I didn't said you said it :D

I'm saying that it's pointless to optimize that frequencies because it's already draining battery a lot.. Leave those voltages on Rox's stock values, so it will work on 95% of devices

Okay, you are kernel maker, you do what you think you should... About lower freq step (for example 200 MHz) it's just advice from hardware engineer, but final choice is yours ;)

For me, phone is working on 200 mhz without jumping to higher (and i'm listening to music always, and checked everything)

I just suggest to give users choice:

200, 400, 600, 800, 1000 MHz and over 1000 whatever freqs you want... (i suggest TC stock freqs and voltages, no sense to optimize voltages for it)

Otherwise, everything is perfect, and with all those steps, i think i will flash newest kernel and it will be ultimate ace 2 kernel ;)
[Galaxy Ace II Android Development] ace2nutzer:
I think u all already forget that till now most stable voltages.. are founded out by me...:

look from TC CM11 Changelog:

But don't worry.. wait for next build.. the steps are definitely good.. at this way.. (i know what i do) but if anyone like to have anyway 200Mhz or even 100Mhz for min. freq.. i'll show u Guys how to do this with init.d scripts.. also how to change the varm and vbbx Voltages .. :o But usually in next build not needed because i'll optimize Voltages for max. powersave on low freqs.. and highest voltages on high freqs for max. stability on OC over 1Ghz .. that's it ! ;)
[Galaxy Ace II Android Development] ChronoMonochrome:
Yeah, I also admit that TCs voltage table works stable for most users. I'm aware that it actually undervolted table from [MENTION=4832589]cocafe[/MENTION], but somehow it works stably than even AVS-based voltage :) As far as I remember, in past vbbx=0x8f (or 0x9f, whatever it called - +-400 mV) cause reboots when it's used for CPU freq < 800 MHz. I think, body biasing voltage isn't holy grail, so its overvolting more than by 200 mV from orig. voltage cause reboots.

UPD. ah, okay, in latest source here used vbbx=0xdb for non-OC freqs. Maybe main problem is in varm=0x3f ?
[Galaxy Ace II Android Development] soko3:
Don't know if this is helpful, but on rox's rom from august, and older roms, I undervolted cpu in NT app for -87.5 mV and it worked stable on every frequency(even 1250 MHz)

[MENTION=5840412]ace2nutzer[/MENTION] , you are missing point again...

TC stock voltages are yours, ok, congratulations, thank you, HUGE THANKS FROM ALL

I just said: those are the most stable voltages i know

If high freqs are making problem for 3 months, hey, bro, set it back to stock. Simply...

We have those high freqs, but can't use them...

If you have a d**k, but it can't get hard to do 'job', it's like you don't have it... ;)
[Galaxy Ace II Android Development] ChronoMonochrome:
Yeah, I tried it few months ago and it didn't helped.

Don't know if it's might help with OC, but seems that phone works stably when all arm_steps uses same vbbx, that maxed out.

I currently testing this liveopp table (250-1230 MHz with screen on, 200 MHz static clock with screen off) and so far it works stable even with extreme GPU/DDR OC. As I said, it probably won't work on phones, that has too low AVS vbbx voltage (in my case vbbx=0xeb - vbbn=+300 mV, vbbp=-200 mV). However I can't said that it's good in daily usage - for more powersaving it's better to leave vbbx=0xdb for non-OC steps...
[Galaxy Ace II Android Development] ace2nutzer:
Yeah i know what u mean.. but it's not so simply as u think.. the difference between the TC Stock kernels and actually ace2nutzer and chrono kernel, is not only different CPU Voltages.. but also new / completely different LiveOPP OC Driver, new logic, new Algorithm.. new GPU OC Algorithm and and and....

Be sure that i and Chrono are working really hard to improve stability.. it needs only some time for testing....

But i'm sure at the end it'll work better than your old Builds / kernels what u mean.. it's all outdated and not optimal, not smooth and max. OC is lower than actually kernels here.. so pls give up to forcing me to make impossible things.

I also don't need an medal for this all... And sorry for this, but i believe i need to say this again and again:

The Rules:

§ 1. This is my Custom Kernel.. and i like to share it with you...

§ 2. The Source Code is open Source..

§ 3. U can do what u want with the Sources, copy, modify, build your own custom kernel etc...

§ 4. I'm not SAMSUNG, that i can give u support, or build for everyone here an different kernel.

§ 5. I'm not here to make money... donation button is just to show an "special" appreciation as only an "thanks" pressing

Kernel suggestions

Hey ace2nutzer! What time would it take to get support for memory swap on this kernel? With that we could expand ram for better performance and there are no kernels for ace 2 that support this ATM. Oh and btw, this is a nice kernel :)
[Galaxy Ace II Android Development] ace2nutzer:
@up

I've disabled swap + zRam in Kernel.. that not improve performance.. it can only improve multitasking.. but than less battery lifetime and less ram speed.

U can try to enable the two things (KSM) in performance settings to improve ram usage .. (better multitasking), but not tested by me if this is really an improvement... .. just try it ;)

I'm really happy when i've done to fix random reboots on OC .. It's for me also unstable on OC .. ... that sucks ;)

After that i can improve RAM usage.. but for now, stability is more important... :fingers-crossed:
[Galaxy Ace II Android Development] MrBlackCore:
Can you put swap + zram like and option in performance? Disable them by default but leave the option to enable them because some of us really need it. Just a suggestion. Otherwise great work on the last kernel update.
[Galaxy Ace II Android Development] crisis_trustee:
There are two kernels in Dev-Host - from 19.12.2014 and from 20.12.2014.

What is differences between these two kernels in?
[Galaxy Ace II Android Development] newhalo:
Good afternoon guys. Now I've got jelly bean 4.1.2 with ace2nutzer kernel, but it's not so good...... so I want to install this rom, but before I need to know some things from you:

1) do camera and video recording work?

2) is everything working?

3)how is this Rom for you?

4) is this rom better than Aosp 4.4 by slv96 ?

Bugs and Issues 20161227 ROM:

-CM Browser: Some web pics are broken - CM Sources bug

-Device encryption doesn't work

-CM File Manager is not stable - CM Sources Bug

-Camera/Camcorder is buggy, but works anyway

CM11 20161227 for "codinap GT-I8160P" (Not GT-I8160) :(

RESULT: CM11 20161227 , CM11 20161208 , CM11 20161126 , CM11 20161122 ( Not Stable:mad: )
[Galaxy Ace II Android Development] andon0v:
It is for codina... just edit some lines in build.prop file....

The latest builds are stable for me even the performance is much better.

md5 download
[Galaxy Ace II Android Development] ace2nutzer:
Can u maybe explain what u mean by "but it's not so good...... " ??

1.) Yes, Camera + Camcorder works, there are only some minor bugs, compared to the Bugfree Stock ROM 4.1.2 :o

But it's still usable.

2. Nope, read Post #3.

3. Hmm great, but it's time to change, at least for me ;)

4. Personally i didn't test all custom rom's ... now i'm using this CM11 for years ... and according to what other users reports, this rom is so far the fastest custom ROM for the Ace2.

There is no one real codinap ROM ... they are ALL for GT-I8160.

U can create a GT-I8160P ROM by flashing this:

http://www.xda.mister-freeze.eu/XDA-files/ace2nutzer/CM11/codinap/

after the GT-I8160 ROM !

They are all stable, don't know what's wrong with your Phone.

If u want any help, u should provide logs + write what is not working for u.

Anyway, any reports without logs, (last_kmsg + logcat) will be completely ignored.

Taman ? :highfive:
[Galaxy Ace II Android Development] ace2nutzer:
For sure u're NOT remembering correctly.

Install Stock ROM 4.1.2 without to install ace2nutzer kernel, then u know it better what is "slower".

As for the Cam: sometimes it FC if u switch a few times between cam and camcorder.

And the flash-light when recording a Video works here a bit strange, at least compared to the Stock ROM:

on Stock ROM:

When u record a video, the Flash-light stays at minimum. Also after Focusing.

on CM11:

When u record a video, the Flash-light starts at lowest brightness, but every time u focus, it's increase the Flash-light by one step... till to the max of 16 Steps if i'm not wrong ... and theoretically if u record very long at this max. Flash-light, there is some chance to burn the LED ....

Can't say if it's just CM "feature" or if it's a bug on our Camera Driver.

Also an user reported better Quality for Foto or Video when using the Stock ROM 4.1.2.

Other than that, the Camera is working fine.
[Galaxy Ace II Android Development] ChronoMonochrome:
Do you have logs for this issue? If this is due to calling to STE codecs with the OMX index unsupported, might it be related to getSupportedProfileLevel fix? If not - was it present in earlier builds without the some most recent security updates?

Does it have something to do with flashlight interfaces upadtes in kernel? It works normally on RR N for me, also I don't remember if I was ever having such bug since 4.4.4. You might want to check what flashlight interface uses camera.

I'd rather say it's AOSP webview incompatibility with our OpenGL blobs. It became too obvious when it turned out that video playback isn't working in stock browser in 7.1.1 (in browsers such as Opera, it works, however).

I remember I was having issues with apps installation from CM Filemanager on CM14.1. Is this issue meant here?
[Galaxy Ace II Android Development] slayer_007:

[Galaxy Ace II Android Development] Farzin 073:
Hi . I have 2 quistions ;

1-Can I use your rom but use other kernels like chrono kernel ??? Cause I want TWRP recovery ... Is that ok ??

2-I,m on Cm 13 right now . For flashing your rom just wipe system and flash Cm11 ???
[Galaxy Ace II Android Development] shaqman89:
1. Yes, you can.

2. You could try, but it's not the recommended way. In most cases, it could work with some apps that force closes could be dealt by clearing the apps data.
[Galaxy Ace II Android Development] ace2nutzer:
Wipe data.

I can provide logs by a chance. I believe it was always present.

Hmm good idea, maybe i mess it up :)

Ok, i'll update Post #3. Thx. - So always the same **** :D

Nope, the Filemanager just freeze and FC sometimes when u open a few interfaces in /sys.

Sometimes very quickly, and sometimes u can open interfaces for 5 minutes without to FC.

Anyway, i found out that the rate of FC is much higher when the I/O load is very high, which is the case after boot when media scanner is running ! - But so far i can't get the point what is the real cause of this.

Theoretically it could be one of those things: Binder driver from kernel, sioplus io-sched, zRam or its LZ4 implementation.

But for now I'm trying to import Stock GB MCDE Driver to Stock JB / CM11 - CM14. - That really sucks.

Once the LCD is a bit hot, it causes immediately BS in cwm.

And even more painfully on Stock JB i had to force APE 100% for screen ON, otherwise with APE 50% it causes even LCD issues during booting^^.

If i'll manage to import it, it's save around 10% current drain on idle.... and up to 20% powersaving on stock JB.

And no one will have LCD issues, unless the LCD is really buggy, also tuning LCD freq is then not needed anymore.

Why i can't access sdcard1? I flashed this cm-11-20161227-UNOFFICIAL-FULL-codina.zip and kernel ace2nutzer.kernel.4.4.x_20170101_codina.p.l.zip ?
[Galaxy Ace II Android Development] ace2nutzer:
Sdcard1 = sdcard0
[Galaxy Ace II Android Development] Al Arsyadi:
So you've disabled sdcard0? How to make system read sdcard0?

PS: Ace2nutzer app does not work here, always get license error. :confused:
[Galaxy Ace II Android Development] ivan'z:
Why doesn't have internal sdcard? I have some backup files in internal sdcard, how to get back internal sdcard (not exsdcard as sdcard)? I flash kernel nosdcard but can't access exsdcard, and I flash normal kernel I got back my exsdcard as sdcard.

Sorry for bad english
[Galaxy Ace II Android Development] ace2nutzer:
yes and no, this ROM can't handle both sdcards at the same time, as it would cause app installations issues.

So u've to decide if u want to use the Phone with or without sdcard.

In a case of sdcard usage, just copy all files from sd0 to sd1 ... then use repartition zip (read post #3) and flash kernel

The repartition + kernel with the name: "nosdcard" is for the other case if u don't want or have sdcard.

U can try with some older kernel version ... read changelog to find out which version have both sdcards enabled.

If u want to use it, uninstall it, and install it again from Play Store, then it's unlocked. But be aware that it cost 4,99€ European Zone ... for other Countries it's an automatically calculated price from Google ....

I know that 4,99€ is maybe too much money for some poor countries .., therefore i'll very soon adapt its price manually.

If somebody really want my app, but u really can't buy it, (no money or whatsoever) then Post here, we'll find a Solution ;)

btw: @ all users that already purchased my App:

First of all: THANK YOU !

Second: please rate my app and leave a nicely Comment :)

Please don't rate or comment negative, if u've a Problem, u still can ask here in the Thread or Contact me.
[Galaxy Ace II Android Development] Al Arsyadi:
I think i will use this rom even no sdcard0, because my phone is running normally. :D

For ace2nutzer app, can i use similiar app like kernel adiutor?
[Galaxy Ace II Android Development] Farzin 073:
Very good ROM . just a problem : some times screen looks bad I don't know how 2 explain it looks double lines .

Is the Charger Control Currency working fine for everybody?

I am testing it with my USB load tester and it says 440-550mA mostly, I have set 700mA in Kernel Control app.

Whenever I set something below the default value, the load goes down below 50mA (yes 50).

When i set it to 800mA the load is then 660mA, but after I set it up to something higher it reverts to 550mA.

The settings in Kernel Control app remains the same (does not change) as everything is alright.

If that might help after installing this ROM+Kernel my battery capacity is around 900mAh (brand new is ~1500), also I have and 1A charger.

Don't know how it was before flashing but for me it seems like the capacity decreased a bit (even on power save mode).

Can't see any related errors in logcat either.
[Galaxy Ace II Android Development] Farzin 073:
Ss
[Galaxy Ace II Android Development] ace2nutzer:
yes, works as well ! But u'll waste some internal Space ... that u can recover and use it for apps, by using repartition zip :)

as for the app: i've checked right now kernel adiutor .. and it seems that u'll only be able to change CPU Freq ... nothing else useful. And for that, u don't need that app, because u can change CPU freq in ROM itself ...

(settings ---> performance ---> CPU)

But My App can do a lot of more things ... it's Device + Kernel Specific ... (but not rom) .. and it's even useless for other phones... So u can't find such a "universal" app.

Yeah .. that's an known issue .. that usually happens when the Phone is very cold.

And I can't buy your kernel app cause i ,m Persian and we can't buy apps on play store what should I do ??

Well, for such extreme Cases like "i can't buy on my country" or "really no money" .. then here is a little Solution at least for now .. and i can't say exactly how i'll manage this for the future ...

So we start a little PROMOTION:

LIMITED !!

Ok, here we go!

Share this Link:

https://play.google.com/store/apps/details?id=com.ace2nutzer.settings.device&hl=en

to one (or two) of your Social Networks ...

then let me see your Post, by sending me the link to my private messages here on XDA ...

And i'll answer you with an Coupon Code (100%)

If even this is not possible, then try to buy it by using the link above, but use an computer or laptop and log in with your usual Google play account u use for the Phone... once u've purchased over the PC, it'll install automatically on the Phone later ... ... maybe works !

Disclaimer:

Do it at your own risk ! - Because i'm not aware about your laws in your Country !!
[Galaxy Ace II Android Development] ace2nutzer:
whats wrong there ?

Well, try latest kernel ... maybe it's fixed ... i changed something.

If it'll cause LCD issues, make sure LCD freq is not tuned. So don't use old NT-APP and disable "tuned freq" on new Ace2nutzer App from Display Section.

Believe me, there is nothing wrong :)

That's normal ... u've probably old battery with different impedance than an new battery ...

All normal .. u'll see that with time, it'll drawn less currency. u can workaround this by simply setting higher current.

Yup, also normal ... that's an reset ... u've to wait a few seconds ... then it'll use new current u've set.

Also normal, this is because your USB Charger can't handle any higher current ... then the Charger driver in kernel see that Voltage drop, and it sets the current by one step back ... which is always 100mA Step.

Such a drop u can see in the Interface:

u can type this in term. emulator:

cat /sys/kernel/abb-charger/charger_curr

When there is a drop in Voltage ... because the USB Charger is on its own limit... then u'll see something like this:

/* Print VBUS dropped warnning */
if (bVBUSDropped) {
sprintf(buf, "%s*******************\n", buf);
sprintf(buf, "%s* VBUS DROPPED!!! *\n", buf);
sprintf(buf, "%s*******************\n", buf);
}

(taken from source code)

Sure it'S new ?? - likely that it's a fake battery and charger ... !

Only just because there is printed "1A" it doesn't mean that it'll really provide 1A output current !

Most of the very cheap 1A USB Charger are just fake charger from China or other Countries.
[Galaxy Ace II Android Development] `NX:
Well, it is charging my other devices at up to 900mA. I also have few other chargers and they behave the same with this device.

It might be that the battery is old as you said, just wondering.

Same problem like me, lcd got double layer... Fix when lcd become hot
[Galaxy Ace II Android Development] ace2nutzer:
Yeah, that's probably the reason for that... it's probably to prevent charging a old battery with high current, which is probably too dangerous.

What is your LCD Type ??

anyway i've s6d, and i had same issue with double layer ... but i was outdoor ... very cold .... so i just disabled "tuned freg" and the issue was fixed .... and if i enable it again, it was double again .... later in a warm room at home, i tried enable tuning again, and the LCD was working normal.

Try this again, otherwise i'll rework LCD Settings once again.

btw: just to clarify, it's not my bad, it's just a samsung Bug, generally speaking it's an incompatibility with any Android Version higher than 2.3.x..

We're currently trying to port fully working 2.3.x MCDE (LCD) Driver to every Android Version higher than 2.3.x. but it seems that it's not that easy.
[Galaxy Ace II Android Development] Farzin 073:
