312mhz boot now fixed
lionheart, interactive govs built in (disregard metaphase gov its a fail)
can run flashplayer on our phone
only 1 bug 312mhz cant go down to 156 and vice versa must be on 624 or 832 for it to ramp down to 156 (fix coming soon)

known bugs
1.INCOMPATIBLE with JELLYBLASTv3
wont boot and logcat show no such file or diretory /system/xbin/busybox(but i checked it busybox is there)
2.HYPERION ROM-reportd by vanhalen35
battery charging wont reach 100% when using setcpu stucks at 99% but unistalling setcpu and rebooting it charges up to 100% dont know why but on my ussrv6 it charges just fine up to 100%
3.#39rev1
468mhz isnt working properly yet
4.#48
kernel version shows up as unavaiable under settings>about phone>kernel info .but is seen using cpuspy
startup is laggy due to it boots up using 312mhz
5.#50
CPU states cannot be read except for deepsleep
still laggy at booting but after a while it is fine
728 is not stable, the rest seems fine need verification from you guys
6. #51
still havent solved the cpu booting at 312mhz
7. #53
312mhz cant go down to 156 and vice versa must be on 624 or 832 for it to ramp down to 156 (fix coming soon)
just report anyother bugs you encounter
big big thanks to these guys:good::good::good:without them i woulld not even know how to compile a kernel without their help

[tips and tricks] performance and battery life for android kitkat 4.4.2

As we know we have android kitkat which is one of the best os version for our phone.
by following twicks and trick this we can make it more fluent and responsive i think it will be more helpfull those facing perormance and battery problem
1) ART (ANDROID RUN TIME):
THIS IS ONE OF THE MOST EFFECTIVE WAY TO boost u r phone performance
for me my quadrant score is 3500 with art
>no lag(0 lag)
>faster opening of apps
>more touch response
drawbacks :
>as we change runtime to dalvik to art some apps may crash or may not work specifically Google gapps
solution :
there not complete solution but i go this way all is well till now
art compatible gapps http://d-h.st/hSL
art compatible android app list
http://www.androidruntime.com/list
note: art is not compatible to xposed framework so u have to uninstall xposed
2) unistall xposed :
when you go for customization u prefer xposed framework i had done same thing but when I unistalled all xposed apps and framework phone was super smooth
3) use greenify
this is root app which hibernate all installed apps except system apps so when there is no use of app it gets hibernated so no baground runup of apps so no ram compsution and no battery drain
u will get it on playstore
4) debolting of rom:
debolting of rom will space freeup all u r system and make it faster
remove only application that are safe to remove list is as below
http://forums.androidcentral.com/op...e-apks-their-purpose-safe-not-remove-big.html
to remove app just go to any root browser >system >apps and priv-app folder>delete unnecessary app
5) overclock u r Rom with battery efficient kernel:
As our great developer made cpu gpu oc/uv kernels we can use them for overclocking of rom which definaltely boost performance
this is oc kernel for resurrection remix 4.4 rom kernel but it may work on all roms as i personally used it for cm11 maclaw, beanstalk 4.4 roms except aicp rom by vikasayu where i got boot loop
http://www.androidfilehost.com/?fid=23329332407591111( thanx t4n017)
this kernel great so far in terms of performance and battery life
remember oc is not working on all phone
to tweak cpu speed u can use these apps
> nofrills cpu control ( play store)
> set cpu(play store)
go to app and set max cpu 1250 and min 200
or as per u r wish where u got performance
to tweak gpu u can use this app just flash it via cwm recovary
>novathor settings app
http://www.androidfilehost.com/?fid=23329332407587599 ( thanx t4n017)
go to gpu > set mali low load clockspeed and high load speed to max l.e 680 mhz
so u r gpu will work at full speed
or disable auto boost and set static frequency to 680 mz
Note: more than 680 mhz may cause freezing lagging and screen tearing
6) system tweaks
in cynogenmod there are number of tweaks
1) go to system >performance >enable purging of assets
2)go to system >performance >enable kernel same page merging
3) go to system >development >enable 2d drawing
7) AVOID:
1) don't use any ram booster app
2) don't use any system cleaner
3) don't use any app killer
because u r kitkat don't need this any more
BATTERY TWEAKS:
battery is major problem of cynogenmod 11 (kitkat) it's default thing because these roms are meant for performance so its affect battery than stock roms
but we can reduce heavy battery drainage nd u r phone will withstand 18-20hr
1) odex u r rom
as all stock rom are odexed so they gives performance battery life with less customization
but u can odex ur deodexed cm 11 rom by this script
http://forum.xda-developers.com/showthread.php?t=2527268
download script
go to recocery
install it
reboot phone
go to terminal eluminator
type su>enter>type odex sysapp(odex system app) or frame (odex framework) or all (odex both)
2) use greenify
3) change u r runtime to art
4)debolt u rom
5) go to system>performance >set processor abyssplug max freq:800 min freq: 200 and io schelduler to sio
i personally uses oc kernek with max 1150 min 200/ ondemand/ sioplus but i undervolted the rom
6) undervolt u r rom:
if u r using oc/uv kernel then by using novathorseetinga app u can undervolt kernel and save u r battery
go to novathor settings app > go to cpu> go to cpu voltages and set cpu undervolt as per wish but i personally uses
-25 mv
note: very high undervolting or overvolting may reboots u r phone
7) deep sleep state:
deep sleep state of phone is that when u r phone is in standby mode u.e u r not using it screen is off it goes to sleep but some process are working which cause battery drain u can change that setting
>go to novathor setting app > go to power> set deep sleep to 4
OR
USE galaxy s advance setting app> go to deep sleep stateand set it at 4
at 4 u r phone goes to high deep sleep state so no more battery drain in sleep
note: dont go for deep sleep state 5 phone may be unresponsive u have to reboot it
8) screen filter:
>this is a app on play store which deems brightness of screen backlight which helps us to protects our eyes and again on amoled screen reduces battery drain too
> personally used and voila very effective
> u can easily control filter in status bar as it has stausbar notificaton when u are outdoor just increse its percentage and when u are indoore just reduceit manually as per u r wish where u got best result
>download it at play store
once again if u have more suggestions then plz mention here so we have best set up our beloved sgs advance for
performance and battery life

i am too glad that u liked this thnx bro.

Super cool tips bro!
I hope the app killers, cache cleaners and ram booster apps will become obsolete with KitKat!:good:

App killers, cache cleaners and ram boosters have been obsolete since at least froyo where android "learned" how to take care for itself. It's only got better since then.

nice bro.. good tips n solved my battery problems.

Uninstall all xposed apps and use greenify? Im confused...

@ortek donation version of greenify is related to xposed framework to hibernate system apps but there is no need to hibernate system apps because some process must be runed by Android os as they are necessary
so don't be confuse i have mentioned here about oridinary version of greenify

So if i want to use greenify i shouldnt install xposed?

Can i install this kernel on RR rom?
If not, Can you suggest me which kernel would be better for RR?
Thanks in Advance

@Ragwan yes it will work with rr rom( kitkat version only)
But keep nandroid backup if any thing goes wrong
I think given kernel link it's kernel of letest pa 4.4 rom its built with gcc 4.7 any fast and smooth no lag anymore.
Again if u want to try then use boot img of liquid smooth 3.2 its gcc 4.9 sabermod fast and smooth but i felt some reboots works great with Abysplug governor

In op you say about "CPU undervolt, bit in novathor setting i can undervolt only gpu....
So, CPU or GPU undervolting?

[Q] How do i fix game lag issue in my rooted GT i8262 ?

yesterday i downloaded this game 'FRONTLINE COMMANDO 2' (size ~ 80 MB) on my phone but i am having problems running it. its not even HD with big file size , just 80 MB but its not running smoothly. it lags all the time.
my device - samsung galaxy core GT i8262 *rooted* (4.1.2)
is there any way (app/mod?) i can fix this ?

Try overclocking your phone or install seeder.

First of all play game in low graphic mode (if it have a option like that)
Use Greenify app to hibernate apps that keeps working in background and eating your ram
Install seeder and set it to extreme mode
Overclock your Phone using any cpu manager app
#You can also uninstall some bloatware apps using root uninstaller.
Hit thanks..

i am using greenify and have already removed most of the bloatwares .
i wasn't aware about overclocking so i Googled and found that i need to have custom kernel to overclock the cpu.
i have stock ROM and kernel so i dont know if can do it .
(would appreciate if anyone can paste a link of guide on overclocking in galaxy core devices)
i m going to try seeder for now ... will post the result later.
thanks for the reply mate !

you can overclock your cpu using some apps..
that won't give the perfect results to you (bcoz of not having a custom kernel) but will increase processing power a bit..
It will heat up your phone too
give it a try..

No app will overclock the CPU if the kernel does not support overclocking. Do not talk if you don't know what you are talking about.

Exactly, stock ROMs never ever support overclocking. And there is still no custom rom/kernel for galaxy core that can do so.

i tried an app from play store which is used to overclock cpu.. [this app: https://play.google.com/store/apps/details?id=com.danez.cpusaver ]
it didn't worked for me that well but it increase the power of my cpu a bit.. thats what i also told him in my above reply.
The change was not shown in app but while using that app i can see the difference in my phone. I tried playing asphalt 8 in my core but it lags so much but when i started using cpu manager app the game stopped lagging. Thats why i told him to try that app & i know all about the things that i am talking about

I think you just set your CPU frequency to a constant 1.2GHz.. or just changed the governor to performace.

Yes I set the frequency to a constant 1.2GHz and that increased my core's performance a *little_bit

So, at first i tried 'RAM Manager Pro' in 'Hard Gaming' mode and it did work but to a little extent.
then i tried 'Seeder 2.0' and it was much better. Though the game still lags a bit but its playable now and it has option to
enable/disable it whenever i want to play the game. I will continue using seeder for now.
Thanks everyone for your help! :highfive:

Does this fix work for stock MIUI 6 kernel??

Awesome! I can't believe no one comments on this. This fixed my issue with miui7(completely stock btw) that for some reason didn't use lower frequencies than 960mhz. Just used no frills cpu control and was able to fix the lower frequency at 200mhz and changed governor! Checked with cpu spy and saw its now using the lower frequencies. Thanks a lot

@Kiran Anto does your RazorReborn kernel also need this patch? or were you able to incorporate this into it? Btw thanks for the good work!!

How can i undo this? the setting messing up with my phone.. works the opposite~

Can someone explain the reason for a117 Kitkat kernel's battery drain problem issue?

Again, I am giving answer to my question The kitkat kernel battery drain issue is because of akm8963 driver (magnetic field) which prevent system to suspend. I can solve the deep sleep problem but can not find the source code of kitkat kernel. So I wrote a init.d script and a program to solve this issue indirectly. By this script and program, I got %1 per hour battery time (3g/wifi closed) while screen off.

Really gud.
1% is not to bad. Atleast someone has tried for it. Pls help some Dev to solve KitKat kernel issue for our canvas Magnus.

I modified a rom (Lite-kat) for Piranha Zen (clone of a117) with this script and program. We can use a117 roms with piranha zen, vice versa should work also, you can try. A small modification must be done to script code, max cpu freq. value for piranha zen and a117 are different. İf you send the min and max freq. values of your cpu, I can change the script.
You can find the rom here.

max frequency is 1500 n min frequency is 497.

Yes, something like them, but I need the exact numbers, you can find them (if you are rooted) on "/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies" file. The first number is max freq, the last one is the min freq. I think our min values are same: 497250. if you send the max value, I can change it.

max frequency is 1508000
n min frequency is 497250

As I said 1% per hour screen off, and with continuous video play I got 6:30 screen time (cpu is mostly 497 while playing). I didn't try heavy cpu load like games. if you try, share with us. Is rom working with a117?

Can u gaive us the script and program so it can be used for other kitkat roms also.
Thnx!

The script and the program are inside the rom that i gave the link for. But it is not stable with all roms, i am uploading the stable roms. And developing the program in order to be stable with all roms.
Do you have chance to try the Lite-kat rom, is it working on a117?

I will try it n tell u tommarow. ASAP

ROM is working fine in a117 n as u said almost 1% battery drop in an hour when in sleep but we want this mode to work in all KitKat ROMs.

1% drop with 3g data on and dual sim? Battery drop is there like stock rom or any other rom when it suddenly drops to 15 or 20%?

md6 it may help
