Don't worry too much about it. It's just a normal behaviour for any OLED display.

It's caused by frequently used LEDs losing some of it's brightness while LEDs that remain black don't use their brightness immediately. Especially the blue LEDs are affected - this is the most difficult color for OLEDs to accurately display, so they 'shine' at a very high level and therefore lose some of it's brightness quickly.
[Galaxy S II General] iekansh:
I notice blue bar on a white screen. I'm worried. The warranty is covered for one year, right? My whole screen won't go this way or it would?
[Galaxy S II General] Warren.D:
same. i only see it when in test mode. not too bothered about it.
[Galaxy S II General] diggedy:
ive had mine 2 weeks and I can see it. But... ill worry about it when I can see it during normal use
[Galaxy S II General] brittonberkan:
Can you post a picture? This doesn't sound normal....
[Galaxy S II General] Disfected:
Don't see anything on mine, had my phone for two months.
[Galaxy S II General] iekansh:
Not such a good quality. If you look very carefully, you might notice it.
[Galaxy S II General] Nankov:
Did you check with dialing *#0*# and selecting blue? I find it difficult to believe that yours isn't showing anything. I think this is an general issue with all Amoled/Samoled screens, just didnt think a black status bar would cause this.
[Galaxy S II General] Disfected:
Yeah I did the test code thing, but I don't see anything that was mentioned.
[Galaxy S II General] DSF:
Mine is so visible... say in everything that is displayed fullscreen (on medium to low brightness). I've noticed this a few weeks ago. Why they use damn black status bar, if they used other color it may be not so visible.. (i browse web pages a lot, twitter.. and many apps that display white as background). Imagine the new ICS phones with AMOLED in a short period... (who had the stupid idea to implement buttons on display?)
[Galaxy S II General] pacc:
Don't know if I'm lucky, I have the SII white and still no sign of burn-in.

Funny enough checked also on my SI (i9000), and no burn-in also, maybe I just can't see it.
[Galaxy S II General] Igor 3:
Im not seeing anithing but i dont use any blue icons or mods. I read that with blue color its the most easiest to get burn in.
[Galaxy S II General] hofinho:
I had a galaxy s for one year and got this after two weeks already. Now on galaxy s2 it is the same.

But no worries, it doesnt become worse as some of you guys fear. it is also no warranty case since it is normal on every led. Any led tv has these "issues" too if you look carefully at the "border" to black screen that is visible when watching movies in 16:9.
[Galaxy S II General] hofinho:
Edit:i mean it is really hard to spot so no problem at all, dont you think so?
[Galaxy S II General] pacc:
Well, if it's not easily noticeable than maybe it's not a big issue.

I thought "I'm lucky", but I guess it's also happening to me but it's just hard to see.
[Galaxy S II General] MS.:
I must be one of those blind people who can't see a damn thing :-)
[Galaxy S II General] brittonberkan:
okay, after reading through all the posts and combining it with good old facts on OLED here's my explanation:

As you are probably aware after reading this thread, nothing is actually "burnt into" your screens. The fact is just the opposite. Every single one of those LEDs loses some of it's brightness, especially in the beginning of their lifecycle. They'll continue to lose brightness forever, but the process is slowing down and I can assure you it doesn't get much worse than it actually is.

So why is the "screen burn" most visible when displaying blue?

That's because the blue LEDs are the ones which have the hardest work to do: correctly displaying blue in the right intensity seems to be the most difficult thing for our displays. That's why the blue LEDs lose more brightness than the other (red,green) ones. (read that on a techblog some time ago)

But why is the entire area of the status bar slightly blueish when displaying white?

Well, because the status area is usually black and therefore those LEDs have not been used as much as those on the rest of the screen. And given the fact that the blue LEDs degrade faster than the others, it's clear that the area of the screen that's never been used appears a little blueish compared to the area that's been used.

Hope this is understandable, it's late here and I'm a little drunk ;)
[Galaxy S II General] Nankov:
Yes those were my findings too. Hopefully it will even out from time by watching more fullscreen content. And hopefully it doesn't get worse but better. Just think it will be difficult to even out completely as the rest of the screen is still loosing its brightnes even tho slower than when it was brand new.
[Galaxy S II General] sebarkh:
does it mean that the forthcoming IceCream update, that brings the new statusbar colour blue will wear our screens quicker? :)
[Galaxy S II General] Nankov:
Quite possibly..although the new nexus is also with an samoled display and that seems like a bad thing to do when they know the blue leds loose their brightnes quicker. Unless they actualy calculated somehow that it will even out with the rest of the screen and not like ours at the moment where you can see the fresh leds.
[Galaxy S II General] Sichroteph:
And our Tapatalk app has a blue bar just under the status bar ;-)
[Galaxy S II General] hofinho:
yeah but honestly when does anybody use a full white, blue or red screen under normal circumstances (the only possibility to make the so called "burns" visible)? Even when you use a drawing app with full white background or somethin similar you will still have your status bar on top.

My point is that it is really no problem except you are using your phone 24/7 as digital picture frame with just one picture. ;)
[Galaxy S II General] brittonberkan:
for those of you that fear that the effect will get a lot worse over time, here's a picture of the screen of my Omnia II (windows mobile) device that I've used for 2 years before switching to Android.

as you can see, the area around the status bar is also slightly brighter, while you can see some of the icons 'burnt' in. It's not really bad though, and it was never really a problem for me :-)
[Galaxy S II General] PaulParanoia:
You could help the situation by using a launcher which allows you to hide the Status Bar.
[Galaxy S II General] DSF:
PaulParanoia that does 0. How much of the time you spend on homescreen? How about browsing via stock browser? The difference comes from here (many websites are using white background)
[Galaxy S II General] manowar1978@gmail.com:
NORMAL?!?!? Is it normal?!?!? I'm reading right?!

I know the causes of this problem.

All know the cause of the problem.

And this is NOT normal. It is a clear (C L E A R) DEFECT of this technology.

OK, is it normal that I spent over 500 euros for a display with a burn in of navigation bar icons, burn in of my notification bar icons, burn in from google maps? (after only 4 months!!)

OK, is it normal that i spent over 500 euros and I have to worry to hide bar, to reduce brightness, to turn off quickly the screen?

OK, is it normal calculate how much of the time i spend on homescreen?

Is it an ultra modern smartphone? Seems to be back in time.

My biggest concern is that today this burn is still acceptable, but in 3/6 months? :(
[Galaxy S II General] hofinho:
Then go ahaead and talk to somebody from samsung in that tone if the truth hurts you so much i dont get what kind of answer you expect else
[Galaxy S II General] jezza333:
I couldn't notice anything on the blue or green tests but could see some ever so slight [and I mean basically undetectable] shade difference on red where the notification icons are. For all intents and purposes it doesn't exist on my phone. Owned since June.

My SGS1 had this issue on blue after 8 months but it was pretty obvious; during normal usage I couldn't tell, and the burn in was most likely helped by the non-black notification bar.

All-in-all, perfectly happy.
[Galaxy S II General] Sichroteph:
Samsung stock theme integrate a blue bar into programs just under the status bar, wich is pretty stupid.

-will I change my rom for that? Nah. No need to be paranoiac I am sure that even two years after now I will still find my screen astonishing.
[Galaxy S II General] manowar1978@gmail.com:
No, i don't talk with a Samsung center, because this problem is normal. Hehehehe.

I'm just kidding.,

However i can stay with this problem. But nobody can say that this problem is normal.

The only my concern is from other 3 or 4 months. I hope that this display don't aggravate futher.

That's all.
[Galaxy S II General] PaulParanoia:
Just a suggestion dude. I spend a fair amount of time looking at widgets on the home screen. Also use browser, mp3 player, video player etc which allow for hiding the toolbar.

If you're not worried about a little bit of burn in then just stick to the stock apps etc.
[Galaxy S II General] pollanza:
I ressurect this thread because something isn't right about this "burn-in" issue.

I also notice a little difference in my one month old galaxy s2 screen right where there is the status bar.

I've made the color test with *#0*# and:

- The blue is perfectly even through all the screen;

- The green is perfectly even through the scren;

- The red shows a shadow right where the status bar is black.

The problem here is not about the blue subpixels, but about the red ones. It is counter-intuitive because the blue pixel are the one that degrade faster. So I think it isn't a problem of degradation of the screen but it is like the red subpixels, always showing the black color of the taskbar, loose brightness. Maybe it is revertible forcing the red color in that part of the screen through an image, or trying using the phone more on landscape position.
[Galaxy S II General] brittonberkan:
That's an interesting observation (I'm seeing this on my GS2 too, now that you mention it), and one i can't really explain so far...the red subpixels should be off when displaying the status bar... so they shouldn't have degraded...so they should be slightly brighter than the ones on the rest of the screen, not less bright. I'll think about it, have to go to sleep now ;)

Edit: Just wanted to add that i had a quick look at the red subpixels of my Omnia 2 (AMOLED display, same black status bar, WinMo though) and I didn't see a thing there, after 2 years of heavy usage.

Something might really be wrong here, apart from the DEFECT that all AMOLED screens suffer
[Galaxy S II General] obdrz:
just noticed this amoled defect on my s2

- has anyone been successful with getting replacement from samsung for this problem?

- for now I'm trying to use more landscape and

- also what should help is I've set full transparency on status bar (possible in rom control on HyDrOG3N ICS ROM
[Galaxy S II General] bazzag:
I have the same issue so I modified my SystemUI.apk and changed the status bar color to grey. This means that the status bar pixels should also start degrading and eventually will catch up with the rest of the screen, since the degradation slows down with time. I'll post if the screen gets more uniform with time.
[Galaxy S II General] reb73:
Use a non-stock launcher (Go Launcher) where the status bar can be hidden when not in use..

Swyped from my GS2-I9100
[Galaxy S II General] JohnnySM:
I bought mine in september last year, and I don't see any burn in. Does it occurs when heavily using display, or...?
[Galaxy S II General] bazzag:
Try viewing this image in a low-light environment. This is the only color I can see burn-in and even then it's faint so I'm not all that worried.
[Galaxy S II General] DreadPirateDan:
To anyone who cant see it, it becomes crazy obvious when you have brightness at minimum and the room you are in is pitch black (not just under your shirt to hide light btw!).

It's not very different to burn in on plasma tv's. I'd even guess the obviousness of it would lessen if you used the pixel repair apps that are on the market.

Doesn't really bother me personally as it's not noticable unless I seek it out, but I get why people would be peeved about it.

I notice burn in every so often, but seems temporary. I go through a lot of roms so perhaps not long enough to have the same thing on the screen.

I did the screen test and all colours came up clear with no signs of burn in. I have had mine for 5 months. Like I said I do notice that parts of the screen every so often burn in but only temporary for me (like a few mins)

I have checked the ther forums for any repeat problems in this issue. but since there are non, i have to post a new thread.

I done a hard reset on my phone, its spanking new.

but when i want to sync my calender with google calender, i have this error.

maybe the new stock calender is empty, and by sync, it will delete all in my google calender, so it says too many item deleted. what ever option i choose, the problem keeps repeat itself.

SO....i went to google about this, it seems to be a common problem, and the solution is http://www.google.com/support/mobile/bin/answer.py?hl=en&answer=114500&topic=21414

i did that, which is to

go settings>application>manage application>all>calender storage

and clear data.

Now this is the part i'm screwed. look at this.

My calender app is no longer linked to my google account and google calender at all. pressing calender sync will no longer have the error message, but it will not sync to my google account at all.

WHat am i suppose to do? please help. i've google about this and theres no solution.

my phone is rooted by the way, if thats any good news.
[Galaxy S II Q&A, Help & Troubleshooting] Ray1:
HAHAHAHAHA!!!!!

i can't believe it. I actually solved my own problem.

I've been really depress, and never stop google about this. i tried reading about reinstalling the stock calender, but doubt that it would work.

Then i suddenly had an idea, i added my friends gmail acount into "acounts and sync",

once successfully added, i clicked calender sync,

TADA!!! in calender app, the option of my gmail acount and the new gmail acount both appeared!

so i went back to delete the new gmail acount from my phone, and all is back to where it was.

SO proud and happy of myself ^^V

If flashtool can flash stock roms with a locked bootloader, why not the custom ones? I was thinking, what if you could fool the phone into thinking the software is stock when it's really not?

Also, regarding fastboot, if it's possible to remotely access a dongle, shouldn't it be possible to write a script that does the same thing as the dongle itself? I'd be willing to donate and start a bounty for any dev up to the task.

Another thing I thought of is this: if a hole in adb allows us to root, can it not be applied to do other things as well? If you can push system files through adb for themes, I see no reason why installing a recovery would be impossible.

Bear in mind that although I'm not a noob, I'm sure as hell not an expert or developer (though eventually in the future I want to develop) so if there are limitations preventing these things please explain what they are instead of calling me a fool.

Also, on a side note, just how difficult is the script work for Android apps? My previous coding experience is with a game server program called eAthena, if anyone is familiar and can use that for comparison.

[Xperia Play Q&A, Help & Troubleshooting] AndroHero:
Nice ideas :D but i'm now about to disapoint you :( lol

1) The roms we flash with flashtool are signed by sony, if we was to try to flash an u unsigned rom, with a locked bootloader, s1 boot would politely tell us to F-off, flashtool or not ......

2) The dongle you are on about is used in conjunction with setool, afaik the dongle just contains account info but maybe im wrong. Eitherway its setool that does the hard work not the dongle.

3) This is not a new idea, i have had devices beofre where you could use adb/terminal to push a recovery image..... But we have no acess to /boot/ partition while device is booted and thus no way to replace kernel.
[Xperia Play Q&A, Help & Troubleshooting] captain67:
So basically, we need someone to write a program similar to setool, but one that doesn't need credits, in order to unlock fastboot, correct?

Surely someone around here would have the knowledge to do it. Freedom to customize should be available to all, not just people who can buy credits, imo.

Personally, I'm poor and could only get the phone caused I saved money for 2 months and signed a contact. Surely I'm not the only user with a tight wallet.

I say we put up a bounty to encourage the developers around here. I would much rather donate some cash towards the development of a free tool for everyone, as opposed to a single unlock just for myself.

Yeah I knew about them already.. I meant someone else.. Lol

[Xperia Play Q&A, Help & Troubleshooting] Clienterror:
It's not illegal but when a TFT is "Signed" it simply isn't a bit that's turned on or something, it's actually a pretty large encrypted section of code. You'd have to decrypt it which would take freaking forever if at all possible. When I had my Atrix before we got the BL unlocked we tried to decrypt the code (Which was worse than the play probably) and someone figured out how long it would take to manually decrypt it. Something like 120 years running 24/7 on an i7 (I'm not kidding it was mathematically figured to be somewhere around that). If course you could get lucky and get it tomorrow but you'd have better odds winning the lottery and getting struck by lightning on a sunny day at the same time.

If there's one thing I learned from these forums it's saying something is impossible one day,and BAM it's there the next day,no big deal...

So what I'm trying to say is,there is always a workaround,but we need someone to find it...

And by the way,cant the signature just be copied? I mean if hundreds of people downloaded and used the same .ftf file...it doesn't seem unique,or that the phone has something to compare it to...

The short answer is that it's theoretically possible that there could be an exploit, than would allow you to bypass and flash unsigned firmware. However, the fact that you can do it without this (via paid methods) means that it's unlikely anyone would spend so much time investigating.
