Hello. I flashed your kernel to Galaxy Ace 2 with CrystalPA 8.5 ROM. Everything's fine except my data connection. I cannot connect to data service anymore. I didn't change anything; everything's set up correctly: Access Point names, Data and Data roaming is enabled. Is it a bug?

CrystalPA Version: 8.50; Baseband version: I8160XXNB1, Kernel: ace2nutzer-g6304d77.
[Galaxy Ace II Android Development] fluffi444:
Even its not needed anymore - I like to have a 100% and easy solution - Therefore I took [MENTION=5840412]ace2nutzer[/MENTION] Idea (thanks for pointing me to this direction) and made and zip for easy install via CWM - maybe some of your are running into the same issue..

Just flash file via custom recovery - It will deactivate "Set on Boot" for CPU freq! You can activate it again via preformance menu after system booted completely
[Galaxy Ace II Android Development] ace2nutzer:
Have u formated /modemfs?? Can u check your baseband ?

Very nice script ! Of course that's more user friendly ... :D I'll upload this on my dev-host for just in case ... of course with proper credits to u. :)

Thanks!

I installed 20150207 this afternoon, and had quite some blackscreens. After a couple of tries, the screen eventually worked so I did not have to reboot the phone yet. My handset is s6d codnia with ext4 and dalvik. If there's anything else you need to know, just let me know! :)

Cheers, and thanks for the hard work mate! ;)
[Galaxy Ace II Android Development] ace2nutzer:
How often per day have u the blackscreen ?? And is the blackscreen also in cwm ???

I'll make new build !
[Galaxy Ace II Android Development] Matteo90:
I think I had around 4 today. No blackscreen in cwm so far, will check again tomorrow.
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!!

Changelog:

20150210:

Better Battery Lifetime

More Speed

Much more responsive

Fixed Bug in I/O - [ChronoMonoChrome]

Re-enabled printk --> dmesg

Avast Firewall is working again

Notes: Wipe cache in Settings -----> Storages (just tap on "cache" ---> ok ) and wipe cache in cwm ... wipe dalvik cache is not needed.
[Galaxy Ace II Android Development] ChronoMonochrome:
Could you write changelog more detailed? :) I even don't understand how exactly I helped with bug in I/O(what did you mean, btw?) Is it SPI CRC or something else? Ok, I've read github comment and now understand - this is disabled sched mc/smt powersaving tweaks. But this is not so obvious for other users.
[Galaxy Ace II Android Development] heldix:
I went back from the 0702 to the for me last non laggy version 30-01. The 0702 starts pretty well but gets more and more sluggishy over the day. I try to dial a number and have 10 seconds black screen before the dialing menu shows up.

Anyone else got this?
[Galaxy Ace II Android Development] BlueZ-:
For me is always ok, even after hour
[Galaxy Ace II Android Development] snatch_bill:
I am using 07022015 version ext4 and dalvik.

Everything working fine so far.

The only problem I've found is that flash videos

Don't play correctly in the browser.Only sound is heard.

When switching to fullscreen ,video plays fine.

Is there a solution to this?
[Galaxy Ace II Android Development] ace2nutzer:
It' s just disabled sched-mc-powersavings + sched-smt-powersavings + wq-power-efficient-default .. That caused slower system and sometimes audio drops during screen on and off ... Also less 1000 points in AnTutu. I Think u're right.. That sched-mc thing is buggy..

PS: the user can also take a look in my github... Only things what is not commented is when i change smtg in ramdisk. But i write here in Changelog.
[Galaxy Ace II Android Development] ace2nutzer:
Nope... It's just cm sources bug.. And why u guys are reporting bugs from the 0207 ? We have here the whole day the new build: 0210 :D

Btw: on latest build everything ok? Blackscreen, sd / app problem?
[Galaxy Ace II Android Development] Bito21:
So far no problems. :D
[Galaxy Ace II Android Development] primewell:
Running with 1,2 GHz no problems on 10/02 etx4 kernel. Ace 2 beats my new moto g LTE (stock kernel, quad-core Snapdragon 400/Cortex-A7, 1,2 GHz) in multitasking, runtime and float operations on Antutu (left Ace 2, right moto g LTE)... this is crazy, why did I buy a new phone :D :eek:
[Galaxy Ace II Android Development] Alex_Gamer:
Sd card not woking on latest build :(
[Galaxy Ace II Android Development] soko3:
latest build stable as previous versions

1.1 ghz cpu/450 mhz gpu

quadrant: 3200... 100 points more than previous version :D

Btw, is there any way to disable Google Analytics Service?

It's taking 12-13 mb of ram, but can't be disabled with "Disable Service" app....
[Galaxy Ace II Android Development] Alex_Gamer:
Sd card is working for you?
[Galaxy Ace II Android Development] soko3:
it worked always...
[Galaxy Ace II Android Development] Alex_Gamer:
For me not working
[Galaxy Ace II Android Development] ace2nutzer:
This is great !! Thanks for this great comparison ! :D But don't worry ... that's not all ;)

@ all

what about sdcard / missing Apps Bug ?? And what about Blackscreen in cwm or after waking up ???

Actually i've only one Report for non working sdcard .....

btw: @ alex gamer ... try again wipe cache and re-download the build again.. and flash it again.. maybe smtg goes wrong with downlaod etc ....
[Galaxy Ace II Android Development] Jaro89:
I don't have any apps on sd, so can't say if the're gone after flashing 10.02. But when i move apps to sd, they're not working anymore. Don't know if art has any impact on this (I'm using art). Anyway, everything is very smooth and fast. Great job.

I also have ace 2 and moto g lte. Those are my antutu's results:

ace 2

moto g lte

Ace 2 with ace2nutzer's & TC rom f2fs and ace2nutzer's 10.02 kernel f2fs.

Moto g lte with CM 12 nightly 2015.02.04, default CM's kernel (as others for CM 12 are currently buggy).

How to download on stock without NFC ? Because I can't find the link.
[Galaxy Ace II Android Development] ace2nutzer:
Amazing !!!!!!

This Kernel is only for 4.4.x Roms.. :)
[Galaxy Ace II Android Development] borkins:
When I bought my phone ( with stock GB ), the highest voltage with plugged charger was 4.405V ( for about 2 months ).

But after some months of use ( on JB ), the voltage drop to 4.368V. And after I recharge the battery to 100%,

and leave the phone ( deep sleep ) for about 10 min., and when turn the screen on - the battery indicator shows 96%.

Today the voltage of "fully" charged battery is in the range 4.330-4.340V ( the battery is 21 months years old ).

And the battery indicator showing 93-96% - 10-20 min after real EOC ( without using the phone ). I don't know is it a battery problem.

Before two months, I saw that the phone going off at 0% - 3.000V ( I watched some file with script ).

Then I was surprised that the phone holds 1% for at least 30 min.
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for this great Informations !

That what are u saying .. i can confirm nearly all. I can me remember on Stock GB and JB.. i had the best Battery life.... both same...

But i don't about charged voltage.. in the past I never check'ed this. ... But i believe the thing with 96% .. I've this since Stock JB... !

Even here on Stock TC.. and now on my kernel.. U / all need to know that Stock TC Kernel is not based on Stock CM Sources..(don't exists) but it's based on Stock JB ! I've downloaded the Stock JB Sources and compared it with Stock TC Kernel.. nearly everything is the same for abb-charger Driver .. the only thing: cocafe added abb-charger current control.. and Charging Cycle ... that's all ! Voltage Table are from Stock JB implemented... Perhaps Stock GB uses another Voltage Table.. i don't know because i don't have downloaded this Source.

Those Things with 96% and 4360mV etc.. are nearly nothing to to with the Battery.. it's all realted to Kernel.. / Charger Driver...

But of course, too old battery.. can't hold big Voltage.. it'll decrease faster.. even on IDLE without any load.

But even with half broken Battery the end voltage should be that Value what is programmed in the Charger Driver.

Even the Thing @ 1% .. I can change the table ... then you Phone will shutdown @ 15% .. no Problem.. or vice versa that the Phone can stay ON for 2 Hours @ 1% .. :)

About Shutdown Voltage.. i remember me.. we had some Builds from Rox with changed Shutdown Voltage.. from 3300 @ 3000.. but not really shure.

I'll upload new Build now.. there is nothing new.. only abb-charger fix -----> Build 20141101_p1
[Galaxy Ace II Android Development] Andrewbons:
I tried 2 days with this kernel

Everything works fine, it's good. BUT i can't understand why it drain battery so much :( with chrono kernel my batter last almost 2x more
[Galaxy Ace II Android Development] ace2nutzer:
nope... it's just wrong displayed percentage.. because of changes in Battery Voltages Table.....

But I've fixed this + improved Battery Life in latest Build here: 20141101_p1 .. But very Important: After install this kernel.. shutdown your Phone over CWM.. and then turn it on.. boot.. and charge the battery completely full to 100% ! Not 99% !

Then use the Phone till 1 % and take a look into battery stats org. from android ... and post it here :) :o
[Galaxy Ace II Android Development] Andrewbons:
I already did that. I've tried this kernel for 2 days, with 9-10 hours battery lifetime, while i have 24+ hours lifetime with chrono kernel :\

With chronokernel i have to use -75mv cpu undervolt, while with yours i can go -100 without any problem. Maybe it's something related on voltage.

Kernel wakelocks are OK, already checked with betterbatterystats ;)
[Galaxy Ace II Android Development] majid92:
thanks man for your good kernel :) i wish more success for you :)
[Galaxy Ace II Android Development] nikolas1274:
This one working for me too

Thanks

---------- Post added at 08:54 PM ---------- Previous post was at 08:48 PM ----------

Also I am using NT for the swap and in don't have problem, what suppose to be the problem with the NT?
[Galaxy Ace II Android Development] doctormord:
Ace2Nutzer,

Charge termination on li+ batteries is (standard) defined at 1/10th of capacity. Beside this, cycle life is better when not charged/discharged 100/0% but 80/20.

Using 1031 kernel charges really slow, seems like 350ma charge current..

Regards.
[Galaxy Ace II Android Development] RootPegasus:
[MENTION=5840412]ace2nutzer[/MENTION], i hope you will update this kernel for stock JB 4.1.2 :)
[Galaxy Ace II Android Development] MarquesYOLO:
A couple of days with your build and last kernel and it works great, but I don't feel better battery consumption, and settings/themes/wallpaper-lockscreen FC. I had this bug in many rox builds but in last [MENTION=5285056]poppmensa[/MENTION] build I flash, bug has gone. I don't know if you could solve it, anyway is not a big problem.
[Galaxy Ace II Android Development] LyrixTheDj:
issue with video stream

Use ace2nutzer rom 20141025 + kernel 20141101_p1. All work fine and smooth, but have issue with video streams.
[Galaxy Ace II Android Development] nikolas1274:
Any one manage to swap without NT? Because I use NT and I have some random reboots
[Galaxy Ace II Android Development] ace2nutzer:
Now u know why .. ;) Bacause Nt-APP set too low CPU / GPU Voltages.. and u can't fix this by OV. in the APP... because Voltage algorithm is also wrong.

Nope... but how can u see this ?? I need to know the percentage of battery.. from 100% - xx %

Thanks ! - I've already corrected this in my sources.. termination current now: 150mA 1.st. and 2nd... and max. Voltage 4340mV

instead of 4350mV .. but shows anyway 4350mV in apps... but with 4350 --> 4360mV ! Therefore i reduced it @ 4340mV..

4350mV is org. Charging Voltage.. u can see this Value on the Batt. and on org. Samsung Sources... So now i think everything is OK with charger :) Will be included all in next Kernel update !

I will upload Kernel versions for other Roms.. when i'll release some Final Versions.. then i've time for other Roms ...

Please be patient... or just update the ROM @ CM 11 .. really no reason for don't use CM 11 :)

Better battery life is definetely here.. and about FC.. i don't have that Bug.. perhaps do u freeze oder delete some system apps ?

Live Video Stream is not fully fixed... on 25/10.

@ all users:

can you guys post here your values from /d/prcmu/avs ?

It'll be very helpful. This may shed some light, why LiveOPP work unstable on some devices. Thanks in advance.

Just blank on my device, is it normal?

I open it with text viewer on xplore file manager.
[Galaxy Ace II Android Development] ace2nutzer:
Really strange ! Can u plz try this:

reboot and then open this file with Text editor.. but that incorporated by the stock FileManager.. thx
[Galaxy Ace II Android Development] borkins:
X-plore's text editor can't open it. I tried it to confirm.

Try with Root Explorer's text editor, also ES Note editor ( ES file explorer ), Solid Explorer's text editor.
[Galaxy Ace II Android Development] Alwer:
On clean install CM11, and newest kernel, memory swap do not work, I used novatorsettings app.
[Galaxy Ace II Android Development] ace2nutzer:
Strange... for me it works ... any other users with sdcard probs ???
[Galaxy Ace II Android Development] Alwer:
Ok sorry for wasting your time, I forgot format internal sdcard in cwm.
[Galaxy Ace II Android Development] ace2nutzer:
no problem ;)
[Galaxy Ace II Android Development] soko3:
what is your phone's cpu and gpu freq?

i wonder how to get 13500 points o.O

my phone with 1250 cpu/720 gpu get 12700 on antutu

does f2fs makes that difference???
[Galaxy Ace II Android Development] ace2nutzer:
@up

i think yes... f2fs + art is for more power + better battery lifetime...

i've f2fs + art and on second antutu run .. (the first test is not accurate due to ram ...) i've 13638 Points ....

And this with CPU 400/1150Mhz and GPU 400/690Mhz

My Plan is to reach ca. 15.000 Points in AntuTu .. then we can say "final" Version :o :D:D:D:D
[Galaxy Ace II Android Development] Jaro89:
Cpu 1200, gpu 675. F2fs is supposed to take care of trimming (kernel does not suport fstrim), and thats why i use it, besides - random write speed is increased (better performance in everyday use, not so much in benchmarks). My moto g lte also has system partition formatted in f2fs (by motorola) and it's fast as hell.
[Galaxy Ace II Android Development] manthes:
I tried your latest kernel just to see if it has cwm blackscreen but it still exists for me (s6d)
[Galaxy Ace II Android Development] ace2nutzer:
I'll building later new build... :)
[Galaxy Ace II Android Development] MrBlackCore:
I use f2fs + art + latest kernel + rebooted phone + airplane mode and i still get 12500/700. with antutu. Guess my phone is getting really old :D Still works better then ever with ace2nutzer`s rom and kernel. I can play very heavy games without any lag whatsoever.
[Galaxy Ace II Android Development] ace2nutzer:
The 13500 Points is meant by OC'ed Phone ... CPU @ 1150Mhz and GPU over script / init.d script @ 690MHz ... :)
[Galaxy Ace II Android Development] arroyo:
Debloat CM11 rom to about 50-60 apps (can be easily done without loosing any crucial function) or use SLIM ROM as a base and then debloat it to 50 crucial apps only. Do not install Gapps. Overclock phone to the limit. Put UHS SD card instead Class 10. F2FS + ART

... and you will get up to +500 Antutu points more.

Since latest kernels I can run 1200Mhz for 24/h it is time to push this baby beyond 14k Antutu points. Need to crop CM11 from 20141118 F2FS a bit.
[Galaxy Ace II Android Development] ace2nutzer:
Ok Guys... for all u with Blackscreen Bug on s6d LCD Driver ... Blackscreen (BS) after wake up or in cwm ... i'll make now everytime when i receive a bug report about BS a new BS Build ... this "BS" Builds is always based on actually Kernel Sources from me ... and additionally some small changes in MCDE Driver for tryng to fix that annoying bug for u Guys !

Unfortunately (or not) i don't have s6d Driver so that i can't fix with my Phone .. that means i need your help / support / reports.

An other alternative is: if anyone with BS Bug is living here not far from me .. (wohle Germany :D) so u can also send me the ace2 with s6d Problem.. and i'll try to fix that.... for more informations pls send me an pm. Thanks.

Dunno why but your 2 latest build give me random reboot at 1200,n this is not happen with your old build (say 3001 build) i can running 1200 smoothly,i use ext 4 ,your rom n latest kernel n not touch anything
[Galaxy Ace II Android Development] Alex_Gamer:
Hey [MENTION=5840412]ace2nutzer[/MENTION] i start again from scratch(3 file ROM, oficcial jelly bean and cm11 with latest kernel realease) now everything is working but i have one bug, later I'll gonna take a screenshot with the problem.

On 0210 I had a reboot when watching a video in chrome. CPU@1ghz and GPU@600 if I remember correctly. Here's last_kmsg.

As for blackscreen, I don't remember having any, but sometimes it takes 1-2 seconds for the screen to wake up. S6d.

[Galaxy Ace II Android Development] heldix:
I'm always a bit too late :) The 15-02-10 build is working great performancewise. No slowdowns after 30h+ usage. But today morning he had lost carrier signal (germany) and i had to reboot the phone.

Ill try the 02-12 one now.

Greetings
[Galaxy Ace II Android Development] jariasp:
I've always suffered this issue since I am on TeamCanjica CM11 with ace2nutzer kernels. My ACE2 looses eventually carrier signal, and I have to reboot the phone to work again normally ()3/4 times a day). Maybe it's something with the power save mechanisms ace2nutzer has introduced with his kernels... It's an annoying issue.
[Galaxy Ace II Android Development] MrBlackCore:
Everything works great for now /12 f2fs with art and 1200 cpu. Gonna report if I see simething wrong
[Galaxy Ace II Android Development] psidco:
0212,no random reboot so far ,i can move app to sd,but still get delay on waking up device 1-3 second(s26d) is that normal?

Edit:im use dalvik ,ext 4 and get 10770 in antutu with 1200MHz and 690 gpu :(
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for report Guys ! - But if u like to help me to found the issue, then it would be very nice if u can say me from wich Build (date) the issue with signal beginns ! Otherwise it's nearly impossible... thanks !

That's very good @ no reboots. Yeah, that's not really normal.. have u "messenger" installed @ latest version ?? if yes, it's actually buggy and cause too much CPU Load... i've fixed this issue ATM by simply disabling most of Services from Messenger app .. u can do it with: Autorun Manager ...

(let only the first service enabled... notify.messages.notification ......)

Can u pls report if the issue with sdcard is solved on latest build here: 0212 ?? Thanks !
[Galaxy Ace II Android Development] psidco:
Uninstaled the mesengger and facebook mobile long time ago,thats make my phone freeze.and sadly my phone reboot ten minutes ago,i think my phone too old :confused:
[Galaxy Ace II Android Development] ace2nutzer:
Nope.. i've messenger, facebook, whatsapp, and hangouts installed.. and no problems so far.

Maybe u should do an wipe data .. clean install can help. :) Format also system in cwm and install the 18/11 CM 11 and use pico uni-gapps ;)
[Galaxy Ace II Android Development] MarquesYOLO:
You say that uni version gapps is better than normal version? I always use normal version of Pico gapps, but if you say so I change :) I'm thinking of doing a clean install to try with art.
[Galaxy Ace II Android Development] ace2nutzer:
if u like one time to do clean install with ART + F2FS, then uni-gapps is highly recommended because of small SYSTEM partition !

U also need to repartitioning ... u'll find in my dev-host an cwm repart.zip for that ... if u don't like to it manually over ADB ! :);)
[Galaxy Ace II Android Development] MarquesYOLO:
And how do I flash this repart.zip? After clean install? First rom, gapps, kernel and then the zip? The zip first of all? I think to try with repart method by Chrono but I discard because I didn't understand very well his process.
[Galaxy Ace II Android Development] ace2nutzer:
- cwm backup, also sdcard0 per PC

- repart.zip

- install f2fs kernel from me

- power off

- boot in cwm

- mounts and storages: enable f2fs - etx4 conversation

- format: system, data, cache as f2fs

- format sdcard0 as vfat

- install CM 11 from 18/11 for f2fs

- install pico uni-gapps

- install latest f2fs kernel

- reboot system

- restore or better copy the saved content from sdcard0 @ sdcard1 (because sdcard0 it now only 10MB ! )

- shutdown the phone

- boot in cwm

- backup and restore

- advanced restore from sdcard1

- restore ONLY data

- wipe cache

- reboot system

- swap storages in NT-APP

- ENJOY !!
