I think what that app does is it adds an extra layer of color on top of the screen. So... your blacks got more gray :) .
[Galaxy Note GT-N7000 General] edgarson:
yeah, that app turns super amoled into a bad, kinda LCD type screen where blacks are the worst colours. Great solution!

Here it is.
[Galaxy Note GT-N7000 General] borich:
PA utacka doesn't solve the problem. They simply throw away the mdnie settings and this is the results. clipping at 1.

In near black test picture you should see a PERFECT fade to black until 7 or 8 gradient, than pure black.
[Galaxy Note GT-N7000 General] nigi73:
Exactly as on my poor lcd. 6 is last number and then blackish. But transition is smooth and nice.
[Galaxy Note GT-N7000 General] Formhault:
Oh... So that's what happens if the mDNIe is thrown away...

Well, it clips at 1, not at 4... That's a lot better :) . The blacks (level 0) is still black, right?

Actually, no. 0-7 or 8 should be all black? No. 0 should be black. 1-21 should be gray (from very dark to very light). Kind of like if you display the gamma test image on any monitor or laptop.
[Galaxy Note GT-N7000 General] borich:
if you watch this image on a computer with good calibration, you can see only until 6;) the others are in a perfect fade to black.

is the only way in order to good rendering the image shown.
[Galaxy Note GT-N7000 General] D00ky:
nigi73 I've seen your post on the latest SpeedMod kernel topic. Have you by any chance tried it? If so, any improvement about black clipping?
[Galaxy Note GT-N7000 General] Rivan_92:
Guys, when you open the gamma test image look closely on the numbers 1-2-3 .. Do it many times to notice how when you open the picture it shows it kinda perfectly and then clipping or whatever starts.. WHY IS THIS HAPPENING?? HELP US SOMEONE!!! HELP USSSSSSS!!
[Galaxy Note GT-N7000 General] rishab_s:
It's just our note doesn't have smooth shades of grey , you will have to wait until some dev implements the fix , its just we dont have any kernel dev who can cook a kernel for our beloved notes.....
[Galaxy Note GT-N7000 General] straycat:
And why not Samsung??

It is Samsung who get my money, not any apreciate dev here or there. It is Samsung who take my money and give me this crap back. I'm not only thinking in black clipping but oficial firmware boot loop, emmc superbrick, etc, etc, etc.

We have plenty of devs here who knows more than Samsung itself. Here, there is a post to say what will be your next phone after the NOTE, I don't know what will be my next phone, I just know it won't be a Samsung. NOTE has been my first and only Samsung crap.

[Galaxy Note GT-N7000 General] nigi73:
Sorry for being late. No, I didn't. I am on Alliance ROM and it means kernel with TWRP recovery.

You are 100% right.

There is just one problem: nowadays every big company seems to have a lot of quality problems and no one seems to be good in admitting it, apologising and delivering fixes. All they care is sell sell sell...

I used to prefer HTC for good build quality, but they have bad record recently as well.
[Galaxy Note GT-N7000 General] sibere:
If set properly, I would not say so. The black ( level 0 ) is still a deep black. Of course if you do silly things and go stupid with the settings, you get crazy results. This app requires a fine tuning of the contrast ( only ! ) to get good redults.
[Galaxy Note GT-N7000 General] edgarson:
and you have perfect black on 0 and very light gray on 1,awesome solution. Go away, because you are wasting peoples time.
[Galaxy Note GT-N7000 General] Octhellio:
1-6 are all different shades. If you can't see them on your computer screen then it isn't calibrated well at all. You can barely see 1-5 but you should still be able to see them (up close), especially in dark environments.
[Galaxy Note GT-N7000 General] Formhault:
Please explain exactly what you did & set up to have this awesome result.

Hello,

Here is an official statement regarding this issue:

The display tuning to satisfy a variety consumers, is a trade off for an improved low light grid (in other words, noise).

The display will be enhanced starting from the next model.

Regards,

Samsung Developers

So, It's now confirmed that there will be NO fix/ patch for Us using the "previous model" because they said "NEXT".. i guess have to live with it..
[Galaxy Note GT-N7000 General] nigi73:
Why I am not surprised?

Buy new model... :laugh:
[Galaxy Note GT-N7000 General] marcoz14:
Same problem

Same problem here (from italy, sorry for my bad english)

My note have black clipping, i'm furous with samsung.

Samsung say NEXT model ??? NEXT modelll ???????

I had pay a lot of money my fyucking NOTE n7000 that praise one of the biggest screen!!

For Samsung i had to buy another NOTE 2 ????

PROOOOOOOOTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT

For me samsung must go to the fish market at work where you can take a scam for few money not fot 400 EURO !!!

**** YOU SAMSUNG !
[Galaxy Note GT-N7000 General] the_chemistry:
Yeah. No More Hope from Samsung. It ends today. I'm guessing that Samsung proportions the need for a fix (for previous user) to concentrating a fix for upcoming buyers,..and of course, they decided profit goes first.. After all, we are only just some few users who detects the defects while majority already traded in, never bothered or considered normal damage of usage.

This gives samsung big advantage in discarding fix for 'few complaints'.. if only this issue is addressed in large scale... things might be slightly different. Plus it's a 2 yr old device considering google android development is very fast.. just my 2c ;)
[Galaxy Note GT-N7000 General] sibere:
Who said awesome? I said good. It's far from being perfect but at least my screen is not clipping at 4 but at 1. We will never get a fix from samsung and at the moment I don't see any efficient and easy fix for ICS and JB.

Even supercurio stopped working a long time ago on this issue.

Back on topic, I adjusted the contrast parameter one notch at a time until the notification bar turned gray ( done in a dark room ). Then I pulled back to previous level where it was still black.

I know it is not perfect and not the result we're all hoping for. Normally the last levels should be almot unvisible like on a LCD screen. This has been discussed extensively on SC thread. Samusung f*ck up big time with the gamma settings on the Note 1.

If a Dev comes up with a perfect solution, I'll immediately drop this app for it.
[Galaxy Note GT-N7000 General] Formhault:
I did that and yeah, no more clipping at 1 - I can see even 1. But... black clipping does seem to still be present in real life situations... like in dark areas in games and photos or such. Anyway, it's better now.

Sent from my Galaxy Note held captive in Chasmodo's Asylum
[Galaxy Note GT-N7000 General] sibere:
Yes, there is still visible clipping since the last grey levels are way too bight. The transition from 1 to 0 is brutal. The app only gives the possibility to see them, not to lower their levels unfortunately.
[Galaxy Note GT-N7000 General] borich:
as i promised i took my note to the samsung's service center...

Screen replaced, (in 20 minute and this is good) but...black clipping is still here.

Too bad.
[Galaxy Note GT-N7000 General] Rivan_92:
Maybe if we made like I have seen before, a bounty thread (or whatever) people post how much they are willing to donate which the dev that fixes the black clipping will collect?..

But, seriously, I don´t understand this, do we really have no pro kernel dev for our n7000 or what?.. AnderiLux posted a possible fix, yet it seems that no one is even looking into that..
[Galaxy Note GT-N7000 General] D00ky:
On the opposite it is good to know that if you scratch your screen :)

The only thing that keeps from going to service is that I am on custom rom. One day till april 2014, when my warranty expires, I will definitely replace my screen. Event if it doesn't reduce black clipping at least I will have a new screen for the second anniversary of having Note :laugh:

---------- Post added at 08:41 PM ---------- Previous post was at 08:29 PM ----------

I am willing to donate. But as always there is "butt":

-But how much would people donate? I am afraid we are in minority on this problem.

-But is there any dev that is willing to make this kernel?

-But is there going to be kernel for stock or/and for AOSP roms? In my case I would really like to see a kernel for AOSP roms as I don't like stock.

I am sure that there is few more "butts" about this problem :)
[Galaxy Note GT-N7000 General] borich:
the best thing could be an app that writes and changes mdnie value on the go. Andreilux find the way, now a dev should implement it as an app.

this imho
[Galaxy Note GT-N7000 General] borich:
or implements stweaks...
[Galaxy Note GT-N7000 General] nigi73:
App would be OK. I would happily pay for it or buy donate version if it would be free and working.

But I lost hope and I do not care that much about clipping now.
[Galaxy Note GT-N7000 General] Rivan_92:
Lol, I´ve given up.. F*** this ****. I´ve learned my lesson..
[Galaxy Note GT-N7000 General] whydoes:
i would donate. not only for me, but for everyone using gtn7000.

even balck clipping is not bugging me too much.
[Galaxy Note GT-N7000 General] D00ky:
Sorry to leave you guys, but I've sold my GNote. Hope you get some sort of solution to black clipping. :fingers-crossed:
[Galaxy Note GT-N7000 General] kanwal.diku:
hey guys I have both the note and s3.. and s3 had the same issue as note..I woukd say it was rather worse on mine.... in the black gamma .png test the last no. displayed on s3 was 8... I was really pissed.. then I rooted and tried siyah kernel and perseus and bam the problem is gone and theres no black crush or clipping.. so definately theres some calibration issue only... now I was searching for same type of solution for note and came across a fairly recently relesaed kernel... I will post the link soon. the pro lem is its only for aosp and aokp... so I cant try.. if someone can try it will be really helpful

I have no time at the moment to try this patch on a touchwizz version of samsung kernel sources. I don't even know if it would work or even build with this bit of code added. But that could give directions for another kernel guru :)
[Galaxy Note GT-N7000 General] Rivan_92:

DH kernel doesn't fix the black crush problem, read the thread mate....
[Galaxy Note GT-N7000 General] sibere:
Really?

I honestly haven't got enough time to read the entire thread but I though the statement "Mdnie improvements. More sharpness. Black crush fix." in DH kernel's OP was true.
[Galaxy Note GT-N7000 General] Formhault:
What Neo did there... well, he just took patches from the kernels for the S3, which has a different mDNIe / display controller. AndreiLux said that himself.

So... that code does NOTHING for our Notes. AndreiLux told kernel devs what they need to do in order to fix / try to fix the black crush... THEY DID NOTING ! ! ! ! ! ! ! So... Take it to their kernel threads ;)
[Galaxy Note GT-N7000 General] :
tried dh kernel, its still there, but seems less.
[Galaxy Note GT-N7000 General] Rivan_92:
I dont get why the guy who made Speedmod cant make another version or a new one with the fix.. He said its fine as it is now but ITS NOT!!

Are there no other site where there may be kernel devs for our Note?..
[Galaxy Note GT-N7000 General] Formhault:
I feel ya mate :(

We may have a potential fix from AndreiLux, but no kernel dev wants to implement it?! :mad:

There is RootzWiki... but I doubt you'll find anyone there.
[Galaxy Note GT-N7000 General] sibere:
Got a bit of time to get Samsung ICS kernel sources, configure the toolchain (4.4.3 recommended by Samsung in their README) and build a stock kernel (except MMC_CAP_ERASE disabled of course)

I have the zImage file. Now when I've got a bit of time, I'll try to flash and boot from this kernel. If it's working, then I'll try to rebuild it but with the suggested solution from AndrediLux.

Tell me if I'm wrong but the one I found is this one
[Galaxy Note GT-N7000 General] Formhault:
Yeah. That's the solution.

You either remove those registers... Either you play with the values that lie at those addresses. I dunno.

Didn't notice your status is "Recognized Developer". It should be written in a more obvious form of text... *sigh*
[Galaxy Note GT-N7000 General] sibere:
If everything is fine and the kernel is booting, I'll delete all the instances of the registers found in sources and see what happens. I will for sure *not* have time to play with the values and rebuild/flash the kernel many times.

I still don't know why the kernel devs didn't try it yet.
[Galaxy Note GT-N7000 General] Formhault:
That makes (at least) two of us.

Keep us posted :good:
[Galaxy Note GT-N7000 General] borich:
i sold my note but...at least 3 of us
[Galaxy Note GT-N7000 General] sibere:
Quick update.

Got my build of stock ICS kernel booting on my phone. Next step is to nuke the gamma settings as per AndreiLux recommendations.

I found out that just this bit of the code

0x00D5, 0x0001, /*GAMMA end */

is interesting. changing 0x0001 to 0x0000 seems to be the way to deactivate the GAMMA tables.

So I have tried quite a few things like removing Gamma tables, playing with some values in some other files too but I see no changes at the moment :( I still have the f**king clipping/black crush!

Update:

No change so far on black crush BUT I have tuned the hue and the very light green tint is gone on my note :D The white/greys look much better!
[Galaxy Note GT-N7000 General] XxPixX:
Hi, I would like to thank you greatly for attempting to fix the black crush issue. I was just wondering, have you made any progress? is there still hope?
[Galaxy Note GT-N7000 General] Rivan_92:
Im guessing not, cause if he would have then he would have posted it here within the minute he noticed black clipping was gone.. Or he could be trying to sell the fix to Samsung..

Just ain't got much time to spend on this.

If I have any progress I will obviously report here !

Speed mod latest kernel is definately an improvement.. onthe gamma test image No.3 is easily readable and just no. 2 mins ago I saw 2 in a flicker of screen.don't know what it was though.but no. 3 Can definately be seen.. I also tested some videos and I can say although one can see minor black clipping but its definately watchable.. and a big improvement... you guys can try and post

So far nothing regarding the gamma curve :( It requires a lot of time to try one setting, build a new kernel and analyze the results.

But so far, removing all gamma settings in the kernel didn't do any good at solving the issue.
[Galaxy Note GT-N7000 General] Indian Devil:
Sorry for bumping this topic but I am having similar issues as well and I took it to service center and they told it might be issue with the LCD (Display) and told me to come back tomorrow and they will change and check.

Now I am not sure that it's due to Display else most of the users have had their problem resolved and am a bit worried for unnecessary experiment with the phone.

But I checked 2 new N-7000 today and both have fabulous display no problem what so ever, I even did a Gamma Image test and in both I can read upto 2, so I am not too sure... What say should I try changing the display and see if it helps or just live with it?

Thanks for advice
[Galaxy Note GT-N7000 General] Formhault:
Tell me, does 21 look brighter than 20, and 20 brighter than 19, and 19 brighter than 18 and so on?
[Galaxy Note GT-N7000 General] Indian Devil:
21 to 11 they all look the same and 10 to 4 they all look same. Also 4 is underlined, i.e. there's a line below 4.

I will try to post a Picture soon, as soon as I get my hands on my brothers cell to tell exactly what it looks like.
[Galaxy Note GT-N7000 General] Formhault:
That, my friend, is black clipping. All levels should have different colors in that box. You shouldn't be able to see below 6 without looking very closely (6-1 = veeeeeeeeeeeeeery dark, but not BLACK).

It doesn't matter if 21->1 are gray. 0 is the closest to black, so when you display an image with very dark gray portions in it, the screen won't be able to reproduce that very dark gray but black, instead : so you get black clipping.

Take this and this picture for example. How do they look on the phone? Like total crap, right?
[Galaxy Note GT-N7000 General] Indian Devil:
Yeah so I thought and probably know.

My question was would changing display/lcd help with this? Or this a hardware issue?

As I told I checked 2 new set of N-7000 and both didn't have any issues, the display was perfect and they successfully passed the Gamma Image test as well. If this issue is due to software then it should have been present in the new sets as well, don't you think so?
[Galaxy Note GT-N7000 General] Formhault:
It can be solved through software (NX Kernel), to some extent - still, no 100% fix.

So... Let me get this straight, AGAIN. Those two Notes displayed 21 different tones of colors in the gamma test image? Or... like you previously said... 10-4 was the same etc...?

Also, re-check my previous post. I inserted two images you might wanna have a look at there.
[Galaxy Note GT-N7000 General] Indian Devil:
Ok thanks will check that, hopefully it won't increase the flash counter

Yes they displayed 21 different tones of colors. Getting dark gradually from 21 to 2 (if I remember correctly and then it's very dark to read need to strain the eyes)

They look **** :(
[Galaxy Note GT-N7000 General] Formhault:
It won't. Not if you flash with ClockworkMod Recovery - if you have it already. You don't? You're on stock? Holy sh*t, how can you take it? :eek:

I don't know how to root & get CWM anymore :) . Don't ask me that. Search the threads :good:

---------- Post added at 12:48 PM ---------- Previous post was at 12:45 PM ----------

That's how it should be like. Gradually dark from 21 to as low as possible.

2 and 1 should be extremely dark, very hard to see.

Anyway, the Notes affected by black clipping display pitch black from 4 and below, so... seeing down to 2 means those Notes were not having the same problem.

On your phone... Or on those two Notes you said had gorgeous displays?
[Galaxy Note GT-N7000 General] Indian Devil:
On my phone :(

I am on Philz kernel, think that's CWM alright.
[Galaxy Note GT-N7000 General] neier24:
Letting the worries aside... this is actually good news.

This could be a lot worse. A bug that doesn't turn off the pixels, leaving the screen partially on when on black.
[Galaxy Note GT-N7000 General] Formhault:
How is this good news? This only means we are being DITCHED by their own dev branch.

[MENTION]@neobuddy89[/MENTION] proved that it can be partially solved through software. Samsung didn't even try!

Also... What bug that doesn't turn off the pixels? :rolleyes:

Sent from hyperspace
[Galaxy Note GT-N7000 General] neier24:
Could have been a software issue. Clearly is the way these screens are build from factory. Any software tweak won't change that.
[Galaxy Note GT-N7000 General] Formhault:
Screen dimmer increases gamma, hence making blacks actual gray :)

Sent from hyperspace
[Galaxy Note GT-N7000 General] neier24:
Its obvious. How would tweaking from software work if anything but black is changeable. You can increase/lower red, blue, green... that's all.
[Galaxy Note GT-N7000 General] Formhault:
That's what we need to alter - anything BESIDES black. Make the gamma test image look more like this (even that isn't best). See, colors going gradually darker, not in jumps...

Think of it like the brightness slider. It has 100 steps, right? 101, if you include the 0% step.

Well... you wouldn't like it if it only had 3 steps, right? :p

More elaborated info, the way I see it, here.
[Galaxy Note GT-N7000 General] neier24:
Its good man. Don't worry. Look on the link, its reproduced quite like an elite screen.

The dark clipping isnt a problem in bright sun. What matter the most for me is that the white doesn't bleed on black, which isn't. Samsung is a genius with these screens. I'd like though a full hd screen like the s4 has.
[Galaxy Note GT-N7000 General] Formhault:
Nope. It's not elite. HTC One / Sony Xperia Z or any other IPS / TFT screen would most accurately display the gamma test image.

It can be spotted in bright sun, too. Your untrained eyes will just be too busy trying to detect what is actually on the screen :p .

You think so?

They're genius because AMOLED looks so crisp. They're not genius when they make it oversaturate colors (please, no Disney!).

The S4 doesn't have a perfect screen. It's better that previous versions, but still not LCD-good when it comes to color reproduction.

PS : There's a Samsung TV with black clipping, too :silly: .
[Galaxy Note GT-N7000 General] qazibasit:
This clipping is only in low brightness when using night mode app. I looked all the way to notice it generally. But on stock rom there is no such clipping.
[Galaxy Note GT-N7000 General] borich:
ok, it slightly improves, but not solve the problem.
[Galaxy Note GT-N7000 General] Formhault:
I have multiple apps for viewing images / whatever. The stock Gallery app (the one that comes with the stock Android 4.0.4 ROM) and QuickPic. The gamma test image looks awful : 0-1-2-3 = black.

I also installed Camera JB+ and tried that one as well. Only 0 is black, 1, 2 and 3 are visible, no matter the environmental light!

It really is a software issue. It only has to be implemented at the very low-level (kernel, that is, and mDNIe, I guess).

That shouldn't be hard to do. In fact, it should be very easy.

I believe they implemented a lock at the low-level so that the gamma can't be tuned.
[Galaxy Note GT-N7000 General] borich:
i saw your post on samsung developers...much better than mine;)

ps: same story with jb camera for me
[Galaxy Note GT-N7000 General] Formhault:
