I own both Samsung Captivate and Focus, both devices have SUPER AMOLED screen. Both devices have burn-in problem after months of usage.
Captivate:
I could see the notification bar on top of the screen with the fuzzy clock and battery indicator burn-in to the screen with very pale color especially very noticeable with a white screen! I also saw AT&T stores had these demo units experiencing the exact problem! I then called up Samsung to replace the Super AMOLED screen. Now it's fine but very annoying.
Samsung Focus:
I just got mine in Dec and didn't use a lot on that device. There is a very good reason why WP7 has to hide those status indicators on top to prevent Super AMOLED screen burn-in problem. I also checked out the demo units in AT&T stores, all of the Focus had Windows Phone 7 logo burn-in to the screen at the top left corner due to the static logo constantly playing on the demo mode.
In conclusion:
SUPER AMOLED screen's quality life-time is still short compare to LCDs. Given about 2 months of usage, 8 hours a day with static image such as notification bars for example, burn-in issue is inevitable! In real-life daily usage, give it about 2.6 hrs a day, your screen will be burnt after 6 months.
NEVER USE SUPER AMOLED SCREEN WITH STATIC IMAGE!
On my phone the screen isn't on for very long periods. Even when I am talking on it if near my face the screen is off.
How does this compare to your experience?
Does a phone in demo mode have the screen on constantly?
The only reson OLED isn't so widely used is because of its limited life span (especially on blue color). From what I read in the past, it is very difficult to get blue channel pixels pass 2,000 hours of life span. Not sure if AMOLED or SAMOLED made any advancement in this area. So, the precautions should always be taken. Let your phone screen on 8-hour a day is not a good approach. That's why there is a setting to let phone go into sleep and turn off the display.
My Captivate has been working flawless since August 2010 with zero image retention or burn in.

How many hours per day do you keep your screen turned on? I would give that minimum 480 hrs with static image to experience burn-in. No need to wait 2000 hrs of life-time in Blue Channel in AMOLED.
The life-time of the entire Super AMOLED is here and I'm also being conservative: 480Hrs to start to get burn-in issue using AT&T store demo units as reference.

I use skype and bluetooth headsets alot, so screen shut down may not happen at all until i manually shut off the screen. Moreover, using GPS navigation will definitely cause burn-in problem with static images such as the miles, eta, notification bar, clock, battery indicator, etc.
Android is just not a good OS for Super AMOLED. WP7 on the other hand is for Super AMOLED.
I'd estimate less than 30 minutes total per day (only counts screen on time). So, 480 hrs should let me use my phone for 960 days, or way beyond my tolerance for an *old* phone.
If I'm sitting in a meeting broswing internet or reading news using some apps, almost all of them are full screen and won't necessary have static images on the fixed locations.
Turn the brightness down (I use auto brightness setting) and don't let the screen on for extended period. You will be fine.

I have to agree. The metro color schem (black in most of the screen) is the best way to reduce AMOLED battery usage and lower the potential burn-in risk.

I have both devices and neither or them display image retention. What method or program are you using to test this?
I downloaded a flashlight app on the captivate and on the Focus so I could turn the whole screen white. I also adjusted it to other color,s still see no burned in images.
I've had my Captivate and Focus since day one when they were first released by AT&T.
Go to any AT&T cooperate stores to check out all the burn-in screens. For captivate I use screen test. It cycles from white, black, green, red, blue, and other pallets. I can garauntee you that all Super AMOLED screens are the same given static images and keep the screen turned on such as notification bar, full battery notification, GPS app.
If you don't have any burn-in problems that means you haven't used the screen long enough even you got your devices since launch.

The key here is to keep the screen-on time as short as possible. For normal usage, it will be fine. Will it have burn in 2 or 3 years down the road? Sure, but I probably have to dig it out from the bottom of my drawer to check it out by then. I'd rather enjoy my sharp crispy and colorful SAMOLED for 2 years than worry about burn-in and settle for murky, low contrast and washed out color of the LCD screen for 2 years.
Store demos are the worse case senario.

Very true! But still people really need to beware of their SUPER AMOLED screen. But for gamers...... make sure don't allow a static screen staying on for too long.
Well, I was reading an email yesterday on my focus and noticed that the smiley message icon was like a little ghost in the background. I also noticed the circle/arrow icon. I use orange on black mainly. I moved the tiles around a bit, we'll see if it goes away.

No, it did not go away. It's only visible on white screens, but it is definitely there. I guess I'm going to drop by the at&t store to see if it's a warranty issue, but I highly doubt it. My guess is I'm stuck with it. Since I use the black theme it's not a huge issue, but when I switch to the white theme it looks pretty awful.

Why beware? Image Persistance can happen on any screen that is left running static for long periods of time. In most of the AT&T stores that I have been in the demo units are set to stay up and running for which I can only assume is to attract people. This will cause the image persistance that you are talking about. These phones screens also get used a lot more than your personal cell will.
Use your phone and don't worry about something that may or may not happen. In two years or less you will likely have a new one anyway.
Hilarious!
This reminds me of the times where projector tvs and lately plasma tvs exhibit the same not-suitable-for-gaming problem! LOL
That's one of the reasons I got the Motorola Atrix with its LCD screen!
My previous smartphone was a Nexus One and even though it didn't exhibit ghosting problems, I always tried to use it as little as possible and used the screen on its dimmest setting.
Now I can leave the screen on at full brightness for hours (like for GPS driving for instance) without any remorse!

They have been trying very hard in the past decade or so. The main problem is the blue channel pixels' life span. Most companies have ditched their effort and move to other technologies. That's the main reason why there is no consumer TVs made of the OLED screens other than the $4000 Sony 14" OLED tv.
Unless there is a scientific breakthrough, this situation will remain for years to come.
Has anyone dealt with Samsung Tech support on this issue I just got off the phone with them and they wanted me to do a Hard reset. I tried to explain that this was a physical issue, but they still wanted to follow their script.
Now they have sent me a label to send it off but want me to remove my SD card. It ismy understanding that this card is bonded to the phone and cannot be used in a replacement phone if they send me one. I am going to call them back ut based on my previous conversation I am not holding out hope that anyone there will know what I am talking about.
I don't know if these if happening on all our s2's.
basically, I noticed brightness goes down when displaying a lot of whites. e.g. google vs the whites in a page with more darker areas. (i don't think it's my eyes.)
I've never noticed this on my hd2, or any other phones.
when displaying google's in the browser, the white is not impressive at all.
another test i did was with an image I created (attached), half black half white. open in gallery and slide it so more black shows, or more white shows. The whole screen changes brightness!
My friend's S2 does the same.
can anyone confirm?

Its not.
Its definitely there irrespective of display settings.
Basically even when you are not moving picture, have a look near the border.
There is definite grey banding near the border. It kinda looks like white is bleeding into the black.
And its there on every SGS2, every single one. It can be hardware or software issue.
@OP. you are definitely not alone. I was actually having talk with my friends in UK. 6 of us now have SGS2. 2 are from O2, 3 from P4U and 1 from Handtec and mine is from Clove.
All are experiencing same thing. Its definitely not your eyes.
@others. Its not a glaring issue. You wont notice i t unless there is extreme contrast images on screen like this one. My dad still couldnt notice it when I was showing it to him. But its still there. Will upload video, but its hard to pick on video as well.
It's an option in the Display settings - auto adjust screen brightness after analysing image or something similar.
Samsung thing, I think, since my Omnia 7 with Windows Phone did exactly the same thing. It's trying to save you power and completely normal.

Thanks very much guys, I think I can accept it if it's all built like that. With that option off it really helped! (I feel a lil retarded now). But for some reason that test image I made still has that dimming effect (double tap it in the gallery, this instant change makes it obvious), but maybe that's normal, not fussed. (normal web browsing is perfect)
And no I didn't exchange any phones. Mine does have a dead pixel tho. Can anyone check their screens for dead pixels for me? I know someone had blue lines and stuff on their units, that's a bit drastic. I'm just wondering how many actually have say 1 dead pixel, so I have a better picture before I actually exchange mine or something.
asefsef said:
Yea, I've already got that turned off including power saving mode (mentioned in first post).

Nah, no dead pixels or other screen issues here. If you have dead pixel, i would return it.
Here is the video, its not clear as camera limitations dont really show it properly, but at 720P you can see it for fraction of second, that is not the lens glare but screen turning grey right above the white border.
http://www.youtube.com/watch?v=zGr7xJ1JIjU
around 0:15-0-18 in that video.
As mentioned, its a power saving feature as AMOLED screens don't like whites as they drain power, they prefer blacks. So reducing the brightness helps to save battery.

I can see it grey in the video, almost like that gingerbread scroll limit effect. very hard to see in the video though, would have just said it was the camera.
Yea I'm considering returning. In my other post, I mentioned how Handtec got back to me. In short, not fault since only 1 pixel, but told me I can exchange/return within 7 days. But, they said since it's not a fault, I'll have to pay shipping both ways. (£28 per way, ouch)
Does that sound right??
Just a thought, could not the grey area when moving a black/white border area simply be the screen pixels taking a few milliseconds to go from completely dim, to grey, then to completely white, ie just a response time, albeit a bit slower than what I would have guessed?
On my SGS, going into a completely black app drawer with bright icons and moving around, it also has a very slight dragging effect on some white/black constrasting areas?
SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.
Hey all, I wanted to start a thread to have a discussion about these two things that are my only disappointments in this phone.
Let me start by saying I think this phone is awesome, and yes I feel there are a few other faults on the phone (lockscreen delay when running off the battery due to the CPU taking a second to kick in, weak GPS/wifi signal sometimes, heavy banding on gradients etc) But those are software issues and I know in the near future Samsung/Devs will sort this out.
But I had some big complaints that aren't (still I hope not) software issues. Firstly;
- Response Time.
By this I mean when you buy a new monitor and the response time is listed as 4ms or whatever. This is the time the pixel takes to make a full change. A slow response time will cause ghosting. And that's exactly a issue that the Samsung Galaxy SII faces. Ghosting.
I've gone through 4 replacement SII's for various reasons, and on all of them they ghosted. So it's not just my phone. Samsung bizarrely states the response time is 0.001ms which would be there would be no ghosting at all. However there is, quite a bit actually, by my testing the screen is actually around 6-8ms.
I want to see if anyone else notices it. I know there's been a couple of threads on this but I want to see if the majority of people notice this. Here's how to test, go onto white page with black text on, and then scroll down the page at a moderate pace, not to fast not too slow, try it at different speeds as well just in case you don't get it right.
The easiest way I find to do this is use the inbuilt stock news app, load up any story and it'll give you a long white page with black text you can scroll through. As you may notice if you got a decent set of eyes on you, the text will leave a trail. Also known as ghosting. To me, I find this absolutely unacceptable on such high end device.
- Colour
Also, as it's been widely reported and has been noticeable on all my GSII's, the colour temperature is very 'cool', nowhere near the perfect 6500k. As a result, white's look very blue. This is fine and you hardly notice it on it's own, however when I'm using the device at my PC, which I use on a 32" IPS panel TV I professionally calibrated, the whites on the GSII look more blue than the ocean! Technically this is a software problem and can easily be sorted when custom roms come along but jeez, this is some bad stock colour calibration.
Also when you tilt the display, the viewing angles are generally very good, however tilting the display by pretty much any angle adds an extra blue tint to the screen on an already blueish screen.
I'm an absolutely screen quality perfectionist so these points really get to me. Especially considering this is such a high end device.
Overall I'd give the display a 6.5/10.
After the colour temperature has been sorted, I'll give it a 7.5/10.
If the ghosting can get minimized somehow even slightly through software on top of that, I'd give it an 8.5/10.
Secondly;
- Touch Screen
Now we all know about the movement deadzone/threshold on the touch screen which is massively annoying, but hopefully that'll get fixed in the near future. But What I'm going to complain about is the low sensitivity of the touch screen is the best way I can describe it.
On my HTC Desire, I can tap the screen ridiculously lightly and quick, and the device will register the input, absolutely no questions asked. Absolutely brilliant.
However on the GSII the sensitivity seems to be a lot lower, I can tap the screen lightly and quickly and the screen won't register the touch at all. This is pretty damn annoying as sometimes I just tap the screen lightly normally and I have to retap things. Not very often but still. I wish the device was as sensitive as the HTC Desire.
In it's current state I'd give the touch screen an 8/10.
If the movement deadzone and sensitivity got fixed, it'd be a 10/10.
Now I'm sure I had more to write about but I've forgotten now. I'll edit it into the post if I can think of the other things.
Now as I said, I think the GSII is a smashing phone, sure there are a lot of niggles at the minute, but I know they'll get sorted soon. Just the points I've outlined in this thread are things I'm scared won't get sorted. But you never know, I'm really hoping they can get sorted/do get sorted.
As I said I've had 4 Galaxy S2's all had the above issues, and I've used 2 other S2's from friends who also have these issues, so it's widespread, I'm just curious if people actually notice it.
I've added a poll to the thread regarding these issues. Please don't lie to yourself about this stuff, if you notice it, please answer honestly
I honestly hadnt noticed any of this stuff, i even watched a video of the deadzone and couldnt replicate it myself. I also think the touch response is fine you must have a very light finger/thumb!
The ghosting i hadnt noticed probly because i dont read text as im scrolling i tend to go a page at a time and the fact that im too taken back with the smoothness that pages do scroll.
The blue tint you guessed it i hadnt noticed but then again its not often i hold my phone up to specially tuned monitors.. Then again maybe theres a reason for it maybe it helps reduce glare in sunlight, then again maybe im talking aload of ****e!
no offence but you sound like you could moan for england! chill out and focus on the things it does do well and you may notice the negatives less
Personally....I think your nuts. This is the best screen ever on a phone. I have none of those issues, the touch screen perfectly responsive, my whites are white as white can be. You keep getting your phone from the same supplier and that leads me to be what the problem is. mine is perfect in every way. lucky me I guess

Nah it's just I'm very picky when it comes to screens. And I definitely expect the best on such a high end device, unfortunately the SGSII falls abit short on this.
It's still a great device. Really wish I didn't notice this sort of stuff haha.

Best screen on a phone possibly. It's not the best screen ever though, it's good don't get me wrong, but not the best.
And I assure you, your device has everything that I outlined in my original post, it's just down to the user if they notice it or not. When I used my friends Galaxy SII's (who both got it from different places to me and each other) I asked them about this stuff and they had no idea what I was on about, so I thought my phone was faulty and I had a look at their GSII's and theirs have the same problems aswell, they just don't notice them. (They did after I pointed it out though muwhahah)
I must not have a sgs2. Maybe its because mine is from first batch but I have none of your listed issues. After 4 devices, it cant be samsungs fault.
Heh, guys every SGSII have these issues, I'm not arguing that, was merely checking to see how many people notice these issues (not many in the grand scheme of things apparently) there's quite a lot of reports of these problems so it's just down to the user

I guess I have horrible standards. No shadowning on my phone.
The ghosting and blue-ish colortemperature I noticed right from the start. But to be honest: I really dont care. At least the ghosting is nothing which stands out of the crowd... all of them have it ... HTC, LG, Apple. The only reason you don't notice it as much, is the lower contrast on the other displays.
As for the sensitivity: It's a little lower than with my htc hd2, BUT I'm actually glad it is. The sensitivity on the HTC phones is ridiculously high. You don't even have to touch the screen and you end up clicking something, which can be quite annoying sometimes. On the SGS2 I never had any missclicks, nor did I have any non-responsivenesses. Perfect setup for my taste.
I think all of the average joe out there probably doesn't care about all this minor issues. You must have the intention to find the fault of the phone in order to get what you want to find but do you think most of us would be doing this? Haha.. Tbh I don't really care as long as the phone does what I want without falling apart. lol..
Yeah I was a bit surprised by the ghosting, having seen the response time claims, but neither that nor the colour temp (on 'movie') have really bothered me so far.
What has irked me a bit is the image sharpness. On a site like m.engadget.com the coloured text on white background has a dark outline all around it, which to me looks horrible. Anyone else noticed that?
I think the ghosting issue is due to the low fresh rate of the touch screen.It's lower than 60HZ.
When you scroll the screen,the animation is not smooth enough,so you see the ghosting.
It's more of a visual persistence issue.
I remember when some choppy animation showed in CRT,I can see ghosting.
Never the less,when your finger leave the touch screen,let it scrolling itself,you can see the "ghosting" would be less noticible.
But you can still see it,that's because of 60HZ refresh rate of the Display.
I just wondering if there is any way to change the fresh rate of the touch screen.
What are you doing that's causing ghosting issues? There is a definite color temp issue but that's how every amoled screen has been so far. I would take a little bit of blue tint over the black color performance
The thing that causes the ghosting, as I said in my original post, it fast movement. The screens pixels can't change fast enough so things leave a trail.
As I said the best way so see this is to loadup a long page with a white background and black text and then scroll down at a moderate pace, fast but not so fast you eyes your eyes canty follow the line of text. If toy do it right and you've got a decent set of eyes you'll see that the text leaves a trail.

Yep, there's a lot disappointments with the screen on this phone. However as the poll is so far proving, majority of people don't care for quality as much as us. Only a few others care/notice about the things we're complaining about.

Thanks .. Thats the funniest **** i have read all day...
Theres nothing wrong with my sgs2 and ive owned Hero's Desire's Nexus One's and even an LG2X.. This phone is superb.. This dude does sound a bit anal..
Hey. I can definately notice ghosting on this screen if i purposely try to but as others have said, it doesn't bother me in the slightest. When watching films or playing games it's non-existant.
As for the whites, you yourself stated you can't really notice until you hold the device against your professionally calibrated screen. How are the blacks in comparison? Out of interest, how much was that screen/calibration.
I think the main problem with alot of peoples gripes is focusing on only the weaker aspects of the phone rather than the device as a whole. People want perfection which unfortunately doesn't exist in the world of electrical consumer tech.
now i see this horrible grey everywhere i cannot even look at my phone any more!
I hope that this issue would be enough to change my device!
Hey drm111, as you know I have those problems too.
Did you have them on all your 4phones?
1) As you know I have this topic in wich one screen had this blue ish coat on the screen, noticable from the angles you talk abouth. But the other one does not have it.
So maybe not everyone has that blue coating? Did you investigated that further?
2) As you also know there is this yellowish/darker 1/3 of the left screen, probably some don't notice it. You have to be in a dark room or in a light one really looking for it. You read abouth this huh?
But I you didn't post it here. Aren't you having this problem? And did you have it on al of your 4 phones?
3) Ghosting, yes i notice it to. No sharp text when scrolling,is that the ghosting too?
I have this first generation ipod touch, text stays sharp when scrolling. Should be the case here too.
4) Than you have the grey tints, wich turn pink. You can see it in the topic of nongrata23. But some phone don't have it it seems. Software or hardware?
We need to figure out what is 'normal' and what isn't. As I don't want to send my phone back if it is normal at this point for all the gs2 that are on the market.
Let me start by saying i used to work for a PC magazine and was among those who blew the whistle on the nVidia texture replacement fiasco surrounding the Geforce 5800. I can see a single texture out of place in a high FPS game, so my eye is VERY keen.
The colour of the SGS2 is slightly blue yes, but mine is no worse than the average LCD, including the Retina display.
Response time is seemingly slower than the previous AMOLED screens ive seen, but again is more than a match for the LCDs out there.
I would say samsung have made a trade off between the sub pixel density and other factors. It works for me just fine.
The 16bit thing is interesting. It looks to me like the screen isnt 16bit, but it is using 16bit at times. Thats a driver issue.
Ive had this powerhouse of a phone for just under 16 Hours, Screen has only been used for around half an hour etc,
Ive just noticed some screenburn on the screen The four buttons - (Phone, Contacts, Messaging, Apps) are visible on the screen when I look at a grey-ish background (Such as the speedx initial bg). Ive been through 6 Galaxy S2s, Three of them had this issue - Is it me, or is this a bit weird? Phone screen on for only 30mins since it was factory shiny&new, and theres already light screenburn.
Is this a characteristic of SAMOLED Plus, or is this a faultly batch? (Im on my 5th replacement phone from Amazon due to various faults). It seems a bit weird, a phone thats cost near £475 inc has this kind of issue.
Thanks In Advance,
Aman.

It doesn't look screen burn as it looks coloured. it might be the app you are running has transparency.
afaik, OLED does suffer from screen burn like plasmas do - potentially, but not that quick!
Well, it can happen. After a month i started seeing the same thing when pulling down the notification bar. So it's not app related, cause i don't use other launcher, i can clearly see the shadow of the 4 icons for a few seconds when pulling down the notification bar. They disappear pretty quickly, i'm not that bothered about that.
Also notice even if you just got the phone the very first second the digital clock actually burns through the notification tray and slowly disappears, I think its a technology limitation on the SAMOLED+
hi i dont know if my post will help or not
put i have a samilliar proplem with my sgs2 screen
i have proplems with colors like grey and dark blue
i will attack photos for u to see if u have the same proplem with colors like me
and my phone is only 14 day old
i really dont know if the colors are normal or not
p.s: make ur display 60/100 to see the colors
on my sgs1 the screen was way better
the first two pics are of the grey color ( to see if u have the same like this pic open msg and write a messege there is an option to write sound messege click on it
it will show the same thing see if u have the same like me
and the third pic is of the home screen to compare see if there is something wrong with ur screen
also could some one please look at his device and my pictures so i can now if there is something wrong with my device
thanks alot in advance

Seems like a SAMOLED+ limitation as you say. I was just curious, it shouldnt bother me much whilst im using my phone normally.

If the screenburn gets really bad, I suppose i can always just use the 2yr Warranty I have on the phone to get the screen replaced. Waste of an invisibleshield though.
Considering the phone is less than a day old, the screen might go really weird in 2-3 months - Which is what im worried about.

I would have to agree that the S1 screen is was a better display even if did have a more jagged edges on the fonts.
I have a similar issue in the messaging app, but with the keyboard. If I 'enable'(/turn on/whatever) it then disable it, it's 'shadow' stays there for a couple of seconds. It is however not a permanent burn in, so I think it's just the screen's limitation and it doesn't really bother me as this screen is still by far the best I've ever used.

wouldn't that screw up video playback though? sounds more like a software bug
I turned the clock on the notification bar back to 24hr , as i read/saw the AM/PM can burn in as they are displayed a lot longer then the 24hr digits which move at least every hour.
I just discovered this issue last night. I had been noticing a few lines here and there on my regular usage and I thought it was just a defective screen. Through the use of Terminal's blue screen, I realized that it wasn't defective.
I have a car dock, and use PowerAMP in the car every day. As you can see above, those burn ins are the buttons in PowerAMP. I went to take a picture of my SGS2 with my N1, and while looking at the blue screen on my SGS2 through the display of the N1, I noticed the N1 had the issue too!
I'm trying to run JScreenFix now to see if it solves the problem, but I highly doubt it.
Will Samsung even honour the warranty for things like this?
I have an SGS1 of 1 year old and my SGS 2 bought in may. Side by side, I will never exchange my SGS2 for another SGS1. Screen quality (colours and details) is by far better on SGS2. No comparision
I also don't see any burn in in both devices (keybord test, status bar...). Maybe some defective devices around that you just should exchange
If you want to test your screen or anything on your phone type *#0*# into the keypad
If the burn don't show up on green blue or red then its something else
I also have the same issue. I can see shadow of the System task bar. It was quite vivid on RED and it shows as lighter blue on blue colour. And on white it became pale white. Bright yellow as well on yellow.
I've tried various things like put the screen on full brightness on Black and Red and blue but still have the shadow there.
I will see if i can get my warranty repair.
I just wanted to confirm that the SGS2 sure can have a Burn In, as it was declared before as "Burn In Proof".
I noticed it while playing the recently released Game "Osmos HD". The game's color temperature is pretty blue-dark, and thats where I can see a slight burn in of the Task Bar.
Afterwards I checked my screen with various LCD Test programs and BAM - with low brightness I see slight burn in of the whole task bar. I can even see the signal indicator, the battery percentage and the spot where the clock sits.
But its only visible at very low brightness and a blue-purple coloring.
I called my brother, who has the Galaxy S2 as well, and he directly went and checked with LCD Tester as well. He, too, reported to me that he also has a slight screen burn in of the task bar, tho its very tough to spot. I guess, if you dont know its there, u wont notice it.
We both have our SGS2 models now for roughly a year, and the screens already seem to decrease in quality and stability.
I am a fan of Super AMOLED+ color quality and contrasts, but my 2 bothers and me have all the yellow tint issue, tho its not very drastic, and all devices start to get kind of a permanent screen burn in.
Its really sad to see that the otherwise fabulous screens already show its age. I hoped that Samsung learned from the SGS1's issues and user feedback, but sadly, it seems like they kind of ignored the fact that the Super AMOLED cant take much action...
My girlfriends Desire HD's screen (which was my phone before I got the SGS2) is still showing good colors. Sometimes I think about getting an LCD device again...
I think what most posters in this thread are reporting is Samoled ghosting, ie image retention for a few secs. Its not permanent, unlike burn-in, which some people may experience after some months of usage.

No, its not ghosting at all.
The taskbar image thats burned in is from MIUI. And since I am running either and Sammy ICS Build or Androidmeda for a while now, this image must've been there for longer than I thought.
As I said, I just noticed it yesterday while trying out the Osmos HD Demo. And its clearly the MIUI taskbar. Must be there for more than a couple of days already.
No screen burn on my Galaxy S2! Btw, been comparing screen to iphone 4/4s and Galaxy S2 screen way better! You have to have some sort of "telescopic" vision to notice resolution advantige on 4s... Who anyway reads webpages fully zoomed out? LoL... With magnifyng glass?? Contrast and colors advantige is huge on galaxy side....

I dunno why u are now comparing with the iPhone 4/4s here, but thanks ;-)
For how long are you using ur Galaxy S2 now? Mine is running non-stop since a roughly a year now.
And yes, it seems like a permanent screen burn in on my end. Just checked again, same visibility of the probably weeks-old MIUI taskbar.
I have my Galaxy Note for 10 weeks and after using it always with 100% brightness there are aging effects.
Specially at blue backgrounds, but also at white and gray I can see the home screen icons, the clock and some buttons from jelly defense (I played jelly defense 3 weeks daily 2 hours) shining darker. (you can see it on the photo)
Now my Galaxy Note is in service for screen changing.
But what can I do in the future to avoid this aging effects? 80% brightness, 90% brightness?
Samsung didn't know this problems (I'll not believe it).
Has anyone practical experience with this problem?
Typically Blue pixels age the fastest. So pick a warm/red background. Avoid 100% brightness. Use auto if possible. Avoid leave screen on for prolonged period. Avoid static text or icon on the screen for too long. Basically the same care you would do to a Plasma TV except even the plasma TV screen(around 80,000 to 100,000 hrs) lasts 10 times longer than the AMOLED screen (estimated around 10,000 to 20,000 hrs).
Looks like you've discovered amoleds dirty little secret. I avoid pixel burnout by using launchers that auto hide the notification bar as well as browsers that allow you to hide the navigation bar such as opera. Opera let's you browse in fill screen mode.
I often refrain from using apps that show static images for long periods of time. I try to use the browser for everything that can be done through the regular Web portal of a site.
There is no way of getting around static images in apps unless the Dev accounts for it. Some devs are aware of amoled burn out and have options to hide navigation bars.
Ultimately you have to be mindful of static images and make sure to either avoid them on your screen for prolonged periods of time or remember to rotate your screen.
This is why I'm not looking forward to virtual buttons on ICS. It will destroy amoled screens for sure. Hopefully Samsung will retain physical button(s)
10 weeks is a pretty short life time, My friend's Nexus One (1yr++) does not have the very slightest hint of screen aging why my the galaxy S2 that I used for just 2 months already had the AM/PM burned in.
Its normal for OLED screens to age but it should not be this fast, this is probably why apple is not looking into OLED screens as the quality and or lifespan could be problematic.
There are some manufacturing defects. Some screens are just fade faster than others. But in general, if you know how to take good care of your screen, it will last a long time. My old Galaxy S lasted over a year without any noticeable burn-in. My new Galaxy S2 has been 4 months w/o any problem.

like the part where you say "noticeable"
no matter how much you try to take care of it. It will happen. Its already there. (Depends to which degree)
My advice apart those ones about hiding the element that are always present.
Do not look for a screen burn in. Or do not look at the ****ty quality of the AMOLED. When you would look on for example on grey/ brown background easiest to spot when going to the marker you would notice the differences between the different parts of the screen. Its not perfectly even from the time its build. The color is displayed in different shades usually presenting itself in "lines".
Had my Note for 1 hour and I noticed it. Brand new.
But then again I know what to look for (proud owner of Galaxy S) and where to look for it.
I bought this device for the resolution and power. Not for the screen build quality
When I say 'noticeable', I meant to use screen test patterns. Last time I did that with my Galaxy S, I don't see any burn in with the test patterns at all. But I agree one should not purposfully sort after the burn in. It will always be there. But I also don't need live in panic. The great contrast of the screen (or infinite black) outweights any shortcomings it has. Side by side with an iPhone 4/4s, I simply can't stand the foggy looking screen of the LCD on iPhones. Every iPhone owners I encounter liked my SAMOLE screen better.

Hello fellow Galaxy S owner, This is the phone that brought up my standards and expectation for a SAMOLED device. I never saw any lines/uneven screen brightness and other garbage on my Galaxy S, even on greys. So this has brought up my expectation for a very high level which was crushed by the Galaxy Note's screen.

Good for you, I bought the device as a while package with the top concern about screen build quality and as an HD playback device which it does not meet the purpose
Just a quick tip I picked up from someone else on this site (I forget now who it was, sorry). Change your clock from 12 to 24 hour every now and then (and visa versa), it shifts all the icons along a little
This is both an interesting and depressing post to find. I was so excited to order my International Note soon, but now I'm super paranoid about screen aging. I've read so much conflicting information about it online, I don't even know what to believe anymore.

In terms of lifespan, LCDs still trump amoleds. That's a fact you'll have to live with.
No screen technology is perfect. SAMOLED for the moment has the problem that pixels decrease in brightness with ussage. So try to minimize the amount of light you get off the screen. That will also give you more battery life.
Try to use black backgrounds, and white text on black background if the application allows it. Of course if you spend 3 hours a day on a game with static icons and menus, that will wear some pixels more than others and you'll end up with something like the OP.
If you go looking for small variations of color, you're going to find them. But the superior brightness and contrast of a SAMOLED screen wins me over. Even when I know its effemeral and will degrade with time. But anyway, who keeps a phone more than 2 years?
Yeah, but I just found this information for the first time today, which is why I'm so depressed. I'm a digital artist so having a nice little on-the-go sketchpad has me super excited, but also worried because of the screen. Expansys tells me there's a 2 year warranty, but I don't know how that would work on an international phone if the screen goes bad...
---------- Post added at 02:46 PM ---------- Previous post was at 02:45 PM ----------
vcespon : Yeah, I normally keep the brightness on my Atrix down quite low anyways. The max brightness setting is *blindingly* bright. As for the 'who keeps a phone more then 2 years", I had my iphone 3gs for quite awhile thank you very much. That and if I spend 600-700 bucks on this baby I want it to last! If I get at the very least a year to a year and a half out of the screen I'll be somewhat happy, though closer to 2 would be better obviously. I wonder what the long-term outlook is for the life of these screens anyways. Does anyone know the mean-time-before-failure for them?
I would also try using black backgrounds or dark themes on as many apps as possible also. Like tapatalk or k9 for instance.

I think there are some references how long the pixels "live". You should google. Even though Samsung said that they used new materials to build the displays.
I can tell you one thing you get used to the inferior screen in time.(Few rants not and then) So I wouldn't worry about that. If it really fails you. Meaning someone else will notice something wrong on the screen no just you. Claim warranty
Also to pointing out. There is shor-term memory effect as well. I think I already posted some bad quality pics here about that from my SGS. > http://goo.gl/URYzm I do not remember if this is a burn it or just the memory effect. I think its the memory bla bla. Second pic is best.
Thanks for the information! I think I remembered someone saying that the short-term memory effect gets better over time as well. I'm mostly worried about the screen quality as I plan on doing a lot of sketching on it, which kind of sucks because it'll most likely be using a light-colored background then. :\ I wonder if the AT&T version will have the exact same screens or if they'll be a slightly updated version. I guess not considering AMOLED is still AMOLED.

You worry too much. And you do not even have that phone yet.
First of all not sure how its in your country, but here you can return in if you dont like it in a week I think.
Also if it becomes really apparent you really can go to a service center. I do not remember someone saying that samsung refused to change the screen.
Also I was ranting here already a year ago about the Galaxy S. I hate SAMOLED soo much since I got the SGS (18 months ago). I own an iPhone 4 and love retina and SLCD. And yet bought the Galaxy Note as well (despite the fact I knew how faulty it will be and how I will hate it )
Hey, I'm paranoid! I *really* get upset when I get a device that either isn't stable or has something wrong or defective about it. (Especially something that costs this much!) I'm in the US and am debating ordering through Expansys (USA), and I've heard they have I believe it was a 2 year warranty, but I have a feeling I'd have to send it to Expansys and have them take care of it if something went wrong. I can't see Samsung handling an international phone's repair in the US?
Aren't we strange with how we buy our gadgets? We know we will hate something and yet still buy it.

Here you can see my homescreen. There is already white text on black background.
But I can see the shadows of the big clock and all icons. The shadows are the white parts of the homescreen; for example the "S" of my S-Banking-App is very visible as a black shadow in all other apps with lighter background (Internet-Browser, ebook-Reader etc..).
And the homescreen is visible only for a few minutes, because when I want to use an app I directly start the app. I don't look so much time to the homescreen and my Galaxy Note goes after one minute in standby mode.
That means only 10 minutes/day homescreen with 100% brightness is enough to damage the screen visible after 10 weeks?
Okay, playing Jelly Defense 2 hours a day at 100% brightness is not so good, but the problem is not the time, because a few minutes looking to the homescreen has nearly the same aging effect.
