Thanks for posting this. As soon as I read it I remembered that the Nexus S ran into screen problems when Google released 2.3.3 because Google had made changes to the colour temperature to fix other colour related problems:

http://www.tgdaily.com/mobility-brief/54366-nexus-s-gingerbread-update-messes-up-screen-colors

"So in the 2.3.3 update, it changed what's known as the color "temperature" on the device.

In so doing, however, it managed to mess up other color tones, leaving a yellowish effect in place, although the gray-red problem has been resolved."

[Galaxy S II General] ithehappy:
Oh yes, now I am having a good hope on 2.3.4. So this problem could be for 2.3.3, right? I'll take it as a yes for peace of mind :D
[Galaxy S II General] jvidia:
That could explain the massive number of devices with the yellow tint effect.

And explain why Samsung haven't said nothing yet.

Let have hope.
[Galaxy S II General] DuoM:
Lol. Well we can only hope.
[Galaxy S II General] Leggenda:
Ok, but in our case (with GS2) the problem is not of entire display, but only the left half... do you agree?
[Galaxy S II General] Leggenda:
In my opinion you're wrong, because with GS1 with 2.3.4 the problem is evident (read my post)... so, in theory there is also on GS2 with the 2.3.4...
[Galaxy S II General] DuoM:
Yes, I agree. However in Leggenda's post he said that an upgrade from 2.2.1 to 2.3.4 on his GS1 introduced an issue with the left side of the notification bar being darker than the right, which is one of the reported problems here so it could be that one or two of the reported problems in this thread are related to the version of Android.

Hopefully he will be able to provide more information when he gets home.

Anyone want to downgrade to 2.2.1 to see what happens?
[Galaxy S II General] DuoM:
Did you use an official Samsung upgrade to 2.3.4 or was it a user created ROM?

The Nexus S was affected quite dramatically by the changes in 2.3.3 so I'm wondering whether Samsung have done something special with their new ROMs (2.3.4 onwards) to alleviate this problem or will users have to wait for 2.3.5 or 2.3.6 for a fix from Google.

Edit: Just realised that Samsung can't make changes to the Nexus S ROM to fix the problem since it is supposed to be a pure Google device but they could do for ROMS for other devices.

[Galaxy S II General] BarryH_GEG:
There's two different discussions going on.

1) People were complaining about the blueish tint on the Nexus S so Google changed the color temperature and it pissed everyone off. It effected every device, every screen, and every user equally. Samsung could re-calibrate the colors on the SGS2 also. It would effect every device, every screen, and every user equally.

2) The more interesting post that I'm anxious to see pics from is a GS1 with discoloration on its left side after being upgraded to 2.3.X. But don't you think the millions of GS1 users on Gingerbread would have noticed if their screens suddenly were discolored on one side after the upgrade? It took the OP about an hour to discover it on his SGS2. It would be fantastic if the issue ends up being software then even if its not corrected in 2.3.4. there's hope that it can be corrected somewhere down the road. It's too early to get excited yet based on one undocumented report.
[Galaxy S II General] BarryH_GEG:
Leggenda, do you post in the SGS forum? If so, can you ask over there and see how many others pick up on what you've detected?
[Galaxy S II General] jvidia:
Leggenda, now the best thing you could do is to take some photos of your GS1@2.3.4 and then downgrade to your previous Andoid version (that was OK) and take some photos again, to show us all that your theory is real. ;)
[Galaxy S II General] DuoM:
A quick search to see if there had been any progress made on the 2.3.3 colour issue in 2.3.4 wasn't encouraging.

However having read through a number of threads on the Nexus S SAMOLED 2.3.3/2.3.4 issue, with people complaining about terrible colours and a yellow tint to the screen, I am now wondering if people with the Galaxy S II aren't actually seeing a single issue with the displays that is being partially masked by the colour change that Google made in 2.3.3 and the steps that Samsung took to deal with the effects of the change on SAMOLED+ screens.

Could it be that there is just one issue, an attenuation issue or an interference issue that makes part of the screen incorrectly appear lighter or darker in certain areas depending on what is being displayed and when the screen is particularly dark the yellow tint is visible in just the dark part? That is to say if 80% of the screen were at the correct brightness but the remaining 20% in a band on the left side were at an even lower incorrect brightness setting perhaps the yellow tint shows through then.

It could be even simpler than that, it could be that the colour temperature of the screen is not being evenly maintained across the entire screen, which could be a hardware issue but it could also be a software issue.

If what some people have written below is correct then Google have said that they aren't going back to the old colour scheme so perhaps Samsung have already made adjustments to the display settings to deal with the new colour temperature on SAMOLED+ displays. However it is possible that another problem (attenuation/interference/software?) is causing the screen to not display as it should across its entirety.

Just a thought.

http://www.google.co.uk/support/forum/p/Google+Mobile/thread?tid=5f068ce3faca3f9c&hl=en

"Sorry guys, they've told us to sod off, they're not going to give us a manual fix. And seeing as the new colour is how they wanted it, it's unlikely they will revert back in the next update. I think the crap they've been spinning about how it would be potentially "damaging" to the hardware is a clue that they won't even try to go back to 2.3.2 colours. Really pissed off about this - only thing to do is to continue to get the message out there about how google treats its customers"

"I updated to 2.3.4 and the colors are still washed out. The yellow tint is still there :(

This sucks!!!"

http://www.google.com/support/forum/p/Google+Mobile/thread?tid=75dc169e10c20b97&hl=en

"I just upgraded to to 2.3.4 from 2.3.2 and now the colors look washed out and have a yellowish tinge to them. I greatly preferred the sharp contrast between whites and colors that this phone originally displayed. Now my super amoled screen looks like it got baked in the sun for 12 hours.

Google, please revert back to the original color scheme."

[Galaxy S II General] Leggenda:
No problem! But you should wait few hours because GS1 is of my sister and she's gone out... :P

However, i'm absolutely SURE that before upgrade, display of GS1 was very perfect in every corner. ;)
[Galaxy S II General] jvidia:
thanks mate ;)
[Galaxy S II General] DuoM:
OK. Thanks.
[Galaxy S II General] Flowlance:
Can anyone downgrade to froyo to see if the problem is there?
[Galaxy S II General] jvidia:
Is it possible on the S2 ??
[Galaxy S II General] Crazy CS:
Ive noticed on a grey screen when i rotate my screen horizontally u can see the marks of the notification bar sunk into the screen. Anyone else have this?
[Galaxy S II General] jvidia:
Like a burn-in effect ? Yes it's normal.
[Galaxy S II General] Crazy CS:
That is so bad..... Is it an issue with the oled?
[Galaxy S II General] jvidia:
Unlike displays with a common light source (ex: LCD), the brightness of each OLED pixel fades depending on the content displayed. The varied lifespan of the organic dyes can cause a discrepancy between red, green, and blue intensity. This leads to image persistence, also known as burn-in. As I said it's normal to the OLED tecnology.

It's similar to the plasma TV's ;)
[Galaxy S II General] Crazy CS:
Righteo. Did the GS1 and NS have the same oled issues?
[Galaxy S II General] Leggenda:
Pics of GS1 display.

Left side a little bit darker than right...
[Galaxy S II General] jvidia:
From that photo it's quite unnoticeable.

Are you going to downgrade ?
[Galaxy S II General] eallan:
Seems pretty obvious to me.
[Galaxy S II General] nomnompie:
Something I thought worth asking: On that SGS1 Where is the dark spot when you rotate the phone? Does it stay in the same physical spot of the screen or does it rotate with the orientation of the phone?
[Galaxy S II General] Flowlance:
If it's a hardware problem it probably won't rotate lol
[Galaxy S II General] BarryH_GEG:
You are kind of a super user when it comes to spotting display stuff so I trust you when you say you see it. Based on the pic, do your really think the SGS2 issue could be software?
[Galaxy S II General] Silver420:
I've had my S2 for under a week and thought I was going mad at first with the colour being slightly different on the very left compared to the right. I've just spent the last hour reading this thread and cant seem to find any hopeful news. (Unless pics are posted of the supposed S1 with and without problems on various firmwares)

Like others have said, I dont want to return it, and get one back which is worse as tbf mine is not as bad as some of the pics I have seen. At the same time, it would be nice 100% to know if this was a software or hardware fault :confused:

I believe its hardware though i would LOVE to be proved wrong. *waits for more news*
[Galaxy S II General] eallan:
Not a chance. I wish it was :/
[Galaxy S II General] nomnompie:
My point exactly. :D

We're talking about the possibility that it's a bug with GB on the S2.. yet, the tint is always on the same spot on my S2, so I do think it is hardware, not software, unless the GS1 issue being talked about, happens to not rotate, well then, I would be kind of surprised because that wouldn't make sense lol.

[Galaxy S II General] sul911:
Hi

For me the tinting is more visible on white backgrounds but when I play a video I can not see the tinting at all evem at pause. Any one can confirm this ? And does that mean its a software problem ?

Edit: I notice decrease in tinting :s or my eyes got used to it.
[Galaxy S II General] blade75:
Just a little. I can see it. For thos who can't, a did a little editing of the image flipping the bottom half.

Could you do the same with the complete gray background, and then downgrade to froyo, so we can compare gray@gs1@froyo with gray@gs1@2.3.4 :D
[Galaxy S II General] executiverocker:
My sgs2 was bought end of april from phones4u and genuinely does not have this fault!
[Galaxy S II General] DaviD202:
what type of screen u have?

I mean "call" *#5238973# and write down what u see there.
[Galaxy S II General] jvidia:
Leggenda, any downgrade yet ? :D

blade75, that diference could not be from the angle of the photo was taken?

The real yellow tint problem is not so uniform/fade out.

[Galaxy S II General] Crazy CS:
Look at the right edges they should be bright white then look at the left they are dark yellow
[Galaxy S II General] Natascha303:
which one to choose ? cant make a decision...

right one best white and grey

left one better contrast and colours

http://www.abload.de/image.php?img=sdc108580tjd.jpg
[Galaxy S II General] jvidia:
I'll go for contrast ... left.

The right one looks SLCD :D
[Galaxy S II General] Natascha303:
thx

but i have to take two-three "ticks" more to get on the same brightness like the right one... isnt that much more bad for the battery ?
[Galaxy S II General] connectandroid:
hmm could be then again the left side is facing my wall which is in fact yellow/creamy colour :)
[Galaxy S II General] Natascha303:
But maybe he saw a modell which was just to "fresh" ... i mean, the yellow stuff is getting worse when time goes on ?

Anyway, maybe someone can post a picture of a PERFECT one ?

As im writing in an other forum as well, and there are plenty of "faulty" ones too... if this is really a fault. Because SAMOLED also has got variations like red,green, blue tinty displays... just luck which one you get.
[Galaxy S II General] __NBH__:
I don't have the yellow problem down one side of the screen so I would advise anyone not hapy to try to get a replacement but once when the battery was quite low, around 10% the whole screen suddenly got a bright red tint to it. I thought it was the game I was playing but the home screen had it too. I had to turn the screen off then back on and it was back to normal. It hasn't happened since but worried me as I thought it was broken
[Galaxy S II General] eallan:
Mine was yellow the moment i opened it. I'm not worried about it "appearing over time" so much as I am having a clear display to start!
[Galaxy S II General] eallan:
Can you snap a few photos please? Preferably with a grey background?
[Galaxy S II General] jonny_ftm:
I'll take shots of mine with the drop down menu and the page here:

http://fiddle.jshell.net/qFxsC/1/show/

I'll test at 20% brightness and maximum brightness in dark room

Will post the pics
[Galaxy S II General] jonny_ftm:
20% brightness

100% brightness

20% brightness

100% brightness

Pictures were taken with a DSLR camera, at 20 and 100% brightness

Auto Brightness and Auto Power LCD were disabled

The little ghosting, un-uniformity and tints on pictures 3+4 are chromatic and optic aberrations in my opinion as taking pictures in these conditions, even with my DSLR is hard. I don't see those aberrations on the real display with my naked eyes
[Galaxy S II General] Natascha303:
Thx for the pucs johnny,

But i have to say it looks also yellow tinty, maybe our mind is justgoing crazy because of the pics which increase the "yellow look" ?

i mean i do see also some yellow on my modell, im just wondering people getting replacements and the luck for a new one with absolutely no tinty?
[Galaxy S II General] jonny_ftm:
The captured pics are yellow because of the white balance

Below is the non cropped version of the pic 3 from my previous post

You see the background ?

Guess the real color of it? White!!!!

Also, look at my battery gauge: it is yellow while in reality it is green...

This is with a 17-55 L quality lens on a 550D canon DSLR

Yes, I could adjust the white balance, but I didn't, as most here won't do and because I don't see any screen defect in my eyes, just like I see the background white while my camera see it reddish

So, all pictures taken in very low tungesten light are yellowish unless you manually calibrate the whites before you take pictures
[Galaxy S II General] eallan:
Honestly, I still see it. The left side is "darker" than the right. Forget about the yellow issue and look at the brightness maybe?
[Galaxy S II General] r_a_c:
The left side is just like the problem we are talking abouth,sorry. Strange you don't see it. Makes me really wonder if there are examples without it. As most people who clain they don't have it still gor it.
[Galaxy S II General] eallan:
Crossing my fingers on a spotless replacement!
[Galaxy S II General] jonny_ftm:
All I must say is that I don't see it on the real screen. Just the shots show an uniform pattern, for me just due to the picture shots and low light conditions leading to chromatic aberrations. Sad I can't show you the real screen :(. Whites are uniform, grey too, even the OLED test screens via dialer code

Will have to monitor the screen on the long run to see if it shows slowly on the OLED, but for me it is a keeper

Will let you know if something comes out. Cant RMA a unite when the naked eye of me and my wife see it perfect!!!
[Galaxy S II General] TechNoir:
Thanks alot for the pictures mate. I suppose some phones are milder than others, and photos can exaggerate contrasts or color alot.

Just for clarity sake, I did some minor editing to your pictures:

http://imageshack.us/photo/my-images/263/h7ivzam3y97ek9eg81img40.jpg/

http://imageshack.us/photo/my-images/853/h7ivzam3y97ek9eg81img40.jpg/

One of them I simply increased the contrast, and the other one I increased the green and yellow color saturation uniformly for the image. Again just to visualize that there is a difference between the left and right side of the display.
[Galaxy S II General] Rural:
I have detected a slight yellow tint at the left side. Visible on dark gray with low display brightness.

It's not much, it does not disturb and I think I can live with it if it doesn't get any worse.

Can it get worse? In that case, can it also get better?

Could new graphic drivers fix this?

I'm thinking of my former TV which had a blue tint, that disappeared automatically.
[Galaxy S II General] giannisr7:
That's the million dollar question for most of us that have the yellow/darker tint on the left side of the screen...Should we wait just in case it fixes it self after a period of time like in iphone's 4 yellow spots, is it permanent? I don't know what we should do.....:confused:
[Galaxy S II General] quattro_rs:
i too have this yellowish tint on left side, but its barely noticeable in fact if it wasn't for this post i never have noticed it .

do you guys think it can be fixed via software ?
[Galaxy S II General] eallan:
I don't see that being possible. It's got to be some flaw in the manufacturing process.

I left my screen on white high brightness for like 5+ hours the day before i sent it back to see if it would help.

It did not.
[Galaxy S II General] jonny_ftm:
Thank you for your post

I see what all people here mean, still disappointed as I can't see it on my LCD screen compared to the photos I shot... :confused:

I'm also used to photos showing different things than the eye because of many aberrations/distortions related to lenses, and that's especially in extreme conditions, typically low light with high ISO.

If it ever shows to my eyes, I'll put a feedback. Definitely, if it was ever showing to my eyes like some photos posted by other users here, I wouldn't hesitate to RMA the phone for the price of it :mad:
[Galaxy S II General] TechNoir:
Yeah, if it isn't bothering you I wouldn't bother with RMA, especially since atleast more than 1 phone have these characteristics. If my replacement one has the same thing I will just go with it and keep tabs on the tint to make sure it doesn't worsen.
[Galaxy S II General] jonny_ftm:
Well, a small feedback.

I redid the testing this time with LCD in total darkness and not very low light like before. The grey web page in post 1 indeed let me see some darker/yellowish gradient from left to right. Only apparent in dark for me and really very light. Won't ever noticed it if I didn't follow you here. Again, it will be a bit evident in the dark and low screen brightness. In very low light it didn't appear in my case, and by very low I mean such a low light I couldn't read a paper... Only in rather dark conditions
[Galaxy S II General] DuoM:
As I've said before cameras can see things that are beyond the range of the human eye.

What matters is whether you, your friends, family and colleagues, or anyone else you ask to check the screen with you can can see the tint when the phone is setup in the way that makes the problem the most obvious (brightness, etc) and when the screen is displaying whatever makes the problem the most obvious.

The phones are not made for robots or cyborgs, it's what can be seen with the human eye that matters. If it can't be seen then the phone is fine.

If it can be seen and if it bothers you, DOA it and either get a new one or get a refund and wait for a bit to see what happens.

If it can be seen and if it bothers you and you just hold on to the phone you are decreasing the chances of Samsung fixing this fully in production - kind of like all the people who held on to their SGS despite having a problem with the GPS which bothered them but hoping for a fix. Whereas one million returns worldwide due to a faulty GPS would have gauranteed a fix.
[Galaxy S II General] eallan:
All the excuse making is unbelievable. If you're lucky enough to not notice a flaw, that is terrific.

It still doesn't exclude shoddy manufacturing though.

I took some pics of mine with "normal use" that I think demonstrates how easy it is to notice.

Does anybody even know how to contact samsung about this? Samsung UK doesn't appear to have an email address. I'm in the US and I don't have a landline so I can't really call them up.

I know Samsung US is probably going to play dumb either legitimately or just because the GS2 isn't in the USA yet so I don't really want to waste my time. Especially since when you try and email them it makes you choose the category "US Phones" in which the SGS2 is not present.
