I have used a Galaxy S from an year until recently last week, i exchanged it to get a new Galaxy S II. I like the phone very much and i still think its the best phone ever made. But i notice that even my screen has the yellow discoloration problem as others. I don't bother much about it but what made me curious was that a friend of mine purchased a new Galaxy S a few days back when i brought my S II. I put both the displays side by side and noticed this
1) The display of the Galaxy S was much brighter than my S II at 0 and 100 levels of brightness. I felt that my S II screen was more dull and yellowish while that of S was brighter and greyish
2) In direct sunlight, the visibility of the Galaxy S screen was more than my S II at both 0 and 100 levels of brightness.
I was surprised by these findings and I want to know whether
a) Super AMOLED+ brightness is supposed to be better than Super AMOLED ?
b) Or does my SII have a faulty screen and can i get it replaced ( purchased mine a week back) ?
To be honest, i always used my old Galaxy S at 0% brightness and even at times i felt it was too much brightness in a dark room, so used the Screenfilter app. But thats not the case with my S II, i have to use it at around 20% in the same dark room. So, i want to know whether my particular screen is defective or is it the same for everyone else ?
Settings display background effect: choose dynamic
And you can turn off the adjust screen for power option in display settings

u sure u disabled power saving mode for the display? That usually causes a duller/greyish screen...

All I can say, we all have the same GS II, same screen, same Yellowish tint, Bluish white in Auto/Low Brightness, some admit it, some not. If you wanna exchange it, exchange it, but I bet you will a same screen like before. And the comparison about Super AMOLED and Super AMOLED +, I too think that S-AMOLED is better than Plus in case of Low/Auto Brightness. I previously had a Wave S8500, and I never turned the Brightness to even 1 in one year as on lowest settings the screen was gorgeous. But I can't say that for GS II. I disabled the Auto brightness already, I just can't take that Bluish White effect. I am on 20%, the screen is cool now, still I am not that impressed with it as I thought I'd be. I don't think it's a feature of S-AMOLED Plus screens but a manufacturing fault, now Samsung admits it or not it's a different story. But I still hope that a Firmware update could turn things in the right way, just a hope. I purchased this device for only having another OLED screen, cause I've saw ARC and Play, and they just couldn't stand against my Wave, but if I knew that GS II would have this type of screen I'd not ignored those phones. Let one more OLED+ device from Samsung get released and if that one has this problem too, I am out from Samsung forever, yea I know they simply don't care for one customer, but I do care for me.
Regards.
I have disabled the Power saving mode, and also tried the three different modes- standard, dynamic, and movie. But i didn't find much difference. SAMOLED+ is supposed to be brighter than SAMOLED, right ? Other than this the phone is marvelous !!!

I used a Galaxy S and it was an excellent phone with Lagfix and Darkys ROM. Briefly, in between I used an Xperia Play for a few days and it was so laggy, many apps used to force close, etc. So i decided to go for a dual core and I think there is no match for S II in this regard. I am very satisified with this but just wanted to know about this SAMOLED+ screen and it was supposed to be better than SAMOLED. To be honest, i always used my old Galaxy S at 0% brightness and even at times i felt it was too much brightness in a dark room and hence used the Screenfilter app. But thats not the case with my S II, i have to use it at around 20% in the same dark room.

Whoa there! Extreme much? You'll never get another Samsung because the screen isn't bright enough at 0% brightness? Lol. Are you serious? Oh well, to each his own.

The plus got nothing to do with brightness but with subpixels. Its red blue and green in every subpixel where amoled got red green and blue green. Makes the image sharper to read.

Yes, that's correct. It's not an improvement for me coming from S-AMOLED and I don't like it. When I've seen better I won't bear a lesser.
You are correct in that part.

Does anyone know, how much power is saved by using the display powersave mode? I just tried turning it off and the screen looks much brighter and crisper. Is activating power save mode worth it?
My SGS1 not as bright as this one and not ad good in sunlight.
Yellow tint if i have it i dont care i dont see it.

SGS is slightly brighter than SGS II. It's in almost every review that measures screen brightness. AMOLED Plus was updated for sharpness, not brightness.

I am not bothered about the yellow tint either. What bothers me is the brightness level of SGSII when compared to a SGSI. Having used a SGSI for an year, the new SGS II has to be atleast equal to it. But lesser than the previous one is unacceptable. Thats my point

Yeah it seems a strange comment.... one thing that always annoyed me about the original Galaxy S was the screen was TOO bright on the lowest setting - it was a nightmare if you were using it in bed with the lights off.
I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?
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?
This is my first SGS II and it seems the colors are quite dark especially the photos on my screen
Sent from my SAMSUNG-SGH-I777
Ok that's weird the FB photo seems better in the screenshot posted here then it actually is.
Brightness?
yea but the only way it looks halfway decent is if I have the brightness up 100%, which I understand if you want your battery to last you at least halfway through the day the brightness should be lowered. I currently have it set at the halfway point. I was just curious if this is how all SGS: II are with the onscreen images? I was going to stop at the nearest AT&T to compare the 2, but just wanted an opinion here first.
For what it's worth, my 2-year old Captivate's screen still looks brighter and more vivid than my brand new SGS2 screen. I just live with it. As long as I'm not side-by-side comparing it doesn't bother me and my eyes adjust to the darker screen.
I'm on stock KK6 and use auto brightness.
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.

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 )
Sent from my GT-I9300 using xda premium
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
Excuse me if I am being naive but where is real life use would this ever be a negative impact?
