So I'm about a month into my SGS2 ownership (from early release date) and I've noticed a problem
When I drag my notification bar down it's possible to see a circle that appears to be burned into the display, it's on the bottom right hand corner of the screen, it's an outline about 1mm thick and about the size of a 5p coin...it's only viewable under monotone greys but its rather annoying - I'm thinking it's due to a chip or antenna underneath becoming too hot and warping the pixels in that area.
I've also noticed the 2g/3g switching is rather aggressive too. Even though i'm in a 3G area it's dropping off every 10-20 seconds, I lose data connection and it has to revert back to 2g or nothing at all, constantly cycling and must be draining the battery a lot too - don't know if its related to the problem mentioned above or not!
Luckily enough, I have logged a call with phones4u - last day of the 28days!! so I can go in store and have it swapped out there and then rather than have to send it off back for repair and be without a phone for 7-14 days!!
Just wanted to make people aware and see if anyone else has had a similar problem.

That's the exact same thing on my new Nexus S.
If you replaced your, did the replacement have the same issue? I'm thinking of returning mine for an exchange but I want to be sure there isn't a consistent hardware problem happening.
I have noticed the same circular discoloration too. Except mine is on the bottom left side of the screen. It is also only visible when displaying greyish colours, such as when the notification bar is pulled down.
Anyway, it is barely noticable during normal use, so I guess not a big deal for me.

A lot of money to pay for such a high-caliber phone to have such a flaw. I notice it on varying monotones. Like when I have a carbon fiber type wallpaper or such as that.

There's really two separate issues that sometimes overlap:
1) The left side banding which appears along with a yellow tint either under certain conditions or, to some, in everyday use. This would seem to be a design issue as, to date, it shows up on every single phone produced.
2) Screen QC issues which include: 1) suction cup circles from production, 2) fingerprints on the inside of the display, 3) dead pixels, 4) vertical or horizontal lines, 5) ghosting, 6) white or black blotches, and 7) wide swings in color temperature.
There's no doubt the QC issues are probably vexing to Samsung. Based on the sheer quantity of displays they need to produce to satisfy demand they're either intentionally allowing displays to go out that shouldn't or are finding out from customers that bad displays got passed QC. Considering the large number of phones sold it's hard to guess the bad:good ratio but it would appear its larger than appropriate. And it doesn't appear to be getting better as newer builds seem to have the same issues as early builds. So banding may be forever but swapping phones may definitely help with the other issues.
I do think that adding the QC issues on top of the banding issue does compound it on some phones. That could certainly explain why some of us are happy and others aren't. There's still a lot of subjectivity at play so it will always be hard to say if what's acceptable to some is unacceptable to others. But with all the phones sold, you'd still think if more than a few percent had serious screen issues there would be a bigger audience for this thread and the issue(s) would have become more prominent on its own. I'd like to think things will get better but production demands may continue to allow QC issues to occur at higher than normal rates. Something that's frustrating for everyone - including Samsung.
Someone said something about the technology being flawed. Here's two links to stories where Apple was/is trying to get SAMOLED for their products. To me, it just helps reinforce that the benefits (color, contrast, viewing angles) still outweigh the downsides (screen life, burn in, inconsistency). And I'm sure Apple's engineers fully reviewed both the upside and downside before considering SAMOLED so it's still kind of a vote of confidence in the technology.

Highlighted in red is the reason for that specific screen defect, some may claim its a minimal issue due to not enough returns out of 6Million phones sold. If an option to get it replaced then please do but expect ANOTHER form of screen defect on the replacement unit may it be yellow banding, extreme color temps or white blotches on a totally black image.

Im not saying you should replace your phone since your entire happy with it and its not a real issue to you but things like this make manufacturers skimp on quality control.
Very informative post.
I would exchange my GS2 if it was new, but then I already have lots of stuff inside. Also, I have rooted my phone already, so I guess my warranty is void.

You could always let the store decide about it, here in my place the software warranty is totally different from the hardware.. I even told the service personel that I flashed a lot of non samsung stuff on my phone and he told me as long as the issue is not software related theres nothing to be void. Of course this varies from region to region.
I went ahead and exchanged my Nexus S and so far I believe I have a perfect one...knock on wood...lol
I had the previous one rooted and using a custom recovery img. I relocked it but made the recovery permanent. This replacement...I rooted it but am leaving the stock recovery img in place. I even relocked it after rooting it. The only difference between this one and a stock phone is this one is rooted.
I was really looking forward to the GS2 on AT&T, but then somebody mentioned screen burn, and I was just curious how susceptible to screen burn it is? Is it something that I would need to worry about?
I've had my SGS2 since may when it first came out. I noticed it last week when using the PlayerPro music app.
The background is on this app is grey which includes where the status bar normally is. I could see where the battery, time, alarm clock icon and signal bars have burnt in.
Then i noticed i can faintly see the home screen app icons when i pull the notification bar down.
So yes.. screen burn is real. Very disappointing. I'd rather have LCD than this amoled that starts to burn in after 4 months. I'm wondering if this'll be covered by the warranty.
Anyone else getting this too?

Did you leave your screen on for long periods of time? Screen burn in is a 'feature' of amoleds, but I think you've gotta try kinda hard to make it happen...

No I don't have the screen on for long. It is set to 15 second time out. I don't use it that much during the day at work. I never watch movies on it or play games. Just calls, text email and net with a few apps.
What brightness level you use?
I have it set too auto brightness. See attached.
Download PlayerPro its free. you might see burn starting on yours too. also show up in google sky map quite clearly.
I took a screen shot to see if it carried the effect over to my pc.. Don't laugh! The iPad burn works like that. It must be a memory related thing. Anyway..thats not the case on the SGS2
Well if you have auto brightness on, wouldn't that mean sometimes your brightness level would be exceedingly high enough to cause a screen burn? I haven't experienced any screen burn yet, even though I tend to have 4-5 hours of display time watching a lot of videos.
My brightness is at 50% and its definitely got some burn in. Very disappointing.

I don't think watching videos will do make noticeable burn. You need static images to create the burn. Download Playerpro, its free in the market, play a song and look at the task bar area and post back.
You mean when the top screen is covered in gray by the app listing the song, instead of showing the notification bar?
Well I downloaded playerpro and played a song (loca people by sak Noel-in case you were wondering ) and there appeared to be some very faint blobs where the status bar icons are. BUT they seemed to fade after a few seconds, maybe my screen is not quite there yet, but it seems to be heading in that direction.
I dread to think what I'd do if there was burn in anywhere other than the status bar. I think I would die.

Good tune! I didn't notice the burn until installed PlayerPro. It doesn't really show in other apps or homescreens. Hopefully it won't get any worse
This issue is pretty well documented with AMOLED, but really, how long do folks keep their devices around here?
I get a new phone at least once a year, sometimes as many as two or three times a year if I decide to sell/trade/upgrade, etc., so even in the event of some small burn-in, it's not something I'm going to obsess about. My phone is a tool, and it does what I need it to do, and when it doesn't, I get another... and I'm not rich, and I do like to take good care of my equipment, but I expect that there's going to be some trade-offs in terms of design... and I suspect that most of us knew about this AMOLED burn-in issue, same as with plasma TVs, though maybe not all.
Yeah but screen burn is going to seriously lower the value of the phone for a trade.
You said it's a pretty well documented issue with AMOLED, but does SAMOLED have the same issue....or is it different?

A year or two I can live with that. But 16 weeks? The phone cost more than than the average plasma TV too!

Thats all good and weel if you can afford it but most people cant and are tied in to 2 year contracts ive had my phone 4 months and the burn in is terrible i took it back to carphone warehouse and they tried to fob me off saying theyd never seen or heard of screen burn on a phone and to ring samsung so now my phones on its way to them to have the screen replaced under warranty
So for anyone suffering from this issue get onto samsung and get it sorted thats what the 2 year warranty is for
So, how did it go with that screen replacement. Did you get it covered under warranty?
I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?
OK, I have seen several threads here, concerning image retention problem, sometimes marked as screen burn. So I thought we could collapse into one general thread on this subject.
So, LCD screen does not have image burn problems. Image burn is name for persistent effect. What we have with our Primes is image retention. This effect is caused becouse liquid crystals in LCD gets used to its certain possition...
For example, if you have some bright background, and you leave it unchanged for about 10-15 minutes, than run some grey screen picture, you will see "ghost" of the background image in the app.
This effect can be seen in many screen technologies. S-IPS and AMOLED are widely used ones on tablets and mobile devices. They both suffer from this effect.
There is actualy big chance you won´t even notice that. Prime turns it screen off after some time, and when you use your device you are probably actually doing something, meaning you are dynamically changing the screen, so image retention has no time to take place.
In everyday use, problems could occur when you use SW keyboard for a long time, or for example game menu controls, etc.
The most important thing is, this is NOT PERSISTENT. Image retention of this type should dissapear after while, you can speed it up by either turning screen off or displaying plain white image for a while.
I believe none of our tablet displays are immune to this. In fact, even glory iPad 1&2 displays are not immune. Neither was my HTC Diamond screen. (Yes, pretty old, but it has nice VGA screen). Sometimes I get navigation cursors retained after reset, even for few minutes (on my HTC Diamond)... So I believe we just need to live with this effect. Most of the time, you won´t even notice it.
But we can share our experience. I have not notice any image retention untill today, when I needed to discharge my Prime more quickly, so I maxed brighteness (IPS+ on) and leave it in home screen on for about 15 minutes. Than I started YouTube app, and on its grey load screen, I clearly seen ghost of my homescreen background. I immediatelly retried lauchning YouTube app, but it was all gone. If curious, or if you want to replicate this, my homescreen image is the default with tree, most yellow-ish like I believe autumn sunset version

Think that is the root of your ghosting issue there, would not call that normal operation at all to leave it maxed out for 15mins. The display is super bright and I dont think even outdoors you need max IPS+ to adequately use the tab.
Well, if I am right, it sould have nothing to do with brighteness level. Like I said, it is different effect, it is not burned. But maye thrucomming light intensity has some effect on the crystal polarisation...
Thanks for the post, I get this effect with my Nexus One as well. The notification bar from having the phone in portrait mode shows itself at times in landscape.

Actually LCD panels can get screen burn, I have had two LCD HDTV s that had it. But those were first gen LCD HDTV s.
You shouldn't see anything like it on LCD screens of today. If what your saying is true then why isn't the status bar in ICS (or honeycomb) ghosting for everyone?
I've done some tests recently after finding this issue on my Galaxy Tab 7.0 Plus. It was VERY dramatic on that tab. Only a few seconds on one screen, change to a screen that is mostly gray and the image persistence was there for quite a while. And it was a strong persistence. Not just a faint image. You could easily read text and see images. The pictures in the following thread show it.
http://forum.xda-developers.com/showthread.php?t=1437445
But after having this issue, I ended up testing some other tabs I have. I've seen the issue on my Kindle Fire's (I have 3 of them). I have a Lenovo Thinkpad Tablet and have not seen the issue there. I also have a Transformer Prime and I do see it faintly on the prime, generally on the right side of the tab when holding in landscape (with power button on top). I also see it sometimes on my 30" Dell IPS monitor.
I guess the point is, it is more common than you think. But some screens may exhibit the problem more than others. That Galaxy Tab 7.0 Plus (that specific one) exhibited it far worse than anything else I've seen.
I've decided not to worry about it. If it's happening to yours and it happens very quickly and doesn't go away quickly, perhaps your display is worse than the norm. But I would expect all of these displays to show some level of image persistence. Return it if it bugs you, but accept the fact that they all may have this issue to some degree.
Thanks to the OP for this post.
There are a few threads out there that have touched on this issue but none as far as I can see that deal with it directly.
The problem comes when you display a pure black screen in low light conditions. It shows that the AMOLED screen is actually grey / blotchy / cloudy instead of being pure black. Initially I thought mine had fingerprints or smudge marks on it, until I realised they were behind the screen. I guess I might have got a phone with a screen that was replaced, but the amount of people who have also reported a similar issue leads me to believe that it might be a manufacturing default? The blotches / clouds on the screen dont change, but exhibit a random formation as one would expect from a defect. It is also possible to see a very faint outline of light running along 3 edges of the screen.
Naturally this is a situation that doesnt reveal itself very often. But I as I use my phone a lot at night, especially reading ebooks or watching films, you start to notice it more and more where you have large expanses of empty black screen.
What I would like to know is how many people have got screens that exhibit this behaviour and how many of you have sent them in for service or had them replaced?
Is it a common issue and something that is to be expected from this type of screen?
You can test if yours has this problem using 'Screen Test' (its free) from the market place. It cycles through solid colours and patterns every time you touch the screen.
Just do it in bed with all the lights out P), give your eyes a few seconds to adjust and see what your screen looks like displaying pure black.
I'm very interested in everyone's experiences and any input or information you have.
Thanks everyone in advance!
ps: I came from a ZTE blade (OLED) which has a uniformly dark grey background when displaying pure black. I kinda expect this as it is a budget phone (albeit with a better than budget screen), but I didnt expect the SGS2 to be quite as bad.
Use "screen adjuster" from the market and set contrast to -60
i have never seen this black low light screen defect. but i am asking you people if any of you have noticed that ugly blurry shadows which are perfectly visible with low light, on white backgrounds especially. they look like marks above the actual display and make high quality images look like low resolution.. it is annoying as hell..
I have this. Noticed it one night when my phone was switched off and charging.
Sent from my GT-I9100 using XDA App
I also have this, noticed the first evening i used the phone...you can notice this during the screen wake delay, or when in a call if you cover then uncover the proximity sensor...don't know if it's a defect but sure it bugs me, i know many won't notice it and will say they don't have this...i will add that if u look carefully to the screen dimmed at lowest brightness in a low light (buy not dark) environment, like early morning, you'll see some "interferences" behind the image, also the darker/yellower left half screen is still visible in these conditions
These things shouldn't be there in a 500€ phone

I did a bit of research and it seems when your phone's brightness is set around 25 - 30% it picks up interference from either the wifi or 3g radio. Notch the brightness either above or below this level and you wont see it anymore.
I agree with you when you say we shouldn't be having these problems on such an expensive phone.
It bugs me too - if it wasnt for this i'd have to say it would be an amazing phone
Might give the Samsung service center a call and see if its something they're aware of and if they are replacing screens with this problem?
