I'll try to post a better image in a few hours. I'll put my camera on a fixed setting to get a sharp image.
[Galaxy S II General] Bratag:
Let me see what I can do. You want a dark room/notifications tray pulled down/low brightness and a high brightness correct?
[Galaxy S II General] jonny_ftm:
Great engadget posted it.

I sent them a long email with the 3 main ways to spot it + link to thi spage

Sent it to reviewers chief + the reviewer of SGS 2

Now, RMA will be easier to do
[Galaxy S II General] TML1504:
i also do NOT have this issue, but a friend of mine has/had it. he sent his g2 to samsung back this week! he had the device for about 2 weeks, and i'm almost sure he didn't had this issue from the beginning (because of me having dead pixels i checked his g2 when he got it, can't remember that it was THIS yellow as it had been when i last saw it)!

i agree with your thought on the heat related issue as well, was one of the first thins i thought when i fist heard of this problem!

so now, question @all having this problem:

have you done something which made your device hot for a longer period? for example gaming? or was this issue straight from the beginning?
[Galaxy S II General] eallan:
That would be great. Head on pictures.
[Galaxy S II General] TheQuarterMile:
Guess there is some issue or the other with SAMOLED screens. Still waiting to get a perfect screen... :(
[Galaxy S II General] Ogy77:
Hey guys whats up?I have sgs2 and is great,just one problem no yellow tint,but when I in dark room and screen on but black I see some spot,what is that?
[Galaxy S II General] EarlZ:
Spots that are brighter?

Its a manufacturing defect, it should be in a uniform but very faint glow.
[Galaxy S II General] Ogy77:
Is that serious problem?Everything work and displey its normal,I just see spot:D
[Galaxy S II General] bazzag:
If you like staring at a black image in a dark room all day then yes, it's quite serious.
[Galaxy S II General] EarlZ:
If you have to ask that question then its not a serious problem on your end.
[Galaxy S II General] Ogy77:
Thank you guys for answer,this no see and not problem:D.
[Galaxy S II General] fourthree:
just updated my sgs2 firmware to XWKJ1 thru kies and i think the yellow tint has disappeared:)
[Galaxy S II General] Foscot:
Same "problem" in a dark room with black picture

I have the same kind of problem as you. In a dark room, displaying black there are some black "spots" on the screen there are darker than other areas. It's no real problem for me, but if it's something serious (affecting lifetime etc.), I might contact Samsung about it.
[Galaxy S II General] -Nane-:
In my black SGS2 I havent had any problem with yellow tint but 4 days ago my friend received his new SGSII white and he has problems whit the yellow tint color in the screen... How can happen that?
[Galaxy S II General] Ogy77:
I ask everybody and say this is not problem serious,just LED flash up,so enjoy in you perfect S2;).

Maybe flashing new rom can fix spot on black screen in dark room,now I am on CM7 nigthly?!
[Galaxy S II General] EarlZ:
It mostly affects people who read ebooks in invert mode, watch movies with lots of dark scenes in a dark room ( usually before going to sleep ) some use the S2 as a night clock.. difference in usage.
[Galaxy S II General] Ogy77:
So this is not serious problem,right?Maybe flash new rom and fix this what you think EarlZ?
[Galaxy S II General] EarlZ:
Like i said it all depends on usage, for me it was extremely serious.
[Galaxy S II General] gr4ndm4st3r_bl4ck:
The black bleeding marks seem to be something totally normal and affecting the majority of the phones

( those who claim they don't have it , probably don't know what they're looking for ). On the other side the yellow tint thingy seems to be a software problem.

I got my phone a month ago , it was on stock 2.3.4 and it was noticeable ( when i looked for it hard enough ).

A few days back i flashed 2.3.6 XWKK5 and I couldn't notice it no matter how hard i tried. Then I flashed CyanogenMod7 and it came back, more yellow then ever.

A real pain in the a$$. Now I'm on CheckROM RevoHD and again , there is no trace of the yellowish tint. Makes me wonder what this is about.
[Galaxy S II General] EarlZ:
My first 2 S2's didnt have the issue, the 3rd one had it really bad the 4th on that was a store replacement also had it.. didnt bother checking the 5-7th replacement.

If its a SW issue then the yellow tint should come up with screen shots, the severity per phone really varries altho I've started to see more and more units NOT affected from friends who recently got their phones. 4-5 months after initial release should be enough to iron out production flaws.
[Galaxy S II General] gr4ndm4st3r_bl4ck:
I lol'd at this. You, my friend, have no idea what screenshots do.

When you do a screenshot on the phone , the screenshot itself doesn't show you exactly what YOU see on a screen

( eg. how the image rendered appears to you ) , it rather shows you a frame of what the system looks like at that particular moment.

The kernel, ROM, or anything else could render it badly ( because sAmoled+ screen tech is not yet perfect ) ,

and it appears yellowish to you, but for the system itself its perfectly fine... So , the kernel or ROM says : render grey , you take

a screenshot , its perfectly grey when you check it on pc , its still yellowish when viewed on a phone. When i say hardware issue i mean scratches or marks on the display unit itself, and

when i say software issue it may mean anything ranging from gpu rendering, kernel , ROM, or even an application itself.

So no, you'll never see it on a screenshot if it's concerning the rendering, whether its a software or a hardware issue.

Oh yes, my SGS2 is only 1month+ old , so its a newer version alright , still have the issues.
[Galaxy S II General] EarlZ:
You didnt get it but thanks for trying, sucks though that your accepting a defective phone when the newer batches are already fixed.
[Galaxy S II General] Prankey:
EarlZ thanks for looking at this issue. Do you really believe that the newer lot has fixed this issue?
[Galaxy S II General] EarlZ:
Probably not all but I believe the newer batches either have better quality control or improved manufacturing of the screen, It maybe just be pure coincidence but I've seen a lot of already great screens from retail stores and even the demo units were changed with newer batch as per the store reps that I've had contact with before when I had my S2 ( made a lot of store rep friends during that time )
[Galaxy S II General] TechNoir:
I just skimmed through the last pages. I bought my SGS2 in May and the yellow tint (if that is what you are discussing) is, if not 100% software-related, then atleast 100% managable in software.

Also "gr4ndm4st3r_bl4ck" (thank you copy/paste ;) ) is correct, saying something related to SW should be captured in a screenshot is not always correct. SW also manages screen calibration and other things. I could theoretically tell the driver to render the screen with only red pixels, whilst a screenshot at that point will shot a normal, full color image.

My phone, depending on whether I use an older SW (without kernel fixes from Samsung) or a newer one, will change from a tinted display to a perfectly uniform color temperature from left to right side. I'm not saying some phones might deviate from the norm and being more tinted than others with same FW.

Just wanted to add that.
[Galaxy S II General] gr4ndm4st3r_bl4ck:
So someone did actually understand what I was talking about.
[Galaxy S II General] cioly:
@EarlZ I had same problem with S2, had a lot of fights with orange and contacted samsung for help in solving my problem and after I sent the phone 5 times to warranty, they replaced finally with a brand new one. I had no courage to open the box again so I kept it sealed to sell it. I was tired with Samsung's faulty phones and switched to Apple. I was a Galaxy fan. I hated Apple in the past but now I love it, no more problems. I used SGS1 and flashed hundreds times and I know Android a little bit so all I can say is that every thing that Android and iOS have in common, Apple made it better on iOS (notification center is an example that they copied and made it better), but I miss widgets from Android and the customization of home screens.
[Galaxy S II General] EarlZ:
I can understand your frustration about it, actually Im just waiting for a better/bigger screen technology from another competitor and I might switch to them.
[Galaxy S II General] bazzag:
Good luck waiting, Samsung nearly monopolize all AMOLED production in the world, which is the reason they can get away with tinted/grainy/blotchy/burnable displays on $500+ phones.
[Galaxy S II General] EarlZ:
If it wasnt so obvious, IPS displays.

I personally believe that its not samsung alone to blame but more on the end user for accepting such defects but hey dont let my expectation be theirs on a $500 phone.
[Galaxy S II General] Crox:
My SGS2 I bought last week has a yellowish left side too. Firmware: 2.3.4.

Funnily after a while the yellow left margin disapears after a while.

Each time I reboot the SGS2, the yellow margin is back. Is this a problem with software/firmware or a defective hardware?

Why does the yellow margin appears after rebooting ...??
[Galaxy S II General] Erethnor:
You need to lock/unlock the screen with power button to make it disappear, once after every reboot
[Galaxy S II General] Crox:
Same to me! 2.3.4 KI4 - the yellowish left side came back after reboot and disappears after unlocking screen.

Is there no solution to make the yellow left side disappear forever?

---------- Post added at 09:24 PM ---------- Previous post was at 09:22 PM ----------

Thanks. That's what I find out too - why does the software can't solve this too: no yellowish left side after rebooting.
[Galaxy S II General] EarlZ:
The software alleviates it probably by a color temp change, we will know once the source codes are out.. or are they already out ?
[Galaxy S II General] Headbanger1982:
Hi guys, I bought a brand new Black SGS2 the 24th of december and realized that it has the same yellow issue on the left lide and apparently two little darker colums on the right side, sice i work in the ship where I bought it I just made a comparison with the ones exposed that I have in the shop, mine vs another Black one and a White one.

All three devices have the same yellowish tint issue but on mine was a little bit less noticeable, instead the exposed Black and the White didn't had the darker columns issue.

And I've noticed that the White one, with same brightness level set, is really blueish versus mine or the other Black exposed phone...

This yellow thing bothers me since I use the phone with autobrightness ans often it sets to low darkness so I can see it quite often, even with software upgrades (KI4 2.3.4) it doesn't solves... so I'm starting to really thinking about changing it with a brand new Sensation (never made a single phone call since, so I still can do it)

I've read many pages of this thread but I've noticed that not all of you solved the issue, so do you really believe that it is a problem that can be fixed with time?

Otherwise I really think that I will switch to HTC this time...
[Galaxy S II General] gr4ndm4st3r_bl4ck:
Nope , it will never get fixed. with some experimenting with roms and kernels you can make it almost unnoticable. As for auto-brightness - it sucks... lags and drains your battery like hell ( sensor consta-working ) . Just set the phone to around 40% brightness ( you cant notice the yellow tint on 40%, at least i cant).

Oh yes, one more thing. Sensation suxx badly.
[Galaxy S II General] Crox:
I thought, the yellowish left side bug was canceled with FW 2.3.4? I didn't sent my SGS2 back to the dealer because I only see the yellowish left side after a reboot. When I switch the SGS2 of and then on, the yellow left side has gone.

Now I'm doubtful if newer Firmware-updates will fix this bug too?

Is this a credit of Samsung? Will newer Firmware-updates also fix the yellow left margin? Some devices get the 2.3.6 - is there the bug still fixed?
[Galaxy S II General] Visentinel:
I got my gs2 on Tuesday 27th in Australia NSW.

Perfectly uniform color over the whole screen. Guess I'm just lucky. :D

sent from I9100 using Omega
[Galaxy S II General] EarlZ:
Not that it matters to me anymore but Id be interested if you downgraded the firmware and see if its uniform or just the color temp change compensation going on.
[Galaxy S II General] gr4ndm4st3r_bl4ck:
Lower the brightness to 10% and then check it ? Also being in a dark room helps noticing it...
[Galaxy S II General] custode:
mmmm... I don't know what to do.

I bought a galaxy s2 in may and sold it after a month due to the yelowish left side problem... now I was thinking to buy it again, a new one, white color.... but I see that this problem is still here!!!

That is a shameeee, this is the best selLing phone worldwide, and it has this problem on almost every device?!?!

That is nonsense.

Well, I'll see what to do.... If you have advices, are appreciated... mostly important, is there any difference, concering the screem, between the black one and the white one???

Thanks!!!
[Galaxy S II General] nomnompie:
I myself have noticed something odd..

Probably 98% of the time I don't notice the yellow anymore since upgrading the firmware however lately I have noticed that when the phone heats up, there is an area maybe the size of a nickel that gets fairly yellowish again at the top left of the screen. Oddly though it seems to go away when the phone cools off..
[Galaxy S II General] EarlZ:
Sounds logical as thats also the central heat (area) made by the CPU.
[Galaxy S II General] jonny_ftm:
Just got a 2nd i9100, for my wife. It also has the same little tint as mine bought 6 months ago. Know what, I never cared about it. It's an amazing phone but just like you can't expect it to outperform even a point and shoot camera, don't expect it to have a graphist pro screen.

Really, you have to look at it on purpose to spot the artifact. If your unit is really affected in normal use (which I never saw despite inspecting so many phones at my friends and showrooms) ask for an exchange. Just keep in mind that this "defect" is on all devices. Some people just don't know how to look for it and others just don't notice it: we don't have same ears, neither same eyes :-)

Hopefully, my eyes, my wife's eyes and my friend's eyes never noticed it on daily use unless I look on purpose in the dark, at low brightness and at a grey background: what a nice scenario to spot it...

If it desturbs you so much, either you have a really bad unit (that you should exchange) or you're a little on the obsessional border...
[Galaxy S II General] DrSlump76:
If you noticed and it does not disturb you, it means you're ok with a defective product. This behaviour autorizes Samsung to produce their product with a low quality profile, as used with the sgs2 (low quality hardware, low quality chassis, low quality display). It shines if you look at it from 3m, but the shining disappears if you give a better look to it. This could be accetable for a low budget product, but not for an high end one, like sgs2 is.
[Galaxy S II General] EarlZ:
Very true, this is the main reason why quality control is extremely low even on the new phones like the galaxy note and nexus, pretty much this will extend into the s3 line.
[Galaxy S II General] podface:
my screen is slightly bluey green which is supposed to be normal but the yellow tint is not supposed to be there. You got a defect. return it :)
[Galaxy S II General] mikk_:
I got this same problem with stock KI8 firmware (2.3.5). When I flashed cyanogenmod 7 I haven't had this problem since. Could this be software related? Like how stock roms handle display on low brightness...
[Galaxy S II General] EarlZ:
This should have been alleviated with KI8 already since its using 2.3.5, as long as you dont see it anymore with the new ROM then its all good.
[Galaxy S II General] goofy3:
Hi,

I've just got SGS2. Stock rom was KE9 (not sure) and I don't notice nothing wrong with screen. But after few minutes I flash it with sensation v2 and after setting everything up I saw yellow tint on left side... So I tried diffrent rom http://xdaforums.com/showthread.php?t=1482372 and it is still there :( Do you recomend any kernel to ICS which remove this tint? Or maybe some good other rom without ths issue? Phone is brand new so I can return it, but from this topis I see that is pointless..
[Galaxy S II General] EarlZ:
As long as you use a 2.3.5 based kernel ( built from source ) the yellow tint should not be noticeable anymore. I have no idea what kernel that ROM uses though.
[Galaxy S II General] goofy3:
Thanks, could you post some kernel names for ginger or ICS? I check few kernels and all are fully custom, and I don't have idea which will be ok... Thanks in advanced!
[Galaxy S II General] EarlZ:
All kernels from CF with root are surely built up from 2.3.5 sources.
[Galaxy S II General] eric325:
I'm using rooted DXKL3 build. I have installed 'Voodoo Screen Tuning R&D dev snapshot 49', native mode, gamma set to M2 and screen mode set to Dynamic. I have noticeable full white screen now :D
[Galaxy S II General] azulgranas:
Samsung advertised their display is superb but after buying this phone only its screen made me very disappointed. I think maybe i'll never buy any samsung smartphone from now on. I used to hate apple product but now i think apple is a brand that produce perfect products with a clear conscience, in the other hand samsung does not cause they knew this issues but they still sold this phone.

---------- Post added at 07:51 PM ---------- Previous post was at 07:45 PM ----------

Why did you do these things to fix this problem yourself. That's samsung's work. But they didn't work, never work. i think it's not worth buying this "high-end" phone.
[Galaxy S II General] WaPeR32:
I solved it flashing the LPB ICS ROM
[Galaxy S II General] EarlZ:
The Tab7.7 which also uses the SuperAMOLED Plus screen has similar issues, uneven brightness from left to right or top to bottom and crappy grey renderings.

EDIT:

Though Im wondering if the Galaxy S2's with a build date of Dec2011 onwards still stuffer from the visible suction cup rings?
[Galaxy S II General] Primenay:
The most recent firmware DOES NOT fix the problem. Or tell me which one your using because I am fully updated and it still is apparent all the issues with the screen
[Galaxy S II General] jj_95nano:
AMOLED is the best display in my dreams...

Not only do I have yellow tint on the left side, my overall screen color temperature is yellow. I have stock firmware. If I leave the problem like this itself is it gonna cause any long-term consequences? I plan to use this phone for at least 3-4 years...(I'm 16 and my parents won't let me buy another till I'm 20.)

Pic 1: See the yellow tint on the left.

Pic 2: See how my GS2's display is soo yellow when compared to my desktop monitor.

Didn't expect this from Samsung. I have an April 2012 mfg. model.

PS: Sorry for the bad quality pics... took them from a webcam :P

EDIT: I also have black blobs and smudges on a black screen when I see it in pitch dark. Also on lowest brightness everything seems to have linen like texture. Grays are rendered greenish. I have 2 burn-in lines; and

it isn't even 3 weeks old!
[Galaxy S II General] Lulabby:
Which version of stock rom do you have? This problem is solved when you update to newer roms such as stock ice cream sandwich 4.0.4. So you should connect your phone to Kies and let it update to the newest rom. Hope it helps.
[Galaxy S II General] jj_95nano:
I'm on latest 4.0.3 for my country. I have even rried custom Roms and kernels; they don't remove the tint, they just try to hide it... I'm beginning to have second thoughts on keeping this phone. :-/
[Galaxy S II General] xdadarun:
Hey i too had the same issue a year back. Also i changed my mobile wit samsung and got a new one. But again in a few months i got the prob in my new mobile. Then i left it as such as it dint bother me on automatic brightness. Now after seeing u thread i chked this again im my mobile amazing i cudnt find it even in lowest brightness. The yellow tint not thr:). All i did was upgraded to ics 4.0.4 stock official. Hope this helps. Upgrade and run it for few months. All the best.
[Galaxy S II General] *boy*racer*:
I haven't got the yellow tint, but I do have the black smudges and blobs when screen is in a dark state with real low back light. Maybe it's dust? Pfft I have no :o

Yellow screen

I bought 2 SGSII two days ago and - one (white) has a perfect screen and the second one (black) has the screen all yellow. When I set the screen brightness to low values it is really really yellow - there is no white all yellow. Both phones have exactly the same software version - 4.0.4. Any advise? I guess the black one has to be shipped to Samsung?
[Galaxy S II General] jj_95nano:
I have an s2 that has a yellow screen like that. It's never gonna get any better. I can live with it but i don't know about you. If you can't, then get it replaced NOW.

[Galaxy S II General] olszan:
Thanks! I will call Samsung official service tomorrow and will post the reply here so stay tuned if you're interested...
[Galaxy S II General] jj_95nano:
I'd like to know how it goes... :)

Sent from my Bathtub using bubbles
[Galaxy S II General] olszan:
OK. I called Samsung official service and described the issue (yellowish screen at low brightness) and they told me to bring it to them for diagnosis and most likely for screen replacement. I asked, out of curiosity, if it could be software issue - they said it is unlikely and is probably caused by faulty display.

I'm just very disappointed as it is second SGSII in a row with screen issue. First device I had in my hand when signing new contract had dark spots in the very middle of the screen. When I noticed that the carrier replaced it immediately with new device. And now this yellowish crap. I would expect a bit more quality from such device...
[Galaxy S II General] jj_95nano:
We definitely want a perfect screen because it is Samsung's responsibility to ensure that their screens are quality tested. We shouldn't have to keep going backband asking for replacements. I'm not a supporter of Apple; but they never let such things happen. Samsung advertises the SuperAMOLED as crisp, colorful, blah blah- but turns out to have a lot of defects. My s2's screen has an overall yellow color temperature and yellow tint on the left. It has black spots in low light. It has burn in marks. It also has lines on grey backgrounds in low brightness. Also, if you're able to notice... On a white background at lowest brightness most s2s have yellow tint on both sides and pink tint in the middle. Sheesh!

I could have got a replacement, but I can manage for now... I'll get one when I probably smash the screen :p

Last AMOLED phone

Sent from my Bathtub using bubbles
[Galaxy S II General] olszan:
But this seams not to be the case for all AMOLED screens. I also have second SGSII and the screen is perfect. And I have SGS (first edition) and the screen doesn't have any defects. Apparently this issues are common to SGSII phones - perhaps Samsung ordered poor quality screens to lower the overall phone cost...
[Galaxy S II General] jj_95nano:
Yeah, you never know. But checking quality is Samsung's responsibility not ours... In your case you're lucky, so enjoy;)
[Galaxy S II General] bartoloandre98:
U described my phone exactly, issue by issue, the yellow tint, lines, dirty grey backgrounds, half yellow half not, pink tint in the middle
