Mine also has it, but it does not bother me. Nothing in this world is perfect.
[Galaxy S II General] Ty_z:
Can someone please answer my question ?
[Galaxy S II General] style34:
Yes for sure. But I heard they will first release an update that makes the screen 3D and 4.5" and after that will fix the yellow tint...
[Galaxy S II General] bcool15:
LMFAOOOOO........
[Galaxy S II General] deanwray:
Jokes aside, it may be possible to either limit or fix the majority to an acceptable level by means of a amended video driver that has hardware plane that produces a negative gradient, however because it's soo varied for ppl, this is very unlikely.

NOTE on the 3D side:

Also, with correct sync, you can make any display that is responsive enough compatible with active shutter technology, actually any refresh rate you could, just wouldn't be very fast/good on a 50hz screen with sluggish pixel transitions :)
[Galaxy S II General] Seabass1:
I agree it's unlikely due to the varying degrees of severity of this problem between phones. My first one was bad, my second one it's barely noticeable, so a fix that worked well for the first would make my current one look bad.

If your phone has a bad screen and you can still get a replacement then do so as there are plenty of ones out there with good screens. Put it this way if my first one was as good as my second and I had never seen this thread I'd most likely be totally unaware of this issue.

[Galaxy S II General] Seabass1:
Fair point. While I don't want to detract from anyone who has had a replacement that still has this problem it is possible to get a good one. Admittedly I've only seen two good screens in person, my current phone which while it has this problem you have to go looking for it and one in my local Carphone Warehouse which didn't seem to have this problem at all. I might be wondering what all the fuss were about if I'd only ever seen these two, but having had one that was bad I can certainly appreciate that there are some dodgy looking examples out there.

The other thing to note here is what someone's definition of good is in this instance. As far as I'm concerned if it isn't noticeable in normal use and there are no other glaring defects then that would be a good screen, others would argue that if this problem exists at all then that is unacceptable.

I suppose ultimately it comes down to a matter of opinion, but I honestly can't believe that my current phone is one of a handful of good ones as if the majority were as bad as my original one I'm fairly sure it would have got a lot more attention than it has.
[Galaxy S II General] BarryH_GEG:
"Perfect" = No banding whatsoever whether on greys at low light or in everyday use.

"Good" = Based on individual expectation, the phone performs well in everyday use.

"Bad" = Obvious screen defects (banding, circles, finger prints, dead pixels, vertical/horizontal stripes) visible by the naked eye to all that see the phone.

So far, to eallan's point, there are no "perfect" phones. To Seabass's point, there have to be a lot more "good" phones then "bad" phones or all hell would have broken loose having nothing to do with this thread.

There are 35,000 posts in the SGS2 General forum. There are 1,100 posts in this thread which has been on the front page almost since the phone was released. That's about 3% of all general posts. As picky as a typical XDA'r is, you're not going to tell me that more people wouldn't have been all over this if they thought it mattered or were personally effected. But since "good" means different things to different people, debating its definition will always be a circuitous conversation. The next big event to watch is the release of a U.S. variant of the phone because it will be modified to meet individual carrier requirements. If Samsung was going to introduce a design or manufacturing change that would appear to be a good time to do it. If those phones still have the banding issue, then my friends, I think what we have is what Samsung intends us to have.
[Galaxy S II General] deanwray:
There is no such thing as a perfect display :) spend 1.5k on an eizo 27inch monitor (professional grade ips), turn the brightness down and you get to see just how the panel is not uniform and consistent.

As for the banding, I don't see display related banding at all, only app colour mode related banding.

But the yellow tint if it's visible on something other than low brightness grey then yeah, thats a return for me, but lucky I don't notice that when at 50%+ brightness in everyday use.
[Galaxy S II General] guitarmafia:
----------------------------
[Galaxy S II General] jvidia:
My major complain is in fact app colour mode related banding (aka gradient banding).

At least this should/can be solved no ?
[Galaxy S II General] pocketAM:
I've got my third SGS 2 .. same issue .. yellow tint on the left side ..

It's incredible ..

Tomorrow i'll try the fourth .. :rolleyes:
[Galaxy S II General] BarryH_GEG:
Unless the phone's you're looking at are significantly worse than the pics people have posted you're wasting your time. All the phone's have it to some degree.
[Galaxy S II General] pocketAM:
No, isn't worse .. is the same .. a yellow strip on the left side, more visible in notification area.
[Galaxy S II General] Lightfunkyone:
jees get over it man! they are all the same.. mine is and I really dont give a damn..turn your brightness up!
[Galaxy S II General] :
A humble opinion - just try to "overlook" the yellow thing. If you feel this is too much of a problem, get a different phone (HTC/Apple). I think this would be the best practical thing you could do now. I don't believe Sammy is going to change their manufacturing process just yet, they are already running low on stock.
[Galaxy S II General] dk206:
Lol
[Galaxy S II General] DrSlump76:
Unfortunately.. i have to quote you. I think that super amoled + screen is not as perfect as we espected.

This evening i will post some pictures of my sgs2. I think that trying to change it now will result always in the same issue, until they will address the problem (i already changed it becouse of a dead pixel, and the past phone had the tint issue too, plus vertical lines).

It's opinion to me that the problem is originated by the amoled weakness to the heat.

Do this test:

when you put your phone in charge (with battery nearly discharged), you will exeperience a warmup of the phone. Put your finger on the right side of the display and then move it slowly from the right to the left. You should notice a temperature raise from right to left.

I'm sure that if i take a thermographic picture of the phone, the high coloured areas will approximately correspond with the faded area of the screen. Additionaly, i think that the problem will be worse in time directly dependent on the quantity of heat generated. The more heat your phone will produce and the sooner organic cells will deteriorate.

So, why phones have the problem the first time i turn it on? I think that all phones are tested before packaging. Testing phone means producing heat, becouse it produce a lot of heat during high mcu use and charging.

I've olso noticed that using a lot the phone (for example web browsing) and letting it warming up, accentuates the faded screen issue.
[Galaxy S II General] rayw:
Hi All,

Just to confirm that I've run all the tests you guys mentioned and not a single difference in the whole screen and I've never notice any changes before...

Hope this help and some of you guys mentioned, if the issue is visible and does effect performance do change it...

[Galaxy S II General] DrSlump76:
Can you post a photo please?
[Galaxy S II General] pocketAM:
+1

I can confirm your opinion.

So the design is wrong .. as iPhone 4 antennagate ..

Today i've notice also color banding ..
[Galaxy S II General] DrSlump76:
Yes, this time we can talk about a FAIL.

About banding: it's opinion to me that samsung engineers uses a 16bit color depth to accellerate graphic rendering despite off graphics quality.

use this code : #*0#* and then select the dimming test: you will notice strong banding, becouse of the color depth used. Using a 32bit depth the dimming would be a lot more softer.

Edit:

16 bit fading:

32bit fading:
[Galaxy S II General] jvidia:
That's exactly it (color banding issue)!

Everytime I play a game and compare it to my colleage's SGS1, I feel very bad about my SII ... I feel cheated !!

I don't understand how Samsung did this and how so few people notices this!

Isn't the SII suposed to have a super image quality ???????

For me this is my top nervous issue on SII.
[Galaxy S II General] deanwray:
You probably mean 24bit colour btw ;)

I did a post on the banding issue and found many mdine profiles, not got round to looking at them yet. And it's not samsung, is the developer that has the choice, heavy filtered phones will look better at 16bit or 565

http://xdaforums.com/showthread.php?t=1121840
[Galaxy S II General] jvidia:
So at least we should have an option to level filtering so we can choose to have better IQ in banding.

edit: moved the rest of my post to the banding thread so I'm not beginning an off-topic ;)
[Galaxy S II General] xiskillo:
I wonder see the very firs perfect screen, please post it pics.
[Galaxy S II General] DrSlump76:
Yes i quote, i would like to see a good display
[Galaxy S II General] Sandruz:
Samsung might do a recall.
[Galaxy S II General] Sp1tfire:
Last time i remember we are not on April the 1st. Do you think Samsung will recall 2 million phones ? Hard to believe.
[Galaxy S II General] style34:
Of course they will not. And since this phone is being sold so well and it is probably the most desired phone at the moment they must be crazy to announce that there is a manufacturing defect that affects every phone.
[Galaxy S II General] pocketAM:
Rumor about SGS II "Plus" arriving in september could be true ...

A silent mode to fix the first wrong project of SGS II without any recall ...

We are Samsung's betatesters ..
[Galaxy S II General] DrSlump76:
I agree: there is a severe engineering problem with this sgs2, and maybe they will address it with a "new" model.

There is a good probability that they will never address this issue, becouse all sgs2 are affected.
[Galaxy S II General] EarlZ:
Lawsuits then ?
[Galaxy S II General] Sandruz:
Of course, and a Class Action also.
[Galaxy S II General] deanwray:
Lawsuit

Have they expressed to you that you cannot take it back and get a refund? Cause without that, it isn't a law suit :)
[Galaxy S II General] jvidia:
Back to topic :D .... does anyone notice that the "yellowish problem" is slowly disapearing? Or it's because I'm becoming used to it or it is less noticeable on my phone.
[Galaxy S II General] EarlZ:
Just to get things straight, those who say they have "perfect" screens or no yellow/banding issues at all post some pictures as an example so that people will believe that there are screens w/o zero issues, as far as I've been following this thread its a technology/manufacturing limitation, which all screens ARE affected to a certain degree.

If you believe your screen is perfect, post images.

Can you post pictures?
[Galaxy S II General] BarryH_GEG:
OK, I'll play along. Those of you talking about a lawsuit better hope you get a judge, jury, or arbiter that's as anal retentive as you are. Since to the majority of people this isn't an issue or one that can only be reproduced under special circumstances, you'd be laughed out of court. And what damages are you suing for? Lack of enjoyment? Let's assume the judge was nuts and ruled against Samsung. At best s/he would order Samsung to allow refunds as there are no punitive damages here. S/he isn't going to be able to force Samsung to make you a perfect screen. So if you end up getting a refund aren't you going to kind of end up where you started?

Picture this: "Your Honor, if you'll have the lights dimmed and look at this background. Oh wait, I forgot to dim the screen. Now if someone will hand me that camera."

I (used to) consider myself picky about my electronics. After following this thread for 50 pages I don't anymore. And geez, it's a friggin phone. Is your time so value-less that you'd rather take on a multi-billion dollar corporation then just return or sell the phone and join the "I'll never buy another Samsung phone" club?

I sympathize with the perfectionists, I really do, but every once in a while this thread takes a truly farcical turn.
[Galaxy S II General] BarryH_GEG:
"Severe?" Really? To who? Obviously not the majority. It's been discussed that because Samsung wanted to claim "thinnest phone" honors they may have excepted a design compromise that allows the banding. They probably have a 1,000 people in R&D and QC with millions of dollars of equipment at their disposal. Do you really think this got by them and that all the Sherlock Holmes in this thread sleuthed it out? So the answer to your question is yes, there's a good probability this will never be addressed.

And it they introduce a new model it will be to make more money not to pacify what amounts to far less than 1% of users who are obsessed with their displays. Go a couple of pages back and read the last online review of this issue. Rather than an "aha!" expose, it begged the rather legitimate question is a problem only creatable under special circumstances really a problem?

Friends read this thread (and both said it was painful) and bought the phone anyway. They're thrilled with their decision. The only purpose of this thread anymore is to let people know about the issue and decide whether it might bother them before purchasing the phone. That and let everyone know if there is a design change so they can get their screens replaced if they want. Everything else is truly just bluster, all of which has been repeated at least a dozen times.
[Galaxy S II General] EarlZ:
@BarryH_GEG

Does your phone have the same issues or is it perfect under your own observation ?
[Galaxy S II General] deanwray:
NO DISPLAY IS PERFECT!... it's just a matter of he find's his acceptable for it's intended use, as do I :) And I'm a CG Artist and budding android dev, so mine must be on the better side of things, I notice if I look, but not in everyday use.
[Galaxy S II General] EarlZ:
You may wish to read what I asked him.
[Galaxy S II General] BarryH_GEG:
I saw this thread floating around on the front page for a long time and never opened it because I thought my phone was fine. At about page 50, I joined the pile-on saying "my screen wasn't effected." When I took a pic of it, I saw the banding. I've posted pics of my particular phone showing apps, the grey background, and the LCD color panel test screens for people to look at. To the naked eye, you can't see anything wrong with my phone in everyday use. I got to see a friends new SGS2 yesterday and it looks just like mine. The big debate really isn't whether the banding is there or not because it obviously is. The question is how does it effect the phone in everyday use. I couldn't see it before I got involved in this thread and still can't see it. A big question though is whether or not there are differences in the issue across multiple phones. This makes it hard to tell whether people are reacting subjectively or the yellow is much more prominent on some phones. Our Italian friend on his fourth exchange said the issue's the same on those phones as it is on pics posted here. So who knows. I definitely tell people I know that are looking at the phone to read this thread because I don't know what their standards and expectations are. And I wouldn't want to force my expectations on them (hint.) ;)
[Galaxy S II General] deanwray:
I know "your own observation" but I cant stand this perception of perfection, there is just acceptable.

I'm going to post some pics of my acceptable screen and see if it would be to others.

BTW: didn't mean to sound, well, mean :)
[Galaxy S II General] BarryH_GEG:
Here are the pics of mine that I already posted. Keep in mind too that in addition to screens being potentially different we're all using different cameras and lighting.
[Galaxy S II General] BarryH_GEG:
More pics...
[Galaxy S II General] diehard2222:
Your last picture looks exactly like my screen does... hmm when the sgs ii plus comes out I will be buying it. this phone I'll give to my brother.
[Galaxy S II General] Sp1tfire:
I dare say my phone looks just the same, i can only notice the slight yellow tint in your last pic and it's not really that bad when meeting all the requirements to see it. Doubt that will bother you in everyday use.
[Galaxy S II General] BarryH_GEG:
To me, the last picture is the most irrelevant. With the naked eye that same shot comes across as a bit of shading on less than 1/4 of the screen. With a camera, a dark room, a grey background, and 10% brightness I can create the issue. Since what I just described is highly unlikely to be a real word situation for me it

really

doesn't bother me. In fact, if there was a fix, I'd probably not send the phone in because someone's whose screen was replaced came back with rattles. That would drive me crazy.

Note: I'm not saying it shouldn't or doesn't bother you or others.
[Galaxy S II General] BarryH_GEG:
OK, let's assume that Samsung sucks and their display standards are totally unacceptable. Pick one of the following:

O2X/G2X

The left shot is an HTC LCD display. I came from a G2X and the one in the pic is actually a better one.

Sensation

The one on the left is a Acer display, the right Sharp. The phone ships with both.

Which would you prefer? A grainy screen with better colors or a crisper screen with washed out colors and a yellow tint? They both have horrible viewing angles and the design allows dust to get under the display.

Atrix

Pentile anyone?

So my perfectionists, there's really nowhere to turn if you want a perfect screen on a dual-core phone. Pick your poison. And the "for the amount I paid I deserve perfection" is getting stale. All the above phones cost about the same and dare say they're not perfect either.

[Galaxy S II General] Jade Eyed Wolf:
Do you have any more pics that show 20% brightness on a grey background (like the pull-down menu?)
[Galaxy S II General] style34:
Barry, you are right about that there is no dual core with perfect screen or bug free phone at this moment. But be honest could that be an excuse for Samsung to make their phones and especially their screens with flaws? So what - we are going to produce defective screens because the rivals make their phones buggy too?

And after all we are talking about the screen. The screen people. The one that Samsung announced as the best screen ever. Super AMOLED PLUS - how impressive sounds that. For me the experience is even worse - of course I do have the yellow tint but after a week a dead pixel appeared on the screen as well. Look at the forum how many are the threads about issues with that supposed to be "the best" screen.
[Galaxy S II General] Erethnor:
Psychological issue? Seriously?

I started this thread so nobody influenced me, and that issue was pretty damn obvious to me without anybody pointing it out.

As has been said already, it seems that the problem exists in various degrees, from annoying to barely noticeable or absolutely obvious. I was in the latter group, while it's clear that some others are in the barely noticeable group.

I could see it on the stock keyboard and I could even see it in the homescreen, so please stop assuming that this problem resides in our heads only.
[Galaxy S II General] Sandruz:
I quote every single word.

This people are very annoying for me...
[Galaxy S II General] Sp1tfire:
I didn't say it's only in your head, don't quote just bits of what i tried to say. I was saying once you are aware of it, you can't ignore it, even though you didn't notice it before someone told you or you started reading this thread (you = all users, not referring to you, Erethnor). Most of the people didn't notice it in everyday use, once they did all the necessary actions to spot it, now they can see it in everyday use too.
[Galaxy S II General] deanwray:
I don't run my phone at 20%, that would be crap on any flat panel display, I have very expensive pro monitors that if I took it down to 20% I would see many artefacts.

So this entire issue only presents if you run the screen at 20%?
[Galaxy S II General] BarryH_GEG:
Be it Samsung, HTC, LG, Motorola, or even Apple, I think that price has a lot to do with compromises they make. We all want and expect more features on each evolution of phone. Yet, I think anything beyond 400GBP/560 Euro will prevent the phone from selling. So I do think that manufacturers are intentionally cutting corners in some areas, accepting compromises, and even taking risks to keep prices at an acceptable level. And to your point, if they're all doing it and people accept it, there's no incentive for one to overachieve and drive their expenses up. Even with its flaws (QC issues like dead pixels aside) I do think its the best display available right now.

Let's assume Samsung came out with a SGS2 "Elite" edition that was assembled by hand and cost twice as much for upgraded components but contained no additional features or functions. To cover the added costs, they'd charge twice as much. I'm guessing people wouldn't buy the "Elite" edition, they'd ***** that the regular SGS2 should achieve the same standard (at half the price). You can't argue features, functions, design, and even quality, without also factoring in price.

Of the four high-end dual-core phones recently released, the SGS2 is still the most solid in both hardware and software. Maybe "good enough" is becoming the new normal? If that's so, perfectionists are going to be in for a bumpy ride.

P.S. - We XDA'rs are by nature not a representative audience. We notice things that 95% of the population would never be aware of or care about even if they knew. That's the group manufacturers target and care about and are always most influenced by.
[Galaxy S II General] Sandruz:
People influence or not the problem exist.

Trouble is that Samsung named the Super Amoled Plus as the

best

screen for a smartphone.

It is the best but there are some problem with a huge amount of that, if mine is worse than your, could I ask at samsung why?

Ok, and if there are 1.9M SGS2 defected and 100K perfect?

Will they solve the problem?
[Galaxy S II General] Sp1tfire:
Your point of view is fine, i said it more than once. Question is are you using the right tool to solve this problem ? I guess not. Obviously thread has made people aware of the problem and that's it. Your choices are:

1. get your money back

2. wait and see if Samsung creates an SII with flawless screen and change it once that is achieved

Do you really think you'll get an official statement from Samsung here on XDA ?
[Galaxy S II General] BarryH_GEG:
Truly, what do you expect? That people that this doesn't bother should convert to your way of thinking and storm Samsung's headquarters with torches and pitchforks? I have never tried to convince those that this bothers that they should think differently. I expect the same in return.

If it bothers you, return or sell the phone, take out ads in newspapers, file class action law suits, or anything else that gives you satisfaction.

The only value this thread has anymore is to inform perspective purchasers of the issue and to keep everyone posted in case there's a design change. Much like politics and religion, no one here is going to be converted to another way of thinking. And since less than 3% of XDA'er in the SGS2 General forum have even looked at this thread, I doubt trying to put together a posse to take down Samsung is going to be very effective.
