It is a common belief that SAMOLED has no backlight, which is true. However, the screen IS powered and hence there is SOME energy that generates a teeny tiny amount of light.
This can be checked by using the *#0*# and doing the Vibration test where the screen goes totally black.
I'm talking about a VERY VERY faint and very uniform glow from the screen.
Try waving it in front of your face if you don't see it.
Report back.
Hi,
Yes. Even I have noticed this when I am using the cell in night and in a completely dark room. I am not sure about the SGS 1'S screen, but in the S2 I have seen a very faint glow which is present in the backs even when there are other elements colors present on the screen. It's my opinion that there is some amount of backlight that is being used for the black.

Both the i9000 and i9100 have a faint glow when nothing is being shown on the screen
I havent seen any glow just how "teeny tiny" are we talking about here?? If you keep reasonable distance from the screen then it is perfectly black. Watching a video with black bars in a completely dark room the blacks are literally indistinguishable from the bezel.
so far i had 3 galaxy sII devices the last one was the white color
all of them had the same thing ur talking about in complete darkness
Yes both the i9000 and the i9100 I own have this, you can also spot it while just turning on the phone before the boot screen, but I only notice while in a dark room or at night.
The faint glow is there because the pixels do not totally power down when displaying black. The screen is designed this way to give better response rate. No one wants a screen that ghosts isn't it

You only see it on a fully black screen. As soon as there is anything on the screen your eyes compensate for the light and you lose sight of the black. Try it as the OP suggested and you'll see it.

Okay so we are talking fully black screen.
So while watching videos, playing games or having a black wallpaper(with obvious widgets or icons on top) the eyes would perceive it as pure black as I have experienced.
So for all practical purposes the contrast is infinite. OP you shouldnt worry about some glow on a fully black screen. I can tell you for sure that even in totally dark room lets say you are in the ICS app drawer you will not be able to see any glow between the icons, it would seem like the icons are flying in the air. The magic of SAMOLED.
Yes, there is a faint glow. But its only noticeable when you're in a completely dark room and your screen is showing only black.
However that does not in any way mean that SAMOLED+ doesn't have perfect blacks.
The glow is there only because the pixels aren't actually powered off (at least that's what I think)
The contrast ratio is still infinity.
The OP made this thread to prove a point, just checked and YES there is a faint glow in complete darkness.
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)
Hi, after two years with Defy I bought brand new Atrix 4G fw. 45.31.1.MB860.NonEFIGSRetail.en.EU, non rooted. The problem is that all dark colors like gray, dark-blue, dark-green, dark-red seems to be black. Rest of bright colors seems to be fine. For example gray menu with black letters is bright, clear and sharp but buttons like in Power Amp (dark buttons on dark background) has no borders and there is no difference between them and background. The same thing is with movies - daylight scenes looks nice but night scenes are so dark that it's hard to see anything. I installed Screen Adjuster too boost contrast and then all dark colors starts to be clearer and didn't split to black but rest of bright colors starts to be completely washed. Screen looks fine on bright background and it's alot better than washed up screen id Defy but on dark background there is no difference between dark colors, all looks black. Strange thing is that noone post this problem before so could it be factory damaged screen or maybe some software issue?? I really need help with it cause I payed for this phone the same as I sold my 1 year old Defy Plus and this Atrix is new so it would be nice to fix it, otherwise I need to return it quickly but I wont find that phone in the same occasional price.
So anyone can help??
Link to photos comparing to Defy Plus on the same frame.
Photos are not good quality but when You look on collar You should know what I mean.

I've the same issue, Chamelleon! have you found the way to fix it? now i'm running neutrino 2.9 CM7, so it doesn't seem to be a rom problem....
It must be kernel issue cause on AtrICS everything looks ok. Temporary solution is Screen Adjuster from Play Store and add some contrast. Colors looks more ****ty but You can see what is on the screen.

ty Chamelleon! i'll try
I am not referring to the pink hue issue, rather my screen looks as though whites are dirty? Like there are some spots a lighter hue than the area next to them. It makes pure white look as though it is dirty.
It is most noticeable at lower brightness settings, and it appears to be noticeable on any lighter color as well, such as the quick settings light blue.
I am curious if this is just normal amoled unevenness, or if it is something wrong. I've tried to get a picture but I can't get it to show with the poor cameras I have.
