ok, first off i wud like to apologize to someone in this thread coz i said i havnt any issues with my screen, not sure who it was but i am sorry for all its worth. second, i dont have a yellowish tint but i DO have a horizontal line about 1cm in from the left of the screen that runs from top to bottom. it doesnt seem to be dead pixels as it does change color wiv different backgrounds, what i wud say is it seems to be brighter that the rest of the screen, like this line isnt coresponding wiv the rest of the brightness settings or summot. tried loads of pixel fixers blah blah blah but nothing seems to shift it. now i read somewhere else it cud be a hardware fault? if so is there any sort of fix or is it a take it back and get it replaced job? thanks for any info and help given, and sorry for my spelling, its terrible lol

I'm waiting for a non-Frankenstein XEU...
[Galaxy S II General] EarlZ:
Looks like the AT&T version a good screen, Cant seem to see any yellow banding even on the whites/greys!
[Galaxy S II General] gtda:
I went from stock optus ke4 with very noticeable yellow tint, now I'm with kg3 & speedmod kernel and I have none.
[Galaxy S II General] BarryH_GEG:
Do you mean the overall screen, the left side banding, or both?
[Galaxy S II General] gtda:
The yellow tint on the left side, my screen still seems to have a blueish tint on the whites. And I can still see horizontal lines through the blues throughout the menus. I have also changed my color mode to dynamic
[Galaxy S II General] gtda:
I just opened up a few wallpapers I have with light grays and zoomed in as much as I could, then dragged the pic around the screen so it would vary through the other colors, about 2cm from the left it shows light black vertical lines where the yellow tint used to extend to. When dragging a light color over it u can see that there is a line there and it doesn't move when you're moving the pic, but my wallpapers are never gray so I never notice.
[Galaxy S II General] BarryH_GEG:
I know it's stupid, and I hate to ask, but have you taken pics of it? I've never been able to see the banding on mine unless I take a pic of it. If your phone passes the pic test it'll make a lot of people happy because I think everyone just assumed it was hardware.
[Galaxy S II General] gtda:
I'll try and record a video later, I'm at work atm
[Galaxy S II General] EarlZ:
Wish I had your vision and expectations :D

But all is fine with 2.3.4 kernels :D

Odd, the speedmod as of now is still based on the 2.3.3 kernel which has the yellow tinting.
[Galaxy S II General] gtda:
Speed mod is now based on 2.3.4

also now that I'm at home in the dark I can still see the yellow tint. But its very minimal, I think its just in my head that its there because I've seen it before.
[Galaxy S II General] DuoM:
Take it back and get it replaced (not repaired).

Just curious, does the line still appear in horizontal mode or any other orientation?
[Galaxy S II General] synxx:
Thanx for the reply, and i had ment to say vertical line not horizontal. But yes, in any orientation it still apears. So if the phone is vertical it runs down the left of the phone, if i hold the phone so thd menu key is on my right the line runs horizontaly along the bottom. And if the menu key is on the left it runs horizontaly along the top. Another quick question: ive flashed a custom rom, will they still replace the phone or am i better off going back to stock? Thanks.
[Galaxy S II General] EarlZ:
The reason why you can see it its because speedmod is still based on 2.3.3 but with initramfs for 2.3.4, we still need to wait for sammy to release the 2.3.4 source codes.
[Galaxy S II General] DuoM:
Thanks for that. You should return the phone to a stock ROM before returning it to ensure there are no problems.
[Galaxy S II General] xda-comet:
Hey,

I'm following the thread for a while, because I bought a S2 for myself, realized the problem, googled it an ended up with XDA-Developers once again :-D

I had 2 Galaxy S2 (about a month ago) and send them back both, because they had a very strong tinting. I decided to stick with my old Galaxy S and wait if there's a fix for the tinting or not.

Now my question is...does the actual firmware really solve the whole problem? Is the screen equally lighted out or is there still a darker area on the left side of the screen?

(I thought and read that there is not only a yellow tinting, but also that the display is darker in that area)

It would be nice if someone who tested it can confirm or reject it^^

Thank you ;-)
[Galaxy S II General] EarlZ:
The 2.3.4 Kernel alleviates the issue, yellow tint is gone but the left side is still darker than the right side but this is a lot better than having a yellow piss on the screen..

For the visually impaired try to get the lockscreen image thats used with LeoMar's ROM, its gonna be extremely noticeable at any brightness level.
[Galaxy S II General] renton82:
Sorry foto noob question, but can i use the 2.3.4 kernel on 2.3.3 rom?
[Galaxy S II General] beppez82:
Ofc yes why not!? ;)

Sent from my Cognitive Ninphetaminized SGS2
[Galaxy S II General] EarlZ:
Yes you can, there isnt much of a change from 2.3.3 to 2.3.4
[Galaxy S II General] xda-comet:
Thanks a lot ;-)
[Galaxy S II General] renton82:
Which kernel may i use for this? Or better: wich kernel sovles the yellowish tint issue?
[Galaxy S II General] beppez82:
Go with CF KG3 :)

[Galaxy S II General] renton82:
Where can i find it? Id it not necessary entire rom? With this kernel can i fix the issue?

For finding things on net I use google.com...

And you?

[Galaxy S II General] tanseerj:
I'm on KG3 and it certainly addresses this issue but it seems like Samsung has had to do some unnatural banding to compensate for this.

You can see this behaviour in the notification bar itself. Try this - pull down the notification bar and turn the phone to landscape mode, notice the bright banding on the side? Which again dissapears after a few seconds.

So it seems like Samsung has added a bright band on the left side to compensate for it.
[Galaxy S II General] renton82:
But my questione is flashing the kernel only could solve the issue or must i flash entire rom?

However before asking here i tried to search everywhere. I also think this thing is usefull for many other people!
[Galaxy S II General] EarlZ:
For those who requested, here is my screen sample with XXKG2 2.3.4

Low = 0% brightness, Mid = 50% , High = 100%

I shot it with and w/o macro mode, the 7year old camera I used also has a pink spot lol!
[Galaxy S II General] eallan:
Got my replacement device. The same issue exists.

It's a shame. I think all. Devices have this problem.
[Galaxy S II General] sachilleas:
That's unfortunate and interesting at the same time ? What can we do if we get another faulty device as a replacement ?
[Galaxy S II General] eallan:
No idea. I have a UK warranty is guess. I'll ask expansys If they will let me send it in for service in a few months. Maybe they'll sor. It out by then.
[Galaxy S II General] sachilleas:
Does samsung acknowledge the problem ?
[Galaxy S II General] dhiru1602:
The best bet would be to write to Engadget or any similar high rated Tech website to review the product and post in their blog about the Screen Issues. This would definitely catch the attention of Samsung and something could be done about it.

Don't trust the Service Center guys and don't send it for a replacement so soon. Let's wait for Sammy's word.
[Galaxy S II General] sachilleas:
I really can't bare to see this yellow tint , so i will send it back for service.
[Galaxy S II General] eallan:
Good idea.
[Galaxy S II General] sachilleas:
Maybe we should check out the replacement unit when we are at the service center (to pick it up).
[Galaxy S II General] sachilleas:
I thing that this issue is driving me crazy ...

I tried to take some screenshots (with suitable backgrounds) , so someone could notice the yellow tint.

The weird thing is that there is NO yellow tint in the screenshots!! Is there a reason for that ?

*I even showed the left yellow tint of the screen to some friends of mine so that they could verify this themselves(in case I am crazy and i don't know it:D ). They were positive that there is definitely yellow tint.
[Galaxy S II General] eallan:
Because the screenshot is all software. The yellow issue is on the hardware of the phone.
[Galaxy S II General] Leggenda:
Honestly your display looks perfect...
[Galaxy S II General] stijnr:
Well, it is slightly visible, especially in the first photo. In the status checkerboard is more visible.

I'm still in doubt whether to return my phone or not. Apparently my display isn't that bad and the chance is I'll receive a worse one in return.

Edit: I've added photos of the checkerboard
[Galaxy S II General] xclusiv8:
I must say your looks way worse than mine did.

ANyways

I have take the liberty to contact engadget about this issue and i linked to this thread. Hopefully they will write something about.
[Galaxy S II General] ranwej:
My photos:
[Galaxy S II General] stijnr:
My pink spot is also really spot on:
[Galaxy S II General] Nivekius:
That is another problem entirely and not really relevant to this thread I suppose. Though another fail for Samsung... Makes me wonder if I should even upgrade my SGS to number 2, sad.
[Galaxy S II General] r_a_c:
The worseness could be due to different camera used to make pictures, different lichtneing in the room,...

It's probably worse on some phones, but you can't judge by seeing it on the pictures.

Thanks for contacting engadget. I hope it's going to get noticed by sites like this. Because my DOA period is now over(I did not want to return a phone to get one with the same problem) it would be nice if samsung just accepted all phones with this problem and just giving them a new one...

If I return my phone now, they probably have to send it in for repair, am I right?
[Galaxy S II General] diehard2222:
hell no not getting this phone till this issue is fixed.
[Galaxy S II General] xclusiv8:
I think you are. When i returned mine they offered me to turn it in for repairs but i declined since i was still on my DOA period and just got my money back since they did not have any in stock to give me a new one.
[Galaxy S II General] NitroOnTheRocks:
Yes, I had that too + yellow left side tint + vertical line.

I could also see it after entering PIN code, the contours of the numeric keyboard stayed lightly visible on a dark / grey background (like a print, burn in).

I returned mine to the shop and I'm waiting for a replacement which should arrive in 3 days.

I hope the new device won't have these problems and will post in this thread when I have it.
[Galaxy S II General] beppez82:
And I have replied you to flash a kernel not a rom and yes as others says it is solve it depends also on your screen try and see yourself

[Galaxy S II General] renton82:
Thanks alot!
[Galaxy S II General] renton82:
Just tried but don't solve the issue for me... I've tried the speedmod kernel too, but without any improvments...
[Galaxy S II General] RjYslf:
Ok I will show you my screen . I guess you get it why I am raging here.

PS:I don't have a 50 billion dollar fortune so I can't change my phone every day Samsung screws their phones.Sorry!
[Galaxy S II General] renton82:
Sorry, but maybe cf 4.1 seems to alleviate the yellowish , but not at all...
[Galaxy S II General] EarlZ:
You have to lock the phone once then unlock it, the yellow tint goes away w/o any change in color temperature as far as i can see.
[Galaxy S II General] vaust:
I used the link the op posted for the test, no such yellow/pink or whatever on my screen, took a couple of screen shots at 0%, 20% brightness using home+power button, i'll post later if anyone is curious.

Here are the pics
[Galaxy S II General] RjYslf:
do so please
[Galaxy S II General] renton82:
Done it! Seems to work! But can i use the kg3 stock kernel too instead of chainfire's?
[Galaxy S II General] RjYslf:
epic fail.
[Galaxy S II General] EarlZ:
Yes, Can you also check KG3 if they did change the color temperature when I tested KG3 the colors seem off.. or maybe I was just imagining things.
[Galaxy S II General] vaust:
see anything weird? i am unable to notice weird colors at all.
[Galaxy S II General] RjYslf:
you still fail
[Galaxy S II General] renton82:
Wow! Yellowish tint is gone for me! Now the left side is only a little bit darker...
[Galaxy S II General] RjYslf:
good job mate kg3?
[Galaxy S II General] vaust:
updated pics. tell me do you see anything weird now? it's at 0%/ lowest brightness.
[Galaxy S II General] RjYslf:
oh jesus... yes you do have yellow tint look at the 3rd pic left side of the screen...also you didn't even post the screen with the grey notification bar... i keep my words sorry...
[Galaxy S II General] EarlZ:
Hi, Thanks for taking the time to give us samples of your screen, would you be able to take it properly this time.. even your updated shots dont really show a clear representation of anything.

What Im able to see from your pictures right now are just portions of the screen, even the test page looks entire black.

I dont doubt you when you say that you have no screen issues, I just wanna see a sample shot and what ROM/Kernel are you using 2.3.4?

Something like this that shows the phone from top to bottom, as straight as possible. Thanks ( 20% and 50% brightness should suffice )

Now tell me how good the screen now looks and feels :p
[Galaxy S II General] DrSlump76:
Hi, my phone looks exactly like yours, and i'm doubtfull that a fw update can fix this :(
[Galaxy S II General] vaust:
Here a couple more pics as requested, 20% & 50 %. I used the test page as background on these pictures.

I hope these are good enough. Forgot to add, i am not using any custom rom, just pure stock rom and 2.3.3 kernel. The nexus s I used previously owned have the yellow thing and funny weird lines when i set display to lowest brightness. Too bad i sold the nexus 4 days after i got s2, if not i'd take some pics for comparison.
[Galaxy S II General] RjYslf:
hmm have you tried KG3?

also where's it made?(99% probability that it's irrelevant but still)

also whats your kernel?
[Galaxy S II General] DrSlump76:
It doesn't seem bad.
[Galaxy S II General] vaust:
another 2 pics with the lagom page opened in browser.

same 20% / 50%

Mine's bought on the 23 July, made in China.
[Galaxy S II General] RjYslf:
slightly darker on the left side but it's one of the better screens.

kernel and country where it was made please?
[Galaxy S II General] EarlZ:
I agree, his screen looks pretty much top notch!
[Galaxy S II General] vaust:
1st pic taken was kinda slightly slanted, so kinda made the screen darker slightly on the left side. From what i can see it's very even irl. Stock kernel 2.3.3, made in China like i said in the previous post. Definitely much better than my old made in Korea nexus s, which had obvious yellow lines all over when i pull down the notification bar.
[Galaxy S II General] BarryH_GEG:
Samsung makes all their own displays. So whether the phone is assembled in Korea or China, the display's all come from the same factories.

http://www.talkandroid.com/13738-samsung-to-increase-mobile-display-production-in-2011/
[Galaxy S II General] EarlZ:
This is off topic but I cant help but post it here and laugh a bit since you also mentioned something about the manufacturing location.
[Galaxy S II General] RjYslf:
soo false.mine's made in Korea. It's trully stunning to look at the yellow tint. =))
[Galaxy S II General] BarryH_GEG:
It's great that using different kernels seems to make the screen more acceptable to some people that were having issues. But, consider this. A lot of the pics taken and comparisons made involved phones that were on the exact same ROM/kernel and they had very different color temperatures. That means the yellow is a hardware issue, not a software issue. A different kernel would effect every phone it's installed on exactly the same way. So if KGX is minimizing yellow, screens that weren't having yellow issues are going to have their yellow minimized too. So while people with warm/yellow screens may be happier those that have cool/blue screens could see something completely different. It'll be interesting to see the effect of this when the official KGX is released via Kies and more people upgrade to it. Keep in mind too that on custom ROMs/kernels the devs can be playing with the color temperature so the official ROM/kernel could have a different effect.
[Galaxy S II General] RjYslf:
any news on when is the official kernel supposed to be released via kies?
[Galaxy S II General] RjYslf:
also those with KG1/2/3 would you please mind taking A SCREENSHOT(not a photo).

I just have something in mind that bothers me. Thanks again.
[Galaxy S II General] BarryH_GEG:
Samfirmware, which isn't the most reliable source, said the beginning of August. It kind of makes sense because once they start shipping phones with updated firmware that's when they release the update on Kies. Some countries have already started shipping with 2.3.4 versions of KGX installed so I'd imagine XEU will follow soon. I'll post some before/after shots when I upgrade. Here's a couple pics of my phone on KE7/KF3.
[Galaxy S II General] RjYslf:
EarlZ would you mind taking a screenshot not a photo of you kg3 phone?

I really want to compare it to my screenshot to see if there are changed colors by any means
[Galaxy S II General] BarryH_GEG:
Here's some of mine if it helps...
[Galaxy S II General] vaust:
2.6.35.7-I9100DXKG3 kernel.
[Galaxy S II General] RjYslf:
thanks yet I wanted the notification bar screenshot

sorry for not specificating
[Galaxy S II General] EarlZ:
Since your already using XXKG3 then there should be no visible yellow tint even at 0% with all the (unrequired) special conditions.

This is actually good if they started to ship with 2.3.4 since it alleviates the issue!

EDIT: This is the first time I noticed your keyboard screen shot, if you look at it carefully your yellow tint only extends upto q, the caps key and the swipe icon.. some phones including mine extends upto e,d,x,EN keys which makes it impossible not to notice.. basically imagine a vertical line all the way down from the letter S on the samsung logo thats infront of the phone.. thats how worse some phones are.

I actually have KG2 2.3.4 installed on my phone, I didnt bother updating to KG3 yet. If its a color temperature change, I suspect it wont be visible with screen shots.
[Galaxy S II General] RjYslf:
haha mate well I understand why your screen is almost flawless. It has the KG3 kernel :D.Please take a screenshot(not photo) of notification bar and post it here.
[Galaxy S II General] RjYslf:
Anyway guys looking at those with KG kernels you gave me hope ;-( thanks
[Galaxy S II General] BarryH_GEG:
Plus some bonus shots...
[Galaxy S II General] EarlZ:
Barry, you are still with XXKF1 right? I might ask a new set of shots from you just for some added data for my research would you be able to endulge with such a request?
[Galaxy S II General] RjYslf:
You too seem to be suffering from 16-bit banding.

Now may I ask you Earl is the banding fixed in the new KG?
[Galaxy S II General] BarryH_GEG:
I think everyone on a stock ROM is.
[Galaxy S II General] BarryH_GEG:
I'm on KF3 XEU.
[Galaxy S II General] EarlZ:
Ok, this is gonna be a tall order and I would prefer if you can save it in PNG and send me the unresized files.

On the following brightness levels 0%, 30%, 50%

1.) Notification tray dropped down

2.) Keyboard screen non swipe

3.) Ring tone selection menu

4.) Dialer screen

If its not too much to ask, have the phone as straight and centered as possible.. No external lighting. A total of 12 screenshots. This may not be that scientific but Im trying to look for something else.
[Galaxy S II General] EarlZ:
The 16-bit banding affects everyone, but they say CM7 had that fixed so its a matter of developer mod. When the 2.3.4 source codes are out a lot of things might change in terms of screen display quality!
[Galaxy S II General] BarryH_GEG:
No problem. It'll be at least a couple of hours though. Galaxywings, I'm assuming you're trying to compile a couple of baseline color samples from different ROMs/kernels because one would assume screen shots are true representatives of the color(s) the phone is putting out. The only thing I wonder though is if the display drivers themselves are what's being altered which might alter what the phone thinks it's displaying in a screen shot vs. what's actually displayed on the screen. Thoughts?
[Galaxy S II General] RjYslf:
Yes that's what I'm trying to check, want to see whether the colors from different ROMs/kernels are any different. As for the 2nd statement I do believe the software updates only change the colors accordingly to the screen not to the screenshots/or the colors it should produce without the defect , and I want to see whether it looks alright on the phone screen but gradiented on the monitor with the new kernels just like with the KF ones it looks gradiented on the phone screen but on the monitor it looks fine.

My explaination sucked but I hope you can make it through it. I am going to go to sleep now as it's pretty late. Good night mate.
[Galaxy S II General] vaust:
Here are the ss.
[Galaxy S II General] RjYslf:
Hmm I see it now, and my theory failed. The same image is sent to the screen on both kernels...Pretty strange it fixed the issue without altering the colors sent to the screen.
[Galaxy S II General] EarlZ:
Thanks!. I also believe that they altered it in a low level / driver mode change thats why screen shots cant capture it.
[Galaxy S II General] renton82:
Is there any good kernels based on kg3 that can i try instead of chainfire and stock kg3? I've tried speedmod t16 but the yellow comes out again :(
[Galaxy S II General] mach0boi:
None as of now as sources aren't out yet.
[Galaxy S II General] EarlZ:
Since the source code for 2.3.4 isnt out yet, all the "XXKG1/2/3" kernels you see are just 2.3.3 So they will all have yellow tinting aside from CF since its a 2.3.4 kernel with rooting just injected.
[Galaxy S II General] renton82:
Ok, i'm waiting then...:(
[Galaxy S II General] archion:
Yes, same problem here, I've tried most kernels, no difference. The only way to really fix this problem is to change display..
[Galaxy S II General] renton82:
Or kg3 kernel...
[Galaxy S II General] mach0boi:
Kg1, kg2 and kg3. All 2.3.4 kernels lessens the yellow tinting.
[Galaxy S II General] archion:
Erm, I tried Speedmod t16 (newest is kg3 kernel).

The yellow tinting might get a little darker, but it makes it even more visible.
[Galaxy S II General] mach0boi:
It is not based on KG1, KG2, or KG3. Still based on 2.3.3 maybe KFx versions of kernels
[Galaxy S II General] archion:
I am running lite'ning rom currently, that one is 2.3.4 with KG3 kernel.

No real improvement from the stock 2.3.3 rom.

and to add:
[Galaxy S II General] themissionimpossible:
Curiously also a supposed new GS2 version shows similar display problems (see the reversed stripe)::(
[Galaxy S II General] Mikulec:
Making this test on that picture is nonsense.
[Galaxy S II General] deanwray:
LOL, sorry but do you know for sure the image has the same colour and luminance value across that strip ? ;)
[Galaxy S II General] themissionimpossible:
I'm sure that the display should have the same values horizontally (and vertically)...;)

And that display is obviously overall darker on the left (see also the blue area), like the GS2's generally is.:D

The following pic is a reverse test of a very small uniform area (which isn't clearly an image;)) and the difference (left-right gradient) is already pretty evident!
[Galaxy S II General] EarlZ:
Its darker to the left coz the screen suffers from the defect, which 99.998% of the people are blind about
