Does the screen have a bluish tint in the whites similar to galaxy s3?

have they improved it? I can't find any close picture comparisons.. Thanks.

Looks better, but still there. I guess they're doing it to increase screen life or something, but absolutely hate that.
Once I installed Perseus on my Note II, I could hardly believe I'm looking at the same screen. Looks even better than iPhone 5 after calibration

yeah, but note 2 doesn't have pentile, doesn't it have a superior screen?

It does, yeah. But you can still see the bluish tint there. SIII/IV it's more greenish isn't it?
I have no idea why Samsung doesn't use RGB instead, is it because it isn't yet available for high PPI full HD screens?

I believe posters on here claimed cost reasons. too bad.. I prefer the overall design and build, screensize to handset ratio of the s4, but like the htc one screen..

That might not be apparent in normal vision though. S3 has noticeable graininess, but the pixel density on S4 should pretty much settle that IMO.
And I don't know if they took the screenshot with adobe RGB mode or saturated standard mode.
I love SAMOLED, but just wish if they could switch entirely to RGB. Wouldn't mind paying a few extra bucks either tbh if they implemented that on Note 3.

I don't think they can manufacture FHD 1080p yet. At least not in the amounts that the GS4 would demand at a reasonable price.

Yup, two issues: sharpness and color. It looks like the higher resolution overcame the less sharp drawback of pentile, but color tint looks is still there. need to verify what color mode the phone was in though.

welll, just got back from store. htc one's have multiple dipslay with different WB. but the s4 definitely had better WB in my eyes.

Why is this thread even open ? Amoleds will always have a bluish tint. LCDs always have better whites but suffer on black levels.

if you read my response, you'll see that the One has a more bluish tint than the S4.

Ink spots in S4 ?

A friend of mine used today a S4 and says it has some Ink spots.
Anyone else have Ink Spots?
.

You mean like these on the SGS3? I'd be surprised if the SGS4 didn't have them. The N2 did. My N2 may or may not have them because I've never looked at its display on a solid grey background with brightness turned down to zero in a dimly lit room as I don't typically use my phone on a solid grey background at zero brightness in a dimly lit room. There are always multi-page threads in every Galaxy with a SAMOLED display's forum talking about the "ink marks." Yet other then in the situation I described its never affected anyone in everyday use. People that this is going to freak out shouldn't buy a SAMOLED display.

But..... that's .00000000000000000000000009% of my typical usage. Why Samsung!?! Why!?!

What Barry said. Those blotches are pretty much standard. If you go "looking" for things, you could see backlight lines on perfectly white backgrounds on LCD too if you're REALLY looking for it. The thing is none of these are even nearly noticeable on daily usage. And neither do they interfere with your usage tbh.
That said, if you're buying the phone to view an entirely black image in a pitch dark room with low brightness, then avoid any AMOLED devices

GS4 has greatly reduced DC Bias. Much better contrast than the GS3 and Galaxy Nexus.

I remember having them on my old SGS3. Really annoyed me so I feel your pain.

It's called "mura" and is present on every Samsung device I have owned (GS2, Note, GS3, Note 2)

Yep, every single SAMOLED device, Samsung or not, has it AFAIK. Degrees might vary, but it's there.
http://forum.xda-developers.com/showthread.php?t=1365032
There are some members saying that apparently applying heat reduces the effect, not even gonna try it though. It is not that noticeable on my Note 2 even on low brightness/pitch black screen on pitch black room. S II users were the ones who had real torrid time with blotches.

Yeah, definitely don't try this. Can't remember where now but someone had this complaint about their Note II and went and used a heat gun on it. Suffice to say that "tiny annoyance" turned into a "I've got to call and get a replacement and this is going to be an awkward conversation". No idea if he got it replaced under warranty or not.

I didn't know.
Now i'm well informed, and will buy my S4 on May. :laugh:

I've had that on my SGS2, the screen was gorgeous so no worry.

I don't think even there are some black spots, anybody can recognize them
The black on S4 is tooooooooooooo black, much much much deeper black than Note 2
I can still see the luminance on Note 2 in dark room, not S4

it's normal for OLED displays, even the ps vita has it.

[Q] Black level

Searched google and couldn't find user input on the black level. According to that early test by a Chinese site they found black level to be extremely good. Here's the image

Now as the phones reaching users can anyone confirm in pitch black the amoled output? To me that's the most impressive improvement dating back to when amoled first went HD on the galaxy nexus and lost that level of output.

Yes, it is totally black. Way better than S3 and Note 2.

The blacks are the best I've ever seen.
The pixels are completely off, as opposed to previous amoled screens where there was still a light glow.

Wanted to give this Q too I had previously SGS2 and SGS3 is it even better than SGS2 display in the case of black displaying? I was very satisfied with SGS2 blacks... THX

It's much better., Infact it''s impossible to get better blacks as the pixels are completely off.
I was always disappointed with previous phones as in a dark room once your eyes focused the blacks would look light grey and you could see blotches and streaks.
On the s4 you see nothing at all.
If you switch your phone on in the dark all you see is the samsung logo on the screen, nothing else.

perfect THX for response I hope that will have zero stuck/dead pixels

That's amazing. It's pretty poor form that all reviews as far as I'm aware have stated the previous amoleds with that slight glow as infinite black.
Anyway the S4 finally has something I'm really jealous of now. Another question similarly relating, does the brightness go lower than the S3?
?????? Galaxy S3 ??????

I think something is wrong with mine. I have the Galaxy S3 and I would say it's a really dark gray, not quite black. But on the S4, I'd say it has a reddish tint to it when I have it all black in a dark room. I may try and take a picture of it tonight.

I think its every device or atleast very common, but most people havent notice it (atleast not yet) . Ive come to realize its software related so im not freaking out yet. Just posted this in the ATT forums: http://forum.xda-developers.com/showpost.php?p=40841213&postcount=104

It is honestly that black that when I was waiting on a video to buffer in my pitch black room that it looked like the blue circle was floating!! literaly no light on screen apart from the blue circle. It actually looks really cool lol

It is brighter than S3. :good:

It is perfectly black unless you suffer from the bug I posted about here: http://forum.xda-developers.com/showthread.php?t=2256651 .

its pitch black, i tried finding some ink spots/ blotches and black level last night but failed miserably

There is a comparison between S3 and S4 black/grey scale in this video, FFW to 17:10 (or watch the whole unboxing and comparison to HTC One video if you want).
You may have seen this by now, but if not it might answer some of your questions.

Yellow tint issue on S4's screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?

Mine doesn't look like that, sorry. But I have lag. ):

Is it just in Chrome?
Try Chrome Settings ---> Developer Tools ---> Uncheck 'Enable Tilt Scrolling'

@raqball nope this is found everywhere, even instagram and facebook.

Ah, no clue then sorry..

@raqball can you do a quick check with yours, similar to the one I did and let me know what you get ?

Go to settings display screenmode and use something else other than adapt display. Im currently using dynamic and my tint is gone.
ATT S4 Rooted. Beastin.
4.2.2

I had it on standard all this time (including screenshot) .. Putting it on dynamic gives the same result :

Damn I was hoping it was that because it fixed it for me. Maybe a hardware issue?

@stevehkim I'm not sure tbh .. thanks for the suggestion though. It's quite annoying after I realised that it exists ... Didn't bother me before I noticed it :\

I found an app called Screen Adjuster but its not really efficient.

I had this with my S3 and got used to it. I was told in those forums that this is just how these AMOLED screens are made.

My display is perfectly white though... Side by side comparisons between the Note II, Microsoft Surface RT (perfect white display), and a Sony HDTV. My S4 beats or meets them all.

Can you post a picture comparing your screen to a laptop's screen ? I just want to see how different it looks. Also, do you suggest I return it to the store and get another one ?

I would return it rather than regretting it later. It defiantly doesn't look right.

Acer 24" LCD Monitor vs S4
I'll do one of my Surface or TV later.
I made a Pure White image to use for testing on the S4, use it instead of Chrome which uses a grey color in it's UI and for some reason the S4 screen brightness dims on Chrome automatically (and you can't change it). Download it if you want to do comparisons again.

Thanks for doing this, do you notice any yellowish tint or is yours bright white ? ...Yeah I tried a white BG not in chrome and this is what I got :

Can we all agree ? The Screen is FANTASTIC! (And here's some videos to prove it)

Just wanted to voice how great this screen really is! I'm a G3, Note 3, S5, S4, Note 2 -
I was so excited for the G3 and then the screen on that thing had no VIVID colors! What a huge disappointment - it went back.
If you'd like to see how great this screen really is, TURN up the brightness, go here to this post http://forum.xda-developers.com/showpost.php?p=56100084&postcount=14 and grab those videos!!
Killer!

Samsung and Apple both have the best screens on mobile products. The LG G3's (QHD 2560x1440) screen is amazing but it uses IPS LCD screen while the Galaxy note 4 uses SuperAMOLED 2D screen.

I agree I had g3 and fixed my self to like it this screen blows it out the water

To be fair, the colors on Samsung devices (by default) are vivid, but not accurate. Not sure how accurate the G3 is, but Apple screens are generally quite a bit more accurate than Samsung screens.
From what I've read the Note 4 has the option to use vivid or accurate color rendering, the accurate is at least as good as the iPhone 6 (plus the option to have the colors really pop.)

im excited to see screen today!!! g3 has good screen i think (thats about it imo though but good screen) so we will see!

So excited!!!!
So which wallpaper will anyone be using? Stock Note 4 or anything you have prepared to use for it? I'm spending so much time browsing 2560x2560 wallpapers but can't really decide which to choose.

Anandtech, Displaymate and others state the color coverage is the best of any device. Depends on the setting. Vivid is still an option.

i do love this screen, but i very slightly see what some people said about the upper right hand portion of the screen having more of a reddish hue than the rest. mine has that, but it's pretty slight and only noticable on white screens like in the menus, so i don't care much. everything else about the phone works perfectly so i'm happy!

Oh wow! I love it. It looks awesome on the Note 4. Thanks for bringing that to my attention. :good: :good:

There appears to be some G3 owners in denial that their power hogging, low contrast displayed device is better and the N4 is a laggy while the G3 is super fast. This in contradiction of most reviews and my own experience.
G3 is a good device, but the display is a more than usual resource killer.
