From 1:11 to 1:12 there is a sudden and noticeable drop of black levels on the background is this how its supposed to be ? I kinda need to know how this video is really intended to be presented.
[Galaxy Note GT-N7000 General] Hirudin:
Thanks supercurio! Once I get my Note rooted I'll be installing your app and sending you some bucks!

To anyone looking for a way to donate to supercurio: there is a "Donate to me" link over by his avatar on the left.
[Galaxy Note GT-N7000 General] npras42:
Thanks for doing that EarlZ, I havent got round to it. Mind sharing what the figures were for the background and the aforementioned black circle? If I understand you correctly there's a few possibilities here as I can tell:

1) There is some sort of post-processing occuring that is changing the way the backgound is being rendered from one moment to another. Kinda like a dynamic contrast.

2) Your eyes are re-adjusting when something even darker appears on screen and so it makes you think the background is getting brighter when it isnt.

Either way, I think if the S2 is not rendering a difference between the circle and the background I dont think that can be correct.

EDIT: You just ninja-edited me, EarlZ! :p
[Galaxy Note GT-N7000 General] EarlZ:
I realized what I psoted was a bit longer and really non essential and I just wanted to know if you guys see a sudden drop in black level at the said scene in native mode.

[Galaxy Note GT-N7000 General] supercurio:
Yes it should be closer to this kind of gradation.

With 4 3 2 1 very hard to distinct except in very dark environmental conditions.
[Galaxy Note GT-N7000 General] sibere:
except the big step btwn 10 and 11, I wish my screen look like the left one ;)
[Galaxy Note GT-N7000 General] supercurio:
Oh, reading your message reminds me to strongly recommend to disable CABC (named as automatic display power save - something like that :P)

While it can indeed help saving power in some conditions it doesn't help at all with calibration or analysis;)
[Galaxy Note GT-N7000 General] BerreZ:
You're a genius

The application is showing already much better results with the black levels in the video . It probably needs some fine tuning , but you're on the right track.

I've send you a donation , thanks again.

After apply @Voodoo Screen Tuning R&D@ my look average between left and right foto

But my brothers galaxy note look like left foto but little darker w\o apply @Voodoo Screen Tuning R&D@ just after samsung service screen replacement
[Galaxy Note GT-N7000 General] supercurio:
Thanks a lot for the donation BerreZ. It was unexpected and is deeply appreciated!
[Galaxy Note GT-N7000 General] brockyneo:
Really sorry for asking maybe a stupid question I've installed via market but how do i use the app lol
[Galaxy Note GT-N7000 General] supercurio:
Push Native.

Samsung restore Samsung settings (doesn't restore yet the full default settings until reboot in every situation)
[Galaxy Note GT-N7000 General] Ziplomatic:
Supercurio is just going and doing right!!!

BIG difference totally!!!

With brightness level 4-5 its totally fine! Just some adjustments and tuning for the lowest brightness level! :D

P.S: Screen filters do enhance the problem in the first place.
[Galaxy Note GT-N7000 General] TML1504:
videos definitely look better (btw.: i like moderat since years, "new error" is a very nice song too :D),

but low light pictures show now a very annoying and grainy "dithering overlay" in before black areas. right, i understand that the "before black" was no real black, but in my aesthetics i prefer the "samsung mode" for pics, at least for the moment!

also, to get rid of the dithering in pictures a restart is required, i guess this is one of the situations supercurio meant with "...not in every situation"!

apart from that a big thx to supercurio!!

i also bought the louder app days ago, but not for donation purpose, i actually use it every day and cant live without it anymore ;)

Hi Supercurio.. Under setting there is a "screen mode" option..does this has relation with the gamma? Its seems when i selected dynamic option the screen become more and more vivid :) Guess it will consume more power compare to standard option.

[Galaxy Note GT-N7000 General] Lazy Rich:
Am I the only one that is seeing no differences? Is it kernel related? I'm using FM kernel 1.5 and I really don't see any difference, even at max. brightness... :confused:

Me too. I am with Abyss 2.8 Kernel and really I can't see the difference, after pushing native...

PLS help!
[Galaxy Note GT-N7000 General] QuadLight:
Use the default profile in the display settings. Is not dynamic and not a "movie"

For check - open "gammatest.png" in quickpic (take from androind market)

Before apply "native" only visible 4 - 5 - 6 and etc

After apply - 2-3-4 - This shows that previously were not visible gradations are now displayed

This is not a "WOW" effect but in black area in movies - less black blocks but not perfect any way

But this is not the solution. This is part of the way to solving the problem

The first step. The second step is to configure the overall gamma. The author is already working on new profiles.

Ideal - as it should be, I showed previously - http://imageshack.us/photo/my-images/818/25194847.jpg/ (galaxy note on left)
[Galaxy Note GT-N7000 General] EarlZ:
Had my screen replaced today and Im noticing even more black clipping or maybe Im just imagining things can anyone check the attached image and see if they find some black clipping on the "ears" part of Optimus Prime.

If we get that to work on the Gnote then it could probably remove about 95% of the black clipping on the Gnote
[Galaxy Note GT-N7000 General] asci:
Where to find the png for testing? I wasn't able to find it on the market...
[Galaxy Note GT-N7000 General] QuadLight:
one of my two devices the picture looks fine. No black blocks.

But on a computer screen all the image darker. The problem in GNOTE with high brightness (gamma)

As soon as supercurio the release profiles, I think everything will be better (more darker) :D

[Galaxy Note GT-N7000 General] EarlZ:
Let me clarify this one of your Gnote's shows perfect blacks and the other one shows clipping ?

EDIT:

Also one more thing can you check this image on your note ( w/o any visual tweaks )

I initially thought this image was all black then I saw the grey grid lines on this new screen, with my previous screen it was all black and no color banding from the chest and eyes now the new screen shows more detail but also introduces banding on the chest and eyes.

Man the color calibration of these screens are pretty random!
[Galaxy Note GT-N7000 General] QuadLight:
Yes. :)

Its not global problem - Wrong callibration of gamma level on factory by samsung thats all !

i dont see black clipping on "4" or over pictures or movies because the overall level of gamma is lower .. more correct. that's all

---------- Post added at 06:49 PM ---------- Previous post was at 06:43 PM ----------

You a complete right. confirm on one of my note iron man body w\o grid but in very very dark room i can see come grid line (near visible level)
[Galaxy Note GT-N7000 General] EarlZ:
On my older screen its not visible but on this new one its easily seen.
[Galaxy Note GT-N7000 General] Inuit:
Hi EarlZ,

Same problem with your pictures. Otherwise my screen is perfect. But if supercurio can't find a solution for this i'll send back my phone to the seller. I really hate Samsung for this. If i buy a phone with such a big screen i want to watch movies and pictures.
[Galaxy Note GT-N7000 General] EarlZ:
He might not be able to make his fix work perfectly on all the Note's out there due to the massive difference in every screen but for sure 7 days wont be enough so you need to give him more time.

I can understand your frustration about this as I feel the same. I dont hate samsung but this will probably be my last device from them unless SAMOLED tech matures enough or I find a perfect screen right out the bat from purchase.

My Samsung wave had 0 screen issues, my galaxy s1 and so did my friends galaxy S1's never had image quality issues.. this all started with the S2 on our experience.

Lets not turn this into a rant thread, feel free to discuss it on the screen issues thread.
[Galaxy Note GT-N7000 General] asci:
It seems perfect to me...I have the supercurio profile on.

---------- Post added at 08:42 PM ---------- Previous post was at 08:41 PM ----------

I can see the grid on the chest, but I have to zoom in a little. I am with supercurio profile on.
[Galaxy Note GT-N7000 General] Braxos:
I dled both pictures both seem same on low and high brightness. Using movie color management normal but for this changed to standard. On purepureblack.png i can see till 4 with movie and standard with dynamic it goes to 3 but something feels not right it isn't smooth from bright to dark it changes too abrupt.

Not rooted not on custom Rom. Those are last resort solutions. And if isn't coming from me i am about suspicious. As long it has something to do with personal things and can't control it what it does and when. Better to have Samsung controlling what i do and not some stranger.

Yeah yeah they are out there.
[Galaxy Note GT-N7000 General] EarlZ:
By perfect you mean you no longer have any black clipping on the entire test video if thats the case then good for you.

I was posting a comparison from my old screen to the new one with his fix disabled, if you want to report your findings disable his profile, reboot the phone and check the image and view it in landscape.

Brightness levels barely matters on the black clipping just make sure you are in a environment where there are no reflections on the screen or go into a dark room to verify if there is no black clipping.
[Galaxy Note GT-N7000 General] Braxos:
I was on a dark room no difference at all. My phone has black problems on video xda app has a cap log in screen same as skype and black screenlocks have stripes. Grey photos few just noticeable stripes. Btw body photo has no grid on shoulders and on head. I see the grid easy without any black problems the ear of optimus is fine. But i think not sure i saved the photos not dled them via xda app this may have altered the image quality.
[Galaxy Note GT-N7000 General] QuadLight:
it's problem #1

this is problem #2 - its totaly software in gingerbread.

posible problem #3 - totaly hardware - can not be solved - only display replacement in samsung service / EarlZ had such problem earlier.
[Galaxy Note GT-N7000 General] Braxos:
It isn't such a problem to send it in for some npobs to open it and replace something that isn't noticeable except on few pics with some circumstances. Better to have a untouched "problematic" phone then to have a opened "fixed" phone. All of the phones problem can not be taken in mind if you avoid the situation that can replicate the issue. Except the black on the videos that are making me crazy all others are on such degree acceptable.

As i have commented before if you want a flawless phone go buy a Nokia 6230. If you want a flawless smartphone go buy a time machine.
[Galaxy Note GT-N7000 General] noteworthy:
I think the black rendering in movies is the biggest fault of the note unless ICS fixes it or supercurio does.All other problems can be resolved.

There is no doubt some movies are not watchable because of the pixelation and blotches.It is not a huge issue for me because I don't watch movies on my phone.I prefer to watch them on my plasma.Most videos play fine.

Sharp,HD videos are more important to me than perfect blacks when I am using the note on the train.Remember it's a phone not a dedicated tv for watching movies.
[Galaxy Note GT-N7000 General] AnandA777:
Installed Screen Tuner. Gamma is more accurate than in Native mode, and the banding that happens in a number of apps is FAR less noticeable.

Someone had mentioned the Calculator app. The banding is much better in that app, but I noticed another difference, too. If you look at, for example, the edges of the almost vertical part of the '5' in Samsung mode, you can see jaggies; the edges are much smoother in Native mode.

Made a small donation. I appreciate any work done to improve the Note, and I respect people who want to do things right. Please keep up the good work!
[Galaxy Note GT-N7000 General] EarlZ:
The GNexus is on ICS and it has the same problem.

I was watching real steal last night on my phone and the video is probably like 85% blocky all the way w/o supercurio's fix.

You may have that kind of expectations but others like me dont, since the older generation SAMOLED phones render it perfectly.

And some movies depsite how sharp are not watchable with the clipping, one example is red steal.

Also my Transformers 3 now clips on this new screen.. such a disappointment 1 problem fixed but another problem takes its place.

Im just glad though at this early stage supercurio's fix makes alleviates about 95% of the black issues.
[Galaxy Note GT-N7000 General] Inuit:
Hi EarlZ,

"Im just glad though at this early stage supercurio's fix makes alleviates about 95% of the black issues."

You mean, that with supercurios fix videos with a lot of blacks are now watchable for you?

For me, it makes nearly no difference at all. Blacks are still blocky.

Only "solution" for me is to use the app Screen Adjuster and set contrast to 50.

Blacks are no more blacks but the black blocks ar nearly invisible. Not the best solution but better then nothing....

Grretings
[Galaxy Note GT-N7000 General] EarlZ:
Yes it makes it more watchable, you need to be using the normal screen mode, it wont work in dynamic or movie mode.
[Galaxy Note GT-N7000 General] Ziplomatic:
+1!!!

Definitely with this early stage fix Supercurio has provided us, My GNote breathes black shades much much much better than it could before!

The blockiness has been significantly reduced by 80%!!!

A BIG THUMBS up to Supercurio for considering & looking into this matter where few days back few of us just discussed it with little or no hope of improvement!

A big Thank You!!! :)
[Galaxy Note GT-N7000 General] EarlZ:
Exactly, When I was watching real steel last night the fix really made a huge difference w/o the fix almost anything in the movie that is not shot in daylight showed massive blockiness, the fix is far from perfect but it does a good job. I also noticed it adds some sort of a greyish tone the darker scenes but this is a WIP. I just hope that one day we get results close to the Galaxy S1/S2.

EDIT:

This is a clip from real steel notice the difference between samsung mode and native, it makes an entirely unwatchable clip to something what samsung should have initially shipped.

[Galaxy Note GT-N7000 General] Inuit:
Because i saw no difference in Samsung/Native mode my last idea was to do a hardresetet and now i have to say "FANTASTIC WORK SUPERCURIO". It´s a difference like day and night.

Now movies are watchable. Incredible work in such a short time.

Thank you very much.
[Galaxy Note GT-N7000 General] noteworthy:
I can confirm Screen Adjuster set at 50 contrast alleviates almost all blotchiness.Blacks are more grey now but at least dark scenes are watchable.

I think this goes to show it's a picture tuning problem and not the display hardware.Samsung obviously has tuned it for eye popping color saturation at the expense of poor black rendering.

For me,there are no more issues with the note.Can it be better?Sure,but overall it's the best phone right now.
[Galaxy Note GT-N7000 General] EarlZ:
Supercurio already replied about that.

Whats annoying me more is that some screens have far lesser black clipping.
[Galaxy Note GT-N7000 General] supercurio:
Okay guys!

After hacking Galaxy Note kernel source and writing an additional dedicated driver kernel module, I managed to recreate a color profile from scratch solving 100% of the color rendering issues described all over the forum.

Its not what I would consider perfect yet (and measurement confirm) but its already very good to my standards.

I introduced a slight green cast in some conditions (0% brightness) that needs to be solved.

Also I just spent a few hours discussing with Samsung about it today and the issue might be escalated to the A/V team.

So what's next.

My goal is to package it as an app to mask the underlying implementation complexity and make it more than easy to use.

I intend to sell it, a bit like Voodoo LOUDER: cheap.

The app will require root and will provide powerful features:

- Simple gamma-like control to customize the rendering already based on my calibrated profile.

- Complete color profile editor with the ability to save and share presets.

Warning: its very hard to create an accurate profile, but I'm sure a few will have fun creating custom looks.

The first component (which is really a mDNIe fix not really a creation) released already in Voodoo Screen tuning, addressing mostly black crunching will stay free of course.

I don't know yet how the calibrated profile will translate on each screen but I have good hope thanks to massive improvements in Samsung base Super AMOLED HD driver compared to previous generations.

This time the "factory calibration" part looks okay. "Only" the color calibration profile + mDNIe settings were wrong.

[Galaxy Note GT-N7000 General] QuadLight:
Can't wait

Just 1 Question !!!!!!!!!! when ???????
[Galaxy Note GT-N7000 General] evil-doer:
so this next app wont just shift the banding levels around, it will get rid of them?
[Galaxy Note GT-N7000 General] noteworthy:
Well,it looks like a fixable issue anyway as supercurio has hinted.You might get deep blacks as well as HD without the artifacts.

Even without the deep blacks like the s2,i was watching the dark knight side by side with the note and I still prefer the bigger screen and sharper definition.It's just not enjoyable watching a video on a small,low definition display regardless of color.

Next step will be 1080p for the note.My next phone in 2 years.LOL
[Galaxy Note GT-N7000 General] Jeshter2000:

As a matter of fact one project I have to complete before releasing this Galaxy Note work is that:

Alternative and independent in-app billing system for Android apps for developers
[Galaxy Note GT-N7000 General] EarlZ:
I now have tears of joy after reading this! Hopefully samsung will listen to you an also implement a fix in their side.
[Galaxy Note GT-N7000 General] supercurio:
You mean 1080p screen? lol :)

If its about playing 1080p content: works beautifully already of course ;)
[Galaxy Note GT-N7000 General] noteworthy:
I have noticed that the blotchiness is worse in some HD youtube videos.Some are so bad I can see it on my notebook display.It's just that on the Note it is exaggerated.Using the Screen Adjuster app smooths it out but at expense of lighter blacks.An acceptable trade off.

I hope Samsung or supercurio comes up with a better fix.

---------- Post added at 12:16 AM ---------- Previous post was at 12:13 AM ----------

Yeah,I mean 1920x1080 display.That would be absolute eye candy.

Even now i just look at the display more than I use the phone.LOL
[Galaxy Note GT-N7000 General] QuadLight:
I don't have any problem with the purchase "Voodoo louder" in android market

have we a chance to see the application in the android market soon ???
[Galaxy Note GT-N7000 General] evil-doer:
um, no it wouldnt. its already at the point where pixels cant be seen, any more resolution on a device of this size would be wasted. it cant look any better by adding pixels.
[Galaxy Note GT-N7000 General] noteworthy:
You're probably right but I suspect in two years they will up the resolution anyway to retina standard.Maybe 1920x1080 is overkill on a 5.3 in display.
[Galaxy Note GT-N7000 General] supercurio:
I guess would personally prefer a the same screen, non-pentile 1280x800 instead of pentile 1920x.

However (sorry for the teasing) you'll see that with the improved color profile, Galaxy Note display exhibit a better text perceived sharpness, thanks to its near-black behavior.

And this with sharpness filter disabled.
[Galaxy Note GT-N7000 General] EarlZ:
Im getting more and more excited about this new color profile!

The new screen I have seems to have a higher gamma level on blacks/greys its so high that I now see a lot more of this clipping where they were none it also makes the colors a bit washed out or under saturated and even makes Dynamic color mode usable.
[Galaxy Note GT-N7000 General] honf:
Oh, I am interested if the black banding issues will be fixed :D
[Galaxy Note GT-N7000 General] supercurio:
No, banding issue will be fixed only with ICS and 32bit mode everywhere.
[Galaxy Note GT-N7000 General] honf:
Ah, figured it was so.

I have a bad feeling the hardware decoder for movies doesn't support 24/32bit mode.
[Galaxy Note GT-N7000 General] EarlZ:
I think what supercurio ment was just the regular color banding, for the black clipping I think he can fix it in movies and pictures.
[Galaxy Note GT-N7000 General] supercurio:
No room for feelings here: videos are hardware-decoded with high quality post-processing+scaling and displayed on 24 bit surfaces.
[Galaxy Note GT-N7000 General] Ziplomatic:
Noobie here!

So your fix which is soon to be available to us is what i.c.s would provide as a fix to the G.Note color profile issue??

Because some people say (I don't know with what back up) that i.c.s would not be providing any sort of fix to this issue :confused:
[Samsung Galaxy Nexus] nizaamh:
Hi Guys.Maybe newb question.

Got my GN while on holiday in Malaysia. In the settings/system I have developer options.Normal USB Debugging etc. but also Developer Device ID and some extra developer options. Is this normal or a developer device.

I cant compare with other GN devices because its not yet released in my country,South Africa.

Any thoughts appreciated.
