I bought my SGS 2 (used by another person for about a year) a few weeks ago and I have noticed artifacts on the screen, the individual pixels are not lit evenly, creating patterns on solid color surfaces. It is visible mainly on grey background (blue works quite well too). Just try to move a medium grey patterned background around and you will probably notice it. I guess this is the SAMOLED+ deterioration... Also, try displaying a black picture in Gallery in a dark room. The pixels on the screen are lit slightly, but some are darker and they form "blotches".
If I had known about this issue, I would have bought a new SGS 2 and not a preowned one.
Have you experienced these issues too? Could you check this on your phone and report? Things to report:
How old is the phone?
What has been your usage pattern?
How bad are these screen issues?
Are you experiencing different problems with the screen?
Maybe we can find some trends and estimate the service life of SAMOLED +

You have proved that I am not insane xD I too have been seeing these lit up bloatches on the screen whilst on a black wallpaper.....
I've had my S2 for over 6 months. I've been using it everyday since then and maybe 6 hours screen time in total(daily). The screen issues are not bad at all..Tbh its only there if you really try to find it. And no I have no been experiencing any other issues.
Have a good day and good luck with your S2

I'v noticed a burn in signs somewhere in the middle of the screen (later I'll take a photo), its looks like a little shadow, darker...
Seen it only when I used RGB screens...
There is something to do (without replacing the screen)?
I'v heard about 2 options, donno how much its safe or will effect:
1. Using Jscreenfix - most for stuck pixels (its not the situation) but maybe it will do something after running few hours
2. Use blank white screen for few hours while the phone is on.
some says with full brightness, some says with low brightness, some says it will burn in the screen and will cause more damage....
Do you have any experiance with these 'methods' or any other tips to get it fix or halfix?
Thanks!
Are you using a non-oem battery? I order one from eBay (yes, I know ugh) and it was a snug fit and caused dark spots on the screen from the pressure.
Mine has a dark spot too, right in the middle of the screen. Looks almost like a shadow. I noticed it the first day I purchased the phone, within 2 minutes of first turning it on so its not burn-in. Its more noticeable for me on white screens like the google search page. I seem to recall one of the many cell phone models I've owned also having this problem. Maybe EVO?
Personally it doesn't bother me but I could see how it would drive others nuts.
I can personally vouch for the jscreenfix when you have issues with stuck pixels, however i dont think it will do anything for a burn in or dead pixel. I had a cluster of 4 or 5 pixels on an old blackberry of mine get stuck and played that jscreenfix for hour or two and it brought them back. But like I said I don't see that helping with a burn in though, if that is your issue.
Here's a picture of this burn-in, bad quality but can't miss the 'shadow' ...
@jrebo - I'm using the original motorola's battery.
Any chance it will 'fix itself' or there is nothing to do?
What about the option of using a white blank screen on with low/high brightness ? will it make it worst or its possible help?
Thanks!
I have a white spot in the middle of my screen and I've been using the oem battery.

Why these dark spots / clouds appears anyway?
Seems like its happening at lots of smartphones...
I have a Nexus One which have a top notification/status bar burn in - maybe because it was on the stock rom with the white bg and set to be shown all the time.
But here its looks different, as you mention - cloud / smoke / dark spots...
Still not sure if keeping the phone on with full white BG will do the job or will **** it up more.... also not sure what brightness should use with this white bg...high or low...
@jrebo - about the replacement battery you bought, after how much time using this non-oem battery you've notice these dark spots ?
I'm considering to buy another battery from ebay (there is no other place here to buy oem batteries for photon) seems like there are some 'OEM' batteris (HF5X) out there with tag price of ~10$, not sure if its real or knockoff and what problem could it cause...
screen burn in can not occure on lcd and plasma displays since there is no phosphorous layer that the colors are being shot through... however there is something similar but its not permanent... pixels of other colors are not releasing there charge so they end up not going back to their neutral state. To cure this issue you get any one of the apps out there that run your screen through random colors every so often or leave the phone off and with no battery for a few days that will get rid of the immage permanence that you see. if that area on your screen is showing a cloud that does not match your current wallpaper than there is some other issue going on. and to cure that i have no clue lol
There are a few threads out there that have touched on this issue but none as far as I can see that deal with it directly.
The problem comes when you display a pure black screen in low light conditions. It shows that the AMOLED screen is actually grey / blotchy / cloudy instead of being pure black. Initially I thought mine had fingerprints or smudge marks on it, until I realised they were behind the screen. I guess I might have got a phone with a screen that was replaced, but the amount of people who have also reported a similar issue leads me to believe that it might be a manufacturing default? The blotches / clouds on the screen dont change, but exhibit a random formation as one would expect from a defect. It is also possible to see a very faint outline of light running along 3 edges of the screen.
Naturally this is a situation that doesnt reveal itself very often. But I as I use my phone a lot at night, especially reading ebooks or watching films, you start to notice it more and more where you have large expanses of empty black screen.
What I would like to know is how many people have got screens that exhibit this behaviour and how many of you have sent them in for service or had them replaced?
Is it a common issue and something that is to be expected from this type of screen?
You can test if yours has this problem using 'Screen Test' (its free) from the market place. It cycles through solid colours and patterns every time you touch the screen.
Just do it in bed with all the lights out P), give your eyes a few seconds to adjust and see what your screen looks like displaying pure black.
I'm very interested in everyone's experiences and any input or information you have.
Thanks everyone in advance!
ps: I came from a ZTE blade (OLED) which has a uniformly dark grey background when displaying pure black. I kinda expect this as it is a budget phone (albeit with a better than budget screen), but I didnt expect the SGS2 to be quite as bad.
Use "screen adjuster" from the market and set contrast to -60
i have never seen this black low light screen defect. but i am asking you people if any of you have noticed that ugly blurry shadows which are perfectly visible with low light, on white backgrounds especially. they look like marks above the actual display and make high quality images look like low resolution.. it is annoying as hell..
I have this. Noticed it one night when my phone was switched off and charging.

I also have this, noticed the first evening i used the phone...you can notice this during the screen wake delay, or when in a call if you cover then uncover the proximity sensor...don't know if it's a defect but sure it bugs me, i know many won't notice it and will say they don't have this...i will add that if u look carefully to the screen dimmed at lowest brightness in a low light (buy not dark) environment, like early morning, you'll see some "interferences" behind the image, also the darker/yellower left half screen is still visible in these conditions
These things shouldn't be there in a 500€ phone

Thanks for the feedback already.
@elmerendeiro: I have also noticed some 'interference' lines on my phone from time to time. I did a bit of research and it seems when your phone's brightness is set around 25 - 30% it picks up interference from either the wifi or 3g radio. Notch the brightness either above or below this level and you wont see it anymore.
I agree with you when you say we shouldn't be having these problems on such an expensive phone.
It bugs me too - if it wasnt for this i'd have to say it would be an amazing phone
Might give the Samsung service center a call and see if its something they're aware of and if they are replacing screens with this problem?
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:
I just bought a s3 and noticed that in the dark if I use an app with black background or a wallpaper there come Some strange dots on the screen, is that normal and could someone please check about they also have it on their s3

Yeah its something to do with amoled displays. My galaxy nexus has the same type of splotches. From the research I've done they are pretty common. I've seen some pretty bad ones. Mine isn't that bad I have 3 towards the lower middle part of the screen. It looks like this
-_- lol. I've seen others much worse. You can also notice them slightly when the screen dims if you know where to look. It is really annoying but from what I can tell its pretty common on amoled screens. You can Google amoled black spots to see just how widespread it is.
Sent from my Nexus 7 using Tapatalk 2
Ok thanks I just got so nervous, I was thinking it was something more worse. But Should I go to the phone shop and remind them about the spots so they could fix it or will they just say that's a common problem we can't do anything about it
It's nothing that can be repared since it's a manufacturing inconsistency but not a defect per se.
Usually they are only visible in total darkness with lowest brightness settings on black backgrounds which is not that much of an annoyance
since you usually don't stare for hours on black screens. (Well at least I don't)
It's sometimes annoying, yes, but that's the downside of having low-power high-resolution displays without Ghosting problems.
Hello,
I have my Mate 10 Pro since one week and two days ago I used it at night and spotted that a little portion of the screen (at the right border of the screen) is much darker on gray color than the rest of the screen.
You can see it in the attached photos of my screen. It most visible in the Google Clock app where all the background is dark gray... It's not as visible as this when I use it in a more enlightened environment.
I think that the screen of my phone have an issue.
As it's a OLED display with no led back light there shouldn't be this kind of issues (it's like a clouding on the LED screens).

Will do ! I was just curious if I am the only one with this kind of issue. It's really strange.

I'm thinking about exchanging mine too. I also see uneven Grey's and whites
I think it is just that the app is showing not a flat background, but a background with gradient. It is more beautiful when app backgrounds are with gradient, than just flat. So with lowest lightning the contrast of different levels of intensity on the background are more easy to see.
It's not a software gradient, it's a screen flaw. It's called Mura effect. Affects mot OLED screens. Google Mura effect oled for more info. I was so sad when I first noticed it on my Galaxy Tab S 8.4 (changed it twice with no luck), and then on my Galaxy S5.
Now I'm going for IPS screens which imo still suffer from less flaws than OLED.

Anybody experience data problem when switching back from wifi mode?
Hello
I have the exact same issue and it's really bugging me...
I went and showed it to the Service Center and they accepted to exchange it for a new one. I'm waiting for the replacement in a couple of days...
I'm glad I wasn't the only one experiencing it!
Send it back and get a new one from Amazon. I saw this problem with the camera in white or clears walls. It seems "banding".
I acquired a second hand Mate 10 Pro 3 weeks ago (first owner bought it on the 24th of November), it already had burn-in zones: navigation dock button, Google Search, bottom system buttons bar and many other ones from various apps' icons... These zones are mostly noticeable on clear or white screen/pages (eg: about:blank URL in Chrome browser). At reception, I immediately selected a black theme and activated Battery's dark mode. Now I can see my own apps setup marking the screen... After only 3 weeks...
Am I the only one ?
I'm contacting Huawei customer service.
