Yes 4.4.4 is best for low-ram devices. Also there is no point on using anything newer than 4.4.4. All Apps i need works on 4.4.4.

Also 4.4.4. is still supported by CM .. (Security updates and so on .. ) So really no reason :)

That's true: No DDR OC and no FIOPS I/O Scheduler here.

I've to admit that FIOPS is slightly faster than SIOPLUS .. according to an benchmark found on the internet.

But to make it working it's needed to update the Filesystem Layer to an newer Android-kernel Base .. and this is a bit tricky as i don't want to mess it up with

such very sensitive Sources .. once there is a small issue .. u can forget about stability, also it'll destroy with time all your Data .. if there is something not properly programmed. so i'll stay away to risk this for an minimal improvement.

As for DDR OC: As i many times already said: it's still experimental and it does not OC only the RAM (DDR) .. but it'll OC the half phone without to know what consequences it'll have .... that means it overclocks also things that does not improve the performance at all but because they will overclock as well .. logically they will drain more battery without having some benefit. Of course the part of DDR OC increases performance .. but IMO it's not worth to use it.

If one day we've properly DDR OC, then i'll implement it for sure :)

If you have partitioned to have max data

then MM runs double faster than kitkat

And games run double faster than cm 11 in cm12.1

in cm 13 it will set records

[Galaxy Ace II Android Development] IAmLucky:
kitkat will still be probably better. Because UI is very light aswell has more free ram. It will take a lot of time to make MM final build. While kitkat exists long time already.

Ace2nutzer sir will your upcoming cm 11 will run gta sa at full speed without need to overclock?
[Galaxy Ace II Android Development] ace2nutzer:
Sorry but how i should i know this ?

u're asking for an non existent ROM + Kernel :)
[Galaxy Ace II Android Development] saimyounas786:
What i am asking is will your upcoming non existent rom + non existent kernel will double the performance with existent rom + kernel?
[Galaxy Ace II Android Development] ace2nutzer:
lol !! :D

U're again asking an impossible thing xD

Nobody can say if an future ROM will have 2 times or 3 times or even worse performance ... we've to wait and test when it's done and there.

But maybe u just want to say if it'll run better or worse ??

I can guarantee that it'll work better for sure .... bot how much better is really difficult to say..

However in other words: it'll work at maximum speed possible .. and it'll use all available hardware featured accelerated things...

In smaller words: 100% Performance.

Additional info:

The Total Performance is coming from:

Hardware, CPU. GPU ...----> (u can't change it, but u can overclock it)

ROM (means software improvements .. u can optimize this)

Kernel (same like ROM)

CPU features like NEON, FPU etc ... (u can't change them .. but ROM + Kernel decides what will be used .. and how ..)

Last part is very important and eats actually much performance as it needs (actually) to run in soft-mode .. instead hard-mode

U can understand this like : hardware support or software emulation ... sounds painfully ?? - Yes it's ...

New ROM + Kernel will try to use as much as possible hardware NEON + FPU ....

Just only this will improve the performance .. without to mention any countless of other optimizations ;)

Hi from Germany,

quick question, as I have to install this ROM on a friend of mines phone:

Use build 160201 or 160209 right now?

My initial idea was 160201, as she doesn't need the sound optimizations and changelog of 160209 shows there were no bugs to be fixed in 160201 -> really bugless.

Thanx in advance

René

PS: No, I cannot wait for the next release. ;)

EDIT: Any special reason trebauchet launcher isn't included in your CM11? Missing the ability to hide apps without paying for that...
[Galaxy Ace II Android Development] IAmLucky:
over clock CPU at 1200 mhz is just a must... 800 MHz makes phone totally garbage lol
[Galaxy Ace II Android Development] ace2nutzer:
U can use latest build. Why it's not better to have better Sounds ? ;)

Trebuchet is still buggy .. even with latest CM Sources .. (tested ;) )

what does 128 KB SD card speed feature means? I'm just wondering what do you mean.
[Galaxy Ace II Android Development] Dr360r:
And it can break your SD card too. I tinkered with it and a 8GB card from a reliable brand turned RO half a year after right when i badly needed to take a picture of something.

[MENTION=5840412]ace2nutzer[/MENTION] : Does the swap storage is still enabled by default?

I mean, I did not enabled this setting. I have some apps installed in the phone internal storage and in internal SD card.

So should I proceed as follow avoid any problems with Apps and Apps data?

- wipe data of NT settings

- wipe cache via CWM

- install latest kernel zip via CWM

- install NT settings 1.7.1 zip via CWM

- reboot

Thanks for your help.
[Galaxy Ace II Android Development] ace2nutzer:
@up

this is correct !

But swap storages + DT2W is disabled by default over Nt-APP.

Only DT2W is enabled by default if there is no NT-APP installed at all :)
[Galaxy Ace II Android Development] Dr360r:
It basically makes sdcard0 (internal storage) become sdcard1 (external storage) and sdcard1 become sdcard0 once the system is loaded (in cwm sdcard0 will always be sdcard0 and the same for sdcard1), it doesn't act in any way on /data. If you have any apps on internal storage and enable swap storages, you'll be able to use them again when you disable swap storages.
[Galaxy Ace II Android Development] Matteo90:
That's what you mean by 128kb sd speed? If so, according to the article you should increase the chache size to 1024 or 2048, not decrease to 128...
[Galaxy Ace II Android Development] IAmLucky:
oh, I think I found that he means. He means I/O readahead kb for external storage. Possible to do for internal storage. I haven't touched that idk. Found in chrono kernel settings. In KitKat it should be in nova thor settings or which app it uses for tweaks.
[Galaxy Ace II Android Development] Dr360r:
I say i tweaked that readahead stuff on a new 8GB card also used to link apps, but after 6 months i went out and had to desperately photograph something. It didn't display any error message but later i found only blank images. I switched cam to internal storage but it was too late. Had to replace external sd card.
[Galaxy Ace II Android Development] ace2nutzer:
@up

it was just a case. It's not possible to damage the sdcard by simply changing readahead size.

It's even no matter of preference .. it'S more over related on how the filesystem works, how it's configured, how big is the cluster size and so on ...

According to those hard-coded Values u can choose an appropriate read kb size ...

It's even optimized for everything: sdcard0, sdcard1, internal Storage, and other Ram related filesystems acting as temp filesystem in RAM.

Of course every Volume uses is own size.

But anyway, changing this Size to an non-optimal size can improve the read speed in some rare cases like:

u have to copy 1000 Files... each of them has exactly 1024kb ....

so using readahead kb of 1024 will optimize the speed for copyng such files.

But because every File has different Size, it's best to use hardware block-size .. for read ahe... as it'll usually ready block by block without need to fragment or split the files.

Stock Value was 256kb i believe .. and there is a reason to keep this Value small ... so using 512kb is already +100% .. i really can't understand such articles that suggests to use even 2048kb ... i've many times tested I/O Speed with an benchmark and 512kb was always the best decision.
[Galaxy Ace II Android Development] rockeetman:
I'd rather say: please don't add any new features. I guess new ROM release will give this phone a new life anyway. But you won't finish it, unless at some point you say stop and just stick to what you have. Every new thing modified in new ROM may cause issues, then require time to debug. I personally think, it's better to have fully stable kernel and ROM than have it bundled with all mods found on the internet, but one year later ;-D So, [MENTION=5840412]ace2nutzer[/MENTION], thanks for your great job, I'm waiting for more ;)
[Galaxy Ace II Android Development] ace2nutzer:
yes exactly my opinion .. i'm just tired to test new things.

i'm just updating, debugging, and optimizing .. nothing more :)
[Galaxy Ace II Android Development] Culateralligator:
Two small suggestions, ace:

- Power save profile is really effective... But it makes almost unusable the phone. Would it be possible to increase CPU maximum frequency to 600 MHZ? Or anything that makes a bit less slow the phone.

- When battery is completely charged, leds, mainly at night, stands on lots of hours. Is there a way to automatically switch them off, after 30/45/60 minutes it's fully charged, f.e.?
[Galaxy Ace II Android Development] ace2nutzer:
Yes, next release will have 600Mhz for Powersave .. that's a good Idea, it'll even reduce power consumption on IDLE when using "Balanced" or "Performance" :)

Hmm sure, but i'm just too lazy to do that :) There is really no point to turn them off ... if the lights is disturbing .. just put the phone on the display side instead of battery side .. then u'll not notice. Also they can't overheat .. u can let they on even for ever .. nothing will happen .. except that it's not really cool for the lithium battery to stay for long time fully charged ;)
[Galaxy Ace II Android Development] Dr360r:
I prefer to never ever leave electrical appliances on (including charging phones) while sleeping.

[Galaxy Ace II Android Development] Culateralligator:

It's a feature of Ace2Nutzer's kernel.

maybe [MENTION=5701712]shaqman89[/MENTION] (he is testing my builds.... big boss of build-server ;) ) can write what is not working on latest builds for the Guys here.. Thanks.

Clean installation:

make cwm backup

backup of sdcard0 (internal card) (over computer)

wipe data

unmount everything

format sdcard0 -->vfat

format system

mount system + cache

flash ROM

flash kernel

flash NT-APP

reboot system

after the first boot, power off the phone

and boot to recovery again

flash gapps

choose reboot system

say yes to root the system.

Great job [MENTION=5840412]ace2nutzer[/MENTION] :good: :good:

I found most (if not everything) basic are working. This includes, WiFi tethering, RIL, camera, etc. So, it should only have some minor app related issues.

After testing it for almost a day on a few apps (roughly 30), here are the issues I found:

Instagram can't use login to facebook, it starts to open a floating webview, but then stucks with the loading.

GPS still has pinpointing location issues. It works for coarse location, but fine location still has issues.

Turn by turn location crashes and FC maps instantly.

Twitch could open some feed video, but not some other. Rotating live videos doesn't trigger FC though :).

Other than that, everything is working and I do get the impression that switching between apps (a.k.a multitasking) is faster.

Just in case someone is wondering related to previous discussion, I don't have standard partition layout. But with gapps, I still have 55.39 MB free on a 611 MB system partition.

So you may need to adjust the size of your system partition if you have less than 600 MB.

Thanks for report !

Hmm really strange.. ! On 18/11 (ROM) with full f2fs everything work fine !

And the ROM have exactly the same kernel (19/11) ! therefore i really don't know what i now wrong :(

EDIT1: Right now tested and works 100%: Wifi, reboot to recovery + Download mode from android Power Menü. (on 18/11 ROM F2FS codinap)

now, I'll test the F2FS Kernel for codinap .....

EDIT2: Tested same things on F2FS Kernel 19/11.. everything OK !

EDIT3: Downloaded it from Dev-host: OK

EDIT4: Download from FTP Server: OK

Check your kernel installer script and make sure that system mounts not as ext4.

Hello if I install your last rom, the ext4 or the f2fs, I don't need to install the kernel after?

Thanks for your work
[Galaxy Ace II Android Development] :
I have question, [MENTION=5840412]ace2nutzer[/MENTION]. Your newest version of ROM all the time based on TC CM11 from 07.08.2014 or other CM11 version? Or maybe you build latest CM11 based on source from 18.11.2014? :D
[Galaxy Ace II Android Development] r_e_n_e:
Is there any detailed instruction manual how to change kernel from non f2fs (ext4) kernel to f2fs?

Is it necessary to upgrade CWM version?

Where is the latest one for Ace2?

Thanks for help.
[Galaxy Ace II Android Development] ace2nutzer:
So you Guys :)

First of all, I've removed the F2FS Kernels from both Servers.. and I've re-upload the same kernels but with corrected updater-script !

Now Wifi etc. works ! ;) Also NT-APP can be used without Risk of instability :)

about the CM 11 Build:

It's based on latest TC Build 20141109... Changelog from me:

- Camera Fix - Thanks [MENTION=5717704]DJ.Kurrare[/MENTION]

- init.d fix (sleep 90 command in sysinit)

- ADB Fix - Thanks [MENTION=4962787]fluffi444[/MENTION]

- Added Nova Launcher (better and smoother)

- My Kernel from 20141119

- Live Video + YouTube already fixed from Meticulus.

U'll find 2 Versions.. one for ext4 and one for full F2FS... both Versions.. all the same Fixes and Kernel...

So now we can call this Build really "Bugfree" and probably nearly "Final"

The only Thing to do:

Just follow my Kernel Updates for more stability (CPU Voltages, LiveOPP improvements, algorithm etc) and optimized CPU Gov. for more Smooth and optimal CPU / Battery Usage.

I'll write Instruction .. on Post #3

Yeah.. take a look on Post #2 about Bugs.. it's nothing new .... I'll fix this as soon as possible. - About stability ... thanks for report... I'll check CPU Voltages... so next Build (kernel) should be more stable for all.

I'll write this on Post #3

But it has nothing to do with Kernel itself.. it's just different Filesystem.

cwm Version upgrade automatically.. if may be you have disabled recovery updates from developer options menu.

Latest Version.. just take a look in the Thread Title here.. or simply on Dev-host .. u'll see the newest Build with newest Date...

I've writed Instructions in Post #3 how to install F2FS ROM / Kernel and how to repartitioning the MMC NAND-flash to have more Space on /data and /system to use successfully F2FS and even with ART... because both needs much more space on /system and /data !!

Therefore, first Repart., and then install F2FS ROM !

I think all the time it has something to do with the fixes from [MENTION=3329816]mkaluza[/MENTION] .. because that happens since his fixes for fix. min. freq etc.. where implemented on TC Sources. I really don't know about this fixes.. because before this fixes.. the min. freq was 100% OK..

Revelation!

Shaq the Man, what kind of issues on GPS? The last final build 150714 still has the same issue with GPS?
[Galaxy Ace II Android Development] shaqman89:
It's a new issue on the latest 20160217 build. Like [MENTION=5840412]ace2nutzer[/MENTION] says, it's a test build, so it's not yet the final build.

GPS works Okay for showing and retrieving our location (so in maps the blue dot shows our spot) but it can't lock on it yet. So, apps like GPS test, or turn by turn maps don't work. So if it's just for geotagging or check in to a spot, it works. But for more detailed stuff, it currently have issues.
[Galaxy Ace II Android Development] Dr360r:
Try checking the gps.conf . Actually, i'm installing it, always keeping the cwm backup at hand of course.
[Galaxy Ace II Android Development] shaqman89:
It didn't occur to me to check on this. I'll give it a try.

But there was some errors to related to GPS in the logcat. Seems like gms not succeeding in saving location states, but editing the gps.conf should be worth a try.
[Galaxy Ace II Android Development] Dr360r:
Otherwise, try latest pico gapps off of Opengapps.org. It says GMS and gapps also install a gmscore thing.

I remember posting my take at getting an optimized (faster lock due to fewer lines) gps.conf
[Galaxy Ace II Android Development] shaqman89:
Negative. Adjusting gps.conf did not help here in my case.

And I believe the one in ace2nutzer ftp is already pico from Opengapps.org. I checked in gmscore is there.

I haven't tried with the latest though.
[Galaxy Ace II Android Development] ace2nutzer:
Yes .. it's the same build ... but u can get newer gapps over opengapps.org ...

But it shouldn't change too much .. since it's probably an issue with applied Patches or wrong Java Version.

We'll see what will happen on next builds...

Forgot to mention:

Google Play Services FC issue is fixed

Issue with deep sleep is also fixed
[Galaxy Ace II Android Development] Dr360r:
By the way i see that gps.conf is bloated. I'm trying with my "deflated" one and report how it works.

[MENTION=5840412]ace2nutzer[/MENTION]: finally! Now phone will last even longer. I don't care if gps works or not for now (i have a PND for my car).

---------- Post added at 02:51 PM ---------- Previous post was at 02:13 PM ----------

Well, in my case on new ROM GPS is working, and it finds location in a pretty fast fashion.
[Galaxy Ace II Android Development] ace2nutzer:
lol !! Really ??

With edited gps.conf or with stock gps.conf ???

Can u please try both Variants ??? - Thx !
