I think my Cappy finally reached Froyo perfection.

My combo: Perception 10.2 (+ minor personal changes), latest SpeedMod kernel and ZNKP1 modem, simply the best, my Captivate is fast, stable and battery life is awesome. I had bought a USB charger to have it at work and I definitely had to use it around noon every day cause the batt was down 50% and didn't last til my ride back home. Since my combo is up, I've practically forgot the charger, seems like my phone has a 3000 mAh, that's how incredible is the difference, I got home, take dinner and have time to browse, listen my music, YouTube, play Slice It, you name it and after 15 hours of normal use (no auto brightness, set to 50%) I plug my phone back to its meal with 5% left.

Thanks designgears and hardcore!!!

NOPE... I was the one that put this before but without pics... NOW I'm showings the the wifi has the same time of battery use...
[Captivate Android Development] ryude:
On K12T, I was on the phone for 1 hour 30 minutes or something. I noticed that throughout the call it would light the screen up and I'd have to take my face away then put it back in order for the screen to go back off.

Hope you get this fixed, love the kernel.

i897 boot screen

i switch the atntlogo.jpg thru adb, i m wondering if possible to change same way the i897 boot screen jpg or i need more advanced technical skills? thanks
[Captivate Android Development] lrs421:
It's in the kernel, if you don't know how to compile kernels you wont be able to do it.
[Captivate Android Development] GGXtreme:
It's to correct the color bias of some Captivate screens. Some batches have slightly blue-tinted screens (corrected to neutral with warm kernel) and some have slightly yellow-tinted screens (corrected to neutral with cold kernel). If your screen already displays non-tinted whites and accurate colors, the regular kernel should work fine. However, I've noticed that the warm K12T-warm kernel isn't warm at all, while K12S-warm is just fine.
[Captivate Android Development] DrGoodspeed:
thats weird, the same thing just happened to me. before (i think it was on the same rom and kernel) i set my wifi to sleep when screen off and i checked the battery usage and it was only running like 60% of the time. i just checked again and my policy is still sleep when screen off, but its been running 100% of the time. it doesnt really matter tho becuase its still only like 6% of the battery and im gettin amazing battery life
[Captivate Android Development] krips2003:
Well, I'm not having those issues at all. Mine sleep policy for WiFi is working as it should be.
[Captivate Android Development] mattsternc:
Where do I find the WiFi sleep policy screen? I saw a screenshot of it a couple of pages back, but I've not been able to find that on my phone for some reason. :confused:
[Captivate Android Development] olo567:
Go into settings, Wireless and network, Wi-Fi settings, then press the menu button from this screen and click Advanced. Wi-Fi sleep policy is hidden there.
[Captivate Android Development] mcx6:
Settings, Wireless and network, Wi-Fi Settings, menu, advanced, Wi-Fi Sleep Policy. If you have Spare Parts app installed make sure WiFi Sleep Policy is set to Android Default, or you may run into problems with it not shutting down.

Under SpeedMod Options---->LagFix there is a Enable Lagfix...DATA EXt4 then there a Convert System Ext 4/RFS is it Recommend to do Both Data and System to Ext4?
[Captivate Android Development] kamots:
I have been wondering this as well I know voodoo extension 4 converts system partition but I wasn't sure about this 1
[Captivate Android Development] SweetwaterBurns:
I've had some issues with the conversion of system messing up the root on various roms so I don't even mess with it anymore unless I'm planning on flashing a new one.
[Captivate Android Development] beerbaronstatic:
The easiest way to fix that is reinstall root/super user from recovery, fixes the issues for me so far
[Captivate Android Development] DrGoodspeed:
did u check using the battery usage in sgs tools or sgs info? my wifi is only 6% of the battery but its been running the whole time even though it shouldnt be
[Captivate Android Development] DrGoodspeed:
nvm. i checked again and today i turned my phone back on and had the screen off most of the day. it says wifi has been running only 6.4% of the time, so i guess the wifi policy is working again. or it was always working
[Captivate Android Development] DrGoodspeed:
i do it and havent had any problems
[Captivate Android Development] Exostenza:
Any way there could be a version of this kernel that has normal auto brightness settings? I switched over to reoriented by xcal because this kernel makes the screen too dim which really ruins having such a nice screen. I noticed that with xcals kernel not only is my screen brighter, but my phone is faster and has better battery life so I see no real reason not to have a version with the normal brightnesses. (Note better battery life could have also been going from the JL3 to JK3 modem)

That would be great!
[Captivate Android Development] MikeyMike01:
For the billionth time, it does not make the screen dimmer.

It makes the lowest setting lower, the highest setting higher, and adjusts the automatic brightness to more reasonable levels.
[Captivate Android Development] Dxtra:
Yes it does make the screen dimmer under any condition compare to stock. I completely disabled auto brightness since it's to low under certain lights. BTW under no light it's perfect. Also one thing I notice when under no light but with house TV ( also under low light level ) on auto brightness its constantly adjusting never had that problem with stock.

[Captivate Android Development] MikeyMike01:
It's brighter when you're outside for example.

Bottom line, this is what Samsung should have given us.

Dogfood test version: K12U-T4:

- Using O3 compiler optimizations (faster) except for sound/soc/codecs

- Kernel scheduler tweak modified:

- - - Less over scheduling, hopefully better response and battery life

- Warm version is warmer

- Slight tweaks to color balance (less green)

EDIT: Cold and Warm versions rebuilt.
[Captivate Android Development] krips2003:
I fully agree with you + automatic brightness setting on speedmod kernel, imo, is the best for any kernel out there for captivate.:)
[Captivate Android Development] krazyphire:
I think for some reason people don't understand that auto-brightness should use the sensor to brighten or dim the screen relative to the environment so unless they're in the sun all day the screen won't be as searingly bright as stock. Hardcore has greatly increased the accuracy in my opinion and I don't have to wait hours now after I turning off the light to look at my phone in case my eyes burn
[Captivate Android Development] Barbarian:
Agreed

After flashing K12U warm my video camera does not work. says "camera failed". Tried flashing back to T and still says same thing. Tried clearing dalvik cache from recovery, no help.

Anyone have a suggestion besides reflashing?
[Captivate Android Development] DrGoodspeed:
Yes I love the brightness settings and hope hardcore keeps them the same
[Captivate Android Development] ease_the_pain:
I am using K12U warm since it was uploaded , never had an issue like that + battery life seems better than T version to me.I am using it with serendipity 5.0 , maybe your problem is ROM related.
[Captivate Android Development] clemmie:
I read somewhere in this thread that in order to clear more RAM, 720P is disabled on the video camera. Someone correct me if I'm wrong. You'll have to do a search to find out how to reenable it.
[Captivate Android Development] silverslotcar:
That is if you get the BIGMEM version, it has no 720p recording.
[Captivate Android Development] MisterAnthonyxD:
Hardcore has several options, one being the one you mentioned(BIGMEM). That one does disables 720p so I would flash his regular versions.

[Captivate Android Development] mcord11758:
How are you trying to get to clockwork
[Captivate Android Development] lrs421:
Sounds like your trying to use the rom manager GUI, not good thing to use with this kernel. If you can still flash as normal by entering recovery mode via the extended power menu.
[Captivate Android Development] SkitchBeatz:
I wish there was a BIGMEM/Cold version
[Captivate Android Development] Johnston212:
Just curious, but is anyone noticing battery issues since K12T? I've been using K12T and recently changed to JK4 from JL2 and I've begun noticing an increased battery drain. I disabled HSPA, never use wifi, samsung apps are disabled, and most syncs are set to 5+ hours, yet I'm still receiving battery bleeding.

I have tried reflashing K12T, which fixed it the first time I had issues with it. Anyone thinking that reflashing the modem would possibly help?
[Captivate Android Development] SeanHacker:
great job on these kernels! makes my phone smoooooth, and the battery life is amazing!!!
[Captivate Android Development] krazyphire:
The ritual I use everytime I flash is to flash at 100%. Boot the phone once then boot back into recovery then clear cache, and dalvik cache. Then let the phone go through 2 full power cycles charging while the phone is off.

Sounds like a lot I know but after recalibrating my battery last at least 30hrs with a max at 41hrs which is what I just hit today. This may also be the combo of the rom and modem. I'm using Darky 9.1 and the KNP1 modem. JK4 always seems to drain my battery so I stick b/t JL3 and KNP1

Good luck! :D
[Captivate Android Development] hardcore:
K12U just released has better battery life.
[Captivate Android Development] Johnston212:
Thanks. For some reason, KNP1 wouldn't really 'shine' until I reflashed it. I broke my record on 3G dl speeds. I hadn't tried clearing caches yet. I noticed somebody posted how they had problems after clearing Davik cache.

So, what I need to do is to obviously update to K12U, then clear the Dalvik cache and what other cache? After that perform two charge deaths? Sound about right?

Can I flash this kernel using neldar's SGS kernel flasher?

If yes, which one is the best. ODIN version or CWM version? Sorry I'm a noob :)

Thank you.

download and unzip the odin version, then select the .tar file with the kernel flasher.

[Captivate Android Development] bamonkey:
or you can grab either one and just let the kernel flasher find it for you in the zip. ive even let it grab the kernel from an entire rom once just to test this :cool: i prefer the cwm version just in case i find myself stuck in recovery *thumbs up for thinking ahead*

Determining which kernel I'm running

I'm having a problem determining which kernel I'm running. When i had Phoenix 4.5 running it would give all the kernel info. I'm now running Cognition 3.04 I installed t12u-t4 cwm and it still says kernel version 2.6.32.9. The new kernel installed, so why don't I see the full kernel info?
[Captivate Android Development] lrs421:
I9000 roms show detailed kernel info.

Download error on the website.

I'm trying to download K12U and the site says it's been downloaded to many times. Is there another place to download it?
[Captivate Android Development] hardcore:
K12U was just out, but here is K13A-T1!

Changes:

- Single version for neutral/cold/warm color, selectable from Recovery

- Option to disable darkest auto-brightness level, selectable from Recovery

- Minor optimizations to brightness sensor driver

Otherwise it is the same as K12U.
[Captivate Android Development] TonyStark R.I.P.:
So how do I determine whether I'm running the new kernel or not?

Anyone having issues with the headphone volume control and the new voodoo app? Seems as if now (not sure if its kernel or software) but my volume keys are mapped to the control of the headphone amplifier in the app.

[Captivate Android Development] joeshmoe08:
Cold adds a tint of blueish color on the phone. It is for people who have a "warm" captivate (yellow tinted) so it makes it neutral.
[Captivate Android Development] Johnston212:
Yeah, that's how I did my first flash, but since then I've been doing them all via CWM. Makes it easier on the go and I've never had a problem
[Captivate Android Development] Johnston212:
Lol, K13A so soon? I figured we would at least have to go through the entire alphabet first. Looking forward to the stable version.
[Captivate Android Development] Johnston212:
Yeah, we know that. I'm having the same problem because it doesn't say WHICH tweaks to activate. I'm guessing its the one's with the (R) on them?
[Captivate Android Development] geokilla:
Ditto. Are there also K1, K2, K3 as well? Lol =P

Just wondering, does anyone actually notice a difference between the normal, cool, and warm versions? Been using the normal versions because I don't see what's the reason for the cool/warm ones.
[Captivate Android Development] existz:
(R)=Recommended, choose the first 4 tweaks, you can enable logger if you need logcat, and you can enable the IPv6 privacy extensions if you want, also if you don't know what tun/cifs is you don't need them, they are not tweaks, they add support for tun and cifs

Read the first page, I have a mini faq in the last post

Some screens are ok, some are to bluish (needs warm version to even it out) and some screens are to yellowish (needs cold version to even it out). If you can't tell a difference you should be ok with the normal version then, no need for warm/cold. As mine is a tad bit yellow, I would need the cold version
[Captivate Android Development] geokilla:
I keep on clicking Thanks instead of Quote >.> Thanks for the explanation though lol

Do you or are there pics here on XDA or somewhere that compare the bluish/yellowish tints and stuff that you guys talk about?
[Captivate Android Development] GGXtreme:
Well, technically you can't compare accurately with pics, since the tints you'd see would be dependent on the screen you're viewing them on (and/or the camera the pics were taken with). However, here are a few simple comparison pics between Captivate/Vibrant screens:

http://img.photobucket.com/albums/v494/itskeeno2/captivate/DSC01597.jpg

(The one on the left is closer to the correct warm white, the one right has a noticeable blue tint)

(Once again, white on left, blue on right)

http://androidforums.com/members/samsungvibrant-albums-blue-tint-picture2174-browntint.jpg

(Two Vibrants side-by-side: the one the left is a bit warm [color-ramping unevenness in red subpixel], the one on the right is a cold blue)
[Captivate Android Development] geokilla:
Ok yea those pics are pretty obvious to tell. Is there an application that lets me determine whether I have a tint on the screen and what not?

Forgive me for the newb question, this is my first Kernel flash.

I've flashed, but when I look in About Phone, the Kernel is listed as 2.6.32.9

Nothing mentioning speedmod or anything like that. That doesn't seem right, is it?
[Captivate Android Development] beerbaronstatic:
Not all ROMs report the full info, so its probably right, if you boot into recovery it should have mentions of speedmod settings I believe
[Captivate Android Development] olo567:
Probably not. You can try looking at the same image on your phone and on a PC monitor. Monitors are almost always poorly calibrated, but at factory settings tint is the one thing that's usually right. You should be able to compare to see if the warm, normal, or cold versions get it closest.

[Captivate Android Development] Spidious:
OK tried the firebird kernel and kept shutting down by itself. So I am back, how do you get to the brightness setting disable ?
[Captivate Android Development] xreflection:
I believe its in the recovery menu.

EDIT: Just flashed K12U...its so smooth...but it might just be me. But regardless, Me likey.
[Captivate Android Development] GGXtreme:
That wouldn't really be possible, since the signal going to your screen is the same regardless if the screen itself is warm or cold. However, you can download a program like Total Benchmark which has a bunch of screen test patterns. You can compare solid white on your screen with a calibrated computer monitor or TV. The 'Master Pattern' and 'Color Scale' are also useful in finding uneven ramping in colors that may result in an overall warm or cool tint (if your screen is pure white, you should only see white, black and shades of gray, no pinkish/reddish/bluish tinted areas on the pattern).

I also had an interesting experience with K13A and the latest Voodoo Control App...somehow the service incorrectly determined that my headphones were plugged in and set my media volume to maximum, blasting The Faceless during my discrete math class >_>;

My bluetooth is absolutely unusable on my phone. Whenever I make a call there is static to oblivion.

I've flashed this kernel using kernel flasher yesterday. I got a problem with my battery. The battery is drop so fast even only on idle, faster than before using this kernel. Is it normal at the first time? I use the first 4 tweak on recovery and lagfix --> change the RFS into ext4 (data only). Any suggestion on battery usage? Thank you.
[Captivate Android Development] olo567:
Are you running Cognition? Or another Captivate ROM? A Captivate ROM with I9000 kernel/modem will break bluetooth.
[Captivate Android Development] doreyu:
something that is always good is wiping the dalvik cache in the CWM advanced options and letting your phone rebuild it after flashing a kernel (it will take ur phone about 5 mins to boot).

there are a ton of battery recalibration tips around these forums. my battery life just got cut in half after flashing something and not having time to properly recalibrate. so what i am doing now is charging to full when the phone is off, once it reaches 100%, unplug and turn it on, once it fully boots turn it off again and replug in the phone, it will take another ~10 mins to get to 100%, after i wiped the battery stats in CWM advanced by booting into recovery. im going to let it die now, and recharge fully again during 1 charge, hopefully that will work.
