Black Level Color Depth not Deep Enough ?????

Hey There..
just got my s3 a few days ago, pebble blue vietnam june batch..
Ok now there has been a lot of discussion regarding screen issues like:
1. Tints
2. Ink spots/blothces
3. Black Crush
4. Black/other color Clipping
5. Depth of Black level
I dont have problem 1... Just 2-3 tiny ink spots, so even problem 2 is negligble....i dont have problem 3 and its can be tweaked with software even if one has it..problem 4 i dont care about much...
So, my area of concern is the 5th problem, i.e when compared to an sgs2 or sgs1 , i find that the black levels are not as deep and super black as the former two phones !
Its not really noticable in normal lighting..please check the following in a very dark room or completely dark room...
Using a pure black wallpaper (attached below or use ur own true black wallpaper) , just open it in gallery, it seems extremely dark grey (almost black) and u can tell where the display meets the bezel...
well, even on sgs2 n sgs1 on pure black background, u could see a little backlight, so not perfect black, which is understandable....so here is where the main problem comes...read below..
on a sgs2 or sgs1, When there is text or icons or other stuff over a pure black backgorund, this time the blacks appear black (obviously its due to contrast difference producing the illusion of super black) and one cannot tell where the screen border ends n the bezel starts, it just blends due to the super blacks! This is what i love and want !!
However, this is not the case with my sgs3, the damned blacks still are not perfect black & i can see where the screen borders end and distinguish the bezel & the screen , they dont blend beautifully!
to experience this, in a dark room, on any brightness level, preferably test at 30% screen brightness cause thats what we normally tend to use indoors, atleast i do...
please use this video: http://www.youtube.com/watch?v=KJO88Qhxwv4
(Thanks Tinderbox UK for the link)
or
play and high quality Dexter(Serial) video and see the part right before the intro theme where it says “SHOWTIME presents” (in white text) over a black blackground...
or
In youtube app when any video loads n the black screen comes with loading circle
or
use the pure black wallpaper with few icons on ur homescreen...
in the above cases, u should see pure black and u should not be able to tell where the screen n bezel borders meet..which is what u get on sgs1 n sgs2 screens..and i dont get this result on my sgs3 :-(
On sgs3, its almost black, but u can notice its very slightly gray ! so this is annoying to me since im so used to it appearing deeep black on the sgs1 n sgs2 !
--- So now what i need u guys to tell me is whether most sgs3 panels have this issue or is it just me ???
--- Will software tweaks like Supercurios upcoming “Display Expert” solve it by adding some black color depth adjustment ??
--- Should i take this to the Service Center? but prob is how will i show them the problem in a bright environment ?? and what if they tell me that the super amoled HD variant for the sgs3 is a new tech n differnt from the sgs1 n sgs2 screens and hence not as deep blacks ??
I WANT BLACK man !! i LOVED SuperAmoled cause if JET BLACK !! Help please!

this has been already experienced by many and so far none of the display experts has answered it or havent found the answer yet. in pitch dark environment the screen will look greyish black rather than pure black. i had the same on my s2 too but with a lesser margin.

hey Bala thnx fr replying, but wht im saying is tht, in ur gs3, dont u think its more grayish ?? iv listed the different conditions ...can u check n see?? im not talking about a plain pure black bckground which i agree is a lil grayish n is normal, but im talking bout black with other content on the screen....due to contrast differences n other colors from the non-black content, the black appears actual black as i had in sgs1 n sgs2, but in sgs3, it still does not Appear deep black

i dont thinks so mate, apart from the overall greyishness in full black conditions, i feel the blacks are good enough in images,video etc.
One more thing ,the feel of greyish black in pitch dark conditions may also be due to the fact that the screen border is dead black which makes us feel that the screen is not black enough. sgs2 didnt had this screen border afaik.

Are you looking at your phone the right way. You should be looking it at like this:

the black border is there always, you can see it from the home screen itself

I am having the exact same issue (or experiencing the exact same ''feature'') What i mean by this is that my SGS2 was pretty much pitch black, this one, not so much, I don't believe it's a ''problem'' though... probably made this way, although I REALLY liked the JET BLACK of the previous Super Amoleds...

yes i really wish the previous experience was there....but some ppl are saying they have real blacks with their sgs3 panels also...so i was wondering if its only for a certain batch of phones...
I want some big name devs to comment on this..if its software related n can be improved...then i wont fret about it so much...
some users in gnex forums said that maybe the voltage levels to the the 720p HD screens are lil higher and hence maybe the blacks are not completely dim, n emitting a lil light..
dam, i want some expert analysis on this !!

Depend on your way using smartphone . With me, almost time not using in dark inviroment, so I please with S3 screen .
Of course, display poor black in dark inviroment will be like dark/black gray . S1 seem better

The fact that Samsung still have this issue on the S3 indicate that it's a bigger problem that we(the Gnote Owners) anticipated,I was thinking that this problem was only localized to N7000.it's the same sh*t with Gnote but yours is just a bit less noticeable or Samsung tried working on it but failed

Damn ...so it seems llike most of Samsung's amoled HD displays have this issue...but still the poll on first page is 50-50...means some phones are perfct ...that's the annoying part...if all were with this issue I wouldn't be complaining that much...

This is true, so do you have an idea how we can tackle this problem, cos we need solution asap

I loved my SGS2 pure black screen...the next SGS4 will have black worse than HTC One XX of the year 2013 LOL did anybody contact author of display expert??? Maybe its possible to somehow lower the voltage of turned off pixels (black color) to do not emit to much light...

anyone NOT have red tinted blacks or smearing?

This is being discussed extensively in the international version forum. Those without red tinted blacks have smearing with grey on black colors, like in the menu screen. Those with red tinted blacks have little to no smearing. My device and a few other ATT S4 owners have confirmed that they have a red tint to mostly black screens in very low light. My question is, those of you with pitch black screens (even in a dark room), are you seeing any smearing or ghosting when scrolling in the menu screen? I want to see if the US variants actually have screens that don't have either issue.

Absolutely. I have the black crush pretty bad on mine. I went into AT&T today and checked the display models and both of them did it also. I made a video of it for those who don't know what we are talking about. https://www.youtube.com/watch?v=yL5TV8kuxac&feature=youtube_gdata_player

I take it you don't have red tinted blacks in very low ambient light?

No. Blacks look pretty black in a dark room.

I have a brand new S4 from Bell Mobility Canada. The smearing/clipping as well.
Any confirmed setting/etc that can be changed?
I first noticed it scrolling the settings menu....I remember seeing the S4 video clips where that same menu used to be white....

i got it too.

I have the smearing but it turns out that it's not as bad as I thought it'd be. I'll have to watch some videos when I get home but for now I think I'm okay with it.

If you have smearing, download Screen Adjuster and change the red blue and green to +5 or higher. Its been reported to fix the smearing and keep blacks black. For the red tint black, nothing you can do atm.

have the same problem on the phone with fido

There should be a software update for this

"bala_gamer" came up with this fix. Props to him. I agree, Samsung should have fixed this already. The "smearing" thread in the international S4 forum is getting a little out of control and Samsung just keeps dicking around, turning the red pixels on and off in each firmware iteration lol

I have an AT&T S4 and my black are 100% black. If I load a black image in the dark it looks as if the screen is off. How it should be

This actually helped to fix it, the issue was happening before and after the OTA, so it looks like the OTA didn't include anything to help that.
I had to set it higher though, is this hardware issue though?
I saw some ppl saying they didnt had the problem.

Everything ive read in the international S4 forum, except those very few who claim otherwise, suggest that either you have red tinted blacks OR you get smearing but have pure blacks...its one or the other. If someone really doesnt have either, i'd be surprised at this point. I thought maybe the US version was fixed, but no.
Its a hardware issue that seems to be addressable by software fixes, but if Samsung neglects it....well...thats a different story. Having to run Screen Adjustor and pushing the colors up is not without consequences. For one, i think its going to affect battery life. Someone reported that this fix made the slight pinkish tint on his screem even worse, so its not a perfect fix.

Per OP....I DO NOT have red tinted black. Phone is CRYSTAL clear and crisp.

[Q] New S4 - Screen issue

Hi,
Just got my i9505 and noticed some banding on one third of the screen (top). Specially in low light environment and with a white/light gray backround. A pure white image shows like a gradient.
Is this normal? Should I ask for an exchange?
Edit: Uploaded photo

While I don't have that phone I would say that it's not normal. Take it in.

Yes I had read that issue,have it too. Didn't know about the update though.
The main problem is this kind of gradient I have in the amoled screen. It's slightly perceptible but once you see it, can't stop looking at it.

Definitely not normal. Some devices do have that gradient with gray backgrounds (including mine), but it's much less noticeable than yours.

Top half of screen is dark

Hi all
I just bought a S4, and I noticed I had the purple smearing issue. I have now updated to the latest BMF8 rom which really solved the problem. But now I notice one issue, when I display a pure white background or a Grey background, I notice the top half of the screen is darker (pink tint) than the lower part which id yellowish...
it is the same no matter what screen brightness I set.. the top half is darker than the bottom... is anyone having this issue? my S3 does not have this problem...

Are you talking about a slight whitish tone on the top diaognal half of your screen and the lower half has this pinkish or purplelish tone on white or bage bg? Try taking a picture maybe?

I have updated the first post with screen shots. I dont know if you can see it but as I said, the whole top half is darker thsn the lower half.

I have just been to the Samsung kiosk in my home town... showed the phone to one of the reps and he confirmed the screen was darker on the top half... hopefully this gets changed tomorrow when I go to the phone shop...

I had same problem what @nm8 had. I sent my phone to warranty but only thing they did was a software update (what I did three times before sending it to there). Of course that didn't help, after I got my phone back it was even worse. I wrote petition to the shop from where I bought phone. Yesterday they announced to me that Samsung after-sales service will buy my phone back.
Right now I don't know that is this phone worth of buying again (would buy 32 GB version now). It's one of the most expensive phones in the market so I would like to get nearly perfect screen...

[Q] Is screen discolouration a fault?

Hello,
This is my first topic here, I have just bought a new S4, and the screen seems to have lines in it, when it is on a grey/dark screen, and is discolored on the bottom half.
Anyway, Please could you go into Settings > More > about device > software update. Now if you go in the dark, do you see discoloured patches on the bottom of the screen? (which are lighter than the rest). Please can you tell me which mode your screen is on, as then I can see if I can remove the problem by changing modes.
Also, It seems like when my screen is grey, there are lines all over the bottom half, that are slightly lighter than the rest of the screen.
Would you class this as a fault, as you can only see it in the dark, but I do use my phone in the dark a lot...
Do you think it is worth it to return it?
Also, if it is, do you think I should take it to the Samsung Service Center (I have full warranty, and Knox 0x0) or just return it to the seller
Thanks for any replies, I would be so greatful to anyone who helps
PS. it is not just in settings, it happens in any app that I use...

Well, first of all AMOLED technology isn't perfect and this is well known.
Most of users have a purple /pinkish tint on the bottom of the screen or top.
On mine aswell the bottom part of the screen is more pinkish or something like that, can be seem only on grey backgrounds bot i got used to it and doesn't bother me. Also i noticed when i keep brightness on very low level on white backgrounds like in play store i can see 1 or 2 slightly lighter horizontal lines.
To be honest doesn't bother me, all s4's i checked they all have some screen issues, because is AMOLED.

I have the same. That just something you have to live with.

Really? It doesn't seem very good that it should have lines across it tbh
I am quite disappointed - Does it also seem to have lines that look at bit like burn in, but can't be as the phone is brand new ,and i cant think of any time that i let burn in happen...

If they are visible even on high brightness then is a problem.
So if you can clearly see them on maximum brightness, then you can go and ask for a replacement

Bad news. Seems like these lines and discoluoration also happens on full brightness. Looks like I need a repair. I'll try and post some photos tomorrow...

I have the same lines, mostly visible on gray backgrounds. I can really see it on the weatherbug load screen. The one my eye sees the most is about 25% up the screen from the bottom, but when I stare for a while I can see a lot more. From what I've read, this is normal.

I dont get a full equal black screen either.Its like light is trying to get through in the bottom half of screen.Its more noticeable on lower brightness.
Never noticed it before....

Im sorry for tell ya but i think u have LCD screen troubles, like HERE

Every S4 has grey bands across the screen. The worst is the one about 25% up from bottom.
It's just a flaw of AMOLED screen

But this was not the case for S3 screen when I had it. So it is the new panels that have this problem.

You're right, the S3 screen was fine.
The new panels in the S4 are crap ( in my opinion)
Only advantage is 1080p, which for a phone is pointless (again, my opinion)

Hate to be the bearer of bad news, but I have absolutely no strange lines or differences in colour on any given background.
I only got mine a week ago though.

I'm sure you will mate, or you just haven't noticed it yet
I've had 7 different S4s and EVERY SINGLE ONE had banding in greys.

You are right I also had another s4 and the same thing. Probably if you go to the store and try the phones there all of them will have this. At first look with high brightness on it is not obvious but after looking carefully you will notice it.
