Not a must, but it's better if u don't want to waste some internal space, other than that, it works as well.

Uninstall the app and buy it over play store.

@ ALL

Updated prices .... Final now !

Honestly that sucks for me too, so it's already reverted on sources .... so next build will have this charging system:

charging to 100% and hold the 100% !

4,35V - 1500mA (according to the orig. battery) @ 150mA termination current ... (10% from capacity ... this is the default for li-Ion batteries)

Ok, but i think it'll not change that much ... probably only 10 minutes + ....

From day to day and for every charge cycle, the capacity of the battery will decrease .... chemical process ;)

Ok, but this is very painfully method for the li-ion battery. it'll decrease its capacity very fast.

Maybe u can try an app (maybe tasker??) that stops charging @ 90% .. that'll help a lot to enjoy the battery for some additional Year or even Years ! - For just having 10% less charged Battery.

Anyway, u can still start the day with 100% charged battery, if u use that way:

limit charge @ 90% for the night, and when u wake up, simply disable that limit, and it'll charge to 100% .. then once it's fully charged, remove it from power source as fast as u can.

This is painful too for the li-ion battery, but way better than hold the battery for hours over night @ 100% !!

hehe Thank u very much !! :good::good::good:
[Galaxy Ace II Android Development] Kurajmo:
Newest version work very good.

Only one issue i discover.

When i use opera Mini Newest version on Ace 2 with chrono_kernel_r2.24

This kernel have stock jb partitioning and i use him.

On my screen sometimes animation is slow and i can see black bug.

I think this is only opera Mini bug. Because other app work without this issue.

A i forget meant something.

I found other bug more.

I tried install Simple last fm scrobbler on cm11.

And the same issue as on cm13 appear.

App cant be work properly without authenticate.

Something like that appear When i launch Simple last fm scrobbler.

I found other app to scrobble last fm.

But i think i meant this bug here.

I dont know why this stupid bug still appear.

Everything works fine.

Good battery life, good performance.

Almost all my app work without issue.

And i can make Photo with camera without sd card in Phone.

I tried on Newest version without crono kernel.

And camera app fc itself.

Thats all from me.

Thanks for this rom.

And good work ace2nutzer i really appreciate you work.

On this custom rom old Galaxy Ace 2 work without issue. And can be use as replacement second Phone.
[Galaxy Ace II Android Development] Bib_x:
If i use my ACE2 with sdcard and your sdcard kernel - when i remove the sdcard - can i still use my phone or will it stop working? Which things are moved to sdcard?

And what about wearleveling? Will it damage my sdcard over time?
[Galaxy Ace II Android Development] ace2nutzer:
On Next Version we'll have 2 different kernel: default one with access to both sdcards ... (not swapped)

and one version "sdcard_only" which will use only micro-sdcard as sdcard0 .. and will ignore internal sdcard0.

So everyone can decide what is better for ....

Proper cwm_reparted are also changed ... both versions ....

Try it ... it should work anyway ... but some apps that requires sdcard space ... i.e. Camera App .. will then FC.

Next build will use both sdcards as i said ...

[MENTION=5840412]ace2nutzer[/MENTION]

what do u mean by "small percentage" ? - Low Batttery ?, if so, on which percent is it starting this issue ?

I suspect it has smthg to do with a very low battery capacity ... (nearly dead battery)

Hello Ace2nutzer!

The initial value is typically charge 10% .If it is on display jumps to 2% of the charge, but off screen than a normal charger.
[Galaxy Ace II Android Development] Bib_x:
Please can you tell me, where whatsapp does store the images and videos with your rom?

That´s the most biggest problem of the ace2 from my wife in daily use. No more free space.
[Galaxy Ace II Android Development] Culateralligator:
[MENTION=7759964]Sd card[/MENTION] (external), if you're not installing nosdcard kernel and don't change anything.
[Galaxy Ace II Android Development] Kurajmo:
Ok i wait for new version.

I try this new version without crono kernel.

Anyway thanks for all you work ace2nutzer.

Greetings
[Galaxy Ace II Android Development] Mokujin5757:
Done this and have been using like this for 3 days . Still happens . Huge thanks for helping me even if it didn't work .I'll be making clean installation after I backup my apps . Or should I wait you to release new version of kernel+rom ,and then make clean installation ?
[Galaxy Ace II Android Development] ace2nutzer:
@up

if u restore the apps WITH Data .. then it's NOT a clean installation ... and it's likely that u'll restore any Problems back.

U can try a clean installation ... but probably u'll end up to decrease the amount of the installed apps .. in order to reduce the RAM usage ... or maybe use greenefy if it helps ... personally i delete all apps that i don't need ... and the Phone is quite fast ... battery life also better .... ;)

PS: Yes, better to wait new Version .....

I''m sorry, but i didn't understand what u mean.
[Galaxy Ace II Android Development] AkosPaha:
Hello Ace2nutzer!

When it comes to the new version is about?
[Galaxy Ace II Android Development] Kurajmo:
Just wait patiently for new build ace2nutzer have a life you know and think he dont everytime modify etc cm11.

Everyone have a life, modding isnt important.

You meant something about you battery.

I dont know i understaund correctly.

You finish charge you phone with 10% battery.

You Block phone. You unlock you phone and see battery have 12%?

Thats you have in mind?

For me this looks like weak battery.

And i think you need to replace you battery.

Ace 2 is old phone.

Battery is Almost dead when is original from Samsung. I think.

In my Ace 2 i replace battery Because one old Almost died when i buy second Ace.

But now this new battery work very good.

2/3 days when i do not use phone.

6h when i heavy use phone

Sorry about my poor English.

I dont speak this laungage everyday in my country, and i still learn this laungage
[Galaxy Ace II Android Development] Culateralligator:
My battery has just one year, a Polarcell with 1700mah... I think it's in good conditions yet.

But yesterday it made a strange thing I hadn't seen before... Unplugged and with screen off, it had 10% and after half an hour without touching it, it displayed 18%.

Just saying for curiosity.
[Galaxy Ace II Android Development] giginski:
i have been noticed that sometimes when i unplugg charge my phone dosent go to deepsleep, then i have to restart phone.
[Galaxy Ace II Android Development] Kurajmo:
My two battery works normal.

And i have original battery for Ace 2 1500 mah

I use greenify with xposed and i greenify almost every app system etc.

My battery work normal.

As i Say.

When i heavy use phone.

Like music, scrobble last fm.

And browser internet all in the same time.

My battery work 5/6h.

But without usage my battery can work 2/3 days.
[Galaxy Ace II Android Development] Cursed Chico:
My battery also started dischargng while on battery. The battery is reducing on battery. I need to restart. sometimes it helps
[Galaxy Ace II Android Development] Cursed Chico:
I cant use camera for most of times. For camera app, facebook, whatsapp, instagram.

messenger give this error

lease wait for the video to finish sending before recording a new one

but not others give error but i cant record vdeo.
[Galaxy Ace II Android Development] msq2:
when there is a new version ?
[Galaxy Ace II Android Development] hanker_de:
Please follow the XDA rules and don't ask for ETA...

Thanks!

Another German.
[Galaxy Ace II Android Development] Culateralligator:
Well, today I was talking about this issue and I remembered I was at my terrace having a sun bath with high temperature while using the phone for an hour.

Then I put the phone in another room on a cold place and didn't use any more.

And that's why it step from 10% to 18% when it reached low temperature after having high.
[Galaxy Ace II Android Development] ace2nutzer:
It's Possible that the battery is now a bit "broken" .. when it's jumping on % for almost no reason...

In the End it's caused by too much unusual differences in Voltage ... ---> "voltage Drops"

That mostly happens when the battery isn't more in best conditions.

Anyway, as long everything works still good and the battery lifetime is still acceptable AND very important: the battery isn't bloated ... (!), then u don't need to worry.

As i said before ... Li-ion battery don't like to stay too long on 100% or too low states like <10% ... such conditions hurt the battery very fast, and then such things happens with voltage Drops.

An new Battery can hold the Voltage almost all the time "stable", even on big current loads, so % Drops will not happen.

-----------------------------------

As for Updates:

Actually i'm busy with my private life, so Ace2 development was very low on last days.

Now this Phone is very old .. and it's nearly to its end-of-life .. i.e latest CM11 Build is still on latest cm sources ... it seems that CM-Team stopped to backport some Security patches to CM11.

So there is actually nothing to update.

And honestly it's even not needed, most of them are Buffer over/under-flow Patches ....

And since this CM11 and Kernel is compiled completely with "-fstack-protector-strong" (google it), i don't care much ! ..... That Flag already do the Job :)

Anyway, some small kernel optimizations are coming .... can't say the day exactly ... but on next days.
[Galaxy Ace II Android Development] msq2:
I disconnected the charger immediately have a drop in battery voltage to 4.15V but sot at low brightness reaches 3-5h, worse at higher illumination.

The new version of I'm asking because I read that the new kernel thread to read the internal memory and external, which would be good for the phone my girlfriend because of this reason, it uses the version of November last year,

Thanks for reply, and sorry for my english
[Galaxy Ace II Android Development] Fabbb2:
Thanks again for you great job.

Could you compile the latest kernel with normal behaviour for sdcard0 & sdcard1 (when you have time) ?

Have a nice day
[Galaxy Ace II Android Development] Sidebandit:
As for end of life nah, there is good activity for this device in this forum more so than many newer small screen phones and surprisingly some of them still using the Mali 400 gpu. Great rom and kernel, as said with others a return to 1GB storage and external sd. I expect it would have to be reparted again?

:good:
[Galaxy Ace II Android Development] tursey:
Does full ROM 20170207 come with Kernel 20170207?? Must I install the Kernel after install the ROM? thanks!
[Galaxy Ace II Android Development] gepel:
This ROM has kernel build in, so nothing extra has to be install.
[Galaxy Ace II Android Development] Fabbb2:
I have a question for everyone. Is it possible in this rom to use emergency numbers which can be called from lock screen (ICE) without installing an app ? If yes, how to do it ?
[Galaxy Ace II Android Development] Mokujin5757:
It is at the bottom of the lock screen if you are searching for emergency button .
[Galaxy Ace II Android Development] Mokujin5757:
I have done this as you said and wasn't working .I have commented on this where I was saying that it didn't work and gonna make clean installation . I have made it but the problem is I still have instant crashes but it doesn't lag my phone as it was before .I mean it just freezes for a moment and gives crash error . And back to normal . Sorry I couldn't wait for a new version of ROM coz you said that ROM was complete , nothing to update , but there will be kernel update .
[Galaxy Ace II Android Development] ace2nutzer:
Sure ? - From 100% and then unplugging the cable ... if it's a original 3,8V Battery then it should show 4,25V ... (for 100% without cable)

If u've any 3,7V Battery, then it should show 4,10V without cable @ 100%.

So if it's original samsung battery, then it's broken, too old or just a fake-original battery.

Yes, next kernel is again with both sdcards :)

But probably without "swap storage" on Kernel APP ... because that's a quite messy solution.

I'll provide 2 versions... normal and swapped sdcards.

Maybe works better, if it's swapped in ramdisk.

Yes, with brand new cwm reparted :D

it's built-in, and flash kernel only if there is a newer version than a built-in kernel ... i write usually in changelog always the Version of kernel built-in :)

Ok, only crashing apps ?? - No random reboots or soft reboots ??

That's no problem :)
[Galaxy Ace II Android Development] Mokujin5757:
Actually it was happening before I clean installed . Soft reboots was happening but not that much , but when it happens I was not able to control wi-fi . Whatever , it was before I clean installed . But for now (about one day experience ) there only happened 2-3 lite kinda crashes (I wrote my latest comment after these crashes happened ) . No reboots yet , and my phone is just fast as I installed for first time .Thanks again for everything .
[Galaxy Ace II Android Development] Kurajmo:
This rom is awesome.

Old Ace 2 still can handle newest Android games.

Today i succesfully launched and played Corpse Party BLOOD DRIVE from Google Play store.

For fun download this game. And launch on two phone.

LG k3 and Ace 2 with cm11 from Ace2nutzer.

On Ace 2 this game is little slow.

But still playable.

Meh i know what i do today night.

I tried play this on stock cm setting.
[Galaxy Ace II Android Development] lv-xda:
My ace2 (GT-I8160 with microsd, CM11-20160901) just got bricked during reparting. :(

Did precisely according to manual/recommendations (post #3):

After that i can no longer boot into recovery (reboot loop). What went wrong?
[Galaxy Ace II Android Development] ace2nutzer:
Flash odin Kernel and continue the procedure.

At the end flash latest Kernel.
[Galaxy Ace II Android Development] lv-xda:
Well, i did re-partitioning successfully. Actually re-flashed stock rom, cwm, installed cwm_cm11_partitions_layout.zip, but this time i didn't reboot before continuing.

Maybe power-off step is unnecessary and should be omitted in the recommendations of the post #3 as it might "brick" the phone?
[Galaxy Ace II Android Development] ace2nutzer:
Nope, after changing the Partition layout, it's needed to reboot recovery and then formatting, Otherwise it can't format new Partition size because of missing re-initilization of new layout.
[Galaxy Ace II Android Development] Icehockeydroid:
After repartition I made a clean installation of latest stable build and kernel. Mobile is performing good. Though, I am getting a lot of random reboots every day :(.

I had this issue also after some time with a former build, that's why I made a new installation.

Since hardware is now 5 years for me it looks like a hardware issue. But is there a way to find out what is causing these reboots? I collected last syslog after reboot (see attachment).

Thanks in advance.
[Galaxy Ace II Android Development] Kurajmo:
I found a bug yesterday.

And i see this bug second time.

When i use Ace 2.

For web browsing. Download video etc.

My singal is lost.

I download something from web. And my phone lost signal.

I tried turn on aeroplane mode and turn off aeroplane mode.

But this cant help.

I must reboot Ace.

And signal back.

This is strange case i have very good signal from my network provider.

Ace2nutzer can you fix this issue?

Why this happen?
[Galaxy Ace II Android Development] msq2:
Często tak miałem przy korzystaniu karty SIM z Orange.
[Galaxy Ace II Android Development] ace2nutzer:
Is it also rebooting without to overclock CPU/GPU and without to change settings in Kernel App ? (Especially CPU/GPU Voltage Settings)

Also u shouldn't use CK-Settings APP ...

If it'll still not help, then try to delete the File /system/etc/init.d/01_zram and reboot the Phone.

Let me know if it helps.

Strange ... do u mean 3G Network ?

If so, check Settings --> Mobile Network .. and check WCDMA for preferred Network.

Maybe it was switching between 2G/3G .. and it may stuck at 2G or whatsoever ....
[Galaxy Ace II Android Development] Kurajmo:
Yup i mean in 3g network.

And yes network is set to WCDMA only.

And yes i use Orange sim card
[Galaxy Ace II Android Development] ace2nutzer:
Ok, maybe it's Orange issue.

I dont have this issue.

Try another Provider.
[Galaxy Ace II Android Development] Kurajmo:
I tried on Virgin Mobile card.

This error still is.

And randomly happen.

I want download something from web (video from porn site).

With opera Mini. And my signal lost.

Yeah i know im a evil person download and watch porno from web.

But its strange. In lg k3 i dont have this error.

Never something like that happen.
[Galaxy Ace II Android Development] msq2:
Haha, spróbuj docisnąć karte sim kładąc na nią kawałek papierka w końcu to stare telefony już i mogą być pewne luzy w wejsciu.

podaj jaki masz baseband, u mnie na I8160XXMF1 problemów żadnych nie ma, nawet hdvoice działa odkąd wgrałem tą wersje
[Galaxy Ace II Android Development] Kurajmo:
Pisz po Angielsku bo zaraz się moderacja przywali żeby po Angielsku pisać.

Już nieraz widziałem takie zachowanie tutaj.

Anyway my Baseband is I8160XXNB1

And this problem happen.

Today i try push little my sim card with paper. Maybe this help a little.

But is strange.

This bug appear only when i download video with opera Mini.

I have xposed and greenify.

Maybe those apps someway make a error.

I don't know
[Galaxy Ace II Android Development] ace2nutzer:
Don't know whats wrong.

I don't use greenefy nor xposed.

No Problem with stock Browser .... so u may want to report this issue to the opera mini thread.
[Galaxy Ace II Android Development] Kurajmo:
Ace2nutzer

Any news about update?

I ask Because today my Ace 2 freeze.

When i use Apus Browser.

I just search something in web.

And my phone reboot itself.

Its really frustrating.

I think about to reinstal cm11

And format this one sd card 16 GB.

Use my Toshiba micro SD card as internal memory.

Then clean install cm11

Without xposed.

I think this stuff maybe cause problem with cm.

I may use this card with Ace 2.

But first i do backup all of my data.

Any news about update?
[Galaxy Ace II Android Development] ace2nutzer:
It still can take one week. I'm still busy.

But as for reboots:

Usually the ROM + Kernel is stable.

So if it's not stable (ramdom reboots), then it's probably caused by Filesystem Errors .. especially /data partition and sdcards.

To Fix it, only format those Partitions helps, restore then later the old data isn't a problem.

If that'll not help, then remains only CPU Voltage selection.

Temp Fix to find out if it's really a problem of Voltage:

Set min & max CPU Freq to 800Mhz .. (don't use perf. profile for this test-time) and use the Phone for some hours or days... if it's stable, then that's was the problem (report that!)

Don't worry, deep sleep will work anyway.
[Galaxy Ace II Android Development] Kurajmo:
I try this CPU freq today.

And i do backup everything from sd card.

Then i format this card 3 times in Ace 2.

And clean flash latest cm version.

And i wait for update.

I have a Hope this help.
[Galaxy Ace II Android Development] Icehockeydroid:
I don't use any overclock or additional Kernel settings ... also not using CK-Settings-APP ....

Deleting /system/etc/init.d/01_zram seemed to help. Phone was running one whole day without rebooting, though this morning it rebooted twice :eek:
[Galaxy Ace II Android Development] ace2nutzer:
Ok, try to use min max 800 for cpu.
[Galaxy Ace II Android Development] Kurajmo:
My issue disappear when i set CPU freq min to 800 and max to 800

Battery drain is faster i think.

But i dont have any error now

I wait patiently for new build.

Now i backup everything from micro SD card to cloud.

I dont have a PC Because my laptop is broken now.

And i must do this now
[Galaxy Ace II Android Development] ace2nutzer:
That was only for testing ...... so don't worry about battery.

That's now already a good found! - Thanks !

It looks like that the 150Mhz Step isn't stable ... ---> too low Voltage :)

This caused miscalculations when switching between 150 <--> 800Mhz and for result it causes freezes and random reboots.

I'll tell u later how to find out a stable voltage for 150Mhz Step ... easily with term. emulator app.

Then i'll code the new stable voltage for the new build.

[MENTION=4802494]Kurajmo[/MENTION]

How-to:

type:

su
cd sys/kernel/liveopp
cat arm_step00

now u see the actually Voltage:

As u can see we've 0x18 which correspond 1000000 uV or 1,00V.

We can Overvolt in 12,5mV steps ...

so to overvolt, just type this:

echo varm=0x19 > arm_step00

and check the result with:

cat arm_step00

now it's overvolted for one step ...

after this, don't reboot, otherwise it'll reset all changes.

Changes in Voltage is immediately active.

Now set back min. freq to 150Mhz ... and test if it's stable now ...

it should run at least for 2 Days stable.

If it's still unstable, then increase again the voltage even more...

After an random reboot u can set directly an higher voltage ... without to increase step by step.

So Voltage Table is this:

0x18

0x19

0x1a

0x1b

0x1c

0x1d

0x1e

0x1f

0x20

0x21

0x22

0x23

0x24

0x25

Last one 0x25 is the Voltage for the 800Mhz step .... and the first one 0x18 is the default voltage for 150Mhz step.

So overvolt always for one step ... and test stability ....

Report a stable voltage ....

Done :)
[Galaxy Ace II Android Development] Kurajmo:
Meh no need.

I just use 800 freq all the time.

Battery in Ace 2 is old and low capability.

Ace 2 fast charge with charger.

I only mean this cause i noticed faster battery drain.

Thats all.

No need to change anything.

But thanks for help anyway
[Galaxy Ace II Android Development] ace2nutzer:
Yes of course .... that's why u should find stable voltage ... then u can use again min 150mhz .. then there is no increases at all in battery drain.

But if u don't care much about Battery Lifetime ... then use static CPU Freq.
[Galaxy Ace II Android Development] Icehockeydroid:
hmmm tried it with min max 800 for cpu ... phone is still rebooting twice a day ... Anyhow deleting the File /system/etc/init.d/01_zram helped with reducing reboots.
[Galaxy Ace II Android Development] ace2nutzer:
are u sure it was fixed to 800Mhz ? - Once u set min 800MHz then DO NOT change performance profile.

Otherwise it'll reset back to min 150Mhz.

U can also try with fixed min max 1000Mhz.

Anyway, i'll increase for next build the CPU Voltage, and trying to improve Memory Management Stability.

According to your Log, some error accours while RAM was quite full.
[Galaxy Ace II Android Development] Kurajmo:
I have question.

Today i make backup all my data from micro SD card.

Finally 16gb send to cloud.

And my question is.

How i can complete wipe my sd card.

Without use pc?

For now i dont have access to any pc.

I backed up all my data.

But how i can wipe my memory card?

And how i can install newest cm11 build without use memory card?

I know when i flash newest build.

Then my micro SD card well use as Internal memory.

But my question is.

Is posibble to install cm11 Without sd card?

I just want install format my card cm11 Without card.

And put my card as internal memory.

Is possible?

Ace2nutzer maybe you can help?
