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.

Hi Guys - great phone which I've had a week or so now. Upgraded from the first Galaxy S.
Now I must admit to having very good eyesight (sometimes wish I couldn't see finer details!) and..
On white / grey images (download the various screen test apps to have a look for yourself)
The screen, when on a low brightness, is "muddy" and demonstrates a few vertical darker lines on the screen with mine showing quite a prominent one in the bottom right heading up about half way up the screen.
This is mostly visible when the brightness is at a minimum (regardless of auto or the powersaving options)
When the brightness is turned up it is barely visible, if at all... looks fantastic..
But.. at this point I preferred the screen on the Galaxy S which, when dimmed was more vibrant and didn't have this "problem"
Hands up who can see what I see? Any darker lines visible on your white / grey backgrounds? a side effect of this new subpixel arrangement? totally normal? some pixels not as bright in a row hence darker lines?
What do you guys think?
Cheers, B

Could you take a pic or something?
ASAP yes (no camera ironically so will have to ask a colleague!)
hold menu and press power button for screenshot off the device.
Yeah, mine set to minimum brightness and has some line artifacts like when LCD supplied with low voltage. (low brightness setting)
Easily noticeable when displaying grey colors.
I'm also using Screen Filter app, setting brightness even lower, some black points around 0.3cm is exposed at night.
Not sure those points are affected by anti-scratch film though.
Hola
I can confirm that I see the same "line banding" effect when using the device with low brightness. Like others have mentioned I also use the free Screen Filter app to get even lower brightness levels especially when reading stuff in bed in the near dark.
I would think this is a side issue with having the Super AMOLED Plus type screen but I guess only a Samsung tech can confirm.

65" long exposure exposing some black spots.(digitally enhanced)
Lowest brightness + Highest brightness.
Wondering those spots are caused by screen protector or defective screen or limitation of current AMOLED's.
You can see there is some current leak.(It should be bezel-like black if it is ideally off)

Not sure I understand you cpu98!
Is there a consensus we all have this "problem" - i'm on the verge of taking it back for a refund and "monitoring things"
Anyone understand the tech / spoken to Samsung?

Not sure what those black spots are... is your camera messed up? There's spots on the right even off the phone...
Also yes, pure black for SAMOLED still produces SOME light, but it's almost indistinguishable to the human eye.
Take a picture of a dark grey image on low brightness and it should show the bands the best...

That spot off the phone is on the wall not defective cam. As you can see photos are taken at different angle. And it is visible in naked eye.
Yeah I like its screen very much. That black issues are no problem in real use.
I'm very satisfied.
Hello to all
As the title says it's another screen defect that this phone have
I have noticed a darker area, which make almost a perfect rectangular shape upper to left of the screen and it is visible only in some circumstances
- screen brightness need to be lower that maximum (the lower it is the higher this defect is visible)
- mostly visible on grey image (for example the market startup) see other images in the links

http://imageshack.us/photo/my-images/864/img0633u.jpg/
not visible at all on black screen of course but when the screen is off and with a bright light (sunlight of a power lamp) in some right angles I can see some darker dots (looks to be some kind of liquid inside the screen) at the size of 5mm and also this rectangular shape (good eyes need here ) no picture for this because it is not visible with any camera
I wonder how came to this and is any possibilities to fix this such as those screen burners, could these help? or only a screen replacement?
PS: phone have no waranty
Thanks
Screen burns are permanent on AMOLED as far as I know. You'll either have to live with that or do a costly screen replacement.
Ah well, guess I have to live with it, not a major problem but it's looks a bit ugly sometimes.
Just read a bit more about amoled screen burn and it seems that the blue leds are the most that probably get weaker in time and causing this screen burn, and yes this is an explanation why on a blue screen this is almost not visible no mather of the screen brightness
Maybe burn all the screen with a white image, but I believe the result can be worst that this
Thanks
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
I'm new to android and just bought my s3 so forgive me if it's a stupid question
Whenever I watch a movie, there are two or three black spots. I feel like they are dead pixels. It doesn't show up on a white background nor on my ics inspired background but now I notice it a lot during a movie especially if it's a dark colored movie(darkness and all). Are these dead pixels? Is there a display app which I can use to display pure different colors and find out?
Thanks in advance

Spots? If what you are describing look like smears on the screen then no, I think this is an unfortunate defect with oled devices when black is viewed in really dark environments. My phone (not an s3 but uses amoled) exhibits the same problem and my PS Vita shows it very prominently.
A dead pixels is just a pixel (pretty much a dot on the screen) that is stuck in 1 color no matter what's being displayed onscreen.
There's a test screen, just dial *#0*#
However the black spots on dark background when your screen is on minimum brightness (e.g. in darkened rooms) are well-known issues plaguing AMOLED.
There are several threads around here describing them and their possible cause, and at least one developer has announced working on a screen tweak solving this and other typical AMOLED issues.
Yeah it's only noticeable on dark backgrounds with low brightness. I downloaded display tester and ran the dead pixel test and the smears were only noticeable if I looked super hard during a black background, not in blue or red or yellow nor gray. So no dead pixels right ?
Also thank you so much !

If you didn't notice any stuck dots, then your phone is good. As for the smears, pretty much everyone has them. I guess you have to be extremely lucky not to have them (that, or you just haven't noticed them yet so it doesn't bother you). The software solution pointed out above sounds interesting though. Will be watching that
About Dead/Stuck pixel on OLED Device Display
I have a S3 GT-9300 that I use daily, the other day I dropped it on a hard surface and a single shiny green stuck pixel appeared on the bottom left corner of the display, it was a bit of an eye sore really, But I'll share my simple FIX if its a related problem like mine was
I thought if the drop caused it, then a related solution may fix it, so I simple activated display and went to the home page.
then I turned the display facing my palm and held the device carefully at the top end and slapped it several times hard into the palm of my hand where the pixel problem area was. then stuck pixel went away...
I hope this works for you too :good:
Hello, I own a i9100 and I have some burn-ins at the top of the screen that replicate some buttons of a browser or something, and some burn-ins at the bottom as well. I have read that leaving overnight an app that's constantly switching colours, with full brightness, could help a bit on that. I also read that leaving a blank screen (white image) on the same conditions (overnight, full brightness) would help as well. My question is, how true these both things are? I don't want to end with a bigger problem than the one I currently have. The burn-ins are most viewable at Blue, Red, and Black screen colors.(like if I put a background with one of those colors on it)
Never had any of these on my S2,but from my experience with the galaxy s plus,these tricks won't work.None will to be honest.It's permanent.This shows how immature amoled technology is.Learn to live with it or replace the screen if that bothers you much.
what a sign you got there...
Lucky you. Mine is not THAT noticeable if you're using it normally, but as soon as you open something with a plain color on it, the burn in shows itself on all its glory. So right now you can't tell if leaving the white image all the night or the thing switching colors will damage my screen more?
mwehehe
Well,back then when I tried every method you described above on my i9001,I didn't noticed any improvement nor any further damage.Even after running those for 10h+.So I assume it's safe.Can't say the same for the S2 though,have no problems with it.
