My GT-P7510 Google IO tab touch sensitivity is spot-on, but the other one (commercial GT-P7500) lacks a bit in terms of touch responsiveness so I think I see what you mean.

No developer messed with the digitizer settings yet?

By working for you, with them!

I have very regular contacts with people paying attention to the work hackers do at Samsung Mobile US and Korea.

For the record, I bought an ASUS Transformer first and I must admit I would not have dev'ed for the Tab 10.1 if they didn't sent me devices.

Win-Win, and If my plan is to sell advanced color controls, I take care sharing the most important features for free as you can see.
[Galaxy Tab 10.1 Android Development] supercurio:
Note:

In current version: only a reboot let you go back to the original Samsung screen settings.
[Galaxy Tab 10.1 Android Development] Vlad_z:
Welcome to tab's 10.1 world.

And by the way, not that I demand something, do you aware of voodoo sound problem when 10.1 is working through phones - volume control does not regulate much... there are only like 4-5 steps in volume range.
[Galaxy Tab 10.1 Android Development] supercurio:
As I repeat over and over, I only pushed some code on github like I always do in real-time, but its never been meant to be re-used in distributed kernels for end-users.

So no it's not broken, it's just not supposed to be available at all − yet.

Thanks for passing by the message.
[Galaxy Tab 10.1 Android Development] Vlad_z:
Fare enough... I just wish pershoot should not use voodoo sound patch then. I am on his kernel.
[Galaxy Tab 10.1 Android Development] SeanHacker:
dont use his kernel then bro.

@supercurio

glad to have you over here bro!
[Galaxy Tab 10.1 Android Development] nakedninja42:
Glad that Samsung was smart enough to send you a Tab!!
[Galaxy Tab 10.1 Android Development] FillTheVoid:
Welcome supercurio! This is very exciting indeed.
[Galaxy Tab 10.1 Android Development] wlighter:
Install and reboot. That's it right? No config or anything....?
[Galaxy Tab 10.1 Android Development] nandihno:
excellent last time i saw u was back when i had my IS9000 :D

welcome! :D

i applied your app and wow..the colors are more natural now..lots better! :D
[Galaxy Tab 10.1 Android Development] Zikor:
Finally a well known dev!! glad to see devs like supercurio aboard the gtab market.

Will test this out when i get home :]
[Galaxy Tab 10.1 Android Development] Tubes6al4v:
so how does this differ from the render effects in cyanogenmod?
[Galaxy Tab 10.1 Android Development] MarcAntonyy:
The GTab just keeps getting better! This deserves a BEWM!

Welcome aboard mate!!!
[Galaxy Tab 10.1 Android Development] wlighter:
LOL... perhaps I am doing it wrong, but I notice no significant differences what so ever :P
[Galaxy Tab 10.1 Android Development] hpblze:
note taking / sketching

YES! finally the right man for this

Please look into the digitizer accuracy for the Galaxy tab GT P7500

The note taking is bad on this plus slow movement of finget or stylus gives a wavy line on diagonals

do respond on this , a lot would benefit if the note taking worked reliably
[Galaxy Tab 10.1 Android Development] Deleted member 3976874:
so I installed your app, rebooted and opened it, I get the native white option and the 6500K white option, now what? the native white seems much better than 6500K white.

Am I missing anything?
[Galaxy Tab 10.1 Android Development] paua__:
Screen settings set back to standard, rebooted twice.

When i touch the overlay buttons, my tab freezes for 3-4 secs. No change in color :-( I've prolly done something wrong. Help?

I'm on latest "In Paris ROM" w/pershoots latest kernel....

Will screen tuning be implemented into voodoo control for our tabs like in the i9000 voodoo control app?

Sent from my nokia 3210
[Galaxy Tab 10.1 Android Development] Taskman:
Great work supercurio. Keep it up.
[Galaxy Tab 10.1 Android Development] kokjsch:
Is it availible in motorola xoom?

I think this app is awesome!

Your developments are incredible
[Galaxy Tab 10.1 Android Development] supercurio:
Thanks! Sorry to disappoint, this app's backend is using a very powerful image processing hardware present only in Samsung devices − aka mDNIe.

As usual, it's not just an app but the result of hacking and reverse-engineering ;)
[Galaxy Tab 10.1 Android Development] supercurio:
Reboot only if you want to go back to Samsung's default screen settings.

In current version, you can switch between Voodoo #1 profile and Voodoo 6500k #1 color profiles.
[Galaxy Tab 10.1 Android Development] supercurio:
Well, it just has nothing in common :)

This work here affects screen hardware directly.

Only this approach can provide an accurate and pleasing color rendition because it has also the ability to fix the overcooked Samsung image settings.

CM filters are implemented in OpenGL: eat some GPU bandwidth, which is not an issue with most phones but not welcome on Tegra2, kind of lacking already in this area (especially in portrait mode).
[Galaxy Tab 10.1 Android Development] supercurio:
Is your device rooted?
[Galaxy Tab 10.1 Android Development] supercurio:
Sorry I don't target custom ROMs/ kernels.

Maybe its because of bugs introduced by those mods.

Freeze: sounds like a broken superuser database, try to uninstall / re-install Superuser or fix its database manually

Nope it's a different project, Voodoo Control will eventually address sound stuff only. This app here is just temporary during the R&D phase and will be replaced by something else with better usability.

As you can see today's version is very early work, just to give you access to better profiles I'm working on.

The long term goal is to offer complete control over color rendering, including features like:

- color saturation

- dynamic contrast parameters

- gamma curve

- additional sharpness filter for blurry eyes :P

- color temperature adjustments

- noise reduction filters and video deblocking/de-ringing processing
[Galaxy Tab 10.1 Android Development] used2hvatreo:
Thanks for the hard work, pretty much been utilizing your stuff on all my phones, glad to see you are playing with the SGT10.1 too
[Galaxy Tab 10.1 Android Development] jaybizza:
Welcome Aboard SUPERCURIO!!!! It's always nice to see a Recognized Developer working to better our tabs... I LOVE your work and look forward to using this on my G-Tab... I do appreciate your HARD WORK and I'm sure I speak for the COMMUNITY as a WHOLE......"U DA MAN"!!!:D
[Galaxy Tab 10.1 Android Development] wlighter:
Thanks supercurio. I finally figured what was wrong with mine. The SU wasn't giving permission to the app. The native one looks much better then the 6500k imho. The 6500k looks warmer...
[Galaxy Tab 10.1 Android Development] hackeron:
Hi supercurio, Im currently running a voodoo color supported kernel. I quess this app and old voodoo color dont like each other?
[Galaxy Tab 10.1 Android Development] supercurio:
This is a Galaxy Tab 10.1 thread.
[Galaxy Tab 10.1 Android Development] mike2nl:
@supercurio:

very well done and welcome... for me the native mode is a lot better.

I hope... we will see more from you!

Thank you

BTW:

the screen test patterns are a fine tool to check things.
[Galaxy Tab 10.1 Android Development] supercurio:
Native mode, you mean Samsung original display settings?

Yes I wrote it in this purpose :) in order to build accurate screen profiles using a colorimeter.
[Galaxy Tab 10.1 Android Development] mike2nl:
I mean the Vodoo native white #1 NOT the warmer Vodoo 6500K white #1.

Because i use eye glases when i work with computer stuff.
[Galaxy Tab 10.1 Android Development] overhaze:
Probably not the best place place to ask but I know you have worked on the device supercurio, any plans to implement something similar on the Eee Pad Transformer? The screen on this thing is capable of much more than than the overly cool calibration Asus went with.
[Galaxy Tab 10.1 Android Development] soroush0313:
Hello supercurio

Could you please send me link od Voodoo for download please?

I can't access Market because Its not available in my country.

Please send me the link to apk :)
[Galaxy Tab 10.1 Android Development] fczeuner:
Welome to the Tab world Supercurio. I am super happy to see you developing for our tablet. I've been a fan of your work since my Epic 4g days. The only reason I bought the Samsung Tab 10.1 was because of Voodoo sound. Because Asus has locked down the bootloader of the newer B70 series and above Transformer tablets it was my only alternative for voodoo sound.
[Galaxy Tab 10.1 Android Development] Sagui:
Good to see you aboard! This digitizer issue is the one thing preventing me from using the tab for taking handwritten notes or reading my scientific journals and annotating them etc. without killing trees. I already have the stylus (the one with the see-through disc), now the tab just needs to keep up with my quick scribbling.

I would totally donate some beers if it speeds along the process ;)
[Galaxy Tab 10.1 Android Development] Itaintrite:
Isn't the Native mode just regular Samsung color profile?
[Galaxy Tab 10.1 Android Development] foethalove:
Great to see you in the Galaxy Tab forums Supercurio. I have been enjoying your Voodoo work for a while on my Nexus S, both DAC and color profiles.

Wanted to let you know I think the 6500K profile is fantastic. Love the warm feel and much easier on the eyes.

Can't wait to see the final project.

PS: I hope you can get your hands on a Galaxy Nexus when it arrives. I need Voodoo...
[Galaxy Tab 10.1 Android Development] yalkowni:
What about the asus transformer does this work on the transformer
[Galaxy Tab 10.1 Android Development] Entropy512:
Tried it, so far:

1) It forces portrait mode, even though "normal" orientation on a 10.1 is landscape.

2) The buttons for the two presets do not appear in the main app, only in overlay mode on the 10.1 - seems fine on SGS2 (I777) other than my eyes not being able to tell the difference between the I777 settings, have not had a chance to test on Infuse yet.

3) Not really an issue - but did Samsung REALLY set the color temp so high that it's over 6500K in native mode? I guess I should probably dust off my Pantone Huey and check...
[Galaxy Tab 10.1 Android Development] Jake-CT:
This is great. I would give the new color profile five minutes and then you won't want to go back. It looks overly warm at first compared to stock but once you adjust it is the better one.
[Galaxy Tab 10.1 Android Development] Skilover:
Voodoo#1 makes the screen incredibly sharp and clean looking; not to mention bright.
[Galaxy Tab 10.1 Android Development] mramirezusa:
Just quick note I just tested on my 8.9 galaxy tab and it work like a charm

Thanks
[Galaxy Tab 10.1 Android Development] Hawkeyed:
Awesome. Thank you so much for this. :)
[Galaxy Tab 10.1 Android Development] siggehandf:
A question that is a little of topic. But shut do Android tablets have that 1 second delay before they start scrolling? Alerts wondered why that is.
[Galaxy Tab 10.1 Android Development] mike2nl:
Yes it is... but yesterday in the night i have changed to the 6500K color, and i must say now after some sessions on my tab the 6500K looks better and my eyes can working faster, strange but very good.
[Galaxy Tab 10.1 Android Development] xManMythLegend:
Just wanna say thanks for dropping this on there , and for answering the question about voodoo sound as it was bothering me as well.

BTW Do you have any insight as to why there are never any native display controls ? Ive never seen a TV set without them but mobile devices never have them. ((some have pre sets but even thats extra rare)).
[Galaxy Tab 10.1 Android Development] giltwist:
Some of you have mentioned the screen is brighter with this active. Have you noticed significant changes in battery life?
[Galaxy Tab 10.1 Android Development] xManMythLegend:
Had same issue...Superuser set to auto accept fixed this.

Native seems alot better than 6500k maybe because I hate "warm" and what it does to whites.
[Galaxy Tab 10.1 Android Development] supercurio:
I agree ASUS Transformer screen can do much better.

Unfortunately I found nothing (hardware wise) giving the ability to change the color response.

Maybe Tegra2 hardware as some LUT somewhere, but it's documented nowhere.
[Galaxy Tab 10.1 Android Development] supercurio:
Nope, because Transformer misses the mDNIe image converter chip.
[Galaxy Tab 10.1 Android Development] supercurio:
Oh NICE !!

I was wondering if it would work on Galaxy Tab 8.9 as well, thanks for the confirmation!

However it's perfectly possible the end result is not accurate in a colorimeteric point of view, because the 2 profiles are calibrated for the 10.1 screen characteristics.
[Galaxy Tab 10.1 Android Development] supercurio:
As a matter of fact, it doesn't affect battery life at all

− nor reduces graphic or 3D performance.
[Galaxy Tab 10.1 Android Development] overhaze:
Noting can be done with screen filters?
[Galaxy Tab 10.1 Android Development] KING SKILLZ:
tried both settings on the game samurai 2 since its a color filled game and I'm really digging the 65k white. I don't use warm settings on my epic touch 4g or my TV's but it comes across good here.
[Galaxy Tab 10.1 Android Development] RieGo:
is there any way to set a screen profile on boot?

or do we have to wait for the "full" app?
[Galaxy Tab 10.1 Android Development] hoss_n2:
Does both galaxy tab 7510 and 7500 have the Samsung mDNIe image processor ? And what about the original tab
[Galaxy Tab 10.1 Android Development] sudhirkhanger:
Tried it but not sure what it does.

I have two tabs on top Voodoo native white #1 and Voodoo 6500k white #1.
[Galaxy Tab 10.1 Android Development] wlighter:
U have to give it root permission... sometimes u have to manually bring superuser app first if it didn't auto prompt..

On another note plz plz bring back voodoo sound for sgt10.1
[Galaxy Tab 10.1 Android Development] sudhirkhanger:
Thanks for the help. I can see the difference. Are both native white and 6500k white custom profiles? Or native white is Samsung's default profile?
[Galaxy Tab 10.1 Android Development] nakedninja42:
I think both profiles are from supercurio. Doing a reboot resets back to samsung profile.
[Galaxy Tab 10.1 Android Development] supercurio:
Yes both Galaxy Tab 10.1 GT-P7510 and GT-P7500 uses the same mDNIe controller, implemented in CMC623 chip.

BTW most Samsung LCD devices use this one as well.
[Galaxy Tab 10.1 Android Development] the2rrell:
This is great SuperCurio

First my Infuse and now my Tab......Keep it up. works great on both Bruh.
[Galaxy Tab 10.1 Android Development] sudhirkhanger:
Are their going to be more profiles once this is in beta or stable phase - like a night reading profile the screen is just too bright in dark?
[Galaxy Tab 10.1 Android Development] supercurio:
Do you think screen is still too bright in some conditions even at lowest brightness level?
[Galaxy Tab 10.1 Android Development] xManMythLegend:
I dont. I think its fantastic. I rarely have my tab over 50% brightness unless Im somewhere with alot of light.

Lowering brightness down results in what it should IMO.
[Galaxy Tab 10.1 Android Development] sudhirkhanger:
It too never go over 50% but when it's completely dark like reading at bed time, even at completely turned down, it looks too sharp and bright to my eyes. It might be my personal preference but that's what I feel. Thanks for great work.
[Galaxy Tab 10.1 Android Development] xManMythLegend:
Might be... but hopefully theyll be setting to accommodate more needs.

Anyone have issues yet ?

Tab randomly froze up today. But froze again after reboot. Since this doesnt load on start probably related to something else.
[Galaxy Tab 10.1 Android Development] jsaw_tab:
been using it for 3 days .. no issues on mine ...

Thanx supercurio :)
[Galaxy Tab 10.1 Android Development] Tubes6al4v:
with your thorough responses, supercurio, you are a great addition to the gtab community. When using the overlay, if I press the setting that ismalready active, I get a flashing horizontal linesthat seam to be going through rows (portrait) of the individual colors in each pixel. ie, red green, blue. However, pressing the power button shuts off the screen and once more brings it back to normal.

Hope this helps somehow!
[Galaxy Tab 10.1 Android Development] Loccy:
Am also running on an 8.9 here. Can't comment on accuracy of colours, but all I know is that your colour balance cranks down the obnoxious over saturation and makes movies look a bazillion times better.

Being able to start a profile on boot would be great, as well as revert to default Samsung profile - I note that once you set a profile with Voodoo the options in settings no longer work (ie dynamic, movie, etc - assume you guys on the 10.1 have this too)

But this is some brilliant work even as it stands - keep it coming!
[Galaxy Tab 10.1 Android Development] AceTrader:
Yes, the modes in screen settings won't work when voodoo profile selected.

Sent from my GT-P7510
[Galaxy Tab 10.1 Android Development] kokjsch:
Is it possible in motorola xoom?

Thx tto read my reply
[Galaxy Tab 10.1 Android Development] supercurio:
Nope. As already answered in details.
[Galaxy Tab 10.1 Android Development] Tubes6al4v:
As of the newest update, I don't get the screen static as before, and I'm enjoying the warmer color. Some improvements others have pointed out:

- Add button to enable 6500 in app w/o overlay. (reduce taps to set up)

- set at boot

- enable landscape mode (I never use portrait on this tab).

Great work brother! s
[Galaxy Tab 10.1 Android Development] hoss_n2:
does repooting revert the settings back to the original samsung settings
[Galaxy Tab 10.1 Android Development] siggehandf:
Where do we rub to get you to look into the digitizer settings? The tab is horrible atm.
[Galaxy Tab 10.1 Android Development] Sagui:
OMG, so seconded! Please someone, anyone, increase the number of touches reported. It's the one thing that's not perfect with the tab IMO.
[Galaxy Tab 10.1 Android Development] supercurio:
sorry digitizer sensitivity stuff is not my priority ATM (too busy!)
[Galaxy Tab 10.1 Android Development] mabalito:
Hey supercurio,

I just updated to the latest version on the market. Now I can't use it anymore.

The thing is, I have modified some values in the build.prop to fake my GT-P7500 as a Xoom. I've done this to get access to apps which is marked as incompatible with the Tab but which I know works just fine.

And then you go ahead and parse those values in this app which in turn tells me my device is incompatible (although it certainly isn't) :p

Surely there must be a better way to check for existence of the mDNIe controller than to parse those values?

Hope this can be resolved.

Thanks for your efforts.
[Galaxy Tab 10.1 Android Development] supercurio:
Hi,

My detection routine has to be strict, especially since I support an increasing number of devices, receive a lot of request for Xoom request as well and I need to provide accurate error messages.

However the solution to your issue is obvious here: the related apps must be fixed by their authors in order to work on Galaxy Tab as well. It would be stupid for them to refuse because Samsung tablet sales are a lot higher than Xoom ones ;)
[Galaxy Tab 10.1 Android Development] wlighter:
I just updated mine to the latest version and I felt something different. Not sure what it is but the display looks really nice... just wondering did something changed or just my eye has something wrong? I'm using the native white setting...
[Galaxy Tab 10.1 Android Development] supercurio:
No change or I would have named it #2 ;)
[Galaxy Tab 10.1 Android Development] wlighter:
My eyes then...
[Galaxy Tab 10.1 Android Development] supercurio:
Eyes, brain, external conditions, mood :) A lot of parameters affects visual perception!
[Galaxy Tab 10.1 Android Development] Latoc:
Hey Supercurio,

do you know if it is possible to get this to work in the Galaxy Note ?

Can it be done ?
[Galaxy Tab 10.1 Android Development] tommy1971:
double that!
[Galaxy Tab 10.1 Android Development] supercurio:
Yes it can be done if I own a Galaxy Note.

I'm not convinced yet buying one is a good investment.
[Galaxy Tab 10.1 Android Development] devadvance:
I decided to use HCFR on my tab after seeing your suggestion in the Galaxy Nexus forum. I'll perform the same tests on the GN after I get it, but for now, here are my measurements on the Tab 10.1 7500.

I have the "Voodoo 6500k white #1" profile enabled using the dev app, and then I used your Voodoo Screen Test Patterns app to perform the tests. I have a Datacolor Spyder3 sensor that I used with HCFR v2.1. I performed all the measurements with the sensor close to the center of the screen.

*EDIT: I set the screen to 100% brightness for the tests.
[Galaxy Tab 10.1 Android Development] supercurio:
Hi !

Ahh finally measurements :)

Please share the graphs directly, it's easier to read !
[Galaxy Tab 10.1 Android Development] jonsoini:
Hi Supercurio, any chance you could add support for the T-Mobile USA Galaxy Tab 10.1? I emailed you a report from the app.

Let me know if you need me to check anything further on the device.

Thanks!
[Galaxy Tab 10.1 Android Development] devadvance:
I noticed that HCFR saves all graphs with the sRGB color profile. That doesn't affect the information on them though. These graphs use the same measurements as in the xls file I posted before.

[Galaxy Tab 10.1 Android Development] devadvance:
I did a second set of measurements just now, but this time I also did the saturations. I'll put the images below, but I also attached the XLS just in case.

For reference:

-HCFR v2.1

-Datacolor Spyder3 colorimeter

-Colorimeter placed in the middle of the screen

-Moderately lit room for testing (no direct light shinning on the screen during testing)

-Left screen on for 5 minutes before measuring

-No fingerprints/grease on the screen

Hi Supercurio,

I read a lots of good comment on this wonderful application. Would like to know any chance to enhance this application to include tab 8.9? Thanks.
[Galaxy Tab 10.1 Android Development] jeremy89632:
Hello mate, since Galaxy Tab 10.1 is quite similar (in terms of hardware) to 8.9, can it be possible if there's a pickup for 8.9 support?
[Galaxy Tab 10.1 Android Development] ClarkSt:
Voodoo looks awesome! But... I'm confused. I have a 10.1 that is AWESOME, color-wise, compared to any other tablet I've seen, except the iPad. The white is super bright. My issue is that I also have the 8.9 Tab and the white is a dingy dirty white by comparison. Any chance this Voodoo tuning app will work at making that white whiter? I'm literally about to return the 8.9. I love the size, but the color is just a drag. Thanks!!!

p.s. I haven't rooted either Tab, yet. No need to on the 10.1, that I know of, but I might play around at some point,. not a huge fan of HC, so... definitely inrterested in options. And I don;t want to root the 8.9 unless I get word for you'all that it will help get me a brighter white, like the 10.1 has.
[Galaxy Tab 10.1 Android Development] liquidz3r0:
So what's the point of this voodoo? Not trying to bash or anything but are you trying to make the image sharper/crisper?
[Galaxy Tab 10.1 Android Development] ClarkSt:
I can answer that. Some people don't like the "blue-ness" of the white on the 10.1, so this tool was created to make it more "realistic" - i.e.: warmer. I put it on my 8.9 Tab, hoping I could aso make it "cooler" - like the 10.1 I have - and it doesn't do that. "Native" setting is as good as it gets, and 6500 settings makes it warmer. Personally, I'm pretty bummed out, because I much prefer the bright white of the 10.1 over the "warmer" 8.9.
[Galaxy Tab 10.1 Android Development] nakedninja42:
warm is measured to be 6500k instead of what samsung did and same goes for the normal white (i think 9300k). More than anything it just better quality in colors than sharp/crisp
