[Galaxy S II General] r_a_c:
This thread is abouth the yellowish/darker 1/3 left side of the screens. Visible on grey background like the pull down menu. However slightly visible on white where the left is a little darker. Or like on the grey keyboard where 2 left letters have another grey than on the right.

Some people would never notice this. I don't think you do either. I don't want to put your attention on it, because you are probably better off not knowing it. You would probably gonna focus on it:D.

But this yellow problem is also on your screen, you can see it on your pictures.

Becasue you didn't say anything abouth it I think you haven't noticed it? And nobody else replied with it, so here you go. You can see it on your pictures.

As for your question abouth the lines. I think some of your pictures where your lines are very visible, are that way because of your camera you took them with; Some of the pictures show it less noticable, more like in real life? Again, many people wouldn't notice, or haven't noticed since they did not used the pull down or other grey in total black room. And I have them too, a long with other people on the forum.

The only question is, is this normal, has every screen this problem and other people just don't notice. Or is there a problem with our screens?

Especially if other users aren't seeing the same defect... No tint on mine, uk version obtained on release..
[Galaxy S II General] kitch9:
Uhmmm, show me a $600 HDTV that doesn't have backlight bleeding or a touch of ghosting somewhere and I'd think you'd have done very well.

The more voltage you put through these types of screen the quicker the pixels switch, with some of them needing more voltage than others as not all will be created equal as is the case with most high performance electronic components. I'd guess they limited voltage a touch for the sake of battery life so maybe some screens perform slightly better than others, but within preset limits...
[Galaxy S II General] icet69:
I think the problem is power supply to each oled. Oleds are current driven, so its important to provide each oled (red green blue) with the same current. If there is a little voltage drop in the imprimted wires from right to left it will result in a less current consumtion of each oled and a lower brightness. If blue is a bit darker than green and red it results in a yellow tint.
[Galaxy S II General] Zebeyo:
I'm not seing this coloration issue on mine.

The below 3 pictures were all taken by a Canon EOS 1000D/Rebel XS at ISO 1600, aperture 4.5, shutter at 1/25 sec.

All three pictures were then ligned up next to each other to copies of themselves to look for the flaw.

The images are taken at ~30%, ~15% and 0% respectively.

The light in the right side comes from my "testroom" (in bed under the duvet) where a bit of light came in from the right side.

I genuinely believe I do not have this issue; however if I'm just not able to spot it feel free to tell me (Since I obviously can't see it anyway it doesn't bother me either way)

The phone was supposedly part of the first batch to reach Denmark. I got it on the 16th of May.

cant post real links due to new user but it's at

The left side is darker than the right side. The yellow tint is less visible than on the other screens.
[Galaxy S II General] sesamee:

I confirm more darker on the left.
[Galaxy S II General] Seade:
Just a thought: what if the problem disappears if you let the screen display a white background for a couple hours on maximum brightness?

Tried it for 10 hours one day. No change.

A facebook page was open. All who have this issue can report HERE:

ww.facebook.com/pages/Samsung-Galaxy-S2-screen-Issue/124708717610574?sk=wall

We could show this page to Samsung.
[Galaxy S II General] Seabass1:
I said it before in this thread but I'll say it again, forget about the yellow tint as that isn't always visible even on the phones that have it, but every photo that's been posted shows the left side being darker. This was pretty much visible all the time on mine.

Based on admittedly very anecdotal evidence it is widespread and most people either don't notice or don't care about the issue. Trouble is no one outside of Samsung really knows just how many are affected, and even they might have no idea.

If it really is present on every single one, and that's a big if, then Samsung really should speak up about the issue. Either way it would be nice if they would at least acknowledge the issue.

SGS2

what about this one?
[Galaxy S II General] MartinNH:
If you compare the upper left part of the grid to the lower right part you can see that it's a bit darker and a little more yellow.
[Galaxy S II General] style34:
I can see the left side is darker than the right one even if i dont open the pictures in full size.
[Galaxy S II General] HD HTC HD:
i think by time, this yellowish will vanish....if u remember, the Iphone also had it one time then vanished,,,,,
[Galaxy S II General] Mustinky:
In real life experience My eyes can't see it darker, i even took alot of time to notice it in a dark room with a 10% brightness, so it's ok for me

besides this is a wonderful phone, flawless in everything, so i can live with it, nothing is perfect even if u paid 500 pounds for it :)
[Galaxy S II General] ArsAequi:
I've attached 2 images, one with display at 0% and one with the display at 100%.

A friend of mine says he sees a yellow glow all over the screen, but I don't see it. Do you?
[Galaxy S II General] MartinNH:
As another user wrote above its actually more of a difference in light intensity than it is a yellow tint. And Your phone is lighter in the lower right corner than in the upper left.
[Galaxy S II General] eallan:
This is exactly correct, and the "gradient" i've been describing all thread. It's a gradient of brightness that's the real problem, yellow seems to be a consequence of it. It's not improving with time.

ALL photos so far have the issue...
[Galaxy S II General] ArsAequi:
OK, well I think I will await the official statement of Samsung (if there will ever be one:p) and then decide if I'm going to return it or not.
[Galaxy S II General] eallan:
Sure would be nice to hear them acknowledge it at least.

I've contacted them through the same channels as others with no luck.
[Galaxy S II General] m0rtiis:
I have the tint too, and if you look in the lower right corner you can see a ring as well. This is a Finland-bought XWKE2/XXKDJ/XXKE2.

Don't know what settings are good for girlfriend's Nikon DX40, so that's about as good a picture as I'll get.
[Galaxy S II General] godutch:
I am really puzzled why everybody is so upset about this yellowish tint you only see with certain colors under certain lighting conditions and no one complains about the heavy banding on gradients so obvious in many games/wallpapers etc.
[Galaxy S II General] eallan:
Your'e puzzled because you don't understand it.

A major major selling point of this phone is the screen.

It's the ONLY way you interface with the device.

Screens have been fine for years.

Gradients can/may be a software issue.

This is a hardware issue.

It's also NOT "certain colors and conditions." There is a noticeable brightness difference in all usage scenarios of the "top of the line phone" with a "top of the line" screen.

It's a defect, and obviously a noticeable one.
[Galaxy S II General] kitch9:
Mountains and molehills spring to mind.
[Galaxy S II General] eallan:
Good for you.

I prefer my expensive devices to be made well.

I'm not samsung shareholder, I don't need to defend them.
[Galaxy S II General] Bratag:
Thats WAY worse than mine. Its very strange that all of the devices seem to have it - but some are far more obvious than others.
[Galaxy S II General] kitch9:
I'd say you're going to spend a lot of your life disappointed.

I've owned numerous "smartphones" all costing plenty of money and as far as issues go in any of them this is so minor it's embarrassing. Pretty much every lcd/led screen I've ever seen has some display flaws somewhere, never mind one that is super bright and is running on milliamps.
[Galaxy S II General] dk206:
Just ignore. I'm one of the first to make a thread on this however after replacement I'm enjoying the phone. Can't see it at all. No vertical lines just a little dark on the left IF you look really really carefully. Moaners get a refund and go buy a new phone or get it changed/replaced like me. Warranty ain't there for nothing.
[Galaxy S II General] julandroid:
The first image is a original screenshot made inside of the phone.

The second one is the interesting one. I took that shot by displaying the original image on my pretty decent IPS monitor and later on I took that picture in the dark.

Congratulations! As you see, now you may consider my monitor as being crap because there is a lot of yellowish, tint spots, vertical lines and so on.

Bottom line: My SAMOLED Plus display looks great and it is much better than my IPS monitor, although they both looks weird on the night pictures, in real life they produce great quality and I can't see any defects unless I over-exaggerate my imagination and start seeing things that are not being there.
[Galaxy S II General] MartinNH:
It's lucky for You to have one where you don't notice the gradient. I had the opportunity to place my S2 next to my girlfriends and the screen on mine is noticeably less light than hers. I think it's unacceptable that a lot of buyers might get second grade screens while others are lucky to get ones that only have slight gradients.. And I think it's perfectly fine to be nitpicking when the screen is one of the S2's strongest sellingpoints.

My old HTC legend had a lot better light distribution on the screen.

I'm gonna drop by the seller to get another unit as soon as they are back in stock.

Appart from the screen the S2 is truly stunning which makes it even more sad to see a flaw every time I look at it.
[Galaxy S II General] zkyevolved:
People, if it is something SMALL, like a BARELY NOTICIBLE difference, buck up! But if you are having major issues, like the screen being REALLY different on one side vs the other, get it exchanged. As said before, the warranty is there for a reason. Regardless of your warranty, the seller gives 7-14-30 days to exchange it from defects. That's a defect. I ordered mine today from Vodafone, it should be here in a few days (starting monday :( boooo), and I"ll check out the screen. One guy had a line going across the screen (from here on the forum) and that's not acceptable. Especially after paying SO MUCH for a phone! :)
[Galaxy S II General] drm111:
So you took a screenshot on your phone, loaded the screen shot onto your monitor, and took a photo of that? Wut?

What in gods name was that supposed to prove?
[Galaxy S II General] mur76:
Yes can u do the same as everyone else. Take screenshot of phone.
[Galaxy S II General] drm111:
But taking a screenshot proves nothing?!?!!?

It's a hardware problem not a software problem, screenshots will appear perfect.
[Galaxy S II General] julandroid:
Many people in this forum, said that they don't experience substantial/visible issue with their SGS II display and the only acceptable prove for them is a picture taken in the dark.

What I'm trying to prove is that you can't make such picture without using extremely well prepared environment (definitely not in a dark) and high quality camera. In my test case scenario I'm using IPS display which I know is very good and produce very accurate colours and great, uniform illumination, but still the photo looks terrible.

So, if you don't see problem with your SGS II then don't insist that every single samoled plus display has that defect (as you can read in the first post in this thread).
[Galaxy S II General] julandroid:
Oh, why is so hard? :)

1. I had to take a perfect picture that has NO defects and where is the right place to take it from? Of course from the build-in screenshot app.

2. Display that perfect picture on my perfect IPS display.

3. Confirm with my own eyes that I don't see any yellowish things or any other kind of defects on the monitor (not on the phone's display).

4. Take a photo of that perfect picture, displayed in the dark on my perfect monitor! Got the idea?

5. Prove with upload of my second photo that even with a perfect (well close to perfect) equipment(monitor) you still can produce a shot, with some strange yellowish spots and weird vertical lines!!

(??!? but why? I use completely different monitor, with different IPS LCD technology? - I guess that is related to the background pattern of the phone's notification area).
[Galaxy S II General] pplcallmeGOD:
Just received my replacement from expansys-usa and it has the same issue, although it's not as bad as on my first unit. Im just gonna ride this phone out for a few months, then rma it when the issue is fixed. Anyone here think this might be a software issue?
[Galaxy S II General] BarryH_GEG:
I think what Julian's emphasizing is that using a camera to take a picture of any display is going to show some anomalies. Although that doesn't explain the left bias that's shown up in the pics that have been posted. Julian, if you want the test scenario to be 1:1, load the website you used for the phone test in your PC browser and take a picture of that. Julian also brings up an interesting point about how well and accurately a camera can capture the detail of a display. And is what it captures a representation of what's perceived by the human eye? Anyone with expertise in that area want to chime in?

P.S. - I know I have a poor track record with you guys. I'm asking this only because I'm curious and not to take away from the original problem.
[Galaxy S II General] Jokesy:
To probably add to what Julian was saying earlier and for some help.

these are captures from my laptop using the test page.

I used my Nokia N8 to snap them.

Pls note that the first image is the original screenshot while others are the ones i snapped
[Galaxy S II General] nunomeneses:
I can't believe this post! Ahahahahaahaha! It just made me laugh like in ROFL
[Galaxy S II General] icet69:
Please come back to the original problem ans stop posting pictures from other devices. Its a serious problem and I had it too. I gave back my S2 and with this threat I want to find out if and when I can get a new one without a problem. The former taken screenshots descibed thr problem well. So it is possible to catch the problem with a cam.
[Galaxy S II General] nocturnne:
I too have the yellow tinging problem. Though another problem I've encountered is picture quality through All Share between my phone and my laptop. Pictures viewed through DLNA to Windows Media Player all have vertical bands running through them that when viewed normally on my laptop do not.

[Galaxy S II General] blade75:
You only proved that maybe your different monitor ALSO has a defect.

Your guessing about the relation with the pattern of notification area is wrong, as you can notice the defect on solid colours like #333333 gray
[Galaxy S II General] Erethnor:
To everyone that went out of his/her way to tell us to get a grip: please drop it, this is clearly not the thread best suited for you.

I created this thread because I could see the problem even on the homescreen - the webpage came later, so that I could have a test case where it would be reliably absolutely obvious.

Some of you are happy with a less than perfect product.

Not me and obviously not a fair few other people, or this problem would've never even hit endgadget and all the other sites otherwise.

I want a flawless smartphone, and I will either RMA my SGS2 till it gets fixed, or buy another phone.

If you decided that your SGS2 is good enough, I don't see why you are implying that we should be happy with it as well. Do you see anybody suggesting you should RMA the phone you are happy about?

Also, I don't see why I should accept a flaw on my phone because your HDTV/LCD monitor/dishwasher display has one as well. My monitors and TVs are absolutely perfect, and I won't settle for anything less than that.

Thank you - I couldn't say it better.
[Galaxy S II General] BarryH_GEG:
You bring up a good point. What are you all going to do in the long term? Using LG and the O2X as an example, Samsung may never officially acknowledge the problem. There was even an online petition started for the O2X and its problems were also covered by the media. Six months later LG's response was "an issue that effected a small number of customers will be addressed with an update." And trust me when I tell you that's a phone in serious need of help.

A Facebook page and a story that's already buried five pages deep on an online phone site doesn't guarantee any kind of response from Samsung. This thread has had 40K views, Samsung's already sold 4MM SGS2s and its about to launch in the U.S. where the real money and volume are. Keep in mind the original Galaxy S had serious GPS issues that effected every unit and Samsung never fully acknowledged the problem. Yet, the phone was an all time best seller and obviously not keeping people away from the SGS2.

Since most of you are out of the exchange period, are you just going to keep your SGS2? I guess you could keep sending it in for repair but if it keeps coming back the same way the problem won't go away and if its like the SGS GPS problem it may never be fully resolved. I ended up dumping the LG phone for the SGS2 because I had little faith that a true solution to its problems would ever be found. The Sensation's had some issues but other than viewing angles there's been little complaint about the display. Maybe that's a better long term choice and you get a qHD screen to boot.
[Galaxy S II General] Sleepycat3:
For a flawless screen, you should have gone with a smartphone equipped with an SLCD or IPS. Amoled is bound to have this type of characteristic because it uses the pixels as the light source. You need a backlit screen if you want uniform lighting.
[Galaxy S II General] zkyevolved:
Yeah...? no. May I direct you here:

It's not even #1 in population! It's #3 (or more). What REALLY mattered to Samsung was to get it out in Asia, which it did, and it made a killing! It's now in Europe (not even all of it yet!) which has almost 3 times the population than the US (http://www.europeword.com/blog/europe/europe-population/ and http://geography.about.com/od/obtainpopulationdata/a/uspopulation.htm). The US will come, but it's not the most desired market out there.
[Galaxy S II General] BarryH_GEG:
Really? Verizon and AT&T have over 100MM customers between them. Name any carrier outside the U.S. that even comes close. They also have 75% of the U.S. corporate market which, from a penetration perspective, is who buys high-end smartphones. Why do you think Samsung prepared the phone for features like enhanced remote security, WebEx and Cisco VPN?

And by all means, keep up the good fight. I really hope you guys emerge victorious but as the examples I indicated show, history isn't on your side.
[Galaxy S II General] MartinNH:
I think you're right about Samsung not issuing an official statement out of fear that it will harm sales more than just being quiet about it. My hope is that they are aware of the problem and that they have fixed it in production. That way those of us who notice the flaw can turn the phone on for a perfect one :-)
[Galaxy S II General] eallan:
Thats ridiculous. My nexus one, Samsung Focus, and Captivate had nothing like this problem. It should not be simply accepted.
[Galaxy S II General] BarryH_GEG:
I think you're spot on. They'll most likely quietly make a change in manufacturing or assembly at some point in the future. The challenge will be to figure out when for those that want to do the swap. There's zero incentive for them to come forward and publicly acknowledge a problem with the phone when the problem goes noticed by the vast majority of users. It would cost them millions simply because people who didn't know they had a problem will suddenly have one and want to exchange the phone.

There's one thing that hasn't been discussed and that is Samsung may have intentionally made comprises in the design in order to make the phone so thin. You have to admit its pretty strange that every screen that's effected is effected in the exact same location. If there's some type of electrical interference at play and Samsung was willing to accept that before finalizing the phone it may never be addressed. They were certainly willing to accept design compromises for the GPS in the SGS.
[Galaxy S II General] aly19:
for the people that have the phone, would one notice this issue unless they looked for it specifically?
[Galaxy S II General] rocketpaul:
Is a defect a defect if its not noticed? Is a sound a sound if its not heard?
[Galaxy S II General] BarryH_GEG:
When I look at the phone with the naked eye, I can't see anything. I even had a monitor tuner in the art department at work look at it and he didn't see anything. It does show up if you take a picture of it.
[Galaxy S II General] MartinNH:
The severity of the problem varies from the unnoticeable to the opposite. Mine is in the wrong end of the spectrum :(

Barry, that's an interesting theory, but what a gamble it would be for Samsung to knowingly send out a phone they knew had problems with the screen. I'm keeping my fingers crossed for a new batch of phones without screen defects.

What I'd really like to know is if all s2's have a slightly darker upper left side.. If that's the case I find it hard to believe that Samsung was unaware when they launched the phone.
[Galaxy S II General] zkyevolved:
China Mobile (ALONE) has "As of March 2011, China Mobile is the world's largest mobile phone operator with over 600 million subscribers.[7]"

It doesn't matter how much of a market they have, European and Asian market ALONE outdo the US market by A LOT. There are almost 3 times as many europeans than americans. Then there are the Asians! Wow! So many! And they all have mobile phones! Which means they pay bills and upgrade phones. Same with Europe.

So having 600 million on ONE carrier in Asia vs 2 carriers having (acording to you) 100 million total, well, there isn't much of a comparison, is there?

I'm not saying the US isn't an important market. It's very important, but it's no where near the MOST important. Samsung is hitting the markets of importance in that order, Asia, Europe, then US?

EDIT: A simple search would answer your questions, use google :).
[Galaxy S II General] eallan:
I've had two SGSIIs.

I noticed it on both of them within 15 minutes of use.
[Galaxy S II General] ithehappy:
So are all the GS II having this problem, or any specific ones? Getting mine soon, embarrassed.
[Galaxy S II General] eallan:
So far we haven't seen a photo of one without it.

People with exchanges have the same issue.

There lots of people that for some reason feel the need to minimize it and say it is invisible.

Several of us would disagree.
[Galaxy S II General] bones45:
I can see this half inch defect at the bottom of the screen at all brightness levels, the camera picks it up a bit better than in person but it's still really noticeable, debating if i should exchange or just return altogether
[Galaxy S II General] jonny_ftm:
To my unit, I tested 3 phones in different showrooms here, in Switzerland. All showed the defect. Seems to be universal until they change their manufacturing, like with GPS in SGS I
