While comparing two att s4's running LCD test I noticed one displayed light through pure black while the other showed no difference between pure black and off. This was done in a pitch black room. I cannot see the difference when light is present only in pitch black.

The screen is OLED, not LCD so all black in OLED is "no power" to pixels. This the opposite of LCD where the pixels are all on and are blocking the backlight. There is no backlight in OLED, the pixels themselves are lit. That is why OLED is blacker, but LCD can be made brighter - in general.
I understand how OLED works and I was not comparing it to an LCD. What I'm saying is while comparing two att Samsung Galaxy s4's, one of them displayed true black while the other did not making it noticeable in a pitch black room.

It does, but not that much. Watch the video in this post. Towards the end, the reviewer does a crush comparison with the s3
I tested my own display with the same gradient chart shes using and it looks the same I can see to 3 on that chart. Ive also ome across some netflix movies where the shadows clip on the S4, but not on my LCD. Again, nothing major, but its still there.....atleast on my device.
A little here, has been a thing on every OLED/AMOLED device I've ever owned.
No biggie.

Also when brightness is low and I'm on settings when I'm scrolling down I can see as if the fonts is bleeding and colors are a bit pinkish. Normal or should I exchange?

There are some of us, me included, who see a red tint to blacks in a dark room. The red subpixels seem to stay on. Some folks say they have pure blacks even in the dark.
Now I dont see pink text when scrolling, but maybe your eyes are sensitive enough to see the red from blacks bleed into the text.
Do you see a red tint in blacks in low light? If so, that might explain the pink text
Sad to say, the S4 actually clips more than my galaxy nexus. A clear indication of this is in Phase Beam live wallpaper. The S4 has a trouble doing a smooth gradient on the purple shadow on the lower right hand of the wallpaper. It just shows a blocky purple shape in this area. The Gnex shows a nice gradient. Bit of a disappointment
Made a video of it. Went into AT&T today and checked the display models and both did the same thing. Might be s big problem. https://www.youtube.com/watch?v=yL5TV8kuxac&feature=youtube_gdata_player

For those of you who have or have seen the note 3 in person. Can you confirm if the black version of the not 3 is actually black, or is it more like the s4 and looks more blueish?
The only reason I'm considering a white one is because I don't want a blueish phone like the s3 or s4.

It is black, not black mist... it looks black.
Yeah it definitely looks black to me, glad I got the black :thumbup:

I used one last weekend, very very black, no blue crap
Mine looks more grey on front top and bottom bezel.
I just compared mine with my "black" Mega 6.3 and a SGS2, The S2 is really dark black, the Note3 a tad lighter because of the brushed metal look and my Mega 6.3 is the same as a "black" metal grey S4.
It is black, yes
I guess I'm getting the black one then. No offense to white, black phones are just sexy. I have the silver HTC one for T-Mobile and every day I wish I had the black one, every day.

Hi
Currently got an S4 and I'm looking to replace it as I use it a lot for movie watching and magazine reading and the slight yellow tint to the s4 screen really annoys me.
Seeing as the note 3 has a similar screen, but just slightly larger, can people confirm whether the note 3 suffers the same inaccurate whites/yellow tint?
Thanks!

I don't know what yellow tint you're talking about but my S4 didn't have it nor does my N3. I dont use adapt display and my screen mode is set to dynamic

It's when viewing whites my s4 has a decidedly warm colour to it so whites look dirty and slightly yellowy. It's a well reported characteristic of the s4 although probably didn't affect every single one.
Just want to know if the note 3 solves this by having cool whites as opposed to warm. Maybe personal preference but I much prefer a cooler display.
Sent from my GT-I9505 using xda app-developers app
I have noted it but just in the movie mode, in dynamic and standard it seems a little bluer to me but it's personal opinion. But I have to say damn this is a beautiful display worth the choice of the phone by itself
Sent from my SM-N900 using xda app-developers app
That's good. As long as some of the modes have a cooler tint I'll be happy. The green/yellow tinge is just a bugbear of mine.
Thanks for the replies.

I've had a white one since november and its been flawless. No case either. No ocd issues. Guess it depends on the environment. I also like the white because it shows of the size of your screen better. This is the first white phone I have had and was worried i might not like it but those worries disappeared as soon as i open the box.

Definitely white. I love my white G2, looks way more elegant and distinctive.
I've had the unfortunate opportunity of owning both a black, and a white one which I got to replace my old one. The white definitely looks better and you can't see the fingerprints, also it looks more "premium" according to my family members.

I thought so too till I realized it's a fingerprint magnet, the white is better at covering that up.

white.
less fingerprints. Don't see much of other dirt stuff.
and best of all it looks different than all the blackies out ther.
White here as well. Looks cleaner than black even with all the fingerprints.

Looked at both and I picked black I have had a white note 1 and note 2 so I picked Black this timeso I can't be ocd about the black line around the screen being noticeable on the white model. No regrets on picking black

I have a black one and my best friend got a white one. I dislike the black stripe between the bezel and the screen on the white one... but except that the white is more impressive and hides fingerprints perfectly also the screenprotector is invisible on the white... so if you like the color white all the way:good:
I keep a soft touch case on my black one because of the horrible fingerprint problem. So really it didn't matter to me what color I got. Case helps you to find the power key easier too.
