how many have devices like this? It doesnt seem to disappear on mine until about half brightness up.. and even there i can slightly tell. is this a problem on most phones or only some? Also with light usage i'm losing over 10% per hour, doesnt seem right at all
All AMOLED screens have that issue at low brightness, it just varies from phone to phone. Give it a few charge cycles before you start looking at the battery. The battery on my Nexus drained extremely quickly when I first got it but it's been lasting longer and longer with each passing day (3 so far)
My screen is the same, you need to be at half brightness to get a decent image. Auto brightness in full darkness makes you think that the screen is totally broken.
yours has like bands of a different shade too? mine has one thick one on the right of the screen and it's pretty annoying.. about to go into the city tomorrow to exchange it but if there all like that then i dont know
I went in to the store, and they said that they wouldn't switch it out.
Mine looks fine at lowest brightness. I use mine mostly at.about 10% brightness and look great.

Yes ! I thought that mine was also broken. It is good to know i am not alone .
can we get a screenshot?
Would it even show in a screenshot? Yes, it's AMOLED... that's the way it is. More than worth it.
It wouldn't show in a screenshot since this is a hardware related issue. And I don't think it's normal if it has brighter spots like explained. Mine isn't as smooth as you would expect either at lower brightness levels but it is not like explained by the OP.

All SAMOLEDs sacrifice clarity and color representation for slightly better black levels. Just the nature of the screen technology. All 4 Samsung models (and all 7 phones) I've come across have it.

I've never seen the banding effect before, and this is coming from someone in a household with two out-of-commission Galaxy S', two GSIIs, a Focus, and my Nexus. The PenTile screen door effect can get to me if I'm looking for it, but that's the only SAMOLED issue I'm familiar with.

I actually like the slightly grainy look mine has at lower brightness levels
Would Voodoo Control be compatible with this? It was an awesome feature that my Nexus S had!
Sent from my Galaxy Nexus using xda premium
Not only is mine grainy at low brightness, it also has a pink and green tinge (in opposite sides of the screen)
It doesn't seem to happen on the 1st gen AMOLED (Nexus one, not grainy at low light) or S-AMOLED (Galaxy S, it did have an overall blue tint, but it was on the WHOLE screen)
Not completely noticeable, but would have expected better. At 40% or higher, its barely noticeable.
Got the same problem 40-50% and its barely noticable, any lower and i can see much distortion.
I know its a hardware thing but is this something that might be fixed with a future update or are we stuck with this?
The screen will look grainy on white/grey backgrounds at lower brightness settings, but there should not be any vertical/horizontal banding on the screen.
My first phone had a vertical bar of banding going down the entire screen, and bothered the crap out of me. Went in this morning and had it swapped with a Nexus that has no issues. For the price that we're paying for this phone (especially those with International unlocked imports) it better be perfect.
yup, i only ever see it in one place (the grain), and thats on the store before anything loads (an all gray background). Don't see it on white or anything else... that i know is pentile.
Galaxy Note is similar at lower brightness levels, must be AMOLED.
iPhone 4S is best if reading at lowest brightness levels is very important,
but in brighter light the Nexus and Note look amazing.
GSMArena did a display test on the galaxy S3 and it is much brighter at full brightness. Galaxy note is also much brighter so why is it that the nexus has such a dim HD SAMOLED screen?? Is it software based so people dont end up with terrible battery time??
I so so wish the nexus can have brighter screen, my biggest complaint with the phone.

Probably better for Q &A, but AOSP and vanilla Google Android has always been overly aggressive about auto brightness and keeps it quite dim more often than not. It can, and is modified by OEMs and some custom roms.
I'm not sure my screen is as dim as what other owners claim theirs to be. I have it on auto-brightness and I don't have an issue with bright outdoors or indoor. I'm not sure I'd like it to be any brighter than it already is.
Maybe I'm not used to having my screen burn a hole in my cornea.

I am talking about full manual brightness, auto brightness is never perfect on any phone but it actually isnt dim at all on my nexus S.
Dunno. I am not about to go run to Best Buy and compare, but full on brightness on my phone is uncomfortably bright in the dark and dimly lit areas, and very visible in direct sunlight.

I tried the phone at a very brightly lit shop. Put the brightness to maximum manually and yet it was barely brighter than my nexus S at 50% brightness.
Brightness isnt a contest where every phone should try to beat others but it should be sufficient enough. I just think the nexus brightness isnt sufficient, it tops out at 200 nits when the minimum should be 300 nits for comfortable use in all environments.

GSMArena and anandtech tests also show the galaxy nexus is the dimmest screen you will find in any of the high end android phones. A test done here on xda also showed the same thing.

Do you want a discussion, or do you want to discount what I am saying just to argue?
Don't ask for an opinion if you are just looking for a way to discount it.
Your sites cannot vouch for my experience.
If your phone can only match 50% of what the Nexus S can in brightness, there is something wrong with it. That or you are exaggerating. This is in my opinion, but I think it is a very valid point.
The screen seems to be limited in brightness from the factory, as a matter of settings. Using AOKP Rom and increasing the color multipliers makes the screen much, much brighter, but i've read speculation that it could cause the screen to burn-in images much faster, which logically speaking, seems to make sense. Maybe it's limited by Samsung for that reason. This particular panel seems slightly more prone to image retention than the one on my Droid Charge, granted it isn't the same as burn-in, but maybe an indicator of inclination toward it...
The GSIII probably gets 2 mins of battery life. A screen that bright on 4 Cortex A9's and 4 mali 400's at 32nm....the battery is going to SUCK.

I was not asking for opinions if the screen is dim or not but why is it. It wasnt my phone but a demo model at the shop. My experience showed me it was dim just like I had read in reviews.
I have an LCD nexus S, I am sure the AMOLED one at 50% wont be almost as bright as gnexus at 100. You know LCD's can get much brighter and the one on nexus S is particularly really bright.
I also compared galaxy nexus side by side with galaxy S2 and the difference was noticeable in brightness.

The GS3 is only 300 nits bright, it isnt anything out of the ordinary. The one X has 500 nits screen.
And nobody is forced to keep the screen on high brightness, it's just an option to have a really bright screen and a pretty good one at that.

I thought of it when you mentioned the GS2 - I had that phone for a week when it was released on Sprint, and any time the screen brightness was turned up and the screen was on for a few minutes, it would overheat and the OS forced it to low brightness until it cooled. At the time it was an issue quite a few people seemed to be having, so maybe it's limited on the Nexus for temp reasons too. As Smokeey had mentioned, battery life could be a factor as well.

Why cant I post if I dont have the device? I am thinking about upgrade from nexus S and I just made some threads about the potential issues I discovered about the device.
As long as you can see the screen who cares how bright it is. Are you trying to light up a room with it? Also, keep your phone on full brightness and you will be highly risking screen burn in so I would not recommend keeping it on full anyway even if it is not as bright as other devices.
Why would anyone purchase a phone or not purchase a phone based on it being the brightest screen out there. I can understand if you couldn't see the screen, but really? And now with the ability to change the colors and gamma of the screen, it just looks great.
So if you get the Nexus and keep the screen turned all the way up because you needed to light up your house to save money on electricity, please don't start a thread complaining about burn in.

hehe, i bought googles flagship for 450€ and i need to care how long is screen on and i cant have it on full brightness all the time becouse i "risking screen burn"?
Ah keep LCD phone on full brightness and deal with the terrible blacks. Keep an AMOLED phone on full brightness and deal with burn-in. A perfect world we do not live in.
On a serious note screen brightness matters most when going out in the sun obviously. It can never be too bright when you are out.
Does anyone else experience eyestrain with devices that have the HD Super Amoled screen?
I notice after about 10 - 15 mins of use, I get dizzy and my eyes hurt like they are being crossed or something when using the galaxy s3 or galaxy note, my old galaxy s2 skyrocket doesn't bother me though....
I've tried to turn the brightness down all the way, using the device at different distance to no avail.
Any possible solutions to remedy this? or am I going to have to sell my new S3 like I did my galaxy note? :/
depends on 2 very important factors...
1- how much cheese I've smoked
2- what was the question again?

I've actually noticed a decrease in eye strain coming from an LCD screen on my atrix. LCD screens are constantly flashing, and the screen on my galaxy s3 is super clear for me almost no eye strain. Its probably personal preference though.

I've actually experienced the opposite as my first android device was an atrix....
I think it may have something to do with the 1200 x 800 resolution on such a small screen because If I turn up the resolution on my PC HD monitor to something like 1600 x 1200 for example, my eyes start to hurt.
I was actually going to post a new great until I saw this. I came from retina displays and my eyes are sore after I look at the screen for over 10 minutes on my GS3. Kinda concerning!! Might have to switch back to an apple product. I was getting use to droid too. :-/
its because of the screen size/pixels. Your eyes still needs to be adjusted to the new screen lol... obv
Yes!
I got vertigo/migraines about a month after getting my S3. I had a number of medical tests to see what was causing it - but even after new glasses I've narrowed it down to the S3 display being too strong for my eyes. I'm going to sell mine and get a replacement with a duller screen.
Try this...
Try changing the Screen Mode to 'Natural' or 'Movie". Helped a bit.
I also immidiately noticed eye fatique after getting Galaxy s3, particularly in my right eye. It started only getting worse, and coincidently only when I was using Galaxy. Other lcd devices such as older 3gs never bothered me at all. Surpisingly majority of reviews call the display stunning quality, but its pretty dim, practically unusable outside and colors are unnaturally oversaturated, all of which didnt bother me that much as long as my eyes wouldnt hurt so much. I started reading more about specs in Super amoled technology, but nothing pointed out to potensial issues, than I googled galaxy s3 refresh rate, and the first video from the search result comparing s3 to the iphone, provided a major clue. The poor quality camera was picking up horrible flickering from galaxy, but iphone screen didnt flicker at all. It instantly brought me back to old CRT days, and I also remember getting dizzy from such displays running at low refresh rates of 60mhz. Back than bumping up refresh rate to 75mhz conciderably dicreased eye strain. I took the video to the store, sales person was suprised that I was returning such popular product, but its been a day since my exchange for another brand and eye strain is gone. The issue maybe overlooked as it affects low percentage of people, but if you have sensitive vision, than you'd be much better off with non hd amoled technology
Could it be the brightness?
I'm sure your not holding it against your nose while watchin you tube, but maybe its the overall brightness of the screen thats getting to you? I use a powersaver app that has a black screen filter that dims it out a good little bit, maybe something like that could help, or a matte finish screen protector...the anti glare ones I think.
Use the "Screen Filter" for use at nights.
Set brightness to 0, and enable filter. I set mine at 48.6% and 36.9% (created two widgets with these percentages) and use either as needed.
Set your brightness lower. It's the brightness of your screen. I have the same problem before turning down the screen

Keep phone at safe distance from face. Try a dark theme or inverted apps, or both they will most likely reduce eyestrain as well as save battery.

Hi all,
There are a lot of users who feel uncomfortable with AMOLED displays (not all of them, for example sgs2 is not affected). They can struggle with head ache and eye strain. You can google "galaxy s3 eye strain" for example or watch how AMOLED blinks through photo/video camera (there are tons of youtube videos). This effect apperars only when screen brightness is not at maximum level. The nature of that is the mechanism used for brightness control. Instead of forcing the pixels to glow at less brightness they force them to blink very fast. The faster pixel blinks - the brighter it seems to the user. The downside of this is that the whole screen blinks as an old CRT monitor which causes this negative effect.
I found an app which could help us to workaround this issue. I filed a feature request. So if you are interested you can add yourself to wathcher list and post a comment here - https://bitbucket.org/VitoCassisi/lux/issue/38/lux-auto-brightness-feature-request-for
This should not take a lot of time since you can authorise there with your google/facebook/twitter or other account.
Wow! I switched the screen to "natural", the problem with oversaturared, too rich colors was solved. I had to keep the brightness low so color pictures aren't too bright, but this made reading text on white backround unpleasant. Of course now I have to find new brightness levels (what brightness levels do you guys use for day and night?)
PS: Samsung has been doing similar tricks with the colors in their TVs. Some series 6 TVs made the picture look like it was from a heat sensor in dynsmic mode, and this was their default mode.
PPS: Mobile screens suck. LCDs have washed out blacks which strains the eyes, and AMOLEDs don't care about correct colors which makes you duzzy.
S3 screen flickers!

You are absolutely right. S3 screen flickers a lot. Try to move it quickly in front of your eyes, move your eyest when looking at it, or move your finger fast in front of the screen. I certainly do notice it.
What other phones have better displays? Sony? HTC?
I have a solution to resolve galaxy S3 scren flickering: set brightness to max in settings, install an app like "Screen Filter" (one with black-white rectangle) and decrease brightness there, in the app.
Flickering gone!

Most of phone LCD screens are not affected by flicker. Even some amoled displays too. For example old HTC Legend and galaxy S2.
Galaxy note 3, 4, Galaxy s4, 5 are also affected. I strongly recommend you not to buy any new samsung phones equipped with AMOLED screens.
Now with this https://play.google.com/store/apps/details?id=com.vito.lux software you can get rid of screen flickering issue. Automatic brightness adjust will also work.
What is the screen like outdoors?
I find the S3 very hard to use outdoors even with brightness on max. I'd read a lot of people saying this before I bought it but couldn't believe how bad it actually was.
That's always been and issue with Samsung displays.

I don't have a problem with outdoor brightness either.
No probs here too. Even when set to minimum with auto ticked, in bright daylight, the display is very clear and bright.
Cheers!!!
Are any of you old S3 users?
It sounds more positive at least.
My Note 2 has a matt screen protector which makes viewing it outside much easier as there is significantly less reflection.
I tried using my friends SIII with just the stock screen and it was like looking at a mirror, so much reflection that using it was impossible.
I should point out that I was sitting by the pool in Bangkok where the sun is extreme
Depending on the intensity of the sun wherever you are, your experience may be different.
Note's display is brighter than the S3 display by specs.
So, the other day I purchased a Datacolor Spyder 4 Pro screen calibrator. Being a photographer I want all my (primary) displays to look as natural and true to what my eye sees as possible.
So I decided to try calibrating my Gnex screen. I don't know any good way of doing this so I had to improvise, what I did is I first took screenshots of the entire calibration process and came to the conclusion that it simply shows 5 images: one solid white, black, red, green and blue image and measures it to define the accuracy of the uncalibrated screen. Then having told the calibration software that the screen has built in RGB sliders (the gnex doesn't I know, but I ticked the option anyway, you'll understand soon why) it then gives me a screen where it measures from a solid white image how much bias there is in either of the channels (red, green and blue) and gives a clear diagram overview, the objective is to adjust the RGB sliders of the monitor to make the 3 bars align (thus having no bias/tint in either channel for a natural reproduction). What I did here is that I used the color control feature available in various custom kernels (I'm using franco) and adjusted the color multipliers until' I my calibrator reported it being even and natural. I also used the RGB Gamma for some minor fine tuning.
I returned to the home screen and WOW, it's looks better than ever, grays are perfectly natural with NO GREENISH, CYAN OR PURPLE TINTS anywhere! Whites aren't perfect, leaning more toward a bright light gray, but worth noting I'm having only 31% screen brightness and I'm not sure if AMOLED can achieve a pure bright white image without a ton of cyan bias.
---
Tl;dr
Long story short, I got an hardware screen calibrator and used it to assist me get the most natural values with the color control in franco's kernel and it just pure amazing with none of the tints that the gnex is known for having.
My final values:
NOTE: These values may or may not look good for you, every AMOLED screen is different and needs different settings, these are simply the settings that worked for me, what's best for your device might be completely different!
Multipliers: 233 175 210
RGB Gamma: 1 0 1
Trinity contrast: 0
OMAP gamma: 1.0/disabled
Are the multipliers in order as RGB? Because these settings just make my screen look orangey
First thing, thank you for post:good:, i had looked for somebody to do a true calibration ever since i bought my gnex, having been spoiled before by my nexus s slcd screen, which was an excellent batch, so moving to the SAMOLED HD, for me, wasn't as great as i had hoped.
Still even after trying all the presets and fine tuning it still is slightly off.. (annoying thing with these screens not being all the same and being so different on quality, so you can't simply just input the color values and get the same result).
Anyway i like your numbers, they look pretty god on my screen.
Off topic: I'm probably wrong, but i think read somewhere that going over 200 on the color multipliers was supposed to make the screen more susceptible to burn in?

Thanks for the reply. They should be in order indeed. Note that every display is different so it may not be what's best for your individual device. Additionally, AMOLED screens I believe is said to wear/fade quite quickly compared to LCD with use and also due to the way the actual panel works in our screens each color channel will fade with different pace, effectively leading to unbalanced colors based on what you view on it; For example if you view a lot of red colors, the reds will start fading and thus everything will look a tad cyan-tinted. Finally there may be a difference in the kernel you use and the version of that kernel.
Simply put, unfortunately it's not guaranteed that what looks best for everyone else as each screen is different.
Oh, another thing I noticed; Screen brightness actually affects the color balance pretty largely. Higher brightness means less greens and more reds/blues.

And thanks to you for your reply. I actually believe I've heard someone that had used hardware to measure up the best settings for a natural 6500K color balance, but as I replied above, each screen is different and thus they were slightly too much on the blue/cyan end for me. To be honest, most settings I've tried that others have claimed to look great have always been too much green or too much blue. I've tried to adjust after my own eyes and gotten pretty close to what I believe to be good colors but always there is some kind of flaw, so I'm quite surprised to be honest I was able to get such a good overall result.
As for the color multipliers, I've heard it too but I have never seen anyone confirm it, so I'd call it off as a rumor. The burn-ins I've seen using values around 150-200 previously only apply to bright contrast colors and fades away within 2-3 seconds at most and 31% screen brightness is rather low I'd say.
---
On another note.. I just want to add that this isn't necessarily a full calibration but just an attempt to reach the most balanced color values. When it comes to gamma and contrast however I'm not sure it's really possible to mimic that of an LCD screen due to the way AMOLED handles blacks and produces very vibrant colors.

As for the color multipliers, I've heard it too but I have never seen anyone confirm it, so I'd call it off as a rumor. The burn-ins I've seen using values around 150-200 previously only apply to bright contrast colors and fades away within 2-3 seconds at most and 31% screen brightness is rather low I'd say.

On another note.. I just want to add that this isn't necessarily a full calibration but just an attempt to reach the most balanced color values. When it comes to gamma and contrast however I'm not sure it's really possible to mimic that of an LCD screen due to the way AMOLED handles blacks and produces very vibrant colors.

Actually deterioration is a problem with normal AMOLED screens. Samsung uses PenTile configuration to mitigate that in the SAMOLED and SAMOLED Plus variants. More info in the following interview with a Samsung engineer:

I put in these values using the Trickster app and my screen looked absolutely rubbish. There is no option to enable/disable Omap gamma in trickster, could that be the reason for the bad colors?

Why would the settings on his device be shown in a screen shot that you're viewing on yours?

This works very well on my phone, but I change the omap gamma to 6
Thank you again :thumbup:

He's right, smartass, the screen shot is just the source of color, no matter how you calibrate your screen, every screen shot looks the same on other devices. We can only notice with real eyes contact.

That makes as much sense as taking screenshots of different brightness levels.

You must be a genius. Never heard anyone call somebody "Captain perfect" either. Pretty crappy insult.
Glad to see some people have enough sense to realize screenshots are software rendered though.

Every screen is different, what looks good for me might look rubbish for you unfortunately :/
Also because someone asked for a before/after...
Now this will be highly unscientific and hard to reproduce but here's a before/after example (clicky for larger image):
Also advised you look at it with a good desktop monitor, and bear in mind that cameras are not perfect in any way so even if the camera settings used were identical and white balance set to match as closely as possible, it may not look to you as significant in terms of differences than it is to my eye. Nonetheless I can certainly see a difference especially in the gray and white tones.
The before example is not the stock kernel but simply the reference settings of all multipliers set to 200 and RGB gamma all set to 0. I believe this should be fairly similar to what stock kernel shows.
Still looks orangeish to me so I lowered red down to 220. But thanks anyways. I always love testing these.
A screenshot won't show screen adjustments...

You had a green tint before u changed it. I can that in the Google Search bar.
And what's funny is the color u recommended are extremely similar to mine lol.
*Multiplier*
Red: 235
Green: 170
Blue:206
*RGB Gamma*
Red: 4
Green: 0
Blue: 2
Trinity: 0
Omap:1
But yeah I had a very greenish tint in my screen. Made my keyboard look brown before I rooted. =|
