I own both Samsung Captivate and Focus, both devices have SUPER AMOLED screen. Both devices have burn-in problem after months of usage.
Captivate:
I could see the notification bar on top of the screen with the fuzzy clock and battery indicator burn-in to the screen with very pale color especially very noticeable with a white screen! I also saw AT&T stores had these demo units experiencing the exact problem! I then called up Samsung to replace the Super AMOLED screen. Now it's fine but very annoying.
Samsung Focus:
I just got mine in Dec and didn't use a lot on that device. There is a very good reason why WP7 has to hide those status indicators on top to prevent Super AMOLED screen burn-in problem. I also checked out the demo units in AT&T stores, all of the Focus had Windows Phone 7 logo burn-in to the screen at the top left corner due to the static logo constantly playing on the demo mode.
In conclusion:
SUPER AMOLED screen's quality life-time is still short compare to LCDs. Given about 2 months of usage, 8 hours a day with static image such as notification bars for example, burn-in issue is inevitable! In real-life daily usage, give it about 2.6 hrs a day, your screen will be burnt after 6 months.
NEVER USE SUPER AMOLED SCREEN WITH STATIC IMAGE!
On my phone the screen isn't on for very long periods. Even when I am talking on it if near my face the screen is off.
How does this compare to your experience?
Does a phone in demo mode have the screen on constantly?
The only reson OLED isn't so widely used is because of its limited life span (especially on blue color). From what I read in the past, it is very difficult to get blue channel pixels pass 2,000 hours of life span. Not sure if AMOLED or SAMOLED made any advancement in this area. So, the precautions should always be taken. Let your phone screen on 8-hour a day is not a good approach. That's why there is a setting to let phone go into sleep and turn off the display.
My Captivate has been working flawless since August 2010 with zero image retention or burn in.

How many hours per day do you keep your screen turned on? I would give that minimum 480 hrs with static image to experience burn-in. No need to wait 2000 hrs of life-time in Blue Channel in AMOLED.
The life-time of the entire Super AMOLED is here and I'm also being conservative: 480Hrs to start to get burn-in issue using AT&T store demo units as reference.

I use skype and bluetooth headsets alot, so screen shut down may not happen at all until i manually shut off the screen. Moreover, using GPS navigation will definitely cause burn-in problem with static images such as the miles, eta, notification bar, clock, battery indicator, etc.
Android is just not a good OS for Super AMOLED. WP7 on the other hand is for Super AMOLED.
I'd estimate less than 30 minutes total per day (only counts screen on time). So, 480 hrs should let me use my phone for 960 days, or way beyond my tolerance for an *old* phone.
If I'm sitting in a meeting broswing internet or reading news using some apps, almost all of them are full screen and won't necessary have static images on the fixed locations.
Turn the brightness down (I use auto brightness setting) and don't let the screen on for extended period. You will be fine.

I have to agree. The metro color schem (black in most of the screen) is the best way to reduce AMOLED battery usage and lower the potential burn-in risk.

I have both devices and neither or them display image retention. What method or program are you using to test this?
I downloaded a flashlight app on the captivate and on the Focus so I could turn the whole screen white. I also adjusted it to other color,s still see no burned in images.
I've had my Captivate and Focus since day one when they were first released by AT&T.
Go to any AT&T cooperate stores to check out all the burn-in screens. For captivate I use screen test. It cycles from white, black, green, red, blue, and other pallets. I can garauntee you that all Super AMOLED screens are the same given static images and keep the screen turned on such as notification bar, full battery notification, GPS app.
If you don't have any burn-in problems that means you haven't used the screen long enough even you got your devices since launch.

The key here is to keep the screen-on time as short as possible. For normal usage, it will be fine. Will it have burn in 2 or 3 years down the road? Sure, but I probably have to dig it out from the bottom of my drawer to check it out by then. I'd rather enjoy my sharp crispy and colorful SAMOLED for 2 years than worry about burn-in and settle for murky, low contrast and washed out color of the LCD screen for 2 years.
Store demos are the worse case senario.

Very true! But still people really need to beware of their SUPER AMOLED screen. But for gamers...... make sure don't allow a static screen staying on for too long.
Well, I was reading an email yesterday on my focus and noticed that the smiley message icon was like a little ghost in the background. I also noticed the circle/arrow icon. I use orange on black mainly. I moved the tiles around a bit, we'll see if it goes away.

No, it did not go away. It's only visible on white screens, but it is definitely there. I guess I'm going to drop by the at&t store to see if it's a warranty issue, but I highly doubt it. My guess is I'm stuck with it. Since I use the black theme it's not a huge issue, but when I switch to the white theme it looks pretty awful.

Why beware? Image Persistance can happen on any screen that is left running static for long periods of time. In most of the AT&T stores that I have been in the demo units are set to stay up and running for which I can only assume is to attract people. This will cause the image persistance that you are talking about. These phones screens also get used a lot more than your personal cell will.
Use your phone and don't worry about something that may or may not happen. In two years or less you will likely have a new one anyway.
Hilarious!
This reminds me of the times where projector tvs and lately plasma tvs exhibit the same not-suitable-for-gaming problem! LOL
That's one of the reasons I got the Motorola Atrix with its LCD screen!
My previous smartphone was a Nexus One and even though it didn't exhibit ghosting problems, I always tried to use it as little as possible and used the screen on its dimmest setting.
Now I can leave the screen on at full brightness for hours (like for GPS driving for instance) without any remorse!
I have the the imprint of Internet Explorer Mobile's chome burned onto my screen.

They have been trying very hard in the past decade or so. The main problem is the blue channel pixels' life span. Most companies have ditched their effort and move to other technologies. That's the main reason why there is no consumer TVs made of the OLED screens other than the $4000 Sony 14" OLED tv.
Unless there is a scientific breakthrough, this situation will remain for years to come.
Has anyone dealt with Samsung Tech support on this issue I just got off the phone with them and they wanted me to do a Hard reset. I tried to explain that this was a physical issue, but they still wanted to follow their script.
Now they have sent me a label to send it off but want me to remove my SD card. It ismy understanding that this card is bonded to the phone and cannot be used in a replacement phone if they send me one. I am going to call them back ut based on my previous conversation I am not holding out hope that anyone there will know what I am talking about.
There has been a lot said about the screen being dim on this phone, and it's the one and only thing that's holding me back from committing to getting it. Summer's coming and I want to be able to play it outside without having to sit in a dark corner.
I've also read that the auto-brightness feature is mandatory, and that it doesn't work particularly well, so I was wondering if this was the main reason for the reportedly dim screen. My current phone - an AMOLED HTC Desire - is VERY dim with the auto brightness enabled, but thankfully I can turn it off.
For anyone with the phone who is able to test, do you think the screen is bright enough if you cover the light sensor altogether? I'm sure that once the phone is rooted, we'll be able to disable the light sensor altogether, and I'm hoping the screen brightness is purely a software limitation (i.e. fixable) and not a hardware problem (i.e. NOT fixable)
Thanks.
If someone that has theirs already were to check the brightness on boot before the sensors even initialize that might give you a good idea of what it is capable of.
Most android phones i've played with in the past boot at full brightness. Your mileage may varry
Mine arrive tomorrow... dont know until tuesday
I got a slider for the birhgtness, haven't noticed any dimming/brightening automatically, seems just fine to me.
I think that if this problem keeps appearing SE will do something about it, and else the community will
I had mine for a day and sent it back...the auto brightness very temperamental. I would play Gboid emulator (great with new controls btw) and the screen would literally get dim and lighten up constantly every few seconds - under same lighting condition, it became very annoying throughout the day as you end up anticipating it..seems the sensor tries too hard under certain lighting conditions and not having the option to disable auto lighting is just dumb.
The screen is also a terrible fingerprint magnet, and definitely not the best on a cloudy day (Could not test in direct sunlight, this is a rare occurring phenomena here in UK) ...Also dust tends to get into the very fine spacings around the screen.
After an hour of use the phone looked like my kids and dog had played with it for few weeks....Not for me.
But maybe thats just me being spoilt with Nexus S and Ipone4 smudge free, brighter screens.
I dont use the auto-brightness. Ive just manually set it a little lower.

I see what people are complaining about and... really it's not that bad.
I can see where it might get annoying if you're looking for it, but the screen is not going off and on like some people make it out to be. At least mine is not.
I keep mine at 50% brightness and I don't notice a brightness change even slightly. It's bright enough to see indoors easily and not noticeably worse outdoors than any other non-amoled phone I've owned.
from my experience people are making a mountain out of a mole hill, and the auto-brightness can be disabled with custom roms in the future, just live with it in the mean time. That or ask SE for an update that allows you to disable it.

Yep, I keep mine at 60% and don't notice any screen change or anything.
Regarding the fingerprint magnet, you can easily install third party screen-protector to avoid that

Didn't have room to fit the term "differences in technology" in the title. Also an objective pluses and minuses of each technology.
Please don't turn this thread into a bashing of different phones/displays. Lets respect all opinions :victory: I like to know the ins and outs of this stuff for the job .
For instance, I have read that AMOLED can have overly apparent pixels at lower resolutions and that the more often you look at black on the phone, the more battery you will save.
I, personally speaking, tend to enjoy AMOLED screens whenever I upgrade people to S3s vs. lumia 920 or iphones or HTCs.
Lumias lack vibrance to an almost unrealistic point for me. I can certainly understand if someone disagrees, however.
Iphones/ Ipads have great displays, though I find that I have to keep the brightness of them very high to keep viewing enjoyable.
HTCs are the most realistic color wise to me, though personally speaking I enjoy the contrast of AMOLEDS more. I will say, however, the pictures do not do the HTC One display justice. I haven't seen an S4 in person yet, though the HTC One easily trumps its predecessors in vibrance and clarity and is currently my favorite display, even over the S3. We'll see how that works out whenever I see S4.
What are battery saving tips for instance that I could give my customers with all brands for the customers (other than obviously higher brightness = less battery life)? Would it make sense to say that AMOLEDS burn more battery with green because of a greater amount of green sub pixels? Stuff like that.
Thanks in advance everyone!
AMOLEDs over saturate colors by default (although now you can tune it to be closer to real color reproduction if you so wish) which makes more things "pop out". AMOLEDs also do much better with black background, and in fact, I find it the best when watching movies/shows. Their weakness comes a bit with whites which keeps them from a better potential brightness, and they also suffer risk of screen burn-in (Less of a problem as long as you don't keep your screen turned on for hours when you're not using it).
Some battery saving tips:
-Turn off features you're not using. It normally goes without saying but I've met so many people who just want the complete experience who keep everything turned on and then complain because their battery goes to crap even when they're not using said features all that much.
-Beware background running Apps and Apps in general that require constant data checks. It's worth taking a few minutes to identify what these are and whether they're worth keeping and when to disable them.
-Another biggie of course is constant 3G/4G connection. Apps like Tasker and Automagic allow you to avoid constant signal locking with towers that drains your battery when you're not using any of the data.
Those are about the basics. It would be a good opportunity to point out, at least when pitching the Galaxy S4, that since it has a removable battery there's always the option of keeping a spare one that can be popped in when there's no more charge left. This would also happen to be a good time to sell them an extra battery if you keep it stocked. Oh yeah, and please, please, please direct customers towards useful apps. Again, I've met too many people with phones who just go with stock apps and never browse the Play store. There are so many useful apps on there, especially when it comes to managing your phone and taking advantage of all its features.

I tend to recommend two apps along with always restarting/ turning off your phone at least once a day. The apps I recommend are advanced task killer and 1tap cleaner for clearing cache. I recommend them based on their overall simplicity. If you know any simpler/ more effective apps please let me know.
Keep in mind that 95% of customers that come into the store find even connecting to password connected wifi complicated. They are hardly as computer/ UI intuitive as we are concerning apps and phone settings go. If it requires more than three intuitive clicks (not including the click to open it) we generally see it as a no go for recommendations. Lord knows how much we hate how complicated explaining port settings are to explain when people run into issues setting up their emails (Iphone 4/4s's are NOTORIOUS for this.. also if you have a bellsouth email, get a new one. They're plagued with problems) so that they don't have to come into the store every time a glitch occurs and an email becomes unresponsive.
I only understand the screen techs in "layman's terms" if you will, but here goes...
Traditional smartphone screens (HTC, iPhone etc.) are LCDs - liquid crystal displays. There is one big white backlight, and liquid crystals switch on and off to filter out different colors. Each subpixel (red, green, blue) can be adjusted to different levels for each pixel to create every color.
OLED screens, specifically AMOLED from samsung, stand for organic LED. The screen is literally made up of tiny tiny LEDs that are individually turned on or off and adjusted in brightness. This means when you see red, the red subpixels are on, and the blue and green ones are off.
I'm not sure why, but as of now, LCDs work better outdoors. The maximum brightness and reflectivity provide a brighter image on for example the HTC one compared to the S4. On the other hand, AMOLED produces more vibrant colors (I'm sure you heard the phrase "they pop out"), and I don't know why that happens either.
Also on AMOLED, when you see a lack of color (black, for instance), the pixels are OFF. This means that looking at black is exactly the same as when the phone is turned off. That is why you get an infinite contrast ratio; pure black is pure black. This is also why AMOLED gives a better battery life when looking at most images, especially black and dark ones. Conversely, the LCD will use the same power if it is on no matter what it is displaying. If it is displaying anything, it is fully on, as that big backlight covers the entire screen, with the dark pixels blocking it. This means that some light will "bleed" through the black pixels, making them appear slightly lit. The contrast ratio is a factor here, because some screens show less white when they are supposed to be black. When looking at mostly white images (Web browsing, for example), LCDs give better battery life because when you are looking at white on an AMOLED, every single subpixel is on, which consumes a ton of power. For the most part, though, unless you do heavy browsing or have a white-themed phone, AMOLED will generally give a better battery life.
The part about greens is entirely based on other aspects of the display. Most of Samsung's AMOLED displays are in the pentile matrix, which means that instead of three subpixels per pixel (RGB), you get two alternating types of pixels with two subpixels each - RG and BG. While the green pixels are slightly smaller, there are still twice as many, and this layout makes the overall image quality worse than the RGB matrix. In the GS2, Samsung used super AMOLED plus, which changed the pixel layout to RGB. This made the screen look really good, but they switched back to pentile with the GS3 because it is currently not possible to make AMOLED RGB screens with that high of a resolution. However, at 1080p, it is pretty hard for most people to be bothered by the pentile matrix. Most LCDs, aside from those found in Motorola phones for some stupid reason, use RGB.
Hi,
Researching the S5....
I have concerns about screen burn-in over time. Is there any reason to believe that this year's S5 screen is more resistant to this problem?
I've read lots of threads saying that burn-in is a real issue on every other generation. I've had this on a plasma tv and decided that it would bother me if I saw this.
Also, is it true that the screen dims over time more so than an lcd-based screen? For what it's worth, I never felt that an LCD screen loses any appreciable brightness.

Intrinsecally the technology degrades over time, how the S5 will improve that this degradation takes place very slightly until the expected lifetime of the device it's a mystery.
I'd check the S4 forum for details on this, although the S5 is an improvement over the S4 in the display. They have greatly increased the brightness which might help you not noticing the degradation until the device is outdated by modern standards.
As a general advice for any AMOLED never leave a static image over too much time or you'll cause premature burn-in.
I gotta say that the S5 display is greatly improved over the S3 I had, no anomalies whatsoever. The S3 had weird splotches and the quality was inconsistent.
Well I have s1 up to s4.. no burn in..
The secret is dont leave static image for long time.. for example I use 24 hour time to avoid AM PM burn in..

I suggest the following:
- Research Samsung's AMOLED display technology SPECIFICALLY on the S5. As in, go to Samsung.com and find a pdf or listing of the display's granular details for it's specifications.
- As a result of Samsung's implementation of their AMOLED displays (this can only have been improved for the S5), PenTile screens contain twice as many green subpixels as reds and blues, and since it’s the blue subpixels that degrade most quickly, PenTile displays are less susceptible to screen burn than the RGB type of AMOLED screens. HOWEVER, they are still susceptible to burn-in, although there are ways to prevent it from becoming permanent.
Burn-In Risks
Charging - Android phones have the option of keeping the screen on while charging. Don't do that, it's silly.
Developing (Stay Awake option) - I use Stay Awake when I'm debugging apps on my devices, but I also manually turn off the screen during periods of time when I'm not sending an ANT build to the phone or debugging on a device from any IDE rather than an emulator.
Navigation apps - these apps are probably the ones that people are least likely to realize can be burn-in culprits.
Other apps that remain on during docked use (internet radio, anything that will keep the screen on)
Lessening degradation
So, when I get my hands on the detailed specifications sheet of the AMOLED display on the S5 and presumably purchase the S5 when I know for a fact I can unlock the bootloader permanently, I am going to see if they are using PenTile screens (or whatever technology they are using) so that I can manually create a screensaver/app that runs and displays every color on each pixel for the corresponding amount of time relative to each color's known degradation. The "O" in AMOLED represents "Organic" and that's why the chemicals/materials they use degrade over time.
You can bet that Samsung will continue to improve the way their display operates in each of their future software updates. I'll tell you this: A LOT OF people own the Samsung S3 - I believe more use the S3 than the S4 or at the very least, similar in # being used. AND the S5 is already available.
I listed most of that to inform people that aren't otherwise informed, but Samsung has become a Behemoth in smartphone hardware and I guarantee they will do everything possible to compete with Apple and surpass them. Will they? I hope they do. Then I hope Apple surpasses Samsung, and have them go back and forth so that the consumer ends up benefiting the most. Competition in business is often (not always) what forces business to retain customers and acquire new ones, especially anyone switching from iOS to Android and vice versa.
If you're really that worried (rightfully so, given the price of the phone), look at your warranty documentation and call Samsung and ask them directly; though, unless you get a confident response backed by verifiable facts, call again at a different time. I always do this whenever I call any company because you never know where your call will get routed, who is picking up, how competent they are, etc.
Also, see if there's an extended warranty program you can get within whatever purchase window they have (LG for example, offers it for some phones 30 days within purchasing/registering the phone). Motorola offers it during checkout on their website. I have yet to check Samsung because I'm mainly focused on the status of the 32GB model and the bootloader's status in terms of remaining unlocked or not. Hope that helps even a little.
Cheers,
Justin
Doesn't seem like the clock or battery icon move around like Always On mode. Will this eventually cause burn in?

No. Amoled displays don't suffer from that. Even high quality LCD displays like found on the iPhone will have a hard time causing burn in.

I doubt it, the brightness would be low enough to minimize the risk of burn-in.
I don't think it would. I have mine set to only stay on from 1AM until 5AM (the hours I'm most likely to wake up in the middle of the night and want to see the time.)
I don't think 4 hours is enough to cause burn in being how the pixels are lit up very dim when using the night clock.

The pixels are stilll active though, shortening their "life". Will you notice any burn in or difference in screen quality in that area within a month or six? Probably not, but it'll burn in (or, leave a mark if you want) no matter what after 24+ months. AMOLED is a tricky technology, so I personally stay away from "AMOLED black" themes and whatnot. Why? The black areas are turned off, while the colored/lightened pixels are lit up. The areas that are "off" will have a longer "pixel life" than the ones most used, so it'll make a sort of "ghosting" effect after a while (2 years+). Using a theme or whatever that's "even", i.e not on and off at different places will give me an even "burn out".
I have no idea how good the EDGE's panel is though, so this is pretty much pure speculation, with some facts mixed in!
At first I was also worried that the pixels don't change position, but having it on for a week, I think it's too dark to cause a burn-in.
The Always-On clock looks like it'll burn in more because it's bright even though it moves around every couple minutes.
I use a black background. I don't think it'll cause uneven wear. Every time I use a web browser, the background is mostly white. I think that's enough to evenly burn in the screen. I usually keep the screen little dimmer than normal to avoid burn in., but I'm not afraid of ramping up the brightness when I'm outside under the sun or reviewing photos.
One thing I don't like about the night clock is that it shows the alarm that's couple days out. I think Samsung really need to fix this as this is obviously a bug, or they didn't test it enough.

Everything is pure speculation regarding the AMOLED panel around here, so we won't really know anything concrete until something happens, or someone gets a nasty burn-in. I doubt anyone will get a nasty burn-in though, but I guess someone will get some burn-in down the road, but that's pretty much expected.
I have a Galaxy Note (first gen.) that I used for about 18 months before getting a new device, and I've borrowed it to my mom. I checked it out again this week after not checking it out for about two years, and the display looks like ****, but it doesn't look more **** as it did the day I gave it to her, so it's "bad" if I'm trying to edit some photos, but it's not catastrophically bad at all. The only place it's burnt in is the statusbar, which is black on pre-lollipop versions if I remember correctly.
Hi clever people
So I'm a bit confused. I found this thread because I was afraid of a burn-in caused by the night clock too.
And I won't use it. But how about the always on display, then - by using that, is there a risk of shortening the life of the pixels? In that case, I'd just turn it off. But if not, well, then it's a neat feature
Well, I have set night clock every night, It doesn't burn the AMOLED screen. It's completely safe. Try it on your own, no risk They prevent burn in, because of brightness help keep prevent burn-in.

Thanks. I was more curious, though, as to how the Always on Display feature might affect pixels and the screen lifetime too, and thus, if it'd be better to not use this feature

No. Amoled displays don't suffer from that. Even high quality LCD displays like found on the iPhone will have a hard time causing burn in.

False. AMOLEDS suffer burn in, and LCDs will rarely ever experience it.

No offense that is the most stupid reason I've heard not to use dark/black themes. White themes ARE MUCH MORE LIKELY TO CAUSE BURN IN, PERIOD. You reduce burn in by reducing energy consumption and pixel usage.
