Do you have such stains? I hear this is normal among AMOLEDs.
welcome to mass produced (aka economically viable) OLEDs...
Some patterning or colour patching is inevitable even from new. Blue or Grey backgrounds tend to show patches up more. Very low brightness shows a greenish cast on the left of the screen too.
It took more than a decade before LCDs could be produced in volume with a very low dead pixel yield.
We have a dozen GS2s at work and they all have minor screen issues. From new. They do get worse or even change position over time (many months) as the pixel level elements shift in luminosity.
Also note that if the phone is warm, the effect lessens.

Thank God I don't have dead pixels. At least this patch I got is visible only on dark-gray / medium-light (so-to-say, idk) brown. I'd rather have that than dead pixels .
Actually, if I start Screen Test, the patch is visible on ALL colors. On blue/red/green, it is less visible. On white, it is most visible. Also, when displaying full whites, the color is not homogeneous. Vertical and horizontal lines seem to be present ALL ACROSS the screen. These lines are visible on white, yellow and such colors.
At least I don't have ghosting effect and the whites are actually white, not yellow - as it was on Gingerbread (yeah, software problem, eh?).
So... the patch appeared to have vanished after running the fix (which rapidly ****s four colors) for half an hour, because the screen was a bit warmer... and as it cooled down, the patch has shown its face again. Oh well...
the galaxy note and s2 super amoled screens are prone to burn ins, very common, you need to eliminate risks involved.
Turn off auto brightness, lower the brightness level, shorten the time youre screen stays awake for, and if youre using themes, avid the blue themed ics ones, although they look nice, the blue themes are one of the biggest culprits of the burn in issue and before ya know it youve got a battery image burnt in.
i notice it looks like you have a blue theme or something, my mate had same issue, what can ya do, its a pain and well probably all suffer it, whereas htcs dont have the issue, they just suffer dead pixels a lot, but hey, id soone have slight burn in than dead pixels i guess

F*** !
MIUI uses white & orange. Are those colors dangerous, too?
I mean... what colors should I avoid the most? Besides blue - I get it, it's bad (again, F***).
Anything that turns the RGB elements hard on (!). So high brightness only and white is worst as this is RGB full on, then pure red, pure blue, pure green. Cyan, yellow and magenta are less risky. In theory.
In practice and the real world, just keep the brightness down a little and you'll get years out of it. And save battery - the screen is THE major power consumer...

+1 absolutely right, follow these simple rules and all should be good.
White requires all three elements (RGB), right? Blue = B. Which one should I stick to...? My logics tell me blue, but I hear AMOLED's blue color is so pure because of a compound from algae (rofl) and it wears off more quickly (if any of that makes sense).
Cyan, magenta, yellow... Yeah, I don't have that on AOKP, lol. And neither would I want a yellow theme. Magenta would be nice, though.
RGB... hell, those are the primary colors. How about we use black, with polarised glasses? That'd be a good deal, since I wear glasses, lol.
Seriously, guys, what do YOU do to make sure the screen doesn't get damaged over time? Don't tell me you're using a yellow-black theme. And setting the screen brightness to 50% or more is required outdoors, so...
-----
I just went to a showroom today. Seen the Galaxy Nexus there. It's on, with the brightness set to maximum, 12 hours a day, and it's been like that ever since they put it there - more than 3 months. Seeing anything strange here?
well, as a rule i dont have wallpapers that have bright vibrant colours, i find it annoying and painful on the eyes, and if you have shortcuts on the homescreen it gets to looking messy, so i stick with dark colours, to be honest most of my wallpapers are black or almost black and my brightness is set at around 20%, and i dont struggle to see it outside in sunlight or anything, but this is just my prefernce, im sure everyone has different tastes, i think you should just enjoy your phone and use it how you wish, but try to avoid having it too bright, it should be ok.

I'll stick to the stock AOKP theme (blue, that is); but I will be careful not to raise the brightness above the point of 50%. And even if I do, I guess setting it to the maximum point for a few minutes (when the sunlight is very strong) wouldn't hurt...
Oh and mind archiving your black and dark wallpapers and sending them over to me? Please (I'm always happy to pile up such wallpapers)
Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

It's not backlit is the point.
Correct me if im wrong here but amoled is, by design, not backlit.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )

It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
So i just bought an S3 and there is a pixel on the edge of the screen that is coloured bright on low brightness and coloured black on high brightness.
I did the *#0*# test and while it was not visible on red and blue background, it was visible on green background as a black dot.
I mean if it was a dead pixel, it should always appear as a black dot instead of appearing white on low birghtness right?
It doesn't look like a dead pixel, but it might be the green subpixel that does not work properly (although this does not explain the low/high brightness stuff). I remember that I had a stucked pixel on an old lcd and I used a java program to unstuck it. After a search I found that are equivalents for android, like https://play.google.com/store/apps/details?id=com.htc.chris.blackspotdetect&hl=en . Take this solution with a grain of salt, it doesn't always work and also bear in mind that the screen has a lifetime, do not overuse it.
thanks for your comment. i'll just try to be less ocd about that point on screen.
I know this has been brought up before but I am curious if the light bleeding and very dark screen is an issue with just some of the devices? My light bleeding looks horrible and can't stand looking at it in the dark. And during the day time it dims so dark I can't even see if I have a notification. Thoughts?
The light bleed is totally normal. This is an LCD screen and it uses backlight technology. There will be bleed when one part of the screen is lit and the rest is not. The reason its hard to read the 2nd screen out in the sun is because the 2nd screen dims to the lowest possible level to preserve battery life while it is on. It will brighten up if you actually wake the screen. I agree the 2nd screen doesn't look great at night but that is the trade off you get going with LCD. AMOLED wouldn't have that issue but AMOLED screens tend to burn in. Pick your poison.

I understand that but the main reason for getting this device was hopes to see if I have a notification by simply glancing at the 2nd screen. It's so dim I can barely even read it. At this point I wish I just had a flashing led.

I don't have the phone but based on other peoples experiences it sounds like you have a defective phone. The second display should be easily read. People seem to love it.

Plus their reds look like oranges.
I'm just noticing that the left edge of the 2nd screen, next to the front cams, is a lil brighter than the whole 2nd screen, in the upper corner. Im assuming this is normal. It's not really Noticeable

This is by design. All units have it.
My Amoled devices aren't as readabled in direct sun light. IPS text is so crisp. But as it's been mentioned it's lcd, so there's always gonna be a brighter edge where the backlighting originates.
Hey guys so I just picked up my LG V10 2 days ago, I knew there were some issues with light bleed on the upper left corner of the 2nd screen but I crossed my fingers and hoped for the best.
The first night I had the 2nd screen off, however last night I decided to give it a try since it seemed like an elegant idea to have on this phone.
In the darkness of my bedroom the light bleed from the upper left was utterly atrocious, it actually fans out and extends into the other screen to about where the notification bar is (this is with the main screen off). The light bleed is also quite bright at night, it is very visible from across the room and really destroys the user experience.
I'll update with photos this evening as I want to know if other users have a significant problem or it's something that happens on every few phones and I can exchange for a unit that hopefully has less bleeding.
I'd love your feedback on how the 2nd screen bleeding WITH MAIN SCREEN OFF is for you especially in a dark room.
Yeah mineb does exactly that..doesnt really bother me too much
If you're in a very dark or completely dark room, you're going to notice light bleed. It's unavoidable with LCD technology. Mine also bleeds a bit into the regular display. Look at the screen directly (not at an angle) and it should look a little better. Angles produce worse backlight bleed - you're going to notice when you're laying in bed and look over at the phone and see the backlight bleed being a lot worse.
The big concern is if the backlight is actually bleeding in normal day-to-day conditions. On my first phone, I noticed in the STORE that the upper left corner of the notification bar was brighter than the rest of the screen. It had backlight bleed bad up there to the point if it being visible in daylight on colored portions of the screen. Exchanged it for another phone on the spot and it looks completely fine now. In most conditions the second screen appears to be floating because your eyes are adjusted to the brighter ambient light and can't see the poorer contrast ratio of an LCD compared to an AMOLED. At night though, you will definitely see that the second screen would have been executed better if LG would implement OLED in their flagship phones.
I see a little bleed on the left edge of the second screen, when the main screen is off, but it doesn't bother me. I kind of like that the notification icon is brighter than the rest of the second screen because it helps me notice that I have a notification, especially since the phone has no notification LED (shame). The second screen is not important to me, plus I don't see the bleed when the main screen is on which is when I'm actually spending significant time on the phone.
There reason you see bleed is because the second screen has a dedicated white LED on the left edge that's separate from the main panel backlight and positioned to "inject" light from the side without being properly integrated with the panel's backlight diffuser. This is why you'll see this, to varying degrees, on every unit. When you're in a well-lit room with the main screen on, the second screen looks perfect, because that secondary LED is off when the main screen is on. Also, the second screen auto-dims based on the amount of ambient light, so you might see the bleed on the "high" mode when you first turn off the main screen, but not when it dims down to the "low" mode after a while. Maybe they'll introduce a new hardware revision that repositions the second screen edge LED or does something else to limit its bleed. We'll know in 1-2 months when the next batch of V10s hits the stores.
I replaced my V10 twice because it had yellow bleed at the BOTTOM of the screen by the navigation buttons and that annoyed me as hell, since it affects the colors of everything I do, especially watching movies. All three had second screen bleed. What was particularly interesting is that each had a different color temperature screen. My first one was reddish, the second one was blueish (like the G4), and my current one is greenish, it actually looks exactly like the Nexus 6P screen (I put them side by side to compare).
I'll agree with Nitemare3219's and siraltus' observations and comments. When the main screen is on nothing is really noticeable. When the main screen is off I have the second screen off. It's so dim I don't see the point to having it on. The second screen is a bit of a gimmick. If I had additional issues I might think of exchanging it (still have 10 days), but I don't notice any other screen issues, and my fingerprint reader works...with a case. Every LCD screen I've had has had some sort of bleed. The problem starts if it is noticeable during normal use/viewing.
Mine slightly lights up the whole right corner 1/5th down the screen, only visible in a dark room. I dont get bleed from the right like ive seen in pictures and youtube.
It's only noticeable when it's pitch black and my main screen is off, so it doesn't bother me at all. It's not noticeable any other time.
First the second screen has already become a staple of my use habits, it's no gimack. Yes bleed is there when main screen is off, no I don't like it, but don't feel it's as big an issue as some make it out to be. That's just me though, I can see it bothering some.

Same, the light bleed is noticeable in the dark, but not bothersome. It is not nearly brought enough to light up my room at all, and is very slight in the upper left corner of the second screen. For the usefulness of the second screen with my usage, it's an ok trade off for me.
If your not happy with it and your within the 20 days id return it. I did return my initial one and my second one is better with less bleed.
my bleeding is always noticeable but especially on dark rooms,
