Kernel and touch performance - Galaxy S II Q&A, Help & Troubleshooting

Hello folks,
with some kernel releases ( some siyah kernels for example ) the author changed the sentivity of touch screen, improving it.
With latest LP7, samsung improved the touch quality over LPQ's one.
I guess the improvement is kernel related, so in theory if i change the stock kernel for example to siyah beta5 on both systems ( lp7 and lpq ) i'm supposed to have the same touch sensitivity, making lp7 and lpq virtually the same?
I'd like to upgrade to ICS but im waiting for LP7 with european languages, if my theory is confirmed i wouldnt need to wait anymore as i could just change the stock kernel and enjoy an improved ( fixed ) touch screen performance.

I once had the LPQ firmware and it had all the different languages so try that from sammobile.com
I think LP7 has the same language options.

Changing the kernel to siyah will give you good touch sensitivity on both lpq and lp7. So you can flash it. Note that siyah 3 is still in beta, so read before flashing

[Q] Rom and kernel version.

Hi,
I just flash my S2 to MIUI 1.812, can I upgrade my kernel to speedmod k1-t22 ? Thanks!
You can use any kernel.

Just want to tell you, yes, I can install any kernel on any roms, but it may cause some problems, especially like the 2.3.5 rom.
I tested, whatever I apply speedmod k1-t22 or ninphetamine 2.0.5 on MIUI 1.8.12, also got a strange problems: the screen will keep jump back to lock screen within 3-5 seconds. The phone also becomes very heat after applied these kernel. Only the original kernel work fine with MIUI 1.8.12. Do you know what is the issue?
Its true that some kernal may not work to well with some roms.the ninphetamine 2.0.5 kernal will heat up as it is over-volted or something like that.the 2.0.2 kernal is more battery friendly and doesnt heat up as much.chainfire is always a good one too cos they stay close to standard but give you root and cwm too

[Q] Can I Flash SpeedMod Kernel on my SGS2

Hello
I'm new to this...
I was wondering if I can install the SpeedMod Kernel on my SGS2??
Why this Question:
When I rooted my decive with cf-root and odin I have chosen the Kernel with the same "version" my stock kernel had.​
Now I'm not sure if I can install any sgs2 kernel (in this case SpeedMod) or if the "version" is important.
I think that all SGS2 Phones should have the same hardware so I sould be able to use any Kernel. Is that right?
What do I have to be aware of, when I choose a new kernel?
Thanks

Yes you can, don't worry about it. Versions don't care much after all.
Thanks a lot thought that. I'll flash he kernel tomorow.
But what im interested in:
When you say the version doesn't matter why are there so many versions of cf-root? Is'nt that a lot of extra work? Why not useing only one kernel?
Cheers
Ditschi
That's for people who want to stay as close as possible to stock.
The developers compile their kernel to work with any Samsung or TouchWiz based rom.
CF Root extracts the kernels from the specific rom, adds in the goodies and presents it to us for use to root the respective rom. So basically what you have is the stock kernel with root added among other things
ah ok...
That makes sense. Thanks a Lot for the help

[Q] Is the original kernel unclockable?

So I have heard that the original kernel of Froyo (2.6.32.9 if I'm right) was not clockable. Well, the kernel seems to have got an update in the Gingerbread version (2.6.35.10 if I'm correct) and there is no more touch screen bug so it eliminates the need to put a custom touch lag-fixed kernel on it. The question is, can you overclock the stock Gingerbread kernel (2.6.35.10 if I'm correct)?
i dont think so. however, you can give it a try using the "no frills" app from the android market
OC must be supported by "more" provided frequencies in kernel. This isnt the case in ALL
android stock kernels - even on HTC and Samsung there isnt overclocking supported by stock kernels.
To use a OC app you need a kernel with OC capabilities.
That's exactly what I am asking. Is the official Gingerbread original kernel (2.6.35.10) overclockable or not? Froyo one (2.6.32.9) was not I guess.

Siya kernel

Hi al iam a newb here white a question now iam one a rarirty rom white the siya 2. 1 kernel what is the different white the darknight kernel and the 2. 1
sent from my S2
that hurt my head reading that
+++++++1+++++++
time to go back to school.
What is the difference read the siyah kernel thread and darknight kernel thread .
jje
there is a note on DK siyah kernel :
So Me and Gokahamoral (Siyah Kernel Dev) Decided to build a entirely new platform for Battery Saving's
This is a Kernel with Crazy Feature! And with Out of the ordinary performance.
This is not the regular Siyah Kernel but different and trust me really different, its build for more stability and more battery life instead of a all round performer like siyah.
Choice of kernel is your personal preference.

THE LAG!

Just flashed the XXDLJ5 stock deodexed rom by Wanam. Before flashing I removed all the apps that I felt were useless/bloat. Flashed Siyah kernel 1.7rc3. Overclocked CPU to 1.5GHz. Overclocked GPU to 600Mhz. But the frequent lags when opening Phone and Contacts is still there! And very rarely when opening others apps or showing in-app transitions, but rare. Has anyone come up with a fix/ combo of rom+kernel+settings that gets rid of it?
Thanks in advance.
go back to ics, project butter killed this phone.
XXDLJ5 is a steaming heap of.
go back to XXDLJ4.
Sell ur phone and buy a i9305 and taste the feel of project Butter
I'm on DLJ2 deodexed with Jkay firmware, Siyah Kernel 1.7c with dual boot to 2nd rom Paranoid Android.
Everything works perfect except the dialer and contact lag. Project Butter is smoooooooth.
Perhaps a bad flash? maybe going back to previews firmware that were working for you might help.
You may want to try Wanamlite DLJ4 latest alpha built with Jkat firmware and Siyah 1.7c.
Good Luck
