Problems with 3/11 build:

- notifications comes with delay (sms notification, charger disconnect, etc.)

- hard to start heavy resources using apps like Firefox or Maps. Opera GOSMS, Dialer are staring fine

- if heavy app tries to start and screen goes black it's hard to wake up system.

- hard to update apps in google play (very long update time, screen goes black and boom no update)

System using experience is smooth, battery life is OK. Deep sleep also OK.

No move app to sd raport from me. I've didn't installed any test builds.
[Galaxy Ace II Android Development] supachris:
I have also issues with ram management. When I switch from Navigon to other apps (read sms, call...) Navigon is killed and I have to start the navigation again. This is not usable in car. I switched back to 0130. This build works very fine.

Galaxy Ace 2 GT-I8160P, ace2nutzer kernel (20150130) and Rom 20141118), f2fs

Hey, I,m on 01302015 f2fs davik and I've denied google play services keep awake, wake up and auto start. But still "android os" is sucking so much battery.

What else most I do to fix?
[Galaxy Ace II Android Development] pablo.see:
If phone reaches 24-48h battery life, don't mess with system. 3 days is max for idling phone. Another thing, use BetterBatteryStats to check battery drain. Check "Alarms" section.
[Galaxy Ace II Android Development] ace2nutzer:
U guys did u checking from time to time what i write in Post #2 in "Next Version" ? :D

Next build will have max. Multitasking... :)

About Android OS drain: It's a good idea to check BBS .. but don't forget to install it as system app and grant root rights... otherwise it's useless.

For me the fix was: Facebook and messenger (disable all receivers) ... right now checked: Android OS 9% for me....

Hi,

I have strange GPS issues...

GPS hangs somtimes.

After clearing AGPS-data and reloading AGPS-data via gps-tester it works some minutes.

I also manually cleared and modified the data and config as described here some days ago.

Additionally it spend a lot of time to get a gps-lock because the input gain is too low.

For example: i stood three days ago on a 1700m mountain without any clouds and had a lock after 15 mins with a poor location range: 200 m off the right position.

On earlier kernels about 1/2 year ago I havent had this problems.

Its really frustrating for searching geocaches ...

Bye ... Peedy

Here are my logs. Could anyone analyze my logs and tell me what drain my battery. I charged my mobile and l didn't touch it whole day. I checked it few minutes ago and I found battery on 5%!

Thanks for help.
[Galaxy Ace II Android Development] pablo.see:
Do You use 2G only? 3G drains battery much more than 2G.
[Galaxy Ace II Android Development] ace2nutzer:
Google Play Services.

but if 3G has better Signal quality than 2G, then it's better to use 3G ... (bad Signal consumes the most power, and even more if the Phone must switch very often between 2G/3G !)
[Galaxy Ace II Android Development] soko3:
2g+3g drains too much battery... i always used just 3g and my battery was perfect until i installed messenger and flashed 20150215 version...
[Galaxy Ace II Android Development] r_e_n_e:
Ok thanks. I installed Advance task killer, so I will see if it helps. I live in the city and I have strong 3G signal here. All day I'm using WiFi connection anyway...
[Galaxy Ace II Android Development] soko3:
task killer will just make mess and makemore drain

when he kills an application, app restarts and it uses cpu [MENTION=218088]Max[/MENTION] frequency to load it back to ram... so task killers are useless..
[Galaxy Ace II Android Development] r_e_n_e:
So what do you recommend? I expected that actual CM what I have is smooth... :S
[Galaxy Ace II Android Development] gothicVI:
Try greenify
[Galaxy Ace II Android Development] matthias1976:
maybe ur battery is broken !?

looks realy strange. the phone was in deppsleep the whole day. much too high lost of battry for this.

or maybe the percentage table mV/% iss messed up !?

i cant help u, sorry.

other battery to test ?

test other ROM/Kernel combination see if it help

Below is my BBS alarms section.

What to do to fix it? [emoji20]
[Galaxy Ace II Android Development] ace2nutzer:
:good:

nothing.. Android has already internal "Task Killer" when ram is full, Android beginn automatically to kill Apps.

But as i said: Google Play services.. see:

Alarms: 403, Intent: com.google.android.intent.action.MCS_HEARTBEAT

and: (Viber?)

Alarms: 198, Intent: com.viber.voip.action.KEEP_ALIVE_RECEIVE

But i'm also believe your Battery is slowly death.

Same **** :highfive:

Greenify is causing strange bug

every time it hibernates apps, xposed framework uses several extra MB on /data... after half day of using, xposed framework is using about 200-250 MBs and any other app cant be instaled due to insufficient memory...

i needed to delete greenify, delete xposed framework and install it again to fix that...

my experiences with greenify are mostly bad...

so, [MENTION=5895297]gothicVI[/MENTION] , avoid it if you can ;)

EDIT: just to mention, i am talking about donate version which is needed to hibernate system batery-eater apps
[Galaxy Ace II Android Development] gothicVI:
[MENTION=5840412]ace2nutzer[/MENTION] & [MENTION=5737671]soko3[/MENTION]:

My experiences with greenify are good. I don't get this strange behaviour :what:

Yet the way greenify works is completely different from the way a taskkiller works. Keep this in mind ;)
[Galaxy Ace II Android Development] ace2nutzer:
Can u tell me how it works and wich apps do u greenify ?
[Galaxy Ace II Android Development] gothicVI:
From my understanding - please consider consulting the original thread for detailed information - greenify does not only clear the ram or kill the process as taskkiller or cleanmaster does but hybernates the app/process/service in order to prevent automated restart.

From my personal experience this works quite well as greenifyed apps dont't show up as runnig.

Apps I greenify are e.g. galery, xda, my browser, 9gag etc. Actually all apps except from system relevant ones and email, sms, fbmanager, hence the ones I need to be running in background for communication purpose ;)
[Galaxy Ace II Android Development] fluffi444:
Ace2nutzer was never fond of greenify, istn't it Ace2N? :)

But I like it and proved the advantages for my phone in particular.

I suggest not to use it blindly - I suggest to try it - If you have tons of stuff (as I have) its usefull... Try it one week with - and one week without...

But if you are running your phone with only a few apps (only GAPPS + Whatsapp for instance) - its really not needed!
[Galaxy Ace II Android Development] ace2nutzer:
Thx for good explanation.

Yeah this is what i mean.. Apps like FB, Messenger, WhatsApp, Email etc.. must running in Background as active .. otherwise we'll never receive a instant message... that's why i'll never understand the sense of Greenify.

And that Apps u've greenify'ed like Gallery etc.. should run as usualy in ram.. as "cache" but not "active" and even if these apps are marked as active in RAM .. i don't believe that they can cause some CPU Load.... I Think that will only slow down the system and drain more battery as soko3 said.

[MENTION=4962787]fluffi444[/MENTION], I've tested greenify for 1/2 Day.. (the free Version) and i don't see any improvements with that.. just faced that greenifyed App needs longer time to start, then i was frustated and i've uninstall it xD

Therefore, to check if one app is causing cpu load after the App was closed in a normal way with the Back-Button, just check actually CPU freq... if the actually CPU freq will stay on min freq.. then there is nothing to fix, hibernate or something else !

But for such Problems i type simply in terminal emulator: "top" and with that is very simply to see wich app is causing the most CPU Load... then i check what is causing that high load.. and if i can't fix that.. or i don't need that app, then i uninstall that .. and i'm done :) ;)
[Galaxy Ace II Android Development] fluffi444:
That's what I said...Test it a week... 1/2 day with hope that everything works faster/better/or whatever is not enough...

Main goal is to keep RAM free and prevent apps from unwanted behavior... And we all know that Andriod "normaly" should do the "RAM Job" by itself - But on our small RAM devices it didn't work as good as it should if we are running apps using more RAM...
[Galaxy Ace II Android Development] ace2nutzer:
Well, then we can maybe have the same result by using different minfree Values to keep more ram free.. if that is the main goal...

I've tested different minfree values here on releases .. some for much free ram and some for max. multitasking...

With max. multitasking users are complaining about bad speed... and with much free ram the Problem is bad multitasking...

btw: In next build i've updated the minfree values..... i hope that values are good for all... it have max. Multitasking.. but it'll not use the full ram in all cases.. to prevent bad response.
[Galaxy Ace II Android Development] gothicVI:
You're welcome :)

Actually you only have to start greenify once, specify whitch apps to hybernate, then create a shortcut and use this to hybernate the apps selected before :p

This is totally true. I got a lot of apps installed (SZ, Zeit, tagesschau and other news and forum apps) and these don't need to run unless I open them :cool:

Nevertheless greenify got me some huge improvement in battery life but [MENTION=5840412]ace2nutzer[/MENTION]'s way using top does the job as well but not as comfortable - in my oppinion :p

Try bln contol free from playstore.

Over ADB also working. Dont know commands.
[Galaxy Ace II Android Development] doctormord:
Power off trigger at the dead end of battery should be raised. I have noticed a hard shut off while being on 4% rest-charge. The other day, the battery was so flat, that screen and buttons started to flicker.

So either change the percent-labels or cutoff voltage to prevent fs-corruption due to hard power-down-reset.(Using 1101-p1)

Regards,

[Galaxy Ace II Android Development] ace2nutzer:
Yeah.. i know that.. It's not simply.. the Voltage included poweroff voltage .. all is right.. but anyway.. the phone make his own life ^^ Next Build is hopefully much better.. it have many fixes...

Please remove the 4.4.x ODIN version. I can't flash it because it's stucked at SMDDownload, after lots of minutes it says "failed".
[Galaxy Ace II Android Development] MarquesYOLO:

200MHz works well here, but I think the active power consumption is sligthly higher as CM11 kernel. I use interractive gov.

[Galaxy Ace II Android Development] Andrewbons:
What do you mean "NT App stable if we don't UV"? I usually stay with -100mv for both CPU and GPU, with no reboots. Should i stay that way or is better to reset to 0 UV?
[Galaxy Ace II Android Development] ace2nutzer:
U can do what u like.. but as i said: if u have reboots then set CPU GPU @ 0.0mV and reboot.

Also the UV Algorithm is not adapted for the new (stable) Voltages !

I'm actually very busy....
[Galaxy Ace II Android Development] MarquesYOLO:
Charge complet, is good battery consumption, but I remember I had about 3 hours of screen with some rox builds. Good work. (interactive + noop 800-200)
[Galaxy Ace II Android Development] ChronoMonochrome:
Have anyone tested vape_50_opp @ 0x18 (or values around of this) ? As I have seen, you also increased 100_opp voltages - but they were already overvolted (since 1V - 0x18 is standard mali voltage). I have a theory, that blank screen is caused only by too low vape_50opp voltage - as it can be seen, some codinas has vape_50_opp @ 0x14, and this probably is enough for ws2401 driver, but for some reason isn't for s6d. If so, another changes like overvolting mali or forcing ape_100 should be really unneeded. I've already done so much *hardcoded* changes, but didn't test it yet. Maybe there's enough to set 1V for vape_50opp?
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for Screenshots.. that's really bad !! I never had some badly Results...

Anyway, with your System is something not OK.. Compare my Screenshots with yours.. u have nearly the same percentage for Screen ON and Android OS .. I suggest to check with BetterBatteryStats what drain so much the Battery. :cowboy:

Nooo,

Default Voltages according to my AVS:

For CPU 800Mhz: 0x26

For GPU 400Mhz: 0x24

APE 50 Vape = 0x18

I use only Vape 0x18 for LPA.. and I've no Problems...

But u remember the Test with [MENTION=4962787]fluffi444[/MENTION] .. his ape 50 is 0x14 ... and didn't work @ Audio... Therefore this is really useless Value from AVS... If I remember correct, fluffi444 have ws24 Driver ;)

I've already released an Build with everything Stock but only 0x18 for LPA... and [MENTION=5210243]exodius48[/MENTION] reported me Blackscreen issue even on CWM ! - Since I've even disabled the LPA, exodius48 never had an Issue !

And even if 0x18 where OK for LPA or screen OFF-- it makes anyway an conflict with the GPU OC Driver.. because for ex. 700Mhz GPU / 2 = 350 Mhz on 0x18 vape it's not really stable :) < ------ even with static GPU Clock, because APE 50 OPP is = GPU / 2 !!

On my actually Kernel is nearly nothing overvolted .. just the OC Freq.. for more stability..

Also i didn't force APE to run it @ 100% all the time.

It runs this way:

Screen OFF:

DDR 25%; APE 50%

Screen ON:

CPU FREQ: 300Mhz - 1Ghz +:

DDR: 100; APE: 100;

CPU FREQ: 100Mhz - 200Mhz:

DDR: 50%; APE: 50%

Vape in all cases @ APE 100 OPP Vape.

The marked Values in Green are on Screen ON :highfive:

I'll try to generate an "universal" Voltage Table for CPU / GPU according to the AVS Files.. from 20 Phones.. i think that's is enough and 100% stable for all.

Another Thing:

Even if we find an stable APE OPP 50 Voltage for all users.. u can't set this Value in Kernel, because isn't stable with the included APE 25_50%_partially Things....
[Galaxy Ace II Android Development] faroukovic3:
Please can someone tell me how to install a kernel and what is the benifits from it and If I install it can i use the 1250 cpu oc step with no random restart or battery drain and how the installation can be canceled ?? thnx I always try roms and tweaks but i never install a kernel

:o:confused:
[Galaxy Ace II Android Development] Andrewbons:
Same for me, since your first release i have more batter consumption than chronokernel. Wakelocks are ok, already checked.

About black screen, it happened once while using my phone. Didn't checked on CWM, i don't care anymore if it boots at first attempt or i have to wait 10 minutes
[Galaxy Ace II Android Development] ace2nutzer:
Really ?! U installed already an kernel every time u did flash a ROM ! The Kernel is included in the ROM...

Anyway, to install this Kernel:

Flash one 4.4x Rom then flash this kernel like a ROM ..

That's it !

To remove this kernel:

Flah an other kernel, or flash other ROM.. - simply ;)

u Guys @ Battery drains.. pls post for a minimum an landscape screenshot from the org. Battery stats from Android.. i mean this with the Graph.. !! And post wich Kernel Version do u use....
[Galaxy Ace II Android Development] faroukovic3:
what is the most stable cpu step and governor plzz I'm on interactive 1000 Mhz now but I want a higher step without random reboots Thnx
[Galaxy Ace II Android Development] ace2nutzer:
i forgot to mention: BBS ... and if u don't like that some non system apps should start automatically after boot, then u can simply disable their receivers with autorunmanager ;) - I like professional ways .. there is really no need to use that app.

This is the same if u're using Software Firewall on your PC .. and let the Hardware firewall in the router disabled what is far better ... :o:D

EDIT: Another thing: many apps (the free versions) have Adds, i mean showing apps when the Phone is online .. that drains also much battery ... i've many such apps with adds .. but these apps can run also without internet connection... for such apps i use a firewall to denied internet for some apps.. then adds are gone.... that saves also much battery.... and so on ... there are really many ways how to optimize an android system... but definitely not with a noob app like greenify (sorry ;) ) I need also to mention that Greenify itself cause also CPU load when it's working and waste also some normally useful RAM ... Keep this also in mind guys ;)

[Galaxy Ace II Android Development] Bito21:

And what setings do you use on Android manager, because i cannot disable more than 10...
[Galaxy Ace II Android Development] ace2nutzer:
I use the Firewall from Avast... this:

[Galaxy Ace II Android Development] [-GuTi-]:

Do between the steps alway wipe data, and format also sdcard0 and 1 as vfat in cwm.

@ all

after my whatsapp version was to old and it won't work anymore due to ART issue, i've extracted it from an other ace2 with CM11 with dalvik the latest whatsapp version ! .. just replace the .apk with the old .. reboot and enjoy... don't worry about FC.. after second reboot whatsapp works fine again with ART :D

Since I am using Link2SD with ext2-Partition on external sdcard I'd like to share my experiences with the following builds (ext4 version not f2fs):

20150311 : everything(!) works ok. Just one hint: Installed your zip, cleared cache and dalvik cache. After first restart not all apps were shown until I restarted my launcher (or rebooted). So no big deal.

20150318 : strange thing: some moved apps are missing - some not (68 shown from at least 132). After a closer look it seems that all apps on 2nd partition on external sdcard are fine but all apps on internal sdcard (app2sd) are missing ...

=> switched back to 20150311

PS: Thank you for your hard work!

PS2: greenify is also useful for apps keeping my phone away from deep sleep (like an app created by formel1.de). So after I read everything I greenify this app.
[Galaxy Ace II Android Development] ace2nutzer:
Yes i know.. it's not really needed, but for linux are also existing some viruses.. .. but i don't have it installed due to the Antivirus.. this app have nice/useful features like: scanning SMS for bad commands, also Web browser addresses, Anti-Theft, Great Firewall.

And i've configured it that the virus scan did only scans new installed app for one time.. and then the scan do nothing... no scans by read/write ... just to avoid useless CPU load.

Yes i know that dude ;) Already fixed :o Update as soon i can ... :cowboy:
