[Galaxy S II General] nomnompie:
Are they letting you return these or are you just keeping them all??? :eek:

If I had a screen that looked like the one on the right, I would be happy. At least the entire screens color seems balanced. I do not see any brightness difference or yellow on it.
[Galaxy S II General] Natascha303:
right, no yellow at all. pure grey

but this batch has got a problem with the display glass, on the left side above in the corner. the display glass is not insert, it is just over the side.
[Galaxy S II General] ithehappy:
Absolutely U-N-B-E-L-I-E-V-A-B-L-E.
[Galaxy S II General] DuoM:
This is a farce!!!
[Galaxy S II General] Lownita:
Man thats annoying, I guess if I would choose to change mine because of yellow tint, I would get one with either the same or another problem, too :(

Hi,

I remember the FB page about the issue. Subscribe as a petition mark.

[Galaxy S II General] stijnr:
Hi,

I just got picked up my replacement from MediaMarket today and the sales guy said it was from the new batch. Although the color is a bit less yellow overall (I looked at them side-by-side in the store), it still suffers from the yellow left side quite heavily.

I'm not sure what I'll do next. Discuss with MM and see if I can keep exchanging until I get one the is a lot better, or send it to Samsung (after they fixed the problem), or....
[Galaxy S II General] Lownita:
Mine looks exactly like that!
[Galaxy S II General] jvidia:
It's weird so many devices like this for a simple assembly problem.

It looks like a serious engineering failure!

My local store in Portugal has this issue raised on Samsung.PT ... no feedback yet.

PS: FB like done :D
[Galaxy S II General] -Anthony-:
Dammit!!

I would to buy this smartphone but I hate this issue. I had a SGS1 with a green stain on the bottom of the screen. When sent it to assistence (with a good photo who showed the issue), here in Italy, the smartphone has come back with the same issue after 30 days! They had upgraded the firmware (no sense...).

I'm scared that with this one I will have the same troubles. So I'll wait some days after.

Dammit!!Dammit!!Dammit!!Dammit!!Dammit!!Dammit!!
[Galaxy S II General] sierra16:
Same issue

Hi there, I also have this issue, altho very slightly and not as bad as some of these images. mine is only on the top left side. But still now i know its there very annoying. how do i contact samsung regarding this? there is no direct email?

I figure the more people who complain of this, surly there will be a product recall for defected models. this cant be good for there image as its all over the net now.
[Galaxy S II General] noobdeagle:
hmm well im about to buy an SGS2 and this is a little bit of a concern however!,

i find this whole thread kinda funny cause most photos are terrible quality so its hard to really get an idea of the issue cause pictures are such low quality and the only high quality ones so far the issue seems unnoticeable....

while im not debating if an issue exists it clearly does but providing evidence of such poor quality makes it a bit questionable ......do people not own decent cameras other than phones ?
[Galaxy S II General] jvidia:
Do you need more proofs ? I think the quality of the photos is good enought to see the problem, but if it was not enought I have this problem so I believe people.

After you buy the S2 you can show us a GOOD QUALITY PHOTO! OK? ;)
[Galaxy S II General] noobdeagle:
no problem ill use a DSLR ...easy

lol its not that i dont believe it exists its just that someone on here used a DSLR and the problem wasn't noticeable at all yeah it exists but its hard to get an objective idea of the issue based off of photos here leading me to believe its more pronounced due to poor camera quality. cause ive been looking at reviews and the high quality photos in reviews don't seem to show it.
[Galaxy S II General] MartinNH:
As someone else wrote in here, the human eye is much more sensitive to small colorvariations than most cameras. So a problem like this might be easier to spot in real life. At least that's the case with my phone..
[Galaxy S II General] jvidia:
That's it!

I talk about what I see in the phone, not from pics.
[Galaxy S II General] sierra16:
anyone know the email?
[Galaxy S II General] hg3atintin:
I just sent back my sgs2 for a new replacement. I had a weird light ring on the screen and blueish hue.

Will get a new one in 1-2 weeks.
[Galaxy S II General] nomnompie:
I also used a DSLR but I didn't bother posting pics cause I had a difficult time getting the issue to show clearly on anything except the status bar or a grey screen. But I can plainly see the yellow during normal use, on the web browser, viewing photos with light colors, on anything blue, etc. etc. etc. and it drives me mad.

You are correct it does seem easier to see in person than on camera, but I believe most of the pictures do show the problem fairly well. If you had a SGS2 in your hand you may have a better idea what to look for, but when you look at the pictures you can tell its there. :(
[Galaxy S II General] derby_sv:
I'd like to hear a few words from developers about idea to correct the yellow-darken gradient by software. If it's possible, I think that many people will donate this work...
[Galaxy S II General] deanwray:
wow

This thead is huge, must admit I haven't read through all of it.

Neways, this yellow thing, from the posts I've skimmed and seen multiple shots of the touchwiz status bar and drop down, I see graduation over it. I don't seem to have a massive problem with mine, well, I know there is a very slight tone difference left to right, but not really noticable.

Neways, has some1 check the resource graphics of touchwiz 4?

also:

I actually took some multi-exposure shots with my lovely canon 5dmk2 with the unit on test mode and looked at the RAW images while altering the exposure and curves. The lighting patterns are not as consistant as I would have hoped but at 80%+ they are not noticable.

may go now and set aside a few hours to read through this monster thread :)
[Galaxy S II General] dem000n:
+1

I would pay for that too :)
[Galaxy S II General] nomnompie:
Raging here, (Disclaimer: this post is a little out of context and exaggerated so please nobody take it personally)... but I'd much rather the money I already paid to samsung, be for a phone that doesn't suck to begin with. :p

SGS1 - GPS Fail

SGS2 - Screen Fail

Samsung - WTF!?
[Galaxy S II General] BarryH_GEG:
Actually, if you go back and read the thread, the OP said the opposite. You're the first person in eighty some pages to say the issue is worse with the eye than the camera. I can't see the issue on my phone unless I take pics of it. I've posted screen shots from my phone a couple of pages back.

And to recap once again, Samsung's been contacted, the online media picked up the story and linked back to this thread, and there's a FB page floating around out there. They haven't acknowledged the issue, newer production batches still have it and for all we know will continue to. It bothers some people more than others and if you're in the former category you should re-evaluate your purchase. If you're a new purchaser and anal about your display, go back and look at the posted pics both of grey and real life screen shots to see if you can live with it. If you can't, this isn't the phone for you (at least for the time being).
[Galaxy S II General] jvidia:
Very easy to say ... but after buying it, and the "return/refund to store" time passed what do we do if Samsung does not acknowledge this issue?

Sell it and lose 100€/150€ ?

Yeah it a great dual core phone , no question about it but that's not all.

Imagine buying a Porche and it comes with the front shield glass scratched. :mad: That's how I feel.

If I didn't want a top gadget (performace/style/image quality) I could have bought for instance on LG P500 for 150€.

:cool:
[Galaxy S II General] BarryH_GEG:
This is a bit exaggerated. I'd hardly put this issue in the same league as the GPS issue(s) on the SGS1. While the screen issue shouldn't be there, the majority of people aren't bothered by it. I (and others who I asked to look at it) didn't know my phone was affected until I took pictures of it. If it wasn't for this thread I would have been blissfully unaware. I know this thread has gotten painfully long but if you go back and read it the everyday impact of the issue is pretty tame. Keep in mind it may be a design issue and a compromise Samsung was willing to make in order to claim the title of "thinnest phone." If that's the case, what we have it what we'll be living with. Make your ownership choices accordingly. Ranting and railing isn't going to change anything. It certainly didn't with the SGS1 GPS issue.
[Galaxy S II General] BarryH_GEG:
Live with it or sell the phone. Personally, the issue doesn't bother me. It annoys the crap out of some though. If you're going to hate your phone every time you look at it then sell it. I lost a ton of money on the O2X/G2X because it was a piece of crap and I couldn't stand it. It's your call. You'll get support, sympathy, and encouragement here but it's not going to fix your phone.
[Galaxy S II General] stijnr:
My photos were shot with a DSLR (5mp). My actual photos are a lot larger, but the forum resizes them to a size of 100kb. I can upload the larges ons if you want.

Because you have to shoot in a dark room with the brightness of the phone all the way down, it's hard to keep the camera steady.
[Galaxy S II General] nomnompie:
I know... Hence my little "disclaimer" in my post. :o

Basically just a colorful way of saying that I wish an 800 dollar device would actually have a quality screen free of defects. If you think about it, though the device is still functional, if samsung ignores this issue as they did the GPS issue, then I will probably dump the replacement GS2 that is due to me sometime, but something else, and not even give the SGS3 so much as a glance. Track record is usually everything when dealing with companies. But yeah, still just venting.

The issue was bad enough on my screen that it made my brain twitch looking at it. Especially since visible mostly while not on max brightness, which is pretty much ALL the time in my house.

Bottom line is to me it seems Samsung should man up and fix it. We shouldn't have to rely on developer band-aids to fix things that manufacturers should be able to make sure never exist in the first place.
[Galaxy S II General] ithehappy:
Well said.
[Galaxy S II General] Seabass1:
While in an ideal world Samsung would do that, my guess is that they simply don't care. Unless enough people return their phones and hurt Samsungs cash flow they'll just carry on regardless, unfortunately that seems to be the way of the world these days.
[Galaxy S II General] BarryH_GEG:
Want to feel better? Go look at the Sensation, O2X, and G2X forums. The Sensation has dust under the screen, horrible viewing angles, touch response issues, and some have an overall yellowish tint. The G2X/O2X have LCD light bleed ranging from noticeable to OMG. And that's just the display issues. Overall, of the newer high-end phones to launch, ours is the least screwed up. It's by no means an excuse for Samsung not getting it right but, based on recent phone releases, it would seem all manufacturers are getting further from perfection not closer. Maybe its because of all the crap they're trying to cram in to too small a space. If every new phone from every manufacturer comes out hosed in one way or another the only solution for perfectionists is to hold on to your single-core legacy phones forever. We XDA'ers are not a representative audience though. The masses probably notice or care about a fraction of what we do. Samsung sold an additional 5MM more SGS1's after the GPS expose; so much for the power of XDA and the online media. That's the price we all pay for being cutting edge ;)

P.S. - With all the SGS2 issues that have been exposed, I still can't think of a phone currently out that I'd want to replace it with.
[Galaxy S II General] Sp1tfire:
+1 on that. My girlfriend was a bit impatient and bought an Optimus 2X cause they appeared first in our country. After messing around with it, i was 100 % convinced i must wait for S2 to be launched in our country, though i never had a Samsung phone before, been a HTC fan for years. Between Optimus 2x and S2, i would choose Samsung any second :)
[Galaxy S II General] nomnompie:
Yeah, you make a point that is true but very unfortunate. The reason I held off from upgrading my HTC Hero for so long is because the ONE lingering problem I have with Android, that being: Every device seems to have a rather glaring shortcoming.

To name a few.

HTC Desire - Multitouch issues

HTC Desire HD - small battery

Nexus S - No SD card slot

Optimus 2x - horrible stock software, reboots, etc

Plus the other issues you mentioned.

Who knows if manufacturers make some of these on purpose, or by mistake. I would guess an obvious mix of the two.

So now I have finally bombed the money for a SGS2... and it has a marred screen. *disappointed face*. I could go for the O2x, but well, lets face it, like you said, look at the forums for that and the sensation. Basically, there is no perfect way out.

So dammit why can't manufacturers check this stuff before things get out. I do believe if we do like you say, make a big enough stink that sammy starts losing money, that just might push them. ;) We may not be a large enough force alone, but if every smaller community reports it and we all get wind of it from each other we can multiply our force dramatically!:cool:
[Galaxy S II General] julandroid:
I had a similar suggestion as well. If the issue is the same for every display then I can assume that the problem is actually with the quality of every sub pixel calibration. The software-post calibration might be possible if every phone's memory (or Samsung in their databases) keeps the original calibration values.

That is a plus for the SAMOLED+ displays - you can calibrate each and every pixel - the question is - does Samsung keep record for each display they made and is it possible to perform an online calibration via Kies?

It's true that human can detect such a small deviations in the colours and also represent colours (adapt eyes) in the dark much more accurately than most DSLR in auto mode. The problem with digital cameras range from white-balance, through long exposure time in dark and ends with terrible automatic colour balance, which converts colours from the real one to those inaccurate you can see virtually in every single post in this thread. Get the facts straight: what you see on those pictures are overexaggerated for sure due to limitations of the both DLSR hardware and its post processing (build-in) software.
[Galaxy S II General] renton82:
In galaxy s the k13 speedmod kernel allows to change the screen colour temperature, maybe the same thing could be done here...maybe only for a part of screen...
[Galaxy S II General] BarryH_GEG:
The O2X/G2X is as cursed a phone as ever existed. Every radio (2/3/4G, Wi-Fi, Bluetooth) on every LG high-end phone is screwed up. Look at every one of the respective forums. The O2X had reboot problems for months in the EU and they turned around and launched it in the U.S. with the same bugs six months later. There's an old adage, "I used to feel sorry I had no shoes until I met a man with no feet." You guys try living with an O2X/G2X for a couple of weeks - it makes the SGS2 look like nirvana. Maybe that's why I've become less picky. ;)
[Galaxy S II General] maeman:
That's just a piece of paper.

Are you another iPhone fanboy? jealous of Korean tech supremacy?

By now, Samsung might be mp manufacturer no.1. does it hurt you?
[Galaxy S II General] indrajit_pande:
Guys, if you can help me understand if I am seeing a dead pixel on my SGS2 screen. I find a white pixel when i check a black background on the screen. I used *#o*# to run the tests. When the screen is red or blue or green in screen test mode, the white pixel truns to the test colour but still it is faint and I can easily spot the pixel. Please let me know if it is a dead pixel and if so what should I do? Thanks in advance for any help.

Regards

Indrajit
[Galaxy S II General] maxx001:
I have the same concern. My screen shows a strong blue tint as soon as i tilt it just a little in any direction. My girlfriends SGS2 does not have this problem at all.

I don't care about the yellow tint in the left side as this is not something you really notice in everyday use.
[Galaxy S II General] derby_sv:
He should simply disable the flash before shooting :rolleyes:
[Galaxy S II General] godutch:
There is a bug in auto white balance with some camera/firmware/ cam firmware combination, I got that pinkspot on both my front and rearcam, disable auto white balance and the spot disappears
[Galaxy S II General] Sleepycat3:
Nothing wrong with showing proof of the pink spot. I found that it depends on the lighting conditions. Under fluorescent lighting, I don't get the pink spot as per my photo of my "just a piece of paper" below. But I can find conditions where the pink spot does appear on my phone. Heck, under the same conditions, I can just change the white balance from Auto to Sunny and I can get green spot! Which do you prefer? Pink or Green spot?
[Galaxy S II General] stijnr:
[off-topic]

Erm, what am I missing here, don't you see the pink hue in the middle? The piece of paper was white and no flash was used.

The pink spot does depend on lighting

My replacement phone has the pink spot less pronounced and in most lighting conditions it almost disappears after auto brightness adjust time.

[/off-topic]
[Galaxy S II General] eallan:
Well some of us would disagree.

Why the off topic about the pink Hue? Make a new thread for that.
[Galaxy S II General] Jade Eyed Wolf:
Not to be rude or anything, but this isn't the thread for the pink spot issues some people are having with their camera's. This thread is for an issue with discolouration of the screen.
[Galaxy S II General] Jade Eyed Wolf:
Suffice it to say, the issue is there, and it seems to be universal to all the devices which have currently been made. Granted, there does appear to be some degree of variance, whereby the problem is more apparent on some peoples' devices than on others. Also, the severity of the problem is really kinda subjective. For some people, even the slightest defect on a $700+ device is intolerable, and that's perfectly fine. For others (myself included), although the issue is there, it's either not apparent enough to cause any huge concern, or they just don't care enough about it to return the phone due to all its other redeeming qualities.

Personally, I quite liked the idea of finding some kind of software solution for re-calibrating the display, or perhaps applying some system-wide gradient filter that cancels out the tint on the left.

Until then, I've got mine at 100% brightness, because let's face it, at full capacity, it IS a brilliant display, and on my device at least, the yellow tint goes away completely. As far as battery life goes, I still get through each day of normal use with plenty enough battery to spare. It's not a big deal for me.
[Galaxy S II General] stijnr:
Well, I called the MediaMarkt today (large reseller in Europe) because my replacement phone which I picked up there two days ago also had the yellow discoloration. When I went there three weeks ago to show the issue to the people of the store to get okay'ed for a replacement, they said I was the first to return the phone. When I called them today they said that lot's of people came and returned their phone because of the yellow left side. Not only at that MM location, but at others too. They advised me to bring the phone in and have them send it in for repair (takes approx. two weeks) because probably their complete batch has the problem.

Hopefully this reseller problem will reach Samsung and urge them to do something about it.

I think I read in the thread somewhere that someone already sent it in for repair and got a phone back with exactly the same problem, not really hopeful...
[Galaxy S II General] BarryH_GEG:
Let me tell you a little story about manufacturer obliviousness and the lack of consequences for selling ****ty hardware and software. The LG O2X launched in the EU about eight months ago on 2.2. From the first one sold the phone suffered from random reboots, batteries overheating, and screwed up 2/3/4G, Wi-Fi, and Bluetooth. It took LG (via Denmark) five months to even acknowledge the problem by responding to an online media outlet with an e-mail that said "a small number of our customers have reported issues which will be resolved via an update." I'd guess the "small number" is somewhere between 50-70%. T-Mobile U.S. picked up the phone as the G2X to sell as a vanilla android phone. Foolish me, I thought there's no way LG and T-Mobile would launch the phone without the problems being resolved. Wrong. T-Mobile added a ton of crapware to the phone that made it worse. In addition to the above issues the LCD screen bleeds, sometimes from all four corners. People began exchanging the G2X three and four times in an effort to try and get one that worked. Instead of acknowledging the problem, T-Mobile and LG started to hype 2.3.3. as a way of "improving the phone's performance." That was two months ago and there's still no update. T-Mobile's solution to minimizing complaints and exchanges? They pulled the phone off their website and out of their stores and said "they were experiencing supply shortages." Really? The G2X is the only phone on the planet that they can't make enough of? It may come back with 2.3.3. or it may be gone forever. Who knows.

So, the moral of the story? Big companies don't care. It's cheaper to ignore a problem than admit it because none of them want hundreds of thousands of handsets returned or exchanged. And the consequences to LG of selling ****ty hardware and software? Verizon, the biggest U.S. wireless company, just added the LG Revolution to their LTE line of phones. Guess what? According to their forum it's having the same issues as all other high-end LG phones. And here's a real kick in the ass, LG's rumored to be the hardware provider to Google for the next Nexus phone. Sort of sucks, doesn't it?

So back to us. If LG can get away with what they're doing to O2X/G2X owners without consequence, what incentive does Samsung, HTC, or Motorola have to behave any differently? None. So, at some point, Samsung may change something on the SGS2 to make the banding issue go away. If they do, taking the above in to account, it'll be done quietly and discretely. That's a lot cheaper than replacing the screen on a million phones.
[Galaxy S II General] B3311:
You're not allowed to say that on this thread. You have to scream like an Iraqi widow at her man's funeral.

Then - and

ONLY

then - will you satisfy the drones on this thread.

Don't believe me? Check my posts here. And I don't even have a yellow tint....
[Galaxy S II General] BarryH_GEG:
Now that's funny (no offense to our Iraqi SGS2 owners).

While my view is similar to yours and others, I do sympathize with eallan and OP whose higher standards I recognize. The statement "I paid (X) for this phone and have a right to it being perfect" isn't an unfair claim, maybe be a bit idealistic, but certainly not unfair. But as they say, at least for the time being, "it is what it is."
[Galaxy S II General] B3311:
As you know Barry, I'm on your side - Lord knows, I've thanked enough of your posts.

And while I - grudgingly - admire eallen for his vigilence, his (and others) refusal to even begin to comprehend the fact that these flaws just don't worry some people is irksome.

As I said about 30 pages ago, this thread is a pantomime. I'm still shedding no tears over the nasty rude things I've been called here either.
