[Galaxy S 4 Q&A, Help & Troubleshooting] paddylaz:
It may LOOK washed out to you - but this is an AMOLED display, which is naturally very colour saturated.

If you compare the gs4 to an iphone 5 like I did just now, you'll see that even in Movie mode, the colours are a little MORE saturated than even the iphone 5 has to offer. The tint is a side-effect of this. IPS displays like the iphone may offer truer whites but amoled displays like the gs4 destroy them in terms of saturation and black levels.

It all depends on what you prefer on a phone.

In terms of the GS4, some people find the 'dynamic' and 'standard' modes vibrant and eye-pleasing - but they're not at all accurate and will exaggerated, innaccurate representations of your photos, videos etc. I have one photo of me in a yellow jumper (fashion mistake I know). When I have it on 'standard' it looks like I just came back from a two week holiday in Chernobyl. In movie mode, it looks exactly how it looks in real-life (i.e. still disgusting but accurate).

Here are a couple of links that describe it more:

I wish I have another camera to show you the difference between my iPhone and S4 ... The iPhone's screen is bright white compared to the yellow tint on my S4. If this is a "feature" then it's not really efficient now is it =\

Maybe there is a way I can manually edit the gamma, this should fix the problem I guess. Or just exchange it for another one.
[Galaxy S 4 Q&A, Help & Troubleshooting] paddylaz:
did you read ANY of my post?!

It's the trade off you pay for having perfect black levels and saturated colours.

The only way you're ever going to see perfect whites is if you get an iphone/htc one - e.g. an IPS display.

But then you're going to be stuck with 'blacks' that are actually grey. And that SUCKS.

People have differing opinions on which trade-off they'd rather have. Personally I'll take a slightly 'warmer' screen in return for having deep, inky blacks.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
Hmm I see, so the display type is the reason why the yellow tint appears eh ? Interesting, thanks for the links too, going to check them out.
[Galaxy S 4 Q&A, Help & Troubleshooting] paddylaz:
all screens will be slightly different from each other - but yes, amoled screens will almost always have either a slight YELLOW tint, or a slight BLUE tint - in other words, a slight exaggeration of one particular tone. If you have the time, do a google search and you'll see this was a common 'issue' flagged up on both the gs3 and gs2.

Your best bet is to do the following:

-set screen mode to MOVIE

-disable 'auto adjust screen tone'

-disable auto brightness.

You will never EVER see perfect whites on an amoled screen, and anyone who tells you they have them is lying out of their arse. Most reviews for the GS4 and also in the articles I linked you state that the GS4 is the most accurate amoled screen so far though.

If still disappointed, your best bet is the iphone5/htc one/nexus 4 etc
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
I think having an exaggerated blue tone is better than a yellow tone, in my own opinion.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
Anyone else having this issue ?

I noticed this playing around with the S4 in the store. Still, much better than the S3 white point.

bad yellow tint

Hi everyone,

I received my s4 last week and found it yellowish as well. I have read everything regarding the screen yellow tint and the fact that it's because of the type of screen. I was going to give up but my girlfriend got one today as well and the comparison is very clear: her whites are so much better!

I have tried to take photos of them, and it looks greenish on the shots but you can see the difference. FYI the screen are both using the same settings: auto brightness off, brightness at the maximum, both screen mode in adapt display (I have tried the movie mode without noticing a change).

Mine is on the right if you couldn't see. You can clearly see the difference in the colour and the quality of the screen. I also noticed that the viewing angle are way worse on mine, the phone takes a greenish colour.

Finally I have very strong smearing/ghosting as soon as the screen background is black. For example when I am in the settings, if I scroll up and down, the thin lines separating the sections actually disappear whilst the menu scrolls. The thicker separator get a purple line until the scolling stops. Once again, the smearing on my girlfriend's phone is existant but much less strong. The thin separators are still visible even while the phone is scrolling.

I am definitely bringing it back to the store tomorrow. I am very disappointed with the screen even though the phone is great. I wouldn't change for a One, just for a good one.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
This is exactly my problem, let me know what happens with you !
[Galaxy S 4 Q&A, Help & Troubleshooting] farhanali_:
I had the same yellow tint on screen and tried a few different firmwares thinking maybe its a software issue but nothing fixed it.

Picked up a new s4 last night and this one is perfect. The thing I noticed is the new one is assenbled in Vietnam and the old one

was assembled in China. Over all the build quality on the new one feels much better along with audio quality.

Maybe a quality control issues in some factories :confused::confused:

Cheers
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
Where does it say the location of assembly ? I want to see where mine is. Also, did you exchange your phone for a new one ? How did you convince them it was faulty ?
[Galaxy S 4 Q&A, Help & Troubleshooting] farhanali_:
You'll see it when you pull the battery, there should be a sticker there.

I am located in Toronto and we dont have any samsung stores here :rolleyes:

so i actually bought another one from this dealer i found on kijiji.

The new one was sealed and its from Hong Kong (but assembled in Vietnam)

Cheers
[Galaxy S 4 Q&A, Help & Troubleshooting] Light_Addict:
I looked at mine and it says made in Vietnam... But I would agree to say that there is a problem with quality control overall. My guess is that they need to produce as much as possible to avoid any shortage. I had the same problem with my Note 1 and could be bothered to change it, this time I won't let it go.

I will keep you posted.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
I had to go to another branch and thankfully they had a model with a white tone screen. I compared it there and they did indeed see the yellow-tone in my phone. I am getting a refund soon, it's not really worth all this trouble i'm fed up of the customer service experience with Samsung.
[Galaxy S 4 Q&A, Help & Troubleshooting] gtizon:
If you untick auto adjust screen tone, would it not consume more power?
[Galaxy S 4 Q&A, Help & Troubleshooting] Light_Addict:
So I went to the 3 different branches (vodafone) and they refused to acknowledge that the screen had a problem. I was rather pissed off by then and lost the tiny bit of manner I was willing to use. I decided to go straight to the samsung store and talked to the manager, he had a galaxy s4 and his screen was perfect with beautiful whites. He compared to the in-store devices and same, mine never looked that bad. I was happy because they could not say it was not the case. He said the device is faulty and that he think that it's an issue with the screen. He wasn't able to swap it on the spot as mine from vodafone which means that it is with all the carrier **** stuff... but he ordered one for me. He promised it will be fixed whether by them or vodafone.

Now I wait to see in what time frame I will get a new one. I will give you update on this thread when I know more.

Cheers

I went out to a few shops today as well and compared with several S4s on display. Conclusion - they all have a tint of one kidn or another. Most seemd to have a similar yellow tint to mine.

I honestly thinkl the majority of screen tint issues are not faulty sreens but are just flaws in the overall technology. AMOLED screens simply seem to be more susceptibel to precived tints. I feel slightly better about living with mine after seeing it is not just my phone and seems to be a characteristic of the device. You do get the blacks and popping colours OLED is famous for but the tint seems to be a trade off.

One thing that did make me feel better was having a look for the first time at an HTC One. I had headr so many great things about the screen I was expecting spectacular results. However I was fairly unimpressed, and prefer the S4 screen. I even found the HTC to be not very bright, but maybe this was just the ohone I was looking at as so many reviews bang on about how bright it is. I played a video clip and thought it dull and lacking in contrast compared to the S4, so overall I'll put up with the tint for now.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
I honestly just refunded the phone, not worth the hassle .. Good luck and keep us informed, Samsung should hear about this.

Well it's good that you're okay with it, but honestly I didn't pay for a yellow-tinted screen. I was promised crystal clear and accurate colors in the screen, not amazing "Blacks" as everyone is excited about here, yet all whites are yellows.
[Galaxy S 4 Q&A, Help & Troubleshooting] superioor:
I sure can relate to that. I will replace my Samsung and hope for a better batch/device. If it's still as laggy in the homescreen and the screen is like now I will replace it for a HTC One instead.
[Galaxy S 4 Q&A, Help & Troubleshooting] Light_Addict:
Well this is doing my head in. I went to the samsung's store today that said they would not exchange the device as they had no stock of Vodafone s4 though they agreed to write a statement saying that the screen as a tint and it was a different colour from other s4 devices in store.

I was confident that would help me but when I went to Vodafone they said that they could see it though it was not affecting the everyday use of the phone. They told me they will send the device for assessment and depending on the result they may exchange it. I refused and didn't have time to spare talking rubbish with these idiots. I called Vodafone help centre and explained my problem. They told me to go back to the store with samsung's letter and if they see a problem and refuse to act to give them a call on the spot.

I will pay vodafone another visit tomorrow with my device and my girlfriend's one, samsung letter and I will see what they come back with. If they refuse to swap it, I will call and see what happens. If nothing is resolved tomorrow I will cancel my contract.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
Let us know how it goes. I have refunded my S4's purchase. I will either wait another month before getting it or just wait for the S5 .. Or, as you mentioned, the HTC One !

It's really sad to see this ... We are the first ones to have this problem (that's being an early-adopter for ya !! ) and no one believes us. Thankfully my other branch believed my problem and gave me a full refund.

I hope you figure this out. In my opinion, I would have cancelled my contract already and went for another shop ... This is stupid of them !
[Galaxy S 4 Q&A, Help & Troubleshooting] toadsurfer:
Oh I don't know what to do. On the one hand my tint doesn't seem that bad but on the other I still notice it. Not sure it's worth trying to argue with the shop or not.

How bad is your tint? Is it subtle or obvious? One test is this xda app - the background on my phone is yellowy beige. Like parchment. Is it meant to be white?
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
What you're describing is what I went through. Instagram's white background is beige for me .. I can advise you one thing, if you are willing to go and argue with your shop, be ready to lose your S4 (unless you're patient). I snapped when arguing failed and just wanted a refund. Wasn't worth all this trouble tbh.
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
What happened bro ? update !
[Galaxy S 4 Q&A, Help & Troubleshooting] Light_Addict:
Well I tried all I could with Vodafone but they refused to swap it as they don't see the fault. So I went again to samsung and they told me that they will exchange it when they get new stock with Vodafone. The problem is that they don't know when this is going to happen and if anything happen to the phone in the meantime I won't get it exchanged... So for now I am using it with a filter on the screen which does help a bit.

I am disappointed that I couldn't get a screen as good as everyone else. The phone I get will be tested in store before taking it home...
[Galaxy S 4 Q&A, Help & Troubleshooting] ZaZu90:
Sorry to hear that ... Good luck, and I hope you get a white tone screen next time !!

Let me know if you do btw, because I refunded my purchase and holding off from any purchase until I guarantee that the S4 I will buy has a white tone, not a yellow-white tone .. But I'm also looking at other options such as the HTC One !

[Galaxy S 4 Q&A, Help & Troubleshooting] tclocki:
I got annoyed a bit coming from an android phone that uses an IPS screen (local phone so don't ask for the make as I seriously do not know it either LOL)... I found that these steps worked well for me in getting the whites that I've gotten used to:

-set screen mode to STANDARD

-disable 'auto adjust screen tone'

-disable auto brightness, set brightness to max

Now I'm a happy camper.
[Galaxy S 4 Q&A, Help & Troubleshooting] Edu616:
Mine when set to dynamic the tone is very warm but when i set it to standard it improves but not by much!!my s2 was really blueish!!when i hold my s4 flat in the hand it looks like it is suposed to be!! I think i also have that yellow tint!! But this s4 is the second that i have, the first one was getting really hot and it had a battery drain!! And this one now with a yellow tint !!!!this sucks
[Galaxy S 4 Q&A, Help & Troubleshooting] toadsurfer:
The screen on the s4 is really quite poor in my view. Colour tints, poor viewing angles and very below average video playback of dark scenes all add up for me. The screen completely lets down an otherwise impressive phone. The screen has been sub standard on all the s4s I have seen and used. If you want a screen of a standard you expect when paying this sort of money for a phone, I suggest you return it and get a different brand of phone and leave the S4 alone.

I'm selling mine and getting a One despite the fact I had originally written the One off for the smaller screen and no sd card.
[Galaxy S 4 Q&A, Help & Troubleshooting] Lulabby:
Do you guys have the uneven color problem between left and right or top and bottom, especially in white and grey backgrounds? Mine has the blue tint and the bottom of the phone compared to the top..
[Galaxy S 4 Q&A, Help & Troubleshooting] toadsurfer:
My screen demonstrates most of the rainbow if I tilt it around!

When held face on I just get the yellow tint but if I look closely on white backgrounds I get a mild purple/pink tint at top and bottom of the screen.
[Galaxy S 4 Q&A, Help & Troubleshooting] atir usman butt:
Next update will fixed all that hope so
[Galaxy S 4 Q&A, Help & Troubleshooting] toadsurfer:
I doubt it. Anyway if it was that easy to fix I think they would've fixed it by now. I think it's more likely to be the inherent inferiority of oled displays.

I think the screen is fine for the masses who probably won't care about the screen, but I got the s4 mainly for video playback and for me it's nowhere near good enough.
[Galaxy S 4 Q&A, Help & Troubleshooting] jodvova:
I have exactly the same, yellow tint in any of screen modes and if I tilt the phone 45 degrees it disappears.

Ive compared the screen colors with Nexus 10 by placing them side-by-side, I can clearly see S4's yellowish tint.

Thats crap basically :(
[Galaxy S 4 Q&A, Help & Troubleshooting] @rbiter:
Amazing. Amoled is still a very new technology and it is a mobile display. If accuracy is that big a concern some people should get an iPhone and see how faded it will look compared to any amoled screen. Putting your phone in movie or adobe rgb mode should help the accuracy of your screen a lot. No, the whites probably wont be white but the contrast and black levels are off the charts. I have one of samsungs high end plasmas from last year and it looks slightly yellow in movie mode but absolutely fantastic still. The whites can not get as white as they can in bright/white scenes because of auto brightness limiter. ABL is plasma manufacturers way of limiting power consumption and I suspect that amoled uses something similar because whites on amoled use a lot more power and being a mobile product limiting power with minimal compromises happens quite often. I suspect users of amoled tech need to get a low quality display or their home television professionally calibrated and a lot of these complaints will subside.

People are paying loads for this phone and expect performance as advertised. Having a yellow tint but off the charts "contrast and black levels" doesn't justify anything. I don't want to look at pictures with yellow clouds when they are supposed to be grey and white ...

I paid for a phone to be perfect in all colors, not just have amazing black contrasts .. seriously ?

[Galaxy S 4 Q&A, Help & Troubleshooting] puremind:
The yellow hue is due to the RGB calibration of the screen, which contains a bit too much green. i am sharign here some of the measurements I did in my Display Calibration Thread, which can be found here:

http://xdaforums.com/showthread.php?t=2268937

Summary:

Viewed directly, the display exhibits a green push in spite of near perfect color temperature - color temperature in film mode is slightls too warm (6410°K)

Viewing at an angle reduces green and red and increases blue

The most neutral white balances (Delta E of 2.8) can be obtained by viewing the screen at a 15° angle (you can do the test and notice how the green push disappears!)

The color temperature at this angle is further away from the 6500K standard than for direct viewing

but it is still more neutral

(shows the importance of RGB balance)
[Galaxy S 4 Q&A, Help & Troubleshooting] @rbiter:
Should a got an iPhone then? Seriously. It is not uncommon for many displays, mobile or full sized monitors to be off. I bet 95% of the people that complain have terrible looking TVs and monitors with colors way off. This and Samsung is known for having very color accurate displays on their plasmas and LCDs. Get the phine professionally calibrated if it matters that much. That said, perhaps I've been fortunate but I haven't had these issues on any cell phone. It is a mobile screen. It gets the job done, and very well I might add. My galaxy nexus had slight tellow tint but still looked awesome. My galaxy note2 with full rgb pixels is the best looking amoled, nay, best mobile screen I have owned. I expect my Google edition gs4 to be a downgrade overall with the pen tile matrix and higher resolution.

That's a great test you've done, thanks for sharing !!

And I do agree, tilting the phone does show the true white balance on the screen. Now if there's a way to calibrate the colors correctly, that'll be wonderful.

It's my second GS4 with the SAME exact problem. My brother got one the same day and it was flawless. Now I have to go directly to Samsung in order to try to exchange it, and we all know that can take a lot of time without the phone, which I can't have.
