Anyone else have issues with screen burn in?
I am having some. On the right hand side the bottom bar has burned into the screen creating a permanent shadow of the bottom bar from when I was using the tablet vertically It is extremely noticeable on dark grey backgrounds.
Anyone else have this happen?
This is grounds for a return yes?
IMO this is unacceptable.
IPS displays can suffer from image persistance. It's quite well documented. You can either run a color strobe or display a white screen for a while to try to release the electric charge built up in and around those pixels.

So this is normal?
I have not heard about burn in on tablets...

It's not burn-in in the traditional sense...it's usually solvable by the above methods...whereas old-school burn-in on crt tubes was permenant due to the technology.
Ill have to do some research on this. Any suggested articles on this particular topic?
Or advice on how to prevent it like optimal screen time usage etc?

I got my hands on a Razr x910 and it has screen burn. what are my solutions for this? Can i order a screen from someplace on the web ? what are my options?
please post a picture, i ve never seen a problem like this in a so short amount of time
Do you mean like black dots when the the screen is black?
I thought only plasma screens have burn marks
There are a couple apps that can attempt to reverse it, like Display Tester, fixes the burn by scrubbing the pixels with white and black nars, try it, couldnt hurt

here is a picture of the burnt screen. its a yellowish tinge in the screen. whenever there is a white or light screen you can usually see them. However it doesnt effect games/videos, so its not to bad..
I ran that display tester and no luck!
I'm not even absolutely certain that's screen burn. AMOLED is kind of notorious for... inconsistent... colors (especially whites). And the RAZR in particular has some artifacts that are especially visible in the dark. They don't impair usage generally. But then the display I'm on typing at the moment isn't the best so it's hard for me to be sure how bad it is on your screen.
EDIT: scratch that, looked closer and I can make out the launcher icons at the bottom. That kind of sucks, actually.
its not to bad, and again only on light screens. I am always going to run a dark background so its unnoticeable. But when i run into some extra money ill just buy a new screen This place http://www.repairsuniverse.com/motorola-razr-lcd-screen-replacement.html
seems legit for a not bad price.
Might want to turn down your screen-on time as well. The only other RAZR I've seen like that was the demo unit at the Verizon store & its screen is on all the time.

Whiskey Tango Foxtrot... I've never heard of this on a mobile device, a tablet, or a laptop. Although cheaper LCD TVs (like my POS Westinghouse) can have it happen. An impractical solution would simply be to leave it off for a few days. But, that's not going to happen with a phone. If you can find a video of static... like a TV screen on a channel with no signal... and can have it run in a repeating loop, leave it plugged in and run it over night. The random white/black pixels will clear out LCD burn in. It might take a few sessions.
There's an app called JScreenFix that can be used to exercise the display as well. This issue was a problem on the first generation Fascinates. The samoled screens would retain the image of the status bar clock or the whole status bar.
Technically, it's not burn-in I guess, it's more like pixel degradation in certain color spectrums.

Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.
What else did you expect from a backlit display.

It's not backlit is the point.
Correct me if im wrong here but amoled is, by design, not backlit.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )

It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
Hey some days ago i downloaded an app called Dock Clock. You can check out the app here . In short, what does that app do is displaying a full screen clock and preventing the screen from going off while docked.
it looks like this...
I've also enabled a setting used to avoid possible burn in which moves the clock around the screen in small "steps" every few seconds, but i am not still quite sure if its safe in the long run to use it as a desk clock 4-5 hours a day while charging...
I am not quite informed with the burn in effect so i need your help here.. What do you believe? Will it cause burn-in problems in the long run or its me just being hyperbolic?
Τhanks in advance and sorry for any english mistakes on the post
That app hasn't caused any effects on my S1 afters months of usage. It was in horizontal position so the app couldn't really move the digits but still no issue.
And I do tend to sleep a little longer than only 5 hours
thanks for your helpfull response :good:
You should be more worried about the notification bar because the icons never move and often abuse burn in.
I have yet to see any significant burn-in on the notification bar either across all AMOLED phones I've seen to date.
It's very faint but for most people even hard to spot on an unfirm singlecolored background.
What most people mistakingly report as burn-in is what's called "lazy pixel" where, due to it not being used very often, it's slower and another luminosity than the rest of the screen. Letting the phone cycle a Dead Pixel fixer app for 30-60 minutes whenever it's noticeable will usually get rid of the problem.
I'm not saying burn-in does not exist but usually either the screen has issues or it's been very,very,very abused to be disturbing.

I see... i'll take the chance and ask you something else... 2 weeks ago i realised that on the midle of the right side of my screen there is a small area that appears green on pure white background... you can also notice it on blue-rgb and on red-rgb... the color of that area is nearly the same as green-rgb... its shape is curved like a nail and its like 2mm or 3mm long... any ideas? i read that dead pixels (although the area is by no means a single pixel) appear black on white background and everything else its not dead... can it be fixed or at least do you know how is this "symptom" called?
It's not really a dead pixel in the terms of the pixel not giving any luminescence, thats true.
However several people already reported that their phone had pixels which were incorrectly controlled (e.g. some blue pixels lighting up on red, ...)
which is usually due to a manufacturing fault which shortens the power-pin of several sub-pixels.
With such hgh pixel densities as the S3's screen has, that is to be expected but quality control should get rid of them.
I'd recommend taking a long-exposure photo if available, enhance it, print it out and go back to the seller. The photo should be sufficient in case they are unable to see it for themselves in a store-environment.
You should however first try a Dead Pixel app even if I don't believe it will fix the issue.
Hi. I have the top part of my screen stuck. In fact, in the top part of watsapp(header with name) is stuck on the screen and appears beneath every other application opened that has a light background. I even formatted the phone, re installed android but its still there. How do I fix that?

No. As I said it only appears on a pale background but not on darker colours. Any pale coloured app that opens on top of it, that area can be seen underneath the opened app. An app with a dark colour will cover the area and it is not visible. It's as if that part of the screen is frozen.
maybe hardware issue show in service centre
It sounds to me like it's that infamous oled burn-in case.If you leave a static image on screen for a long time,say,2/3 hours,it'll burn in and stay there as a faint ghost image and you can do nothing about it.Only screen replacement.
Just my 2 cents...

I think you best described what happened. And what exactly should me replaced, the digitizer? Is it worth replacing and about how much will it cost?

LCD+ digitizer.
If you have a warranty - go for it,otherwise it'll cost you alot.
For me it cost 120$.

seriously?
If I put an image staying for hours it can burn into my screen?
That sounds really weird..
Just looked it on the internet, now I'm afraid turning on my phone XD

yep,although i love this deep blacks and rich colors it delivers,this will be my last phone with amoled until these problems will be solved.

I have a samsung wave with amoled, I think that one is a bit better (better dpi), but also better brightness & colors. I love amoled, it makes colors more alive.
I have a new GS9+ (SD, unlocked) which I love.
BUT, does anyone else notice that when viewing the screen anywhere greater than ~10 degrees from perpendicular, the screen turns blue-ish?
The blue-filter option does not seem to affect this effect.
Color shift is a inherent issue with AMOLED displays.

Perhaps, but on my GS7e it's unnoticeable. When doing a side by side with the GS9+ and GS7e the older screen keeps it color at an angle... the new screen does not. :-|
