I was in the o2 shop today playing about with the Galaxy S2 and I noticed that if I angled the screen slightly, everything would get a blue tint to it. This was most noticeable when there is a lot on white on the screen.
Is this a common problem with the new handset, as I remember reading a similar thing with the older super amoled panels?
I loved the phone, but was put off by the blue tint.
Thanks.
I've actually noticed this myself with a phone I bought from phones4u (avoid them at all costs). It's very odd I thought for SAMOLED since I thought they're not meant to have viewing angle issues like LCD and my old, original Galaxy S certainly doesn't have this issue. Also noticed slightly yellow whites. I got another SGSII from o2 (with bad GPS issues) that had a better screen but I must say - the evenness was a bit off and that was a big surprise given the SGSII is meant to have SAMOLED+ which is technically "better".
I'm beginning to think a bad first batch - i.e. rushed manufacturing.

Even though its supposed to have good viewing angles, its not supposed to be extreme like the iphone 4, there still will be a point with samoled that you will start to see a little distortion.. The blue tinge is on the first galaxy phones too, its something that is inherent with samoleds... You want to worry when you have the screen on full brightness and you see any yellow... But you will see the whites go a bit yellow when the brightness is low. samoleds have their own DNA and everyone is made differently. I do not think this batch was rushed at all, i actually think this is a better first batch than the first Nexus S batch, there was returns flying back from everywhere. I had 4 different NS myself..
I have also gone through 3 SGS2's but rightly so, two had a low hepatic feedback and press area on the back button and one had the piss yellow screen of death
But it worked out better for me because I returned the P4U one for 530 and bought an O2 one for 399. So faulty phones really do save you money;P

Very strange. I have ordered one from o2 online to be delivered in 30 days time as I have already got a contract with Orange that doesn't run out for 2 months and I wanted to take up the discounted line rental offer thats running at mo.
Hopefully most of the problems will be sorted by the time I get mine
P.S. I wouldn't use Phones4U either. Heard quite a few horror stories about them.
Anyone else noticed a blue or yellow tint ?
Thanks

The one I played with today had quite severe blue tint with minimal movement of the handset.
Have yet to see what the yellow tint is like.
I'm sure I read in a review that Samsung have put in an option to change the colour balance on the Galaxy S2 ?
I hadn't noticed this until you stated it in this thread, and to be honest I can only see it when there's a white background. Personally, I don't think there are issues that detract from the user experience, and that's all that matters!
The Samsung Galaxy S II is still by far the best phone in the market right now.

Yes they have,
There is 3 presets,
One is like a nexus s pre 2.3.3 colour, and one is a post nexus 2.3.3 and one is somewhere in the middle But what your seeing is something not linked to the colour balance, your seeing what is a screen defect. But a blue hue is quite normal and not so off putting as a piss yellow hue The blue hue was desirable on the galaxy S. The iPhone 4 will have better white replication than the samoleds due to that its a LCD screen, But the blacks will always be better on the samoled

Check my topic " different screens??? or what is this???" here in de Q&a. You see 2 different sgs2 next to eachother, one with blue tint, other not.
Mine has the blue ish thing too, but to me it seems more like a coating?
Last night I lifted my Phone from my desk on low battery and the screen went very strange and turned to a completely washed out green/blue colour. I hit the lock button and then unlocked again and it all went back to normal. Very strange.

I have noticed this on the Galaxy s2 I was looking at in the store yesterday.
If I tilted the screen only about 15-20 degrees whites would appear blue. It realy put me off.
That was the only model they had there though, so I could not check if it was a defect specific to that one piece.

Just a suggestion: it could be due to the gorilla glass. Could be a refractive property when viewed at an angle.

I have just purchased this handset on o2. Much better in the hand. I have a slight blue tint, but no other defects that I have noticed yet.
Am loving it so far.
I only have KE2 on my handset. Kies says its the latest version, but I have been reading about KE7?
Can someone point me to the correct thread please. Am very new to Android so haven't a clue really lol.
Thanks.

Any updates on this?
My replacement screen exhibits the same issue. Except mine becomes apparent while only tilting the phone 3 degrees or more off centre.
[edit] I can't post video links yet, but if you search "Galaxy s2 screen tint comparison" on YouTube, the first 20 seconds of the video highlights the issue.
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?

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.
Having played with my S III for a day now, I've been mighty impressed by the vibrancy and contrast of the screen, however, during the evening, when the lights were off, I couldn't help but notice something peculiar.
To be clear, I have no clear dead or stuck pixels and the issue occurs when the device is on, displaying a black screen (though I first noticed it in video playback that had black borders). I'm unable to capture a shot so I'll explain this as best I can.
When on a black screen, there is a faint glow, when looking closely, there are patches of very dark segments throughout the screen that are true black, as opposed to the general glow of the device.
Does anyone else experience this? Is it normal?
Many thanks
Do they look like black splotches that can only be seen when viewing a black screen.in the dark? That sounds like the same problem all vitas have, something that is unfortunately a side effect of oled screens. My current phone, a samsung wave, doesn't have this issue though I've read that some other phones like previous galaxy s models produce the same problems. Bummer if that's it since I hated it in the vita

Yup its on all amoled devices starting from sgs 2 but its less on some and more on others but still I don't think it hinders usage of the mobile
I have this too and find it quite annoying (even though you barely see it, only when displaying a black picture and in dark environment).
Would be interesting to know whether really all S3s have that.
Arg, curses! Yeah I didn't notice it on my SII which is why it was such a shock on the SIII. It's only noticeable in a pitch black room but sadly now I know it's there I fear I'm going to be picky
I hope it's not the same problem existed on all galaxy tab 7.7 models which you could see circles and spots on a dark background in a very dark room. My nexus s and sgs2 didn't have it but it was so annoying (for me) on tab 7.7 which I returned it and never got another one. Take a look at this thread: http://forum.xda-developers.com/showthread.php?t=1463622
I hope it's not on all models of sgs3,I'm planning to get the 64gb model...

Speculation and more speculation... for once I would enjoy if people posted some evidences when complaining about an issue with this phone..
had this uneven black and white patches in my sgs2. it didnt bothered me much frankly
I'm wondering if this is due d
To the difference between amoled plus and amoled(pentile)....pentile screens can look blotchy, more so than the amoled plus screen
From my nexus tappin the talk
<edit post successful>
What is so annoying about it ? I bet that no one is looking at a black screen for more than a few seconds in a completely dark environment.
Try this: light up a few pixels on the screen and tell me if you still see the patterns. I bet you don't! S2 has the same "problem" and the thing is that if you switch to landscape the patterns dissapear and re-align. I guess it's how the amoleds work.

If you check the pics in the thread I posted you can see many pics of the problem on tab 7.7. It needs a DSLR with good exposure abilities to make the problem viewable on a pic ( though it is noticeable with the eye in the aforementioned situation ). If the problem is as widespread as it was on tab 7.7 this thread will be explode with pictures and complaints. *fingers crossed* that's not gonna happen hopefully.

It's impossible to see in the light/day time.
You need a pitch black room, with screen test app turn to black screen,,,slowly the wriggly lines and patches will show up. It is annoying yes - 2 phones were exactly the same defects. Each phone had it's own wriggly lines etc.
Tried to take a picture but it's nearly impossible.
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 )

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?

no negative impact, but still raises a question "why so?"

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
So I currently own a Tab S4, Note 10+ and Note 8 and I've been impressed with the AMOLED screen. Today I got a Tab S6 and I'm severly disapointed by the screen quality. Compaired to the other AMOLED displays, this looks like an old LED panel, pretty bad quality no deep blacks, low contrast and the same image looks totally different over the two Tab screens. Additionally, when something comes up that blurs the background, the effect is more like a severly reduced pallet count rather than the normal blurring effect.
Is this normal for the Tab S6 or is this a bad unit?
I've also had trouble with the under screen finger print scanner not registering fingerprints, so I'm thinking faulty...
I haven't had any problem with the screen nor the fingerprint. Might be a bad unit.
No problems with mine...Everything looks great. Just a thought...When I first got mine up and running it looked a little dim as you describe. I went into the settings and put it on vivid and it lit up and was a totally different look. But if that don't help then probably a faulty screen.
Come from the tab s3 have an s10 plus as my daily phone looks just as good as the s10 plus in my opinion.
Nope it isn't
I did try that, but even with vivid on it still looked washed out

Yeah sounds like a bad screen....I would take it back.
The quality control is awful, I've had three which I've returned due to uneven black levels.
Samsung are obviously aware of the issues with the displays but they don't care because many users just don't complain about it, or don't know what to look for.
Apparently there are a lot of people having uniformity issues with their devices and there doesn't seem to be one free of defects. As always it's the OLED lottery! Exchange until you're satisfied.

We are all techies in this forum the average user would probably not even notice if the backlight was uneven especially if they have come from an old non OLED device I think that's probably part of the issue

Totally different look that gnus hooked people up on, and milliards of nobbs saying that amoled is way superior tehnnologi. Now it decided to turn around and present natural colour palette (with uneven wrinkled display to boot), i agree that it can be not so good to look at it after vivid

Im in the same position as you and I already bought 3 Tablets that had unsatisfying black levels. I feel bad for buying and returning them and I am asking myself if I should keep trying or just give up.
The OLED display on my note 8 looks so smooth and even. I wish I would find a similar tablet display.
Did you finally find a unit of the Tab S6 that has perfect blacks ?

Unsatisfying black levels? How is this possible? Black should be totally black LOL xD
Do you mean the grey color or something near black? Or you guys really talk about true black color? ( for example when booting up the device )
True blacks are fine, but it doesn't handle mixing very well - Compression and noise is easily noticeable at that point.
For example : The blacks in this video look terrible and Compression is easily noticeable when mixing the Vegas sign and the landscape of the city.
But in this video, they're perfect - The only noticeable problem in this video for me is when the camera is panning the planet and mixing black, purple and blue - at which point some minor noise is present but the rest is fine.

What about Galaxy tab s4? Is it the same as S6?

No idea - I came straight from the SM-T800.
tab s4 has a better screen

No, I'm not concinved there are any perfect displays. I still have one corner that's darker, honestly this experience has put me off Samsung. As soon as there's an Android tablet with better specs I'm done with this, I might be done with Samsung to be honest, the punch holes in their new phones are horrible and they're overpriced..
What's the best way to check the uniformaty of the panel in the S6? I don't believe I've got any issues but better safe than sorry!
Tab S4 much better will return the s6 I just bought as you can see grey in blackboard in so.e videos which you don't on the tab S4. Hopefully replacement will be better.
