[Q] bought a Galaxy SII, is this normal on the amoled? - Galaxy S II General

hey guys so i have this phone and i like it, not awsome all the way, but its great so far, astonish performance and an OK camera, anyways heres what ive noticed and i dont wanna send it back before im sure its a problem:
-When i view its screen turned on from different angles the color hue slightly changes a bit to blue, this is most noticeable in bright images with alot of white level for example, is such thing normal?
Also is there any particular thing i should look for to know if its working properly or not? ive heard alot of ppl had problems with the screen, what are the steps that i need to take to check if mine has or does not have the same problems.
Thanks in advance!

ill be getting my S2 tomorrow but from what i understand this is normal on the phones ive owned in the past

True ... when screen are turned and seen from different angles, the color hue slightly changes a bit to blue and that's normal.
But on my SGS2 no yellowish colors or black spots.

OP, the slight bluish hint is normal.
Also normal is some moderate banding on plain gray background.
Also normal is moderate yellowish left side. To check how severely your screen is effected, switch OFF orientation sensor, display a full screen gray image on about 25-50% brightness, look at it in portrait orientation, than flip the phone 180 degrees, so it is upside down. Do a few flips, you will notice the difference in colors on the left and the right sides. Most people do not see it by just looking at the image, they need a real precise side by side comparison like what I just described.
All these issues in moderation are normal for Amoled. What is not normal is dead pixels or damaged screens underneath the glass, but these issues are rare.

Pity you dont have a search button .

Display light leakage on top corners of my X1 Screen? anyone?

Hi,
When I dispay a black background color on my X1 for example the pannel screen while it is switching to a different pannel or standard pannel I see a bit of light leakage on the top 2 corners of the screen from each side. A bit white, if you understand what i mean.
Does anyone notice that?
Thanks for the info
Yep I notice it too. Probably a case of bad backlight LED placement.
This screen doesn't seem to have as good a contrast ratio (black levels) as the one on the Touch Pro.
it's rather massive. Its even visible on camera mode when you have wide-mode off.
I hate living with imperfection.
How bad is it on your device?
I have to say its not visible when other colors than black are displayed
I'm probably seeing the same thing as you are - two bright areas on the top/left edge of the display.
The light is "leaking" because the display contrast isn't high enough and the screen assembly is a bit thin.
It's something I can live with, but I do wish SE had sourced for a better display. HTC has raised the bar since Diamond and Raphael, and this one is pretty good for a Windows Mobile device, but there are tons of even better screens out there - think Japanese super-keitais.
humm.. I was trying to look for the light leakage but I can't really seem to see it.... perhaps you could post some photos of what it actually looks like?
yup, it's there
don't see any leakage on mine...
I tried one in the shop and the screen was tilting left a little bit. Also the flip was a bit loose even in closed. Any comfirmation?
I'm pretty sure all devices have the same leakage problem. Just put on a pure black screen and look for the white cones decending from the top corners.
It's because of the led's behind the screen I guess
honestly, there's very little (leakage, short of better term) if not none. If you have seen TouchPro, it leaks like crazy...
Leakage is pretty terrible, no doubt about it. Wonder if this fault is only on some handsets?

My TP don't have this at all. Virtually no leakage. Pretty much solid black even in pitch black environment. Contrast and viewing angles are excellent. One of the best if not the best screen I've seen to date. Seems like they're using 8 bit panel instead of 6 bit TN panel. The latter have terrible contrast and viewing angle as standard.
lucky if u only seen it on top corners, mine are on all corners!
i don't see any leakage... went into a pitch black room and pressed the panel button and i see no white light coming out of the corners...

then you must have a rare TP, all the TP owners in Singapore reported to have the same leakage. that's if we are talking about the same thing with regards to light leakage...
Hi,
2 days ago a friend of me and me bougt this moblie,
yesterday i gave it back to the store, cause i've seen the white
leakage on my display too, on the devise of my friend its ok.
today I'll get a new one. Hope its ok there....
Thought it was damage or so....

Maybe I'm missing the point here. Do you mind posting a screen shot of the issue so we can be on the same boat? Now you've got me curious.
I'll try and post a photo when I get home later, mine is mainly in the bottom left half of the screen and it's really noticeable and distracting when viewing something dark.
Hmmm, I've definitely noticed leakage on my xperia, in the bottom left hand corner when in landscape.
I had a Touch Pro for a few weeks before I got the xperia, and the screen on that was flawless. I might give vodafone a ring and see if I can get it replaced...
Don't forget to switch the display brightness to full to be able to observe the leakage. When I watch the Bond trailer I can definitely see the leakage on the top corners when there is a black background in the beginning. It's rather distrubing but I do believe that all devices have that in some sort of extent. I think you just have to get used to it and live with it.

Hmmm!!?? purple-ish screen tint on lowest brightness on my new NS

Well I used to cause a big fit about the N1's HTC would warranty swap me because of this issue. The first N1 I purchased didnt have this problem. I just bought the NS today and right away I noticed the same exact issue. Is it safe to say that maybe this should be considered a normality rather than a defect?
Its actually the Amoled tech itself...It cant reproduce whites perfectly so they come out cool....thats why its off a bit but in return you get exact blacks
Lcd's are opposite...you get real whites but no real blacks.
It shows up in certain shades of grey, like in contacts and in clock dimmed while set on lowest brightness setting. The whites and other colors display fine.
Yeah i saw that too but thats the OS thats doing that so you should be cool
Is it either on the bottom or top? I have watched a YouTube unboxing video clip says that when you browse with your nexus s to the top of the page, or the the lowest of the page, it will actually dimmed darker. This is to let you know you have reached the lowest or highest of the page. You couldn't scroll anymore .
Sent from my Nexus One using XDA App
No, it has nothing to do with scrolling. It's exactly what I've said. Also I'm pretty positive its not a software issue. It's definitely the display. It must be either new materials Samsung is using for there displays or a calibration issue!
I also noticed this today, the purplish tint while on lowest screen brightness in a very dark room. If you bump up the brightness slightly, it goes away.
Nothin for me. No tint.
For me when I have the screen off I notice there is a purple tint to it compared to say a vibrant maybe that is the cause of you're problem
what i'm speaking of shows only while the screen is on.

This is right on the money. Same exact issue with my N1 and now i see it with the NS. I notice this on the N1's because my very 1st purchased unit displayed perfectly without any kind of discoloration after dimming the brighness below 50%. Soon after I warranty exchanged that unit for another, I recieved one with the tint issue. After I exchanged a couple more times, I recieved another without the tint issue but the touchscreen problem was much worse than the others i've had so i sent that one in. After that, i havent received one without the tint problem yet. I bought the NS expecting not to see this problem again and lo and behold, it surfaced as soon as i dimmed below 50%.
I checked out the demo phones, and every one had it on the lowest brightness setting. I think it has something to do with the new colors in the OS. If everything was black, it would be harder to see, so they use a little purple to differentiate when on a low brightness setting. You dont have to turn the brightness up much to make it go away

The issue I'm speaking about, it doesn't literally "go away" in the manner you might be thinking. Its just that certain shades of greys are affected by it. Here's how to test for it, goto a dimmly lighted area and set the brightness thru the power widget to highest. Next, goto the dialpad on your NS, and notice the bar topright below the menu tabs, it should be grey. Now go back to your power widget and switch brightness to lowest setting. Go back to the dialpad and look at that bar again. It still should remain grey no matter how I adjust the brightness levels, but instead it'll shift to a light purplish hue.

It's because of the amoled screen uses the pentile sub pixel layout. I thought this was well known. All Samsung amoled screens do this as the all use pentile sub pixel layout, which many people hate as the feel its not as good as the true 3 sub pixel layout screens. And It's true it is not as good, but I still prefer it over non amoled screens, crap pentile and all.

Yes I know about the subixel stuff with the amoled displays, but I have to disagree with you as far as all of them display this way. As I've mentioned before, I've had 2 N1's without this issue. I'm gonna go back to BB to see if they can open a couple so that I can do some comparisons.
As I said, mine is this way too, but went to 2 BB's tonight and checked out the demo models at each store. They both had the weird purple tint as well, on those few shades of gray, like you pointed out. I also watched the Engadget video review and could see the purples on their phone too. I think all the NS's are like this, just the way the screen is. Perhaps in a software update, they could tweak the colors a bit and fix it.

actually
this is not true. i had to go around 4 Galaxy S screens and finally i was able to find one without pinkish color in it in low brightness.
if you want to tell if you have pinkish hue. download a solid dark gray wallpaper. turn the brightness to low. if you see it pink. then you have defective screen. i repeat. its a defective screen. dont justify your self with it.
i went through 4 galaxy S and i was able to find one where white is actually white and closer the the cool blue. not a friggin pink
and its not amoled screen either. the iphone 4 is same issue. go to macrumors forum and check for your self.
i went through like 6 iphones to get one with cool blue and no yellow tint in it.
the difference is light and day now when i compare my iphone 4 to my other friends.
if you have an OCD with this " because i do. i have OCD for light leakage, same black level the whole screen, yellow/pink tint on the screen in low settings "
the whole phone to me is nothing but a big screen. if they f*** that up. then its useless

its not a software problem.
its hardware issue. when my phone with pinkish tint along with my brother one didnt have one, i thought it could be a software issue, and we even both implimented the voodoo fix : galaxy S : and still looked different.
its a hardware issue. and i really think you need to change your phone. because if you are like me, who cares alot about his phone, then once you see someone with a nexus S and you compare the whites and the gray colors on both phones. you will be one sad panda.
hell put the brightness up to the max even. you will still see the difference in white level between a pinkish/yellow tint screen and cool blue one. its not even funny :/
Yes I'm definitely OCD'd on this issue lol. I'm still not total convinced that this a defect yet. Ill be going to a few BB's today to do some comparisons. If I do find one without the tint, then cot dammit, shame on Samsung for allowing this to slip thru on these screens again! Ill report my findings later.
My NS suffers from this horribly on top of the bad touchscreen issues it also has. Def. a defective unit

Another display issue?

My display had purple tint and I changed the phone today and got a new one. Its better now and significany less pink color.
Also I now discovered something that the pink tint is only visible when u look at the screen 90 degrees. If u tilt the phone a little (5-10 degrees) to left-right or up-down and view like that the color turns normal (like my year old sgs).
It made me realise that this is a screen coating issue (maybe coating causes polarisation). So do u think this will go away with the time of use?
When I turn off the screen and check it under light by tilting I can see a little purple glare.
What do u think?
Do you have this on your phones?
My sgs, when the screen is off if you look the screen under light has a bluish color/glare.
However sgs2 when I look under light,screen turned off has a purple glare.

he didn't need to taken it off
mine was without screen protector and there was purple glare on screen
now I'm really happy because it's not just me who has this purple glare on screen
this does not matter I like this phone
I find the problem when it is directly under bright light only...even when bright sunlight, it doesn't give me the glare...so it is not really a problem, I don't have a bright light in my room lol
Purple glare is not a problem but it causes phone to display purplish whites and greys when the screen brightness at low. At night, If I look 90 degrees to phone whites are creamy greys have a pink hue however when I view the screen from a little different angle (if i tilt like 5 degrees) whites are cool and greys are perfect.
Well maybe my sgs has a blue tint and cool colors that's why I feel a huge difference. Cuz when I compared my iPod touch 2nd Gen. IPod's color is more pinkish tthan my sgs2.
I don't have screen protector yet but I was hoping putting one would fix that purplish tint issue. So it doesn't.

I meant that I do not see any tint on my screen.
I have a Bell version, made in China.
The only thing that is bothering me is grease fingerprints marks.
Otherwise this is the best screen on market right now.

I have bell too. Where did you get your phone? I would like to go to the store that u bought to compare mine. Phones in the store that i got mine all have the same issue. This is my 3rd phone from the same store and they are already sick of me going there to change everyday. Maybe it's a batch problem. Are u in Toronto? If u are could u tell me the store name?
I've bought it in the TBooth in Eaton center
I checked all the phones in eaton center and they all have different screens. Mostly they have yellowish tint. One phone in future shop was worst than mine(purple)
One of the 6 display phones in bell had a perfect screen. Which made me hesitate about changing my phone. What are the odds to get a perfect screen?
The phones which have yellow tint their colors look pale to me. Only problem is mine, certain grays look purplish. Such as the status bar buttons. In a dark room with 0 brightness they have a purple tint.
when I tilt the phone that purplish color goes away.
What color the pull down status bar buttons should look like? What is your color?
Dude there are always will be some imperfection in any device.
Stop nitpicking, enjoy your phone.

[Q] Screen colors uneven?? Normal?

Hi all,
I know there is alot of discussions surrounding yellow tinting and yellow colors , or uneven screens on S2 , S3.
But I haven't seen much of it talked about for the S4.
My S4 has slightly darker colors on the top of the phone. The difference is quite visible on a white background, and very visible on a grey background.
Here some photos showing the issue:
From the naked eye the differences are not as great as shown on the photos. however it is there. sometimes its darker sometimes its not so much darker. but visible and very evident that the screen colors are not even.
Is there any problem with this? Do I need to take it to Samsung for repair?
When I'm using google for example the top of the screen is like bluish....and the other half of the screen is white.
Because I haven't seen many discuss about this issue, I'm wondering whether its just mine?
You have a defective screen.
Take it back for repair or replacement

Screen tint and viewing angles questions and opinions please

Ok well I would like to get peoples feedback and opinions on their screens.
My story. Broke my GNote II instead of paying to replace LCD decided to upgrade with my carrier.
First Note 3 I bought was bright with nice whites and great viewing angles. But it has the dreaded pinkinsh purple screen tint issue in the lower 3rd of the screen more so on the right side. This is subtle and is less evident in brighter conditions or higher screen brightness. At low brightness and in dark environments it is particularly visible on white and grey backgrounds. Went to store to exchange and they refused given they could not see the defect. I came online here searched around and it seems this has been an issue on the GS4 and people have mentioned it on the new Note 3.
Convinced my carrier to send me a replacement and I will return the original to them. Well got the replacement 3-4 days ago. The unit seems quite different. First off the screen is overall a bit more yellow at face on viewing angles and perhaps a hair less bright at similar settings though hard to tell. The bottom is not color shifted puple. The screen color is more homogenous. However the viewing angles are completely different. Here while the brightness stays goo dlike the first when angling the screen, the colors shift to a more aqua color with minor angle variation. (guessing 20-30*) whereas the original unit has virtually no color shift at almost 90*.
I probably have to send back a unit in the coming day or 2 and make a final decision. In theory I could try to ask for a third model, however it was with a lot of difficulty and threats to leave my carrier that they relented in the first replacement. SO I likely will have to stick with one of these or return both and use my somewhat broken note 2 and wait for something else.
I am wondering if any of you out here have similar pink/purple tint issues at one end of your screen. Or if you have issues with significant white color shift when angling your screen more than 30* in either portrait or landscape. Also if good or bad can you check build date on your phone (should be under battery). FInally did you or will you replace it? Was replacement better or worse?
Also if in my shoes would you go for the better looking screen with the pink issue or the more consistent looking screen that is a bit more blue yellow.
Thanks!

I know you did and I posted some long posts there and the thread kind of died.
I have some specific questions here as well as asking what I should do in my case.
I had a note 2 and remember there being perseus kernel and with STweaks one could shift color etc and make it how you like. I am thinking going with the more uniform color model as I am sure the slight yellow tint can be corrected and the blue tint on viewing angles is no worse than my note 2 looking back so I will get used to it I imagine. That said the first screen really has great screen but the purplish pink right bottom corner bugs me on white and grey screens ( not noticeable on high brightness though) and often reading on websites etc indoors I notice it enough that it bugs me.....
So for anyone who cares here is an update on my plan. The more uniform note 3 is more yellow/green tinted whites compared to the other one that is whiter/redder. That said if I use one of these screen filter style apps that exist in the play store, I can modify the overall screen into however I like.
Downside is that it means a persistently running app to do it with whatever effect on screen longevity and battery.
Now on my Note 2 which is also yellower, I was running perseus kernel and the s tweaks app and was able at the kernel level to modify the color to get better whites. I imagine it is only a matter of time before someone can do that for our note 3. I can handle the viewing angle color shift as the device is in my hand and not on a table when i use it where it might be off angle viewing by a large amount. And even then, the tinting of white has a bluish shift and now worse than a yellowing shift my wifes iphone has off angle or my note 2 did.
Would love tohear from others and what their screens are like and or developers who might have the means of modifying color at kernel level the way Andreilux did on the note 2
I checked almost 10 note 3s bkack n white as well..and found only 1 set.it has no yellow tint and no gray lining.

You checked 13 notes and 12 of them were either yellow tint or what gray lining issue?
How did you manage to check so many.
Can you check the following. Look at the phone screen face on the tilt either up down or side to side about 30 degrees and tell me if the white on the screen turns bluish.
One of my phones does this and has the yellower whites. The other does not and has better whites but has some purplish discoloration in the lower right part of the phone.
Any one here try a new kernel from the android development sections?
Some of them talk about being able to modify screen color. Am wondering if this can be a fix for my issues.
