I went to the AT&T store today and was comparing the iphone to the samsung focus. i really want to get a windows phone but waiting for the lumia 900 to come. i noticed that the focus has severe burn-in on the screen. you can see the squares of the windows home screen ghosted when loading a webpage with a solid color like sometimesredsometimesblue.com - which i use to compare colors on devices.

for me the iphone is so washed out i just can't bare it. but the alternative seems to be a possible burn prone screen.
 
Burnin is possible but usually not a problem if your screen isn't on all the time on the same image (i.e., in a showcase).

Overall the only thing that might be a problem is a white status bar but from Gingerbread 2.3 on, Android has a black status bar that can't burn in.
 
the amoled screens are by far the best from what I've seen. I haven't had any burn-in issues and neither has my brother. Most of the time your screen is not on anyway and when it is you are changing what's being displayed. I would imagine it would have to be on a while for that to be an issue on the same thing
 
It's not really an issue unless you leave it plugged in with the brightness all the way up and the screen on with a static image/screen. Display models are way more prone to this than your average user's device.
 
I have experienced burn-in with AMOLED, primarily on the top status bar. It happened even though I've used HTC Sense where the status bar has always been dark. I used to run full brightness because I like AMOLED that way. For the sake of headaches and battery life, I dimmed it down after a year or so. That's when I first noticed the effect.

When I saw the burn-in, I used one of these screen repairing tools and it actually reduced the effect quite significantly. Still, I can see it. I would still choose an AMOLED display over anything else.
 
I've had my Captivate for almost two years now, and even with me keeping the screen on while charging, I haven't experienced any burn-in.

I'm one of the lucky ones?
 
I picked up my Samsung Focus on launch-day (so the SAMOLED screen has seen a decent amount of usage), and I've gotta say, burn-in isn't an issue in real-world usage.

The display units in the AT&T store are probably always-on in demo mode. Being on for ~16 hours a day on (mostly) the same screen is pretty far off from how most of us use our phones :p
 
I've seen temporary image retention on my Nexus S, but never any burn-in. I wouldn't worry about it at all. The Lumia 900 has a non-pentile amoled so it should be great.

Not surprising, since Samsung uses a similar screen size and resolution on their Galaxy S2 phones (4.3 inches, 480*800 WVGA)

The banding on the nexus is caused by a poor a gamma adjustment algorithm, not the pentile arrangement. Its fixable by a firmware update.

are you sure? it seems like its a physical thing between the glass/screen. maybe what im seeing is not called banding.

said to be with all amoled's. would be awesome if i could get a fix for it!
 
This is what i think of when I hear "banding" (specifically, color banding):

Notice the bands of color in the blue sky? It's baked into the image here, but screens that are unable to produce smooth color transitions will show a similar effect on any image you display on them.
 
ah, ^ thats not what i mean then, sorry :S.

physical lines that are only noticable on low brightness on full white/gray pages is what i have.

Yeah, I don't know why everyone calls it "banding". I think a more accurate term is "ghosting" or "burn-in" even though it's just very temporary burn-in.

Some screen have panel banding. Many Samsung LCD TV have this flaw. You can see vertical bands when the screen is displaying uniform color, say a football pitch. Easiest to see when the screen is displaying a uniform grey test image.

I also saw image retention on an AMOLED screen. Surprisingly it is on the newer Samsung Galaxy Note demo unit in store. I search this issue and came across this thread . The Galaxy Note may be a demo unit, but it is only recently released. It couldn't be running that long. I can see the shadowy retention of the icons on the bottom of the screen.

Yeah, I know what banding is and what you described it to be has already been demonstrated in Unknown-One's post above. I haven't seen either of my two Galaxy Nexus phones have any issues with banding.

The ghosting/image retention issue has definitely been noticeable on both phones though. Usually only while brightness is low though. I wouldn't be surprised if the Note exemplified the same ghosting since it's the exact type of display as the Galaxy Nexus, just slightly higher resolution (1280x720 vs 1280x800). It doesn't last long enough to be distracting or depreciate from the experience of using the phone though, IMO. It's not noticeable during video at all regardless of brightness too, so that helps out a lot.
 
leave any LCD on long enough on the same screen and it will get burn-in........we have a samsung that has been displaying the same screen for 4 years and it is burnt up pretty good.

Actually you are still misunderstanding it. There are two kind of banding. Unknown-One post is describing "color banding". Me and DF-1 is talking about a different kind of banding. Let's just call it "vertical banding". Some people refer to it as Dirty Screen Effect.

"Color banding" as Unknown-One described is due to the screen being unable to display a smooth gradient of color. For example, this is noticeable on gradient gray scale test pattern.

"Vertical banding" that DF-1 and me is talking about is due to the screen being unable to display solid color uniformly. For example, this is noticeable on solid white or solid grey image.

They are not the same and they happened for different reasons too.

Concerning the Note vs Nexus screen... According to gsmarena , the maximum brightness on the Note is 73% higher than the Nexus. Maybe this contributes to the image retention ?

Ahh, gotcha. Thanks for clarifying that. I had never heard of a different type of banding other than color banding. I definitely notice it more on white and grey backgrounds than any other colors. I play Wordfeud a lot and it has a grey theme to it and I always see my letters burned into places for a few seconds when I move them.
 
My Epic4G shows neither form of banding or ghosting. Not sure wtf yall are talking about. No burn in either. Have had the phone for 1.5 years.
 
So firstly, I'm using a Samsung Galaxy Nexus with the Pentile SAMOLED screen. I love the screen. Until this morning...

My phone decided to reboot itself while I was sleeping last night, and it hung up on the boot animation for the ROM I'm using (GummyNex 0.9.0 for CDMA/LTE). It must have happened earlier in the night, because now there's a faint "g" from the boot-up "animation" (mostly a still image with a progress bar on the bottom... white on full brightness) burned into my screen.

Someone told me to keep the screen off to let it rest for a bit. Does anyone know if there's any remedies for this?
 
Take that image, invert the colors, and leave it chilling for just as long. Vwala, uniform burn.
