just a quick note to let you know that synapse is proprietary software, in case you hadn't take note. this unfortunately means i can't use your kernel.

its license (here) is a restrictive, non-free license. in particular:

Toughy touchscreen

Hi,

Just installed your kernel 18/01 to test it.

- No Synapse & No STweaks installed (yet)

- Stock CM11-M12.

Touchscreen has become "tough" or let's say: it needs more emphasis while touching (ms?) to react (for sliding; no lag for react in a "touch") than stock kernel.

How could I find previous builds? (already found it thanks to gsstudios). Thanks to the dev for the effort.

Edit: Well, I need to add that this "resistant" touch in build 18/01 disappears at the moment you plug the phone in charge (via USB to PC in my case). And reappears at the moment you unplug again. Please, someone can confirm? When plugged, the experience is very very good (I'd say even too fast xD).

Yesterday afternoon I flashed your 18/01 kernel on top of 05/01 SlimSaberKat on the I9100 of my girlfriend : I was able to reach 1400Mhz of CPU, and 520Mhz of GPU on step 4 with 1150mV, recording this result

Apart from touchscreen bug (I set Sensibility to 100% but still present into some menus), the device is still fast and smooth, very impressive for a top smartphone of 4 years ago..
[Galaxy S II Android Development] marouane80:
Hi,

I put here my settings for gustavo's kernel 18-01 build (only).

What you get :

1-better cpu performance : smooth scrolling with "Zero" lag.

2-very good battery life.

I don't use any app (synapse or stweaks ... very useless for me). All the magic is in init.d folder and build.prop.

Please uninstall any app before flashing (cwr) !

Warning : don't edit, you may have errors if you don't know what are you doing !

Goodbye :good:
[Galaxy S II Android Development] RuffBuster:
Tried using your zip you have provided with the latest release of this kernel in combination with Markox CM build but I'm still suffering from lag especially with Google keyboard's swipe function.
[Galaxy S II Android Development] Saber:
Yes. Same here. I have already advise gustavo on github to revert the screen responsiveness commits.
[Galaxy S II Android Development] marouane80:
I don't know what are you using (saber or markox..) these are not official builds (different libraries and modules). I use only cm11 nightlies and believe me i have no lag or any other problem on keyboard. Other roms may have bugs (outdated), so think about this ! Please, try to use latest "Official" cm11 build for Galaxy S II from here : http://www.cmxlog.com/11/i9100/

gustavo build his kernel from official cm11 commits
[Galaxy S II Android Development] Saber:
Dunno if it's just unofficial roms. No thanks, I'll stick with slimsaber, better battery efficiency anyway. If his kernel was working previously, obviously the problem can be fixed. Official or not, I know what I'm doing. This is a custom kernel, not a cm only kernel.

cm11 commits are only cherry picked by gustavo and doesn't mean his kernel is based entirely of cm11 source.
[Galaxy S II Android Development] marouane80:
I said "try" not to move. As you like
[Galaxy S II Android Development] Saber:
Please don't call stweaks or synapse crap. Developers (including the kernel grandmaster gokanmoral) made these apps and spent lots of their free time perfecting their app. You must respect that not everyone is a wiz at android. I don't want to argue with you but I just want to inform ;)
[Galaxy S II Android Development] marouane80:
Before, i had touchscreen issue too. It was related to governor with wrong frequency and GPU overclocked.

Man, are you alive ??? Stweaks is oudated (2012). Today is 2015 !!!

Synapse is just a GUI to use init.d scripts. I edit scripts myself and i don't need it !
[Galaxy S II Android Development] Saber:
I didn't say it was up to date. And I didn't say he was still working on it. And I didn't say that you had to use it. All I wanted to say is not to use the word 'crap' as it will offend some users. That's enough OT already. Any more OT and ronnie will need to clean up the thread.

Update: There's no OC in GPU in Gustavo kernel's stock values!? Do you mean CPU? Apparently that's how synapse behaves when you raise the max CPU frequency so the settings stays at the highest (not applied on first boot). Touchscreen still a bit unresponsive for me. Using stock values and default everything (if that helps).
[Galaxy S II Android Development] marouane80:
no man, u r wrong, GPU overclocking is really there but i don't use it ! it gives me lag

(only gpu voltage control is not allowed)

why you don't just try offcial cm11 to see the difference ?
[Galaxy S II Android Development] Saber:
I said there is no OC applied by default (aka. Stock values aka default value). I know it's there. I've compared to dorimanx kernels values and they seem quite close to stock values (as described in the apps themselves).

Thanks for the suggestion but i'll just wait until an update comes out. I don't have time to flash it right now.

Have you read lanchon's trim fix kernel OP? Many factors could have affect the read/write speed like ongoing processes or benchmark inconsistencies. You may get some performance increase in some areas, and even decreases too. But generally, trim is a good thing

[Galaxy S II Android Development] chrhei:
Trim will be performed once a day automatically, or you can use the command fstrim. Nothing additional is needed.
[Galaxy S II Android Development] mauriciognr:
Thanka for reply, so do i need lagfix app yes or not?
[Galaxy S II Android Development] Cirra92:
In order to perform TRIM, yes you need lagfix app. But note that the one from Play Store is incompatible with S2, so you have to download from appropriate thread from xda.
[Galaxy S II Android Development] fragel:
So it's lagfix what do the daily trimming? otherwise we need to use:

su -c "fstrim -v /system; fstrim -v /data; fstrim -v /cache; fstrim -v /preload"

which in addition will trim the /preload partition ?
[Galaxy S II Android Development] chrhei:
Gentlemen, I like facts only, no half-truth:

Please read the original TRIM thread for the I9100

..... alternatively, instead of using lagfix you can run one of these commands (these are better because they also trim /preload)

..... android 4.3 and later should trim all writable file systems each night during charging automatically

So no need for additional tools or trimming manually if it seems to be uncomfortable for some people.

Regards,
[Galaxy S II Android Development] fragel:
Thanks for your flatly answer, and for sharing your preferences.

I read Lanchon's thread before trying this kernel, but as I didn't follow from CM10.1 the dev history of the I9100, I got a bit confused with features. That's why all my last post is a question and so part of this.

So, current builds (> Android 4.3) of CM11 (or based on) are already being trimmed daily. No difference of the Stock kernel or a modified TRIM enabled in this case?
[Galaxy S II Android Development] chrhei:
To use trim you need a trim enabled kernel/rom, stock won't work.
[Galaxy S II Android Development] felipevsw:
Touch is working flawlessly on the new kernel! Nice work, guys!
[Galaxy S II Android Development] Saber:
I don't know why people just can't read instructions. If lanchon said us to use lag fix in the instructions, we should use it. We only need to use the app once , don't have to use it daily. It wasn't an alternate option or an option you could leave out if you wanted trim, you could do one or the other

If you didn't know, the /system, /cache /data partition don't trim themselves after installing the kernel with a trim compatible rom. Ask lanchon if you want better explanation.

---------- Post added at 09:02 PM ---------- Previous post was at 08:56 PM ----------

No. Stock kernel doesn't have trim at all. Lanchon's kernel and this kernel has trim. It has to be enabled first then it will automatically trim your partitions while you use your phone. You won't see the difference if you don't use fstrim command or lag fix app on your phone (google and download from thread).

eMMC Bug!

I installed this kernel with the CM11 Nightly 25.01.2015

I use the i9100 Samsung Galaxy S2

Light bugs:

The phone is slower than on Apolo 3.2 Beta 3 Kernel

The phone needs 5 Minutes to shut down. (With the Popup, that it is in the shutdown progress)

Restart into recovery is impossible, it shut down.

Now the heavy Bug:

After a few hours the phone freezes.

I restarted it with pressing the power button 30 seconds.

First try: Bootloop in the screen with the Samsung logo and my yellow triangle.

Second try/reboot: Android booted succesfully but the /data partition got corrupted!"

Some Apps are okay, some APPS lost its data.

Some desktop icons are lost, some settings in the system, too.

And some deactivated apps got activated again....

Yes yes, that's what I meant, without reboot :) As a matter of fact, not a single lag for those 220 hours :) It could have gone much longer I am sure, but I had to reboot in order for Xposed to start working.

Do not use the lastest version! I repeat do not use the lastest version !

I have been using this kernel, one and only, for half a year. with a heavily customized Neat ROM 4.4.4.

When a new version came out, I read the logs carefully, but will install anyway, tried for a few days in every way, then if it's okay and feels right I keep using it. If it's worse then I switch back and wait. It happened for 18th day kernel when I had touch issue, I switch back to 5th day version.

But for this 24th version, I felt something was off. Soon after installation, my phone lost its sound, the speaker won't work. I wiped kernel and reinstalled, it was fine in the beginning but soon after an hour the phone stop ringing again. I knew something was wrong. Then some apps began missing, I used root explorer and saw the files still there but the phone won't recognized them.

Then I read the logs and saw TRIM was implemented. I moved to Lanchon's thread and saw some serious warning about brickbug on eMMC chips. My chip is V00LM (or so) and is in the brick list. I read somewhere about the fix for >4.3 but I can't be sure if we keep using custom roms it is always included or not. But I was freak scared and revert back to 05/01 version immediately. Everything has been perfect again.

Gustavo, I believe the new feature you implement into this version is not good. I appreciate your hard work and if I could I'd donate to you without hesitation (I'm living in a third-world country). Just wanna let you know you've been doing great and are a savior to unknown people from anywhere in the world like me :D. Keep it up !
