Ok, i own my galaxy about 5 months. I turned the backlight to 0% in andromax, started the xda app and saw my battery, signal indicator and time as a shadow at the brown xda loadscreen. brightness was always set to auto.
I know this effect on plasma tvs, but with amoled, shouldn't be possible by design.
any thoughts are welcome

It's usual degradation of OLEDs. As the statusbar is quite static those pixels that are always light degrade faster than pixels than other ("not so static") pixels.
Now the more degraded pixels are darker on the same voltage levels and this can be seen when the statusbar is hidden.
That's one of the disadvantages of OLEDs currently.

Try rebooting your phone, then in the keypad dial *#0*# and test the screen with the options there check if there is any error in colour reproduction. Or test with images created with paint with only a single colour paint and test it with the screen on galaxy s.
If you observe any colour out of place or not uniform throughout, it might due to hardware issue of the amoled screen.
Hope this helps
checked via sgs tools secret codes (the code from above) lcdtest. degration is there for green and blue, hard to see in red.
will test some disco flash app, maybe it will get better like with plasma panels.
all in all, it is only annoying and the display will get damaged by design. I wonder, if there is a theme for the bar with less contrast grafics, like most tvstation did with there stationsymbol.

The blue pixel organic compound of AMOLED will degrade the quickest. That's the reason these phones are programmed to be more blueish when new, so that as it degrades, the blue should still be visible until the screen dies.
I own my SGS I9000 now since the 25th of June and i don't have that problem, how long is your total amount of Screen on time? I think by intensive use my approx. Screen on time per day is about 2 h. 6 Months are 180 days a 2h are 360h. Industrial Keys for Control Panels with OLED Displays have a average lifetime of 15000h, newer one 30000h.
I don't knew the lifetime for Samsungs AMOLED Screens but i guess it sould be around 10 to 15k hours. So i would contact seller, or samsung service about that.

In the UK you're covered by the Sale of Goods Act - the phone should be expected to last a good 5 years or so. I didn't agree to anything about a failing screen so if it doesn't last an appropriate time then I'll be expecting a replacement screen.

You know what? I went to check my screen under white, red, blue and green; I have some burn in for the battery icon as well. Lol.
To avoid more damage, I will be using the device in varying orientation.

UK law says a product is expected to last 12 months however Samsung do have a 24 month warranty on this product which is nice. If i was you kempas i would have that repaired (screen replacement) as it's completely free except for the time it takes.
Samsung Warranty Information
Just remember to flash back a factory firmware before you send it to a repair centre, custom/modified firmware voids your warranty in any country.
I've got my phone for about 4 months, everyone else I know can see a visible silhouette on the AM/PM symbol with a blue/white image displayed on the screen.
I guess in a year's time its gonna be completely screen burned.. would this mean that SAMOLED is pretty much in infancty/trial stage?

Pretty damn quickly. Well it wont die, but burn-in will set in and the screen brightness will degrade.
Although if you use an app like alarm clock Plus it shouldn't be a problem. When it goes into screensaver mode it keeps the background black and only uses a small portion of the screen to display the time and date. It also moves the time and date around to prevent burn-in.
I use it at night when my phone is charging. The black pixels do emit a tiny amount of light but that shouldn't do any harm.

I've had phone for 6mths. Most of the time on 0% brightness. I never noticed it before but after reading your post I noticed the AM/PM burn in VERY VERY slightly (only on pure blue background)
From now on I'm using 24hrs clock format LOL.
Let's face it though guys, u can't keep a perfect screen forever. I even have a single stuck pixel but I learned to live with it. (1 pixel on a 480x800 screen is fairly unnoticeable, especially if it's a good colour).
It was not noticable till i read about this thread, i hate knowing things like this! hahah
Anyway we can fix the burn in ?
EDIT:
The 24hr format barely helps since theres already a very faint image of the numbers burning in.
Im guessing after a yr of usage the screen burn will be very obvious... with this said im having 2nd thoughts of getting another AMOLED based screen haha
to fix LCD TV's you flush with white. so leave a pure white screen running over night. this kinda resets the crystals.
worth a try with the phone also with the galaxy s you need to have 8 dead pixels to change the screen so if affected area is over 8 pixel should be fine.
Sent from my GT-I9000 using XDA App
The AM/PM sign is displayed by a white pixel so Im not sure displaying a white color overnight can help fix the issue.
Having the screen replaced is not an option here in where I live, its gonna take over 60-75 days for them just to replace the screen and chances are it will be a refurb screen or they will just outright refuse replacement since its a burn in.
The affected area is probably more than 8 pixels.
it resets the crystals so should work. worth a try if someone has a burn

The AM/PM is displayed with a white color by default, so how can displaying a a full white screen fix/reset the image burn ?
btw the image burn is a faint black.
Im also guessing with the GB update they removed the AM/PM so help prevent screen burn and prolong the intitial burn instead of 4 months to probably 8 or 12.
Its been about a month since the launch of the SGS2. I know it may be a bit early but has anyone noticed any image retention or screen burn? I haven't as of yet and I but i do keep my brightness usually on the lowest all the time im at home. Outside its on Auto.
Also even if anyone hasn't how long will it take to happen since I know that all OLed displays including TV's eventually retain images?
I have a Galaxy S. For my phone, It took around 4 months to burn down some pixels after keeping the Screen on for about 3 hours a day. The Status bar was visible on blue background along with screen burn where AM and PM is displayed.
Best Practice is to keep changing the Orientation of the phone frequently and use a Theme with transparent status bar and switch to 24 hour clock to prevent burn in of AM or PM pixels, since they are ON all the time.
Yeah, im trying to do that as much as i can especially changing the orientation with the market and some apps.
So once your pixels gets burned in, can you change them back to normal by putting a different colour over the burned area or is it for good?
I think UK as all the Europe uses 24h clock. So no need to worry about am pm burn in.

"4 MONTHS" any sign of any burn in on my screen and i`ll be looking for a replacement under the warrenty. If this is the case then i`m afraid the Amoled technology is a complete failure in my opinion...!!!
Basically LED displays comprise of 3 LEDs. Red, Blue and Green. When they lit up all together, the form white. Unlike the LCD technology, LED's are diodes which convert electricity into Light and hence they have a lifespan. They gradually start degrading which reduces the amount of light that they emit.
Blue has the highest tendency to degrade faster, hence the AMOLED screens have a Bluish tint to compensate for the same.
Suppose you use a 12 Hour clock and you have AM and PM displayed all the time, as a result of this, the blue pixels that are present at the AM, PM display location degrade, which causes a color imbalance. I.e the other pixels emit more light, but the "Burnt" pixels emit less light. At a later stage when the other 2 LEDs start getting burnt, you can see a patched up section, which represents the burnt pixels, which could be spotted on specific backgrounds.
There is no way to fix screen burn than to get a new display. There is a HUGE topic about screen burn in SGS section. It's worth a read.
I got my galaxy s in August last year and there is a large amount of burn in especially where the clock is.
You can check the individual colours in SGS tools or the xda app when you first open it.

I haven't had any burn-ins whatsoever with my SGS. I had it since October and used it everyday. None. Just checked after reading this thread. None whatsoever.
Koreans are very critical of things they buy. They are one of if not THE country where consumer reports are spread fastest due to their connectivity with the web. Things like this is just NOT accepted over there. And there would be a country outrage especially regarding Samsung products. I highly doubt this is the case. Maybe you have a one off defect.
The Burn-in is caused by the short life of the blue pixel.
I suggest don't make blue pixel lit in the status bar.
I don't know if there has any launchers could make Time and Signal status area displayed in yellow or green rather than white.
My nexus one had status bar burn in within the first month. Still there, no way to reverse it.
But using launcher pro is best solution which hides the status bar completely.
Same here I have had an S1 since it was launched. I used it heavily every day, the screen was on a lot as i used it as an ebook reader. There is zero burn in (checked using screen test).
A friend has one as well, which he bought at the same time as me, he is very critical of every detail, and there is zero burn in on his either.

I`m going to use my SG2 as I want, i`m not going to worry about screen burn in, if it happens which i doubt it,i`ll be demanding a replacement . No one should have to use any programs to hide status bars etc, just to try and prevent it. If it happens then in my opinion its a defect and should be replaced.
Did anybody try for a replacement with the First SG that suffered screen burn...
That's what two year warranties are for I guess. Like post above, I would love to hear of successful replacement for original sgs.

Many people exchanged their nexus one, desire, galaxy s, for a new screen and the burn in just happened again after a month on the replacement. Not much can be done just live with it.
How serious of a burn are we talking about here? A slight shadow or a full on watermark type situation??
Just curious as mine is en route but if this is as bad as some are making out then it will be a deal breaker for me....

Its very very light, barely noticeable unless you look hard for it on white web pages. This is prob why not everyone sees it cause they are looking for something much worse.
I have a slight temporary image retention on my phone, it only lasts a few seconds after using the keypad or the circular lock screen etc , but its pretty noticeable on a dark background
Sure, it fades after a few seconds, but I'm quite concerned that it'll cause lasting damage over time.
I'll try get some snaps, later.. my phone is er, 3 days old
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.
(Picture attached, You have to look quite carefully to see the greyish outlines of the boxes)
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

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...

that does look really bad but the thing is if you are using that in the car and its infront of the sun as well it will get extremely hot...hopefully now that you have took it back they will sort it for you...but using the phone intensively it will get hot...just like computers or laptops even playstation..use them long enough they do start getting hot my friend..all the best hope it wont happen again
Dont these mobile screens have any threshold temperature values to turn off when reaching such temperatures???

Nothing to do with heat, research amoled displays. The more you use a particular color the less bright over time the color pigment will be. Blue lasts the shortest, then green then red.
On my old galaxy s, the clock made a set of "burnt in" pixels in its place. On an all blue screen, the clock had obvious burn in, green screen less noticeable, red not noticeable. One idea could be to lower the brightness to reduce the effect, but it WILL happen to some degree. For me it isn't noticeable unless I look for it...
The ring you see is actually not "burn in" in the sense of old CRTs or plasma, in fact its the opposite. With burn in, if blue "burns in" you always see blue. Amoled is the OPPOSITE. The reason the ring above appears to be redish-green is because the blue is "depleted" more so than red or green. As I said before the colors deplete at different rates, thus blue will burn out sooner than green, green sooner than red. So for the ring you see above, on a screen meant to be 100% white, your "ring" will be maybe 80% blue, 95% green, 100% red based on how much brightness each sub-pixel has lost.

So for the ring you see above, on a screen meant to be 100% white, your "ring" will be maybe 80% blue, 95% green, 100% red based on how much brightness each sub-pixel has lost.

Thank you for this answer. Now, I understand that the screen is "used" and not burnt.
Always using auto brightness.
I can see a difference in the notification bar area when I put the phone in landscape, eg in the browser.
I've got the phone about 3 months and a half ago.. I've pretty used the phone. Using auto brightness.
I noticed over the last few days some burning in. I went to start a thread to see if anyone else had this and there is a thread also underway in the Q&A section http://forum.xda-developers.com/showthread.php?t=1284984
That means any app that stays open (i.e. Car Home) can damage your screen. I had no idea, thanks. At least Car Home has the screen 90% black...
Thank's for the heads up and I will try not to use blue no more. (I did not think it would make a screen "burn out" so fast.) My 5 year old 32in Lcd hdtv I had dimed out to the point were it started becoming hard to see movies with dark themes. (I now have a 46in LED tv)
yep. I have Samsung Omnia II - first Samsung phone with AMOLED display. And noticed that time that blue pixels wear very fast.
It's pretty similar to plasma displays.

Yeah, a little research on AMOLED screens will reveal their struggles with finding blues that last anywhere near as long as green, much less red. Since it's an organic compound in the end, it's going to have a somewhat limited lifespan. How long it'll really last is going to vary by use, brightness, and luck of the draw.
Awww nuts!
That's a bit off-putting really but I'm glad I found out about the screen issue. I'm having a real to-and-fro battle trying to decide which phone to buy, Sensation or GSII. Each have their pros and cons.
when i had my mobile for like 3 days i was playing fruit ninja at highest brightness and all the slashing on the screen after 3-4 min i had a warning that screen temperature is high and it reduced brightness automatiacally but nothing happened to screen
Thanks for sharing this info, RaPiiDe. And thanks to ompuw22c for explaining this amoled specific issue.
Did anyone managed to get screen replaced, does warranty cover it?
My GS is almost 2 years old, but the screen is perfect. I guess that's because I set the screen the lowest bright unless I use it outside. Even though it's lowest bright, the screen is bright enough to do almost everything. I love superamoled.

A respectable night docking app must do two very important things right:
a) must lower brightness to minimum
b) must move the image left/right/top/bottom by a few pixels every so often , to minimize strain on pixels.

Just so no one gets confused here: "Organic" in OLED does not mean "material came from once-living organism, or is a product of decay". It instead means "made from an organic compound" - where "organic compound" is a material that contains carbon. Another example of an organic compound is diamond. Carbon is basically everywhere
I have terrible usage from PowerAMP in car mode. Just got my USB jig though. Will most likely send it in for replacement.

Just got my HK version of the 16GB Wi-Fi only model last week. So far the 7.7 is pretty darn great. One issue I'm noticing though:
For the first few days I was using the Screen Filter app by haxor industry, so I could comfortable use the tablet at night in bed. The app, however, did not properly dim the status bar containing the navigation buttons & notification tray. I changed my dimming app to ScreenDim, which did the trick.
Now however--when dimming is enabled, and holding the tablet in landscape--- I'm noticing that there is discoloring in the exact area where the portrait-oriented status bar is positioned. The tablet looks fine when I'm working within any of the built-in brightness levels.
Anyone else experiencing anything similar?
Had mine now for just over a week. Have not noticed any burn in so far. Will watch out for it..
Many people claim to have seen the burn in effect of AMOLED. I been using my Galaxy S i9000 close to a year now but I do not notice anything. Maybe is my usage pattern. I don't usually spend more than an hour continuously on the screen. I'll pay more attention to the display unit when I drop by the phone shop next time.
If you are worry, you can try the HideBar apk that hide the status bar, but you need root. I tried it and it's working.

I've had mine since the 7th Jan and I have the image burn - the status bar.. Not bothered by it though..

This is likely due to the fact that the notification icons are blue coloured. In OLED displays, blue sub-pixels degrade faster than either red or green due to the fact that they have to be run at higher power levels to produce the same light levels as the red and green.
All OLED screens degrade and suffer burn-in sooner or later; you cannot avoid this.
Personally, I haven't yet experienced the burn-in effect with my unit, but perhaps another solution to delaying this inevitability is to create a modified build.prop which changes the overall blue theme to green instead?
The SAMOLED+ screen on my SGS2 from last May hasn't shown any signs of degradation yet, probably from the green theme of gingerbread.
Just thought I would chime in here. I just recently sold my GS2 which never did what my Galaxy Nexus does. From time to time when I move about through apps or screens I can still see feint remnants from the previous screen. The best example is going from my home screen to the market where my clock widget is still visible for a few seconds. I can turn my screen off and then on or just continue navigating until it disappears. If this is similar to what my Galaxy Nexus does then I believe it's not really an issue at all. (Although I was expecting differently from the Tabs screen since it's a Plus whereas this is not.)

Okay, while I don't have the status bar "burn in" yet, I notice that when using the Screen Filter apps to dim the screen, the lower part of the screen (near the Samsung logo) is dimmer than the rest of the screen no matter when it is view in portrait or landscape. I'm not sure if this is cause by the apps itself or the display panel having unequal brightness. No problem when operating with the device standard lowest brightness.

Yes; this is exactly what I am experiencing. Assuming it's not the dimming applications' doing, I was wondering if Samsung configure the screen like this on purpose...perhaps as a preventative measure thinking the edge by the Samsung logo would have the static image of status bar the majority of the time in daily use.

Yeah Samsung are geniuses. They can produce the screen, but don't know the limitations. You would think they would avoid using blue for cumpulsory static images that you can't turn off. I don't know why they couldn't use red, green, or yellow in that area and avoid any color with blue in it, including white.
Dumb. dumb. dumb.

Agreed. It is quite an oversight.
Having said that, I haven't yet had any burn-in issues with my unit, even with my screen at full brightness just about all the time.
I found a yellowish mark in the same place of status bar when I hide it or change from portrait position to landscape position .. and I can see it only in gray screen like market or settings. I use my tab only for 1 week . Is it burn in? . Dose it go away by itself when I hide the status bar for a long time?
I think it won't go away. Mine got the same yellowwish on the status bar. Actually I love this phone more than any other devices I used to use before but it actually annoy me with this bug screen.

I was going to sell mine and buy another one.. but now I think I will keep it because this screen bug will be in the most of this device
I must be lucky! I've had my device for almost a month now, run my screen at 100%, and I have yet to experience any issues whatsoever! Odd... Not complaining though!
I'm just wondering is there anyways to fix this bug screen? Is that any firmwares can fix it? I think we should complain to Samsung for this burn screen. It is very annoying :-(

This bug is more visable at low brightness
I have mine for over three weeks now and I've no discoloration in the status bar area and I'm using the Tab a lot.

Not all screens are created equally so others may not have burn-ins over 2yrs while others will get it as early as 2 weeks.
Just have it replaced and hope for a better screen.
How much u pay for replacement? Mine can't cuz here no warrenty :-( so sad
