Question: Screen Burn-in
Is it possible or probable that the Galaxy S phone line (Super Amoled), and more specifically the Epic 4G can suffer from screen burn-in? I ask, because when I have the Epic 4G in the dock, the screen does not go blank at all. Then when I do blank it before going to bed, I return in the morning to find the pop-up message indicating the battery is fully charged and to remove the device from the cradle. I don't know how long it is on like that, but am concerned about screen burn-in on this device. What are your thoughts?

I had the desktop dock app and it keeps the current time on the screen in large type, and I noticed today reading an email that those numbers are in fact burnt into the screen... Looks like I'm going to exchange my phone at sprint and hope I don't get a refurb with the same problem.

Yes, the Epic is susceptible to screen burn-in. See:
Anybody wanna see the image burnt in my screen? - PPCGeeks
It is advised to install a screen-saver if the screen is configured to stay on during an extended period of time.

Well if you read the thread it doesn't appear to be "burn in" with what that guy said. Makes sense that it's the led burning out.
I didn't take it would do that so soon. If he's right it's only noticeable because the background of the desktop dock app is black and not using any leds.

A standard lcd screen uses a backlight behind the pixel cells. The cells don't emit any light themselves. Hence they are not prone to burn in because the cells don't get weaker over time with use.
In oled screens, much like plasma screens, each cell is emitting its own light. There is no backlight. Each cell gets slightly dimmer with extended use. So it makes sense that they are susceptible to burn in.

Unfortunately, this seems to be a common problem with all AMOLED technology. Apparently that beautiful picture comes at a cost. I love the Super AMOLED display, as the picture is highly reminiscent of my Pioneer Kuro Plasma, but trying to avoid burn-in on a smartphone is IMPOSSIBLE. I was under the impression that AMOLED technology impervious to burn-in and instead only suffered from image retention, but apparently it's permanent.
I checked my phone and I have mild burn-in, only at the task bar at the very top of the screen. See early adopters of the Nexus One to hear more about AMOLED burn-in. With that said, the picture quality is still unmatched.

I knew about AMOLED burn-in quite a while back because Nexus One users were reporting screen burn-in. After researching Super AMOLED, I knew it had the possibility of burn-in too. I read the thread, and it appears that it may not be burn-in, but either way, the guy looks like he's exchanging it.

OLED is definitely susceptible to burn in. I saw some pretty bad burn in on a Fascinate at the Verizon store yesterday. The icons on the bottom were very clearly visible when that area had a white background (like a web page). The Epic would be susceptible to the same thing.
Granted, store models may spend more time turned on than an average phone would. Still, that display unit has to be 2 months old or less, since it only came out on VZW at the start of Sept.

Isn't burn-in the reason for having black top bar (which I prefer) instead of stock Android white/grey color?
If Nexus 2 (or S) comes with stock Android with white status bar on top, screen burn-in (in addition to battery drain) will be a big issue.

this thread may add to your discussion
Its not as much burning in as it is the molecules inside have died more than the others and therefor have colorshifted and that is what you are seeing color shift due to shortened life

Maybe the dock app, but certainly not burn in.

Again, I have no doubt that screen burn-in happens. But I've been around enough IT to see a lot of cases of screen burn-in, and none of them, and I mean none of them are ever as defined as that. That's why I'm not buying that particular picture. Burn in occurs after many, many hundreds of hours of the same pixels being used. 1's and 0's are undoubtedly the most used numbers for time, but not in that exact order of "10:00".

I got a replacement refurb Moment (AMOLED screen too) and it had the status bar across the top burnt in badly. That led to me getting an Intercept replacement, which in turn directly led to me upgrading to the Epic (oh my gawd the Intercept sucks...).

Re: Question: Screen Burn-in
This is a picture of the burn in. when i have it on the dock, that is the only way i can see if i get new messages. other than checking the phone constantly. lower right hand corner toy can see the blurred clock. it can only be seen during a bright screen.
