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.

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.

The dark grey it is now is useless, I'd turn it black and spare battery and burn in problems...
Hey thats my morph... The text is still white... And it should have the h symbol... It works though.. What are these burn in and battery problems you talk about?
I don't think it was ever proven a black led uses less power than white and my g1 has had a white bar for almost 2 years and no burn in problems...
Sent from my SGH-T959 using XDA App
G1 was LCD pixels were lit regardless of color displayed.
On an AMOLED screen pixels represent black by turning off. Black cannot be burned in and will not use battery. The symbols could still burn in eventually but fortunately the time is always changing as are the signal bars on tmobile
There is plenty of proof floating around from the nexus one (also amoled) saving battery by having a black theme. I'm not gonna dig it up, it's there. They ran multiple tests on identical phones black saved most then red, I think green and blue were mid and of course white is the worst.
So your saying lcd screens don't have burn in? Or that oled is worse? Not meaning to put words in your mouth... I just enjoy a white/light look..
I still think that is a marketing ploy by apple not to buy oled screens..
I think the phone will be obselete by the time it starts to deteriorate...

LCD does have burn in, the difference is on LCD any color can cause it, so on a g1 making the bar black has no benefit.
I'm not trying to tell you what to like, believe me I love android's ability to let us have this choice/conversation.
Clearly google agrees with you on preferring a white look: first the notification bar, then the market, now maps.
I agree deterioration will probably not be an issue for most, as long as you don't set it to stay awake while charging and leave it in a browser window or something all day every day.
Also, what did apple say about oled? I dint know they had a stance on it. I figured they would be going there soon for either phones or laptops
You think there'd be an easy way to do this.. I don't know why but I'm highly turned off by the black bar. Brings back memories of the WinMo nightmare. Lol
I'll send a message to cloverdale and manup... See if one of them went to change the xml so we can have black font in the status bar...

Actually modern LCD displays do not suffer from burn in. I have had an LCD monitor on my windows computer with the exact same taskbar displayed for months and even years, with zero burn in. I have no idea about OLED though.
What's more, even if LCD did suffer burn in, changing the taskbar to black would then cause the taskbar area to not burn in while the rest of the screen did, leading to a situation where you could still see the spot on the screen where the taskbar resided. That's why a lot of plasma TVs and dvd players have the option of putting grey bars on the side of an image that does not fill the screen, with the idea that the grey is closest to what the rest of the display is showing.
The bottom line is I don't think anyone needs to worry about burning in their LCD screen. This is the Vibrant forum, so we should be concerned only about OLED here. So, does anyone have a real answer about burn in on OLED screens? Wikipedia seems to think so http://en.wikipedia.org/wiki/Organic_LED.
So the life is 5 years at 8 hours a day? Half life is about 30 months... Like I said before... We will probably have a new phone by the time out screen starts to be less "vibrant"

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.

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

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.

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

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

I have fallen in love with the Dashclock Widget. If you haven't tried it yet, I'd try it and see if you like it. It's very elegant and informational.
With that said, the widget integrates well with the "Day Dream" function. Basically, you can set it as something of a screensaver to scroll info about your phone throughout the day. I would like to be able to set day dream to "Static", which means I have the white text clock on a black background all day while charging at work. I would also have this set next to my bed as a faux alarm clock.
I have an older 2007 Plasma TV with a burned in ESPN scroll bar because I left the screen on a static image for too long. I would like for that NOT to happen with my new GS4.
Is there any chance of screen burn in with the GS4? I know the AMOLED is a much newer tech than the plasmas of old, but you can never be too sure.
Thanks! :good:
Yes. It will burn over time. It won't be as aggressive as a LCD or plasma screen, but it still burns. You should never leave your screen on with a black background and white text for hours. You should also not be charging it all the time as it appears that you want to. Charging produces heat, heat accelerates the burn. You should only charge the phone when it needs it.

Thanks for the information!
Do you think turning the brightness to minimum would mitigate, or slow down, burn in issues?
There is also a "fade" option on day dream that fades the clock in and out every minute or so and places it on a new part of the screen. I think I'll stick to that for now.
Also, thanks for the charging tips. :good:
It will slow it down. But even with that you are looking at significant screen burn in about 6 to 8 months. Having a low screen brightness with the fade/ movement will be your best option.
