again and again ... it not java problems .. or problems with the apps itself .. as i said it's a matter of native Device drivers .... so u can install 1000 apps for camera .. no one will work ...

another example:

if u don't have proper audio driver installed on your computer .. then u can't hear some audio at all ... ;)

Coming Build will fix maybe maps FC ...

and next build... will fix maybe video-rec, live stream and maps FC if it was not fixed previously... ....

but as always i can't promise of 100% .. that's why i say "maybe"
[Galaxy Ace II Android Development] Dr360r:
With camera app, make as many photos as you wish. You'll be fine, whether you store it in sd or internal memory. As soon as you make a video, app starts crashing everytime you turn it on. To fix it, delete the video and you can use camera app again. Or move it out of the storage directory, and camera app will start working again.
[Galaxy Ace II Android Development] IAmLucky:
yes we now know it is not java errors, but how could we say it? java errors is easier to say than 'seems like native device drivers giving us crashes' JK :D

I will try to flash next coming ROM too!
[Galaxy Ace II Android Development] Dr360r:
Latest build uploaded this late evening (11:28 PM): Google Maps is still closing without reason when looking for streets, be it in Device Only or High Accuracy or Low Power mode. Camera is still crashing if you film a video until you delete the video or move it out of its directory.
[Galaxy Ace II Android Development] 1nc0rr3ct:
I'm getting "mini" hangs with my CM 11. By mini, I mean it hangs for about 1-5 seconds and then gone. But after another few minutes it would hang again then gone. Its mostly noticeable when playing games.

I have Chronomochrome's CM 11 and Ace2Nutzer's Kernel 03/07
[Galaxy Ace II Android Development] shaqman89:
This would be better if you specify the CM11 version, since we have many of these around lately.

Anyway, since no one has reported a similar issue, it is likely that your root cause is one of your application, or the set of your configuration. In that regard, describing them would be better, but experimenting with your own needs first would be best.
[Galaxy Ace II Android Development] ace2nutzer:
2D Games ??

Post your LCD Type ... u can check this with the NovaThor Settings apk.
[Galaxy Ace II Android Development] 1nc0rr3ct:
In 2D games, only a little hangs (Bouncy Basketball, does it count as 2D?) Only for about like 1-3 seconds. In 3D games such as Clash Royale, Dungeon Quest, Lonewolf and SimCity, the hangs are very noticeable as it can take about 5 seconds or more. The reason I'm getting annoyed about this is because in Rox's CM 11, I have experienced no hangs with it (Specifically, in dungeon quest).
[Galaxy Ace II Android Development] ace2nutzer:
it's an known issue actually for WS2401 LCD Type ... it is maybe fixed soon .. (on final CM11)

For now u can try to enable zRam ... try Sizes from 75 up to 150 ... (which gives about 150 - 300MB zRam)
[Galaxy Ace II Android Development] 1nc0rr3ct:
Oh, okay. Thanks!

Oh, and... Is zRam an app? If so, could you link it to me?
[Galaxy Ace II Android Development] ace2nutzer:
Nope, u've to edit script in

/system/etc/init.d/01_zram

For This u need to enable Root Mode on CMFileManager ....

And before u've to Tap first like 7 times on Settings ---> about phone ---> Build number

then u can enable Root for apps on developer settings ... (new menu appears on settings)
[Galaxy Ace II Android Development] 1nc0rr3ct:
This is something new to me lol.

Any specific size of zRam you suggest so I won't bother going back and forth to change it again and again?
[Galaxy Ace II Android Development] shaqman89:
As mentioned above, size 75 to 150 should be okay.

So in the script you could try 75 at first, and if it's not, increase it gradually to 150.

Eg: 75, 85,..,150
[Galaxy Ace II Android Development] 1nc0rr3ct:
Alrighty.

Could you explain what zRam is and what it actually do?
[Galaxy Ace II Android Development] shaqman89:
This is something you could easily search.

https://en.wikipedia.org/wiki/Zram

In short, it helps in utilizing more RAM by compressing some part of it.
[Galaxy Ace II Android Development] 1nc0rr3ct:
Sorry. Its just I don't trust wikipedia that much. Anyways, thanks! The informations really helped a lot.
[Galaxy Ace II Android Development] shaqman89:
Lol. I agree with the sentiment.

But it was just to prove that it's easily searchable.

It just happens that Wikipedia was my first search result.
[Galaxy Ace II Android Development] IAmLucky:
can anyone tell me the difference between these LCD types? shouldnt LCD be the same on same model devices? As I have the same LCD type as guy above and I dont get any hangs. Maybe he needs to do factory reset or reflash
[Galaxy Ace II Android Development] shaqman89:
Both LCD types seems to be stable on different frequency. On the early days of kernel development, both LCD types (s6d and ws2401) gives different result when changing LCD modes and frequency.

So far, we have found the best known combination for both types and that's being used both in ace2nutzer and Chrono's kernel. But even so, according to previous discussions, ws LCD type is considered to be more prone to bugs or errors.

That being said, I also have ws2401 and have no issues related to LCD so far.
[Galaxy Ace II Android Development] Dr360r:
[MENTION=5840412]ace2nutzer[/MENTION] you mentioned LPM not working when you tried to implement Philz touch improved CWM. You mean that you shut the phone off, you plug the charger and the phone just turns on and loads system instead of going in LPM mode, right?
[Galaxy Ace II Android Development] IAmLucky:
thanks, seems like I don't have issues too. Only if I lower LCD HZ from 60hz to lower I get sometimes screen glitches after unlocking screen
[Galaxy Ace II Android Development] ace2nutzer:
Philz didn't try out... Only TWRP.. and it loaded recovery instead lpm :)
[Galaxy Ace II Android Development] Dr360r:
By the way i found that adding these 2 lines to the build.prop:

ro.ril.def.agps.mode=2 (or 1)

ro.ril.def.agps.feature=1

Makes AGPS data appear in the /root/data/gps folder. Not sure if it also means the phone actively downloads, store and use the lto (ephemeris i think) file you specified in the gps.conf but try it... 150714 actually stores the lto in the folder i mentioned, on latest build add this to make it happen.

EDIT: tried it. Much more satellites get locked faster.

Before that, i had the sensation AGPS was completely turned off and didn't use any data to speed up...
[Galaxy Ace II Android Development] ace2nutzer:
Thx ! - Will add this soon :)

First i want to make it bugfree ... then apply my optimizations .. and then new Software vsync for both LCD types :)

Then we've probably one of best ROM ever for ace2 world wide ;)

btw 12/03 is uploading ... if we've much luck ... everything will work properly :)
[Galaxy Ace II Android Development] Dr360r:
Anyway, out of curiosity: why did "Soft reboot" reappear as option with latest builds (the one after ChronoMonochrome instructed you how to solve the crashing apps issue)?

By the way have a look at build.prop, i think many other things can be optimized there...

With 160312 ROM, camera app no longer crashes after making videos.

Maps still closes without reason when looking for streets, even in device only mode.

No Java crashes.
[Galaxy Ace II Android Development] ace2nutzer:
because i switched to default repos from team canjica.

Well, actually i can say: Maps is still FC .. (probably an new issue with latest gapps or google play services itself)

and Camera is a bit buggy ... it sometimes FC when u switch from Foto to Video ....

I think those 2 Bugs will be hard to fix ... so they will stay for some time till we'll find proper patches for this .. Google just changes too often a lot of things ! - But at least Google Play Services FC + deep sleep issue + Stagefright leaks are solved ....

So now it's time to continue the work ... i can't stuck for ever on those 2 Bugs ;)
[Galaxy Ace II Android Development] Dr360r:
I had Maps closing without reason issue without Google Play Services installed (i haven't flashed PicoGapps yet) by the way.
[Galaxy Ace II Android Development] bebolint98:
Here Twich still didn't show live video and adobe photoshop still crash.
[Galaxy Ace II Android Development] ace2nutzer:
Nope, u can't use maps at all without Google Play Services ;)

Any other Version is almost always installed on /data ....

But at first when u have a fresh installed Phone ... then u've only Google Play Services installed on /system ..

and this of course only if u installed gapps ...

then later if there is an update of G.P.Services.. then it'll install and USE the newer Version in /data ...

Now it's clear enough ? ;)

Nope, here it works, ... tested twich, myvideo and Youtube in Stock Browser ... they all work now :)

As i said only Maps + Camera is Buggy ... strange thing anyway :)
[Galaxy Ace II Android Development] bebolint98:
Ok the twich , and youtube work here also. You don't know what will cause the photoshop crash?
[Galaxy Ace II Android Development] ace2nutzer:
Actually not really ... but i've 2 ideas to test :)
[Galaxy Ace II Android Development] Dr360r:
Uhhhhhh... okay ;) .
[Galaxy Ace II Android Development] 1nc0rr3ct:
Hmm... I wish this ROM will be done/bugfree before or on my birthay in May LOL.
[Galaxy Ace II Android Development] ace2nutzer:
how old are u then ?? ;)
[Galaxy Ace II Android Development] 1nc0rr3ct:
You know it haha ;)

My ace 2 has a natural cooling system... My palms have a sweaty glands hahaha! (Meh, not a good joke I guess since its true :P)
[Galaxy Ace II Android Development] inhirz:
How can I flash codina ROM on codinap ? I get an error "this package is for codina..."
[Galaxy Ace II Android Development] darktrixx:
does formatting system using twrp is safe? and what is it for also? thanks
[Galaxy Ace II Android Development] IAmLucky:
You can't ATM. Wait for ace2nutzer to make it for codinap also.

---------- Post added at 10:57 AM ---------- Previous post was at 10:54 AM ----------

well, I am not sure why it would be not safe... Format system means that it will wipe everything from /system. In this folder is installed ROM and system apps like camera, calendar and etc. Also Google maps. If you will format system and turn the phone ON it will be stuck in bootloop at Samsung logo. So after you format, install another rom.

---------- Post added at 11:00 AM ---------- Previous post was at 10:57 AM ----------

Never ever format modemfs
[Galaxy Ace II Android Development] bebolint98:
[MENTION=5840412]ace2nutzer[/MENTION] I also saw that when I try to connect my phone to pc with UMS it write systemui stopped. I put to MTP after back to UMS it works again.
[Galaxy Ace II Android Development] fluffi444:
But you formated DATA to fat32?
[Galaxy Ace II Android Development] ace2nutzer:
oops !! I don't see this !

Also he formatted UMS (sdcard0 to ext2.. even not optimal.. or? )

But why did u use an script ??

Just copy and paste will do the job.. now u do this all double and triple :D

Just follow Post #3 and format the new created Partitions over CWM correctly !

For F2FS: data, cache, system

sdcard0 = vfat

For EXT4: data cache system

sdcard0 = vfat

U need to format only the hidden partition to ext2 over ADB.. all the other things over CWM.
[Galaxy Ace II Android Development] LyrixTheDj:
After "re-partiton" by instructions, i format /system /data /cache to f2fs. Maybe coz it was a first run of "parted", before f2fs formating?

Now it look like:

PS Anybody knows how to HD make work in YouTube app? [MOD] YouTube 4.4.11 (v5b) by theos0o not working anymore to me in this "subj", maybe it needed Dalvik, not ART?
[Galaxy Ace II Android Development] fluffi444:
This looks good for F2FS...:good:
[Galaxy Ace II Android Development] ace2nutzer:
Yes now it's right.

I use OG YT .. and i can see Vidz in 720p on ART .. no Problem here.

[Galaxy Ace II Android Development] kjub6:
[MENTION=5840412]ace2nutzer[/MENTION] BATTERY !!!!! ... before I had the crstalXP !!!! and the CHARGING was 3x that fast :/
[Galaxy Ace II Android Development] LyrixTheDj:
Thanks you! It's work perfectly at 720p ;)

---------- Post added at 05:00 ---------- Previous post was at 04:55 ----------

It has choice! In "for developers" (or how it must be in english language interface) setting, almost at the bottom (end of list). Just go to setting and tap "search icon" then type "developer", next go to all search results and you find it. Default is Dalvik.
[Galaxy Ace II Android Development] faroukovic3:
Thnx . NOw U Answer Me correctly ;) Thnx . Now I'm waiting for the next build and hope it contains more governors !!
[Galaxy Ace II Android Development] Vexylle:
Is the GPS working on the latest rom? or is it bugged?
[Galaxy Ace II Android Development] kjub6:
guys look what I have found ;)

https://f-droid.org/repository/brow...edia&fdid=net.sourceforge.opencamera&fdpage=4

maybe nice to implement :) insteand stock

PLUS this is also awesome to implement ;) works like a charm

https://f-droid.org/repository/browse/?fdfilter=blocker&fdid=org.adaway

EDIT2 > and please help with the charging I use wall charging 2A samsung device ... usb interface ... and before CrystalXP it was 3x so fast !! :/

EDIT3 > where can I find NT-APP and abb-charger ? is in dev.tools ?

EDIT4 > I have switched storages (NovaThor) with new ROM ver. how can I prevent complete reinstall (I always went through full reinstall)

EDIT5 > when I install, I install directly also gapps ... when I boot my 2step verification always fails because the sms is not working in this stage ... I need to login to google later ... the result is that in the notification area / settings I dont see int the owner my picture :/ and dont know how to recover it ... I press owner and it wants me to connect it with contact :/ not connects me with accounts details

EDIT6> any chance of updating TC11 ? CrystalXP has cool lockscreen notifications as L5.0 looks realy cool :/ miss it folks or can you reccomend any substitution ?
[Galaxy Ace II Android Development] ace2nutzer:
NT-APP = NovaThor Settings

abb-charger = Charging control / Current control in NT-APP :)

To change the Current correctly, u need to follow the instructions on post #3 ....

Yeah after 1 Year of Development this Rom is still buggy..... GPS, Wifi and Bluetooth are not working !!!! :highfive:
[Galaxy Ace II Android Development] soko3:
[MENTION=5840412]ace2nutzer[/MENTION]

dude, you seriosly f***ed up something with charging

after 20 minutes of charging battery is still on 15%and phone is hot

on stock (rox) kernel, everything is normal...

kernel is good, smooth, etc, but why should i install it if i cannot charge phone unless it's turned off
[Galaxy Ace II Android Development] ace2nutzer:
U read Post #3 ? ;)

In offline Charging max. current is 500mA

Fast charging only when the Phone is ON.. and changed Current over NT-APP...

To check actually charging current use this Widget:

https://play.google.com/store/apps/details?id=com.manor.currentwidget&hl=de

Tipp: the showed Value on charging is the current what go IN the Battery.. that means.. whe you are in offline mode (wifi off, Brightness 1%) then the Value what u see on screen on is ca. less 100mA .. because 100mA go to the Hardware.. but when Screen is OFF.. the Phone needs only ~ 30mA .. therefore it makes no sense to charging the Battery on LPM (non booted system)

Tipps 2: Check on ~ 10 - 30 % the charging current with this trick.. screen is off.. wait 3 minutes.. unlock the screen very fast... no u see on the widget the charging current for screen off !

------->

For me, @ 900mA in NT-APP and with the

Stock Charger max. output 700mA

shows me: 670mA

The missed 30mA = 700mA --->

max. output

is the current what the Phone needs on screen OFF... !

Therefore everything correct !!

I'm hope that i don't need to write such things one more time.. it's very annoying guys :o
[Galaxy Ace II Android Development] MarquesYOLO:
After first cycle charge battery with your last F2FS build, I think I recover best, or almost best, battery life I remember, but smoothest. I hope this will be for a long time.

I have only one question, know you what is the first value in kernel wakelocks?

Thanks for your work [MENTION=5840412]ace2nutzer[/MENTION]
[Galaxy Ace II Android Development] ace2nutzer:
That's great... the first value in kernel wakelocks is just the system wakelock.. that means @ screen off.. when the system has something to do.. like Syncs .. check e.mails whatzapp etc.. it's called wakelock.. because the Phone is awake and not in deep sleep.. it can not work (check e.mails) in deep sleep.

But the only thing: Why are u using min. freq 400Mhz ?! I Suggest with the actually Kernel min. 200Mhz for best Powersave !

I'll try to adpt. some Gov. to use even 100Mhz or even also 50Mhz as minimum.. without using more battery.
[Galaxy Ace II Android Development] MarquesYOLO:
I had not realized of minimum frequency until I saw it in BBS hahaha. Don't worry, I've already changed.
[Galaxy Ace II Android Development] ace2nutzer:
Yes, because from 300Mhz and up, APE and DDR OPP runs @ max. speed 100%.. and by 200Mhz it is only 25% :o

So no wonder that your Statistic is not optimal ;)
[Galaxy Ace II Android Development] doctormord:
Somebody could tell me how to change to ART the proper way? Every time I'm trying, phone app is force closing at boot.

I did changing to ART in developer settings, then let the phone reboot. Takes some 10 minutes to finish but then phone apk is force closing.
[Galaxy Ace II Android Development] LyrixTheDj:
I don't know, may be in CWM make a backup, try wipe Dalvik cache, after that switching to ART. I did a clean install subj ROM, without restoring a system/data, all was successful. After that installed gapps-modular-pico and all of needed apps from play market, except YouTube.
[Galaxy Ace II Android Development] ace2nutzer:
[MENTION=1130928]doctormord[/MENTION]

try this:

- wipe cache

- wipe dalvik cache

- cwm backup

- boot and switch to ART..

- be patient.. it can take up to 30 Minutes (for me ~ 25 minutes) (depends on the amount of apps)

I u again have problems with FC.. then open the terminal emu. and type "df" and post screenshot here...

May be not enough space free.. :cowboy:
[Galaxy Ace II Android Development] Dr360r:
It doesn't bootloop. There's nothing to boot.

Kneel before [MENTION=5840412]ace2nutzer[/MENTION]. He finally fixed Google Maps on build 160313, once and for all! :highfive: :good:
[Galaxy Ace II Android Development] ace2nutzer:
Can someone pls test if maps works on 13/03 ? thx.

EDIT:

AMAZING !

IT: BESTIALE !

DE: AFFENGEIL !
[Galaxy Ace II Android Development] ace2nutzer:
Can u pls test if photoshop works on 13/03 ?
[Galaxy Ace II Android Development] bebolint98:
Yes, I download it and I write that works or not. Can you please look into what cause the problem which I write in post #3780.
[Galaxy Ace II Android Development] Dr360r:
In questo caso, MERAVIGLIOSO ;)
[Galaxy Ace II Android Development] 1nc0rr3ct:
Ace2Nutzer, please tell me I'm getting closer to my wish :P
[Galaxy Ace II Android Development] darktrixx:
thanks sir. but it will be ok if i format system then flash any rom and gaps like ace2nutzer cm11? currently im running chrono's cm11.

EDIT: for example im in cm11 by chrono with twrp recovery, does formatting system will remove the custom twrp recovery also?
[Galaxy Ace II Android Development] bebolint98:
Fantastic, now works, didn't crash. Maps also works now and camera didn't crash while change between photo and video. Thanks!
[Galaxy Ace II Android Development] Dr360r:
[MENTION=5048051]darktrixx[/MENTION]

I don't really know, i prefer not to risk causing you trouble.
[Galaxy Ace II Android Development] Sylvinette:
So, it is worth to using new CM11 a2n right now?
[Galaxy Ace II Android Development] Dr360r:
@up

Definitely, in my honest opinion.
[Galaxy Ace II Android Development] Sylvinette:
Can you test with uploading a video to Instagram?

In older CM11, it didn't work.
[Galaxy Ace II Android Development] Dr360r:
I'm very sorry, but i don't have an Instagram account and i don't feel like having one.
[Galaxy Ace II Android Development] darktrixx:
thanks.. :) i think your right, it would better for me to not format system. :)

but with stock jelly firmware with custom kernel by chrono i can install ace2nutzer cm11 but failed to install gapps, it says not supported. i found the gapps in ace2nutzer server
[Galaxy Ace II Android Development] Dr360r:
However, i find the Nandroid backup method to be incredibly reliable.
[Galaxy Ace II Android Development] Sylvinette:
Alright I'll test it by myself later.
[Galaxy Ace II Android Development] Dr360r:
By the way i looked into the build.prop of build 150714 and ro.ril.def.agps.mode and feature lines are missing. But lto.dat files get downloaded into /root/data/gps anyway...
[Galaxy Ace II Android Development] darktrixx:
sir [MENTION=6902149]Dr360r[/MENTION] how is a proper way to install this rom from stock jb firmware? im trouble flashing this cm11. i dont have encounter any problem when installing cm11 by chrono. :) guide me please. thanks. im now on stock jelly bean with crono kernel.
[Galaxy Ace II Android Development] Sylvinette:
Just want to report, uploading video to Instagram still didn't work. It stopped working after trying to reupload.
[Galaxy Ace II Android Development] Dr360r:
[MENTION=5048051]darktrixx[/MENTION]

Sorry, but, sincerely, i don't want to risk giving you wrong instructions and damaging your phone. I can only tell you the first step, then you go on your own. Go into Settings->About phone (the last icon on the settings page) and check Baseband version. You need to make sure it's a Jelly Bean baseband (mine is I8160XXNA1) otherwise if you go flashing the ROM it'll become XXXX and you won't be able to phone, send messages, receive them or connect. If it's not Jelly Bean baseband then you'll need to properly install a JB ROM. Until then, don't install custom ROMs.
[Galaxy Ace II Android Development] darktrixx:
dont worry sir. i know how to use odin and i have a backup of nv data using szaby59 tutorial. :) and i have a jb firmware collection in my laptop. the only problem is failed to installed gapps in ace2nutzer cm11. lately im successfully tried on cm10.2/chronos cm11/ cm12.1 and cm13 without installation problem. only this cm11 by ace2nutzer i encounter problem. i want to know how do you install this over your ace2 sir. thanks :)
[Galaxy Ace II Android Development] Sylvinette:
@up

I just came to this ROM from CM13 30 minutes ago.

Wipe data + cache

Wipe dalvik

Format /system

Mount system + cache

Flash ROM

Flash Kernel

Flash NT-APP

Reboot to system

Yes for root

After first boot, going to recovery again

Flash GAPPS

Reboot to system

It works for me, but since you are from stock ROM, format system is not necessary I think.
[Galaxy Ace II Android Development] darktrixx:
thanks. very well detailed. i wanna confirm something sir. for example im on cm12.1 now. and i format system. does custom kernel by chrono still remain? thanks
[Galaxy Ace II Android Development] Sylvinette:
I'm not sure, but I think it doesn't remain, recovery format the whole system.

Like when I try to change from ChronoKernel to ace2nutzer kernel, usually I format system first and then replace with a new one (ROM and kernel).
