Ok ... Flash latest kernel, it has lower lcd freq... It should help. Please report if it'll fix the Problem.
[Galaxy Ace II Android Development] ace2nutzer:
Not needed.
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] it seems like it solved problem. I will report later if it were any problems. Thank you.
[Galaxy Ace II Android Development] ace2nutzer:
Strange. Usually it should stay on idle on 3g in order to save battery ... And when traffic is somewhat higher, it'll switch to hspa.

I've tried Revision 6 and later 7 .. (With reboot of course) and it changed nothing ...

So are u sure that it really makes any difference for u ?
[Galaxy Ace II Android Development] darktrixx:
sorry sir [MENTION=5840412]ace2nutzer[/MENTION] . my bad. :) i though i solved the problem using that code, i figured out that the simcard provider issue, i change my simcard provider and solved the problem. sorry brother, peace :D
[Galaxy Ace II Android Development] Hummer951:
does viper4android is compatible with device? and also possible to include in the build? sorry no idea.

Viper4android works perfectly on my Ace 2 with this ROM. No need to include, just download from XDA and install.
[Galaxy Ace II Android Development] darktrixx:
[MENTION=4374192]Hummer951[/MENTION] thanks for the info mate, will try that later,

edit: already installed viper4android thanks working perfectly
[Galaxy Ace II Android Development] Culateralligator:
Sorry for lasting on answering... Screencast micro doesn't work on latest CK and CM11.
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] the "double screen problem" just came back, I report. Too bad... Oh, right now it went away and it is ok, LOL.
[Galaxy Ace II Android Development] ace2nutzer:
With 07.06.16 kernel ? If so, i'll see what i can do for your lcd.
[Galaxy Ace II Android Development] lace_hvc:
I flashed the 07.06.2016 kernel too. Had a problem with screen brightness once. changing the slider to maximum lead to darker screen. setting the slider to mininum still showed a bright screen. But a reboot fixed it.

I got another problem with gmail though. No contact suggestions when I try to send an email and my 2nd account in the gmail app (gmx email account) always disappears after reboot.

I saw a few receivers were turned off (EmailBroadcastReceiver, MailIntentReceiver, EmailUpgradeBroadcastReceiver). no idea why. turned them back on, but EmailUpgradeBroadcastReceiver receiver stays off after reboot..

And the attachmentservice of gmail is always disabled, even after trying to enable it.
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] yes, I had this problem. For now it is ok. I dont know about what it depends. Yesterday was ok, when I wake up, screen was "doubled" for 10 minutes and then has turned to be ok. I dont know, if problem will still exist I will report that.

Edit. One more thing. Could you tell me how big is difference between battery lifetime at balansed and performance mode?

Edit 2. I see that after click on random app the time between click and respond is much less, I love that. So here is my question. Is it possible to reduce "dead time" between click and respond in Main buttons? I mean 3 buttons: "back" "home" and that third which I dont know his name. And then reduce this time in "hold home to see list of processes"? I would really appreciate that.

Edit 3. What sould I do to make "google voice search" work since when I click "voice search" it says that it isnt installed
[Galaxy Ace II Android Development] Sylvinette:
Just install all latest build, I did clean install. So far is good, but sometimes I got that double screen problem. Got it when my phone locked, 3 minutes or later went to normal, and it can be back again soon with double screen like glitch. Mine is s6d* screen type.

I cannot screenshot, it says my storage may be in use.
[Galaxy Ace II Android Development] ace2nutzer:
no need to reboot phone, just turn the screen OFF .. and the problem is fixed... this only happens sometimes after an reboot.

Ok i'll rework the LCD (MCDE) driver ... i hope it'll work smooth and without such lcd issues.

It's not proportional ... so it's much higher consumption the higher the CPU freq is. Can't say in % .. no time right now... but u can search this thread for power consumption on CPU freqs .. u'll find some stats with mA Values for every CPU freq.

Anyway , the best CPU freq is just 800Mhz ... then more power and battery drain is on 1000Mhz .... but still acceptable ... and 1100 - 1200Mhz is very high power consumption. Maybe i'll change "performance" profile from 1100 to 1000Mhz .. i think it's better.

Also i can try to reduce GPU Voltages ... and use for performance profile just 500Mhz instead 650Mhz .. that should work as well, but it'll drain much lesser battery. So something like ECO performance profile .. why not ? :D

Yes it's possible, by a change i can reduce it.

See ROM Changelog for freezed Apps .. then open FileManager .. and just search it on /system/app and /system/priv-app .. and rename the freezed app *.bak in *.apk .. that's it !
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] If you are able to reduce that time on buttons... I think it will affect a lot on smooth&responsible. Just like with response while clicking on app. Would be lovely to have it.

I noticed that for daily usage 800mhz is ok except some complicated swiping between opened apps. Playing 2d games on 1100 mhz is really comfortable. As you wrote, 1000mhz seems to be enough. Compromise between battery drain&performance. Please think about it too.

About gpu. I have switched manually mhz to 700, really dont know if it isnt too many and dont know if it is switchining automatically in balansed & performance. But if you could try to do something with gpu voltages just for better lifetime - would be cool.

Do number of installed&frezzed apps affect on performance?
[Galaxy Ace II Android Development] ace2nutzer:
Nope, it has nothing to do with the smoothness + performance .. also not responsiveness ... it'll only decrease the delay till the recently apps menu will appear ... nothing more :)

Compiling new Kernel with hopefully fixed S6D issue and changed perf. profile:

CPU 1100 @ 1000 and GPU 650 @ 500Mhz. Also Adapted GPU Voltage (lower) for 450 and 500Mhz Step.

Check post #3 for CM Perf. Prof. config.

Yes of course ! The less apps, the better ...

btw: freezed apps is same like removed apps, but with the only difference that a freezed app will still take space on the NAND-flash.

(nut it'll not consume cpu time or RAM at all)
[Galaxy Ace II Android Development] greeceeeee:
Maybe you laugh at me :P but luckily I found that when you double tap on status bar the screen goes off...
[Galaxy Ace II Android Development] ace2nutzer:
That's normal .. and nothing new ... u never checked all possible Settings u can do on CM ??? (General Settings App)

Also u can adjust Brightness if u hold and then swipe over the status bar
[Galaxy Ace II Android Development] ace2nutzer:
New Kernel + NT-APP is Up !!

Changelog:

20160609:

Reworked S6D LCD Driver *

CM Perf. Prof.: - changed "performance" profile: CPU: 1100 @ 1000Mhz & GPU: 650 @ 500Mhz

Adjusted GPU Voltages - lowered for 450 + 500Mhz

More Battery-friendly "performance" profile :)

NovaThor Settings v1.7.4

Sync with Kernel GPU Voltages

Custom GPU UV is now 550-700Mhz instead of 450-700Mhz

* = attempt to fix LCD issues on some S6D LCD's.

NOTE: it's highly recommended to updated to those 2 builds.... don't update only NT-APP or kernel, as it'll result on wrong GPU Voltages algorithm !
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] I will try in few hours.

Yes, technically, reducing time doesnt affect on smooth&perf. but who wants to wait 2 times longer for response? Its just same situation as reduce time from click on app to response. In my opinion - shorter - better.
[Galaxy Ace II Android Development] Sylvinette:
Works perfectly!

I do reparted memory to 3GB data, and my sdcard only 1mb. Do I still need swap storage?
[Galaxy Ace II Android Development] IAmLucky:
You need. Otherwise, your camera should crash (as it happens to me) also your phone might get unstable as data gets saved in your 1mb storage, so its a better choice to swap storages.
[Galaxy Ace II Android Development] TzuYu014:
how to use reparted v1.0 ?
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=7270573]TzuYu014[/MENTION] Its soluted in first page, post #3 if I am not wrong. Anyway, follow first 3 posts.
[Galaxy Ace II Android Development] raz82:
I understand correctly:

install cm-11-20160604-UNOFFICIAL-FULL-codina.zip, update new kernel, update NovaThor Settings.

correctly?
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=7506669]raz82[/MENTION] yes.

[MENTION=5840412]ace2nutzer[/MENTION] do you know something about google play error -18 cannot install app?
[Galaxy Ace II Android Development] ace2nutzer:
try to switch sdcard0 with 1 or 1 with 0 ... after installation u can switch back to old config.

Some rare apps don't quite understand that real sdcard0 is now sdcard1 .. so they just try to install on real sdcard0 (even if swapped)... and if reparted it's only 1MB .. and installation fails.
[Galaxy Ace II Android Development] arroyo:
1MB on internal SD is way too low value. Even with SD swap. Many applications (including XDA forum app) won't install if they won't see 10MB or more free space on EXT-SD (before SD swap it was internal one). I have no app installed on internal SD and it actually have 40Mb free from 100MB in total.
[Galaxy Ace II Android Development] ace2nutzer:
yeah maybe u're right, but as i said, if an app wants to install something on the small sdcard, just swap sdcards, reboot, install the app, switch sdcards again and reboot. It's maybe a bit annoying job .. but that way worked always for me. So u'll not waste any space. Also i don't know which size is optimal ... too low is bad, and too big is wasted space .. also u can't it use for other things like camera or music .. since there should always some free MB for installing apps ... and even the 100MB .. earlier or later it'll be full too .. and then ? same problem again ... resize partitions again, or simply use my mentioned method with swap storages :)

For me, i've around 130 Apps installed, incl. system apps, and on sdcard0 only approx 130KB are used from 980KB :)

(honestly i format it sometimes over cwm (!!!) .. when i see that the used space is too high ... and so far i can't face any side-effects ... )
[Galaxy Ace II Android Development] lace_hvc:
Fixed my gmail problems. do not disable feedbackservice of google play services!! :P

Is the app or ROM responsible for the cut-off 'Advanced' tab?
[Galaxy Ace II Android Development] Kilem:
Hello [MENTION=5840412]ace2nutzer[/MENTION] and others :),

I have a problem with the YouTube-videoquality on my ace 2.

It is just possible for me to select between 144p and 240p. :( :confused:

My Phone is running your current Rom 20160604 and kernel 20160609 with NT-settings v 1.7.4.

Anyone else with the same problem?

I have made a clean installation and everything is working fine.

Its a great rom BTW! Really good work!:good::D

But "Spirit free" isn't working, even if with the method to swap to "Galaxy S3/Note/S2_ICS" and i would like to deinstall the "Og YouTube", "OG Youtube downloader" "and BetterBatteryStats" app,

but i dont know how to do it, because there is no option for deinstalling them.:confused:

I look forward to hearing from you soon.:)

Yours sincerely kilem.
[Galaxy Ace II Android Development] [-GuTi-]:
So use Og YouTube, you can choose HD in this app

Spirit free is working for me
[Galaxy Ace II Android Development] lace_hvc:
My settings (although im on spirit UL):

Method:

Set to S3/Note/S2_ICS

Band:

Set to 100KHz

Channels:

Set to Stereo
[Galaxy Ace II Android Development] ace2nutzer:
i never had such issue. did u change lcd_density in build.prop ?! What is that for an app ? You maybe downloaded app for other devices ... our devices are HDPI.

btw: just forgot to mention: DO NOT UPDATE the OG_YOUTUBE App when u open it .. !! ALWAYS SAY "LATER" .. otherwise u'll end up with low Video Quality !!

So try to delete all Youtube Apps, and simply install latest build again .. then u've like me: 144, 240, 360 and 720p ;)

(of course on videos that it's available ... if the video has only 240p .. then u can't use 720p ).

as for Spirit FM .. it works fine .. try to toggle loudspeaker with headphones .. till it'll work ... also u need to insert headphones .. because it's used as FM Antenna !

U can simply delete system apps over FileManager ... for this u need to select ROOT MODE on CMFileManager .. then u've access to /system/app and /system/priv-app .. but if u're new on android, it's highly recommended to NOT delete system apps.
[Galaxy Ace II Android Development] lace_hvc:
I didnt change anything. its the settings of betterbatterystats app. Doesnt bother me much. just reporting.
[Galaxy Ace II Android Development] ace2nutzer:
Ah okay .. thanks for noticing .. strange thing .. because i'm pretty sure that i've downloaded right package for HDPI devices .. so i guess it's app issue itself.

Just ignore it.
[Galaxy Ace II Android Development] lace_hvc:
Installed the xda version again. Still the same. Ignoring from now.

Btw when the phone is shutting down or booting (i think also in recovery), and I plug in the charger, it wont charge. It will show the charging icon, but the percentage of the battery stays the same. It has to be off or running the ROM for it to charge the battery.
[Galaxy Ace II Android Development] dr@xxon:
Problem

Hi

I have problem When I turn on screen I see only gray vertical stripes. I must several times turn on screen too stripes disappeared.

My LCD type: WS2401

I have this problem with kernels: 20160606, 20160607 and 20160609.
[Galaxy Ace II Android Development] ace2nutzer:
Power source ?
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for report, i'll rework ws24 driver.
[Galaxy Ace II Android Development] TzuYu014:
i used reparted and works perfectly but i couldnt move the app in sdcard and also on Play Store.
[Galaxy Ace II Android Development] casanova12:
automatic brightness works for you?
[Galaxy Ace II Android Development] ace2nutzer:
How it should work without light sensor ??
[Galaxy Ace II Android Development] casanova12:
when I uninstalls the launcher and replace with nova full version. keyboard numbering dispare.
[Galaxy Ace II Android Development] lace_hvc:
Original charger. power plug. not usb cable. Is that what you mean by power source? ^^

I got LCD WS2401 too. only previously decscribe problem with brightness sometimes. and as u said screen on/off fixes that problem.
[Galaxy Ace II Android Development] ace2nutzer:
Ok i'll check soon (i don't have here an org charger) but with usb attached to the Computer, i can charge always .. Even on cwm. Can u try too ?
[Galaxy Ace II Android Development] gepel:
No problems at all on mine. (ws2401).

p.s. i have uninstalled the nt settings.
[Galaxy Ace II Android Development] shaqman89:
Just wanna say that I also have no issues with screen/lcd. I'm on ws2401
[Galaxy Ace II Android Development] _mD:
Not trying to disrespect your ROM or anything. I've been lurking around here for a long time so I'm not that new...

Anyways, is the Nova Launcher really necessary? Can't it be just Trebuchet? Some people like launchers, some don't. In fact I hate styling my phone to look elegant. I prefer it to be odd-looking but fast and powerful. It adds a little touch. IF ITS NECESSARY for smoothness, then okay. Not going to argue.

And another thing, OG YouTube. Again, is it necessary? I mean, some people don't pay attention if they could download videos or anything or maybe someday they would. If they want to then they should go do it themselves. I still prefer the original YouTube even though it doesn't have HD videos (not that useful to me anyway, I won't let my phone suffer from 1080 videos). Oh and, the OG YouTube included isn't even updated. I can't download anything. Maybe at least include the latest one from OGMods? If there's a reason behind using the old YouTube, tell me.

So, yeah. That's my feedback. Take it in a positive way and all will be fine. If you're going to argue to just change ROM, my answer would be 'we both know this ROM and ace2nutzer is the only hope currently to keep Galaxy Ace 2 usable in modern days'. That's all. Thanks.
[Galaxy Ace II Android Development] shaqman89:
Actually this has been discussed before. And in the end, it comes down to what the majority wants. Besides, if you happen to be the minority and don't want it, deleting it isn't hard at all.

Anyway, most of us agree that Nova Launcher is smoother than trebuchet, so that was the reason for the inclusion.

Likewise, most of us agree that a specific version of OGYoutube is better than other youtube players for our phone, so it was included as well.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah i know.. It's like s6d .. Most works, and some rare cases have issues.

Btw on next rom build there is maybe a way to make cm perf. Prof. Permanent .. That means the selected profile will stay even after an reboot, and if u choose performance, then it'll boot even faster because it'll use that profile very early .. Instead after typing a pin.

So far on latest build it's only half working...

u can use build.prop line: sys.perf.profile=2

then it'll boot faster as it'll use performance profile (1GHz) for around 25 seconds... and then it'll reset back to "balanced"

Don't forget it'll use more battery.

Edit: the included og yt version is the only one properly working version. Really can't understand why so many users don't like it...

Here just some advantages:

No ads, videos play immediately without to wait 20 or 30 seconds for the spot.

Full hd, not pixelated.

Ability to download the audio as mp3 with just one tap.

Ability to hear the sound of the video clip with screen OFF = saves battery.

Less power consumption compared to latest yt Version or using yt over the browser.

Even good quality on 240p

And maybe more... but u guys don't like it :D
[Galaxy Ace II Android Development] lace_hvc:
USB charging during recovery, booting, shutting down and power off worked.

I only noticed it a few times with the charger. Maybe its only my issue. Will try another charger in the coming days.

Regarding the posts about the ROM and the added pre-installed apps:

I did a dirty installation, but then had duplicates of the apps u added cause I was already using them (ogyoutube, betterbatterystats, spirit).

Can I simply remove those apk in the ROM.zip before installing it? Or renaming them to .bak?

And for the ones you froze, the settings are gone, when I install the ROM and change .bak back to .apk (lockclock for example). Can I change the lockclock.bak to .apk inside the ROM.zip before installing?

That would be great.
[Galaxy Ace II Android Development] ace2nutzer:
With the original charger it should work fine ... the issue you mentioned i've faced it so far with an third-party USB Charger ... this is normal.

It's better to remove them from /data/app .. then next time u will install ROM update, then u don't have same problem again.

Also u'll make some free space on /data ;)

Oh i'm sorry :) It makes no difference, if u'll rename before or after the ROM installation :) But for the next time it's better to rename before u'll install the ROM .. then u'll prevent to loose Settings for such apps again :)

EDIT:

btw added on Post #3 a little Trick how-to unlock some more free space on /data and /system:
[Galaxy Ace II Android Development] shaqman89:
Some of us like it, myself included :D

Thanks :good:

Wouldn't this trick make the file system fragmented faster? I got this impression from reading the man for tune2fs. But besides that, I checked my file system using tune2fs - l and it seems that reserved space is already 0. Could it be default or am I reading the info wrong?
[Galaxy Ace II Android Development] ace2nutzer:
on system or data ... (probably system) it's already 0.

But for just in case i added both partitions .. it can't hurt :)

And nope, it's not by default to 0 .. check the diff with "df" before and after ... but if u did it already .. then u can't see the difference now.

But for me, i checked it with df .. and there was a difference after executing that command.

Also it's not a problem for fragmentation ... it's not a HDD :) .. it doesn't matter on flash storages ;)
[Galaxy Ace II Android Development] BlkPant3R:
Sweet
[Galaxy Ace II Android Development] ace2nutzer:
@up

thanks !

Just OT

Are u a real Black-Panther-Party Member ? ;)
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] what are you planning to improve in future? Is it possible to increase something what affect on performance?

Is possible improve quality of camera?

The "double screen" problem is gone.
[Galaxy Ace II Android Development] ace2nutzer:
That's great @ double screen ! [MENTION=6575591]Sylvinette[/MENTION] for u too ?

As for camera: i think it's already optimized by cm Team .. So i don't want to mess it up, since it can cause FC i.e.

As for improvements: if i've some good new ideas what i can easy manage then yes, i'll do.

But for now i think it's maximum optimized.

Of course it's still possible to increase performance by binary code optimizations but it'll decrease code quality and stability... That's why i'll not do that.

Anyway u can expect better code quality on next build.

And for now i'm debugging/optimizing Settings.apk app.
[Galaxy Ace II Android Development] lotrzyk0:
[MENTION=5840412]ace2nutzer[/MENTION] what about decrease delay after click on one of three device buttons which I mentioned in the past? I will be much greatful because waiting for response is kind annoying especially when hold "home" button.
[Galaxy Ace II Android Development] Sylvinette:
Yes double screen issue is gone.

Btw, my sim card has been locked since there's an app like "Stk.apk (Sim tool Kit)" in old build ROM, so whenever I boot up my phone, at the first time it makes me to input the 4 digit PIN.

And in the latest ROM, you said: Stk.apk (Sim tool Kit) is in freezed apps. How do I unlock my sim card?
[Galaxy Ace II Android Development] ace2nutzer:
They have 2 functions. Short press and long press. I really can't decrease home button delay. It's already too short.. If u open an new app and then close it and u very fast press home button then the last app will not appear ... Then press back button . then try again .. And it'll show up. That means it's already too fast.
[Galaxy Ace II Android Development] ace2nutzer:
Sounds strange, i never had faced any differences on pin side ... No matter if with sim toolkit or not.

Anyway u can reactivate that app by simply renaming from stk.bak to stk.apk Then reboot.
[Galaxy Ace II Android Development] lace_hvc:
Can confirm. My phone always asks for the SIM PIN after boot - with stk.apk installed or frozen.

Check ur settings/security/set up sim card lock
[Galaxy Ace II Android Development] lotrzyk0:
Ok I understand.

Is it possible to force 720p for youtube?
[Galaxy Ace II Android Development] ace2nutzer:
@up

I'm not the Dev. of OGYT ..... also i don't know if i'm allowed to manipulate his App !

And, if we can do that, then we need to decompile the app ... or we need the source Code...

Roughly i found this:

https://github.com/OGMods/OGYouTube

But looks somehow old .... i will check it deeper with time.

But honestly, 720p is too high, it'll drain a bit more battery .. and it takes longer for starting the video. I would set by default 360p instead the 240p. .. it's already fine.
