Control Plus only for it to not do anything.
[Samsung Galaxy Nexus] supercurio:
First of all, there is no such thing as "white" ;)

White is something your eye identify as "white" after a few minutes, depending on the lighting conditions.

If a screen has more blue than the ambient light and is dimmer, it will appear blueish.

If a screen has more red than ambient light but is also brighter than the ambient light, the screen might very well look "white" to you, and the ambient light colored.

Standard contents (images, movies) are created for a color temperature at 6500K but a lot of screens sold in commerce actually have more of the blue component, that's why we are used to that.

From the photos I see here, it seems Galaxy Nexus targets 6500k which means moez red and green than Galaxy S II and iPhones.

Thing is there's a lot of variance between samples, and so far nobody managed to calibrate SAMOLED screens to get a consistent color reproduction on every device.

That's why you'll see on this thread people saying one thing and the exact opposite, which leads to endless joy in forums :D

Calibrating SAMOLED is something I work on those days, and it's challenging.

Voodoo Sound is not available for Galaxy Nexus. I don't know yet if I will work on this device's sound. It will depends on the potential and popularity of the device.

BTW is a manual sound quality optimization process based measurements & listening tests, usually implemented as a kernel driver and very much specific to a hardware+software platform.

Its limited to very few devices because few are capable enough and it's a very time-consuming process.
[Samsung Galaxy Nexus] ericshmerick:
Thanks for the responses. If I had a crystal ball, I'd say the GNEX will be quiiite popular...

;-)

It's the only Android phone I've ever owned that has literally ended my thirst for something better. They are going to sell a ****load of these things, IMO.
[Samsung Galaxy Nexus] BluechipJ:
While not specifically the the iPhone, the IPS display is made by LG who also makes Apple's Retina Display:

[YOUTUBE]vb_muwDjmRs&hd=1[/YOUTUBE]
[Samsung Galaxy Nexus] supercurio:
If you have a Galaxy Nexus and a colorimeter, I suggest running a few measurements using the Voodoo Screen Test Patterns app I just released in this purpose.

You'll need this app and a colorimeter. On your computer, HCFR does a good job at measurements & graphs.

Colors perception is subjective but.. its also a science ;)
[Samsung Galaxy Nexus] emorej:
GN screen should not be compared with iPhone 4/4s screen, its 3.5nch vs 4.65inch,sure iphone will have advantage but not muc:Dh, imagine if you put GN screen on a 3.5 inch size iphone fanboys will cry...

[Samsung Galaxy Nexus] luapclark:
Do you think its worth me trying to get some results from a UV/vis spectrometer? I have access to a Jasco v650 I'm sure I could fit my gn inside and scan visible. Does your app keep the screen on?

If so what data would be useful? Set to white and scan at 0% 50% and 100% brightness?

I am going to the clean room today so could post back with some data if you're interested?
[Samsung Galaxy Nexus] Fpad77:
What the hell Kev. Are you for real....

You do realise that the Gmail app looks grey because it IS GREY. It is not a white background at all. You need your eyes tested, not your display..
[Samsung Galaxy Nexus] devadvance:
If I remember correctly spectros are better for color reading but not for luminance or actual human perception matching aka calibration. If you want to try, I'd say go for it, since I won't be getting my GN until next week. Then I can use my colorimeter on it.
[Samsung Galaxy Nexus] luapclark:
Yes it will have no calibration for absolute luminance it would give data as a % compared to the source, which I can also get a scan of to normalise. It will give a good indication of the white temperature though I would have thought? I will try anyway and see what I can get.
[Samsung Galaxy Nexus] ericshmerick:
I love the nit-picking.

The display is incredible. It's a phone, not an IPS monitor for critical wedding photography work.

Yikes, we get a bit tangled up in the minutia, no?
[Samsung Galaxy Nexus] justabrake:
is it me ! I thought the iphone white was the realist picture of them all Sorry :o
[Samsung Galaxy Nexus] Davidsmonkeyroost:
I've been using my GN for 4 days now and I'm happy with the screen.

I've never owned an iPhone. And that I haven't doesn't make a difference to if the GN screen is good or not. Its subjective.

The screen is crisp - I am holding it up 70mm from the end of my nose and cannot see any pixels on small text or diagonal lines. I can't focus any closer than that. In use, I hold it at least 200mm from my nose so resolution is beyond my perceptible limits.

I run it at auto brightness and that's fine for me. In low light I would say its lowest setting is too high. I would like it to go low enough that I can use it in the dark without it destroying my night vision or making me stand out in the street as being on my phone. I think like most phones I have owned or used they set the min too high so it doesn't matter too much if you have your finger covering the light sensor in daylight.

As for colour, well colours are very vibrant. It does occasionally make me go Wow when doing mundane things, which is a plus. Looking at colourful and bold photos look incredible.

As for White; this is extremely subjective. What is white? Show me something that is white! I think most people who have tried to paint a wall the same shade of cream will know the feeling of when they get the Calico on the wall only to see it stand out against unpainted areas because it was magnolia before. You have standards such as Pantone which say that white should look like what they say white should be and that's fine, its a standard. They do have different whites depending on colour temperature to keep in mind. Getting back to the GN; if I browse the web and pick a random photo, I can see what part of it is 'white' and what part is black, as far as I can perceive.

Blacks though, are black in a dark room. No back light here spoiling the show.

Its the end of Autumn here in the UK, so its not incredibly bright (but quite glary). But I can comfortably read the screen outside on Auto in daylight. When its really bright here in the summer, its usually warm and so I'm not usually using the phone much if its nice out. I'm on my bike as much as I can or in a pub garden. Got to make the most of what little sunshine we get here!
[Samsung Galaxy Nexus] Davidsmonkeyroost:
Forgot a couple of points:

Refresh rate / response time is good - no blurring when watching fast paced videos.

Banding - some people say it doesn't exist at high brightness, but I don't need or want to use full brightness. At Auto looking at a solid light grey full screen image I think I can sort of see what people define as banding. Its like looking at a grey sheet of paper with a slight grain to it, or maybe how a lazer printer would print grey. But then other people say banding is where you have a dark shade of colour going to a light shade and seeing solid bands of colour making it up. The GN does not exhibit this type of banding. It does gradients very well, in fact there's quite a lot of Gradients in ICS.

I don`t understand what`s going on: I have just been in Three shop on Oxford street and had a play with it and screen is so bright, just great.

But I went to o2 shop last week and it was terrible, soooo dark. Also spent around half an hour with collegues phone, also very dark screen. All phones were on max brightness and AUTO off.

Cannot explain this. Could they be using different screens ?! I doubt, very strange.

After seeing Three demo unit 2hrs ago, I definitely can say screen is amazing :cool:

I have a 4S and the screen is nothing to write home about. I find the amount of praise it gets is really unwarranted. It's undeniable that the 4S screen is good, offering a superb resolution, but colours can be pastel like.

Apart from the resolution, I was more impressed with the Nexus S screen over the 4S. I don't at all sit here looking at the 4S screen and go "oh I love this screen!" When I first turned on my Nexus S it gave me that "wow" factor.
[Samsung Galaxy Nexus] gambiting:
You actually make me lough. I have both the iP 4 and the Galaxy Nexus(I'm a registered iOS and Android developer), and the Super AMOLED screen on the Nexus is like 100x better. Better blacks, more lively colours, and it's DEFINITELY brighter. I think your Nexus might be damaged, go and get a good one.
[Samsung Galaxy Nexus] case0:

[Samsung Galaxy Nexus] mysterioustko:
The GNex definitely has the best screen in this picture followed by the sgs2. The phone in the bottom right looks washed out (perhaps it's the angle), and the phone in the upper left just looks dull (maybe it's because of the vibrant colors right next to it). I showed this picture to my girlfriend (who doesn't care about phones at all) and she came to the same conclusion.
[Samsung Galaxy Nexus] Japears:
Found this thread on google when searching the same problem that kev has, I picked up a gn today, and for one it isn't as bright as my iPhone 4, but is perfectly fine, though I have noticed the same dimming on whites of the page you are viewing is mainly white. Even with auto brightness off there seems to be some power saving act in operation. Example whites on Facebook are noticably brighter when the keyboard is up.

[Samsung Galaxy Nexus] wasya152:
anyone who doesn't think this is the best screen up to date, is on crack. the iphone? you need a magnifying glass to use that tiny thing. what's the point when you always have to zoom in to see stuff. by far this is the best screen out there right now. the auto brightness just doesn't do it justice.
[Samsung Galaxy Nexus] justabrake:
everyone still has to compare to the iphone, Must be something to it :)
[Samsung Galaxy Nexus] wasya152:
the iphone has a nice screen. it was the best when it came out. however, i think it's much easier to make a nicer 3.5 inch screen than say 4.3 or 4.5. however, my cousin has had the iphone for a while now and when he played with my nexus, he was amazed. that must say something....

[Samsung Galaxy Nexus] rosswaa:
something I noticed I think screen problems maybe something driver related

If I turn my brightness up to full it doesn't seem to go that bright, whites aren't amazingly white and I feel it could go brighter

I noticed that when the phone turns off and on again, where it says Google with a unlock sign on it the screens brightness is immense and crisp

Google is whiter than white and really really bright, as soon as its fully booted it looses its crisp bright whiteness that once was lol
[Samsung Galaxy Nexus] sauron0101:
It's a good screen - most people I've asked around who have played around can't tell that it's a pentile. I have to squint and look really close to tell.

I think that the color temperature is a bit off and that the screen could use some calibration. Otherwise, outstanding:

- Good contrast (if you take an LCD and go into a black room, then display a black background on an LCD, it will illuminate the room)

- Viewing angles are good

- Response time is fast; no visible input lag or ghosting

- Outdoor usage at 100% brightness is among the best

- High resolution, despite pentile makes text pretty good as well

My biggest complaint after playing around with a Galaxy Nexus is that at 100%, with a white screen (ex: most webpages), the battery drains very rapidly.

Check the article again. Looks like they made a little uh-oh: the LTE Nexus on the left isn't properly rotated to the side orientation. If you look carefully, you can see that some of the thickness is entirely due to the perspective - you are look at part of its back. They have updated it with the correct view:
