EarlZ,

I know you keep saying that to prevent people from expecting too much from that fix.

However, as we have already agreed the tint is present to a different extent on different phones; the same goes for the fix: it cures the issue to a different extent on different phones.

On my device, I can assure you that the yellow tint is technically eliminated, period. First of all, it's not yellow anymore. And the darker shade, if it's there, is within the general unevenness of the SAMOLED display on flat midtones.

I have just loaded a flat gray background and watched it while turning my phone upside down from time to time. The left side is no darker than the right.

Don't neglect the psychological aspect either. For quite a while used to think my left earphone was louder that the right one. When I swapped them, my right ear received the louder sound, so that kinda proved I was right. But then I stopped wearing them for a couple of months and after that I intentionally inserted them swapped - the left side was louder.

You don't see what really is, you only see what your brain shows you.
[Galaxy S II General] manom18x:
So simple. I thought that I need to press a combination of button in order to calibrate the display.
[Galaxy S II General] EarlZ:
Yes we've agreed on that and I didnt have any doubts on what it does to your phone so I dont see why you need to single me out and be a bit aggressive about your post.

As for the general unevenness of SAMOLED, I guess I had the perfect screen for the Galaxy S1 (and got spoiled) as no matter how I look at my old S1 there are no unevenness on grays/flat colors:)

On my phone I see that there is a difference on the left side to the right side on the stock dialer and stock keyboard and usually on the popup textbox that super user shows, left side is dimmer even if its 0.01% I've done a blind test by covering having someone cover the top and bottom part of the phone so I cant tell the orientation, I've never mistaken which side is darker by 0.01%

Outside of those scenarios I can cant tell anymore with my first phone though even on the inbox and photos can I tell which is the left and right side.
[Galaxy S II General] anton79ru:
Oh, I'm sorry if I sounded aggressive, mate. That wasn't even close to my wildest thoughts. The reasons why I singled you out are: 1) I like exchanging opinions with you; 2) you repeatedly said the recent ROMs only alleviate the issue, not fix it, whilst my point is, depending on the device, there's a good chance flashing a new ROM can cure the problem, not just ease it.

Again, my sincere apoligies - displaying any negative attitude to anyone in this forum is just not what I'm here for.
[Galaxy S II General] EarlZ:
Alright, understood :)

I do hope on my 4th exchange I get a screen like yours that wont have any darker left side.
[Galaxy S II General] anshmiester78900:
Hmm i like my phone very much i love it also even my phone has yellow tint but its hardly noticiable ..
[Galaxy S II General] EarlZ:
Since your using a 2.3.5 ROM, is the kernel still based on 2.3.3 right because you can tell you have a yellow tint, of course its not noticeable to some but it would be better not to have any discoloration right especially knowing that the previous generation SAMOLED screen didnt have this flaw, but hey dont let my expectations (relatively high) be yours ;)
[Galaxy S II General] anshmiester78900:
Umm bro can the level of tint be lowered down as the people here are saying .?? Im on cognition 1.42
[Galaxy S II General] Tinderbox (UK):
I have had three S2 , first one went back for overheating, second for pink spot, and both had the yellowish left side but only slight.

My latest S2 the left side is only very very slightly darker that the right, but no sigh of yellow or any other colour. :)
[Galaxy S II General] EarlZ:
Yes with a 2.3.4 kernel built from the source code, your signature says your on andriod 2.3.5

The severity of the yellow tint really varies from phone to phone, at least you have 1 good phone out of 3.. Just keep exchanging those and your bound to get lucky.
[Galaxy S II General] anshmiester78900:
Lol no now im on cognition rom n its 1.42 so do i need to flash to a stock firmware to see the changes
[Galaxy S II General] sebarkh:
because MIUI is based on 2.3.5. Period :)
[Galaxy S II General] EarlZ:
No need to flash a stock package, just use Chainfires OXA_KGx or OXA_KHx

Im not exactly sure whats your reply for.
[Galaxy S II General] anshmiester78900:
thnx +1 for the reply :D :)
[Galaxy S II General] EarlZ:
Id like to share this display weirdness on my 3rd phone that I've never been able to properly understand.

When I pull up the dialer the grey boxes for 1,2,4,5,*,0 seems to be a bit darker (or reddish) while 3,6,9,# appears to be in a lighter shade of grey. The numbers on the dial pad dont appear to be darker or reddish so If i rotate my phonte to the right puts me in landscape mode and brings 7,8,9,*,0,# to the supposed to be lighter area but I can confirm that all the dial pad buttons now look about 99% the same... With this I tested it on the stock virtual keyboard and expected the same result but only letter P and L had the slightest hint of being actually darker, if I view white images or the ring tone selection menu I dont get any hint of anything being darker or reddish, infact im getting far better white levels compared to those cool and warm displays.

This is not a complaint but Id like to understand whats going on aside from the native unevenness of SAMOLED+
[Galaxy S II General] nomnompie:
I have just recently noticed something stupid. I had previously said that the yellow tint did not return on reboot, but I see now that on both my phones it comes back on reboot but goes away after the first screen lock. I could have swore I purposely checked this already and this wasn't the case. Earl can you confirm?
[Galaxy S II General] EarlZ:
Yes I can confirm on that, its how the fix works.
[Galaxy S II General] jasdev:
I dont have the problem
[Galaxy S II General] EarlZ:
Who said you had??
[Galaxy S II General] SaneinOne:
I've experienced a worsening of the issue after flashing latest HC kernel which leads me to hope that it is in fact more of a software issue than a hardware one.
[Galaxy S II General] anton79ru:
Same thing here. I'm starting to think there's an algorythm in the firmware that, once loaded, detects what kind of screen you have and then decides whether to apply the fix or not.

At least I wish it to be that way. Everyone can screw up, but not everyone can find an intelligent way out.
[Galaxy S II General] C64c:
I'm getting a replacement from O2 UK. I will receive the replacement tomorrow morning and I'll let you all know if that has the Yellow Tint or not.
[Galaxy S II General] nomnompie:
Yeah, I knew about the lock/unlock, but I told some people that it did not return on reboot... :eek::o oops. Could have swore that was true as I tried it many times but I guess I wasn't paying attention. :p
[Galaxy S II General] darkfire_bg:
Hi guys, can u point me an app, which can control minimum brightness(i dont want my phone to go below 10-20%). And also can i remove dimm screen before locking? It's like last 5 seconds(if u are on 15 secs lock from display settings?). Yellow tint rly annoys me.
[Galaxy S II General] EarlZ:
Try auto brightness pro, you can manually set it at what ambient light it returns back to manual brightness which you can also set to what %
[Galaxy S II General] rockrag:
I have a vertical line running along the right side of my phone and a yellow tint issue. Its been 20 days since i bought it and discovered the problem only a couple of days back. After reading quite a lot of info in this forum, I've decided to get mine replaced now. Question is, will they accept my problem and replace it being 20 days from purchase? Only disadvantage is that i reside in India and Samsung has a poor service here. Please Advice! Thanks.
[Galaxy S II General] EarlZ:
Yes they should be able to at least replace the screen, 20 days till you noticed the vertical line? Can you post photos of it ?
[Galaxy S II General] EarlZ:
- wrong post -
[Galaxy S II General] C64c:
I have the replacement!! The yellow tint has gone, but a slight darkened area is present. Better than the yellow. But what is it I wonder??
[Galaxy S II General] Tinderbox (UK):
Yeah, my first two had the yellow area, my current one does not have any yellow , but the left side is very very slightly darker.
[Galaxy S II General] nomnompie:
What firmware version did your replacements come with?
[Galaxy S II General] rockrag:
No, i noticed it on the first day itself but i ignored as i was too busy investigating the phone. Now after reading a lot in here, I am getting irritated by it day by day and finally decided to send it off and try my luck. Yellow tint doesn't bother me much but this line does at times. I dont want them replacing the screen, only if they can replace the phone itself. I have a wifi weak signal and a pink spot problem too.

My display at brightness levels 0%, 50% & 100% in a dark room.

[Galaxy S II General] transbean:
I also have vertical line, just notice it last night when setting my alarm clock

in my room it's dark at the time. So i try to reboot my phone because i thought

it was caused by software issue but as the phone reboot vertical line become

very visible.

I can also see the vertical line using LCD test(*#0*#) and choose front camera

test, this must be run in environment with low light, i also saw many small blobs.

Strange thing is my vertical line is also in the right position same with rograck,

i suspect it couled be because manufacturing fault when assemble the screen.
[Galaxy S II General] bala_gamer:
So far i have flashed 4 custom roms and all of them had yellow tint problem, when i reverted back to stock XXKH3 the problem is gone.

No custom rom,No yellow tint!!!

This is my case, as like others said i may be having the right screen in my S2!! But since custom roms is making my screen to have a yellow tint, i strongly suspect the source code from which the roms are compiled, so once we get a good source code this problem will surely subside.

One more thing, just flashed Ninphetamine kernel after flashing the stock rom, the yellow tint is back. So surely it has to do something with the source code being used.
[Galaxy S II General] EarlZ:
Custom kernels are still based on 2.3.3 codes so you wont get the yellow tint fix.
[Galaxy S II General] bala_gamer:
You are right earlz... Atleast some of us can relax back that it is indeed a software problem and not hardware related
[Galaxy S II General] DrSlump76:
Is it possible that the display tint correction is related to the low level drivers? These driverse should be integrated into the linux kernel, so they should be open source.
[Galaxy S II General] EarlZ:
From what the devs speculate its a low level driver fix to alleviate the yellow tint from hell.
[Galaxy S II General] SaneinOne:
I'm holding out on returning/exchanging my device in hopes that it is indeed a software issue that will soon be resolved. I have experienced varying degrees of the issue with different stock/custom ROMs and kernels so fingers crossed!
[Galaxy S II General] DrSlump76:
Well i think that i can live with my tinting until the new update is avaible. What is really annoying me is the serious frame drop that occours during the indoor filming :mad:, i hope that this is fixable too, without bringing my unit to a repair center :(
[Galaxy S II General] bala_gamer:
If you have the tint issue with the latest stock roms, then most probably you will be having some defective screen, as the latest firmwares are being built from update source code which has not yet been released to public
[Galaxy S II General] itaykoren:
I just installed KG5 (2.3.4) and this is how my screen looks like when I turn the brightness down.

Do you think I should get it fixed?

http://imageshack.us/photo/my-images/204/img2502k.jpg/

Upper left corner concerns me...

I would be happy to hear your thoughts on this one.
[Galaxy S II General] Lulabby:
It looks bad. Try kh3 rom, if the problem exists, you should take it back the shop.
[Galaxy S II General] itaykoren:
Thanks for your reply.

I'm probably going to replace it as I believe KG5 should have done the trick (which it hasn't).

Just checking, you were referring to the upper left corner that's a lot more yellow than the right corner when you said the screen looked bad, right?

(I hope you didn't mean the many vertical stripes as these are only in the photo, and not present in reality).
[Galaxy S II General] Lulabby:
Yes, I meant the yellow circle at the upper left corner. As you sad, kg5 kernel should do the trick but it did not so definietly return back the shop.
[Galaxy S II General] C64c:
I give up on the s2. Sent it back to o2 and to cancel my upgrade.
[Galaxy S II General] prinzhernan:
My yellow tinting appears when the phone is at 0-10% brightness. Any higher than that, it disappears. Is it really a fault or is it just really the nature of SAMOLED+ screens?
[Galaxy S II General] EarlZ:
Not really sure but in my own opinion its a fault since the previous generation SAMOLED on the S1 and Wave didnt have this funkiness, Sammy is rumored go back with pentile display on the SAMOLED HD it could be the reason why.
[Galaxy S II General] anshmiester78900:
Well my phone used to have Yellow tint problem (only little ) but after flashing with leomar's rom its gone :D
[Galaxy S II General] prinzhernan:
It could also be that pushing the pixel count and effective resolution in samoled+ causes this flaw. And that the reason why they are returning to samoled hd for larger formats is that it's more cost effective vs making samoled+ hd. Since all units have the tinting in different degrees, then it must be a limitation of the technology and not a flaw or exception. Isn't it that a flaw is a flaw if only a few units exhibit the symptoms? Since most if not all units have it then I guess pushing the pixels higher causes this tinting and is thus a limitation of the currrent product production line. I don't think you can really compare samoled to samoled+ as they use different tech (pentile vs. full RGB).

Right now I'm confused. Before seeing this forum post I was content with the screen. Now I still am as I don't use it below 10 percent brightness but there is a nagging thought in my head that it has a yellow tint.

When I went to the Samsung service center they didn't really pay attention to my screen complaint since in the lcd test screen (*#0*#) there were no dead pixels, and there was no yellow tint on on the white screen test (maybe because the screen test does not show colors below 10% brightness). They admitted my phone because of the heat issues when charging, which was my initial complaint to begin with.

I guess in the end it's all about if we could accept the limitations of the samoled+ technology since at higher brightness the yellow tinting disappears anyway. Does using the screen below 10 percent brightness count as normal usage? On that I'm really not sure.

I hope I've not offended anyone I was just trying to think reasonably. Yes, we do expect a perfect screen with the amount of money we paid for this device but then again we have to balance it off with actual usage of the device.
[Galaxy S II General] BarryH_GEG:
You seem thoughtful and your post was very considered. But comments like the one above are what make it difficult to take display threads/posts seriously. The general consensus is that if you have to create artificial and non-realistic conditions to demonstrate a problem, then it's not really a problem. Seems like the Philippines got more than it's fare share of phones with screen issues. ;)

P.S. - The SAMOLED HD, even if Pentile, will be pushing tons more pixels than the SGS2 based on both the size of the screen and it's resolution. So if a high pixel count is causing display issues, it's going to get worse not better.
[Galaxy S II General] EarlZ:
A white screen test wont show the yellow banding on the left side but on a normal usage like using the dialer, or composing an SMS message its very obvious on most of the units I've seen. I honestly dont know whats really causing this banding effect all I understand is that samsung has probably lowered the quality assurance on the S2 screens since it will be just a 6-7 months product before another new device comes out anyway.

I use my phones indoors alot so 0-15% brightness is pretty much common to my usage, those who probably fix the brightness at 50-90% will never have to deal with this issue.

I was never contented with the screen even before reading this thread from page 1, after I got my 2nd replacement I started to read this page from page 1 to the last, currently on my 3rd phone and waiting for approval on the 4th one, Im a bit confused right now if I should get a refund or just keep the 4th replacement if its better and accept that there are random screen defects on the batch that we've been getting in the Philippines.

Personally Im not looking for a perfect screen but something with in the advertized specification, coming from the previous generation SAMOLED screen I also expected that the SAMOLED+ will be better in all aspects and not be better in 1 and fall flat on all others, I do hope that SAMOLED HD will be better so we can put this nightmare behind.
[Galaxy S II General] EarlZ:
Do take note that its only a general consensus here in XDA, I've never seen a unit thought that I needed to create a special condition to show this issue consider that the service center is extremely well lit and the screen might be even blasting at 50-65% brightness, the last time I went to the service center they popped out 4 phones all with different degrees of banding It only look me about 5seconds to show them the issue, both sales and tech personnel agreed that they do see the issue and even popped out a demo unit for the galaxy S1.

But since the 2.3.4 kernel alleviates this issue, this is behind me already but other screen problems are plaguing my 3rd phone which was not on the first two :(
[Galaxy S II General] nunomeneses:
Yeah, i'm on the 5th unit and this one has a blue tint that can be seen with angle... Never had this but i'm keeping this one cause I'm tired of trading really...
[Galaxy S II General] EarlZ:
Had that on my first phone, its believed to be a thicker oleophobic coating causing that blue shift.
[Galaxy S II General] itaykoren:
Yeah, well I also flashed KH3 just to be certain, but it seems I got a bad screen as I can clearly see this terrible yellow tint even at auto brightness.

It seems it's going back to the shop...

Thanks for the advice.
[Galaxy S II General] EarlZ:
Send it back and let them see and confirm the issue.
[Galaxy S II General] KayvinM:
I need some feedback regarding an issue I'm having. Well it's not really an issue so much as annoying. I'm not sure if this is a banding issue or what, but on grey backgrounds that has a fade (dark grey to a light grey) the phone shows the fade with a pink or purple hue instead of the actual color. It's more noticeable when the display brightness is low. Thing is, I'm not sure it's a hardware issue since the pink spot moves with picture and isn't in the same spot in the screen. I'm running stock Bell KG2 2.3.3 firmware. Has anyone else come across this?
[Galaxy S II General] EarlZ:
I've noticed that too, I think its either because of the technology limitation on the SAMOLED+ ( The first gen SAMOLED didnt have this annoyance ) or it must be due to the 16bit color rendering.
[Galaxy S II General] bala_gamer:
Dude , are u sure there is no yellow tint after flashing a custom rom?
[Galaxy S II General] KayvinM:
Thanks, ya I guess I just have to live with it since it seems less of defect and more of a limitation like you said. I just got a little paranoid since I'm on my 3rd replacement and just now noticed it. Funny thing is I was going to post a screen shot and when i uploaded it to the computer it did not have the purple spot, but it was evident when viewing from the phone. Still love the phone though :D
[Galaxy S II General] bala_gamer:
You are right!!!! This is the only rom that doesnt give me the yellow tint.
[Galaxy S II General] rockrag:
Hi, what you mean? As in even the KGx and new KH3 removes yellow tint on left side and creates a darker shade on it. Do you mean Leomar's rom does the same or it removes the yellow tint and spreads even shades over the entire screen without dark shades? Thanks.
[Galaxy S II General] bala_gamer:
With dlev2 custom ROM the screen is looking cool overall, and no more yellow tint..
[Galaxy S II General] Makador:
New to the forums so go easy please. I have just recently bought 2 SG2's first one died with reboots and overheating issue (unlucky I guess) but it had no screen issue. The second has the yellow tint issue but it is not that bad. Overall the contrast is not as good though and the screen is slightly more yellow at low brightness. They came from different batches.

The first one is being replaced/repaired but I'm not sure what to do with the other. Reading through here some people seem to think it is hardware and others seem to think a kernal update has solved the issue. I'm in Aust and Samsung have not released the 2.3.4 update here yet so haven't tested that.

Would be great to have more confirmation of whether this is hardware or software.
[Galaxy S II General] DrSlump76:
It's an hardware issue. The modified kernel drivers only applies a color correction based on some screen data.
[Galaxy S II General] hussam1988:
no problem here
[Galaxy S II General] rockrag:
News News!! I went to the samsung service center today and showed them the problem i had. I had a vertical line running along the right side of my phone, yellow tint (ofcourse) on the screen and a camera pink spot. Since my phone is already 25 days old i was worrying if they will accept replacement. I somehow convinced them about the issue and they were understanding too. They themselves knew about the problems and told me that i could replace but even the new phone can contain these defects. So they gave me an option of replacement or refund full bill amount. I happily opted for refund as we have Samsung galaxy S2 LTE upgraded version along the line coming. They stated that i will get my refund within one month. Waiting till SGS2 LTE releases :D. Trust me after 25 days i could get refund. :P
[Galaxy S II General] DrSlump76:
I'm happy for you. This can only mean that they are aware of the problem before to sell the device. The new device is a demostration that this was a bugged one.
[Galaxy S II General] rockrag:
True. Very true. Why would samsung introduce a upgraded model of sgs2 so quickly. hopefully they should have fixed all the bugs of the original and releasing the perfect one.
[Galaxy S II General] BarryH_GEG:
You're all delusional. I typically go through 2 phones a year and have experience with all the manufacturers. Every phone has issues. And as phones get more sophisticated there will be even more. The next SGS may have a different set of issues than the SGS2 but if you think it'll be perfect keep dreaming. And despite all the negative commentary in this thread, Samsung's sold 5MM and it's about to launch in the U.S. where another 3MM will probably be sold. While it may not be "perfect" to some it would certainly seem there are a lot of happy owners.

And the answer to the question about why Samsung's introducing another model is simple. Offering a 4.5" screen is a competitive move to match HTC and Motorola. It's the same reason there will be a 3D model. The SGS2 isn't being discontinued - they're still selling a version of the SGS1 that they just updated. And the 4.5" display is the same one used in the Infuse and made with the same technology in the same factories as the SGS2 screen. So whatever issues exist today will exist until the next evolution of SAMOLED which is supposed to be the 720P SAMOLED HD technology introduced in the Prime.
