Well ace2nutzer, maybe it's not "your" fault (sorry). My problem with carrier signal comes from last summer. I came across to CM11 from a stock ROM (MG2 Poland - I8160XXMG2_I8160OXXMG1_HOME.tar.md5). I then installed CM11 (cm-11-20140623-UNOFFICIAL-codina.zip), and carrier signal losts began. I say now it's not your fault, because then I was not using your kernel. I suppose it was stock kernel. Therefore, it was later, when problems started, I began to apply your kernels to try to solve the issue. But no luck.

Even so, I can say that CM11 + ace2nutzer kernel it's the best option for this phone. Good job.
[Galaxy Ace II Android Development] MarquesYOLO:
Doubts with this steps.

First step: I understand that I should "backup to sdcard1" on CWM and then copy all files from sdcard0 to my PC.

Second : copy all files I saved in my PC from sdcard0 to sdcard1.

Am I wrong. Thanks.
[Galaxy Ace II Android Development] ace2nutzer:
Okay, i was meaning: u should at first copy all you pictures, music etc.. from sdcard0 @ sdcard1 .. because u'll format later sdcard0 ... and also it' later only 10MB .. therefore, everything @ sdcard1 ! Of course u need for that a good / big enough sdcard1 for this.

it is also recommended to make a backup of sdcard1 on PC .. and then put your sdcard1 (ext-sdcard) in your Phone again and format it over android in Settings ---> Storages ... this is needed so that it's correct formatted @ FAT32 @ 4096 Blocksize/Clustersize .. ! With that, u'll have the max. performance. After that restore the Files again from PC @ sdcard1 :)

The Problem is, when u bying the sdcard and use it without formatting or if u've it formatted on PC .. then the Blocksize is not 4096 bytes (optimized for the Phone) but something like: 16384 bytes ;) (it reduce read / write speed on sdcard1)

I've this probem sometimes too.. but for luck very rare ... i've also MG2 Modem / Baseband ... i think it's just Samsung Bug ---> Modem Bug .. but for your Phone: codina: i8160 ... there is an newer Stock ROM available.. search for "NF2" .. and then flash again the CM 11 from 18/11 and latest kernel here ;)
[Galaxy Ace II Android Development] MarquesYOLO:
The thing is that i only use sdcard1 ( I swap and i have anything on sdcard0) so if i am not wrong the step "- restore or better copy the saved content from sdcard0 @ sdcard1 (because sdcard0 it now only 10MB ! )" is not necesary. isn't it?

Can i follow all the steps you say to me and format sdcard1 from android settings after swap memories? and then copy all saved files again? Any problem of doing like that?
[Galaxy Ace II Android Development] ace2nutzer:
of course! if u've nothing on real sdcard0 .. then just format it in cwm.. and u're done.

But @ sdcard1: That's not right, u should first format and then swap storages... otherwise it's a really chaos. (so format with NO swapped storages!)
[Galaxy Ace II Android Development] ChronoMonochrome:
Where did you find that cluster size of 4096 bytes is optimized for phones? I've read that higher cluster size is for higher read/write speed. Selecting lower cluster you can save some space, but you'll decrease read/write speed.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah i know what u mean.. this is usually right waht u say... i think that is only valid on PC / Laptop .. but for our Phone is best 4096.

I've tested this with A1 SD Bench .. and with high blocksize i've only 10/10mb/s (read-write) and now with 4096 i've 20/13mb/s :)

Type in term. emu. "df" u'll se the wohle Phone, all the partitions are @ 4096 .. the sdcard1 was my only storages with "other" cluster size... :)
[Galaxy Ace II Android Development] MarquesYOLO:
Well, I'm on ART already. But I have a problem, I can't get install WhatsApp, I've tried many ways but is impossible.

Any idea? Thanks

[Galaxy Ace II Android Development] MrBlackCore:
Its a known issue with art and whatsapp, no1 can install it. It has something to do with some whatsapp update. As far as I know older versions of whatsapp work with art. Weird part is... why does anyone use whatsapp anyway?? How is whatsapp better than viber? Viber is lighter, better looking, not owned by facebook and u can call people for free... wtf :D
[Galaxy Ace II Android Development] ace2nutzer:
yeah.. go back to dalvik and install whatsapp.. then do an titanium backup... switch back to ART and restore the whatsapp backup .. and then disable in Playstore the autoupdate function .... but if that also not work.. the u should try to find this Version.. (works with ART): 2.11.432 ;)
[Galaxy Ace II Android Development] shaqman89:
In my case, there were no need for titanium backup.

After I installed whatsapp using dalvik, I just switch back to art and it's still working
[Galaxy Ace II Android Development] ace2nutzer:
@up

then u've now the latest whatsup version for dalvik ??! Can u pls share here your Version ??

I've actually: 2.11.432 but on ART ... Thanks ;)
[Galaxy Ace II Android Development] shaqman89:
Yes, I am. It's the 2.11.505 version.

One noticeable feature is the access from Web (one reason I finally upgraded lol)
[Galaxy Ace II Android Development] Alex_Gamer:
[MENTION=5840412]ace2nutzer[/MENTION] there's no more sd card problem, but i still having the problem on the screenshot when installing certain apps for playstore.
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for Reports ! I'll make later new build with fixed sdcard issue + a little bit more stabilty on CPU OC and maybe more speed + more powersaving if i can found a better I/O Scheduler than SIOPlus :)
[Galaxy Ace II Android Development] gex mordillo:
No problem with the latest version. Only strange thing in the indication of the battery consumption GPS is always active even if it is completely off.

Inviato dal mio... dal mio... Bho!
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!!

Changelog:

20150215:

db8500: display correct voltages also on /debug/ab8500-regulator/status

Increased overall stability (now u can OC CPU a bit more)

Better Battery Lifetime

Changed I/O Scheduler from "SIOPlus" to "Noop"

increased vbbx Voltage to the max for max. stability

Fixed problems with sd / apps / Play

Better Performance
[Galaxy Ace II Android Development] ChronoMonochrome:
Do you have any ideas about that? We know that we need x64 device (or compiler for x86 with support ARM build flags). Maybe we can ask someone to build kernel remotely? As I remember Rox wrote about one guy(don't remember his nick) who can provide build server. Just an idea...
[Galaxy Ace II Android Development] psidco:
0215 still got reboot on 1200,but i think my blackscreen gone no more delay on my lockscreen :D :thumbup: smooth as usual ,thanks sir
[Galaxy Ace II Android Development] ace2nutzer:
This is surely a good idea if we want to test these new things.. and of course do benchmarks to see the difference... theoretically it sounds good... 40% more speed ^^ But to be honest it's actually just on my to-do list... i'll take a look when i've more time for this. ;)

But 1150Mhz stable ??
[Galaxy Ace II Android Development] psidco:
Yes sir,its stable,but i swear i can run [MENTION=1348102]1200[/MENTION] at your previous build before 0130 flawlesly
[Galaxy Ace II Android Development] ace2nutzer:
Hmm that's very weird ... but thanks .. i'll take a look in changelog/github .. to see what i've changed in CPU Table :confused:
[Galaxy Ace II Android Development] Danko Jones:
For me still stable at 1200 MHz. Also faster phone wake up time with newest buildt.
[Galaxy Ace II Android Development] shadowman3333:
In the newest kernel from 15.02.2015 the SMS's doens't work. I had no notification, no messages in SMS applications. I try in standard SMS application and in Textra. I revert 12.02.2015 kernel and SMS's works again.
[Galaxy Ace II Android Development] ace2nutzer:
I don't think the SMS problem is kernel related... but anyway i'll do later or even today an new release...

That will an VERY great release :):o:D;)

So boost it up !!!:cowboy:
[Galaxy Ace II Android Development] Alex_Gamer:
Try doing a fresh installation.
[Galaxy Ace II Android Development] ace2nutzer:
New Build is up !!

Changelog:

20150216:

Enabled "sched_mc_powersavings" again @ "2"

Enabled "wq_power_efficient_default" again

Increased overall stability (now u can OC CPU a bit more)

Better Battery Lifetime

More Speed; more responsive

uploaded all ODIN Versions (codina/p - ext4/f2fs)

I've made this Release since one User reported me some laggs on games and one user meant not very stable like older builds..

Everything should now fixed on this build. :)

Well, that build should be bugfree.. and i hope i can now relaxing me for some days.. but of course i'll continue developing ... together with [MENTION=5695278]ChronoMonochrome[/MENTION]. but what i mean is.. the major things are now really good, performance, responsiveness and powersaving...

But of course.. it's probably always possible to improve the kernel a bit more... however as u can see under "Next Version / To-do" there are really good things, but unfortunately nothing of them is actually done .. due to no time etc..

But to be honest i plan to do this after i've completely optimized kernel size .. in kernel are actually still many things activated... and maybe we don't need all of them.. but we all have already disable much things to make the kernel smaller and faster .. i hope u can feel that! :)

I'll ask here from time to time if somebody need some special features what is actually enabled in kernel.. if no one need that feature then i'll disable it, so that next release result again in a bit smaller code to make the Kernel a bit more faster, (that also gives some kb - mb of free ram ;) )

Well i've already some Questions:

Somebod need,

- TCP ipv6 ???

- all possible tcp algorithm ????

- Various Filesystem formats like ext2, ext3, ntfs etc . ???

Explanation: I think usually TCP ipv6 is not needed when we still using the dafault (old) ipv4 protocoll.

In NT-APP under "Network" we can set the tcp algorithm.. default is "cubic" .. i think that's is good enough.. maybe "westwood" is also good.. and all the other, as u can see there is a lot of various tcp algorithm .. but we only need one :)

@ Filesystems .. maybe u can just post wich Filesystem u all need ???

Well that's enough.. the other things i'll decide itself or when it's easy to understand, then i'll ask u again guys :)
[Galaxy Ace II Android Development] psidco:
Testing new build,im not complain about perfprmance/powersaving,its always awesome sir :D ,am i wrong or ram back to 629 :confused:
[Galaxy Ace II Android Development] miryn:
Yep, already in 02.15 and if i'm not wrong 02.12 version too..

How we gonna live now? :crying:
[Galaxy Ace II Android Development] ace2nutzer:
630mb was available with my first own "reduced kernel size" then i had problems with non working avast firefall.. This was related by disabling printk .. It's dmesg ... After enabling in kernel again printk, ram was back to 629mb..

But as I said, i'm not done with reducing kernel size.

Btw: all ok with latest build? And what about blackscreen on cwm and wakeup for s6d lcd driver??
[Galaxy Ace II Android Development] arroyo:
20150216 F2FS - MADNESS !!

No issues found.

The best kernel since your last kernel (yesterday one).
[Galaxy Ace II Android Development] psidco:
I never get blackscreen on cwn in any of your build sir,the delay on lockscreen gone,more smooth,wait till tomorrow i got random reboot or not :D :thumbup:
[Galaxy Ace II Android Development] beeqb:
Some one tell me the differnt between ext4 and f2fs kenel :confused:
[Galaxy Ace II Android Development] Alex_Gamer:
If u see benchmarks can view the difference, personally I recommend you f2fs because is more smooth, and do repartition.. F2fs takes more space.
[Galaxy Ace II Android Development] shaqman89:
Found no issues so far. And as usual, smooth :)

- Personally, I don't use ipv6 for the moment. So, I'm fine if it is removed.

- Never found a need to change the tcp algorithm :D

- File system I am using should be the defaults one, so I think ext4, f2fs and vfat is the ones that I am using.

Btw, just an idea, maybe a module approach like the one in Chrono's kernel could be used for these items (ipv6, tcp algorithm, and filesystem drivers). If it's feasible, I think it would be a good compromise between richness of feature and size for most people.

Keep up the good work :good::good:

---------- Post added at 04:59 AM ---------- Previous post was at 04:50 AM ----------

I agree. F2FS seems smoother in most cases. And I am using it in my daily drive.

To sum it up, some known difference between f2fs and ext4 should be:

- f2fs has (relatively overall) better performance. Specifically f2fs has (relatively) better throughput compared to ext4

- due to how it stores file, it needs more space

- f2fs is younger, thus adoption is a bit varying, and at (some extremely rare) times entire file system corruption happens. (not all ROMS/kernel have f2fs support)

[Galaxy Ace II Android Development] beeqb:
is this true: i go to cwm,flash kenel then reboot to cwm--->wipe data/cache/davilk--->flash rom cm11+gapps :)
[Galaxy Ace II Android Development] aoh1996:
Flash ROM and gapps, then kernel.
[Galaxy Ace II Android Development] beeqb:
can u show me the steps??? :D
[Galaxy Ace II Android Development] ace2nutzer:
u need first latest Stock JB .. then in recovery install temp. cwm.6028

wipe data

mounts and storages

format system

then CM 11 from 18/11 ext4

power off

boot in cwm

flash pico uni-gapps

flash latest ext4 kernel

reboot system

it's also highly recommended to format sdcard0 and sdcard1 in CM under settings ---> storages
[Galaxy Ace II Android Development] werindam:
[MENTION=5840412]ace2nutzer[/MENTION] I dont need ipv 6. I think anybody dont use it.

What about tcp algorithm.. Hmm i think you need to leave only cubic and delete others.

I use f2fs and vfat.
[Galaxy Ace II Android Development] ddr3gt:
16/02 stable!!

Now with last kernel 16/02 my rom is very very stable with OC CPU 1200 and GPU 690 , i use ART. Thanks!!!
[Galaxy Ace II Android Development] MarquesYOLO:
I'm on f2fs + art for 2-3 days and I feel that the smoothness is bigger with art but also that I have less battery duration. When I was on dalvik the battery lost about 5%/h (about 18h of a full charge). Now is about 10%/h. Is that normal? Thanks.
[Galaxy Ace II Android Development] ace2nutzer:
Nope, with f2fs + art u should have better battery lifetime..

That means some apps or at least one app is not compatible with art or the optimization is not complete.

To boost up the optimization and also to see if some apps are not working with art.. do this:

wipe cache in settings, storages..

shutdown

wipe cache in cwm .. (do not wipe dalvik!)

Then boot, and open all your installed apps, also system apps. if some app won't start --> blackscreen or just white screen, then wait around 5 minutes.. if u've luck it start.. this is only need for the firt run with art ...

just for info: maps, whatsapp, messenger and facebook can take i while.. around 5 minutes.

after that reboot, and open again all apps.. u'll see now the apps are starting faster.

If u've again non starting apps, then delete such apps or go back to dalvik.
[Galaxy Ace II Android Development] DusBekas:
I don't know it's kernel related or not but with 20150210 build I can OC my CPU [MENTION=1348102]1200[/MENTION]MHz, GPU [MENTION=2290141]690[/MENTION], no issue. But with 20150212 when I was using Line and Flutter, phone is unresponsive so I have to reboot with power button. So I decided to lower the CPU and GPU clock to 1150MHz and 690MHz, and the problem's gone. But with the latest build, 20150216, I also had same issue but just with Flutter.
[Galaxy Ace II Android Development] greeceeeee:
Is it necessary to flash new kernel odin? and what about it?
[Galaxy Ace II Android Development] ace2nutzer:
only if u can't enter in recovery !
[Galaxy Ace II Android Development] Alex_Gamer:
If I want to use art its necessary a fresh install? Or it's only recommended?
[Galaxy Ace II Android Development] shaqman89:
Not necessary neither it is recommended.

Just switch to art directly and if you have issues, follow that with cleaning cache.
[Galaxy Ace II Android Development] ace2nutzer:
yeah fresh install not needed for art..
[Galaxy Ace II Android Development] Alex_Gamer:
Okay thanks, i hope all my apps work with that runtime :)
[Galaxy Ace II Android Development] beeqb:
thanks for your guid..but i don't known which "CM 11 from 18/11 ext4" and "flash pico uni-gapps" are....i have cm11 07082014 and gapps kk .....sr for stupid question because i'm newbie :rolleyes:
[Galaxy Ace II Android Development] Alex_Gamer:
Wow... Very awesome performance with art ?
[Galaxy Ace II Android Development] shaqman89:
Do make it a habit to search.

CM 11 from 18/11 ext4 could be found in [MENTION=5840412]ace2nutzer[/MENTION] ftp link given in the first post of this thread, and Pico gapps for kit kat could be found from here

After 24h (flashed cm-11-20141118-UNOFFICIAL-codina_ext4 and the latest kernel with pico gapps) and still no bugs like restarts,black screens and battery lifetime is much bigger :D :D :good:

Any tips for which preferences i have to change to make its performance better?? And i went to cpu options and its governor is interactive at 400-800mhz is it ok or i have to increase it ot 1000mhz?
[Galaxy Ace II Android Development] soko3:
[MENTION=5840412]ace2nutzer[/MENTION] what's new in 20150218 version?

[MENTION=5928539]RetZi4[/MENTION] i reccomend you to set cpu freq 400/1000... i experienced best battery life/performance ratio at that freq... everything over 1000 - more speed, but less battery... and for me even 1000 mhz was enough for hard gaming

about gpu - use stock, you probably don't need more...

one more note

in settings-> developer options

set following:

- window animation scale @ 0.0

- transition animation scale @ 0.0

- animator duration scale @ 0.1 (important for dialer!!)

less animations - more speed and better battery life, up to 10-15%

:)

[Galaxy Ace II Android Development] MrBlackCore:
I also have a huge battery drain.
[Galaxy Ace II Android Development] ace2nutzer:
build 20150218

Changed deepest sleep state from 4 @ 3 (that caused sound glitches by screen on-off.

Changed vbbx from 0x9F @ 0x8F.

Notes: can u guys please test the stability between 0216 and this 0218 build?

Because i really don't know what's more stable and better battery lifetime..

For me i don't see any differences between those two builds.
[Galaxy Ace II Android Development] RetZi4:
I switched my phone from dalvik to art but after restart some apps disappeared.. They are not compatible with art or the wrong part is that i have moved them to memory card before the change?? Should i change it to dalvik again?? :rolleyes:

2. Why u're using 0207 when we've 0216 and now also 0218??

2. Do u think updates are useless??? ?

Info @ all:

On dev-host only builds till 20150216 ...

For builds 20150218 and newer only on ftp-server.
[Galaxy Ace II Android Development] MrBlackCore:
I am using your latest kernel and the battery drain is really huge. Wasnt like that with your previous builds. When I charge my phone to 100% and disconnect it from the charger the battery goes from 100% to 90% in 10 minutes with the screen off and on wifi connection. With your previous builds I had to charge the phone every 36h now I need to charge it every 6-7h
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for report, but u need to write the date of the both builds
[Galaxy Ace II Android Development] MrBlackCore:

Yes, I agree with the others, build 0216, 0218 has huge battery drain.

In 10 minutes I could have lost 10% as after charge and over night (around 8 hrs) I could be losing 5%/hour. In some previous version (I'm sorry I can't remember which), it's only around 2%/hour.
