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.
Many people out here are talking about issues with screen bleed on this tablet
I think that the issue here is there are 2 different screen issues with this tablet that people are referring to collectively as light bleed:
1)Screen bleed
2)Edge lighting visibility
Screen bleed as I define it is something visible usually on a dark background where white light leaks out on certain areas of the screen. Almost all LCD have some degree of this and some are better than others. Often increasing the display brightness on the drak screen magnifies it. And fleing the chassis of the tablet often will shift where it bleeds.
This tablet does have some issues with this, more so than my Nexus 7 ( I lost leaving it on a plane) did.
Edge lighting issue many have posted pictures on here an youtube calling it screen bleed is something different. It seems to consistently be the bottom of the tablet in portrait mode. It is most visible on a white not black background and at lowest intensity (non auto brightness of less than 20% and it is noticeable). IT is always 7 bright/dark areas in sequence. While I am no expert in LCD technology, LCD compared to Amoled have a backlight. If the backlight is lit at the edge, it is quite likely that as one lowers the screen brightness the edge lighting at its origin might be slightly brighter than the surrounding area giving off this effect. Above a certain brightness the edge lighting is overwhelmed by the brightness of the panel and is no longer visible
For those that don't understand here is a video someone posted on youtube that demonstrates on his GPAd what the edge light issue is:
http://www.youtube.com/watch?v=SmiSEC3rbHI
Now I replaced my first tablet (white one) because it had this and significant light bleed.
Picked up a black one and the light bleed is negligable. below 50% brightness it is not there and truthfully light bleed is an issue more when viewing in darkness where there is little ambient light and corners of the screen wash out with light. The fact I have none is great!!!
But........I have the same issue of the 7 areas of brighter whites at the bottom edge of the screen when brightness is below 20-25% (non automatic).They are mostly noticeable against a white background and more so when in full screen mode or white button bar is selected, or if using in landscape mode where it will then show on the right side of screen.
I am torn as to whether I should return or not. Seeing the many who have same issue and it now being there on 2 tablets from different stores and different colors (hence different manufacture runs) I suspect that this is more or less present in all G Pad 8.3 tablets. Some of us are just more likely to see it as one needs specific situations for it to be visible.
I loved my nexus 7HD before i lost it. Though I had some issues with it:
While 32gb, no expandable storage
touchscreen was not the best
Was feeling kind of small given I have a note 3 as my phone.
As such I decided to get a replacement. My final candidates were:
Ipad Mini retina display- Great Screen and app ecosystem (wife has ipad so lots of apps purchasesd as well...) But, 100$ more no expandable storage and stuck in the walled garden. Plus already have large selection of bought apps, and books/magazines in google play.
Amazon HDX8.9- I think this is the best hardware out for the money. Still light, large vibrant very bright hi res screen with insane battery life. If there was a way to get stock android on this I would jump on it. But Amazon store is limited and side loading while fine for the odd app is not how i want to fill my tablet. I can't customize it as far as looks go and while some google apps can be side loaded they don't al work or work well and there are a lot of FC. Also being in Canada, Amazon prime doesn't really benefit me as the video and music services are not available there. IT is a shame as I think I am still tempted to buy this tablet just based on the great intermediate size with best hardware
Gpad I thought this would be the perfect replacement for my Nexus 7HD. Based on reviews the added screen size without much weight and loss of pocketability. A still vibrant high PPI though dimmer screen (don't really use out doors much and seemd fine sitting in my car today leaving bestbuy). While not on latest kitkat there are good roms out there and likely can eventually swap out software fro GPE should I want. Meanwhile the LG skin adds some cool functions like Q slide apps, knock on qpair.....Seems like it is the right size, right resolution, expandable storage Better speakers than Apple... If I didn't have the edge lighting issue this tablet would be near perfect. I don't mind slightly less battery life as I will be able to charge it at night and seems most are getting 6+ screen tme and 1-2 days stdby.
Windows 8.1 Tablet (Lenovo or Dell Venue Pro Intriguing and right size at 8 inches though decidedly lower esolution and would have to forego my library of google play apps ....though having windows and full office could have some value though there is no current way to get a wired connection to a monitor or TV.
So.....in spite of the EDGE light screen issue, what should I do?
What are those of you who have noticed same thing doing or have done?
Hmmm now I am not sure what to do.
First one I bought was a white one. It had traditional light bleed in 2 corners and had this bottom edgelight issue at low brightness.
Returned it for a black one. This one is better in that it has no light bleed except the bottom edgelight issue. This occurs at brightness below 20-25. IT is not an issue during day time as I am needing brightness above 40 to comfortably enjoy the screen.
But for night time use I have to kepe the tablet a bit brighter than I prefer so as not to see it under some circumstances, I.e. landscape viewing.
I am trying to decide if it is worth returning as I love everything else about it. I am on vacation in the US and do not have the time to keep going back and forth to various best buy locations hoping for a better unit. Especially since seems the black model is in limited supply with nearest store 30 minutes away. However also given the exchange rate on my credit card, Returning it will likely cost me 20$ based on how the Credit card companies charge....
Have you tried using a screen filter off of Google play store. I used one on my galaxy 7.7 for night time use.
I would see if a third time is the charm. Return the unit and ask if you can turn on an inspect the next unit before leaving. See if you can find one that is acceptable before walking out the door. To me, the G Pad is best unit out there in the 8" space. Fire HDX8.9 is nice, but as you mentioned, it doesn't support the Play Store and requires everything to be side loaded. Additionally can't really customize the UI at this time. Hardware is killer, but until you can drop standard Android UI on top, G Pad is better option. In regards to Ipad Mini, it's nice, but absurd at that price. If you were to go for iOS, better off with the Air as it can be had for about $60/70 more. To me the Windows Tablet is not really an option. Depends on what you plan to do with it. I've read mixed reviews with the Windows Tablets. Good for some productivity apps and browsing but not so great at gaming. Still do quite a bit of games, so for me not an option.
Again, recommend giving it one more try and exchanging the unit and see how it goes.

Thanks for the advice. ...
Went to a third best buy location tried 4 different gpad as salesman let me test them.
All had same issue. I will keep it anyway. Switched for the white again though. Prefer the feel of the back and no finger prints

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.

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
I had ordered OP3 on the day of launch and got it the next day. After using the phone for about 5 days, I noticed that the top part of the phone had a bad pink tint which was clearly noticeable on White and Grey backgrounds at any brightness. I sent the phone back for replacement and got a new one few days back. The phone looked almost perfect and have been using it for around a week now. Yesterday I bumped on another thread in a forum when I saw a peculiar screen uniformity issue in only one particular shade of Grey.
Steps to reproduce the issue
1) Open the below link in Chrome in a dark room.
http://www.nullabletype.co.uk/static/styles/blah2.html
2) Reduce the brightness to just above the minimum brightness (5-10%) with adaptive brightness turned off.
3) Go to Display settings --- Turn on Night mode --- Increase the slider below to the maximum.
4) Scroll to the 3rd image (the one after Black)
5) Mine has uneven brightness. Some part of the screen is darker than others.
6) Increase the brightness to say 25-30%. Everything looks uniform.
7) Scroll to other images (other shades of grey) and no screen uniformity issues at any brightness.
Now, I am not sure if I should send this back again. I don't use such brightness levels even in night and I don't see any screen uniformity issues in any other brightness levels or shades. I also searched in internet and found similar issues being reported in Nexus 6P, S6, S7, etc in Reddit, xda, etc. There are people who have RMA'd their devices 5-6 times without much luck. From what I have understood till now, AMOLED's are not really perfect in displaying Grey at extremely low brightness. Or may be, its due to the current software targeting the NTSC Gamut ? Anandtech recently said that sRGB update (coming in 3.1.4) has made considerable improvements in Greyscale accuracy.
Before I even think of sending the phone for 2nd replacement, I would like to know how's the screen uniformity with others here.
I did the screen test the moment I got the phone everything turned out good, I was really worried after reading the reviews on the net about the screen. But it seems like only handful of people are facing the problem.
Can you please let me know how you tested it ? I too had tested it on Day-1 since this is the second OP3, using "Screen Test" app and everything looked good. Only one particular shade of gray at low brightness creates this problem.
Not exactly 'real life' usage?? Haha
Looks fine on mine. Uniform grey across the whole screen.
Yeah I definitely have the same uneven brightness on the dark grey on the right side, it's even visible on the notification drop down. Like you, I'm wondering if it's something that can be fixed, or something I should bother RMAing, am I just gonna have the same thing again? It's strange, it looks like uneven backlight but there is no backlight.
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
