FYI:

I have a the yellow side problem (pic is somewhere in this thread) and my LCD type is: OCTA : SM2.

My IMEI is: 355310043187578
[Galaxy S II General] stijnr:
Wasn't the banding caused by the fact that the software is currently running with 16 bit color depth? I'm quite sure it is a software issue, and hopefully it will be fixed at some point.
[Galaxy S II General] Spik3balloon:
If there weren't enough pictures in the thread already, here's some more proof. Second picture, I turned the phone 180 degrees in the same spot to make sure it wasn't a lighting/camera thing.

Also, I'm not sure if it's just mine, but the colours on my GSII seem to be significantly colder than any other device in my house (there's a bluish hue to everything, especially prominent when the environment is completely dark, and I'm viewing white - see 3rd picture) Anyone else have this? Edit: as below, it's an OLED thing.
[Galaxy S II General] renton82:
Is it really possible?

So i'm not sure to try to change the device, i'm afraid that the shop owner think i'm crazy...:D, i think that all devices have this problem, i think it's part of samoled+... If u want a samoled+ i must accept this little bug
[Galaxy S II General] Jade Eyed Wolf:
The cooler blue colour temperature is a function of OLED technology in general. Blue is the hardest colour to reproduce, and it also has the shortest lifespan compared with red and green. That's why all (S)AMOLED(+) displays have been biased more towards cooler temperatures, because with time the blue will be less intense and the overall colour temperature will "warm up" if you will. My GS1 looks much more natural now after a year of use. Just give it some time ;)
[Galaxy S II General] Spik3balloon:
Ah, I see, thanks. Fair enough. Looks like I've never been noticing the subtleties of using Voodoo Colour-based kernels on my original Galaxy S. :)
[Galaxy S II General] rudolf895:
Just brought mine... Haven't noticed this..

Could some one tell me steps to reproduce this?
[Galaxy S II General] vinaymonu25:
to all

please help me guys plz tel me if dis leftside screen problem can b fixed or not. I mean its not a hardware problem right ? I didnt buy it yet coz of dis..wt u guys say shud i buy nw n c dat further updates wil solve it or wait 4 any software updates to solve it then buy it or just wait 4 any hardware changes in screen ?
[Galaxy S II General] Ibb1982:
I have this issue with yellow tint, but its not noticeable under normal use, only apparent with the grey background in op.

I have the lighting issue too (left side darker than right) again very minor.

Will post pics later.

LCD type : OCTA : SM2 (A1 line)
[Galaxy S II General] renton82:
Is there any possibility that the problem is related with the glue like iphone 4 and disappears in some weeks?

Maybe we can dry it with hair dryer! :D
[Galaxy S II General] ximikos:
maybe....anything possible
[Galaxy S II General] Natascha303:
I will do the LCD Code instantly, hold on.

Just another NEW comparison from the old "good" one and a new fresh phone.. which one do you prefer? It's really annoying when you compare 5 deveices and see the difference.

Left one hast more contrast and for example more black and more blue, more instense.

Right one is the "good" one from my last comparsion. It is at the same settings much more brighter than the left one, but not as strong blue, black, green colours, look at above.

Yellow, Green one batches have MORE powerfull coloures! really.

None Yellow ones are brigther, whiter.

So whats better ?

[Galaxy S II General] Robsso:
While I think it's hardware related (haven't read the whole thread so maybe someone has already confirmed that) it's, for me, absolutely insignificant thing.

I was thinking about to buy this phone twice after I read this thread (and other GSII issue related), but I bought it anyways and I'm glad now. There's pretty high chance that if it wouldn't be for this thread, you (at least I definitely) would never notice this issue.

Although I was able to replicate the issue based on guidance here, it's not obvious at all and apart of this test, I don't see it at all even if I try to focus on it ( I rather not though :) ).
[Galaxy S II General] afterdarq:
Is the problem getting worse or better over time, can anybody say. I remember one post saying it is maybe getting worse, but has anybody else noticed any progression?

I am also thinking of buying the phone, but this thread really made me stop and think about it. I know it is a great phone despite this screen issue, but I will have to pay a lot of money for it and therefore it must be trouble-free.
[Galaxy S II General] ximikos:
my photos
[Galaxy S II General] powerba11:
Maybe they adjust somehow(hardware) the setting, setting the brightnes level to a higher minimum...thats why the second one is brighter(with the same settings). As we all know the yellow band is more visible on 10-20% brightness. But I think the second screen is not very different from the first one...I can see difference of left&right sides of the brighter screen.
[Galaxy S II General] Natascha303:
http://www.lagom.nl/lcd-test/gradient.php

banding is on all 5 batches, so dont worry.

i took all pics and vids at about 20-30% brightness.

i just using the 2 best of all for a week to see if anything gets better, worser. but i think i will keep the brighter one, also better for the battery.
[Galaxy S II General] Natascha303:
.....octa:sm2
[Galaxy S II General] jvidia:
As time passes, even not using it during the day (just toy with it at home at night), I have the feeling (I could be wrong or becoming used to it) that it is getting better.

Lets pray that it is a "glue thing" or the organic leds are "maturating" or something (I'm guessing here off course :D), because I have almost certern it's not a SW problem.
[Galaxy S II General] ithehappy:
Oh if that's true then it's a big relief..
[Galaxy S II General] blade75:
same as mine...
[Galaxy S II General] Pfeffernuss:
Wishful thinking.
[Galaxy S II General] Natascha303:
all of mine have this version.

But all have other coloures, tints and so on ;)

do you also have some camera noise when starting the cam ?
[Galaxy S II General] ximikos:
yes....same noise here!tak tak....

dont worry...no problem
[Galaxy S II General] blade75:
Uhm...then the ID of the display itself is not helpful to find an explanation

yes. definitely. I think it is normal and related to some mechanical movement.

Instead i have the pink spot/alone on white, but there is another thread for this
[Galaxy S II General] technetium99m:
...

My images - there is one taken at 20% screen brightness and one taken at 100% screen brightness. Just in case there isn't enough images on here already :p.
[Galaxy S II General] nomnompie:
The camera "click click" is normal. I am pretty sure its mechanical in the lense as I had this on my HTC Hero as well..

If someone wants to try the hairdryer thing, by all means do, but carefully. I already tried this (:D) on the front of the screen but I do not think that the heat was able to reach the screen. Maybe if you take off the battery cover and remove the battery and aim the hairdryer at the back it may help. I was too chicken to try this because I didn't want to be dumb and melt something.:o

Jvidia how long have you had your phone?
[Galaxy S II General] eallan:
I'm sorry but that is just not true.

The notification shade is "normal use" and one of the easiest ways to see the issue.

I noticed it using the XDA app without hearing about this thread. I wouldn't have titled the thread "yellow" though.
[Galaxy S II General] godutch:
I don't see the yellow left side when using the xda app but I see the banding on the splash screen though
[Galaxy S II General] eallan:
It's not the yellow i see, but a subtle gradient of brightness.

Makes my brain go nuts like i'm seeing things haha.
[Galaxy S II General] jvidia:
The camera "click click" is normal. ;)

Since 25th of May, but as I said previouslly I only use it at night :D
[Galaxy S II General] r_a_c:
There is a topic abouth the blue hue.

But also could you check if you unchecked this option

options-->display-->automatic screen saving power(i don't know it in english, but you get it when you see this option:p).

It seems like this is still on. Mine looked like it when it was on, turned alot whiter when it was off. This option is turned on stock, really stupid move.
[Galaxy S II General] BarryH_GEG:
From what you've shared, sadly, I think you got one of the ****tier specimens. The best hope is that there's a production change that addresses the issue so you can send your phone in to get its screen replaced. I'm going to Korea next week so I'll try and do some screen comparisons when I'm there. Once the Sprint version lands in the U.S. we'll be able to compare screens and see if a new variant brings with it any changes. Also, those in the U.S. can get there screen replaced in the U.S. by Samsung under the Global Warranty once it arrives.
[Galaxy S II General] eallan:
Both of mine were identical, and from different batches. Perhaps my eyes are more acute than others.
[Galaxy S II General] J.2K4V:
I dont seem to have this problem, I would take a picture with a camera but it doesnt come out quite right..i normally use my phone to take pics but anyway doesnt the screen have a funny effect when taking a picture with a camera...like in most reviews theres this 'wavy' sort effect on the sgs2 screen.

Does the build info tell me what batch my phone is??
[Galaxy S II General] BeelzeM:
Maybe a really stupid remark, but wouldn't it be possible that Chainfire himself or someone else makes a plugin for CF3D that reduces this. Kind of like the Nightmode but it reduces the values of yellow on the left side of the screen. I've checked a photo of my screen in Photoshop and it has more yellow values on the left side in the notificiation tray. Obviously some screens are worse than others. Maybe a slider that reduces the yellows slighly on the left side in a gradient way so they mix to the point where it's not visible anymore?

My screen has the same issue, not as bad as others but I can see it when the brightness is down.

Again, this is just a thought and probably totally stupid, I don't know how screens technically work.
[Galaxy S II General] -Anthony-:
Hi guys,

some official news by samsung about this issue?
[Galaxy S II General] Natascha303:
so which one do u like more ?

isnt the right one almost to bright ? the contrast on the left is much better, dont u think so ?
[Galaxy S II General] janny_buh:
Much better the right one in my opinion, gray background seems definitely more "gray" :o

The right is your fifth device (the most recent), isn't it? How can we find the batch number (or something similar) in order to find most recent devices?
[Galaxy S II General] Natascha303:
Three SGS2 comparsion

Which one is the best ?

I dont know if i should choose the middle one, of course, no green,yellow at all.. but it's that bright, it almost tends to red?

The left one is which most contrast, but darker!

Remember, all same settings.

further problems:

left has got a clicking noise camera, middle has got a not proper display insert ( one corner of the glass is a bit higher than the other sides ) and the right one is this with the yellow stuff, but rest is fine.

thanks for opions.

[Galaxy S II General] stijnr:
I think the middle one is best. The grey is the most "grey" of the three. The right one has pretty visible yellow discoloration on the left side.

The whites on the center one are also better, the left and right one are blueish. The colors (in the last pic) look better too, brighter...

I think the center one is perfect, and I would definitely prefer it over mine...
[Galaxy S II General] r_a_c:
This is too funny...

We are discussing wich sgs2 is the best out of 3 phones that 1 person has... For a flagship phone, this is insane...

And it's not that it's not obvious, they are just 3 different screens. Samsung made a totall mess... damn it!
[Galaxy S II General] -Anthony-:
Comparision

I chose the middle one. Grey a lot "strong" going to red, but browser seems to be ok.

How ca I do to chose a model with these features?
[Galaxy S II General] r_a_c:
Can you check options--display--- automatic screen power adjustment(don't know the exact english word for it but you will see it) and see if this is checked out on all 3 phones.
[Galaxy S II General] r_a_c:
LOL, these are the exact same phones(or should be...).
[Galaxy S II General] Natascha303:
nothing, it is just luck which one u get. these 3 are best out of 5.

BUT the beat goes on...

middle one has a ****ty display glass, one corner, there is the glass over the side of the phone. :rolleyes: every phone has a drawdown, u have always to choose one failure, to live with. camera,display, bulid quaility...
[Galaxy S II General] Natascha303:
@rac

i promise you 100% same settings and also this power option unchecked.

anyway, the middle one looks even more like a SLCD Display = better white and grey=grey. But it almost goes into red, it is much more bright than the other two. I would take it, if the display glass would be OK. but so...
[Galaxy S II General] Spik3balloon:
This option was checked, but turning it off seems to have no effect whatsoever.
[Galaxy S II General] -Anthony-:
I know it :) I wanted to know the serial number or about so
[Galaxy S II General] nomnompie:
Agreed.. It shouldn't be that hard to get your hands on an 800 dollar phone that is actually worth 800. Mine is going back. Going to have to use my painfully slow HTC Hero a bit longer. Whether I buy the SGS2 again will be determined if I start hearing something being done about this, or other variants/batches not having the problem.

Shame that Samsung can't seem to make a device without screwing up some aspect of it. This phone was perfect, if it were not for the "crap stain" on the screen. First it was the GPS in the GS1, now poor screen quality in the SGS2.

Was impressed at first, but not anymore.
[Galaxy S II General] eallan:
I was told when they examined my first phone that the screen was fine and all the tests passed. They replaced it as a courtesy...
[Galaxy S II General] Bratag:
I just sent my unit back to expansys for replacement. Worryingly the yellow/darkening seemed to be getting worse and I could no longer live with it. It sounds like stock levels are high so with luck this will be the second round of manufacture and the issue will have been resolved. If not I will be, to say the least, unhappy.

Phone should arrive tomorrow. I will let you know what eventuates.
[Galaxy S II General] eallan:
Photos please!
[Galaxy S II General] Deviser:
Last year Apple had a problem with screens in the iMac line. They also had a yellow tint. Somebody said this about it:

I know the Galaxy S II uses an SAMOLED without backlight, but could this be related in any way?
[Galaxy S II General] eallan:
I don't see how.

I think the other theories of: Screen manufacturing process (heat treat, coating, etc) or voltage across display are more likely.
[Galaxy S II General] BarryH_GEG:
+1. And until one of the above changes, I think all the phones are going to be effected to varying degrees.
[Galaxy S II General] Deviser:
Maybe a defect between layers of the screen, or the screen and the glass. Funny that it happens always on the same side. Anyway, this has to be a production issue and it won't be solve by software.

It's a shame that Samsung won't say anything about it. I guess they hope most people won't notice it.
[Galaxy S II General] BarryH_GEG:
I've got it (I think we all do) but don't see it unless I take a picture of my screen. As anal retentive as XDA'rs are, the hue and cry would be much louder if it were visible in everyday use. And this thread has been on the front page almost from launch so it isn't exactly a secret. From pics posted there seems to be big variations of both the issue and general color/contrast across multiple devices. So who knows what percentage are "bad" and what percentage are "good" based on people's individual devices and expectations.

As a comparison, the OP (who seems to be long gone) made a point of alerting the media of the problem. There were two references made; one on GSMArena and one on Engadget. Compare that to the Sensation death grip issue which has become a huge and ongoing spectacle across multiple media channels. If the SGS2 screen issue was truly as bad and prevalent I'd assume it would have become a much bigger cause for the media. The Sensation death grip effects everyone equally and impacts every day use. We can't say the same for the SGS2 screen issue (although that doesn't help those impacted).
[Galaxy S II General] eallan:
Expansys said they would use their french branch to ask samsung for a response on this. Can't hurt :)
[Galaxy S II General] BarryH_GEG:
I have a friend in IT at a big Sprint corporate account. He's supposed to get some Within demos to play with soon. I'll compare screens and take some side-by-side pics to see if anything's changed.
[Galaxy S II General] sachilleas:
Guys this phone is a mess.... It's full of bugs. Yellow tint, Pink spot camera and the circle screen problem.It's impossible to find a single unit without these problems .

I've experienced all of these and all i can say is i regret buying it.
[Galaxy S II General] Erethnor:
Not gone at all, just lurking as I do not have any news. And waiting for my replacement unit since longer than 3 weeks now, definitely not impressed with the time samsung assistance is taking.

Will of course post as soon as I have my phone back, which will be interesting as I believe I'm the first to hand it in for repairs.
[Galaxy S II General] eallan:
Well here is hoping that they're checking your issue out and learning.
[Galaxy S II General] BarryH_GEG:
Welcome back! It's great that yours is being repaired by hand. If in fact the problem is in the mass assembly process, and your new screen is flawless, sending the phone in for repair will be a viable option for people.
[Galaxy S II General] Crazy CS:
Any point returning the handset when the next one could be worse?
[Galaxy S II General] :
If it problem is in mass assembly process, it will take a huge time to repair this. You just don't change assembly line mass production systems overnight. The decision itself to change it might take weeks/month.

So realistically (if) the issue is with mass production systems, I would expect better/modified batches start rolling out maybe in 1-2 months.

EDIT: This is assuming Sammy is indeed going to change it. Cost for changing the assembly line vs loss of sales because of this screen problem. It's a mess, and I can't even imagine how many meetings before anything changes.
[Galaxy S II General] SkullDeath:
In addition to the yellow tint on the left side (circled) did anyone notice the discolored vertical bands on what is supposed to be a uniform grey notification area. I get the same thing on my phone and this effect is also visible on launching the XDA developers App (with the dull brown / orange background on the splash screen) as well as while loading another thread within the app when the screen dims with the white background.

I don't have a good enough camera at hand to take a picture of it (the above picture is from Engadget mobile).

So are the discolored vertical lines also a feature of the world's best display technology or did I really get a bad screen with all the kinks in SAMOLED+?
[Galaxy S II General] briko78:
NO - definitely NOT. Return it.

GOSH Samsung - what have you done????
[Galaxy S II General] Jade Eyed Wolf:
So, apparently mine has the screen issue as well, but to be totally honest, for me at least, because I know everyone feels differently about it, but for me it's really not that big of an issue at all. Either that, or I just lucked out and got one where the screen issue isn't as apparent as it might be on other phones. I keep my screen at about 50% brightness most of the time anyway, and the problem goes away for me then. I don't have a picture hosting site for the images though, so if you want to take a look, PM me and I'll send them to you.
[Galaxy S II General] bazzztard:
Nope, not the first...but to tell you: they replaced my screen, the s2 went trough QA and i got it back (after almost 3 weeks):

My "new display" SGS2, WITH yellow tint again (but not that strong the first display had it) now also sounds like something is loose in the upper back area (around the camera). I can hear that by knocking on the upper back area or just while putting it on my razer mousepad =/

edit: mine got "repaired..." by the german Samsung service
[Galaxy S II General] powerba11:
Probably the yellow tint is the result of some interference.

Maybe Samsung has just tested the screen outside the phone, before assembling the phone...and the screen has passed the quality test.
[Galaxy S II General] uiterlix:
Unless you're really into swapping your phone all the time for a new one to find out it has the same problems. Mine has the yellowish left side too, and it also has a little brighter dot at low brightness. But I think it's more sensible to wait a few months and have it repaired once the production issues have been sorted out and resolved by Samsung. You have a year's warranty anyway, and it's not that bad that you can't use the phone. It's not even noticable when you increase the brightness to a level above 30/40 percent.
[Galaxy S II General] Bratag:
New phone back from Expansys. Can confirm a darkening on the left side. Not as bad as the previous phone however. May just live with it.

Sigh
[Galaxy S II General] derby_sv:
What do you think about the rumor that yellow tint appears as a result of the local overheating because of incorrect working the firmware based on Gingerbread 2.3.3 on dualcore CPU?
[Galaxy S II General] icet69:
I've seen a new one in a store of a local dealer. The phones arrived yesterday. The problem is still there :-(
[Galaxy S II General] DaviD202:
i have octa : M2 wtf??

anyone has "m2" ?
[Galaxy S II General] julandroid:
It seems some of you have really a lot of issues and I hope all of you will be able to get a better replacement.

It is a scientific fact that the human can see best the yellow colour which make this issue annoying for those affected. Human vision is amazing - It can recognise and distinguish about 13 million shades and nuances of colour, which means that an even an extremely small difference in the colour precision (i.e. to divert from the standard) can be detected from the human eye. Display business is a tough business :)
[Galaxy S II General] Leggenda:
Sorry for my bad, bad English ...

However, today I found something very interesting.

2 months ago I bought a brand new GS1 and I upgraded to 2.2.1 Froyo.

When I discovered that the GS2 had the darker screen on the left, I checked if the GS1 had the same defect, but it was perfect.

I also went to the site linked in the first post, but the grays were perfect everywhere, and the display were not darker on the left.

Today I decided to upgrade to 2.3.4 my GS1 ... and here is the surprise!

After the upgrade, the notification bar is much darker on the left than the right (same defect of theGS2) ...

Now I have to go out, but as soon as I get home I want to go to the site of the first post also from GS1 and see if now is seen as bad as the GS2!..
