@ace2nutzer

Just stop this development! Please! It is pointless ...

I had a hope to buy brand new mid-class phone like SIII Neo or SII this year, because Ace2 always felt slow. Two and a half year ago me and my friend bought phones. I bought small i8160 and he twice as cool i9100 with bigger screen, faster CPU and many features, that Ace2 did not had.

I was like :eek:

He was like :laugh:

Now his wonderful amoled screen is bluish with burned-in icons, his battery lasts for couple of hours, he got one crack on Gorilla Glass screen and CPU is not so fast as it was before. My Ace2 in comparison still have same bright as new IPS PLS screen, new 3800mAh battery, fits in one hand perfectly and does everything perfectly. It is now twice as fast as it was when I bought it! Yeah. I installed some time ago stock GB and JB from Samsung just to compare. It is damn faster! Also due huge battery and yours (and ChronoMonochrome) sick ideas I charge Ace2 once a week! This suppose to be forbidden for people using smartphones! With latest kernel Ace2 overpasses SII with ease. Even Real Racing 3 works faster on or phone. MP1>MP4 wtf?:eek::eek::eek: This damn thing is even unbrickable since jtag port pads are easily available under battery. Sometimes I compare my Ace2 with my friend SII.

I am like :D

He is like :(

Because of you I do not feel a need to buy new phone! I bought a mainstream Ace2 (CPU 800MHz/ GPU 400MHz) just to be sure that I will change it in 2 years into something more cool. Right now I have very handy phone running 1300MHz/700MHz with battery that lasts a week, easily to use one handed and I do not see any alternative to this phone. I even bought spare Ace2 for cheap just in case I will broke or loose this one.

Shame on you :fingers-crossed:

I don't have 1300 mhz stable, when I set it my phone rebooted almost continously, I almost have no time to reset it to 800 mhz. Now I'm testing 1150 mhz and for the moment no reboots.
[Galaxy Ace II Android Development] LyrixTheDj:
I have two device. First is my (black) and another one (La'Fleur) of my GF. My is older about 1 year than of my GF. I have stability at CPU 1150 MHZ, GPU 720 MHz, La'Fleur have CPU 1200 MHz, GPU 735 MHz. Only one thing is annoying its heating, but for Russian winter is cool stuff for hands. All devices run on ace2nutzer ROM with latest kernel.
[Galaxy Ace II Android Development] soko3:
Can you send me link of your battery? How old is it and can you tell me more about it?

send me pm, please :)
[Galaxy Ace II Android Development] miryn:
Sry for OT but i'd like to see a screenshot of your battery usage too arroyo.. ;)
[Galaxy Ace II Android Development] drhay:
Thanks a lot for your answer and link, i hope i can do it correctly.
[Galaxy Ace II Android Development] arroyo:
Sorry for offtop. I have bought 3800mAh battery from here:

http://www.banggood.com/Wholesale-3800mAh-Extended-Battery-+-Cover-Case-For-Samsung-Galaxy-Ace2-I8160-p-59444.html

It is very good quality. I have it since July 2014. Still handles power as new. Comparing to the new standard battery, phone lasts twice as long. It is also twice as thick (on thickest point 1.5cm) and twice as heavy. I do not care. This battery allows me to watch movies for 8-12 h constantly, track all day bike trip on GPS or play GTA VC for 5-6 hours in a row. I charge my phone once in a 5-7 days. I do not have a screenshot with total discharge, those are made just now:
[Galaxy Ace II Android Development] Souffre:
Could anyone upload test version 0115 f2fs codinap again (links below are not working anymore).

I'm using this kernel codina ext4 right now but I plan to bring back my GT-I8160 to GT-I8160P and format in f2fs.

I didn't test latest kernel but according to the latests reviews test version is better?!

Thanks a lot!
[Galaxy Ace II Android Development] ace2nutzer:
This is great, but charging this Battery always with the Standard Kernel will damage this Battery.. because the org. Batt. have 3,8V and this Extended Batt. have only 3,7V .. That means the programmed Samsung Charger in ALL Ace2 Kernels is only adapted for the 3,8V Battery.

What is the Problem ??

Charging this Batt. everytime @ 100% will overcharge the Batt. and it can damage .. (loosing capacity)

Simple Fix:

Stop the Charging @ 95% ------> This is for the 3,7V Batt. already 100% charged ;)
[Galaxy Ace II Android Development] xo.en:
Precious info..hm. It may explain various fails with such(nonstandard) batteries in early ace2 era. Now, with new solutions problem is avoidable.

(sorry for multiple edits, trying to be precise..).
[Galaxy Ace II Android Development] soko3:
Can we set "Control cycle charging" values in NT app and make phone automaticaly stop charging at 95%?

If it's possible and if i understand that feature :D

EDIT: Hahaha post #1111 :D
[Galaxy Ace II Android Development] ace2nutzer:
@up

Of course! Just enable Cycle Charging in NT-APP and set: Discharging @ 95% and Charging / recharging @ 90%

btw: Latest Build everything OK ???? - Ram Management, Stability, Smooth....
[Galaxy Ace II Android Development] soko3:
it's good, but 0115test is still more smooth than newest...

since 0115, cpu oc works for 1250 mhz (reboots on 1300), gpu can be oc to maximum, no reboots

that's all...
[Galaxy Ace II Android Development] ace2nutzer:
@up

Maybe smthg wrong with latest builds... but i've now completely re-configured the kernel.. upsoulutely crazy job.. :cyclops:

If anyone like to test upcoming Build ....:

Next Version / To do:

Max. Stability on CPU OC (to-do)

Better Battery Lifetime

More Speed

Much more responsive

Reduced Kernel Size a bit more

630MB RAM Available :D

For me it's working since 2 Hours really amazing... but i don't know if u guys will have again problems with sdcard / apps .. i don't hope this :fingers-crossed:

If there are any Issues in this preview1 Build... so pls let me know.. i'll fix it :)

This Time i've builded + uploaded all Versions... All Versions are in some minutes online... only in dev-host ... check this out.. and make your Ace2 fast like lightspeed :o:D:D:D

But as i said, it's really possible that there are some tiny or big Bugs.. but after find these bugs + fixing.. i'll make normal release... that means it's Beta Version :D
[Galaxy Ace II Android Development] bebolint98:
Hello! I test the codina ext4 prewiev1 but I have again problem with install app from play store:
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for testing !

preview2 is up !

I think it should work now :o

Pls Tell me if it works or not :good:
[Galaxy Ace II Android Development] MarquesYOLO:
I have SD problem on codina f2fs preview 1 too.
[Galaxy Ace II Android Development] bebolint98:
Now on preview2 it's work!
[Galaxy Ace II Android Development] Maev Maxx Damage:
Preview 1, f2fs - no sd bugs, I find it faster than 02.04 build :) thank you !

silly question - 16bit transparency - does it speeds up games somehow?
[Galaxy Ace II Android Development] VRDRBR:
i'm on preview1 and have no problem with appstore.

but i also didn't have the sd card/playstore problem in the last builds
[Galaxy Ace II Android Development] soko3:
Quadrant Standard says 3150 points (1100 cpu/450 gpu), even with Facebook, FB Messenger and Whatsapp running in background...

On previous version, i had 3050 wothout Facebook and FB Messenger :D

About 16-bit transparency

I heard from CyanogenMod developer that 16-it transparency is useless feature and increase performance just in theory...

Download some 3D benchmark apps and check it yourself, that's the best way to avoid silly quesions :D
[Galaxy Ace II Android Development] wolfensg:

Well I've tried every kernel since few last weeks and can confirm that although you are doing miracles in terms of performance and memory management the kernels still appear to have the "black screen bug" (all of them). The last kernel I've tried (the above one) seem to have the problem even in recovery (that was kind of new for me, and it took me a couple of reboots to boot up successfully into the recovery to actually see anything other than the "grey lines" :).

For now I think I'll stick with the kernel by PolishVodka but I'll keep an eye here for the news ;) Keep up the good work!
[Galaxy Ace II Android Development] bebolint98:
[MENTION=5840412]ace2nutzer[/MENTION] I have got a question.I try the latest preview2 or 0202 p7 kernel and some not soo late build but

I have got a problem when I browse on the internet or play fifa14-15 or other things my phone freezes ,I have got about six freeze just today, and I can't do anything so I need to press the power button 10 sec to reboot the phone and sometimes the phone go back itself to dalvik from ART.So what could I do wrong?:confused:
[Galaxy Ace II Android Development] RetZi4:
Hello guys.. My english is bad but i ll give a try :p

I have Ace II and i flashed it before 6 six months with Rox's ROM kitkat 4.4.3 version cm-11-20140607. These 6 months my phone overpowered cause before that i had the official jb :crying: I always had some bootloops and black screen issues but the last month is a bit slow too + my battery is draining very fast. Btw i didnt flash kernel. Can you please tell me where can i find the best ROM to combine it with this kernel??

And one more question cause i am a bit rookie with these things. Can i increase my phone's capacity and how? I have a micro sd 4gb but sometimes its not available to move some apps to sd so i get error while updating them for not enough free space..

Thanks :)
[Galaxy Ace II Android Development] seanmalto:
Hey, you have to try this build from cm11 and improved by ace2nutzer

1. http://d-h.st/IOc (ext4)

2. http://d-h.st/sxl (f2fs)

Im sure that many codina user use this build, and me too. Stable and less bug i think, just something like can not streaming video from some source like youtube by using a build in browser. Just use youtube, then the problem is gone :)

About increasing your storage capacity, you may use cwm reparted by chronomonocrome, then swap memory.

Just take a look at his thread, and do everything with your own risk.

The last thing, just flash any kernel by ace2nutzer and follow the instruction correctly.
[Galaxy Ace II Android Development] ace2nutzer:
Very strange ... i've this prob. sometimes too.. i'll make now new build with fixed sdcard bug.. and we will see if the Phone don't freeze anymore !
[Galaxy Ace II Android Development] RetZi4:
Whats the difference between these versions(ext4,f2fs)? How can i check it which one should i use?

And one more question. First i have to flash rom or kernel? and should i use factory settings and format all files before flash rom or clear cache and dalvik cache is enough?? Sorry for my dumb questions :eek:

Thanks for your time :)
[Galaxy Ace II Android Development] ChronoMonochrome:
This might be caused by disabled SPI CRC. Recently I've got this problem too, will enable SPI CRC and see if it helps.
[Galaxy Ace II Android Development] ace2nutzer:
Oh yes ! I believe u're right ! This Prob with freezing accours since i've disabled SPI CRC .. but i've changed many other things in defconfig.. so that i'm actually lost in settings.. but i'll test this too. i hope this is the real reason for that :) Thank u :o
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!!

Changelog:

20150207:

Better Battery Lifetime

More Speed

Much more responsive

Reduced Kernel Size a bit more

630MB RAM Available :D

Note: It's a bit different as preview2 Build ... (more optimized) .. sdcard Issue also fixed ... ;)
[Galaxy Ace II Android Development] RAPXT:
@up: Can you build a kernel from 15.01.2015-source, because i have to agree with the other users, that this kernel was the best till now.

What do you think, how long it is going to take for a fully functional & stable release of CM12 for the Ace II ? (don´t be stressed, i´m only interested)

And i reparted my Ace II to work with f2fs filesystem (as you described in 1st post). I have now 2,3 GB on data for installing apps. But thats not enough anymore, so is it possible, to make the partiton (of course for f2fs) a bit bigger? It is not possible to increase the partition without formatting, right?

Thanks for answering :)
[Galaxy Ace II Android Development] Maev Maxx Damage:
Latest f2fs build - so far no bugs to report, faster booting (28 secs, compared to 31 in previous 02.04.) Nice !!
[Galaxy Ace II Android Development] bebolint98:
Hello.I try the latest build but I have the same problem, my phone is freeze and can't do anything, need to restart with the power button.
[Galaxy Ace II Android Development] ace2nutzer:
Hmm strange... For me it's working well. Cpu & gpu clock? Build?
[Galaxy Ace II Android Development] bebolint98:
CPU:1000 Mhz GPU:705 Mhz

I use your 11/18 cm11 with 02/07 kernel.
[Galaxy Ace II Android Development] soko3:
hey, genious, try to use lower clock for gpu...

my phone also freezes when i oc cpu [MENTION=4724277]1300[/MENTION] and gpu over 700...

mine config:

cpu 1100 mhz, gpu 450 mhz and it runs some demanding 3d games with HIGH quality graphic settigs without problem....

why the hell you want to turn old granny into young girl??

this is ace2, former midrange, now it's low-end device.

okay, with this rom+kernel it's better than galaxy s2, but that's all... don't expect Galaxy S4 performance...

[MENTION=5840412]ace2nutzer[/MENTION], is it possible to make more free ram... i mean, my friend with new alcatel (!!) have only 100 mb of visible ram used by system...

if we had that usage, we woud have 530 ram free...

what is using half of our ram and can it be fixed in any way?
[Galaxy Ace II Android Development] seanmalto:
Go to the last page of cm11 from rox's thread. I've posting something there that maybe usefull about your question :)
[Galaxy Ace II Android Development] Danko Jones:
20150207 f2fs - best version for me so far! :good:

Had several issues with latest builds (blackscreens, freezes, bad responsiveness after some hours).

All gone with newest build after some hours testing. Improved score in Antutu. Much more responsiv.

max CPU 1200 Mhz, max GPU 550 Mhz (ws2401 driver)

Thanks! Keep it up!

Install from playstore minfree manager

And google for: android minfree values.

And i suggest to don't change the first 3 values.. They are affected to System stability

i'm talking about part of RAM marked with red line..

can it be freed a little bit?
[Galaxy Ace II Android Development] aj10:
[MENTION=5840412]ace2nutzer[/MENTION] i am using the latest build, and in settings > apps, it says i have used 1.1 gb and have 150 mb free. with the same apps, i used to have around 370mb free. i cannot download large files through the web browser. i tried to download a 12mb app from the play store, but it said i have insufficient storage. i am using dalvik and ext4 kernel. on your kernels from november-december last year, i did not have this issue. i have moved as many apps to the sd card (32 gb) as i can.

apart from that, the latest kernel has no issues so far (1.2 ghz).
[Galaxy Ace II Android Development] ace2nutzer:
I know what u mean... Yes it is possible.... But checking ram usage in this menu is really useless. To check all about ram used / free / cache / and swap, type in terminal Emulator: free

And to check disk usage of all Partitions: df

To change the amount of free ram and Multitasking things, read what i posted to u
[Galaxy Ace II Android Development] soko3:
well, terminal doesn't show too much infos ...
[Galaxy Ace II Android Development] snyfear:
Hi guys,

All my thanks and congrats for your kernel Ace2nutzer. I installed it for the first time one week ago and If I would know how much better it was compare to the stock one I would install it very earlier.

It was stable a 1200Mhz all the week, and with better battery life than before.

Today I was playing with the CPU overcloack menu and I pressed the 1300Mhz radio button without wanting it really. Phone restart immediatly and as the "keep setting" checkbox was enabled at this time, my phone is in infinited reboot loop.

I just have time to enter my secure PIN code and most of the time, the phone reboot before displaying the first icon.

How can I restore my CPU setting without factory setting? Is there a ADB command I can play from the recovery menu or something like that?

I also think to make a backup from recovery menu, transfert it to my laptop in order to modify the CPU setting inside the backup but I don't know where is it stored.

Thanks in advance for your help.
[Galaxy Ace II Android Development] fluffi444:
Yes. Use ADB in recovery with su

echo 1200000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Edit

And do this to be safe that system settings do not charge it again

chmod 444 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

After successfully boot do

chmod 644 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

[Galaxy Ace II Android Development] snyfear:
Thanks fluffi444,

I tried your commands but I probably do something wrong.

When I do a cat on your file it says 800000 not 1300000.

Anyway I played all your commands and did cat to verify and file was modified including the rights.

On boot same problem, reboot around the PIN code screen.

When I am back in ADB a cat on the file say again 800000. So where come from my bootloop.

Is anyone can send me a flashable zip to reset default CPU setting? It's the first time I am using ADB and I probably do something wrong.
[Galaxy Ace II Android Development] fluffi444:
I think that recovery mode set this 800000.

And it looks like that system overwrite our settings again even if we set chmod 444 ?
[Galaxy Ace II Android Development] ace2nutzer:
[MENTION=4962787]fluffi444[/MENTION]

Changing cpu freq on cwm (on-the-fly) works.. but after rebooting the Phone to boot CM11 .. the Kernel is loading again.. with the default settings .. cpu max= 800Mhz .... and the 1300 are really only set during boot... maybe here an sleep command would be better like for init.d scripts.. just to avoid such accidentally fails by user.

To remove only the "keep on boot" for CPU Freq:

Try this:

in cwm:

Mounts and storages

mount /data

mount /sdcard1

in ADB:

cp /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml /sd-ext

or if that not work:

cp /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml /sdcard1

then edit the proper line on your PC and save it back in the Phone..

u'll find this: <boolean name="pref_cpu_set_on_boot" value="true" in the File.

just edit this @<boolean name="pref_cpu_set_on_boot" value="false" and put the file again on same place on sdcard and copy it back in the Phone:

cp /sd-ext/com.android.settings_preferences.xml /data/data/com.android.settings/shared_prefs

or if that not works:

cp /sdcard1/com.android.settings_preferences.xml /data/data/com.android.settings/shared_prefs

EDIT:

And for just in case, set also proper permissions: (after copying back the file in the Phone)

chown system:system /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml

or if that not works:

chown 1000:1000 /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml

and this is also required:

chmod 660 /data/data/com.android.settings/shared_prefs/com.android.settings_preferences.xml

i've done somethig with 1400 mhz...

just reflash kernel, stock cpu freq is 800 so it will boot normaly

that worked for me :)
[Galaxy Ace II Android Development] ace2nutzer:
Nope, that will never work.... :)

The too high freq setted by user is writed on /data partition .. not on /system or directly in kernel .. lol

Also if u format system, flashing CM 11 again and flashing the kernel again the freq is still @ 1300Mhz :)

U need to wipe data ... or just what i explained :o
[Galaxy Ace II Android Development] ace2nutzer:
btw: can pls someone test these 2 builds ??

I need only to know if sdcard is working on both Builds.. or just on V1 or V2 ! Thank u guys... :)

Only for codina - ext4 ! ;)

V1:

http://d-h.st/mAa

V2:

http://d-h.st/UD2H

PS: after testing if sdcard works or not .. u can flash again the latest build: 0207
[Galaxy Ace II Android Development] soko3:
sorry...

i've also checked 'set on boot'

wiped cache and dalvik cache, flashed 20141128 version (only that i had on my phone, i thought it might help) and it reseted freq to 800 mhz...

don't know how, but it worked :eek:

I just wanted to thank you for all the hard work and the effort you have put in making this kernel. Sadly I'm not using my GT-I8160P because I have bought an lg g2. I'll probably give the ace2 to my girlfriend so I'll check in here once in a while to see what's going on. ☺?
[Galaxy Ace II Android Development] aj10:
i am on 02/07, and my app storage decreased from around 140mb to 93mb (i have not installed anything new). i now have a low storage warning.

i tried v1 and v2, and still have the low storage warning, and cannot download anything in the browser or play store due to the insufficient (93mb) storage.
[Galaxy Ace II Android Development] Maev Maxx Damage:
Ace2Nutzer , are there any kernel tweaks on wifi? More power to the chip itself or something similar ? My connection is not as good like it was before , but I am not sure if its something hardware ot on the software side.

And a dumb question again :D should or shouldn't touch anything in novathor settings for the gpu? Now its intouched , like its on default. I use your modded f2fs rom and your latest stable f2fs kernel from 02.07 and I am on dalvik . It drops some frames on beach buggy blitz , but I dont play games , so I want powersave settings. And, of course, thank you for your excelent job !
[Galaxy Ace II Android Development] snyfear:
Indeed, I reflashed codinap_kernel_cm11_20150128_ext4_ace2nutzer.zip and cm-11-20141118-UNOFFICIAL-codinap_ext4.zip and the didn't work, anyway thank you for your help soko3.

Thanks for your help about disabling "keep setting" over ADB ace2nutzer. Unfortunatly I couldn't test it because when I received it, I was already restauring a two weeks old CWM backup and it solved my issue. CPU was back to 1200MHz.

Yes that could help indeed, because when the "keep setting" is enabled it is not automatically unchecked when an higher frequence is selected, that would be a CM request i suppose.

Regarding 20150207 kernel, I would say that I faced several reboots (with 1200MHz frequency) when moving Apps from SD to Phone. I went back to 20150130 which is really stable for me even at 1200Mhz.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah then yes.. if u flash an different kernel with other CPU Steps.. then it'll also restore ack to kernel default... but anyway flashing new rom + same kernel again, will not restore. because the setting is stored in /data.. and it's untouched by the mentioned method.

I ask only it the sdcard work.. if u can install apps when u have enough free space.. not if u can install apps even the sdcard is full.... this is really nonsense post from u :rolleyes:

Not really.. as far i know.. the only tweak i know: set in Router + Phone in wifi settings the Country @ USA instead of Europe ... ;)

I still don't have an answer about the V1 and V2 Build ... if the sdcard / apps problem is present or not ... i need to know this.. then i can improve ram management... Thanks !
