black level? - T-Mobile Samsung Galaxy Note 3

Get Draw! from Play Store.
Mine is black like nothing under totally dark environment. It is not like Galaxy Nexus, S3, Note 2 that shows very faint light with few black pieces.
How is yours?

I don't like that app because of the status/control bar at the top. I have a backed up version of Kid Paint. I got it in the Amazon AppStore. It shows a completely black screen! The new version unfortunately has a bar on top as well. It sucks!
To Answer your question, this is the best contrast I've seen on an OLED ever. The Galaxy SII Epic 4G Touch I upgraded from had few bright spots you could see in complete darkness. This is so dark, it's amazing!

I took a picture with the lense covered and when I guess it on gallery, its like the phone is off. I kept tapping the screen to make sure it was still on. Really amazing Black.

[Q] Screen blackness

The Nexus S had a completely black screen - at night black was no different that if it was switched off. My GN appears to have slight screen glow in the backs. However, I thought they were both SAMOLED screens? Presume I am wrong? Can anyone explain?
/R
I noticed the same thing. I just assumed that not all sAMOLED screens are equal, and that the change in resolution could have been a cause. Maybe Samsung wasn't able to perfect it. Just speculation
It is pretty close though.

I was expecting this too and was a little dissapointed, was looking forward to having my night clock on and the only light coming from the screen to be the clock text but the whole screen has a slight glow to it
Same here, I wonder why is it like that. No bragging of true black anymore. Feels like step backwards.

The screen does do true black.
It's just the wallpaper isn't turned to black, it's made very dim.
The "slight glow" is the dim wallpaper if you look carefully.
Hmm, I made own 1x1 black picture for background. Still it isn't true black.

The same here, not nearly as black as my old Galaxy S
The blacks look black as black to me.
Mine seems pretty black. I've only had a Vibrant with SAMOLED before, and I think this is equivalent if not better. Sadly, I've got a small weird green dent on the pixels on the second quadrant though...
I've noticed this too. Definately not as dark as my Galaxy S2 was.
My blacks look as good as my GS2's did to my eye. When you guys open up the app drawer, it's not totally black behind the icons? I can't make out bezel or screen with blacks.
I've also noticed that the blacks aren't as black as on my Galaxy S. The blackness on the GS was even more noticeable since every colour displayed is eye-burstingly vivid. I do miss the true black but at least the general display is nicer on the GN than the GS.

I just used the night display mode on Gentle Alarm.
I put the Galaxy Nexus and Galaxy S2 side-by-side.
The Nexus definitely has a noticeable backlight compared to the S2.

Well the nexus doesn't use any backlight. Which is odd because there is a definite glow, I wonder if some screen tuning can remove it

Nigel Tufnel: It's like, how much more black could this be? and the answer is none. None more black.
I hate black screens I only like white ones....yea i said it!
My screen is as dark as midnight and is peferectly fine with me.
Can people please who say screen is completely black test the clock app in night mode in a perfectly dark place. I have a feeling this is not only in some of the phones but in all. Will contact support to verify this.
I think the black tint on the glass isn't as dark as it was on the nexus s. At least that's how it looks on my gnex.
When the screen is on for an AMOLED display, it's not "true black". If I remember correctly, there's a minimum voltage applied when the screen is on. Otherwise it would draw more power to switch the pixels from fully off to on. In other words, the GN might have some slightly different minimum voltage.

As mentioned earlier, the clock app doesn't use a pure black background. Rather, it uses an dark overlay over your wallpaper.
Also, the default background for apps has been changed to one that isn't pure black

[Q] Vertical tilting and blue tint

I apologize if my attempt at search terms didn't yet yield an answer that has already been posted.
On my Droid Charge if I tilted the phone up or down in portrait mode it would cause the screen to take on a blue hue. It turns out it was because of the screen protector I was using. Took it off, no problem.
However, I have no screen protector on my Galaxy Nexus, and I'm seeing the same thing occur. Since the screens are hardly the same (AMOLED+ vs AMOLED, different resolution, different size) I can't really tell if its normal. The demo model at my store was out of commission.
Anybody else notice this or is there something wrong with my screen? My friend said his doesn't do it, but I haven't seen it myself (he lives an hour away) and its possible he just isn't as picky as me
Thanks in advance.
I got the same thing on mines. Blue tint when not looking at screen straight.

when my buddy first got the Samsung Facinate, I remember noticing that weird blue tint. maybe it's a Samsung thing?
Voodoo color should come soon to fix that!

A blue tint of some sort, or cool colors in general are a product of the Super AMOLED screens, yes.
I don't think Voodoo Color would fix it in this respect, because I think it either has to do with the coating on the screen itself, or the way the light is refracting based on viewing angle.
I could be wrong...

[Q] White isn't truly white?

So I just picked up a Galaxy Nexus a few hours ago and I'm loving it.
One thing I've noticed though, in the SMS app and browser where white backgrounds are easily visible, the white isn't truly white. I can see little "discolourations", if you will, as if the screen was slightly wet in the white areas of the screen.
Is this a display fault or is this how the Galaxy Nexus' screen actually looks like? Coming from a Galaxy S I don't recall the screen displaying whites like that.
EDIT: Never mind, I turned off auto-brightness and cranked it up to max and the screen looks beautiful, the whites were a solid white. I was worried my display was crap! I'll leave this here in cause somebody else notices and wants to ask.
I had the same concern and the same revelation as soon as I got it home. Good to know I'm not the only one!
Ha ha glad I seen this I was having the same concern .

Note 2 screen defect on pure black screen in darkness

On my Galaxy Note 2, if I display a pure black screen in a completely dark room, I can see that first of all, the "black" is not really black, but somewhat pinkish. And second of all, there are "really black" dots and lines across what is supposed to be "pure black" but is somewhat pinkish (like i said). Also, this effect, of having a darker line, can also been seen with say, dark blue on screen in a completely dark room.
This effect is not noticeable when white or other colours are on screen. I'm really sorry but I can't show you a picture of this because obviously a screenshot captures the digital signal and not the physical output and I don't have a good enough camera to take pictures of what I'm saying in complete darkness.
Is this a defect or just an unavoidable "feature" of Samung AMOLED screens?
you did not use the search function: i personally wrote a huge amount of posts regarding this, also in the note1 section!
search for "black blotches" or take a look at my posts. really lots of them are about this!
in short:
its manufacturing dependant and its luck of the draw to get a "good" screen!
samsung lives with this as not many customers complain(ed) about it, as most of them do not even notice it!

Mine is pure back at full brightness when seen in a dark room (no pinkish hue or any line that you mention). And Note 2 screen doesn't even have the infamous black clipping/crushing issue like its predecessors! Blue colour also good, no issues for me.
No, it is definitely not an AMOLED feature or drawback (never seen it on any other AMOLEDs either)! Of all other aspects samsung SAMOLED screens are known to have the deepest blacks (with best contrast ratio). Sure, it sounds like you have a defective screen, and my suggestion would be to get it checked up at SC for replacement.
i also have a similar issue on my note 2. a black screen is not completely black, but a brownish black. And i can see 3 (or more) dots which are completely black.. i can see this only in a dark room, so normally this is not an issue. But when i read kindle in my bed with dark background, this really bothers me. initially i thought this was some smudge on the screen. im sad to hear that other people are also having this issue..
I had the black dots on my galaxy s2 ... but not my note ... The screen on my note has none of that sooooooo happy about that it really is just luck of the draw ....

Same issue here. But it does not bother me that much, and if I get it replaced, the next one might have worse issues.

im only worried if it will grow in time. like a dead pixel in an LCD screen, if this phenomenon spreads to the neighboring pixels over time, then its a very bad thing... otherwise, i am not bothered at all..
We need this thread each time there is a new phone which amoled screen? ..
The sgs2 has this as well as the sgs3 the note 1 etc.
it's not a defect, it's a limitation of amoled screen production.

Sorry, what you say here its not possible! EVERY amoled 'suffers' from this ('cause it CANNOT display 100% blacks, due to it's active matrix)! If you won't see it it's because of a wrong method or your eyes!

Black level question

Coming from a galaxy s2 which had pure blacks. If I looked at a black image in a pitch black room I almost could not tell it was on. Was very feint light output.
On my new note,
While having a beautiful display, given the same setup the blacks are not as black. The screen is brighter. Is that a defect?
Also noticed some areas weer a bit darker like blotches. For most uses this is not noticeable but when I read in the dark and use night mode along with a screen dining app to get it really dark, the background looks more dark brown then black

Coming from an S2 Skyrocket (LTE) which had horrible blacks and really bad splotches/blobs my note2 has much better blacks and no splotches that I've noticed and I have looked for them. I havent brought out the magnifying glass though..
