Same here :)

just now, i've got 2 times blackscreen for about 45 - 60 seconds.

Get some notification from app, then when i wake the phone, i have to wait 45-60 seconds(waiting the blackscreen dissapear)

I also still have blackscreen issue at cwm recovery.
[Galaxy Ace II Android Development] ace2nutzer:
Good good guys!

Btw only one user with blackscreen on p1 build?
[Galaxy Ace II Android Development] seanmalto:
Maybe just me :p

at cwm recovery (often) and ussualy have to wait (45-60seconds) to wake up.

s6d lcd driver.
[Galaxy Ace II Android Development] ace2nutzer:
I'll make later new build.. But If anyone have also blackscreen issue so pls let me know. (On latest p1 build here)
[Galaxy Ace II Android Development] wolfensg:
I'm testing this kernel at the moment (I had similar problems on WS2401 as most of ppl have on S6d (faulty chip?) - issue here -> http://xdaforums.com/galaxy-ace/ace-2-help/black-screen-bug-ws2401-lcd-ace2-t2972752

Currently looks stable, fast with lots of RAM and... I don't have a blackscreen bug (well at least not in the last hour ;) will post later some details as a edit to this post.
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!

Changelog:

20150128:

2. Attempt to fix Blackscreen Bug

Optimized I/O Speed ----> 30% more Speed

Fixed tiny I/O Bug from previous Build

Optimized RAM Management a bit more

Better Battery Lifetime

Updated 01optimization File

More Smooth

INFO:

This Build is useful for all, not only for s6d users with blackscreen bug !
[Galaxy Ace II Android Development] proficus:
Great!

Stable at 1250 mhz!
[Galaxy Ace II Android Development] seanmalto:
I can confirm now that with latest build(20150128) there is no more blackscreen issue with sleep-wake quickly.

Even when i do multitasking, and some notification come from any apps then i force to sleep the phone and wake it quickly, blackscreen doesnt appear :)

The one thing that may still present is blackacreen when reboot into recovery, its fine i think. I just doing some backup and also flash latest kernel if needed when entering recovery, so its only will be a big problem when i would like to do a fresh install that i have to entering cwm recovery for many times.

Also Stable at 1200 Mhz

Thanks for your great work sir :D
[Galaxy Ace II Android Development] manthes:
Are you thinking to make a universal kernel? I want to try but i it is a big problem because of cwm blackscreen
[Galaxy Ace II Android Development] ace2nutzer:
This is still very good !! Can u pm me later about fixing black screen in cwm if u like .. if yeah, just tell me wich kernel do u use/need .. i'll make some test builds... ok ?? ;)

To be honest ATM no .. but i plan maybe at the end when we've here an final build to make builds for all 4.1 4.2 and 4.3 Android Versions ... because it's really annoying job to make for every release so many builds and upload it ... that take too much time .... But i think i can fix the blackscreen bug also in cwm .. just be patient :highfive:

Using latest version right now @1,2GHz no random reboot. It's the first time running my CPU more than 1GHz without reboot since I've been using your kernel. Perhaps my CPU quality isn't good.

Experienced delay about 30 sec when turned on the screen. My phone was fully charged and still connected to power bank when that's happened.
[Galaxy Ace II Android Development] PolishVodka:
His kernel (ace2nutzer) and philz recovery (Bx16) for 4.3 Roms, but I don't have phone to test it, so if anybody can test:

[Galaxy Ace II Android Development] aish8la:
I had some memory management issues with latest build. Google now launcher redraws occur after using chrome or other apps. So I'm back on 20150127 p1 build in which I haven't noticed any memory management issues.

Sent from my phone
[Galaxy Ace II Android Development] arha1:
20150127 work's all fine for me. :) Now that there is no more lagging I would try to overclock my CPU. Which app do u use for that? Thx. :)
[Galaxy Ace II Android Development] bidug:
Settings > Performance > Processor

Uncheck the box "Set on boot" until you find a stable value !
[Galaxy Ace II Android Development] arha1:
I cannot find that point in my settings. :confused: Or are u using an app for that?
[Galaxy Ace II Android Development] bidug:
what ROM are you using ?

it's right at the bottom, between "Superuser" and "About phone"
[Galaxy Ace II Android Development] bebolint98:
You need to click settings>About phone and click about seven times to build number and after it appear in setting menu the performance point.
[Galaxy Ace II Android Development] arha1:
Thanks, bebolint89, that hit was the right. :)
[Galaxy Ace II Android Development] wolfensg:
Unfortunately still I have black screen bug on this kernel. I've reverted to the old kernel by Polish Vodka. :crying:
[Galaxy Ace II Android Development] seanmalto:
Unfortunately I've got blackscreen again.

dont know what the problem is. Still the same, its about sleep then wake up the phone.

Now im back with universal chrono kernel r2.14.5

there is no blackscreen, recovery working well too with chrono, I use twrp ext4 for recovery.

I'm sorry, but maybe you can put something from Chrono kernel to fixing the blackscreen at your kernel

thankou :)

please check also if blackscreen bug still appear ... if yes, post pls your lcd driver.. (ws2401 or s6d) and write here wich build u need...for example: codina f2fs ..... then i'll make in neartime a testbuild based on latest build here in order to fix blackscreen issue. :)
[Galaxy Ace II Android Development] arroyo:
I have ws2401driver, latest CM, kernel codina 20150128 f2fs and this is best kernel I had. Full stable at 1150. Checking 1200 now. I have not seen blackscreen bug since like half a year.
[Galaxy Ace II Android Development] seanmalto:
Is your kernel support for twrp recovery? If doesn't then i will flash cwm recovery.

Hopefully with your latest kernel there is no blackscreen anymore.

I will report after flash this latest kernel :)
[Galaxy Ace II Android Development] zizoumadrid:
I want to give a try to this kernel but till now what is the best build of cm11?

the last build i'm used is cm11 07/08 from rox

01/18 by ace2nutzer is the best ? And what is the différent between this 2build thanks
[Galaxy Ace II Android Development] MrBlackCore:
Personally I never had a rom better than ace2nutzer`s 01/18 + his latest kernels = perfect 4.4.4 phone
[Galaxy Ace II Android Development] hiemz:
[MENTION=389932]Ace2[/MENTION]nutcer, are you have a plan to build a kernel for cm 12? or build rom cm12 maybe :D
[Galaxy Ace II Android Development] pedroleon99:
I vote for cm12 xD but I think we are OT there
[Galaxy Ace II Android Development] DusBekas:
Version: 20150130 f2fs

LCD Driver: ws2401

Stable [MENTION=4867107]1100[/MENTION]MHz, had no random reboot @1150MHz or [MENTION=1348102]1200[/MENTION]MHz but not too stable because perhaps it made some apps not worked properly and crashed . I'm not sure that's because the clockspeed or not, but with 1100MHz everything's working fine for me.

Then talking about RAM management, I think it's pretty good. The launcer (apex) never redraw, and I just had issue once. When I used my phone the screen was unresponsive then status bar disappeared finally the screen is locked but still on (I don't know what this issue called).
[Galaxy Ace II Android Development] bebolint98:
[MENTION=5840412]ace2nutzer[/MENTION] why I can't play the YouTube videos in stock cm browser,chrome or other browser just in UC and dolphin I only have blackscreen.
[Galaxy Ace II Android Development] ace2nutzer:
@up

YT vid playback don't work in browser with ART Runtime. It works only with Dalvik OR just with the Youtube App perfectly...

i use "OG YouTube" and i can watch even @ 720p :)
[Galaxy Ace II Android Development] bebolint98:
Ok, thanks, I also found this OG youtube about one hour.
[Galaxy Ace II Android Development] hiemz:
really? so how can i ask to him? may you make a thread for us?
[Galaxy Ace II Android Development] wolfensg:
Still blackscreen when trying to unlock. I used the kernel build from 30th Jan. I have WS2401.
[Galaxy Ace II Android Development] ace2nutzer:
Thx.. i'll build some test builds in order to fix that bug when i've time ... just check from time to time here the postings.. because it's not official release with announcement in Thread Title.. and without changelog till we found the fix.... because also the test builds are always based on latest official builds here ;)

btw: next official build is coming with Huge Improvements... especially in Ram Management ;)
[Galaxy Ace II Android Development] Samaramabezkol:
Anybody have problem with calling? After update to 20150130 dialing takes about 30 sec but sometimes dialing doesnt works at all. Incoming calls not always come up to me. Maybe its coincidence and my GSM provider has brake-down bu its weird because issue showed after updating.
[Galaxy Ace II Android Development] ace2nutzer:
@up

this is maybe possible.. ram management is still not perfect and sometimes when ram is very full, the system is unresponsible.. soft-reboot also possible. It's fixed in next build ;)
[Galaxy Ace II Android Development] Samaramabezkol:
I have rebooted few times and it still the same.

BTW. Me too I cant watching yt on Browser. I have dalvik. On older versions I could watch.
[Galaxy Ace II Android Development] ace2nutzer:
Well, then maybe it's problem with your provider / simcard.

About that Live Streaming things: I think u all already know now, it's just cm sources bug ... and that bug will stay forever... just this.. all the other things is perfect :o

[MENTION=5840412]ace2nutzer[/MENTION]

Is it normal, that i have a problem with changing minfree settings by init.d ? Is Your kernel just has higher priority to some settings?

My init looks like that:

#!/system/bin/sh

#chmod -R 755 /system/etc/init.d

echo "xxx,xxx,xxx,xxx,xxx,xxx" > /sys/module/lowmemorykiller/parameters/minfree;

xxx-numbers
[Galaxy Ace II Android Development] ace2nutzer:
try without the red marked...

I don't think it's a Problem to change it ... Wich ROM are u using ???

By 18/11 ROM there is a sleep 90 command... that means for init.d scripts they where executing after some seconds after fresh boot.

U don't need to change permission.. just echo ...... try again ;)
[Galaxy Ace II Android Development] PolishVodka:
His kernel for stock JB:

http://www.mediafire.com/?9vfhx8s3cvbyf9n
[Galaxy Ace II Android Development] miryn:
I tried without semicolon at the end and without any permission at the beginning but unfortunately still no results..

I'm on Spirit rom with Your latest kernel. Inits for fsync, VMs, etc. works well, only that one doesn't want to cooperate AAND it worked on Spirit's kernel before i installed Yours.. :confused:
[Galaxy Ace II Android Development] zizoumadrid:
can someone share some screenshot of battery use ? i think i had battery drain

thanks
[Galaxy Ace II Android Development] ace2nutzer:
Thank u for compiling :)

But i hope u didn't build the Kernel from the latest commits ... because actually i'm working on RAM Management and the Phone freeze after some seconds ....

Till this commit is everything OK:

7cff59bd7f80725a900068d9b9a960df3f1749e0

EDIT: Fixed compiling error + Freezing :D

I don't know about spirit .. check permissions of the file: minfree ... it should 644 or root:root rw-rw-r--
[Galaxy Ace II Android Development] miryn:
Are You sure Your kernel doesn't have highier priority (or somethin) for this settings, cuz like i said, that init worked before I install Your kernel (so it's not rom fault)..:confused:

Permissions also doesn't change antyhing.
[Galaxy Ace II Android Development] ace2nutzer:
yeah, sure :) why not ?

Post pls screenshot of minfree file + their permissions.. and show me how du u do the echo ...

It's better if u just post the wohle command here... maybe a little mistake ...
[Galaxy Ace II Android Development] miryn:
Ok, i tried like that:

and that:

Init's permissions:
[Galaxy Ace II Android Development] ace2nutzer:
@up

that looks good.. but did u checked the permission of the minfree file itself ??

It should have: root:system and 664

for me it works... tested right now
[Galaxy Ace II Android Development] miryn:
Yep, i have the same permissions, Idk wtf..

One more question..: Agressive power Saving, Zram's Disk Size 623MB (99%) and SD read ahead 1024 are DEFAULT (Your)kernel's settings?
[Galaxy Ace II Android Development] ChronoMonochrome:
You're right, i first tried to edit it from NT app - but for some reason it's showed me incorrect voltage index (I think it set 0x16 doesn't matter which idx I select). Just tried to edit this file manually, and now it's ok.

UPD,

Nope, just checked this file after editing it via NT - when selected 0x18 it set 0x12 instead :/ seems as NT app bug.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah.. 0x12 is too much low for Vape.. i suggest to don't undervolt more than 0x18.
[Galaxy Ace II Android Development] fluffi444:
Yeb - as Ace said the NT app shows only numbers... 24 = 0x18 and 25 = 0x19 etc....

The "bug" is if you deactivate this setting in NT app it NOT goes back to standard... it stays at the last setting which was activated former...

But maybe then an "other" vape was taken and not the one in the file?
[Galaxy Ace II Android Development] ace2nutzer:
It is no matter at wich Value it stays after disable.. the important thing is that this feature will disabled...

u can check this here: /sys/kernel/abb-codec/lpa_mode U will see: Enabled [ ] <----- that means OFF and: Enabled [*] <---- ON / activated ! When it is OFF, then on screen off will be used the actually Vape for GPU.
[Galaxy Ace II Android Development] ChronoMonochrome:
My bad ... so I really misunderstood - I thought selected 18 means 0x18(and I did not take into account the fact that in NT are not present 1a-1f indices) ...
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !

Download Post #1 and Changelog Post #2 !

[MENTION=5210243]exodius48[/MENTION]

In this new Build i have disabled the LPA by default.. please test this Build if u get anyway Blackscreen after wake up the Device.:angel:
[Galaxy Ace II Android Development] exodius48:
Wow, no blackscreen so far even on cwm. :highfive:

For offline charging , not yet tested it.
[Galaxy Ace II Android Development] nikolas1274:
How can we use the "Full BLN Support with Blink" because it works only when it is on charge, some time ago you told that we need tasker, can you explain it when you have time?

thanks
[Galaxy Ace II Android Development] Glpcha:
"restore settings on boot" has to be ticked if you want to keep the desired governor after booting your phone.

Sent from my mobitel
[Galaxy Ace II Android Development] S.AMU:
For the moment BLN needs something which makes a wakelock, otherwise the phone goes to sleep. To have a wackelook you have different possibilitys. For example you can plug in your phone or activate sweep2wake or d2w.

But the best solution is still tasked with an rule that turns on a wackelock when there is a notification and turns of the waxkelock when you turn on the screen.
[Galaxy Ace II Android Development] nikolas1274:
Thanks i will try the guide from your signature
[Galaxy Ace II Android Development] matthias1976:
BLN

Have u guys tried ButtonLED here from forum !!

Im still on march build but BLN with ButtonLED works very well for me.

Ace2nutzer said ButtonLED wont work. we spoke over it months ago.

Install ButtonLED, load it, it will ask for ButtonLight file, choose first one, enable ButtonLED in Accessibility <- very important without no work !!

accept SuperUser access !!

works for me very well but im on old build !! try if u want.

Tasker cost money, or am i wrong !?

maybe Llama is alternative ?
[Galaxy Ace II Android Development] str3tch72:
Is there any script or line in Terminal to overclock GPU?
[Galaxy Ace II Android Development] ace2nutzer:
At first: how much reboots did u have till now with 1,3 Ghz ?? This is very interesting me :D

Actually GPU runs static @ 400Mhz.. if u just enable AutoBoostGPU u will have min.: 400 max.: 600Mhz ..... here i can really suggest to don't oc more than 600 - 650MHz.... because i don't know how stable is GPU... And at least don't forget u are already over the specs... max. clock is 1,2Ghz for this Board..... ;)

To enable AutoBoostGPU:

echo 1 > /sys/kernel/mali/mali_auto_boost

or without Autoboost.. then just disable it again with echo 0 > ..... and type this command for static 600Mhz:

echo 600000 > /sys/kernel/mali/mali_gpu_clock
[Galaxy Ace II Android Development] str3tch72:
[MENTION=5840412]ace2nutzer[/MENTION]

It was strange, because reboots occurs when I tap "hibernate all" shortcut on launcher. Really strange. Anyway, thanks for script :)
[Galaxy Ace II Android Development] ace2nutzer:
@ up

therefore your Phone is stable @ 1,3GHz ?? If yes, u have big Luck !!!
[Galaxy Ace II Android Development] str3tch72:
@up

YES :D
[Galaxy Ace II Android Development] BlueZ-:
And what about battery?
[Galaxy Ace II Android Development] ace2nutzer:
Actually impossible.. to see this.. because i'm calibrate the Batt. voltages.. even then you Phones needs to charge and discharge about 3 times till battery full gauge is calibrated...

Latest Build is even not accurate full gauge.. but i hope next build will be accurated...

With this acually Build u can use the Phone @ 1% for others 30 - 45 minutes :D (playing music on screen off)
[Galaxy Ace II Android Development] ace2nutzer:
really strange.. but what is the problem ?? After reboot the values are still kernel default ?? did u tried directly over term. emulator or ADB ????

Yes is right ..... actually .. but next build is different ;) U usually don't need to change this.. it's already optimzed by me.

What did u use for FSync ?? :)
[Galaxy Ace II Android Development] miryn:
Yep, after reboot the values are still kernel default; what stranger, in the same init i added own values for debug level and parameters/adj and they working :mad:

Btw. About FSync, i use dynamic (echo 2 > /sys/kernel/fsync/mode)
[Galaxy Ace II Android Development] ace2nutzer:
I really don't understand.. there is really no reason why it shouldn't work ..

But i suggest to u to let Fsync @ 0 (ON) Kernel Default.. because OFF and Dynamic u will destroy the whole Phone after 1 Week. With every random reboot and with every app crash u'll loose data, and may also filesystem curroptions.

I've tested this personally because i also don't believe that, but it's true.. also by app FC the Data of the app is lost.. it happens to me with the Stock Browser .. after FC .. all my saved sites in favourites where away .. really bad...

But the difference is big in performance with disabled Fsync. :)
[Galaxy Ace II Android Development] miryn:
Hmm I agree! Today i had a phone(dialer?) FC and after that all call history was lost.. I'll set it back to default.

Btw. I set the minfree in PerformanceControll and then tick "set on boot". It holds my settings, so i guese i must be happy with that :p
[Galaxy Ace II Android Development] Samaramabezkol:
But on 20150128 or 20150127_p 1 (I dont remember) I could watch yt on Browser. U can ask my friends :P

How can I back to older version of kernel?
[Galaxy Ace II Android Development] ace2nutzer:
New Build is up !!!

Changelog:

20150201:

Increased overall Performance

More Smooth

Better Battery Lifetime

Much more responsive

Completely reworked Ram Management

Many Kernel Tweaks

Support for NFS V3 + V4 Client

Completely disabled zRam

Revert: "Backport LZ4 zRam from 3.5 Branch" (it was too buggy)

Enhanced Multitasking Support

-----------------------------------------------------------------------------------------------------------------------------

I don't know what i should to say for this Build.. much work ... and i hope now that is an nearly "Final Build"

Enjoy this (hopeful) perfect Build ....

Notes: U don't need to change things like minfree Values etc .. Kernel Default Values are already highly optimized by me !

Just set your max stable Clock for CPU and GPU .. and u are done ! Just enjoying ..... :fingers-crossed:
[Galaxy Ace II Android Development] zipperX:
Why you remove zram and revert lz4? I think it's perfect
[Galaxy Ace II Android Development] Samaramabezkol:
Hey! U made a mistake! You upload kernel for codinap as a codina and now my phone is rebooting after PIN. ext4 of course :)
[Galaxy Ace II Android Development] shaqman89:
Did anyone experience losing some application after upgrading to 20150201?
[Galaxy Ace II Android Development] Danko Jones:
yes, Antutu benchmark is gone and cannot be installed again from play store "Fehler beim Installieren von USB-Speicher/SD-Karte".

Don't know if other Apps are affected too.
[Galaxy Ace II Android Development] shaqman89:
It affected around 6 apps for me, and for now I'm reverting back to previous version.

I'll check more when I'm at home, but I'm suspecting it's related to apps that's stored in SD card
[Galaxy Ace II Android Development] LyrixTheDj:
Sh*t happens.

I was installed "codina" ext4 (without NFC) a few minutes ago. File is correct for codina.
[Galaxy Ace II Android Development] bebolint98:
So the latest "codina ext4"is correct for codina?Because I install this and now I can't install app from play store because it's write "can't install to USB-storage or sd card".
[Galaxy Ace II Android Development] MarquesYOLO:
Same problem with one app here in latest version.
[Galaxy Ace II Android Development] Samaramabezkol:
So I dont know what happend with my phone. 20150130 is stable but 20150201 is rebooting.
[Galaxy Ace II Android Development] Danko Jones:
After reverting to 20150130 Apps are back again. I suggest to use 20150130 until Ace2Nutzer has fixed this issue.
[Galaxy Ace II Android Development] LyrixTheDj:
Yes, have this issue, on f2fs to. But no reboot, stable at 1150 mHz.
[Galaxy Ace II Android Development] ace2nutzer:
Sorry guys.. I think i messed smthg up I'll re-build .... I'll delete the uploded 0201 and wait till a new build is up.. Same date.. I'll inform u
[Galaxy Ace II Android Development] MrBlackCore:
well u didnt delete it and now my phone is rebooting like crazy...
[Galaxy Ace II Android Development] ace2nutzer:
Yeah, i had no time for that.. but u also didn't read my post ... i wrote when i upload working version, i'll inform u. ;)

EDIT:

STATUS:

Uploaded ! ... but only on dev-host ... i'll upload it also on ftp-server if there are no major issues in this build !

Changelog: Same like Yesterday 0201 !! ;)
[Galaxy Ace II Android Development] aish8la:
Yeah same happened for me for all the apps in sdcard. Also since 20150201 build my phone reboots when I launch poweramp music player, I tried recent 20150202 build and still phone reboots when I launch poweramp. Now I'm back in 20150130 build and poweramp works fine.

Sent from my phone
[Galaxy Ace II Android Development] heldix:
I am very happy with the 30.01.2015 build. Everything works fine. I dont understand why u disabled Z-Ram in the next build. I think i will stay with this 30.01. because i cant imagine what can be further improved when everything is fine.

Greetings
[Galaxy Ace II Android Development] BlueZ-:
For me too, the only app on sd is desappeared and I can't reinstall it. In addition it's not possible move any app on sd
