So being that im a tv whore (own a krp kuro) i was playing some pioneer demo material on my gs2. The demo has a ton of awesome dark scenes that really show off how black these amoled displays can get.
There was one part where there was just a black screen for about 10 seconds. Since i was in a dark room my eyes adjusted and noticed all these Blotches all over the black screen. Is this normal? I see it on a 100% black background that i created as well. Any one else have this issue? It kinda dumb i know since i only see this in a dark room with a black screen but its bugging me now. I would be devastated if my kuro looked like that in a dark scene so my phone isnt any different.
Im on a bravia engine Rom with screen mode on movie.

Normal, and might have come up in searches for "screen." People have complained here, asking people to go in closets and perform rituals to see if spots and lines appear. I will have your TV now. Thank you.
Righto. So I just took a picture of all black, then let my eyes adjust to the screen in the dar.... AND HOLY MOTHER OF MAY I? YES YOU CAN, WHAT THE HELL IS WRONG WITH MY SCREEN?!
Are all screens like this? Is there something that causes this? Because I honestly don't remember ever seeing these blotches on my screen, and i even looked once before.
Now it's so bad it looks like my phone has some venireal disease or skin-touchscreen cancer.

Seems like people are getting into a very humorous mood with the holidays, and it's spilling over to even serious threads.
What you describe is a defect of the screen. When the phone first came out, and for the first few weeks, there were a number of people who reported problems with the screen. The way to test the screen that was suggested at that time is exactly what you did with the black screen in a darkened room. I tried that test, and my phone has a completely black screen, with no light patches.
For some reason, there havn't been many reports at all since the first few weeks. You are only the second person I've seen to mention it, I think, since then.
The people that had the bad screens just exchanged their phones until they got a good one. Of course, at that time everyone was still within the 30 day period.
I was bein serious creep. I might have been comical in reply, but i genuinely want to know why my screen looks like crap now.

Thanks for the replies. I see if i can find one with out blotches at best buy

Actually, I'm quite certain this isn't a defect. In fact, it's just something that samsung says comes along with the Amoled technology, if you do a thorough search in google, you'll find multiple articles stating this. Do I think that since samsung screwed up on all these screens they are just saying that? Absolutely. But I also think that anyone who says they don't have it at all just maybe doesn't have it as bad. When I had the T989, it was so visible it annoyed the **** outta me, and it wasn't just splotches, but it was lines and stuff too. Now, I'm on my 2nd i777, and the first one had the splotches, not too bad though, and the current one I have is even less, but it is there, although you really have to stare and allow your eyes to adjust to see it. I think the next generation of amoled displays should have this little kink worked out, but if you look on the Razr forums, the t989 forum, and the skyrocket forum, they all have it as well. Its an all around AMOLED issue, and i dont think any displays with a Super AMOLED+ display are without it.
I'm the one who said my phone has a completely dark screen with no light patches. Well, that was a couple of months ago that I tested it, and I decided to do another test today. My house has a room with no window, so it is easy to get a completely darkened room.
When you put a black image on the screen in a dark room, the screen is not completely black. If you set the screen timeout to 30 minutes, and let your eyes completely adjust to the dark, the screen actually looks rather light, a sort of greyish. But the shade of grey and amount of light intensity theoretically should be uniform across the screen.
My screen is actually pretty uniform, but there is a slight gradation to darker arount the edges, a little more pronounced toward the top and bottom than on the sides. There is one very tiny area at the very top of the screen right on the edge directly below the AT&T logo, that is significantly darker than the rest of the screen. The difference in light intensity is not very much, but it is noticable.
The gradation of light intensity on this screen is so slight that it would be impossible to detect any difference in light intensity in normal screen use. People who have reported this problem are the ones whose screen is so variable, that they can see the difference during normal screen use. And if you would test one of those screens in a dark room, I'm told you would see a very marked difference in the light intensity.
So I say that if a screen is such that you can tell the difference when using the screen under normal conditions, then it is defective. But what Samsung or AT&T will say and do about it, I don't know. I havn't seen any reports from anyone that has tried to exchange their phone for that reason.
I tested screen out last night too and saw a few darker splotches around the bottom and side. Then my ocd kicked in. I was considering exchanging the phone today, but after reading this thread decided against it. Thank you all for the info

I'm not really concerned if my screen suffers from this but I have a question:
If it matters, at what brightness is your screen set to when you do this?
Sent from my SGH-I777 using XDA App
I had mine set to maximum brightness.
My screen also has the blotchiness but honestly i cant think of one time where this was a problem. you just dont notice it ever in day to day use and if you have to get in a dark room with an all black screen to notice it then i dont care.
I didn't want to start a new thread so I'll bump this one...

So I've noticed lines and stuff when I go into the market/google play (the grey shows multiple verticle and horizontal lines, but I have to look a little hard. Not too big a deal.) However, I tried using auto brightness which defaults much lower than I had it set to manually and the screen shows tons of lines everywhere. For instance, I use ryude's unoriginal rom, and with the stock messenger (bright white) I get a ton of lines. I was wondering how many people use auto brightness and if anybody else has this issue. I'm out of the 30 day replacement warranty, but I have an upgrade coming up soon so I'm not super worried about it. But still...

This. I am on my fourth phone and all of the screens have been jacked up with splotches. Some worse than others.I'm going with a super amoled+ thing and less of a defect. Don't get me wrong, it drives my ocd nuts knowing that its there, I just try to avoid situations where you can see the splotches.... especially if I'm trying to show the phone off lol

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
Sent from my GT-I9100 using XDA App
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?
Hey guys I'm getting this phone on Wednesday.
Just before I get it and use it can anymore comment on any issue with burn in? Subpixel life etc.
I'm going to use this phone quite often. It'll be on at least 9 hours a day on charge and off.
What kind of life can I expect from the screen? Not bothered about battery life.
If its bad I'll return it and get htc one x or something with LCD or else.
Thanks in advance!

If you are worried out burning then make sure you switch back and forth between portrait and landscape so the status bar won't always be in the same spot.

Funny enough how (most) people never really cared about screen burn-in on plasma televisions, LED televisions and good old CRT's but go frenzy about AMOLED screen burnin.
I've had my S1 for 2 years with probably more like 12 hours per day screen-on and it really is fine. On uniform backgrouns (e.g. all red, green, blue..) you can see the lines (most prominently the status bar).
On several launchers (e.g. GO) you can hide the status bar if that's of concern to you, there are additionally several apps trying to make it far less visible by uniformly burning colors in your screen.
Of course there are always "bad" screens which burn in easily just as there are bad LCD's with stuck/dead pixels.

I think people do go crazy about screen burn ins. You're just not taking a good pool from different kinds of people, tech geeks vs average consumers, where there are more average consumers who do not care.

Ok so it doesn't burn that much? I've had burn in on plasma before it was really annoying. I'm planning on using this phone for 2 years+ for games and camera mostly. is there an auto wallpaper changer/cycler?
So i've heard that the S-AMOLED and S-AMOLED Plus technology has "Perfect" Blacks! Like the Blacks don't even "Light-up".
Is it true? Or is it just a marketing thing? :/
Try this and tell me what do u have?
Turn off all the lights in the night and then view some BLACK picture. U'll see that the Blacks are kinda "Greyish" :/
And there are some pixels that are perfectly black.. but they're just Random... :/
known "issue" on lowest screen brightness
Ohk.. So its not "Completely Black".
theres also another problem with it aswell... When I view some pitch black picture in a completely dark room. I see some small rectangular shapes that are "Pitch Black" in that Greyish background. I cant snap a picture of that unfortunately but u kinda get the idea. Can someone try this with there own S3 and report me? :/
It'll be quite helpful
Is well known issue.

Mine does the same thing: darker black splotches when viewing a black picture on the dimmest screen setting in a dark room.
Fortunately I don't often find myself looking at all-black images in the dark. It's hardly a major issue.
this issue is quite common, even on iPads, Motorola etc...apparently it is the adhesive within the layers of the AMOLED that causes an "ink" mark when screen displays black images within a dark environment...nothing is actually wrong with your scren, mine has 2 very small dots...while my other friend has had his replaced because the issue was far more prominant...so there is a possibility of claiming warranty? but this will depend on the country/retailer/etc...but always worth giving it a shot if you cant stand this issue...but yes, earlier batches, the issue was far more obvious...but later ones are better but information from other XDA threads suggest that you WONT find a unit without any marks...period.
