[Q] Screen Burn-In Questions

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....

newalker91 said:
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.

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

Disadvantages of AMOLED screen

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?

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.

[Q] Can the Pixels on the screen get "burn" in Super Amoled

I use my Gn a lot while driving, and usually listening to some Audiobooks in a program called "AudioBook Player Free"
(link to market https://play.google.com/store/apps/...SwyLDEsImNvbS5mcm1hLmF1ZGlvQm9va1BsYXllcjIiXQ..)
Notmally the screen is always on in auto bright mode...
Now, in dark screens and in whote screen the controls seens to be bruned in the screen asll the time...
I used to do that with my Atrix (LCD screen) and nothing like that ever happened..
Can that be a fauld in super Amoled Screens?
Can it be undone?
Thanks...
(will try to post a picture, but its hard cause I don't have a really nice camera that can get the colors right...)

I had this problem with my samsung fascinate. I really hope this isn't the case with thus phone

Had the same with my first galaxy s. I guess it affects all the amoled phones.
Sent from my GT-I9001 using XDA

no way to maybe recalibrate the pixels or anything?
That sucks.. if thats the price you have to pay for the amoled screens, I'll start choosing phones with lcd then

Yes amoled get burn in very easily. Never leave a static image on the screen for long periods.
Search the burn in thread we already talk about it.

This bugs the **** out of me about the Gnex.
It's literally my only complaint...but one I knew I would have before purchasing.
This is also why I hide my navbar all the time.
You'll probably also notice a navbar burn in if you turn it off/use a video that turns it off.
I, however, use almost the lowest brightness at all times.
This also helps reduce burn.

used my old galaxy s 1.5 years and never had issues with its super-amoled screen.

Is the galaxy nexus screen artificially limited in brightness?

GSMArena did a display test on the galaxy S3 and it is much brighter at full brightness. Galaxy note is also much brighter so why is it that the nexus has such a dim HD SAMOLED screen?? Is it software based so people dont end up with terrible battery time??
I so so wish the nexus can have brighter screen, my biggest complaint with the phone.

Probably better for Q &A, but AOSP and vanilla Google Android has always been overly aggressive about auto brightness and keeps it quite dim more often than not. It can, and is modified by OEMs and some custom roms.

I'm not sure my screen is as dim as what other owners claim theirs to be. I have it on auto-brightness and I don't have an issue with bright outdoors or indoor. I'm not sure I'd like it to be any brighter than it already is.
Maybe I'm not used to having my screen burn a hole in my cornea.

I am talking about full manual brightness, auto brightness is never perfect on any phone but it actually isnt dim at all on my nexus S.

Dunno. I am not about to go run to Best Buy and compare, but full on brightness on my phone is uncomfortably bright in the dark and dimly lit areas, and very visible in direct sunlight.

I tried the phone at a very brightly lit shop. Put the brightness to maximum manually and yet it was barely brighter than my nexus S at 50% brightness.
Brightness isnt a contest where every phone should try to beat others but it should be sufficient enough. I just think the nexus brightness isnt sufficient, it tops out at 200 nits when the minimum should be 300 nits for comfortable use in all environments.

Do you want a discussion, or do you want to discount what I am saying just to argue?
Don't ask for an opinion if you are just looking for a way to discount it.
Your sites cannot vouch for my experience.
If your phone can only match 50% of what the Nexus S can in brightness, there is something wrong with it. That or you are exaggerating. This is in my opinion, but I think it is a very valid point.

The screen seems to be limited in brightness from the factory, as a matter of settings. Using AOKP Rom and increasing the color multipliers makes the screen much, much brighter, but i've read speculation that it could cause the screen to burn-in images much faster, which logically speaking, seems to make sense. Maybe it's limited by Samsung for that reason. This particular panel seems slightly more prone to image retention than the one on my Droid Charge, granted it isn't the same as burn-in, but maybe an indicator of inclination toward it...

The GSIII probably gets 2 mins of battery life. A screen that bright on 4 Cortex A9's and 4 mali 400's at 32nm....the battery is going to SUCK.

I was not asking for opinions if the screen is dim or not but why is it. It wasnt my phone but a demo model at the shop. My experience showed me it was dim just like I had read in reviews.
I have an LCD nexus S, I am sure the AMOLED one at 50% wont be almost as bright as gnexus at 100. You know LCD's can get much brighter and the one on nexus S is particularly really bright.
I also compared galaxy nexus side by side with galaxy S2 and the difference was noticeable in brightness.

The GS3 is only 300 nits bright, it isnt anything out of the ordinary. The one X has 500 nits screen.
And nobody is forced to keep the screen on high brightness, it's just an option to have a really bright screen and a pretty good one at that.

I thought of it when you mentioned the GS2 - I had that phone for a week when it was released on Sprint, and any time the screen brightness was turned up and the screen was on for a few minutes, it would overheat and the OS forced it to low brightness until it cooled. At the time it was an issue quite a few people seemed to be having, so maybe it's limited on the Nexus for temp reasons too. As Smokeey had mentioned, battery life could be a factor as well.

Why cant I post if I dont have the device? I am thinking about upgrade from nexus S and I just made some threads about the potential issues I discovered about the device.

As long as you can see the screen who cares how bright it is. Are you trying to light up a room with it? Also, keep your phone on full brightness and you will be highly risking screen burn in so I would not recommend keeping it on full anyway even if it is not as bright as other devices.
Why would anyone purchase a phone or not purchase a phone based on it being the brightest screen out there. I can understand if you couldn't see the screen, but really? And now with the ability to change the colors and gamma of the screen, it just looks great.
So if you get the Nexus and keep the screen turned all the way up because you needed to light up your house to save money on electricity, please don't start a thread complaining about burn in.

hehe, i bought googles flagship for 450€ and i need to care how long is screen on and i cant have it on full brightness all the time becouse i "risking screen burn"?

Ah keep LCD phone on full brightness and deal with the terrible blacks. Keep an AMOLED phone on full brightness and deal with burn-in. A perfect world we do not live in.
On a serious note screen brightness matters most when going out in the sun obviously. It can never be too bright when you are out.

HD Super AMOLED Eyestrain?

Does anyone else experience eyestrain with devices that have the HD Super Amoled screen?
I notice after about 10 - 15 mins of use, I get dizzy and my eyes hurt like they are being crossed or something when using the galaxy s3 or galaxy note, my old galaxy s2 skyrocket doesn't bother me though....
I've tried to turn the brightness down all the way, using the device at different distance to no avail.
Any possible solutions to remedy this? or am I going to have to sell my new S3 like I did my galaxy note? :/

depends on 2 very important factors...

I've actually noticed a decrease in eye strain coming from an LCD screen on my atrix. LCD screens are constantly flashing, and the screen on my galaxy s3 is super clear for me almost no eye strain. Its probably personal preference though.

I've actually experienced the opposite as my first android device was an atrix....
I think it may have something to do with the 1200 x 800 resolution on such a small screen because If I turn up the resolution on my PC HD monitor to something like 1600 x 1200 for example, my eyes start to hurt.

I was actually going to post a new great until I saw this. I came from retina displays and my eyes are sore after I look at the screen for over 10 minutes on my GS3. Kinda concerning!! Might have to switch back to an apple product. I was getting use to droid too. :-/

its because of the screen size/pixels. Your eyes still needs to be adjusted to the new screen lol... obv

Yes!
I got vertigo/migraines about a month after getting my S3. I had a number of medical tests to see what was causing it - but even after new glasses I've narrowed it down to the S3 display being too strong for my eyes. I'm going to sell mine and get a replacement with a duller screen.

Try this...
Try changing the Screen Mode to 'Natural' or 'Movie". Helped a bit.

I also immidiately noticed eye fatique after getting Galaxy s3, particularly in my right eye. It started only getting worse, and coincidently only when I was using Galaxy. Other lcd devices such as older 3gs never bothered me at all. Surpisingly majority of reviews call the display stunning quality, but its pretty dim, practically unusable outside and colors are unnaturally oversaturated, all of which didnt bother me that much as long as my eyes wouldnt hurt so much. I started reading more about specs in Super amoled technology, but nothing pointed out to potensial issues, than I googled galaxy s3 refresh rate, and the first video from the search result comparing s3 to the iphone, provided a major clue. The poor quality camera was picking up horrible flickering from galaxy, but iphone screen didnt flicker at all. It instantly brought me back to old CRT days, and I also remember getting dizzy from such displays running at low refresh rates of 60mhz. Back than bumping up refresh rate to 75mhz conciderably dicreased eye strain. I took the video to the store, sales person was suprised that I was returning such popular product, but its been a day since my exchange for another brand and eye strain is gone. The issue maybe overlooked as it affects low percentage of people, but if you have sensitive vision, than you'd be much better off with non hd amoled technology

Could it be the brightness?
I'm sure your not holding it against your nose while watchin you tube, but maybe its the overall brightness of the screen thats getting to you? I use a powersaver app that has a black screen filter that dims it out a good little bit, maybe something like that could help, or a matte finish screen protector...the anti glare ones I think.

Use the "Screen Filter" for use at nights.
Set brightness to 0, and enable filter. I set mine at 48.6% and 36.9% (created two widgets with these percentages) and use either as needed.

Set your brightness lower. It's the brightness of your screen. I have the same problem before turning down the screen

Keep phone at safe distance from face. Try a dark theme or inverted apps, or both they will most likely reduce eyestrain as well as save battery.

Seems ok to me with brightness anywhere from dimmest to 50%.

hmm, can't say I've experienced any strain.

The cm10 rom is extremely bright too, at half, I started getting headaches but on stock, I can state at near brightest all day.

Hi all,
There are a lot of users who feel uncomfortable with AMOLED displays (not all of them, for example sgs2 is not affected). They can struggle with head ache and eye strain. You can google "galaxy s3 eye strain" for example or watch how AMOLED blinks through photo/video camera (there are tons of youtube videos). This effect apperars only when screen brightness is not at maximum level. The nature of that is the mechanism used for brightness control. Instead of forcing the pixels to glow at less brightness they force them to blink very fast. The faster pixel blinks - the brighter it seems to the user. The downside of this is that the whole screen blinks as an old CRT monitor which causes this negative effect.
I found an app which could help us to workaround this issue. I filed a feature request. So if you are interested you can add yourself to wathcher list and post a comment here - https://bitbucket.org/VitoCassisi/lux/issue/38/lux-auto-brightness-feature-request-for
This should not take a lot of time since you can authorise there with your google/facebook/twitter or other account.

Wow! I switched the screen to "natural", the problem with oversaturared, too rich colors was solved. I had to keep the brightness low so color pictures aren't too bright, but this made reading text on white backround unpleasant. Of course now I have to find new brightness levels (what brightness levels do you guys use for day and night?)
PS: Samsung has been doing similar tricks with the colors in their TVs. Some series 6 TVs made the picture look like it was from a heat sensor in dynsmic mode, and this was their default mode.
PPS: Mobile screens suck. LCDs have washed out blacks which strains the eyes, and AMOLEDs don't care about correct colors which makes you duzzy.

S3 screen flickers!

You are absolutely right. S3 screen flickers a lot. Try to move it quickly in front of your eyes, move your eyest when looking at it, or move your finger fast in front of the screen. I certainly do notice it.
What other phones have better displays? Sony? HTC?
I have a solution to resolve galaxy S3 scren flickering: set brightness to max in settings, install an app like "Screen Filter" (one with black-white rectangle) and decrease brightness there, in the app.
Flickering gone!

Most of phone LCD screens are not affected by flicker. Even some amoled displays too. For example old HTC Legend and galaxy S2.
Galaxy note 3, 4, Galaxy s4, 5 are also affected. I strongly recommend you not to buy any new samsung phones equipped with AMOLED screens.
Now with this https://play.google.com/store/apps/details?id=com.vito.lux software you can get rid of screen flickering issue. Automatic brightness adjust will also work.
