Since our Epics have Super AMOLED screen being organic in nature I know certian lasers will mess up the screen. The blue one being the worst but what about the red ones like a store's scanner?
Here is a news article about Starbuck's idea of paying coffee with your phone:

Will it mess up our phone's screen?

No it will not. you'd need like a week of nonstop laser being directed at the screen. Besides, the Sun is far more powerful.
If they are going to have a barcode reader it will most likely be a camera and not a lazer...I dont think lazers can even read off a screen...your screen emits light...you cant pick that up with a red lazer...

Umm...I don't want to go all physics on you, but anything you can see with your eyes is emitting or reflecting light, except black, which is an absence of light (including the black on your screen). Soo..yeah. Not being a **** lol.

it makes a big difference between emitting light and reflecting light..The fact that its emitting light eliminates the purpose of using a red lazer altogether..

Actually, you kinda are being a ****, and saying that you aren't doesn't magically negate that fact. Also, the black on our screens is NOT a complete absence of light - turn your phone off (shut down, not screen lock) in a completely dark room to see just how much light comes from the screen (you can try loading an all-black image file as well). And I don't want to get all physics on you, but the screen would refract the laser, which may or may not cause problems. But any scratch on the screen would interfere, and Starbucks can't predict where or how people will scratch their phones, or what type of screen protector they might use, so that method would be too unreliable to work with the general public

Just for the point of clarity, an AMOLED screen does indeed use NO light to represent black. AMOLED displays do not use a backlight so black is "rendered" by simply not turning on any color for the pixel.

Wow. Way to troll my post. I'm sorry but that was completely unnecessary.
Indeed the glass and scratches can present refraction problems, but that is why it must be done nearly face on, and why barcodes are so tall, because physical scratches on a barcode can have the same consequence of a failure to read.
Also...I never argued it was perfect. In fact, I agree that the glass alone presents an issue in reliability.
But I never mentioned the glass, because that was not the point I was making. If you read my post, and use some basic intuition, you'll see that I was merely pointing out that it is incorrect to think that light emitting from my screen is different than light reflecting off your bar code. He had, in effect, argued the opposite previously.
And you really mistook the voice of my post. My preamble was cautionary because I didn't want to sound like a, well, ****. And my conclusion was simply reaffirming that. If you reread my post with a more hesitant voice you'll understand how I wanted it to sound.
Then again, it's not like we're talking face-to-face. I can't really blame you for misinterpreting like that, because automatically placing an insulting voice in there would be your problem, not mine.

LOL.... Plus one for that joke!
Reading through the posts some interesting points. However, this isn't about scanner NOT being able to read the bar codes on our Epic screens. It's about the possible damage caused by a narrow beam of light enegry for any length of time.
I know regular LCD screens aren't affected by this but AMOLED is sensitive to UV light such as the sun.
Here is something I saw on Wiki:
"UV sensitivity: OLED displays can be damaged by prolonged exposure to UV light. The most pronounced example of this can be seen with a near UV laser (such as a Bluray pointer) and can damage the display almost instantly with more than 20 mW leading to dim or dead spots where the beam is focused. This is usually avoided by installing a UV blocking filter over the panel and this can easily be seen as a clear plastic layer on the glass. Removal of this filter can lead to severe damage and an unusable display after only a few months of room light exposure."
I have to wonder just how strong can the UV fliter on our phones protect the display? So far my normal usage on the phone the display looks fine. Then again I made sure it wasn't left in the sun too long, maybe like a few seconds.

Hi everyone so I've had my evo for about 2 weeks now I slightly see some light were some people have had real big issues should I be worried...i mean you really have to be looking for it..i didn't even know wheee thee light was coming through.also at the bottom of the screen if you tilt the phone I can see the light from the menu buttons is this normal?

I think its normal, mine does it. I watched unboxing and reviews of EVOs on YouTube and it was pointed on on them too. I have a rubber around mine so the light leak is covered. I can also see the light leds if I turn the phone and look down from the screen. Its an obvious design flaw, im surprised they let it go like that.
Normal.
I was about to go to sprint store for a exchange and also saw YouTube ones shown had same problems. I guess It's normal for HTC products...
Just hope dust going into it end up inside the lcd.
Doesn't bother me...
Yep I have some light leakage too on the bottom. It's normal...

Lol neither do I. It dosent bother me.
So, I stumbled across something really cool (quite) a few minutes ago: apparently our devices really can power a few pixels selectively. In my accidental confirmation of Samsung's claim, I was able to get one of NoLED's notification icons to show on the screen without lighting up the rest of the black area for literally a split second.
Here's how:
1. You will need the app "NoLED" in order to continue. In the NoLED settings, make sure you have the icon for sms activated as well as the proximity sensor. My sms icon is set to a lime green, but I doubt that will affect this "test."
2. Send yourself a text message either from your own phone or from some other sms capable device. If sending it to yourself from your own phone, quickly lock the device using the power button after pushing send.
3. Allow NoLED to start flashing around the icon for sms. Wait roughly 5 seconds for the proximity sensor to activate.
4. For steps 4 and 5, it would be wise to be in a completely dark room to be able to more easily tell the difference between the true black and the lit black. With the proximity sensor now active, place your finger over it. The screen should turn off.
5. Now, upon removing your finger pay close attention to the icon that will appear. The icon will show up a couple of milliseconds before the rest of the screen activates.
6. Repeat steps 4 and 5 if needed to witness the true black.
This is proof that our SAMOLED screens can display true black.
I am not a developer so I have no idea how to act upon this find to, if possible, adjust settings in the our software to allow true black.
If you happen to know someone who is capable of modifying the kernels or ROMs for our devices to allow this behavior, then by all means have them follow the above steps to see the proof.
Though I hope this minor find can give someone the inspiration and/or start place needed to make these adjustments, I realize this is but a pebble in a world of boulders. Therefore, I remain skeptical and strongly advise others not to get your hopes up.
If anything, it is at least nice to see that Samsung wasn't just lying about the capabilities of SAMOLED screens, but also makes one wonder why they don't allow true black from the start.
Now, time to hit the hay.
Goodnight all.

When i power the device off in a dark room, at the end of the power off cycle I get a black screen that isn't black like the other black screens when the phone is on. It looks like it's glowing in the dark or some junk, and you can see a weird pattern like something smudged across the screen.
Is this the type of thing you're talking about? That our devices, when showing black, are actually working to show that black and not just "turning the pixel off" er whatever?

Yes, if I'm understanding you correctly that is what I'm talking about. That glowing, almost grey effect shouldn't need to occur in order to show black. I hope it is something that can be hacked, but I don't know.

I guess this makes me lucky to have 1 pixel stuck on blue. I can easily see the screen turn off in almost any lighting condition.
Couldn't it be that what you're seeing is some kind of residual charge left at power off or some pixels that change states at slightly different rates? I've seen it too and it seems to be a different pattern every time. Also, some of the forums regarding screen burn have talked about samoled break-in so maybe that has an impact as well. Can't factor out power supply leakage either, I guess.

It is true all of those things could be probable, but in order to prove that the pixels aren't turning off you could disable the lock and screen dimming functions with an app and display a black image. Then in low light conditions you could easily see the blacks are actually a very dark shade of grey. If the pixels were turning off the image would over time obtain deeper blacks as the residual charge runs out.
I, and many others, suspect the phones are programmed to not turn off the pixels. Only question is, why? The only thing this type of test wouldn't be able to prove or disprove is power supply leakage.

Or you can go and download Screen Test and get to the black screen part of the test. It is so hard to notice, but blacks are ever so slightly lighter than if you were to turn the screen off, but it is really hard to catch. Either way, they trump any LCD black levels. They even make my Panny plasma look bad

Well I guess that isn't too bad, hopefully it isn't a sign of things to come. Back when I had my Storm 1, I had a red stuck pixel. It wasn't too bad either until it started spreading a few months later. That's okay though, I was one of the lucky ones who got a Storm 2 as a replacement from Verizon. If you havent, you should definitely try that app mentioned above though.

The thing is I can only really see this during a grey-ish screen when one of my games is launching. I also notice that it isn't the same image each time, which leads me to wonder if it isn't less a permanent burn in and more of a temporary "ghosting" after effect.
Well I"l give it time to see if its "ghosting" or real burn in.

Maybe it's cause the screen is so bright it burns into your retinas.
If you stare at the screen for 30 seconds then stare at a black wall in your house and watch 8:00pm show up
Actually, it isn't "technically" burn in, but it sorta is (mine does it too). I'll explain.
First, grab "Screen Test" from the market. It cycles through full screen black, white, red, green, and blue (I do video AV work) On white (2nd after black) you will see the clock and am/pm if you're like me and cycle all day through 3 batteries. I use alarm clock plus but it has a screensaver at night, so that's no issue.
You will ALSO notice going through the colors that red and green are fine, blue is burned OUT (not in). See the wikipedia article for the explanation, but basically blue wears out first because of the organic compound it's based on. This is why they don't have amoled tv's yet (that and size). Honestly, I dont't think it'll ever get terrible before I'm ready to upgrade, although as a video engineer I certainly see it every time now that I'm aware of it. But really, I still like it better than lcd. And let's be honest, most people that are on here that are smart enough to notice probably are too gadget-addicted to keep the device long enough for it to be anything more than a "Hey, is that a clock I can barely see in that corner that just happens to be all white right now?"
What IS funny (and really cool I think) is the fix, is gingerbread ;P no, seriously, hear me out, the clock is green isn't it? Green lasts much longer than blue, (red lasts longer than green, but who wants a red clock?) So you wouldn't be using the blue subpixels at all. Of course that won't REVERSE the damage but it will slow/stop it from continuing.
(And yes, I do realize simple theming would also accomplish this )

I was opening my phone up this afternoon, so I had my magnifier on so I could see (my eyes aren't quite what they used to be). I just happened to have a bible app with the red letters and blue Strong's concordance up, and when I looked at it through the magnifier, it had a 3D effect. The red was "higher" than the blue. I called my wife and mother in law over to make sure I wasn't imagining this, and they saw it too. When I took the phone out from under the magnifier, the 3D effect went away (obviously).
I played around with other colors, and it seems like the blues and greens are the furthest "back", and the reds, yellows, and oranges are furthest "forward". White seems to be somewhere in the middle.
I almost feel like bringing the magnifier around with me just too see the 3D stuff, but the glass and round fluorescent bulb together are about 10" in diameter, and a bit hard to stuff in my pocket.
Anyone else see this effect? Is this how the 3D phones work?
That's quite the strange effect, but nope, that's not how 3d phones work. As far as I know they use Parallax barrier technology. here's a quote:
"The LG Optimus 3D (and the Nintendo 3DS for that matter) uses the parallax barrier technology. Parallax might sound scary, but simply put it is the effect of seeing closer objects bigger and more distant ones – smaller. What matters most is the barrier however. It is just what you would imagine – a vertical slit plate on top of the traditional screen that blocks part of the image for each eye. The technology is somewhat limited to smaller screens, but yields good results without the geekines of wearing glasses" (www[dot]phonearena[dot]com/news/3D-How-does-it-work_id16950)
I see this all the time with my glasses. I think there is a slight prism effect where the angle of the different light frequencies (colors) is slightly changed by the lens. I also see it at night when there are bright blue or red neon signs.

It was quite an effect, the difference between the blue and the red was probably about 1/8 inch, and very obvious. I played around a little, and there is a definite difference between the blue & red. Looking at all my app icons was quite impressive.

Omg! What I say? We all know these screens are not 3d. Poor ol goon needs to see a eye doctor. He's probable walking around this world face planting into trees. Poor ol lizard, you guys aren't helping him by lying to him that we do have 3d screens. FOR SHAME!

Does anyone else have a magnifying glass that they could see if it does the same thing? Mine is the one with the arm that can be moved around, round fluorescent tube with the glass in the middle.
BTW, my eyes are 20/15 and 20/10, so I actually see better than average, but when I want to see tiny stuff, that's when I get the magnifier out.
Dear god! What the heck you doing rolling around on a hoover round with magnifying glasses! Creepy ol man you!

I've been seeing that "3d" effect when wearing glasses, since CRT days. Must be the way clear ploycarb affects the light. In real life, I can also see slight red/blue edges, depending on the light.

I was opening my phone up this afternoon, so I had my magnifier on so I could see (my eyes aren't quite what they used to be). I just happened to have a bible app with the red letters and blue Strong's concordance up, and when I looked at it through the magnifier, it had a 3D effect. The red was "higher" than the blue. I called my wife and mother in law over to make sure I wasn't imagining this, and they saw it too. When I took the phone out from under the magnifier, the 3D effect went away (obviously).
I played around with other colors, and it seems like the blues and greens are the furthest "back", and the reds, yellows, and oranges are furthest "forward". White seems to be somewhere in the middle.
I almost feel like bringing the magnifier around with me just too see the 3D stuff, but the glass and round fluorescent bulb together are about 10" in diameter, and a bit hard to stuff in my pocket.
Anyone else see this effect? Is this how the 3D phones work?

I myself being 30 have seen something to that effect. I believe it has something to do with the way the led's are layed out on the amoled screen. If you ever have an average size multi color led you'll notice that depending on the color of the light coming from the led, it is not always centered, or in the same area for that matter. I believe the same effect happens with the amoled just at a much smaller aspect. I've also noticed it on a scrolling led banner. When red and blue are close to eachother, one looks higher than the other

Hey guys I'm sue most if not all our you know about the black ink marks with the SGS III. I was wondering if it would be a good idea to take the phone back and get a new one but now I'm not sure because I hear that almost all the SGS III handsets have them. How many of you have taken yours back and was it worth it?

You can only see them when it's dark. At first I didn't think it would be a big deal but last night I opened my message app and I could clearly see them.
Edit: has to be a black background.

I have none at all. I used the texting app and andftp.
I didn't have any on mine, though waiting now on my new ordered phone.
Hmm well I'm going to be exchanging mine in a few days.

I noticed a couple on mine, but they really are only noticeable in total darkness on a black background. If they get worse I'll consider getting it replaced, but its such a minor issue, it doesn't seem worth the hassle of a replacement.
The screen is amazing compared to my OG Epic.
They are "normal" for amoled screens. Ive had about 12 razr/razr maxx and everyone had it to a certain extent. They never got worse. As long as you dont have the black line running top to bottom you should be fine.

Try using this background turn off the lights and see if you can spot the splotches.

Here's how to test:
1) Download Display Tester, Go to Colors, then Dead Pixel.
2) Swipe the screen to the black color Page.
3) Go into a dark closet and look for anything weird on the screen.
I'm pretty sure that everyone who posted here will not have a perfect screen.
I have a couple but never notice them unless the screen is super dark...not too worried unless I notice them under normal conditions.
Here's an idea; if you have to test for something under extremely particular circumstances and don't notice it otherwise maybe you shouldn't go looking for a reason to make yourself unhappy.
Just a thought.
If you stand on a chair holding the phone at 37 degree angle while watching a specific Nickelback video and get a weird tint...don't do it?

I downloaded display tester and didn't see anything weird at all on my phone's screen. All the colors were smooth and even with no spotting.

I noticed a few splotches on day one, but just now after looking at the almost black test image I couldn't see anything at any angle or lighting conditions. Is it possible that this goes away over some time?

If you ever watch a dark movie, you will notice it. It can be irritating to say the least.

I wasn't looking for them. I didn't even know they existed. I actually noticed them one night when I was texting. It sucks that some have them and some don't... I would like to be one of the few that doesn't if you know what I mean
Sent from my SPH-L710 using xda premium
Yeah, I can definitely understand being irritated if you see it during normal use, it just seems like some people (big thread on this in the international section too) go looking for it. Personally unless if actually seen it during my normal usage I'd never go looking for some flaw that I'd then always know was there.
That was what I was getting at, just to clarify.
