Offline charging unfortunately still gives me black screen instead of battery animation with latest kernel. (S6D) It was working fine with PolishVodka's 09/04/15 CyanogenMod 12.1.

Other than that, I haven't encountered any blackscreens so far, but I only installed the kernel a couple of hours ago.
[Galaxy Ace II Android Development] ace2nutzer:
Okay.. i think it's theme engine problem.. also i can suggest to use the Nova Launcher Version included in the latest rom here.. because for me the latest version redrawing too often and need maybe also more RAM. To use the older Version: just uninstall the updates...

Nope, otherwise i had it wrote to the changelog or not ? ;) But it's in my todo list :)

Yes, you’re right ... it's a conflict with the standard BLN ... due to BLN Notifications + BLN on/off when battery is full... but i'll try to fix this.

I didn't faced this issue because i don't use the default BLN ... i just use it only for notifications + for battery full indicator ...

okay ... this is of course a bit annoying .. but when battery is fully charged the BLN will go on ... so maybe it's anyway not so bad ;)

Actually i'm out of ideas how to fix this issue also for u.. for sure it's possible .. but then maybe other things are facked up .. i mean blackscreen for other s6d users .. and of course annoying laggs ! So maybe better to deal with this small bug. ;)
[Galaxy Ace II Android Development] manthes:
It isn't for lockscreen bs? I didn't understand it well probably
[Galaxy Ace II Android Development] ace2nutzer:
Noo ... he just mean the BLN ... what u mean is the LCD Backlight ... ;)
[Galaxy Ace II Android Development] Matteo90:
You're right, offline charging blackscreen is not a big deal in itself, I just use it as an "ultimate test" for blackscreen bug i.e. if offline charging animation works, there won't be blackscreens when unlocking the phone either. :)

That's why I'm a bit worried, that blackscreens on lockscreen will return, just like with previous kernels. But hopefully that won't happen. :)
[Galaxy Ace II Android Development] ace2nutzer:
I think u'll not have bs on lockscreen .. and also not on cwm .. i'm right ? ;)

The main problem for s6d is that slow refreshing LCD parameters during ON/OFF ... u can see this on cwm in an dark room ... reboot to cwm and hold a look on the screen .. u'll see it blinks 2 times .. then cwm appear... But on Offline charging it blinks faster and more often .. that's why it fails ... very complicated thing. for such things s6d is really crappy LCD .. because it's buggy even if it's brand new LCD ...

U need much luck if it should work properly without any issues.

EDIT 1:

btw: i just forget to write in changelog:

the actually BLN Driver is like that in Chrono Kernel ... that means u've this options:

EDIT 2:

Fixed !!
[Galaxy Ace II Android Development] lab34:
Hello Ace2Nutzer,

just to say big thanks.

I was running previously an old stable version of your rom (maybe 11/2014) and I made the jump into the last one, with last kernel and last novathor. It's running very well ! very smooth, and better battery life.

Thank you for your job !
[Galaxy Ace II Android Development] hector_yo:
how can I enable this?
[Galaxy Ace II Android Development] ace2nutzer:
echo on > /sys/kernel/bt404/doubletap2wake
[Galaxy Ace II Android Development] hector_yo:
thx, it's working pretty good :)
[Galaxy Ace II Android Development] ace2nutzer:
Yeah, but it's buggy! Beware that when u tried this after some minutes again that it can freeze the screen .. then u've to long press the power-button..

I'll update this driver + some fixes from Chrono Kernel, then it works great.

btw: doubletap2wake for offline charging works already very well :D
[Galaxy Ace II Android Development] Eldok:
Hello,

No more black screen with lastest kernel (WS2401 LCD). :D

1000 thanks ace2nutzer ! :good:
[Galaxy Ace II Android Development] ace2nutzer:
@ all

can u pls post who of u has still any blackscreen on cwm, offline-charging or lockscreen with this latest kernel here ??

actually i only know that [MENTION=4365971]manthes[/MENTION] and [MENTION=5535372]Matteo90[/MENTION] having only blackscreen for Offline-Charging Animation ... :)
[Galaxy Ace II Android Development] hector_yo:
Is it normal that I have to enable DoubleTap2Wake every single time I boot my device?
[Galaxy Ace II Android Development] ace2nutzer:
yes... if u don't want to write that command to /system/etc/init.d/99_user

but it's not worth, because on next build dt2w will work automatically without any user interactions ;)

is updated and the sysfs interface is moved to /sys/module/doubletap2wake/parameters

and to enable dt2w with wakelock (otherwise it can freeze the screen) u need to use an script with this content:

echo 1 > /sys/module/doubletap2wake/parameters/dt2w_use_wakelock
echo 1 > /sys/module/doubletap2wake/parameters/enable

but keep in mind that using dt2w prevents the phone to go in deep sleep !
[Galaxy Ace II Android Development] Oğuzhan1907:
thanks.Fixed blackscreens problem . :D
[Galaxy Ace II Android Development] psidco:
+1 for black screen offline charging,there is no charge animation here ,anything else work perfectly i think ,the bln on battery full also work.my driver s6d
[Galaxy Ace II Android Development] giginski:
pplhi just tell me, how is with battery here vs chrono,
[Galaxy Ace II Android Development] manthes:
For me ace2nutzer kernel has better battery life. However both of them are making amazing job. Try and see by yourself which one is better
[Galaxy Ace II Android Development] miryn:
And still, horizontal 2D problems- simple "impossible game"- perfect smooth on 4.1.2, crappy on 4.4 with a2n's or chrono's kernel..

If You have S5, check it.. Maybe then you'll understand what i'm talking about
[Galaxy Ace II Android Development] ace2nutzer:
What is your LCD Type ? (u can check with latest NT-APP)

btw: exactly that game i had tested on S5 and it was not so smooth like on my Ace2 with S6D LCD ;)

WS2401 is actually not fully optimized ... but very soon :)
[Galaxy Ace II Android Development] miryn:
Yup, i have WS2401.
[Galaxy Ace II Android Development] andon0v:
good work, very smooth with CM11 :good:
[Galaxy Ace II Android Development] Dr360r:
Guys, does it happen to you that you leave your phone asleep and you notice the battery level slightly decreased when you awake it? Mine does.
[Galaxy Ace II Android Development] bebolint98:
Yes.Is also happen to me and I use chrono kernel.
[Galaxy Ace II Android Development] shaqman89:
There must be a rogue application, or bad connection.

In my case, even with bad connection, idle time really doesn't drains my battery. I could have 4-5 days of use when using it only for listening audio book.

I'm using ChronoMonochrome, right now, but I've got similar experience with ace2nutzer's as well.
[Galaxy Ace II Android Development] Dr360r:
Phone was on offline mode while it happened. Signal is perfect but i switch network on only when needed.
[Galaxy Ace II Android Development] shaqman89:
Well, on offline mode, without any use, I don't have any drain at all. But I do admit, when switching the connection on and off regularly drains a lot more battery than letting it be always on. This is especially true when reception is bad like where I am.
[Galaxy Ace II Android Development] ace2nutzer:
Power consumption is also there when phone is offline + all the time in deep sleep.... It' very low.. But.. ;)

And more lower power consumption is also when the phone is completely off...

If u want to keep the draining as low as possible u've to remove the battery from phone.

But that's not all... If u want to reduce discharging (but not completely) even more, u've to keep the battery @ 15°C. ;)
[Galaxy Ace II Android Development] Dr360r:
So it's normal.
[Galaxy Ace II Android Development] ace2nutzer:
Yes ! And the "self-discharging" is higher if the battery is older than 2 years.
[Galaxy Ace II Android Development] Dr360r:
Battery has been recently changed and spare battery has been made in early July 2015 (and it's original too) so we can definitely rule out battery wear here.
[Galaxy Ace II Android Development] xo.en:
That's obvious.
[Galaxy Ace II Android Development] ace2nutzer:
Really sure it's original ?! What was the price of the battery with and without shipment ??
[Galaxy Ace II Android Development] Dr360r:
About 30 Euros, with blister, no shipping. Doesn't look different from the one that came with my phone, and performance didn't degrade in the meantime, so i'm fairly sure it's original. Are them more expensive than that?
[Galaxy Ace II Android Development] ace2nutzer:
for 30 € it should be 99% original ... but definitely u can check this:

Of the battery u should see:

Cell made in korea, assembled in china.
[Galaxy Ace II Android Development] Dr360r:
I confirm that the screen flash issue some time after startup only happens with theme packs different from the default Holo one.
[Galaxy Ace II Android Development] Yønn:
With CM11 20150714, latest kernel 150921 and NovaThor Settings 1.6.2, I have some deep sleep problem. I cannot identify the origin of the issue.

I have BBS installed, what kind of information should I provide to investigate?
[Galaxy Ace II Android Development] ace2nutzer:
fully BBS log.... but make sure that before the BBS APP is installed as system app.

Then let run the phone for 2 hours and post the BBS log.

btw: are u using BLN ?? (because when it blinks, there is no deep sleep)
[Galaxy Ace II Android Development] Yønn:
BLN is desactivated in NovaThor settings, I don't need it.

I will post this tomorrow.

Do you need Text Dumpfile, JSON Dumpfile, logcat or dmesg ?
[Galaxy Ace II Android Development] ace2nutzer:
Text Dumpfile is enough
[Galaxy Ace II Android Development] giginski:
i think i had some problem with battery draining but when in settings -> privacy -> privacy protect -> advanced google play service i choose disable location suddenly my battery drain stoped, i hope it wont make any problems with functionality of my phone. Btw sorry for my english.
[Galaxy Ace II Android Development] Dr360r:
No worries mate, i perfectly got what you mean. Unfortunately, this means having things like Google Maps and News and Weather city based updates no longer working and having to turn it back on every time you need positioning functions inside apps and then off again when you don't want to lower your battery level (and also wear the battery by repeately charging it), not very user friendly i must say. Perhaps the key is totally deactivating location services through status bar when not needing them. I'll try this way.
[Galaxy Ace II Android Development] ace2nutzer:
actually only this is need... and nothing else:

http://xdaforums.com/oneplus-one/general/guide-google-play-services-battery-t2832525
[Galaxy Ace II Android Development] Dr360r:
I've been having them set that way long time but i still notice location polls being very frequent from that very Google Play Services (cell scan, fine location and wifi scan the most).
[Galaxy Ace II Android Development] ace2nutzer:
okay.. that depends only on your own installed apps .. especially apps that scans the location too often ...
[Galaxy Ace II Android Development] Dr360r:
I'm monitoring them and tweaking around with privacy guard, i'll let you know more.
[Galaxy Ace II Android Development] Yønn:
Here is the dumpfile from BBS:

https://drive.google.com/file/d/0B7PmjArP6P_iM2ltc0ttVnJ5eWc/view?usp=docslist_api

However, since my last reboot, i got back deep sleep again. I can consider the pb fixed, but If the problem goes back...
[Galaxy Ace II Android Development] ace2nutzer:
it was caused by kernel-wakelock "sva" ... this is smthg like "sia" and it's usually active when an app can work even with screen off... for example:

Apollo music player, OG-YouTube, or other such apps..

Right now tested with OG-Youtube .. and then i had also "sva" in BBS ---> Kernel Wakelocks.

So maybe u didn't close the app properly ...

What is also recommended: disable all

receivers

for OG-YouTube ... with "Autorun Manager" or other app like "disable services" or what ever. ;)
[Galaxy Ace II Android Development] Yønn:
Thanks a lot. I have two questions :

1. Does "hibernate" through Greenify apps is something like "bad closure" of an App ?

2. How can I identify receivers in DisableService ?
[Galaxy Ace II Android Development] ace2nutzer:
Just open Disableservices .. and choose OG-YouTube ... then disable everything for this app.

as for hibernate: it's not needed .. i've tested right now.. and when the video ended .. then wakelock works normally again.. even if the app is still open... so maybe it's really due to the receivers.
[Galaxy Ace II Android Development] Yønn:
Just to be sure, disabling in DisableServices means to uncheck the box, right?
[Galaxy Ace II Android Development] ace2nutzer:
yes, for OG-YouTube.
[Galaxy Ace II Android Development] giginski:
pls just tell me can I try your rom with chrono kernel? won't be any problems, i wanna compare battery drain, but right now your kernel drain much faster but is faster with this rom and smoother.
[Galaxy Ace II Android Development] shaqman89:
As long as it's kit Kat,its supposed to work.
[Galaxy Ace II Android Development] ace2nutzer:
Yes u can ... but later if u want to go back to this kernel here, then just delete all init.d scripts.

also u've to delete NT-APP or better just freeze it, when u want to use Chrono Kernel.

And later u need to unfreeze NT-APP if u want to go back to ace2nutzer kernel ;)

btw: at the moment the battery drain is approx + 30% because of overclocked LCD Freq for WS2401 Users ... (50 @ 80Mhz) .. but S6D Users are not affected ...

So in next build, WS2401 will have lower LCD freq, in order to save power. ;)

For expert user:

U can use video.modes like actually in my sources (gitHub) + Stock LCD Freq of 50Mhz ...

that all with an init.d script .. will work. (no need to rebuild the kernel)

For normal users:

pls don't ask how to do this.. i don't have time actually... i'm really busy with fixing bugs... those bugs exists on every custom rom... like cwm, lockscreen blackscreen (fixed) and right now i'm working to fix Offline-Charger Blackscreen for s6d users ... (already fixed.... thanks [MENTION=4365971]manthes[/MENTION] for testing ! )
[Galaxy Ace II Android Development] Yønn:
I have a little issue with BLN. I disabled it. But when my phone is charging and getting fully charged, BLN get activated.

This is annoying when sleeping.

Is this a bug or is there a way to disable this behavior ?
[Galaxy Ace II Android Development] ace2nutzer:
This is a feature :o

It goes auto. off when u'll unplug the charger .. or when turning the screen ON (if usual BLN is activted) or just after turning the screen OFF bln will auto. disabled. Actually there is no way to disable it. if it's disturbing for u, then put the phone of the display side instead of battery side .. then it shouldn't hurt ;)

Just now i noticed a strange problem when i am trying to open an image from google search in browser. Please try it by yourself too. Open the browser (stock) search for anything in google and then change the search from web to images, normally you'll see the images in thumbnails list try to open any image and , at least in my case, the screen fill with corrupt graphics. If you;ll close the javascript under settings everything work ok. I;m using the ace2 cm11 and his latest kernel with cm1 patch.
[Galaxy Ace II Android Development] Sylvinette:
Try using Chrome browser.
[Galaxy Ace II Android Development] Dr360r:
This also happens to me.
[Galaxy Ace II Android Development] bebolint98:
I also have this problem with ace2nutzer cm11 with chrono kernel.
[Galaxy Ace II Android Development] ace2nutzer:
yeah it's ROM problem .. not kernel .. it'll be fixed in next CM11 build ;)

I'll try it :D

Thank you ace
[Galaxy Ace II Android Development] miryn:
Did you change something for touchscreen freezes like Chrono did in his latest build? Touchscreen freezes is present also on your kernel.
[Galaxy Ace II Android Development] Dr360r:
Flashed as we speak. Everything normal.
[Galaxy Ace II Android Development] PolishVodka:
https://github.com/ace2nutzer/Samsung_STE_Kernel/commit/56fe45d2a311dfc67a1d2c8987d4574b74f341a6

This really allow us to use minimum brightness of LCD as possible? Nice, because for me even on minimum, screen was too bright. But this must be defined on ROM framework_base too, because options in CM11 (by TC, its stock value from CM) give you possibility to change by display settings minimum as 10. Must be changed to 1 as I understand.
[Galaxy Ace II Android Development] ChronoMonochrome:
It has nothing to do with setting brightness lower than 10. It just reverts preventing parameter min_brightness being set higher than 10.

And that change that allows to set brightness lower than 10 was already implemented by zwliew https://github.com/ace2nutzer/Samsung_STE_Kernel/commit/76f104c6393808032b12241f7e820d7e12791ed9 .

[MENTION=5840412]ace2nutzer[/MENTION]

Once again thanks for you great work but in the latest kernel the scrolling in 2d games suffer from lag and tearing. Is there a chance in a future to include again in novathor the option for changing the lcd freq ? Is going to harm our lcds the higher freq ? Im owner of ws2401 screen.
[Galaxy Ace II Android Development] ace2nutzer:
it's almost same like in CK .. i just didn't merged the latest one or two commits... since it finally works perfectly here since a few days without any issue.... so i was really afraid to modify the code... i just thought: never touch a running system ! :D

But anyway... this is strange ... that it still freezes for u ... have u undervolted CPU/GPU in NT-APP ??

Try without UV .. also with no OC for CPU /GPU .... also u can try to OV (overvolt) CPU @ max.. ---> 50mV or so...

For GPU not needed.

@ Min Brightness...:

to be honest it never worked for me ... even in the past when it was in NT-APP ... that's why i removed it .... but maybe now works ???

I'll try to make some echos ... and if it works i'll implement it in NT-APP again :)

btw: maybe u're right and it also needs some changes in the ROM itself ... actually i've see that we can change the min. brightness also in build.prop ... just set it @ 1.. and lets see if it works or not ;)

ro.lcd_min_brightness=1

First of all, u can't harm the LCD by simply changing a freq .... but of course the temp of the Chip will be a bit higher with OC .... but this is not much ... max- + 5° nothing more. ... But the Reason why i've revert it for now @ 50Mhz is because @ 80Mhz was draining too much battery .. the differnce is approx 30% .. no matter if IDLE or LOAD ... this is pretty much. Also i'm pretty sure that it'S possible to make it working really good , so more better and smoother that 80Mhz ... even with lower LCD Freq .... so let say 50 .. or approx 60 - 70 Mhz .. by adapting the Video.modes Values .... And this is the Point .... and the most difficult part: every freq needs his own adapted video.modes ... ! to make it smooth + tearless ... the Video Modes are 6 Values ... and every of this Value u can choose an Value between 1 - 80

So if somebody is good in math calculations u can calculate how many DIFFERENT LCD Configurations are possible .... and this with additionally 4 different LCD Freq ----> 50 - 80Mhz ... !!!

Also 80Mhz is probably not the max. possible ..... i believe WS2401 can even handle 100Mhz ... but this is very painful .. and also it'll not work stable on every WS2401 .... And after that all... at the end it should work stable for every WS2401 + it shouldn't cause any Coloured tears ant the bottom of the screen .. ! As u can see, this is an pretty high complicated thing... but possible ;)

Just a little detail, while flashing Novathor Settings 1.6.3, in the prompt it says: "NovaThor Settings v1.6.1 for ace2nutzer Kernel Requires Kernel Version 20150810 or later" To avoid confunsions, you should update this in the next update ;)

[Galaxy Ace II Android Development] snyfear:
Hi,

Thanks for the massive update ace2nutzer. I've just installed it and everything seems fine.

Just have two questions :

* What are the most up to date recommendations regarding GPU tweaks? The ones from your third post or the default displayed in Novathor Apps?

* Is somebody heart about a flashable fix regarding the recent stagefright v2.0 security issue has google announced a fix on Nexus : http://xdaforums.com/nexus-6/general/stagefright-2-0-t3215502

Thanks in advance,
