lolz amiditly the sensation screen isent as good as galaxy s2 but i have never seen a sensation screen that yellow lolz another thing that bugs me about the s2 screen thou is the ghosting / blurring text when browsing.

Fingers crossed next samsung phone better but i doubt it , will see friday thou when replacement arrives.

But this along with purple spot on camera is just laughable and typical of samsungs build quality across the board,I dont know why people would accept these issues when the phone costs as much it does network free , just crazy.
[Galaxy S II General] sriharsha_m:
No, I really haven't spent enough time on looking for firmware's and custom ROM's yet, It's just that this yellow patch issue is too significant for me to ignore. I have heard about some counter was implemented in S2 for couting ROM changes, haven't read about it, but I want to root my phone first so that I can move my titanium pro backup from Desire to S2, Where should I start first??

I have an iPhone 4 too, never faced any issue with it apart from a non working earpiece for which I got a new phone as replacement. Apart from that no issue ever, it's just that after spending so much on S2 it was in transit most of the time due to the replacement procedures and that's irritating.

Yeah, Same issue here, but 2-3 of my friends who bought their S2's almost 2 months back have perfect screens, which are of Korea make, while mine and the other S2's with yellow spot issues are of China Make as far as I observed.

I can guarantee that their screens are perfect as I checked all those S2's side by side, will take a pic next time we meet again and upload here.

Oops, Can't seem to delete my post (didn't realize I was looking at the wrong page when replying to an old post. Can't delete from XDA app either. :(
[Galaxy S II General] Devhux:
I've been skeptical that I could get rid of the yellow tint via software, but looks like Cognition ROM has done something to hide it. Even at minimum brightness I'm no longer seeing yellowing on the left side.
[Galaxy S II General] Lulabby:
Glad that we have a solution to it. And yes, all new kernels can get rid of the left side yellow tint.
[Galaxy S II General] gbohm:
well are you sure? i think the source for the fix wasn't released yet so a build kernel will not have it (cf-root fro example should have the fix)
[Galaxy S II General] azreil24:
After updating through Kies to KH1, Orange Romania version, upd from KG2, the screen is now almost perfect, no more yellowish left side. I rootted the phone whit cf-root, with the same KH1, and the screen is the same, no more yellowish.
[Galaxy S II General] Wiggy Fuzz:
the side of my screen got a yellowish tint while i was reading my emails. it's only there when the screen brightness is low - at high brightness it's not noticeable at all.
[Galaxy S II General] thanostc:
Have you noticed that if you put the phone in test mode with the code *#*#0 bla bla the yellow tint is not there.. It' very visible if you enter gmail for example... What about that?:confused:
[Galaxy S II General] matee89:
Hello everyone!

Today I did an update through Kies (Android version 2.3.4, new baseband etc.) and the yellow tint issue is gone. The screen is just perfect now to be honest, haven't see any issues with it. May do the trick for all devices. Cheers!
[Galaxy S II General] Qu@rk:
I have done some testing during the last 4 weeks.

I had 4 Galaxy S2 and every one has the yellowish tint problem on the left side of the display. Some had a more or less camera problem (red dot, sharpness) some had issues with GPS and two a very strange display (totally dark). My current S2 is not perfect and the display has also the yellowish tint problem, but it is the best out of 4.

I was so suprised when I flashed the XXKH3 coming from KE7. After reboot I had to activate the lockscreen one time and the yellowish tint was completely gone. After the next reboot the yellowish tint was there again but after lockscreen activiation/deactivation the tint was fixed (as already reported in this thread).

So, I testet some different ROMs to see, which one I like:

Litening ROM 6.1 XXKH3: NO tint fix

Galnet MIUI base MIUI 1.9.9 and 1.9.16: tint FIXED

Leomar Revolution ROM 2.6 XXKH3: tint FIXED

CM7 (last week): NO tint fix

Tint FIXED means, you have to activate the lockscreen at least one time to see the fix.

Someone reported, that CM7 would fix the tint problem also, but the tint problem stayed with the CM7 build I tested last week.

BTW, I will stay with Leomar Revolution ROM. CM7 is great, but too experimental and Galnet MIUI is very, very nice, but also too experimental (I had some problems with their own framework, problems in menus etc.) and unfortunately, as well known, both no BT audio support, which is needed for handsfree sets.

It would be great if CM7 could provide this tint fix for the S2 also.

From what I have read CM7 has it's own color engine (and there are fixed color profiles in the UI, but none of them is usable, because of wide spread for standard factory models). But it would be possible to calibrate the display perfectly if the CM7 UI would provide the needed settings (RGB values for gain/bias or multi-point calibration, gamma calibration, even sharpness/DNR etc.).

Supercurio is working very hard on a color management solution for the S2.

Maybe he is able to do this not only for stock based ROMs but also for CM7 based ROMs (called ASOP I think? correct? :) ).

Best regards

Qu@rk
[Galaxy S II General] thanostc:
@ Qu@rk

By the "tint fix" do you mean also that the left side of the screen which was more darker has been fixed?

Best regαrds,
[Galaxy S II General] Qu@rk:
I am sorry, I am not able to say anything about that unconformity problem.

I never had a S2 wich a significant darker left side (or I did not notice). All my S2 had a significant yellowish tint on the left third of the display.

But try it! It is so easy to flash a new stock ROM release via odin. There are so good tutorials here and if you do it slowly, step by step, it is so easy. I would recommend to flash KH3 (3-part with pit file, a bit more complex to flash but nice and clean) or the brandnew KI4. I still have KH3.

The only thing is, with the 3-part version (incl. PIT-file) you have to configure the system completely new. But with backups of contacts in your google account and apps in the market it is easy to restore. Only for specific backups (Titanium Backup) you would need root. But even root is a pease of cake and has many advantages and very easy to restore to factory state. Just try! :)

Edit:

If you come from KE- or KF- stock ROM releases, I would recommend to flash the 3-part version KH3 first, because of a complete repartition/system reset (full wipe). Your internal (and external) SD card will be untouched unless you do a factory reset with formatting the sd card.

But it is only complex to read but very easy to do and it is worth to try!
[Galaxy S II General] Declan79:
What a great news also I hust got info from samsung centre it might help woth setting red color little bit dominant from the blue to reducing the yellow tint?

send from my premium XDA GT-P1000 2.3.3|DXJPE
[Galaxy S II General] azreil24:
I've noticed that the yellowish side did not completely dissapear, is visible when the phone gets hotter and the screen light is very low. When the phone cools down there is no more yellowish. ROM BVKH1 with Ninphetamine 2.1.3 kernel.
[Galaxy S II General] Qu@rk:
This would be right, but how should you do this?

There is no separate setting for red color etc.

Edit:

Yellow is to much red and green so you would need more blue.

But, as said, there is no setting in stock ROM for RGB values.

CM7 would be able to offer this in the UI because CM7 has it's own color engine but the CM team would have to implement a color management with appropriate settings. But without the "tint fix" for the S2, CM7 is not very attractive. I have tested it yesterday again with CM7 Nightly 60 and my yellowish tint on left 1/3 was there again.
[Galaxy S II General] Chad_Petree:
my galaxy s II also has that yellow stain on the left side :( , wasnt the iPhone 4 supposed to have the same problem? and that it went away within a month or tow?
[Galaxy S II General] Lulabby:
You can use Screen Adjuster on Market to adjust colors.

Cheers
[Galaxy S II General] Qu@rk:
Will not help with these display problems (yellowish left side, darker left side).

The app does not change anything in the driver or display.

Very useless app.

Supercurio (Voodoo control for SGS1) works on a solution for SGS2. But it is very complex to reverse-engineer the Samsung drivers, hardware registers and settings.

Regards
[Galaxy S II General] Lulabby:
If you want to minimize the yellowish left side, use the new kernel from Samsung stock firmwares, such as from KH1 forward, or use the one of CF if you want root. After that, use Screen Adjuster to make white color becomes whiter by increasing blue. The program does not make the yellowish left side disappears, use have to use the new kernel first.

Cheers.

yellow tint gone

I got my S2 about a month ago. I soon noticed that whites looked dirty even when brightness was at 100% and grey loading screens had a very yellow tint on the left of the screen. It turns out I had a fault screen and got an exchange. I rooted my new phone and installed modaco GR5, whites looked fine but grey screens still had the yellow tint. I tried a few new kernels, no change so I tried some different roms and settled on ☜☆☞ Check's DK Gold Edition V3.5 FINAL ★XXKH3★ ☜☆☞ no yellow tint even with auto-brightness on.

I suspect that Hellcat's Root Kernel which came with the rom is the reason the yellow tint has gone. :D
[Galaxy S II General] anshmiester78900:
Same story here bro :D
[Galaxy S II General] Warren.D:
My other half has got a brand new white S2 yesterday and its yellow side is worse than mine also the pink spot is more prominent. Btw my hanset was from one of the first batches.
[Galaxy S II General] EarlZ:
Samsung keeps letting this defect slip by since a few people dont return and complain about it to the service center :(
[Galaxy S II General] maseltov:
Im totally new to this board, so sorry for my question, but is there a tutorial for these steps? I also have a Samsung Galaxy S2 with a "blue white" and a yellow tint and its pretty annoying.
[Galaxy S II General] SAlmighty:
i think every s2 has this yellow issue. some may be very prominent some may be very faint. mine has yellow on bottom left corner but there is some better uniformity on the screen compared to other s2's i have seen. therefore, i can't really complain. if i get this one replaced with another s2, it may as well be worse.

i am confident this is more of a software problem than hardware.
[Galaxy S II General] gbohm:
yeah search for it if we just would give you the steps you wouldn't need to read more which is important so you don't brick your phone
[Galaxy S II General] madman_cro:
flashing 2.3.5. stock solwed my tint probs
[Galaxy S II General] nigel83:
do you have the dark/yellow left side too or what?

Can someone post some pics showing "before and after" if new kernel solves this left side problem?
[Galaxy S II General] EarlZ:
The new kernel lessens the issue on most phones resulting in a darker left side.. its not totally solved.
[Galaxy S II General] liquid045:
i also have this problem, just 3 days since i got it. very disapointing and its supposed to be the best in the world sigh. i kick myself for not going with nokia like i always have
[Galaxy S II General] gbohm:
jap give it back and get a nokia

or flash kh3 and be happy again
[Galaxy S II General] zankuru:
Hi,

got my sgs2 3 days ago...

at first i don't see the yellowish tint on the left side but now as i follow the instructions (found in the first page of this thread) to the page: fiddle.jshell.net/qFxsC/1/show/

I realized that in about 20% brightness, i can notice a very slight yellowish tint of around 1/16 of an inch on top and on the left. Its not very noticeable, but on 100% brightness i can see that the yellowish tint is very visible and is on my whole screen. not only on the left side... it seems rather uniform for the whole screen when on 100% brightness tho.

im running the stock kernel version: 2.6.35.7-i9100XWKF1-CL265340 root@DELL106 #2

Baseband version: i9100XKF1

is this a considered a new kernel where the yellowish tint has slightly been addressed or does this belong to the old one which has not been addressed with?

thanks
[Galaxy S II General] Lulabby:
Hi zankuru,

Your kernel is old, try the new one such as KH1 onward to lessen it. And let us know if it would help you.

Cheers.
[Galaxy S II General] SAlmighty:
I went through 3 replacements and the 2nd to last one had a better overall display. However, a thick vertical line appeared which led me to believe that the screen was defective. I got an immediate replacement the next day and to my surprise, the yellow is more prominent on this 3rd device. there are 2 areas of interest, one on the lower left which resembles a right triangle and one on the top right like a small rectangle. At maximum brightness the yellow is almost invisible, but go to 20% brightness and the nightmare starts. The phone is running perfectly; I don't seem to have banding issues like others have mentioned on the forum. Banding appears and seamlessly disappears when rotating screen. i would say this is normal and a flaw in the amoled plus technology. heating is not an issue. there is no backlight bleed on the buttons, and the phone is made in korea with the battery made in japan, finished in korea. I don't know if the yellow is something to worry too much about. the first 2 phones did have yellow, though less visible. it may have to do with software. let me know what u all think.
[Galaxy S II General] SAlmighty:
so, are there any roms that will alleviate the yellow tint issue?
[Galaxy S II General] MiloFoxburr:
I went from a very noticeable yellow tint on KE7 @ 0% Brightness to No tint at all in KI3.

The only time I can see a problem with the left hand side of the screen is if I set brightness to 0, turn on a 40% screen filter (To make screen even darker) and turn on Night Mode from ChainFire (To turn the whole screen amber). Even then it only looks a slight be darker and I might just be imagining it.

So yeah for me who did notice the tint issue it's gone in KI3.
[Galaxy S II General] Lownita:
Tint is gone for me since kg1. Ninphetamine kernel is the only custom kernel that inherits this feature as far as I could say.
[Galaxy S II General] prinzhernan:
I noticed that the issue disappears in my phone with KI3 however just recently I noticed a faint line on the lower left side of the screen, a vertical one rising halfway through the screen. Though this is only noticeable at 10% brightness or lower and on the notification drawer and the clock screen only.

Worried by this I went to the main Samsung service center and while acknowledging the issue they admitted that this is the flaw of amoled plus technology because of the way it's made. The technician explain that it is printed like paper and there are multiple layers. He also showed me two other units with a line on the left side too but in a different location than mine. To cut the long story short they wouldn't replace it since to them this is normal. Oh well.

Really happy with the phone and screen though but it's sad that the manufacturing process has not been perfected.
[Galaxy S II General] SAlmighty:
interesting thing to note, the yellow on my screen is kinda bearable. i say this because the screen is more uniform unlike the previous devices I went through where a vertical and horizontal lines would faintly appear 1/3 from the bottom of the screen and half screen would be darker than the other.

if this yellow tint is resolvable through firmware update, then I'm fine with what i currently having. i don't want anything worse.

does anyone think that an official update from samsung will fix this issue?
[Galaxy S II General] matee89:
Yes! I've already wrote it here before. Official update through Kies fix the yellow tint issue. Note that it must be android version 2.3.4 update (XXK1) so if it's not out yet for your country - you must be patient then.
[Galaxy S II General] SAlmighty:
Okay, I've gone through more than 3 S2's and wanted to know why are all of them having the yellow tint issue but NOT TO THE SAME EXTENT. ISN'T IT THE SAME FIRMWARE LOADED ON ALL S2's. I'm confused. someone, please explain. thank you

:confused:
[Galaxy S II General] EarlZ:
Because its a manufacturing defect, its not "normal" to have that hence each screen is affected differently.
[Galaxy S II General] SAlmighty:
So is it safe to say that the screen which is affected to a more extent would be deemed as having a more severe manufacturing defect or does none of that really come into play here? I don't seem to be having banding issues like most S2 users are facing. When the display is rotated to a particular direction, lines that would usually appear permanent on sides of the notification area, appear then disappear after a couple of seconds. Is this ghosting suppose to be normal in SAMOLED+ Displays or is my device faulty? Compared to past S2's I've gone through, only the yellow tint seems to be the main issue here. How is 2.3.5 suppose to fix this?
[Galaxy S II General] Tiamath99:
Well, i have issues with yellow stains but they seem to be different from the ones shown here. I have several yellow spots tbat appear in the middle of the screen, they are only noticeable with a white background. The really weird thing about them is that they disappear after a couple of seconds. When you rotate the screen or you change the screen you are watching they appear again.

Does anyone has the same problem?
[Galaxy S II General] SAlmighty:
what firmware are you running?
[Galaxy S II General] Tiamath99:
I'm running the litening 6.1 rom.

Any chance this could be fixed with the 2.3.5?
[Galaxy S II General] SAlmighty:
apparently, many that have done the upgrade are not reporting this issue anyone. i'm waiting for the official release through kies though.
[Galaxy S II General] RjYslf:
I updated via Kies to KI1 2.3.4. The tint on the left side is gone though now the right side is slightly yellow(not even close to the previous yellow though)

Can anyone confirm?
[Galaxy S II General] Tiamath99:
My problem remains the same with the 2.3.5

Probably is the same problem ipad screens had with glue not evaporating properly. Does anyone know if this kind of problem goes away with time? I have the phone for one week now.
[Galaxy S II General] marcadam:
I had bad yellow tint, since flashing CheckROM v5 (2.3.5) and siyan kernel v1.7.7 the yellow tint has totally disappeared. Give this combination a go.
[Galaxy S II General] OgnenLazarevski:
can u share links of CheckRom v5 and siyan kernel v1.7.7
[Galaxy S II General] anshmiester78900:
check the android development section
[Galaxy S II General] OgnenLazarevski:
i've made a decision, and return my phone yesterday.... so i will be writhing here about what gonna happens when t-mobile call me. And if they replace with new phone and have same issue i will have petition and collect 150+ people to sue Samsung. I can't work because constantly read and think about this phone. But it's my bad I've not research more before i buy new phone.
[Galaxy S II General] drm111:
Yeah.... Good luck with that.
[Galaxy S II General] jpxdude:
I can confirm that I had the yellow display tint on the top left of my screen on 2.3.3 and updated to 2.3.4 last week, and it vanished. Where it appeared most apparent was on whites and greys, for example, in the new Market whilst loading, there is a grey background, and the yellow tint would show quite badly. Since the 2.3.4 update it is completely gone.

For me, yellow tint on the left was there since day 1 (2 months ago), so I was shocked to see that it is gone since the F/W update to 2.3.4... :confused:
[Galaxy S II General] htcplussony:
I had read a comment the tint is still there on a fresh boot up and only goes away after the screen powers down and you unlock it.

So I tried this out on googling some grey image in the browser and sliding the notification on a fresh boot before and after unlock. Most weird that is the case.

EDIT opps forgot to say I'm now on xeu 2.3.4 KI4
[Galaxy S II General] tainka:
anyone tried this???

first flash 2.3.4 or 2.3.5 to get rid of the yellow tint on the left side, then use this:

https://market.android.com/details?id=com.netmanslab.sa&feature=search_result to improve even more the appearance of the screen, I added a little bit of blue (+9) and it looks perfect, the greys are more greys and the whites are glowing whites.

I use dynamic screen mode with about 45-50% brightness, no more is needed.
[Galaxy S II General] bandoo:
Read this ages ago, about screen issuses dont know if its been mentioned on here.

http://www.phonearena.com/news/Samsung-Galaxy-S-II-users-in-Vietnam-claim-screen-issues-in-locally-produced-units-Samsung-debunks-it_id21442
[Galaxy S II General] EarlZ:
I've seen that before, I've also done a similar comparison with a few friends.. None of our screens had a single color match and all had different grey rendering and yellow banding extent.
[Galaxy S II General] prinzhernan:
Same with me. My friends and I don't have identical screens. I guess that's just how the tech or manufacturing process is.
[Galaxy S II General] MexxT:
tried screen adjuster, and i can confirm it worked for me!

Tuned up the blue by 13 and red by 5.

now the screen is perfect. no yellow tint anymore.

i think the lack off blue in the screen is the problem...

the gray looks much much better now on lowest brightness. no more green :D
[Galaxy S II General] Dr Zoidberg:
+1 on the combination of CheckROM v5 (2.3.5) and siyan kernel v1.7.7. The yellow is gone. Additionally, I installed Screen Adjuster and set the Blue to +10 and the display is more vibrant.
[Galaxy S II General] SugarySnack:
Any way to get rid of this on CM7/AOSP roms? I want to use CM7 but the yellow tint ruins it for me.
[Galaxy S II General] aussie_26:
Ok, I finally worked out how to install this onto my phone. What baseband is best to use with this ROM?
[Galaxy S II General] anshmiester78900:
Yeah man even i want to know that .. also stable CM7.1 is released for SGS2
[Galaxy S II General] Zenx:
New stable cm7.1 yellow tint still exist. Only the latest experimental build remove the yellow tint due to the kernel with patches. I revert back to experimental build for the time being.
[Galaxy S II General] anshmiester78900:
Can you please tell us the build no . ? :)
[Galaxy S II General] Zenx:
You can refer to cm q&a thread a few pages back. WOOGLESNUGGY build release by codeworkx. This build is not under any nightly.
[Galaxy S II General] anshmiester78900:
ohk so you mean to say the kang buid ??
[Galaxy S II General] DrSlump76:
Hi, does it exist a kernel wich corrects the fadeout on the left side of the screen?
[Galaxy S II General] dikime:
The white edition of Galaxy S2 is "fresher" - are there still screen issues?
[Galaxy S II General] DrSlump76:
Hehehehehe... maybe that in the near future, to select a good working model, we will need to watch the "freshness" of the product.. like in the fish market:

try to watch the "eye", if it's bright and "alive" it's good! :D
[Galaxy S II General] dikime:
Well there certainly is something fishy with all these yellow displays + a lot of people actually go and test several GS2s to find a better one. When I bought my Galaxy S (1), I just checked if it booted up lol :D Was such a perfect phone... too bad I'm a mobile game addict and needed better hardware.
[Galaxy S II General] hirak99:
It could be that new firmwares just compensate for this problem, for example by introducing a blue gradient in the display instead of really fixing it at the hardware level.
