HI . One question. Im using a custom kernel and its cool but i wanted to ask you something about kernels in general .
In all the phones i've been using , no matter if lg , Samsung or Sony , stock or aosp . All the kernels (stock or custom ) work the same way .
Ir i dont touch the screen, its at 200 mhz and if i touch it , then it jumps to 600 until i stop touching the screen . It never uses the other values except 1200 sometimes . This way of going up and down the values eats the batery of all my phones . It is a solution or i im doing something wrong ?
Please someone help me because i dont know why the same bug follows me no matter the rom , kernel or phone

It's not a bug. It's a kernel feature. It's called "Touch Boost" and it implies that, every time you touch the screen, it boosts the CPU to a certain value. That value can be set, on some kernels, by the user. Other kernels don't have the option to set the touch boost and you can't do much about that.
The features should ensure smoothness. On most kernels of the S4 the touch boost is set to 1134 MHz. Setting it to a lower value will cause the UI to lag a bit.

SO this is weird what im about to tell u is trick and a BUG so how is that possible here is how ::
When i open a game on my hd2 especially a hard on the graphics one like lets say { into the dead or beach buggy ]
u see when ever i start these gaames they freeze so how do i make them start and unfreeze the system .
JUST PUSH THE POWER BUTTON FOR SEC just like ur turrning the screen off not force shutdown the device or any thing
and click it again it will open the lock screen so open that and u will find the game working and actually very playable .
Its weird and the only workaround for it is by installing chainfire 3d but the problem is that most roms aren't compatible with it and if u install it on any ROM and reboot it may not boot again unless u reflash that ROM ...
So devs any easy fixes for this bug ""?>:":?>
Interesting solution, thanks for the info. One thing I have to point out though is that people will have to be careful doing this if they underclock their CPU when the screen is off as they may need to battery pull and restart. I tried listening to music with a 128MHz underclock on my HD2 once and the screen just wouldn't turn back on.
Does underclocking increase battery uptime? Cause as far as I know, the Voltage on 460-128MHz does not differ (atleast as for my kernel (example)). Therefore it won't change the draining of the batter - am I right?
If there is any difference, its very miniscule. I think leaving the CPU profiles as they are is probably the best solution.

Hi all,
I am a normal android user and of course I like mod, flash and modify my rom.
About the rom the choice is very personal, but what about the kernel??
Ok, I can make undervolt, overclock and sometimes change governor...every kernel now have such features..
maybe something is different for sound settings or color settings, also very personal...
So, which is your idea behind the choice of your favourite kernel ???
I try to choose a kernel with good combination of performance and battery life. Battery life being top priority. I monitor deep sleep, and time spent at various frequencies. Of course that requires a lot of testing.
Kernel choice is based on what works best on YOUR phone...so you need to back up, flash the kernel of choice and see how it reacts to how YOU use the phone.
Happy Flashing
i buy a Galaxy Grand 2 SM-G7102 ..Grand 2 is a great phone... and i installed Custom TouchWiz / Prerooted Rom on it .. but.. when i use all cpu app on play store Even Setcpu ,i cant even change or stick the min to EX:1.12 Mhz ... i try the max and it work... so just the Min... and maybe.. can you help me with this... because i want to make profile in screen off to save power .. like that .. so dev.. hope you can help
Hi everyone,
Thanks for reading this . As specified above, my phone has a rather serious problem of overheating. To try and reslove the issue I tried modifying the CPU frequency, to set it low enough. And a very bizarre thing just happend.
Opening Kernel Adiutor, I saw that 4 out of my 8 cores (the 2.5 ones) were running normally. No overclock, stock settings, stock governor and so on. The issue seems to be in the other 4 (the 2.3 ones). Both the minimum and highest frequency allowed is set up to the same parameter (1556 mHz), forcing it to stay at maximum clock all the time. I tried modyfing via Kernel Adiutor the settings, lowering the minimum frequency allowed to stock one (which should be around 300 or something), but it had no effects: it immediatly comes back to 1556 and just won't come down.
All of this started happening after i removed Franco Kernel from my system, flashing another ROM (Chroma) with a different kernel altogether. I'm currently on Cataclysm ROM and after doing a clean install, formatting internal storage as well as every other partition, i couldn't resolve the issue. Moreover, Kernel Adiutor sometimes won't even show my CPU settings, stuck on an infinite loading. If anyone could help me, it would be much appreciated. It's really important. I'm by no means Android expert but i do have a rather basic understanding of ADB and so on.
Thanks a lot for your time.

I used to own a n7 and that allowed me to set min and max freq. with apps fine but i am also seeing this on my 6p, i don't notice any "overheating" although it may be due to me being used to it always running hot since i run a lot of heavier programs and also you know... SD810 but i guess it does the frequency thing as a way that frequency is actually controlled on this platform or something, because it sticks fine to the limits you set while flashing a kernel but no app can get it to stick. Then again this is just me sharing my experience with it as it is my first phone with this platform, so maybe someone who knows more about this could offer some help.

Thanks anyway, i really appreciate it!
well my phone cpu is always around 40 - 50 at any clock ( 0.8 to 1.2 ) and this produces a heat around the screen ( the phone is blazing fast and smooth consumes a fair amount of battery ) i 've installed before many roms and this problems started when i first used root booster with 6.0.1 then it presisted with any rom i install even flashing official rom don't change the config
my questions is is those thermals normal ?
can somebody screeshot CPU covernor tunable from kernel auditor
and how can i reset my cpu original setting

You have made similar threads/posts before CPU kernel and settings are reverted to original when you flash a stock rom. During summer, my cpu was between 40-50 and now it is cooler. It depends of what you do with your phone. For example, mobile data - GPS can cause heat to phone.
If you think that something is wrong with your phone, you can bring it to a service... although i dont trust anyone unless i see with my eyes what they do.

i am at minium use and the phone hits up flashed stock rom but the problem is always consistent
