I'm always wiping data, system, etc., before flashing new rom, I have totally clean CM 11 even without performance controll (only xposed with xposed app settings but no system apps touched with it) for tests.

Unfortunately, problems with receiving incoming calls occurs not often, it happens once for like 5 -10 calls so I cantt find out what is causing it.
[Galaxy Ace II Android Development] kuba130000:
I have blackscreen in recovery. I downloaded emergency kernel, how to install it with Odin?
[Galaxy Ace II Android Development] manthes:
What is the problem with incoming calls?
[Galaxy Ace II Android Development] miryn:
Sometimes when i have a call i cant move the slider to answer it, screen just doesn't respond, i must lock and unlock the phone and then everything is back to normal.

Other problem is when i try to call somebody, the screen goes black and nothing happens- reboot required.
[Galaxy Ace II Android Development] Dr360r:
Perhaps it's a radio undervolting issue caused by some not undervolting suited components.
[Galaxy Ace II Android Development] ace2nutzer:
@ up

Modem is not undervolted at all. ;)

try this 2 things:

1. make sure u're using 50Mhz for WS2401 .. (check sys/kernel/mcde/lcd_clk)

2. Check if DoubleTap2Wake is disabled in NT-APP ... (disable for testing)

3. Also u need latest NT-APP v. 1.6.6.
[Galaxy Ace II Android Development] Dr360r:
I have had DT2W enabled for a while in my phone and i never had issues with making or receiving calls by the way.
[Galaxy Ace II Android Development] miryn:
Like i wrote i have a clear build and all of that options are set just like you've said.

And now something weird.. I'v just downgraded kernel back to 22.11 version (where earlier 2d was pretty nice) and 2D work the same as on the latest kernel- pretty bad (everything the same- without changing mcde freq)

Wtf with this machine...

EDIT: I'v downgraded kernel and of course Novathor to 1.6.5 (wipe cache/dalvik too just 2b clear)

And now bootTime check in Novathor doesn't work.. :silly:
[Galaxy Ace II Android Development] giginski:
yes mee to w8 for new cm11 and then me and my wife will be happy with our phones, hope it gonna be fast :)
[Galaxy Ace II Android Development] ace2nutzer:
yes, but maybe on some phone the dt2w feature makes problem .. this is like the lcd quality ... every phone has different quality... All kernel defaults freqs + voltages are long developed and probed during all the development time .. always according to reports , reboots, and some other stats.. Also from my phone itself..

All that info mixed up ... and that is the default ... i'm also using in my phone kernel default ... even if my phone can handle much smaller voltages ... but this is just to keep things easier and more compatible ;)

Also the difference is not big, between normal UV and extreme UV.

[MENTION=5571055]miryn[/MENTION]

for previous kernel u need v.1.6.6 as well ... read changelog .. there is boottime disabled in kernel .. because of unmounted debugfs .... the boottime feature is unfortunately in debugfs .. so that's the reason for removing it ...

U can also use v.1.65. .. it's same .. just with boottime check.. but using this will FC the App .. because of missing sysfs interface :)
[Galaxy Ace II Android Development] gepel:
Today I make use of GPS (here maps). When I use GPS I turn the screen off. After some minutes of usage the app stopped. Hmm a problem with deep sleep?

EDIT. I m starting to (strong) believe that is an app problem and nothing to do with the kernel or rom. The above problem appears on continuous route recalculations.
[Galaxy Ace II Android Development] manthes:
The combination of this kernel and Liquid smooth didn't work well for my phone. No problems but it isn't smooth. Back to 21/11 which is the best i ever have
[Galaxy Ace II Android Development] ace2nutzer:
did u maybe denied some options (keep awake, etc..) on privacy for maps or so ?
[Galaxy Ace II Android Development] gepel:
No i dont, also i noticed that i have occasionally FC on play store ..
[Galaxy Ace II Android Development] manthes:
Do you have undervolt?
[Galaxy Ace II Android Development] gepel:
No, I don't.
[Galaxy Ace II Android Development] snyfear:
For me the best version since a long time. The 150Mb seems really better size for zRAM. My phone was sometime very laggy with 650Mb and I finally disabled it.

Now everything is perfect!

Thanks for all the efforts you spent for our phone.
[Galaxy Ace II Android Development] kuba130000:
Is there any way to install this Kernel to Lollipop roms?

[MENTION=5840412]ace2nutzer[/MENTION]

Maybe You should create kernel to 5.x.x Lollipop?
[Galaxy Ace II Android Development] Dr360r:
@up

I don't think that L would be the best ROM for the i8160. In fact a KK based ROM would be the best. KK is meant for low memory devices such as the i8160, and now that most newer phones come with at least 1 GB of DDR3 (faster than the Ace 2's DDR2) 629 MB RAM is pretty low and perhaps it's better to stick to KK.
[Galaxy Ace II Android Development] kuba130000:
Yea.

But.. We have some good LP roms.

LP rom with this kernel maybe will be very good.

[Galaxy Ace II Android Development] gepel:
[MENTION=5840412]ace2nutzer[/MENTION]. If I don't want to mess with swap storages, overclock, undervolt etc, do I need the novathor app or not and why ?
[Galaxy Ace II Android Development] ace2nutzer:
yes u're right ! btw ace2 has 768MB RAM ... .. and KK ROM can even run on 512MB Devices.

As for L ROMs.. i don't know how much RAM it needs .. but for sure more than KK.

Actually i don't see any reason to use L ROM instead KK .. simply because i don't miss nothing on KK .. and all my needed Apps works with KK.

hmm u can also run this kernel without NT-APP at all ... but i suggest to use NT-APP .. it's better .. because u can regulate it perfect... for example powersaving feature for Wifi + Audio.

As for OC: just use MaliAuto Boost .. with defaults.. and for UV: just let CPU + GPU @ 0.0mV ... this is Kernel + App default ... means no OC + UV at all ... it runs with kernel default... it then same like not using the NT-APP at all.

I just can only suggest to use always latest kernel with latest Settings app.. to have best performance, stability and battery lifetime.
[Galaxy Ace II Android Development] manthes:
Actually i don't see any reason to use KK instead of 10.1 roms except colorful emoji :o:p:p:p. 10.1 is lighter and i have flash player with every browser i want.

But i really like color emoji and also liquid smooth which doesn't have any build for 10.1
[Galaxy Ace II Android Development] Culateralligator:
I've been trying for a couple days Liquidsmooth and it's amazing how fast it runs with Ace2Nutzer kernel. It's a pity this ROM is not supported any more, cause it has not very important bugs, but a lot.
[Galaxy Ace II Android Development] ace2nutzer:
New Kernel is Up !!

Changelog:

20151130:

Enabled almost all Cryptographic Options

Various Fixes

Better Performance and Battery Lifetime

More Smooth

Clean Build

Use it only with NovaThor Settings v1.6.6

(Download on FTP Server)

Have Fun ! :o
[Galaxy Ace II Android Development] ace2nutzer:
Damn i need to update updater-script in order to set automatically right permissions to init.d scripts.

So u all need to set right permission manually actually ;)
[Galaxy Ace II Android Development] jordirpz:
Delete,sorry
[Galaxy Ace II Android Development] miryn:
Our machine should be really smooth now after that all "more smooth" in changelogs ;)

As always thx for new kernel, appreciate it, but you should add a note like 'more smooth for s6d', cuz on WS it's still worse than few versions back.
[Galaxy Ace II Android Development] ace2nutzer:
yes and no... that "more smooth" is always valid for both LCD Drivers. But of course actually only s6d is 100% smooth ... ws24 is still crappy but it has nothing to do with kernel itself probably .. also not the LCD Driver itself .. even if it can change the behaviour a bit .. but anyway changing Values like hell and it'll anyway never great like on s6d because i suspect it's more a problem with the GPU Driver from the ROM itself .. (what i actually never touched .. and also i don't can) But hopefully it'll be better with new CM 11 .. if not i can try to find better Driver. And even this, is almost impossible for me, because i don't have WS2401 anymore ... so i can't test it :)

I hope u've understand now what is the main problem .. .. it's not simply changing lcd freq and that's it !
[Galaxy Ace II Android Development] Dr360r:
In my case, compared to an Asus Fonepad i've recently bought, exploring maps in the latest Google Maps isn't so smooth (with stock JB it could get definitely jerky but the panning is still "rough" even with all the optimizations), while the status bar is, when pulled up and down. Don't know whether maps is smoother or not on S6D, but the difference is there if you compare it with a tablet.
[Galaxy Ace II Android Development] snyfear:
Here some questions I'd like to be answered in order to satisfy my curiosity :

1° Is somebody tried to enable Android encryption on our devices?

2° If yes, did you noticed any performance reduction?

3° Is it still easy to flash new CM11 build (if any) and new kernel update when encryption is enabled?

4° And what about accessing the internal memory via USB?

Thanks in advance,
[Galaxy Ace II Android Development] greeceeeee:
On latest kernel zram seems to be disabled after flashing it...
[Galaxy Ace II Android Development] Dr360r:
Anyways i enabled Force GPU rendering in Developer Options and maps in Google Maps seem to be faster to pan around.
[Galaxy Ace II Android Development] gepel:
You have to change the file permissions of etc/init_d/zram_01 to 755 or wait a new version of kernel from ace2nutzer.
[Galaxy Ace II Android Development] Dr360r:
@Up

Perhaps you meant to quote greeceeeee?
[Galaxy Ace II Android Development] gepel:
Correct !
[Galaxy Ace II Android Development] Dr360r:
755 or, in other words, RWX, RX and RX from top to down.
[Galaxy Ace II Android Development] heldix:
Great kernel. Very smooth fast reactions best multitasking. only thing i dont understand is the low 3d performance on my device (not new in this kernel have this since some months ago). I have stock kernel settings, didnt touch anything.

[MENTION=4887026]greeceeeee[/MENTION] ZRam is 88MB for me.
[Galaxy Ace II Android Development] ace2nutzer:
Okay thx for report.. I'll check 3d performance soon when i'm done with rom building.

Btw default zram size is 75mb x 2 = 150mb.

Why 2 block devices ? - one device will only cause load for one cpu core... That caused unbalanced cpu load. With 2 devices the load is equal on both cores... Even if only 1mb zram is used ;)
[Galaxy Ace II Android Development] Dr360r:
Clever. Wonder if the RAM previously worked that way too, before you enabled zRAM.
[Galaxy Ace II Android Development] ace2nutzer:
It worked all the time with only one device....

Why ? Most of linux / Android defaults are just optimized and pre-configured for single core + Server.

Same Problem is on Microsoft Windows.
[Galaxy Ace II Android Development] Dr360r:
Even for flagship octa-cores and the like?
[Galaxy Ace II Android Development] ace2nutzer:
Yes and even more painfully because there is cpu hotplug enabled. All 8cores are almost never used at the same time.

Here on ace 2 we had also hot plugging.. That caused lags and sound scratching during screen on and off... Especially with screen off + music streaming over wifi... One core was not enough to handle so many threads at the same time.
[Galaxy Ace II Android Development] Dr360r:
Perhaps what was meant to keep the battery from draining too much just backfired.
[Galaxy Ace II Android Development] ace2nutzer:
Btw the 2 devices for zram is only for zram.

Ram itself don't have this Problem.

The balanced load for everything is already regulated with this sysfs:

/sys/devices/system/cpu/sched_mc_power_savings by keeping the kernel default of "0".
[Galaxy Ace II Android Development] ace2nutzer:
Yes of course.. But in reality it drains more power.. Because of more cpu load with resulting higher cpu voltage.

Some manufacture actually have disabled the cpu hotplug on brand new phones.. Just because it serves nothing.
[Galaxy Ace II Android Development] PolishVodka:
To delete.
[Galaxy Ace II Android Development] manthes:
I am the only one who believe that all kernels after 21/11 are worst?

Sorry ace2nutzer but if i am right maybe it is better to take this build as a base and make improvements :confused:
[Galaxy Ace II Android Development] ace2nutzer:
Hey Manthes !

thx for reporting.

I've checked all changes .. after21/11 Commit ... and i don't see anything wrong what can destroy performance.

Check commits here:

https://github.com/ace2nutzer/Samsung_STE_Kernel/commits/3.0.101

start checking with 22/11 Commit:

https://github.com/ace2nutzer/Samsung_STE_Kernel/commit/9293ef4798a82641e0c85d719ec021ddee3a43d1

Maybe someone can find the problem ?
[Galaxy Ace II Android Development] manthes:
Maybe it is just a combination of liquid smooth and my (very) strange lcd as you know. So it was a simple report from me and because i don't see any other reports for latest kernels

And something else. With latest kernel nova launcher was redrawing some times
[Galaxy Ace II Android Development] ace2nutzer:
Ok, just lets wait for next build.. I need to recalibrate minfree values.
[Galaxy Ace II Android Development] ace2nutzer:

Very good work! 3D is back at the performance it should be. The last puzzle item fixed XD. I still got a Swap-Partition with a size of 80MB. I never installed custom init.d scripts or anything else. But ill stick with it i guess.

Thank you!
[Galaxy Ace II Android Development] gepel:
Delete manual all init_d files and reinstall the kernel. Should be OK now.

[MENTION=1336074]Ace2k[/MENTION]ernel, Great work man. Thank you.
[Galaxy Ace II Android Development] lab34:
Wow ! Big thanks for this version !

It runs so nice. It flies now. :)
[Galaxy Ace II Android Development] Sylvinette:
3D games runs so smooth!

If I charging using usb cable, my phone is going hot, is it normal?
[Galaxy Ace II Android Development] Dr360r:
Getting smoother and smoother with every new kernel you compile. I reverted zRAM SIZE back to 75.
[Galaxy Ace II Android Development] damian12332146:
New build works perfectly! Only the final version of CM and I will be on cloud nine. ^^

I have a question. Do you have 480p quality in YouTube app? I can watch clips only in 144p and 360p. On stock JB and LP (for example Chrono's Omni) it worked fine. How can I get 480p option?
[Galaxy Ace II Android Development] giginski:
thx for great work, but i think all ppl w8 for new CM version of Your rom, pls tell us when can we expect it>?
[Galaxy Ace II Android Development] MrMateczko:
Nice work on the new kernel, GTA: VC now performs almost perfectly with smooth 30FPS! GTA: SA also works fine, though sometimes there are weird stuff popping out once in a while, which don't appear in Chrono Kernel, what tweaks to GPU you recommend?
[Galaxy Ace II Android Development] manthes:
With zram to 0 i had fc's with quick pic and Google services. Also nova launcher was redrawing all the time. After changed to 300mb it looks ok
[Galaxy Ace II Android Development] Dr360r:
What Nova version are you running? I'm running 4.2.0 Prime, SIZE=75 and it doesn't redraw.
[Galaxy Ace II Android Development] manthes:
4.2.0 the free version and zram was zero. With 300mb it is ok until now
[Galaxy Ace II Android Development] gepel:
I am running in default zram 0 and everything is super smooth without any redraw.
[Galaxy Ace II Android Development] greeceeeee:
Is it really smooth without zram??
[Galaxy Ace II Android Development] ace2nutzer:
Thanks Guys for all reports and so on :)

U're great Community ... it's like Having some extra Family or friends :o

@ zRam

This Kernel is already compiled for new ROM ... probably for new ROM zRam is not needed at all if everything goes well. But using this latest kernel with older ROM's actually better to use SIZE=75 .. which gives 150MB zRam.

Use zRam as low as possible ... it's like Salt ;) The more zRam Size, the more Real Ram is wasted .. and more unneeded Overhead ... ;)

@ CM11

I really can't say an Date when it's finished.. but be sure that i'm giving my best.

So actually i'm still working on it.

The fact is: compiling kernel and releasing it is much easier and faster .than making a new ROM.

But i think next update is then for the ROM, .... kernel is now almost fully optimized.

I'll try to release this Year ... but anyway i can't promise that... so pls don't kill me :)

If it's not this Year --- then for sure in January :)
[Galaxy Ace II Android Development] DetroX:
How to discable end of charge backlight notification? Any ideas? Maybe add it to NT app ? :D
[Galaxy Ace II Android Development] Culateralligator:
Thanks for all those efforts!

I don't play games at all. I use Internet browser with this mobile as it was a PC.

So, please, give us a fast one!

I normally use AOSP J-Team and sometimes (like now) Vanir. I had problems with Vanir and last kernel (blinking red square @ perimeter of screen). I restoored backup, flashed 13/12 kernel again & it disappeared.

BTW, I'm not using zRam by now & everything's working fine.
[Galaxy Ace II Android Development] Dr360r:
A great developer calls for a great community.

In fact i was about to say that it never does any good to urge a developer to release something.
[Galaxy Ace II Android Development] Oğuzhan1907:
How activate zram ?
[Galaxy Ace II Android Development] DetroX:
In system/etc/init.d and open 01_zram for instructions
[Galaxy Ace II Android Development] lab34:
Hi. Today I had a few redraw on holo launcher, and a few temporary black screen... So I reactivate zram and I will see if it's better...
[Galaxy Ace II Android Development] ace2nutzer:
for ppl that don't know that:

after editing 01_zram script u've to reboot the Phone .. or just execute the script with SManager App as root.
[Galaxy Ace II Android Development] greeceeeee:
Actually the same for me with activated zram,i think the problem is the rom not the kernel....It had also fast reboot 1-2 times
[Galaxy Ace II Android Development] psidco:
Hi again all,in latest 2 build that i flash (now im use latest for sure) i notice that nova launcher always redrawing(i mean its blank when we open app drawer for a few second) like when im play video from mx player n go home / when closing coc n go home,is that normal?
[Galaxy Ace II Android Development] ace2nutzer:
check if zram is activated ... type: "free" in term. emu.

u should see: swap: 153000 approx
[Galaxy Ace II Android Development] psidco:
Oh i forget,i set it to 0,bcoz i think that its drain my baterai ,so its just about zram right?
[Galaxy Ace II Android Development] ace2nutzer:
Yes, actually without zram the Phone is not working properly... but i hope that zram is not needed anymore with new ROM.
[Galaxy Ace II Android Development] RyxeL:
I can't download NT-App from dev-host using chrome. can you mirror it
[Galaxy Ace II Android Development] Culateralligator:
It depends on the way you use the phone and if you don't mind having eventually a FC. Generally speaking, last kernel without zRam gives me no problems.

I don't have heavy apps and I've suffered a pair of FC since installed last kernel.

If it becomes annoying I'll finally activate zRam, but I prefer for now a bit better performance even at the cost of one FC per day.
[Galaxy Ace II Android Development] ace2nutzer:
same here .. sometimes my live stream radio app: BigFM .. is just FC even if nothing is running in background .. and even if i don't touch the phone at all ... with activated zram this doesn't happen.
[Galaxy Ace II Android Development] ace2nutzer:
Check Charging Current on NT-APP ... make sure to don't use more than 700mA for the 1500mA Battery.

Those higher current steps are intended for 1700 - 3200mA Batteries.

As help, if somebody don't know which current is right for the actually battery .. just use battery capacity /2 = charging current.

Example:

for orig. battery 1500mA:

1500 / 2 = 750mA ...

so 700mA is right choose ... but 800mA is OK too, but original charger specification is 700mA, so we use 700mA by default.

If somebody really need higher current for bigger battery.. then u should use proper higher USB Charger ...

But i can tell u for sure: Cheap USB Charger for 2 € from ebay which is called for 1A --> 1000mA .. can't even provide 500mA ;)

I've here high quality 700mA USB Charger .. and it can provide 700mA without problems. - So don't buy fake parts guys ;)
[Galaxy Ace II Android Development] gepel:
I don't have any fc until now ( I had some in previous build with zram on), so I prefer using the phone without zram.
[Galaxy Ace II Android Development] ace2nutzer:
btw i mean with FC that the lowmemorykiller kills the app .. but without appearing a drop box like: "Nova Laucher is now force closed OK"

Because there is a little difference ... really FC with drop Box = instability .... (Hardware malfunction, too much overclocked, to low cpu/gpu Voltages)

I am using latest kernel 121315 with zram SIZE=75.

I had some issues to report:

1. Some reboots while using Wifi Hotspot Sharing.

2. Applications like Waze silently closing.

Just note that:

I refused Google Play services to awake my ace2 via Privacy Guard.

I used DisableServices to disable SystemUpdateService for "Google Play Services" and "Google Services Framework" in order to reduce battery drain.
[Galaxy Ace II Android Development] ace2nutzer:
Try SIZE=100

@ reboots ... only on 13/12 ??

What about CPU/GPU UV/OC and with which CM Performance Profile is this happen ?
[Galaxy Ace II Android Development] lab34:
Hi, I'm using 100 for zram since two days and it's better. No more fc on some app (tinfoil for twitter for example)
[Galaxy Ace II Android Development] ace2nutzer:
instead to increase zram size u can also try to remove some unneeded apps ...

Actually i'm using my phone with no zram with no FC since i've removed the APP TASKER ... apparently that app was using much RAM...

But as i said, maybe with new rom + removing some apps, nobody will need zram anymore...

btw: in the maintime u can do this already ;)
