[MENTION=5840412]ace2nutzer[/MENTION], on bbs I have 184 alarms on android with the following description:

Alarms: 184, Intent: android.app.backup.intent.RUN

Any ideia of what is causing soo may wakeups?
[Galaxy Ace II Android Development] soko3:
people usually wipe cache and dalvik cache, and then install zip... ;)
[Galaxy Ace II Android Development] gepel:
This is my 1st post even though i am reader of this forum for a long time. I would like to give thanks on all, especially ace2nutzer, for their hard work. I have a very weird problem and if its possible i'll be thankful if someone can give me a solution. Everything worked fine but after a factory reset, in every reboot in homescreen i lose the icons of the apps that have been moved to sd (there are without any probl in drawer ). I ve tried everything, normal jb and fresh installation of cm, reformat of sd, wipe cache-dalvik , nothing, same result in everyway. Please have in mind that I did not make use of the swap storages or anything like that.. My configuration is CM 18/11 , kernel 2 March and nothing else (except my apps). One last thing, i m using the Trebuchet and not the Nova Lancher but i have the same problem and on Nova too..
[Galaxy Ace II Android Development] ace2nutzer:
@up

this is known issue actually. on some latest builds... just wait for next release... (maybe later) then everything shoukd work fine :)
[Galaxy Ace II Android Development] gepel:
No, the problem is not on missing apps but only in icons on homepage. The icons still exists and apps are running fine on app drawer. I lose the icons only in home screen. The problem is there even with original kernel of 18/11.
[Galaxy Ace II Android Development] ace2nutzer:
If u've that problem also on kernel included on 18/11 .. then it's not kernel Bug... i think u mean the Shourtcout on Home screens ?? If yes, this is Launcher Problem.. try to wipe data of the launcher and format sdcard0 and 1 ....
[Galaxy Ace II Android Development] d.ace2:
This is a well known issue on KK.

code.google.com/p/android/issues/detail?id=63984
[Galaxy Ace II Android Development] gepel:
Yes, but i didn't have this issue before. After a factory reset this problem appears. I tried many solutions ( reinstall of stock jb (uk xxna1, clean install of cm11, format sd0, boot without sd1, trebuchet data clear,without success.
[Galaxy Ace II Android Development] Matteo90:
I think it's a nova launcher bug. Instead of trebuchet, clear nova launcher data and after it asks, don't let it import from a different launcher, but start anew. Hope I could help!

Edit: Now I see that you use trebuchet, instead of nova. Then I have no idea, sorry...

I didn't have problem with launcher because i use Nova launcher, and after first app dissapearing, i restored previous Nova backup and everything is fine..

btw, why are tou people still using Trebuchet? this is first app i uninstall after factory reset..

it's so buggy, useless and have limited personalization
[Galaxy Ace II Android Development] ace2nutzer:
I can confirm this.... very buggy and laggy ... Nova is quite smooth ..... love it :o
[Galaxy Ace II Android Development] MrBlackCore:
Yeah, Nova is totally epic!

Btw, does your kernel work with cm 12, cause I just got another ace 2 and I wanna try cm 12
[Galaxy Ace II Android Development] Ave_Hornet:
This kernel is only for 4.4
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!

Changelog:

20150320:

Fixed disappeared Apps when moved to sdcard with CM

Changed read_ahead_kb 1024 @ 512

Disabled wq_power_efficient_default

Better I/O Performance

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

That Build should work like a charm (i hope so) :o :fingers-crossed:
[Galaxy Ace II Android Development] DusBekas:
The latest version seems working fine.

No more disappeared apps on sd card :good:

[MENTION=5840412]ace2nutzer[/MENTION]

There's still problem with changing minfree values by init.d, like in #978 post.. I guese something must be wrong with permission in kernel.

I tried maany ways, different permissions (in init file and even minfree file), etc., nothing works :mad:

Ps. I had this problem at 3 roms with Your kernel yet.

Beside of that, as always, latest build is even better than previous :)
[Galaxy Ace II Android Development] ace2nutzer:
@up

This is very weird... i'll test this when i've time.. But did u wait at least 30 seconds after boot ??! Because is set a sleep 90 command in init.d files...

But this is only on 18/11 CM 11 .. if u're using other Roms like Carbon etc.. then it's probably that init.d scripts are running without sleep command.

Some changes for kernel parameters needs a sleep command.. because without sleep c. the init.d scripts are executing very fast during boot.. but kernel is not fully bootet or smtg else is also changing parameters and your command is simply overwritten by kernel or framework.

To avoid this, use CM11 from 18/11 or set in ONE init.d script, better the first 00aa just for ex. an "sleep 90" command ;)
[Galaxy Ace II Android Development] ChronoMonochrome:
Afaik, you can just set permission 444 after doing some change, add sleep command and set permission as it was before(644). So the code will look like:

echo *smth* > *sysfs*
chmod 444 *sysfs*
sleep 90
chmod 644 *sysfs*
[Galaxy Ace II Android Development] miryn:
[MENTION=5840412]ace2nutzer[/MENTION]

[MENTION=5695278]ChronoMonochrome[/MENTION]

Finally! Sleep command- that was it.. Thanks :)

Btw. 2D is pretty laggy on latest kernel even with lcd booster.
[Galaxy Ace II Android Development] ace2nutzer:
GR8 ! Wich ROM are u using ? My Kernel is only fully optimized for my modded 18/11 ROM from TeamCanjica !

Are u sure that the new LCD Freq is running ? Check pls here: /sys/kernel/mcde/lcd_clk

u should see 57..... :)
[Galaxy Ace II Android Development] miryn:
I'm using Carbon now, but i must say, after tonight situation with 2d (in 2d games I forgot to mention) is a little bit better lol. But still, it been better. And yeah it is correctly boosted, LCD freq: 57051428
[Galaxy Ace II Android Development] ace2nutzer:
So it's still not really smooth ?!

btw: why u need to change minfree settings ? In latest Build here the Values are IMO good.. that are not the default Values from the ROM .. they are already optimized by me ... :)
[Galaxy Ace II Android Development] miryn:
Yeah, it's not that smooth, as it was on previous builds. The best 2D had some build from february- it was perfect.

About minfree.. I'm experimenting, testing different (@xoen's) values.
[Galaxy Ace II Android Development] zizoumadrid:
i find it 49920000

i think it,s a bit laggy when we move from app to another app

what you recommend in nt-app setting gpu with gaming and without gaming till now i don't understand if we disable auto-boost gpu or not and if we use half speed gpu or not

thank,s for your hard work
[Galaxy Ace II Android Development] ace2nutzer:
Yeah this the default LCD freq... and this is needed to fix the famous blackscreen bug for some Phones with bad LCD Quality.

57Mhz is OC'ed and of course it'S then smoother.

btw: usually it should also work smooth with 50Mhz.. like in GB ... this Bug persist since Stock JB ! I'll try to fix that when i've time ;)

About GPU:

For non-gaming Setup:

Let kernel defaults, and set in NT-APP Mali pre-allocated memory size @ 16MB.

For Gaming-Setup:

Set in NT-APP Mali pre-allocated memory size @ 32MB.

Go to /system/etc/init.d and open the File 01optimization and enable LCD Boost.

Then open the File 01gpu_oc (same folder) and OC the GPU by simply removing one of the "#" .. save and reboot.

Even if u set a too high non-stable GPU Freq u'll have enough time to edit the script after boot.. but only with the CM 11 from 18/11 !

But before u save the file and reboot, it'S really better to copy the command with the new gpu freq and execute this in term. emu. of course without "#" and type "su" before .... ;)

GPU is running in half-speed (200Mhz) only on IDLE ... otherwise it'S always 400MHz and by playing games it's 450Mhz ....

Now it's clearly ? :D
[Galaxy Ace II Android Development] hector_yo:
Some days ago I noticed than I can't switch WIFI On, I updated to 0320 to see if it was a kernel issue related, but i have the same problem... Anyway to test if my Wifi is broken?

---------- Post added at 08:59 PM ---------- Previous post was at 08:17 PM ----------

EDIT: It's a kernel issue, Wifi works on 0302, but it doesn't work on 0311, neither 0320
[Galaxy Ace II Android Development] Alucard:
Thanks!
[Galaxy Ace II Android Development] ace2nutzer:
Nope, Wifi was never broked on this Kernel here.

But Maybe your /system partition is full and the wifi Module can't be installed ...

check free space on /system.. or just delete all Modules and then install latest kernel build again ;)
[Galaxy Ace II Android Development] hector_yo:
Ok, thanks, I'll try it, but..... I think I'll need help with that... :silly:
[Galaxy Ace II Android Development] :
the problem

Hello .

I have a problem because I restore the system as it shows me the '' error while Restoring / system ! '' I have to do in this case ?
[Galaxy Ace II Android Development] [-GuTi-]:
ace2nutzer, last kernel works perfect, gj! :)

One question, will you update you CM11?
[Galaxy Ace II Android Development] zizoumadrid:
yes it's clear now

we can't overclock gpu in nt-app it's that ........ i think nt-app doesn't work to overclock gpu ?

how to check the gpu if he work with 200mhz in idle and work with the value that we set with overclock in gamaing

thank,s a lot for your hard work
[Galaxy Ace II Android Development] ace2nutzer:
format /system in cwm and try again.

Maybe... when i've time for that ;) But yes, u're right, latest kernel seems to work finally without any issue, even ram management is good enough :fingers-crossed:

Yeah i've removed permissions for non working things... i've also removed permissions for dangerous settings... and for some options settings affected to stability and performance i've also removed permission and set the best value already in kernel. But the most of settings are still working on NT-APP .. and it's fail-safe now :) Maybe i'll also update NT-APP...

When CPU is running @ 400Mhz (idle) GPU Freq is half ----> 400/2 = 200Mhz.

u can type in term. emu. "su" then: "cat /sys/kernel/mali/mali_gpu_clock"

to check OC'ed freq: "cat /sys/kernel/mali/mali_boost_high"

Hi;

Can anyone tell me please how many milliamps a phone should use when it is at deep sleep, and when it is at full load?
[Galaxy Ace II Android Development] werindam:
i have so much freezes on latest build :(

usually it happens in apps

hmm..again problem about ram management?
[Galaxy Ace II Android Development] ace2nutzer:
Well, what can i do with this Post ? U should write more infos about CPU / GPU Speed ....

Chrono App installed yes / no .....

Check init.d scripts .... maybe some custom scripts or just some scripts from Chrono Kernel what are not compatible with this Kernel ...

btw: Ram Management is working perfectly for me...
[Galaxy Ace II Android Development] zizoumadrid:
i think for me too .... :rolleyes:

i make fresh install of your rom and kernel without any script just lcd boost with gpu overclocking

my setting : interactive sioplus 400mhz/1.1ghz gpu [MENTION=2670407]500mhz[/MENTION]

when i make some heavy use of facebook , messenger , uc browser ... sometimes i get freeze for 5 to 10 second or more :(

we are here if you need help for test or something like that

we have one goal have a great phone ! thank's a lot for your hard work :)
[Galaxy Ace II Android Development] pablo.see:
My thoughts about latest kernel:

-overall performance and battery life

-from time to time app could freeze system for moment (situation from today: I've barely manage to answer phone call, and after that dialer whose unusable for several minutes)

-if app is freezing or FC, reinstalling app helps

-SMB sharing don't work (try "Samba Filesharing for Android" app from Google Play)
[Galaxy Ace II Android Development] DusBekas:
About max CPU clock, is it related to governor too?

When I use interactive [MENTION=1348102]1200[/MENTION] MHz I had no reboot, but with conservative CPU just running @1150 and lately I had reboot too. So I change to 1100Mhz with conservative, had no reboot.
[Galaxy Ace II Android Development] ace2nutzer:
@up

then it's probably buggy that gov. and what about ONDEMAND ? Can u pls test also ? - Even if it's a bit laggy xD

@ Ram Management

so far i don't have any issue with it, but for some reason for some of u with high usage it's buggy?

U can try to fix the problem by changing the minfree values with that app:

https://play.google.com/store/apps/details?id=com.dustypixels.minfreemanager&hl=en

and post pls here wich following preset is running without any issue!

Quick Guide:

It's very simple: open the app grant root access, and u'll see kernel default minfree values by me... (note don't use the presets, from the App itself they are optimized for old GB!).

Use instead the old presets, the following presets from me:

if u've app freezing due to high multitasking.. (Note a higher preset number here, will have worse multitasking)

use preset 01:

20, 25, 30, 35, 40, 150 -----> Apply and use the Phone.. don't reboot! (after reboot u need to type the Values again and Apply.. but u can set ---> presets ---> save current as custom .. make it easier .. by tap next time "custom" the saved 'Values are back.. then just apply..)

If that didn't help, try preset 02 and so on ..:

20, 25, 30, 35, 40, 200

preset 03:

20, 30, 40, 50, 60, 100

preset 04:

20, 30, 40, 50, 60, 150

preset 05:

20, 30, 40, 50, 60, 200

preset 06:

30, 40, 50, 60, 70, 100

preset 07:

30, 40, 50, 60, 70, 150

preset 08:

30, 40, 50, 60, 70, 200

preset 09:

40, 50, 60, 70, 80, 100

preset 10:

40, 50, 60, 70, 80, 150

preset 11:

40, 50, 60, 70, 80, 200
[Galaxy Ace II Android Development] werindam:
CPU @ 1200mhz / interactive

GPU @ 720mh

Chrono app not installed

Init.d scripts is only from your kernel: 00banner, 01gpu_oc, 01optimization, 90userinit

maybe I should use other minfree values as you wrote.. I try them
[Galaxy Ace II Android Development] MrBlackCore:
Same here and I don't experience any freezes. I use Facebook lite because of the build in messenger and low ram consumption, dolphin browser and moded Skype from a xda dev. 0 freezes + 300mb free ram ( over 40 apps installed )

Plzz [MENTION=5840412]ace2nutzer[/MENTION] i want to install ROM and your kernel with f2fs + art

What should i do ?

Thank's a lot
[Galaxy Ace II Android Development] MrBlackCore:
Take a look at the 2nd post of this thread : how to install 2f2s

To switch from dalvik to art after you install rom + kernel, open the developer options menu in your phone settings and you will find the option to switch.
[Galaxy Ace II Android Development] zizoumadrid:
Thnak's but i want fresh install ROM and kernel f2fs

I don't want to switch from ext4 to f2fs

I don't have any important data on phone i think i don't need to make backup
[Galaxy Ace II Android Development] shaqman89:
You have to switch from ext4 to f2fs if you want to use f2fs kernel
[Galaxy Ace II Android Development] zizoumadrid:
yes i know but i mean i don't want to make conversation i want to install rom f2fs + kernel f2fs
[Galaxy Ace II Android Development] shaqman89:
Actually, the conversion part is still needed. (step 2 below)

If you are using a custom ext4 ROM already, these should be the exact steps:

1. Install f2fs kernel

2. Format data, system and cache partition to f2fs

3. Install f2fs ROM.

So overall, the steps are valid minus the backup and restore part.

Wake-up deny method does not work for me. I have a huge battery drain mostly by "display" and "android os" like same above.

Which gapps do you use? May be battery drain caused by installing pico gapps which (may be) makes google play services run incorrectly, because its broken in some ways?
[Galaxy Ace II Android Development] ace2nutzer:
if u guys think the problem is coming from the gapps itself, then:

in cwm:

format system

install CM11 from 18/11/2014

install pico-uni-gapps

install latest kernel

reboot to system

Download here:

and use the google play services battery drain fix, and report pls if that helped :)

or if that all didn't helped, try again format system and install cm11, install latest pico-uni-gapps and latest kernel .. link for gapps u'll find in CM11 thread from Rox :cowboy:

Hi [MENTION=5840412]ace2nutzer[/MENTION]

I have tested all governor. And and here's the summary:

Ondemand: Max 1200MHz, a little bit slow

Interactive: Max 1200MHz, good

Conservative: Max 110MHz, has a lower clocksped but I think it has a better performace than ondemand

About the vote, it's just my mistake to vote before further testing (I voted 1150MHz).

Thank u very much for testing ! Then i'll remove ondemand and conservative in next release and add 2 custom interactive gov's..

That means u'll have 3 interactive gov's:

interactive- ------> for powersaving

interactive --------> for normal usage, the default one already optimized by me (lagfree)

interactive+ --------> for maximum speed and smoothness

btw: nobody like latest kernel here ? :D - It's working good or not ? And what about the minfree presets what i've posted here some days ago ?

btw2: Till now the max stable CPU Freq is 1250Mhz ... but i've read here sometimes that users have a great Ace2 what can handle 1300Mhz (or more?) stable ... Where are that users ? xD ;) I did the Poll to see what is max. stable.. if 1350 and 1400Mhz is for nobody stable, then i'll remove these useless steps ! :)
