I have question for your people.

Which frequency you use in your ace 2 on cm11?

I now use 1.2ghz.

I little over clock because ace 2 is my last working phone.

****ing bricked HTC Desire 310.

How many your ace 2 work on this frequency?

My on 800mhz max work 3,5h on battery.

[MENTION=5840412]ace2nutzer[/MENTION] thank you for your work, but I need your help again because I've got a problem with black screen in recovery (after installing kernel). I'm not sure what type of LCD do I have, but I think it was S6D27A1
[Galaxy Ace II Android Development] ace2nutzer:
It's here:

http://www.xda.mister-freeze.eu/XDA-files/ace2nutzer/GT-I8160/General/

As for recovery black screen: i need to know the LCD Type. U can check this with Kernel Control App.

If it's still locked, u can also use terminal emulator or ADB ... and type command:

cat sys/kernel/mcde/lcd_clk

U've to enable "Use zRam" in Kernel Control APP.

Check the Poll here ... as u can see the most stable freq is 1200Mhz.

@ ALL

somebody want to have "High Performance" Profile in Kernel Control APP ?

With this setup:

CPU: 150 - 1200Mhz

GPU: 250 - 600Mhz
[Galaxy Ace II Android Development] Kurajmo:
Any option to manipulate cpu and gpu without A2N app?

For now I don't have free money on Google account to buy this app.

Cpu oc i changed with no frills app.

But I don't know with what I can change gpu clock
[Galaxy Ace II Android Development] ace2nutzer:
@up

u don't need to use CPU frills for CPU OC ... u just can OC CPU in Seetings ---> performance ----> CPU

GPU OC: u can use init.d script ... but it's kinda annoying job if u want to edit the freq a few times.

Another way: u can also use CM Perf. profile .... just add performance profile to your Quick settings ... then u can use 3 power modes and switch between those profile with a single tap !

btw: u can pay the app also with the money from your SIM Card or SIM Provider ...

btw2: it's only 4,39 PLN if u're living in Poland .. which correspond approx only 1 € !
[Galaxy Ace II Android Development] Kurajmo:
Yeah I know I can see price. But unfortunately now I only have 50 groszy on my Google account. Can't buy anything. Bad luck chase me now. Maybe in next month I buy this Google play reload card. I don't have contract with my provider (Orange). Then I can't pay with sim card. I use prepaid sim card.

I try search for other gpu changing app.

Anyway thanks for help

Finally I managed to install the ROM (with sd-card only repartition).

First day - phone works great, no problems, a lot of space for apps (3GB for apps is HUGE).

The observation of my phone continues. [MENTION=5840412]ace2nutzer[/MENTION] thank you again for your great work

I am using 1150 MHz CPU frequency, in my case 1200 MHz is unstable.

By the way, what GPU overclocking frequency are you using?
[Galaxy Ace II Android Development] Kurajmo:
Me? I don't use any gpu oc. For now.

Cause yesterday I fix Desire 310.

Now ace 2 may finally rest. I use this phone for music, Web stuff only now.

For games I use HTC.

You know Mali mp2 is better than old Mali mp

I don't know how. But i spend almost 6 hour try to fix this phone.

And here's result. Phone work very good on cm13

But today I use ace 2 little.

Music and WiFi file transfer.

I notice my music little lag. And one time ace 2 stop work completely. Phone just shut down itself I needed turn on ace 2 again with power button. I use performance profile. No gpu oc etc. Cpu 1200 oc only.

Strange. But happen. I don't know why.

Too much oc or something more?
[Galaxy Ace II Android Development] shaqman89:
Most likely that your device is unstable with 1200. Try to use 1150 or 1100 and see if it still happens.

blurry/double text under 50% brightness

ey guys, hoping ill get some help. my LCD type is S6D IIRC

i recently switched from stock partition 718 to repart 323 and im having the same LCD issue that was fixed with an addon flash named 'ace2nutzer.kernel.4.4.x_20160719_LCD.FIX_codina.p.l'. the jellybean kernel also had this. will flashing this over the 323 rom and 426 fix it?

also a small issue, my phone is now a P version. im 100% its a standard non P/L. hopefully it wont cause too much of an issue.

i followed all of the steps from odining the nf2 all the way to clean installing the rom and kernel.

update

after 2 days of use, its still here even on full brightness. screenshotting is normal and not blurry.

more update

it just fixed itself after a few minutes of use? well i did just wake up (i wear glasses, but i can use my phone fine without), did my usual routine, came back after coffee and cig to finish replying messages, and its back to normal.
[Galaxy Ace II Android Development] Farzin 073:
Just use latest kernel and in a2n kernel app turn on chuck norris mod ...
[Galaxy Ace II Android Development] ace2nutzer:
Not an problem, as long u flash the proper rom according to the right model u see when u turn on the Ace 2 (cold boot)

This Problem sometimes happen when the Phone is cold.

Anyway, it can also happen if u did enable the option "Tuned Freq" in A2N Kernel Control app.

So try to disable it, if doesn't help much, then enable "Chuck Norris mode" like Farzin said.
[Galaxy Ace II Android Development] fonzacus:
ah, havent bought the kernel app yet. it does seem to come and go on its own after it wakes up from deep sleep. after around 5 minutes it disappears for a good amount of time.

any plans on releasing a fix for it like a while back?
[Galaxy Ace II Android Development] Farzin 073:
This problem disappear when phone get warm.

U have 2 ways

Hard way is .. warming phone be4 use .. and its temporary .

Easy way is buy kernel app and solve it forever :)

---------- Post added at 06:43 PM ---------- Previous post was at 06:36 PM ----------

@ace2nutzer

Can u make a new repartion with increased system partion ?? I need system with about 700mb.

Maybe u could use TMP partion .. its useless i think because whenever i check , about 300 mb of that partion was free . if u do this You will do a great favor to me :);)/)

[MENTION=5840412]ace2nutzer[/MENTION] The camera writes the wrong date in exif.

I'm using the default camera app
[Galaxy Ace II Android Development] lace_hvc:
I upgraded to the latest ROM and kernel. Dirty installation. No repartitioning at all.

Everything is fine so far except that file manager is missing.

Purchasing your app anyway now :) Thanks for all the work!
[Galaxy Ace II Android Development] fonzacus:
thanks for the replies farzin and a2n. just bought the app for the show of support.

id suggest updating the OP in case other users are shocked like me. what i found most shocking was when after flashing the repartition and going into recovery mode, it said 'cant mount system' and a bunch of other stuff.

do you have a flashable stock partition? it seems your reparts are compatible with other roms too. its also nice you included cwm as well as a long time ago you seperated kernel and recovery.
[Galaxy Ace II Android Development] Przemas11:
If you want to have default partitions I can recommend installing default 3 part JB using Odin. The second option is to flash proper repartition file that I don't have.
[Galaxy Ace II Android Development] AkosPaha:
Hello Ace2Nutzer!

Is there an Android Security Patch Update?
[Galaxy Ace II Android Development] ace2nutzer:
:good: :highfive:

Will do, it's just normal, that they can't be mounted after flashing the repart script, because nothing is formatted.

But after formatting, everything can be mounted normally again.

For which reason u want it ?? There is really no reason for the use of stock partition layout.

There are already 2 optimized partition layout, one for the use with sdcard, and the other one for the use with or without sdcard so that there is also a possibility to use the phone also without sdcard and having more space for apps and some space for real sdcard0 .

Check Post #3 for more informations about the resulting spaces after the repartition for the 2 different scripts.

If u need other layouts, so your own layouts to your needs, u can check the whole thread from [MENTION=5695278]ChronoMonochrome[/MENTION] about CWM repartition .... there are a lot of different layouts posted ... (requests from users) ... so just check it, and pick one that fits your needs ... it's the same script like mine.

Another way, unpack it, modify the script like u want, save, re-pack and flash it.

OF course, first try to understand how it works, then edit.

As long u only change the size for DATA, SYSTEM, CACHE and UMS ... (sdcard0) nothing can happen, i mean u can't brick your phone.

Yes, it was only a messy solution. I wanted to give support for other recoverys ... but i had to abandon that project, due of very strange unsolved issues with the other recoverys.

Probably not, anyway i've re-sync'ed cm11 sources for just in case we don't miss any patches, and i'll recompile it with some new optimizations for better performance. - Release maybe this weekend, all updated, rom, kernel, app.

Why ?? - with latest repart and installed smallest gapps, i've 119.5M free ... and this is reserved free space for gapps updates. (yes gapps package, is always a bit bigger after an update - new version)

300mb ?? do u mean /dev ?? that's normal .. and is a virtual filesystem in ram.

Nope, it's not missing ... check if the app is there at all on /System/app/CMFileManager.apk

If it's there, wipe data of that app, and then reboot to cwm and wipe dalvik cache.

Yeah and thanks also for the Support !

No.

I'll try to fix it !
[Galaxy Ace II Android Development] lace_hvc:
The file manager apk was missing in the ROM. I must have deleted it accidentally. Usually I always remove some apk from the ROM before installing it. Oops... :)
[Galaxy Ace II Android Development] Farzin 073:
I want that repartion for my other ace2 . I use cm13 on that one and it requre more system spase about 700mb and other repartions is less than yours .

Tanx for your support ?

P.s : do u tend to start another project like cm 14 ???
[Galaxy Ace II Android Development] Culateralligator:
I've always used this zip when I had CM13:

[Galaxy Ace II Android Development] Farzin 073:
Sounds good . Tanx. Just a quistion I have reparted befor with ace2nutzer script , so just flash this new script and format partions or won't need format again ??
[Galaxy Ace II Android Development] ace2nutzer:
I don't know right now. - It depends on the amount of free time.

after changing the partitions layout, formatting everything is always needed.
[Galaxy Ace II Android Development] Przemas11:
I noticed a problem with screen (both with Chuck Norris mode on and off).

After a long phone call the screen is black and it can't display anything (reboot helps).

It happened three times and I don't know if it is a problem with my phone or with the ROM.

I think that there might be a problem with proximity sensor (or something connected to that).
[Galaxy Ace II Android Development] ace2nutzer:
Wait for ROM Update, if it'll not help, then it's proximity sensor bad circuit.

Release is planned in around 24 hours, of course like always if everything goes well :)
[Galaxy Ace II Android Development] Yønn:
I had a similar problem.

Sometimes I get Black Screen and I cannot get display by pushing Home Button although Backlight gets on. In that case I have to reboot t use the phone again. But still, CM logo bootloop happens sometimes.

I have latest nosdcard kernel/ROM and link2sd app. Since I removed some useless files from SD card, things are better. Nevertheless, I still get such freezes from time to time.
[Galaxy Ace II Android Development] Kurajmo:
Interesting. Another creepy Ace 2 screen bug?

Like black screen in CWM?

I don't see anything like this around 3 months.

When i sell my previous Ace 2 with this issue.

What is your LCD type if i may ask?
[Galaxy Ace II Android Development] ace2nutzer:
Yes it depends also on LCD Quality .. not only the Driver.

But it seems that even such difficult LCD's, i can make them to work with some tricks in the driver.

Such tricks (fixes) are included in the Button: "Chuck norris mode"

But actually there is only a fix for LCD Type S6D .. so if u've LCD issues like u see that only the backlight gets ON .. and nothing else. ... then make a Photo, post it here, and write the LCD Type u've.

Then i can try to add some workarounds to the Chuck Norris mode.

No need to quote or mention me, i check my threads every day ;)

@ ALL

Rom & Kernel Release maybe need some days ... I'm reworking memory management in order to make it full stable system. (if it's possible to fix)

Anyway, that bug is probably present on all android devices. :eek:
[Galaxy Ace II Android Development] msq2:
Good idea, it would be cool if there was no need to restart every 24 hours because the free ram after closing all applications with high uptime is 50-150mb

thanks :)
[Galaxy Ace II Android Development] Kurajmo:
Eee? Did I miss something?

I always have around 280/300 MB free ram. When I stop playing heavy games like ygo link.

Use heavy app like messenger.

For me rebuild rom or kernel isn't needed.

This phone is little slow cause lack of ram. We can't change that.

But Ace 2 is faster mid range phone what i used in years.

This phone is like Galaxy Core + for me faster.

But isn't perfect.

I recommend use Ace 2 for calling, video, little web browsing with Opera mini, puffin browser. Nothing more.

If you want play games etc. Just buy new phone with 1gb or more ram. Stock Android 6.0 and 4 core procesor minimum.
[Galaxy Ace II Android Development] ace2nutzer:
This isn't the problem. The System is only efficient when ram is almost always full ... of course not always 100% filled ram. But Having 64 - 128mb free ram is probably the right way.

The Problem is actually memory overcommitment ;)

So far checked up to Galaxy S5 and there is also memory overcommitment enabled. (like on ace 2)

And Probably the same even on newest S8.

Just for Fun, i've tested what happens when Linux is running with mem overcommitment (like on Android) when compiling a ROM ... and after the rom was compiled, the system wasn't anymore responsive and it was partially broken even with a lot of free RAM... and i had to reboot to fix all issues. The same is on Ace 2.

Normal behavior after closing an big app.

So u don't need a faster ROM and kernel ? :D

That's right, RAM is the biggest problem here.

But the second bigger problem is the ram management.

Of course an Android Phone with more RAM than on Ace 2 will work better.

But it has the same problem like on Ace 2.

The Thing is, if u can run i.e. 7 apps on Ace 2 till it runs out of memory .... then u can run 10 apps on a device with 1GB RAM til it'll run ALSO out of memory.

That means it just needs more time or more stress to run out of memory, but it'll not fix the main problem of bad memory management.

So lets hope i'll find a good way. If so, reboot is never needed .. even not after one year of uptime :)

For more informations about memory overcommitment, read this Blog, which is very easy to understand:

https://www.etalabs.net/overcommit.html

This was my motivation :o

And now i understand why Linux works better than Android ... damn it!
[Galaxy Ace II Android Development] Kurajmo:
Nope I just say. We can't force Ace 2 working faster more than is now.

Old hardware. Sad but true.

You developers are magician with custom roms etc. But you are not immortal and can't jump hardware fance limitation.

But still i respect all of you.

My fun with Android custom roms start in 2011. Before that i moded some Sony Ericsson like k700, k550

And some Nokia on Symbian phone too.

You people do really hard thinking job.

My wish is one day some GSM company hire good Android developers from XDA.

Like you ace2nutzer.

Anyway.

If you say you can force old Ace 2 to more performance. I trust you.

And watch closely what you can do to this phone.

OK now im going to sleep. It's night in my Country.

Have a nice day. Greetings

What about the zram? I know that you set swappiness=0 but I think that zram could consume some of internal memory, don't it? And without deodexed ROM I can't do something like... (Sorry I don't remember ;))

---------- Post added at 06:46 AM ---------- Previous post was at 06:41 AM ----------

And about CPU, running at 1300MHz will reboot the phone:confused:. 1200MHz and 1250MHz will make the phone unstable. I think 1100 and 1150MHz is the most stable CPU speed. You should remove 1300MHz to make sure thay people don't accidently touch it :) 1200 and 1250MHz is helpful when charging:victory:

Xposed is working here :)

I will report any errors experienced when I use this ROM [MENTION=5840412]ace2nutzer[/MENTION].

---------- Post added at 06:58 AM ---------- Previous post was at 06:47 AM ----------

List of errors experienced:

- Switching to libart.so will soft brick the phone

- SIM card contacts cannot be read

- Serial number is 0123456789ABCDEF

- Change swappiness to any value will hard reboot the phone after some minutes (and then auto be changed to 0)

[Will still be updated]

no auto deepsleep

anyone else having insane battery usage? after a week of using 323+426 ive been having lots of issues. back on 718 i wasnt having high usage. im usually gappsless but when having it on things worked just fine, i usually freeze it renaming it .apk0 and rebooting.

recently decided to reinstall better battery stats (BBS) and took a look around and it said the phone wasnt redeepsleeping after a notification (awake screen off). greenify that usually does wonders was powerless when facing this.
[Galaxy Ace II Android Development] avix213:
long ago i had feeling that when the BLN blinking light was on after notification it was draining battery so i turn off BLN and forgot about it but maybe there is some issue
[Galaxy Ace II Android Development] ace2nutzer:
yes it was, but on coming kernel it's default = 60 .. and with an setting in Kernel Control app it's = 100.

Wait for update.

Yes, but it doesn't mean if u've 150mb zram = 150mb real ram consumed... at first all of the physical ram is used ... then if the system need more ram (and oom killer can't do nothing) then it starts to compress 150mb of ram ... that's it. But yes, there is also some memory usage when zram is allocated and not used at all ... that's right ... but it's very low ... maybe 32kb.

It's already that way that u can use theming and so on. it's already right for modding ;)

High freqs are in 50Mhz steps for a reason ... also the 1300mhz step is only added for testing purposes .. and to help and decide what max cpu freq is safe to use.

If it seem that 1150Mhz is max stable ... (like my phone) than i suggest to use max. 1100Mhz if u want to OC.

So in other words: find out the max stable freq, that worked stable for the whole day ... then remove 50Mhz ... and that's your 100% stable CPU freq.

Using the max. possible stable freq is just too risky to run the system with potential miscalculations !

Nope, it needed to decide if it's safe to use 1250Mhz Step. That means, only use 1250Mhz Step if the phone was running stable for one day @ 1300Mhz.

I know that's a very rare case ... but if u search the thread u'll find approx 2 users where 1300Mhz worked stable ... maybe not 100% stable but it was possible to use the phone at such high freq for some hours till some apps FC ...

And if see the poll here ... u can see that for most of users 1200Mhz is max stable .... while 1250Mhz are only a few users .... at least for those who voted at all !

But the Voters for 1300Mhz - 1400Mhz are likely fake voters :)

Or helpful if u'll replace old battery with new one ;)

Using the Phone with hard OC with old battery isn't very useful :)

Yes.

Wait for next update, anyway when u switch to ART u need to make sure to have a lot of free space on /data ....

So repartitioning here for sdcard only is really needed.

Yes, this is bug is present on all custom ROM's for the Ace 2.

The Ace 2 was never an official Supported Phone for Cyanogenmod ... u can be happy that it works at all ;)

Yes, this intended and needed as an workaround to satisfy some apps that need this serial number.

Other than that, it serves nothing.

Never heard about this Problem. How are u trying to change it, and what values are u trying to set ??

Checked the logs and screenshots. u've to check "Partial Wakelocks" which app was causing to keep the phone awake.

It seems that CPU freq stuck at 800Mhz ... if u'll face again this problem, then check cpu freq ... it should cool down to 150Mhz ... if not, then open terminal emulator and type: "top" .. then on the top of the list, u'll see on first place the process with the highest CPU % usage ... that's the app that cause the problems :)

If u had enabled BLN Wakelock on Kernel Control, then it's normal that the phone stay awake during blinking.

Yeah, thank you :o

Thanks ! Have a nice day too !
[Galaxy Ace II Android Development] fonzacus:
i usually disable BLN via normal settings under display, lucky with this rom and kernel i dont need to play around with the kernel app. all i have active is the chuck norris mode.

yeah just realized that most of the time it was at 800mhz. that was pretty scary. just for test runs this week, i plug in my phone before sleep, unplug, and tried to find what drains it. i only have network for phone and text only while i sleep. the BBS showed it was android os IIRC, i just dont remember which wakelock/alarm it was. like in the other battery screenshots all of them were reset just before going to sleep. android os keeps topping the charts.

the cause was my operatora sms that came while i was asleep. normally under 718, that wouldnt cause the 'awake (screen on)' and kernel wakelock 'suspend backoff'.

on this attempt, what should i focus on?
[Galaxy Ace II Android Development] ace2nutzer:
As i said, try to find out which app hold the cpu @ 800mhz.. and after the screen is a few hours off, then check in BBS the "Partial wakelocks" .. there u'll see which app it the culprit. But i'll keep an eye on "suspend backoff"

Of course this only works, when the phone is not plugged in for charging.
