ShadowKernel v1.0.4 & v1.0.4+OC/UV

Hope everyone is having a good holiday weekend. This new version has a small but significant tweak to the default Voodoo Color values. You'll notice right away that the samsung logo doesn't have that nasty yellowish tint, and your bootanimations should look better too.

For anyone that doesn't use the voodoo control app, or just doesn't want to do any major messing around with the color settings, you should have a much better appearance from the start. The same disclaimer still applies: Not everyone's screens or eyes are the same so these settings will not appear the same from phone to phone. Possible further adjustments might improve your colors, but hopefully this is less necessary than before. Thanks to kennyglass123, RandomKing, SenseiSimple, & jeffro18 for testing and confirming the better settings.

To anyone who already has set colors you like, this will not affect your saved settings.

I just installed and tried both kernels and the colors were pretty consistently fantastic. Thanks bbelos. Zeinzu, were you looking at the reflection in the phone or the colors?
[Epic 4G Android Development] flastnoles11:
Lol.... thnx for the laugh
[Epic 4G Android Development] Zeinzu:
There's nothing wrong with my screen or my eyes. It looks better than the yellowish tint but the colors are "not" correct and it has a very distinct reddish tint, especially over whites. But it never fails over at these forums that everyone trolls you if you decide to be honest.
[Epic 4G Android Development] mjh8812:
I will agree with zeinzu..there is a little redness on default voodoo settings...ill toy with it a little though because this is a your mileage may vary type deal..I'm really jealous of flastnoles because he never seems to have issues with his epic lol..
[Epic 4G Android Development] DroidApprentice:
I think 1.0.3 and before look gorgeous on default. So until other new features are added I'll wait to update. Kind of tough to believe I've flashed more than one kernel by now!

No I sure don't and when I do I don't come on here *****ing about it! I fix it myself. If you don't like the color settings this kernel comes with just f'n change them and move the f along! Its really as easy as that! And I don't have problems because I take what I like from these kernels and roms and make my own and don't use what I don't like... therefore nothing to ***** about. Learn something and you might not have to ***** either!!!!
[Epic 4G Android Development] Nashdogg:
Exactly, I think those settings are fine. But if I didn't like them its just as easy to change. There not permanent.

[Epic 4G Android Development] jeffro18:
I reported seeing fairly significant differences in my two phones while applying the same settings. These settings look very good on my phone, but the blues are much more vivid on the lady's phone and I need to tone them down. Hardware differences will make it hard to find a happy medium for a baseline. This is a first attempt at making the baseline colors a little closer to something everyone can be happy with, and require less tweaking than before. This is also an effort to make certain boot animations look better. Feedback from more sources is the best way to try and dial it in.
[Epic 4G Android Development] SenseiSimple:
I can confirm the SLIGHT reddish cast to whites and noted this to bbelos in the test version of 1.0.4. Given that it's Christmas and all, i'm sure he hasn't had a lot of time to do much else with it.

If it bothers you, you can set the red gamma offset down by one or two points (-1 or -2) from wherever you have it, should be good then
[Epic 4G Android Development] KennyG123:
I have one of the original Epics about 2 weeks after release and the colors look freakin amazing on my phone, no reddish tint. I was the guy who was Not a fan of Voodoo color but may have had my opinion changed by Bbelos great work here! Merry Christmas B and thanks!

Lol at all of you, seriously. I'm not even using that version so how do you assume I'm *****ing about it? I posted my feedback of the color settings and gave my honest opinion of what I saw. Nothing more nothing less, trolls. Merry Fcking Xmas to all of you too, rofl.

[Epic 4G Android Development] Zeinzu:
It's troll like to give honest feedback? News to me buddy. So sorry for having my own feedback on settings and sharing it with a public forum...

You all talk like I said "wow this kernel sucks now" or "wtf were you thinking your stupid for using those settings"

I made no complaint. I gave my honest feedback of the settings after trying them. I've always had nothing but incredible things to say about this kernel and it's developer. I give one negative feedback about something and immediately see 5 or so replies saying how I'm *****ing and this and that. THAT'S trolling...
[Epic 4G Android Development] Devtodi:
Does anyone want to put up what they believe to be the best color settings fro 1.0.4? I would like to try out some settings that don't break the bank batterywise, something bright but efficient but I am not sure how to configure the settings.
[Epic 4G Android Development] DroidApprentice:
Isn't there something like color bars available and a greyscale so you can use some objective guidelines for your adjustments? I haven't tried the voodoo app yet but would expect it's included there.

Yea I know your not. However that's besides the point isn't it, your trolling me here and I did nothing wrong. You've been trolling me in every thread I post in for about two months, actually. Everytime I say something. If it's positive, negative, or completely indifferent you always have some comment about anything I have to say. "You" obviously don't get it, so go back to your trolling.

[Epic 4G Android Development] KennyG123:
Zeinzu and Flastnoles agree to disagree and move on guys. Let's get back to the awesome kernel discussion. Perhaps constructive feedback instead of "OMG these colors are awful" better would be "defaults are too red for me, these look better for anyone else that has that issue" and posting good values. Voodoo color has been so varied across all our phones. Mine the defaults were the best out of anyone elses I tried. Let's keep it civil and try to avoid the back and forth towards each other. Arguments should be taken outside, PM each other. Thanks guys. Happy Holidays!
[Epic 4G Android Development] flastnoles11:
You are absolutely correct! And sorry for getting off topic... and also sorry to you zeinzu for being a bit of a d***... this holiday was pretty painful for me for some personal reasons. Sorry for taking it out on you...
[Epic 4G Android Development] BigOnes69:
I have and cleared it up by changing the settings. I went with the default settings in 1.04 and they are great for me the specifically the whites. No more having to adjust the yellow. Thanks
[Epic 4G Android Development] pixlz:
Of course, your mileage may vary.

Newest shadow kernel(1.04) definitely has improved default voodoo color with this rom.

If you already tweaked your colors, this need not apply. If it ain't broke for you, obviously don't "fix".

I ended up skipping personal color tweaks when I updated to thunderhawk 3.3, so its a nicely seen benefit. It strikes me it'd be easier to tweak from this color base as well even if its slightly off for said user. samsung logo isn't a drastic color difference anymore. Whites are more... white. Startup animation is nicer looking too.

Good stuff. :)
[Epic 4G Android Development] mocsab:
MTD ?

I did benchmark tests comparing the "Shadow" kernel with several others and consistently got higher benchmark scores - considerably higher benchmark scores with the ShadowKernel installed - versus the Samarai - Nubernals - etc - I have since moved on to the MTD version of Marcusant's revival and I am curious if you plan to do an MTD version? (hint hint)
[Epic 4G Android Development] kstephens98:
So glad to hear someone is looking at helping xboxfanj with kernel development.
[Epic 4G Android Development] A_Flying_Fox:
Wow wtf I just put those setting in my phone. Its ****ing disgusting how can you not twitch at the obvious off-white yellow-pink tint when viewing a black page?

LOL but nah no one trolled you bro....trolling is when you say something JUST to piss someone off....if you happened to get mad when someone argues with you, that's just a short temper lol

It was just dickish the way you came off at first....homeboy put mad work into his kernel and you just come up and say "youre ****ing stupid for thinking this looks nice. Are your eyes ****ed up you ignoramus?" Instead of saying "wow...I just put these on but it was kinda red for me. Wow its so cool how everyones phone is obviously different if your phone gets white where mine gets red under the same settings! Thank you for also explaining this was a BASE and to get my colors right I only had to change a single variable :O"

With that being said, I'm still on 1.03+ since the only need to update is if you were too lazy to set your own voodoo profile, correct?
[Epic 4G Android Development] bbelos:
I will work on an MTD version when the time is right for me.

This update is not an issue of people being "lazy", it's more of me not being satisfied with the results from the initial voodoo color code i used (which i admit, i'm sure is still not perfect). But at the time, it was functional and I released it to get some feedback, which I greatly appreciate from everyone.

That said, if you already have settings you like to use prior to v1.0.4, i fully encourage you to continue using them. Even if you do update, those settings will not be reset. If you are unsatisfied with the colors during bootup (samsung logo & bootanimation), then I would recommend you to update and see if they are improved.

For those few whose bootup colors looked ok, I would be interested to hear if they are no longer ok with v1.0.4, or if they indeed still improved.

Please remember that everyone's phone unfortunately reacts differently to the color settings. If you don't like the look of someone's posted settings, I would ask that you post the settings that you prefer. Those settings might also work for someone else. I for one don't like just randomly clicking different settings to find something that works, I like to test posted settings and just do some minor tweaks for my preference. There are tons of combinations that look great on my phone, it's just a matter of finding a starting point. The more examples we have, the greater chance someone like me might find a set of values that works for them.

Thank you :)
[Epic 4G Android Development] jdelano:
colors improved!

I was asked by Random to put 1.0.4 on to see it if fixed the boot animation's looks. I didn't think the boot animation for RandomROM 3.3 looked bad at all. I was wrong ;) after I flashed this new kernel and rebooted, I could see an immediate improvement in the boot animation and I love how everything else seems more crisp looking. At least for me; you've hit it out of the park with this color tweak.

Thanks !!!
[Epic 4G Android Development] Zeinzu:
I apoligize to you as well. The holidays have had me under some stress as well. And to the developer, I fully support your kernel as it's the best overall that I've used on my device.
[Epic 4G Android Development] joshag:
just props..

Love your kernels also.. just switched to MTD but ill keep following this thread watching for a MTD kernel should you release one. :) appreciate all your work.
[Epic 4G Android Development] pixlz:
You guys should also know that fixing settings in the kernel is the only way to adjust the samsung boot and startup ani.

When the majority had a tint to the samsung logo post voodoo color flash... and now the majority don't or its lessened, its a positive change.

If you like old kernel, then use it. Adjust colors in voodoo yourself for post startup use, or use a non voodoo color kernel.

Be chill and do what works best. No rom or kernel is perfect for everyone. Some peeps phones can overclock better, some screens are a lil better and brighter. Its all in the hardware, some of it manufactered almost a year apart or so from each other.

Your mileage may vary. :)

sent from my epic Epic using transparent XDA App of DOOOM!!!
[Epic 4G Android Development] A_Flying_Fox:
I used to have the bootup thing where the logo would go from white and then suddenly switch to a murky yellowish tint and then the screen would be noticeably warm and then switch to a "cool" color spectrum after its fully booted (got signal, media scanned, etc.etc.) but then after messing with it i got settings that look veeeeeery nice to me

but i wouldnt mind testing out your new kernel...how would i go about making your settings override my own?

Voodocolor is pretty easy to set up if you look at it with a "well it cant look worse" kind of attitude when youre sliding your finger lololol

My GF saw how much better Wordfeud looked on my phone with this and asked me to do the same to her's! We got both phones 2 weeks after release so the defaults worked perfectly. Don't know if that is a clue why there are such varied results. Thanks again Bbelos!

Thanks kenny, I have been wondering what anyone else with access to two phones would see. One of my phones was purchased in late 2010, the other was in feb of 2011. I don't want to admit which one of us bought it first...
[Epic 4G Android Development] BigOnes69:
1.04 looks great , no more yellow, on my phone but I noticed the following. On 1.03 I modified the /system/etc/sysctl.conf from Marcusants thread. I also had the 4g modified for faster communication by going through the ##3282# process. The problem is communication speeds are about 1500 to 2000 on 1.03, while on 1.04 they drop down to 1200 and below. They both have the same modified settings above. I have changed back and forth between my clockwork backups and have confirmed this 8 times. Is there anything that changed between the versions that could effect this? I am running Starsky ROM the last version before his thread went dead. I hope this helps clarify something..

Peace.

4g + shadow kernel + other 4g 'fixes'?

.......apropos to quoted post, am wondering: has anyone running ShadowKernel_v1.0.4 found other reliable fixes for 4g, other than above referenced? (someone had mentioned losing 4g every time 4-8 seconds after being connected).

on a different note.................I had not had a single issue whatsoever w/ Samurai (included with LegendaryROM, had found it to be very stable and snappy from the first boot-up several generations ago).............therefore, had some reservations whether to venture over to ShadowKernel ........ still, my curiosity got the better of me (thankfully!) + last night I flashed over + have to say, it's been great being able to calibrate color on this device: what a concept ..................... despite the fact that my device has not shown 'yellowing' per se in the year-plus that I have been running it, am encouraged to see a kernel developer take the step forward towards this kind of precision control of our devices.....................aside from color control, ShadowKernel feels immediately smooth and reliable, will post an update after a few more days of use...........am using 4g on hotspot to post this w/ great battery use..........so this is a good sign!

Thank you bbelos for your thoughtful integration of valuable features on ShadowKernel.........a number of us already appreciate your hard work............Happy Holidays to you!
[Epic 4G Android Development] KennyG123:
That is dependent on what ROM or theme you flashed not the kernel. Battery icons are stored in the framework-res.apk.
[Epic 4G Android Development] thomasskull666:
Which app are you using to set the governor? Just curious.

My guess is ondemand is set on boot by an init.d script, you may have to change that to enable permanent changes.
[Epic 4G Android Development] Gavisann:
Voltage control. I remember that 1.03 had a possible script problem that was fixed in 1.04, but I have this problem on both of them. I'll check init.d, thanks.

Ever since installing this kernel (all versions) my screen flashes when powering it off (one of the few strange behaviors I have seen). Is this where CRT off could go? It's not on my current ROM (an older version of Mostly Stock).
[Epic 4G Android Development] seoulseek80:
I think we might misunderstanding each other. The color of the screen goes red when the battery gets to 10% so wouldnt that be the voodoo color on the kernel itself and not the rom? Im on RH 3.3
[Epic 4G Android Development] KennyG123:
AH...the tint of the screen goes red because it dims the screen so much...gotcha! You may need to adjust voodoo color at your lowest brightness to get rid of the red. Or someone can put in a mod to not dim the screen until 5%.
[Epic 4G Android Development] seoulseek80:
exactly! Yeah 5% would be better but when i have 10% and it happens its a little distracting. lol
[Epic 4G Android Development] fastmikey1969:
Are there any fundamental changes between v1.01 and v1.03 that would affect stability? I remember 101 was rock solid for me. Had a couple freeze ups with v1.03 so I flashed back v1.01 to see if it helps.

ERA RC2.1, EI22 modem, ICS 2.1 theme (no lock mod)

Edit: oops just had a freeze with v1.01, back to the drawing board.

Bbelos....

Any chance of an MTD kernel??? I (and others I am sure) are migrating in that direction and I know I for one, am missing voodoo control...????please? And thanks
[Epic 4G Android Development] saridnour:
The color is so off on my phone?? Think it is related to what the above poster is seeing.

With this kernel the screen turns a dirty brownish red tint. I can see it in the boot animation where it shold be black as well as throughout my OS. I have my display set to about 5% brightness which makes it show even more. If I brighten it more it goes away BUT I set it low to save power on purpose and use phone weaver to scale it depending on if I am home or work (low) or out and about (high).

I used vodoo control to adjust it, but can't seem to get it just right. Ive looked at settings posted here and none come close. Anyone have setting that will work and setting that will stick through boot? I can live with the boot animation looking bad (as the vodo correction kicks in just after bootup) but would prefer it to just look normal? Is no one else seeing this? I can post a video clip if need be.

This goes away if I flash another kernel. Would like to try this one out but just find it odd that im seeing this issue big as day. Also it's not rom related as I have tried a few and tried them stock (cleared user data) with the same result.
