I have an Epic 4g Touch (SGSII), and am wondering about screen burn-in.
I already know it's possible to burn-in our Super AMOLED+ screens, but I'm wondering what kind of things I can do to prevent it, and if doing certain things will accelerate the burn-in or not.
1. I'm mostly indoors, so I always keep the brightness set to 30%. This should be sufficiently low to slow the burn-in, correct?
2. I use ADW Launcher Pro, but I don't have it auto-hiding the notification bar. My screen is on between 1-3 hours per day. Should I be using the auto-hide feature?
3. I was thinking about using the clock in dock mode at night while I charge my phone. I set the brightness to the lowest possible setting, and I know that after a few minutes, the phone sets a black background with the clock text being yellow and moving around the screen every minute or so. With all of that in mind, is that going to be bad for the burn-in?
4. This is kind of related to #3. If a pixel is pure black, is it susceptible to burn-in?
Thanks in advance to all replies. I'm pretty tech savvy, but kind of a noob when it comes to these advanced screen questions.
Awesome, thanks. Wasn't aware of that strobe trick; I'll have to start doing that

My suggestion to reduce any and all burn-in is the same trick used to fix stuck pixels on LCD screens. Download a strobe light application that uses multiple colors, and once every couple of weeks allow your phone to sit while your screen rapidly flickers through all of the colors for about 10-15 minutes. This will wash away any burn-in that may be building.

I just had a thought...
Isn't burn-in caused by pixels becoming physically damaged? So how can a strobe light app that uses these damaged pixels "wash away" burn-in?
Not trying to be rude or anything; I definitely appreciate everyone's knowledge on this subject. I guess I'm just looking for more information.
personally i wouldn't worry too much about burn in. things move around enough on these phones to mostly prevent it.
and for what it's worth i still use my original samsung launch day moment as a clock for the last year or so and have yet to notice any burn in at all (and that clock doesn't bounce around) sometimes during the day i still use it as a media player or terminal device too. screen still looks awesome (not compared to the gsii but)
granted the moment was super amoled not super amoled+ but heh....

No, the Samsung Moment was sure not Super AMOLED. It was LCD. I've taken probably a thousand of them apart.

you sure? the og box i have on my shelf def says amoled.
EDIT. ok maybe its not SUPER AMOLED. But it def is AMOLED.
"3.2-inch AMOLED display"

the only difference between amoled and super amoled is the PenTile RGBG pixel matrix is replaced with a common RGB subpixels arrangement, going from eight to twelve subpixels in a group, resulting in finer details. The screen technology is also brighter, thinner and 18% more energy efficient. super amoled+ adds more of the same just brighter lighter and less power hungry.
yes any led panel (amoled and super amoled) is just an led panel thats true.
its the material used for the led catalyst (organic) and position of the film in the glass (under not over) that differentiate them.
but then again it's really not an issue. and i could be wrong.
all i know is that my moment has been left on in situations that i know would cause burn in on any normal lcd style device and has never been an issue.
for the length of time that most people keep a phone (2years or so) i personally wouldn't worry about it.
that being said OLED pixels degrade with use (become dimmer, and the different colour pixels degrade at different rates), but according to most screen datasheets ive seen we are talking 15-20,000 hours of screen on use for a noticeable difference.
just ask yourself this do you ever see screen burn in on display phones that are left running screen on all day?
but didn't mean to push the thread offtopic
I have seen burn in on my Captivate, so yes it will happen.
yep it will happen in certain circumstances i just went looking through my old amoled info and found this link
http://data.4dsystems.com.au/downloads/micro-OLED/Docs/4D_AMOLED_Presentation.pdf
this has a lot of good info but is out of date.
what we get isn't true burn in (although the outcome is similar)
what we see as burn in is really the degradation of pixel intensity and has alot to do with the colors the screen must display. so even a moving clock is degrading the pixels just that it's degrading them (hopefully evenly across the screen) the super amoled+ screens seem to have added a white led to the mix to help prevent burn in from white screens/txt and lower power consumption.
it also appears some colors are better for screen life than others with blue having the shortest life.
keep in mind if your interested in looking at the link that it is describing the first gen amoled screen and much has been improved since then.
from this i would also make the assumption that flashing the screen doesn't unstick any pixels it just burns them all out a bit.
i'll shut up now
Well I've done some more research too, and found that what mjcollum said is pretty much the case for us. We don't actually get a "burn-in", but rather the pixels degrade and leave a sort of "ghost" image where the degradation is worse than surrounding areas.
The "half life" of older AMOLED pixels was 14k hours, but most articles I've encountered mention that technology has improved, ergo the pixels should last a bit longer in our Super AMOLED+ displays.
But still, there will definitely be some degree of degradation. I suppose it's a lot like sex; leaving the screen off will keep your pixels the safest, but it's a lot more fun to use what you've got
I only wonder if a dim display degrades slower than a brighter display... ?
interesting. good to know.
does this apply to qhd displays like the photon also? or is this only a amoled thing?

The moment was AMOLED... it had a seperate digitizer.
The Galaxy S was Super AMOLED it incorporated the digitizer with the pentile matrix.
The Galaxy S II is Super AMOLED+ which replaces the pentile layot with the standard RGB grid.
To prevent burn in limit screen on time, no need to do any crazy pixel unsticking tricks as it'll just reduce the vibrancy of your screen.
thanks warlord good to know.
one thing to think about is even if the pixel halflife is only still 14k hours
365(days) x 24(hours) = 8,7650 hours if you left it on for a full year.
so i say just use the thing.

i could be wrong but i believe the qhd part just references the resolution.
and the photon has a normal style lcd display. so if it got burn in at all it would be the normal lcd style.

You're correct, qHD only references the resolution, not the display type. Which is funny, because a lot of Google searches are for "qHD vs Super AMOLED+". I think people are just trying to pit their Droid Bionics against our SGSIIs
Hi all.
Last night I accidentally discovered the burnt pixels on my one year old Focus screen The sights of high contrasts Metro-style icons (such as IE, phone and marketplace) are visible on the white background as a darker "shadows" (actual color is like a light-light yellow, close to white). These "shadows" are visible on the white background in the dark only.
It's not a big deal but I'm kinda disappointed
So, my conclusions are:
- high contrasts Metro-style tiles on the home screen are evil, at least for AMOLED screens. However live tiles (probably) can solve the issue (he-he, just thought - may be it's a real reason why MS implemented and pushing live tiles? Kidding );
- periodical changing of tile location on the home screen also can help;
- using AMOLED handsets for development is not so good. The best practice is to keep AMOLED screens off all the time (what is not acceptable for development).
My Focus is one year old, but I don't have any burn in problems some reported. Granted, I don't leave my phone screen on for extended periods, but my live tile arrangement really never changed.
Now that I have the HTC Titan, I have no regrets with the SLCD screen. The colors seem more natural to me. While AMOLED screens certainly have a "pop" factor, it's not a must-have for me.
This is a well known issue that you have to live with: AMOLED will get screen burn-in if it is use for an extend period of time.
I know most of the Android Galaxy phones also have screen burn-in especially on the status bar.
My own Samsung Focus developed screen burn-in (esp. Metro buttons) after only three months of use.

How about Super AMOLED screens, is problem still persists?
I notice things on my Omnia 7. Normally if i've had a menu open for a minute or more and i switch to a black background i can see a kind of greyish imprint of the last displayed icons.

SAMOLED has it as well. I'm sure it was a big issue in the focus forums last year
The biggest disadvantage of an amoled screen is when you move to another type of screen, and notice just how gray blacks can be. Using my old focus and having the blacks blend with the bezel was so visually pleasing, and the colors had so much pop. I hear that the colors aren't as accurate, but what does that mean really? 90% of what I look at on a phone is arbitrary colors anyway; how would I ever know that the blue tiles are really supposed to be one shade vs. another, and why would I care?
(btw yes, I had the same screen burn-in problem on my focus)
Yeah i had a major burn in problem with my Omnia 7, I think it was something to do with the bright blue theme i used, i have pictures here: http://forum.xda-developers.com/showthread.php?t=973337
use a screen saver?
Oh ya.. nevermind
Wow... I had no idea of this...
I have a Galaxy S I9000 (as well as an LG Quantum) and luckily it hasn't burnt in...
Is this a really wide spread problem?

Try to look at your screen in darkness (set white background on the fullscreen first), then say "luckily"

The problem is particularly bad on Super AMOLED screens.
Super AMOLED is still AMOLED.
My Vibrant, if I turn my screen on to the home screen and let it sit there for 10 seconds and then open another app, I can see the shadows on the home screen superimposed onto the app that's running. It's very noticeable, and gets irksome after a while. You won't see that on LCD screens.
The status bar is burnt in, which is noticeable when the phone is used in landscape mode because you can always see that faint strip where the status bar is (in portrait) on the side of the screen.
I set my screen timeout to 30 seconds to "preserve" the screen.

All of Samsung's displays have this issue. Perhaps you just haven't noticed it, or are just fortunate
Not really widespread, and not really a "problem" per se. Just a component of the screen tech. It burns in and shadows easily.
However they have better power management than LCD screens and better brightness, viewing angles, and outdoor visibility - as well as better color saturation and reproduction. For example, I increase my Vibrant's stock battery life by like 4+ hours doing absolutely nothing but putting a true black background on the launcher...
It's a trade-off. It's worth it for someone like you who doesn't notice it, though. It's worth it even for some people who do. It really depends on how long you keep your phone, Lol. If you upgrade yearly it's not that big a deal. I can't see myself going 2 years with the Vibrant as my primary device and dealing with it, though. It's too startling to look at at times, especially after you spend a significant amount of time in one app with static UI elements and move to something else...
If you look at the AMOLED technology, it's understandable really. All the colours displayed on the screen are composed of green, red and blue sub-pixels.
In an AMOLED screen, there is no backlighting. The sub-pixels themselves generate the visible light, hence why the blacks are so black, because the black pixels are not powered on. (Think of an AMOLED screen as having thousands of tiny tiny LED's)
However the problem with AMOLED is the manufacturers could not produce a specific chemical compound for each colour that would wear evenly. For example, the blue sub pixel has a shorter lifespan than the green. When the AMOLED sub-pixels gets used, the intensity of light produced decreases, hence there is uneven wear. The pentile arrangement was to actually arrange the pixels in a way, which as the display wears, the colours look normal. When there are static pixels displayed, a certain portion of sub pixels gets used more than others, hence why you can notice it.
In an LCD, each sub-pixel is a polarizing filter, which filters out either red/blue/green and displays it or blocks it, so an LCD doesn't suffer from screen burn in as much as AMOLED and PLASMA displays.
From day one I have only ever used my phone on the lowest setting and I have alternated every few days from red/green tiles. I have never used blue due to the low lifespan of blues!!
I don't think it's a huge problem if you are smart. I made the mistake of leaving my screen on as often as possible when I first got my focus. Once I started noticing the burn in, I moved my tiles around, put my screen on 2 minute timeout, and didn't notice any more of the burn in. Just the original images.
As Big K mentions, blue pixels are the quickest to degrade, that is why you never use a blue theme with an AMOLED display. Also, displaying white actually activates some blue pixels and draws more power, so the black system theme should always be used over white.
Every AMOLED owner should know these 2 things and it is a shame that Samsung and the carriers don't do a better job of informing their customers of these simple facts.
I cringe every time I see an AMOLED phone with a white background and blue theme.
This is why I still stick to Super LCD.
I saw an S2 get a burn in within 2 months of use. Lawl.

The solution is ridiculously obvious: turn off your screen when you're done using the phone. Duh. That's obvious from a simple battery life perspective.
Of course, I see people *constantly* who just set their phones down with the screen on and walk away. Idiots.

The solution is not ridiculously obvious because other screen types do not suffer from thsi issue, therefor the user who moves from an LCD screen to an AMOLED has absolutely no clue that this screen type has these deficiencies. They simply assume their screen will always look the way it does as long as they take care of their phone.
That is not a bad assumption. It just doesn't jive with this display tech.
I love the deep blacks and color saturation on Samsung's AMOLED screens, but I don't think I can ever convince myself to get another one.
The issue isn't just keeping the screen on. I've always used a 30 second screen time-out on all my phones, so they aren't just sitting there a ton with an image on them. Even when you have something on the screen for like 10 seconds and move to another app you can see the image shadows on the screen. Yes, it gets pretty noticeable after a while to the point where it's constantly drawing your attention.
It's actually worse than the PenTile they use in the 1st gen SAMOLED screens, TBH.

1st gen? It's being used in the Galaxy Nexus, too
It's a really useful point to raise, and something to think about for people using their phones for development. Automatic screen time-outs can be an annoyance when you're testing features (against a real device), and wanting to stay connected (in visual studio) to the phone for debugging info and deployment. I know I have my current phone on most of the day to test tile and page updates etc. so there's bound to be large areas of the screen remaining static for long periods of time.
It's made me think twice about getting a Lumia (which I assume would be prone too) for this reason
I'm surprised manufactures don't include info on it bundled with the phones (e.g. on not having a white background) - that's pretty irresponsible.
I've never used a Pentile (or an AMOLED) screen before, so forgive me if this is a common problem... But if I stare at the screen on the SGN too long (i.e. watch Netflix), I see a strange dot-like pattern that sticks with me for while... Then eventually wears off.
It's very subtle, and I mostly notice it when looking at darker objects, or into shadows -- but it ends up seeming like everything I look at has this digital texture on it. Perhaps this is because of the OLED nature of the screen. It's like staring at very tiny, very bright lights in a kind of checkerboard/hatched pattern... It seems to leave an impression on my retinas.
It's bizarre and I was just curious if anyone else was experiencing this?
I have the brightness on the phone set to 70 percent... perhaps I should lower it? (most of my viewing is indoor.)
Lay off the lsd. But yeah lower your brightness. That's too bright to normally view for long periods of time unless you're using it in the sun or a brightly lit room.
Sent from my Nexus in Texas.
When I was dating my ex, I always kept our text conversation open on my Note 4, and my Note 4's screen was set to never sleep/dim while plugged in. I had the screen on with our text messages for probably 8-10 hours a day for months.
Now her name, phone #, the keyboard, texting app, everything is burned into my Note 4 screen. It's really bad and noticeable in every app.
I tried running the screen burn-in fixer (that flashes different colors every 2-3 seconds) for over 18 hours and it did not seem to help the problem.
Does anybody know of a fix? Could I perhaps open a pure white screen for two days and hope that burns in?
There's really no fixing it. OLED screen burn-in is a brutal thing. If you're lucky, you might be able to get it replaced under a warranty.
The important thing to do is to learn from the experience. I mean that sincerely, and I hope it doesn't come across as at all condescending in tone. Going forward, if you get an OLED device, you'll want to make sure to avoid letting things like the status bar stay the same color for very long periods of time, and shorten the time before the screen shuts off.
---------- Post added at 03:40 AM ---------- Previous post was at 03:39 AM ----------
Your idea to potentially resolve it with a pure white image for an extended time, as I understand, is generally effective with LCD technology, but not OLED.
To understand why running the screen burn-in fixer for 18 hours will not fix it, you must understand how OLED, and plasma display panels, and even old-school CRTs work.
All 3 display technologies have self-illuminating phosphors. OLED panels use organic LEDs. Plasma display panels use tiny cells filled with, well, plasma. CRTs use phosphors which are illuminated by being bombarded with electrons. These phosphors slowly degrade over the life of the display, and as they do so they grow dimmer over time. By the end of their long production run, CRT phosphors reached the point where they would not noticeably dim during a human lifetime. Plasma phosphors never did, which is why burn-in was possible on the very last Panasonic plasma TVs that were manufactured before the whole thing was scuttled by the nearly bankrupt company.
Now we come to OLEDs. OLEDs are still a very immature technology and the problem of phosphors dimming rapidly and having a short lifetime has not been solved. There is a reason why LG is purposely using white OLEDs with an overlaid color filter on their OLED TVs. Samsung attempted to make OLED TVs for mass production using RGB OLEDs but withdrew from the market while they worked to improve the effective lifetime of the OLEDs, especially the blue ones.
So what actually is burn-in? It's simple. If you leave something showing statically on the OLED panel forever, such as your text message window, the illuminated OLEDs will drastically dim relative to the ones which are dark. What you're seeing is uneven wear of your OLED panel. Some pixels are worn out a lot, others are mostly unused.
Now you understand why your burn-in fixer will not do anything. Because the burn-in fixer shows static, full screen colors, it will wear down all your OLED phosphors evenly. This will never fix burn-in because you have some which are worn down unevenly, so wearing all of them down more does nothing!
Some people have attempted clever solutions, like taking a color-inverted screenshot of their burn-in and displaying that for a long time to try and wear the non burned-in pixels more to match the wear on the burned-in ones. This may theoretically work, but you must leave this image displaying for as long as you displayed the original screen that caused the burn-in. In your case, since you left your ex's text window on the screen for months, you will need to display the color-inverted image for months to wear the non burned-in pixels enough to match the burned-in ones.
My point is that you should just throw your phone away and buy a new one. You have basically destroyed your phone's OLED panel, chalk it up to a lesson learned and move on. Turn the damn screen off when you're not using your phone!

This thread is now over a year old, and I don't know if you've thrown away the phone by now/had the screen replaced under a warranty as user Bicknasty suggested/something else, but here's a relatively simple solution I'm surprised no one else has mentioned:
While you can't actually get rid of AMOLED screen burn-in per se, you can certainly burn in other parts of the screen to the point where everything is burnt in about the same and the difference isn't really noticeable. You would do this by first pulling up the exact image that's burnt in (go to screen you had open for so much time that it burned in; you might want to take a screenshot and edit out all the dynamic elements of the user interface like the stuff on the notification bar and individual messages, so that you don't end up with those burnt in when you're done), then inverting the colors (you can find an option to do this in the settings application), and then leaving that image open 24/7 until the burn in of the inverted image has canceled out the original burn-in (you should check on this periodically by pulling up a white image that fills the screen). Remember, this won't technically get rid of the burn-in, but it'll make it impossible to notice. Good luck
So my screen is having issues when I scroll and I know this happens on this device. The question is do all the devices do this or is this just an issue with certain ones. Is my phone broke or will it be fixed with an update. The smearing is pretty bad and I notice it even with the brightness turned up.
Every OLED device I have has done it, but I haven't had an LCD device for a while. So I don't know if it's a characteristic of OLED screens or all screens. My last device was Samsung and had it pretty bad.
I'm having the same issue,
It bleeds/smears with dark/black color when used in dark i.e no light in the room.
I think it happens all the time, just that its visible and annoying when we use it in dark.
What did you do? Did you get it replaced?
Hi!
Same here... It seems normal, anyway with two years warranty if something is wrong with screen (black bleeding, burn in, ...) Google have to repair it or change the smartphone.
Regards!
It should only be visible in low brightness. It's normal for oled but the pixel 2 XL is a bit noticeable because Google set the gamma to high. So it can actually be improved through software.
If you see black smear etc during the day and any other time than maybe at night when the screen is at low brightness I would rma it
Seems like sensors are causing problem if move phone around in dark it will go away I have a case and tempered glass on phone
