Dude ... when did u finally STOP to write BULLSH!T in every thread :confused:

1. i haven't found that good Values "5" .. i've just suggested to Chrono to use in her Kernel also "5" instead of "10" in order to fix blackscreen. ;)

2. The first person who found that optimization for fixing BS Bug was [MENTION=3300472]jereksel[/MENTION] if i remember me correctly ! :cowboy:

3. i did a commit 28 days ago for hardcoded "5" Value.... see here:

https://github.com/ace2nutzer/Samsung_STE_Kernel/commit/70fd34e092a231260740d82b4b8243a275d3b660

init.d script is just to set LCD Freq @ 57Mhz instead of Stock Freq 50Mhz ... that's all my friend ! keep ----> :cool: :highfive:

hi [MENTION=235339]chrono[/MENTION]

im trying R2.22.2 it great and i love it but lcdclk in 4.1.2 still bug if set default (60HZ) or maybe [MENTION=235339]chrono[/MENTION] have a solution for my problem

thanks :D
[Galaxy Ace II Android Development] ChronoMonochrome:
Do you use any additional scripts? Post here output of /sys/kernel/liveopp/arm_summary and /sys/kernel/liveopp/prcmu_qos_performance.

Actually only stock has this problem. For now I don't wanna waste time on this, but maybe later I will make new build esp. for stock.
[Galaxy Ace II Android Development] ChronoMonochrome:
Nothing unusual here. About changing governor - that probably means that CM11 performance profiles are enabled. If it's already disabled, then remove all lines from /ramdisk/init.u8500.rc starting from "#CM Performance Profiles". I mean following lines:

[Galaxy Ace II Android Development] ChronoMonochrome:
By a chance I returned for a time to stock. Yesterday I investigate the cause of the bug with screen messing on album orientation in gallery (I never had it on any CM, but for some reason stock was more affected to this bug). It seems to be solved now by downgrading LiveOPP to 2.1. Furthermore, it can handle even more undervoltage, in my case before 200 MHz was able to handle vbbx=0x11, varm=0xf, and now: vbbx=0x11, varm=0xc.

Changelog:
[Galaxy Ace II Android Development] heldix:
Spending his time for the community even at easter :) Thank you very much for ur work. My phone never behaved that fine until i started using ur kernel!

To the undervolting: Do u have pure numbers too? I think most ppl use the chrono kernel app and there are like for example -37.5mV values.
[Galaxy Ace II Android Development] ChronoMonochrome:
I'm too far from home anyway, and here do not celebrate Easter (at least, not as much as is customary) :)

Well, what can I say, usual uV presets may require more higher power consumtion to not try to decrease it. I've started to search for optimal vbbx/varm voltage as for sake of the interest, too. :)
[Galaxy Ace II Android Development] ayas02:
indeed before it is replaced to use version 2.1 liveopp how?
[Galaxy Ace II Android Development] ChronoMonochrome:
Besides of some new commands which are usually not needed to use(setting ARM_OPP, for instance), nothing else has changed.
[Galaxy Ace II Android Development] ayas02:
but screen blink was really fix when in set default ? :D
[Galaxy Ace II Android Development] ChronoMonochrome:
I never encountered it so far, even on stock. I assume, it's device-dependent.
[Galaxy Ace II Android Development] fluffi444:
Just to be sure what you mean:

- Update to R2.22.4

- Backup DATA onto SDCARD

- Format DATA partition

- Recover DATA again

Is this correct?
[Galaxy Ace II Android Development] nikolas1274:
But I swap memories, which one do I have too format, internal or external?

Thanks
[Galaxy Ace II Android Development] fluffi444:
That was the reason of my question actually. Iam not 100% sure what to format. Is it the DATA partition or is it the data of (one of the) sdcards. And if it's the sdcard which exactly?

But let's wait for an answer of [MENTION=5695278]ChronoMonochrome[/MENTION].
[Galaxy Ace II Android Development] ace2nutzer:
I'm not 100% sure, but it's meaning fuse_fs wich is sdcards .. Usually where app data is stored on sdcard if somebody has moved apps on sd cards
[Galaxy Ace II Android Development] ChronoMonochrome:
If have too many data youn need to backup, for example if you've swapped storages, you can try to don't format it. Try to check it for possible errors from Windows instead.
[Galaxy Ace II Android Development] fluffi444:
Ok. So it's the external sdcard. And we need to check it for any data corruption (app data location) may caused by former fuse_fs settings.

Thanks for clarification.

Don't know why I was focused on DATA partition...
[Galaxy Ace II Android Development] shaqman89:
So, just summing up, all we need to do is check for sdcard (/storage/sdcard0), and then we're all good to go, right?

Is it normal if I experience a bit lag after I do that, or would that indicate I need to do a full format?

Previously I tried without formatting or checking errors and I got random reboots after 5-10 minutes.

Yes, I am swapping my internal with external.
[Galaxy Ace II Android Development] monstro78:
Hey chrono

I think latest kernels 2.22.x have a little lag.... Personally 2.20 beta was very good... And also 2.17.x series was the fastest so far...
[Galaxy Ace II Android Development] riyosakura:
IMO 2.19.4 is the best so far. Experience so little lag with heavy usage.

Maybe, that is the reason why this thread title r2.19.4 and considered build after that as a beta.
[Galaxy Ace II Android Development] ip3000:
What's the difference between 2.19.4 and 2.19.4 pl031-stock?
[Galaxy Ace II Android Development] shoxieJESUS:

Reverted clock freeze fix. On stock coz of this fix clock are stoped
[Galaxy Ace II Android Development] ip3000:

Any changelog for r2.22.5?

Edit. No need anymore. I saw it on FTP.
[Galaxy Ace II Android Development] heldix:
R2.22.5

· Switched back to LiveOPP 2.2

· Some kernel optimizations [mkaluza]

· Fixes to binder driver

Im using it now and its working like a charm for me :)

Cleared all init.d scripts and deinstalled chronokernel app before.
[Galaxy Ace II Android Development] nikolas1274:
Do you mean that we have to delete chronokernel app? And what about swap?
[Galaxy Ace II Android Development] shaqman89:
I don't think it is necessary. I tried it too without any changes, and it is better than 22.4, but I still find that 22.2 in general is better for multitasking.
[Galaxy Ace II Android Development] matthias1976:
some problems with apps

dont really know from since i got these problems !? maybe only me !?

let me explain:

"whatsapp" and "threema" -> i often only get messages when i open the app. or hours later !!

google "my tracks" -> seems that app loss GPS, track not record complete, after maybe 20 minutes lost gps, track record not continue, time runs further in app but GPS iss lost. but it never loss GPS Signal -> controlled it by other app !?

"BaotBrowser" -> i open some tabs with some websites. when i press homebutton it stays in memory. normally when i reopen app the tabs still present, now after some minutes tabs forgotten.

maybe apps or processes got killed by too agressive momory settings !? <- my thoughts about !!

am i the only one with these problems !?

my config: mostly latest kernel, chrono settigs app, poppmensa CM11, Dynamic 200-1200 mHz, no Uv
[Galaxy Ace II Android Development] heldix:
I for myself dont have those problems. Everything working great. I used navigation with google maps and osmand (bicycle navigation) for hours.
[Galaxy Ace II Android Development] ChronoMonochrome:
Actually, many changes after 2.19.4 are still under testing.

Can I ask, how did you come to this conclusion? I need to ask, cause I usually don't run many apps and didn't notice any difference between mentioned builds so far.

Could you disable UKSM and check whether it's better or not?

echo 0 > /sys/kernel/mm/uksm/run

Also make sure that swappiness at least is below 50 if you use ZRAM.
[Galaxy Ace II Android Development] shaqman89:
I came to the conclusion after trying it out for more than an hour. Usually by this time I have already opened around 6-8 application (usually bbm, whatsapp, facebook, Instagram, Tapatalk, browser, messaging and contact. In addition, I am using lmt and SwiftKey) and constantly cycle between them.

When I am on 22.2 (currently on it), there are no real lag when switching between apps, but on 22.4 I have to really wait just to open the keyboard or switching an app or even change a menu. On 22.5, it is better when opening the keyboard, but switching between apps is still a pain.
[Galaxy Ace II Android Development] xo.en:
22.5 seems to be fastest one so far, 15200 antutu at 1150mhz cpu, 580mhz gpu is quite nice result(even if i am using no oc for daily usage). Every single test shows better result than before with same settings.

Zero blackscreens, no sound loss, everything seems to work perfect so far.

For me most important thing is 2d performance, which is great here.

upd: after small tweaking here and there - 1150mhz cpu, 580mhz gpu - 15314 antutu, fantastic each test results.

Downside - i am not able to reach 1200 mhz for cpu. I had stable 1.2ghz with earliest oc kernels...

btw, dynamic gov is really slow(and i had blackscreens with s6d), ondemandplus seems to be optimal.
[Galaxy Ace II Android Development] ChronoMonochrome:
So, what build is latest stable for you(latest one without any modifications to LiveOPP - < R2.22, or something else)? I had some doubts about my modifications to LiveOPP 2.1, therefore I reverted it to LiveOPP 2.2.
[Galaxy Ace II Android Development] xo.en:
With my set of tweaks(lmk, vm, etc) each one is stable with ondemandplus/fiops(nice cpu usage for my way).

My woes were related to dynamic gov, mainly(blackscreens, weird delays, etc).

Latest kernel seems to be fastest one, imho.

Actually I am trying to make 600-700/200 setup. 700 mhz is still faster, than old 800 mhz, so..

BUT there's the point: proper lmk/vm, LOW swappiness, NO zram(kernel's init.d script removed), KSM enabled(although i think that ksm may be related to occasional gui lag).

I am impressed so far.

My only concern is about battery - latest kernel sucks more energy, although i am not sure about that, yet.

btw.. my table of voltages(800/200 setup, old one):

100mhz -50

200mhz -50

400mhz -50

600mhz -50

700mhz -50

800mhz -37.5

Definitely unoptimized, i know(for 800mhz, oldest oc/uv kernels were stable with - 50 for cpu, now, i am not sure).

Ape 25/25, 60 s6d, no flicker. fiops for int/ext. Machine manually reparted.

Stable. Yup, i could push it moarrr...probably.

<Mod Edit>
[Galaxy Ace II Android Development] Alex_Gamer:
Anyone can tell me why antutu its closes itself at the end of the graphics test? :(
[Galaxy Ace II Android Development] acrocosm:
OK I'm unable to mount

anything

under twrp. Actually I have never been with this kernel. Is there a way to flash newer version other than download mode?
[Galaxy Ace II Android Development] heldix:
Its kinda wierd that ppl have such different experiences with kernel versions...

I have 2.22.5 running on two Ace 2:

- All init.d scripts removed

- Chronokernelapp deinstalled (for he doesnt autoload settings into the fresh installed kernel like CPU Settings etc., ZRAM Settings, IO Settings etc)

- 2.22.5 installed via twrp

- No other changes/tweaks not even io or uv

On both phones i got the BEST battery life ever within the last 3 years. At days end im still around 50%. In my humble opinion not deinstalling chronokernelapp before upgrading the kernel might overwrite some kernel settings thru autoload of the app at boot.

Even with heavy usage of bigger apps (clash of clans, quizup, maps, osmand, chrome) and switching between them i get really low loading times. That's a point where Chronos kernel beats Ace2Nutzers one by a lot imho. Ace2Nutzer always worked very smooth for me up to a point where u get that 20 seconds lag after a lot of multitasking/switching.
[Galaxy Ace II Android Development] ChronoMonochrome:
My previous question was mostly about 1200 MHz frequency. What's latest build that was stable with it?

I've already answered some months ago. There's no point to work on one project. This is not that case when proverb "two heads are better than one" works. It's not only about me or ace, I never have seen that two kernelsmithes worked on one kernel, at least when they already worked on their own kernels. The reason is simple. Each of developers has its own vision, about how various things works. That's why better to work separately in this case.
[Galaxy Ace II Android Development] xo.en:
VERY first OC kernel was stable with 1.2ghz. I really do not remember which one was that(some 4.3.x line). If roxsel's one had OC, that would be it.

Yup. That was my point, although i could say it more politely..
[Galaxy Ace II Android Development] perfect_:
Big Thanks for this great kernel. :o
[Galaxy Ace II Android Development] ChronoMonochrome:
Uploaded R2.22.6. This fix belongs to CM12.x, where's appeared problem with installing apps due to dex2oat failure cause of disabled highmem. With enabled highmem we have a bit slower kernel, but it's only way for me to support lollipop too. If you don't use CM12.x, there's no need to update.

UPD. although CM12.1 anyway doesn't boot with it, will look into this some later.

UPD2. version for CM12.1

Also, with -Ofast optimization. Thanks to PolishVodka for ramdisk, that I took from his build.

HIGHMEM turned out to be unneeded on CM12.1, although there's a bigger evil, that's so far unavoidable - selinux. For cm12 use usual version 2.22.6 (without selinux prefix).
[Galaxy Ace II Android Development] shaqman89:
This actually helped. Now I'm on 22.5 and it is better than my previous trial.
[Galaxy Ace II Android Development] ayas02:
so R2.22.5 isnt better than R2.22.4 ?
[Galaxy Ace II Android Development] shaqman89:
In my experience, 22.5 is better than 22.4.
[Galaxy Ace II Android Development] S.AMU:
Somewhere in this Thread I wrote that I had Problems with my GPS. It was hard to get a fix, had only about 5 sattelites and not more.

One guy wrote here that he has the same problem (I forgot your name, sorry)

Now today I had two options: :fingers-crossed:

1) flash stock and test GPS with this

2)dissassemble the phone and look inside, perhaps the antenna is broken or something else.

I decided to do number 2:

After opening I saw, that the antenna is connected to the mainboard via a ground and a signal pad. So I cleaned those two pads with electronic-cleaner and light air-pressure and reassembled the phone.

Now Im getting, on the same place outside where I got only 5 sattelites before, up to 21 with 4m accurancy and "green or yellow signal strenght bars" for each sattelite (befor it was always red or orange).

So GPS is fixed :D :D :D :D :D

really chrono ?
[Galaxy Ace II Android Development] ChronoMonochrome:
This works quite well for me. I use cm12.1 as main ROM + Slim Bean 4.2.2 as secondary (some additional stuff turned out to be needed, fstab and ramdisk for 4.2.2 - http://xda.mister-freeze.eu/XDA-files/ChronoMonochrome/DualBoot [WIP]/some stuff/4.2.2/ )

And please use quotations more reasonable.

[offtop]

P.S. actually I can't notice any diffrence in smoothness between CM12.1 and SlimBean. Now I'm asking myself for what purpose I still use CM12.1 :)

[/offtop]
[Galaxy Ace II Android Development] ayas02:
So [MENTION=235339]chrono[/MENTION] can i use stock JB for first ROM ? and how switch first rom and second rom ? thanks :D
[Galaxy Ace II Android Development] ChronoMonochrome:
I've already wrote that external sdcard should be reparted for installing second ROM. For some reason, I can't repart my external sdcard (all data should be backed up), that's why I haven't write step-by-step guide for this. You'd better wait until somebody test it, if somebody willing to.
[Galaxy Ace II Android Development] ace2nutzer:
@ up

it's great to make first backup before do the unpart.. but it should also work without clearing data first...

Use gparted .. first resize the partition and then create new part. on the new allocated space.

Don't wonder, it can take some minutes ... especially if the sdcard is very full ...

btw: Amazing Work !! - Now i'm really thinking about witch second rom i should use on the side from CM11 .. hmm.

What about Bugs on CM12 ??
[Galaxy Ace II Android Development] ChronoMonochrome:
Thanks for idea, but I anyway need to backup data first, cause of possible sudden power cut(the charger is nearly broken and the battery broke down some time ago), that may happen during this procedure.

It's still not very suitable for daily usage. Here's its topic... http://xdaforums.com/galaxy-ace/ace-2-general/cm12-alpha-t2989178/page6

Hi, i have a little problem with battery.

My battery drain a little bit faster for about 2 weeks

When i charge my battery to 100% at the morning(8am) then at 5pm only 10% battery remaining. Or it's normal?

I'm sure that my battery not broken yet :p

I just used my phone to "social media" or playing music(not really often)

I used dynamic gov and 200-1000 cpu feq

So what CPU gov should i use to resolve this problem? or there are another things to change?
