[Galaxy Ace II Android Development] ace2nutzer:
vape is the power supply for some devices like as far as i know: GPU, Sound-Chip, LCD, and probably also for the 3G connection...

Such devices are always for every phone different and unique in Quality .. that's why for some it can work with low voltages .. and for some not ... it needs more voltage to run stable. ;)

Actually i had undervolted from 1,15V @ 1,025V

Next build i'll try @ 1,05V
[Galaxy Ace II Android Development] greeceeeee:
For me the luminosity works fine,check again if it is enabled on settings
[Galaxy Ace II Android Development] lab34:
OK ! I have it :good: Just with the time displayed, it works well ! Thank you !
[Galaxy Ace II Android Development] Vexylle:
Thx [MENTION=5840412]ace2nutzer[/MENTION] i'll test it with NT app 1.6.2
[Galaxy Ace II Android Development] ace2nutzer:
[MENTION=5535372]Matteo90[/MENTION]

Oops sorry guys .. i was wrong ... it can't work with NT-APP 1.6.2 ...because it doesn't set higher gpu voltages.

Pls try u guys this simple workaround:

Install again in a row latest kernel + latest NT-APP and then before turning ON 3G Connection just disable (check) Mali AutoBoost GPU in NT-APP and use static GPU freq 400Mhz ... (pls tap on "400Mhz" even if it's already selected) .. and then turn ON 3G Connection and tell me if it's stable or not ... (because static 400Mhz uses higher gpu voltage)
[Galaxy Ace II Android Development] Vexylle:
Stable so far. I'll keep an eye on it for the evening.
[Galaxy Ace II Android Development] ace2nutzer:
Okay thx, that's great !
[Galaxy Ace II Android Development] Matteo90:
Works for me too, hopefully it'll stay that way. :fingers-crossed:
[Galaxy Ace II Android Development] ace2nutzer:
Still stable ??? - If yes, can u pls test this new Kernel ? - it has same voltage like the build u're actually using, but undervolted by -25mV

So i need to know if this new build is also stable @ 3G or not ... of course after installing this new build, first disable 3G .. then go to NT-APP and activate again Mali AutoBoost (uncheck) and then try to connect for 3G.

Install also in a row this test-NT-APP:

NovaThorSettings164_test.zip - 497.05 KB

and kernel:

ace2nutzer.kernel.4.4.x_20151020_codina.p.l.zip - 9.86 MB

after your testing ...then i know what's the right voltage for the next build.

btw: WS2401 LCD Freq is @ 50Mhz ... but video.modes not fine-tuned (will do this week) ... so if somebody want to test ;)
[Galaxy Ace II Android Development] Vexylle:
installed, and testing, turned 3g on and have no restart till now
[Galaxy Ace II Android Development] ace2nutzer:
Okay, that's good... have u do all the things i wrote ? also installed test NT-APP and enabled Mali AutoBoost again ??

It's also good to test if with disabled MaliAutoBoost it's also stable ....
[Galaxy Ace II Android Development] Vexylle:
jep everything
[Galaxy Ace II Android Development] ace2nutzer:
okay that's enough for testing this build... hmm try pls again latest build + latest NT-APP accorind to the changelog ..

so not the test kernel + test NT-APP .. and test once again one time with enabled Mali AutoBoost and one time with disabled Mali AutoBoost.

Before u make first test .. just change the Mali AutoBoost setting .. so if it's enabled, then disable, and if disabled, then enable it ... and test 3G .. then test also disabled/enabled ...30 minutes is enough .. not needed to wait longer .. because i'll add +25mV on stable voltage to make it fail-safe ... so later it's 100% stable :)

Thank u for your time.
[Galaxy Ace II Android Development] Matteo90:
Wasn't stable for me: after 10 minutes of listening to music with 3g on, it started the rebooting routine until I switched back to 2g. Also battery charge indicator is buggy, it dropped from 50% to 33% in a couple of minutes, and after a restart jumped back to 48%...

I'll try this test kernel, hopefully I'll be more lucky with it.
[Galaxy Ace II Android Development] ace2nutzer:
Thx for testing ! - Nope .. then u don't need to test this test kernel .. because it has lower voltage than the test build before...

(i mean the trick with simply disabling Mali AutoBoost ! )

I'll make new build with more voltage.
[Galaxy Ace II Android Development] Matteo90:
Funny, beacause this test version seems to be working fine, I've been playing music for more than 30 minutes with 3g data on, and nothing happened.

Or perhaps this reboot thing only kicks in when the phone switches to a different cell tower, as I was both times on the bus/tram when the reboots started... :confused:
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!

Changelog:

20151020:

MCDE: [WS2401] Adjusted LCD Freq at 50Mhz

Mali: AutoBoost: Revert use lower vape voltages if disabled

better battery lifetime

Use it only with NovaThor Settings v1.6.5

(Download on FTP Server)

NovaThor Settings v1.6.5

MaliAutoBoost Adjusted vape Voltages like in kernel

Clean Build

Use it only with ace2nutzer kernel version "20151020" or later !!!

(Download on Dev-Host)

Note:

After installation go to NT-APP and disable/enable Mali AutoBoost, at the end set it like u need .. on or off ...

Nope, it has something to do with vape voltage for 300 - 400Mhz ...

It was a bit confusion .. as i changed the voltage in kernel and in NT-APP ..

also there is different Voltage with ENABLED MaliAutoBoost and with DISABLED Mali AutoBoost .. that's why we've different results..

But well, just let's forget this .. it's too tricky to find stable Voltage for everybody .. so i just revert the Voltage to stock 0x24 (1,15V) and everything should work fine now... - Anyway thanks who tried to help :)
[Galaxy Ace II Android Development] manthes:
Any reason to use this new kernel with s6d because previous working fine ?
[Galaxy Ace II Android Development] ace2nutzer:
basically no big changes for s6d .. but anyway a bigger vape voltage increases the stability when using things like 3G / audio at the same time.

And especially when using Mali AutoBoost.

So i can recommend to install on every ace2 ... it can't hurt ;) (kernel + NT-APP)
[Galaxy Ace II Android Development] Dr360r:
Stock ROM provided an option to have an high or low freq screen depending on the battery level. What about providing a similar option in the performance tab in the upcoming ROM? Maybe a gaming option to have a 75 Hz display and a low power one to have it refresh at 50 Hz.
[Galaxy Ace II Android Development] giginski:
to be honest barteru on this kernel going faster then previous specially when is on data, would be any problem if I get back to previous?
[Galaxy Ace II Android Development] greeceeeee:
I had this bug when woke up phone...also 2-3 times when woke up on the bottom of the screen showed 2 lines like the screen was damaged....too many freezes for me
[Galaxy Ace II Android Development] ace2nutzer:
i don't understand .... :)

with 20th + NT-APP 1.6.5 ??

What's you LCD Type ?

What issue do u mean ??? The half white circle on the right side ???
[Galaxy Ace II Android Development] giginski:
i ment that since i got lastest kernel battery goes down faster then kernel before so my question is: would be any problem if i go back to previouse kernel ?
[Galaxy Ace II Android Development] faroukovic3:
[MENTION=5840412]ace2nutzer[/MENTION] I use the 06/11 build because it haves much governors than the last build which haves only 4 and no one of them work for me at a frequency more than 1000 Mhz :confused: But I'll install it now like u said , thnx .
[Galaxy Ace II Android Development] artur1131:
Guys, in your devices, blackscreen bug really dissapeared? Im using newest kernel and it still occurs.
[Galaxy Ace II Android Development] LyrixTheDj:
Had not this bug since TC 07082014 rom build, especially on subj kernel. All goes fine. But, i got a one reboot at 1200 mHz after 12 hours uptime, set now to 1150 (interactive|sioplus).
[Galaxy Ace II Android Development] artur1131:
Forget what i was talking about blackscreen bug. My ace is just piece of ****. I installed stock rom and now when i try to go into recovery - i have blackscreen(wiped everything). Im just rebooting my phone into recovery for sth like 20 minutes. It works (i can use options blind)...

I think that ill say goodbye to this **** and it will go for a meeting with wall, floor or sth else.

wow, though guy, he kissed the wall and its still working (hahaha working - u get it? :D)
[Galaxy Ace II Android Development] ace2nutzer:
@up

hahaah but the poor ace 2 :laugh:

Try to do clean install like: full 3-parted.. sometimes for some hardly problems it will help.. The Wall can't help :D

@ all

Sorry Guys i forgot to announcing the newest Build release.. it was late in the Night :eek:

Actually latest Build is 20141116 ...

Try it, abb-charger finally works perfectly.. even i increased a bit the battery lifetime.. thanks again [MENTION=1130928]doctormord[/MENTION]

@ all again...

Please don't report Bugs for old Builds ! That's really useless for development here.. Also the Bugs what u are reporting probably already fixed in the latest Build...

and about the Stabilty.. i can only improve the Stabiltity if u ALL will use always the latest kernel.. then i can debug...

For me it works fine.. therefore i can do nothing... but if u use also the latest build.. and i see.. or u saying with the latest Build u have more reboots for ex. @ 1,2Ghz.. then i can do something ... the same thing for Blackscreens if there are any.

Also it's a really bad Choice to say: "I use an older Build bacause it have more Governors ! " :)

U relly don't need to worry about that.. I've removed it because that Governors was not adapted to Ace2 ..... i'll only add Gov. what are perfectly tuned on Ace 2 ...

[MENTION=1130928]doctormord[/MENTION]

Charger works perfectly on latest build.. the phone shutdown correctly @ 3,27 V on 0%

I don't have such drops.. i sugggest to do this:

delete this file: /data/system/batterystats.bin

Then, use the Phone till 0% and charge it till 100%.. than use it again till 0% .. then your Battery indicator is calibrated..

Charge the Phone in online Mode for that calibration ...

Important: Don't reboot and don't do partially charging .. for ex.: connecting to usb port... for transfering files.. use during the calibration your sdcard with an sdcard reader .... ;)
[Galaxy Ace II Android Development] supachris:
Battery consumption is now very low again. Even with conservative governor the phone is very smooth at 200MHz/1GHz. Mega thanks [MENTION=5840412]ace2nutzer[/MENTION] for this great work.

Greets, Chris
[Galaxy Ace II Android Development] eaque:
Hi guys!

I don't know if it's the right thread, so sorry if it's not!

I tried different CM 11 files for codinap (I own a gt-i8160p) and I have one problem: mobile data don't work. It works with Samsung's stock JB but it won't work when I flash CM11 (Rox's file or Ace2nutzer's file with or without his kernel). What should I do?

Can I try a codina file?

Thanks!
[Galaxy Ace II Android Development] matthias1976:
set right APN !?
[Galaxy Ace II Android Development] eaque:
Ok... I might try this... *facepalm*

Thanks! :D

Edit: now it works! Thanks!
[Galaxy Ace II Android Development] matthias1976:
every time u charge till 100% the betterystats.bin is written new.

so it useless and unneeded.

in beatterystats.bin only is saved which app is need what amount of energy -> this is what is shown in andriod preferences when u got to battery.
[Galaxy Ace II Android Development] :
I have all the time random reboots on newest version of this kernel. I come back to 20141113...

Gov: Interactive

Min. 100MHz

Max. 1000MHz

I/O Gov: SIOplus
[Galaxy Ace II Android Development] h3llrais3r:
Is this still present in the last build of 20141116?
[Galaxy Ace II Android Development] BlueZ-:
Yes, sometimes min freq autosets to 400 Mhz... Anyway I can confirm very smooth even with conservative governor

[Galaxy Ace II Android Development] MarquesYOLO:
I don't know why but i don't feel better battery life, i don't know if is battery problem because i change settings ad less as possible.

Rox last build and last kernel. Interactive+noop 800-200.
[Galaxy Ace II Android Development] surfboardcm:
hello. i've installed the latest kernel. I set the max cpu speed to 1000mhz, and i get constants reboots. When it came to default 800mhz everything smooth. Do I need to change anything else? I only go to the processor speed.

thanks
[Galaxy Ace II Android Development] :
I have the same problem with max. 1000MHz CPU speed. I came back to version from 13.11.2014 and waiting for next build of this kernel...
[Galaxy Ace II Android Development] ace2nutzer:
Ahh now i see the "problem".. according to your screenshots .. the biggest problem is you bad Signal Quality !

U've poor Wifi Signal. + probably poor 3G Signal ...

According to my experiences about that things.. i can say .. badly wifi Signal don't drain the Battery much more.. (but slightly difference)

BUT

A badly 3G Signal drain the Battery very fast ! And much more if u're using your Phone with 2G/3G (Automatic) then the Phone switch to often between 2G and 3G .. that drain battery very much !!

To Avoid this, and for me..:

@ Home I've badly 3G Signal... I use Wifi + 2G only..

But when i'm outdoor then i use static 3G + mobile data.

Try this.. u'll see a big difference :)

@ all with random reboots..:

I've accidentally re-enabled Nt-APP permissions :D

To fix wrong Voltages for 1Ghz+ go to Nt-APP and set CPU Voltage @ -12.5mV
[Galaxy Ace II Android Development] MarquesYOLO:
@up

Ok so:

At home: WiFi on & switch 3g to 2g.

Outdoor: WiFi off & switch 2g to 3g.

And i should feel better battery life, isn't it?

Thanks.
[Galaxy Ace II Android Development] ace2nutzer:
@up

exactly ! Make sure that is static.. and not automatic 2g/3g .. the switching cost battery.

But: if u've at home better signal on 3G.. then u should use even 3G @ home ...that's it !
[Galaxy Ace II Android Development] MarquesYOLO:
Ok, but i think that i don't have bad 3g signal but "general signal" at home. When i'm outdoor 3g signal is good, when i'm at home i have the problem that i heard callers bad, for example.

Is there any app that could change these settings automatically? I tried Tasker before but don't work properly.

Thanks again.

PS: Whit CM11 profiles, i can turn on/off data mobile but i can't switch 3g/2g (or i don't know how.)
[Galaxy Ace II Android Development] ace2nutzer:
i shouldn't cause any problem if u'll use proper NT-APP Version according to the changelog on the Thread here :)

But are u really sure ? latest Kernel has only 50Mhz for WS2401 .... so it should save some power.
[Galaxy Ace II Android Development] greeceeeee:
Yes, WS2401

yes the circle on lockscreen I think it has something to do with orientation
[Galaxy Ace II Android Development] Dr360r:
With the latest GMS (Google Play Services) 8.3.0.0 it started awfully crashing again.

Fire up Google Maps to watch it repeatedly crash when trying to get position via Wi-Fi/cells triangulation.

Neither GPS does longer work.

Uninstalling Google Play Services and reinstalling it and cleaning caches via CWM Recovery didn't help either.
[Galaxy Ace II Android Development] ace2nutzer:
try this:

http://xdaforums.com/showpost.php?p=63420161&postcount=3618

got to settings, privacy, search for google play services (maybe u need to check "advanced" from menu) and make this ...
[Galaxy Ace II Android Development] Dr360r:
Seems fixed as for now, thanks. Both keep awake and wake up were denied with GMS prior to 8.3.00 and though it gave error messages every now and then it worked.
[Galaxy Ace II Android Development] manthes:
I have a reboot with latest kernel (and another one with previous).
[Galaxy Ace II Android Development] RyxeL:
can't download novathor setting from dev-host
[Galaxy Ace II Android Development] Dr360r:
Try from a desktop browser.
[Galaxy Ace II Android Development] ace2nutzer:
yep, it's broken.. i've it just reuploaded again ... (same version, but compiled with latest software --> java, ant etc..)

Also reuploaded kernel 20th... (same version, but compiled with latest software, clean build)

Yes, are u undervolting ? Even if it's only -50mV on cpu ...

because according to the log your CPU makes miscalculations ... and because of this u've now broked filesystem on /data partition. (that's why it reboots ---> panic)

How to fix ?

- Easy: Remove Undervolting.

- wipe cache from settings ---> storage.

- reboot to recovery

- wipe cache

- make cwm backup

- format /data partition (ext4) (not wipe data!)

- advanced restore

- restore only /data partition

- reboot to the system

- reboots are now fixed ! ;)
[Galaxy Ace II Android Development] RyxeL:
still can't download it. press the download button and just redirected to download page again
[Galaxy Ace II Android Development] manthes:
Yes i have it to -50mV. The problem appeared with previous build.

I will try the solution.
[Galaxy Ace II Android Development] ace2nutzer:
Nope, it works now ...

Try once again:

Still having reboots with latest kernel+novathor while traveling by train and using 3g.

I'll install this recompiled build, but won't be able to test it while traveling until sunday evening...
[Galaxy Ace II Android Development] ace2nutzer:
Okay... if reboot occur, just post last_kmsg (u can find /proc)

Don't reboot manually again after the phone reboots, otherwise the log from previous session (with the reboot) , is deleted and i can't help.
[Galaxy Ace II Android Development] Matteo90:
Here's the log from today, hopefully it'll be of help!
[Galaxy Ace II Android Development] ace2nutzer:
it looks very bad ... and unfortunately i can't see what is broken. (log is correct)

But for sure also filesystem corruption ... u can try to make sdcard0 and 1 and cwm backup ... and then format everything ... and then restore your cwm backup + the files for sdcard0 and 1.

I think it'll fix the problem of 99%.

Follow same instruction i wrote before for manthes... but as i said u will need full formatting .. also both sd cards !

The sdcards u'll need to save on computer ... for later restoring if u want.

But beware: don't format /modemfs ....

And format both sdcards ONLY over cwm as vfat !!

If u need to repartition your sdcard .. because of ext4 partition for link2sd ... do this AFTER u've format over cwm !

Good luck ! ;)

EDIT: What about CPU or GPU UV ??
[Galaxy Ace II Android Development] Culateralligator:
This afternoon my phone has started lagging as it was JB Stock while using apps.

When I saw this message, I checked Google Play Services and it wasn't updated yet. But after experiencing now this huge lag I've checked it has just updated to v8.3.0.0.

I've wiped dalvik and cache, just in case, but that's not the problem.

Anyone else with this issue?
[Galaxy Ace II Android Development] miryn:
Something weird with that all '2D in games' situation.. On latest kernel, in 'impossible game' there's perfect smooth for about 7seconds and then for 3 seconds there's that 'glitching' (forgot that word) and it happens again, 7 seconds- perfect, 3 second- crappy, and again and again..

wtf
[Galaxy Ace II Android Development] Dr360r:
8.3.00 didn't cause lag in my case. Google Play Services just started crashing again while surfing and positioning. Solved by turning Keep Awake in privacy settings for Google Play Services from Denied to Allowed and now everything is fine.
[Galaxy Ace II Android Development] ace2nutzer:
We now that, no need to write this several times :o

As i said, it's maybe fixed with an ROM Update ... just sit cool and wait ;)

btw: only WS2401 is affected, .. here on S6D i play this game every day without any lags :)
[Galaxy Ace II Android Development] miryn:
I'm not saying once again that there is a problem with 2D, but just odd '7 seconds' depending. But ok, whatever..
[Galaxy Ace II Android Development] Culateralligator:
I've tried that but it doesn't work. Every time I reboot appears Alarm Manager running all the time. I've uninstalled Whatsapp but it hasn't solved the problem, as seen in the pictures attached.
[Galaxy Ace II Android Development] Culateralligator:
After wasting some hours trying to figure out what is wrong with no success, I've restored a backup. Immediately GPServices has updated to v8.3.0.0 but now there's no issues at all.

Error while updating?.... Whatever...

Conclusions: healthy often do backups.

PS:I take the opportunity to comment 2015-10-11 kernel's working perfect for now. Smooth and 24 hours of battery with 6 hours of screen on.
[Galaxy Ace II Android Development] Matteo90:
I did everything you suggested, hopefully it'll work. :fingers-crossed:

By the way, I don't do any cpu or gpu uv, I only enabled anagain3 in audio and storage swap, as well as disabled bln and bln blink.
[Galaxy Ace II Android Development] greeceeeee:
On previous post i said about freezes with last kernel,the problem was the fuc...ing buggy facebook that cause freezes....Now I have problem again with charging,it takes too long and it has big difference on offline chargine and when i enable the phone with charger plugged in.. :(

For Facebook try version 5.0. It is old but it has almost everything and you don't need Facebook messenger
[Galaxy Ace II Android Development] ace2nutzer:
Offline Charger:

USB (PC): max. 500mA

USB Charger and AC: max. 700mA

USB PC, USB Charger and AC: 700mA by default (but u can change over NT-APP)

(i suggest to don't use more than 700mA)
[Galaxy Ace II Android Development] gepel:
Offline charge bug is still there. During charging some times the phone boot up. WS2401.

Is there anyone here playing game Summoners War? Sometimes little weird black screen appear on my screen, its like the graphic effect of the game broken. But, the game is still going on, no crash or smth. Is that kernel problem? S6D here.
[Galaxy Ace II Android Development] Dr360r:
By doing a major tweaking in Privacy settings i managed to achieve a lag-free experience. Only detailed maps in Google Maps now lag, low detail ones are smooth. You need to smartly deny everything that might load the CPU up (and steal juice), such as Keep Awake and Wake Up in apps like Whatsapp, Messenger and Facebook and Location in other apps you feel they don't need it. Look at what privacy item is most used in Advanced settings of Privacy and guess what needs to be denied.
[Galaxy Ace II Android Development] greeceeeee:
this on the bottom of the screen do you think it is lcd's problem or kernel's? It appears sometimes when I wake up the phone and disappears with screen off and screen on
[Galaxy Ace II Android Development] Culateralligator:
I had that line with 66 MHZ kernel.

I've tried October's 11, 14 and finally 20th kernels without that line appearing on the screen.
[Galaxy Ace II Android Development] greeceeeee:
I have it with the latest kernel
[Galaxy Ace II Android Development] miryn:
Damn i thought it's Vanir's problem.. I have the same.
[Galaxy Ace II Android Development] VRDRBR:
have i too on latest kernel
[Galaxy Ace II Android Development] ace2nutzer:
okay it looks like that on some LCD's some Parameters/Values don't work properly ... it has also something to do with the LCD Quality.

I'll make later new Build with different video.modes .. but still stock LCD Freq of 50Mhz ...

Such lines can happen if:

LCD is half broken

too high LCD Freq

wrong video.modes

low lcd quality

wrong lcd density value on build.prop (maybe)

It has almost nothing to do with the ROM itself... except of build.prop Values.

So u can check and make sure that u've that Value in your /system/build.prop:

ro.sf.lcd_density=240
[Galaxy Ace II Android Development] miryn:
lcd_density=240 on a2? pls.. :)

Situation began to appear (+ -) a month ago, afair, when the bottom of the screen seemed pretty much to not responding sometimes
