hi guys, i'm just wondering what the stock idle gpu MHz is for the galaxy s4 with the stock kernal? I need to know because I think my phone's custom kernel is overclocking my gpu while idle (320mhz idle gpu) and when I touch the screen it does a reverse boost downclocking to 128mhz until I let go than back up to 320mhz it goes, using KT SGS4 kernel on 4.3 i337M Canadian. I tried setting defaults, clearing data/cache in ktweaker and tried clearing cache/dalvik in recovery too but nothing helps.
everything is 100% stock from fresh flash with superuser, recovery, and custom kernel installed, nothing else.
any ideas would really be appreciated thanks.

Hi,
I was running cyanogenmod 10, quarx's build from 24 Sep 2012 just fine.
Then I upgraded to 2ndboot build (the 20 Feb 2013 one), and now my cpu is locked at 300 mhz.
In the performance options, the min is set to 300 and the max to 0.
I have searched the forums already, and found the approaching post: http://forum.xda-developers.com/showthread.php?t=1764477&highlight=300+mhz
Sadly, I can not change the cpu frequency even in the bootmenu. When I try to do so and reboot, the change is not made.
When I go back in the cpu frequency menu, the settings are reverted back to "boosted", I can not enable or disable the cpu governor.
It seems that the cpu is locked at boot.
I did the upgrade fine I think, wiping cache, dalvik, flashing the rom then gapps, then wiping cache and dalvik again.
The funny thing is, when I try to restore a nandroid backup that I did from my 24/09 rom, it brings me with an empty desktop (not restoring my
data and system at all) which is buggy and eventually crashes.
So I can still flash the 20 Feb 2013 2ndboot build from quarx, but it would be locked at 300 mhz...
Could you please help me ?

I would go all way back to stock then do it all again but remember you should factory reset data and wipe caches jus to be 100% sure that its a clean flash but back all ya apps 1st tho

found a fix !
Ok I managed to change the cpu settings in the bootmenu !
Let me explain: the cpu settings menu is too long for the screen, and it doesn't scroll when I reach the bottom.
So I changed options (from boosted to smartass for example), and then selected "blindly" the last line of the menu, to "Go back".
I tried again, this time not selecting the last line but the previous line (by guessing because the menu doesn't scroll...)
This time it helped and keeped the "smartass" setting !
I'm not so sure that this thing did the trick, it might also have to do with disabling the debug mode in the developpers options of the phone.
So after rebooting, the phone was smooth and fast as before... But one last weird thing is that in the performance menu,
min freq is set to 300, max to 1000 this time, but still on "boosted" instead of the "smartass" that I have selected in the bootmenu
Anyways, now it runs at 1000mhz, which is good enough for me !
I am sorry if I disturbed the forums with my question, then finding a fix myself so shortly, but the phone was almost unusable at 300 mhz.
cheers,

Cpu scaling that's work good and stable for now is "Interactive".
And yes, after changing things in Bootmenu's Cpu settings you need to choose "Save" before going back, or it won't keep your change.
Hey all,
I'm on 4.4.2 stock with Xposed (gravity box).
Using Trickster mod and have tried both M-Kernel (latest) and Faux kernel (latest).
With both, after using the tablet for 1-2 days, the max frequency seems to be stuck on 666mhz (for M-Kernel) and 700mhz (for Faux). I have to manually make it 1.2ghz and apply. Turning screen off/on doesn't fix the problem either. I've tried to remove trickster/clear data but same results. I think it's the same with other kernel manager apps too.
Does anyone have any idea what could be causing this? It's quite annoying
Please, forgive me if this isn't the right place to post this question, I just find the whole forum a little complicated for me to understand (obviously, I'm not a very intelligent person, not even intelligent).
So the thing is a video on YouTube about overclocking the Samsung Galaxy S4 up to 2.3 GHz and I flashed this kernel: http://forum.xda-developers.com/showthread.php?t=2294083
And I had Rom Toolbox and the app KTweaker (the app that came with the kernel) to set the CPU and when I used KTweaker to do so it worked perfectly but when I used ROM toolbox to edit the values my device rebooted, even the smallest change with Rom Toolbox made my phone reboot. I used to edit the CPU with Rom Toolbox before flashing this kernel so I don't think it's the problem.
After that, I wiped cache, data and dalvik and installed No-frills CPU Control but when I overclock my phone with it and I go to KTweaker app to check if both have the same values and the apps tell me different things
Also I noticed that, before wiping, I could go from 1890 GHz to 2300 with no trouble both max and min. After wiping, if I do that, my phone reboots.
Do you think you can help me? At this moment I don't know if my phone is overclocked or not.
Also I editted the GPU. Mainly because of hard gaming.
So what model do you have?
The kernel you flashed is for the Verizon version of the s4. You can't flash a kernel for another phone onto yours.
When I got my LG G2 and had used it for a little while, I noticed some lag and so I researched it. Found out that the interactive governor might help. Rooted the phone, proceeded to install trickster mod and changed the governor to interactive. Actually did help!
But for some reason changed governor back to ondemand and now every time I change it to interactive, the phone just restarts and returns to ondemand. I don't reboot it manually. It freezes and restarts.
Anyone else facing the same issue? Anyone know what's going on? Tried installing busybox on rails to make sure everything was okay. Did have Xposed installed before so maybe there was a conflict with that? I wiped everything using the stock recovery and tried it again but didn't take even then.
Need help. Hate the lag
Install dorimanx kernel and forget about lag

Hi all
I've got a Samsung Tab E T560 wifi version (Quad-Core, 1,3GHz, 1,5GB RAM, WiFi, Android 4.4) and from the first day i got it it suffered from random reboots and freezing.Then i decided to root it and installed TWRP recovery on it,i didn't unlock the bootloader,well not that I'm aware of...Then i installed No-frills CPU Control/SetCPU app to undeclock it to try that and thats when i saw that the tablet was overclocked to 1300mhz max. and 1300mhz mini.,then i tried installing custom ROM that was just ported for this device but couldn't underclock it,i opened the cpu app and set the settings for mini. i set minimum and for max.1000mhz and tried also 1200mhz,granted root and it says successful but it stays the same 1300mhz mini.,1300mhz max,sometimes it gets the mini value on 700mhz,but the max. value stays on 1300mhz...
So long story,short...My question do i have to flash a kernel that supports overclocking and underclocking or is it just necessary to have root?Or do i need to unlock the bootloader.
I tried to find a custom kernel for this device but couldn't find anything.So what are my options as this device is not really so much supported.
Bottom line,i just need this Ta let to function withoit reboot i don't use it for games so it doesn't have to run on 1300mhz for me, just to be stable...
Thank you in advance
