Whats ypur stock volts look like and are you overclocked. If you overclocked to 750a7 cores it may be the issue only some were stable on that. Please provide all info you can on how you setup stweaks etc.

Edit: Kind of like Andrei is saying you have choices beyond stock on here. Personally mine has ran stable on 100(200mhz) minimum since Andrei graciously added it for us. My volts stock for my bad binned cpu is 950mv from 100(200)- 350 (700)mhz on my a7's. Cpu runs like a champ though so I don't mind the higher stock voltages. Enjoy the great freedom of Andrei's kernel or move back to stock or another kernel. Your cpu's overclock, underclock, overvolt, undervolt ability is not kernels fault. With these cpu's we get what we get. Try my volts and try not overclocking your a7 or a15 till you stabalize your minimum mhz you are attempting. One thing at a time. This way if you have errors you know what did it and why. Kernels aren't magic pixey dust that turn your phone into enhanced hardware. Your cpu's limits will be the same on all the kernels. Take your time and test methodically or you will find nothing in your tests and just have wasted time spent testing. If you have any ranges undervolted or overclocked set them back to default and just work on the min mhz. Also just use Stweaks and no other app to set everything.

Some users use setcpu profiles ability but I suggest you get stable before doing anything fancy. I always set on boot for all the options i have set in stweaks and it works fine. The fault is elsewhere than set on boot option.

Nobody is forcing you to run it like that. I made those frequencies available only for testing and nothing else.

I have a question. Do you guys have WiFi for root users running on your phone using this kernel??
[Galaxy S 4 i9500 Original Android Development] dragon135:
All is stock settings, I only change minimum freq to 100Mhz in Stweaks, nothing else.

It is stable, I always use it and no problem since andrei added this feature. The problem is only after power off and then on again it will hangup and restart after 2 minutes if I tick set on boot.

Well I guess I need change the voltage and restart to check if it is stable.

Hey is there really any sound problem? That's what keeps me from flashing this kernel. . But I know it's one of the best.
[Galaxy S 4 i9500 Original Android Development] mw86:
There really isn't a sound problem. It was fixed long ago and for the rare user that had it still a shutdown and power on fixed it.

No sound problems here too.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I never fixed anything regarding that and we still don't know what caused it. That being said, I only occurred it maybe twice this month (And I flash a LOT!), so it still happens sometimes.

If I dont change settings in battery section of the settings device will be normally charged right? Also does over clocking to 1.8 ghz will do any notable gain in user interface or apps against additional battery cost?
[Galaxy S 4 i9500 Original Android Development] mw86:
This was posted earlier in thread. It is up to you, power efficiency drops the higher the mhz you use and the hivher you push into a15 ranges. 1700-1900 must take near 2000mw and the device can only supply as much power as the battery can output in a given second. If 1.7-1.8 seems to destabilize in heavy loads I would try to undervolt those to get power consumption closer to what 1600mhz uses, though obviously it will never use the same mw power draw as it will always be a bit higher. Goal keep power consumption of cpu under 2watts was probably why this cpu came at 1.6ghz. That and heat issues in those ranges.

In chainfire bench one of the heaviest on the play store 1.7+ on stock volts ive had a black screen on stock volts. Not a reboot which often indicated either too high mhz then what is stable or too low voltage. Instead this I figured to be a crash from lack of power. I have feeling 2watts is the power limit before protection circuitry kicks in. After i undervolted only slightly the ranges from 1.6-1.7 I was able to pass many runs in a row and endure the high heat of that test without a crash. This stayed tru e for multiple benchmarks. So I use 1.7max. I've been able to bench at 1.9ghz before but what does a bench score matter if it comes from a mhz that isn't stable. So it is more beneficial staying in ranges which we can fully utilize.

These are what I use on my low efficiency binned cpu ie has highest stock volts available...

1500mhz default: 1137500 set: 1137500

1600mhz default: 1162500 set: 1137500

1700mhz default: 1200000 set: 1137500

Lockscreen

I am having problems with my phone's lock screen when I touch it. STOCK ROM and your latest KERNEL with the CAMERA FIX flashed as well. The lockscreen is not working well as in the touchscreen does not respond. I have looked at various forums on XDA and read that it might be related to your kernel do you have any feedback on this. It only has problems in the lockscreen. Please let me know. Thanks.
[Galaxy S 4 i9500 Original Android Development] mw86:
Andrei, first I would like to say I never wanted to create any drama or issues in your threads whatsoever. I have always enjoyed your incredible kernel and it was not my intentions to have caused drama. I am just a quiet friendly person which if I can I to give users advice. The mod I posted will not have cputuner in it very next release as to avoid any issues with development/developers work. It is not my intention to stir up the pot now that stuff has settled but to clarify any point of issue all came from that aspect first before anything else was came about. Thusly I just wanted to be sure you read that post before it was all cleaned, that the aspect I just mentioned is no longer a part of that mod and the words used in the script was apparently not marked to be rude but was actually a American reference to a sitcom Seinfeld where in a comedic scene plays out in a soup kitchen and a guy called the soup Nazi over little silly things would say no soup for you. Hence the way it was written in the script. It was setuo that way due to user reports but clearly was a silly way to stop issues with two cpu apps conflicting. The user has removed the cputuner and there in any blocks of any apps which were previously there. The whole start of it was a misunderstanding and that user would of immediately then removed that part of the mod if he had found out sooner that was what caused so much upset. Lot was said and tensions rose and I apologize anything happened at all on mine and everyone involved behalf. Btw if you would like I will even remove that link from my post from your discussion thread. I just want peace. If anyone checks my posts I make I am a non confrontational person who would rather everyone works out issues in a calm peacful way. (i understand the way it went down there was nothing peacful about it but as for my involvement I don't want conflicts, the user didn't want any either as he as soon as realized the root of issues acted on fixing that)

So I formally apologize for all issues that were from me and my post Andrei.

I am not sure if this was ever reported but the pics above show what I set in stweaks for boot. For some reason perhaps unique to my phone setup alone but I set noop for internal external sd and everytime upon boot the external sd is set proper to noop but the internal stays on CFQ. Now if i go to stweaks set another scheduler then set noop for internal i check and it is set proper. It seems the only issue for internal scheduler and stweaks is applying internal scheduler, atleast on my setup. Could this be something on my end blocking or causing issues with stweaks applying internal scheduler at boot?
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I didn't blame you for anything during any time, I was just expressing my disbelief at that guy. Furthermore his CPUTuner was irrelevant, it was only changing cpu policies [Making the blocking of third-party apps even more irrelevant]; the most damaging stuff comes from the scheduler configurations, or should I say mis-configurations. He already proved that he's a crook [And temp-banned for it] and I sincerely doubt he understood what he did in terms of scheduler mechanics if he couldn't properly manage script variables and loops inside his scripts.

Odd. I'll look into it. Anyway next release will see the death of STweaks so things will change in terms of configurations.

hi just want to ask if i can use this kernel with no issues along with omega v10 (GT-i9505) ... i have been desperately looking for a stable kernel which is battery friendly :) thanks in advance for the reply :)
[Galaxy S 4 i9500 Original Android Development] alvaretto:
Hi mates!

I used this kernel when I had my S3 and I just got my S4 recently so I decided to flash. But now I have a question. Don't know if it's been answered before. Why is 600MHz the maximum freq for A7 cores and not 1.2GHz as I've read. Is it for battery life improvement??

P.S

I just really don't know. I'm not asking for a change or claimning there's a bug or something like that. Just want to get to know this device and be familiar with it in this terms. Sorry if this has been asked already.

Thanks!

[Galaxy S 4 i9500 Original Android Development] powell21:
thanks 4d help sir :) really appreciate it :)
[Galaxy S 4 i9500 Original Android Development] runedrune:
It is 1.2Ghz. When it shows up at 600Mhz that actually means the A7 cores are running at 1.2Ghz. Like at 500Mhz, the A7 cores are actually running at 1Ghz. Anything higher than 600Mhz is the A15 cores.
[Galaxy S 4 i9500 Original Android Development] alvaretto:
Thanks mate!

But... Why is this? Is any specific reason to represent 1.2GHz as 600MHz?

I just don't understand :eek:
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
It's a technical reason internal to the workings of the kernel; because otherwise the A15 and A7 frequencies would overlap. Representing the A7 cores at half frequency is a simple workaround that avoids changing a lot of code in the CPU drivers of Linux.
[Galaxy S 4 i9500 Original Android Development] Ryanrioz:
sorry for asking question

is taht after flashed kernel taht will have the roots at your kernel?
[Galaxy S 4 i9500 Original Android Development] mohammed510:
Anyone tried to under clock A15 cores to 800mhz ?? For me all heat issues are gone.

Also tried to underclock the GPU to 350mhz .. Really can't notice any differences.

In my opinion I don't think that android needs faster CPUs it just need some ram optimizations because my phone uses more ram when nothing is running then my windows 8 laptop!?

What do you guys think??

Edit: it looks like the stock TW launcher is slower than other launchers like for example Nova or Action launcher, it somehow give you the impression that the phone is slow and laggy after having lots of apps installed?!

Edit 2: Trickster Mod app has the frequency lock feature which will keep the A15 cores at 800mhz according to CPU spy reborn app.
[Galaxy S 4 i9500 Original Android Development] mw86:
Anything you can do in trickster like that you can do in Stweaks which is overall a better setup where Andrei exposes only the available options for our phone so cpu, gpu, i/o, screen and audio are greatly controlled and adjustable thanks to Andrei implementing into the Stweaks interface. But next kernel should have a much more amazing setup as Andrei is moving kernel control completely out of the app interface of Stweaks to a whole new setup, which sounds to be a better description direction than the app interfaces like Stweaks, Trickster and other apps like this. Using less apps to save resources seems better.

Lowering your max mhz especially capping A15 max will definitely lead to more efficient ranges being used even in heavy loads as they will take less mw far less than per say stock 1600mhz. In fact instead of being a linear curve for power draw as mhz rises from min a7 to max a15 it is up until around 1200mhz a15 then you see more of an exponential spike in power draw every mhz you over 1200mhz a15. If your really trying to save power in a day of basic phone use capping to a7 max supports an even better power efficiency then even that 800mhz a15 minimum as your max mhz.

See 16 posts back the mhz power draw chart.

I moved from stock like launchers to basics and I use Smart Launcher with widgets disables I just use shortcuts and it use low resources and moves fast. I use around 35~mb cached ram for this launcher and it has been nothing but fast and lightweight on resources. https://play.google.com/store/apps/details?id=ginlemon.flowerfree

If i ever find an even better on resources launcher I plan to use that.

Btw sure using 350 max on gpu will help keep power draw down your just drop some rendering power. Should be fine as on web pages rendering is done more by the cpu as Andrei has mentioned in his Octa explained thread, it is one of the heaviest real world loads on a phone or mobile device.
[Galaxy S 4 i9500 Original Android Development] Alphadan:
Hey guys,

I just wanted to let you know that I'm let down by the fact that this kernel is not being developed for 9505... Back when I had my S3 i couldn't live without Perseus kernel. The fact that it's decided now that there won't be a 9505 variant reeeeeally sucks donkey wang.

It was good while it lasted.

[Galaxy S 4 i9500 Original Android Development] mw86:
This sounds great Andrei. Stweaks from the get go seemed like a constrained interface for all the options you exposed for your kernel for all of us, users of Perseus.

Btw Voltage Control apk seems to successfully set mmcblk0 scheduler via the option to make an initd to set the couple options exposed in Voltage Control. This was one of the few ways automated at this time now that I was able to get the scheduler to not be cfq when I checked manually after boot.

The contents of the script that worked is below. Simple script i had been using to just set via echo command to that location wasn't sufficient. This one below is property of Voltage Control apk from playstore.

Is it possible to implement something that will automatically remove the A15 800MHz step if your max A7 speed is set to 750MHz (1500MHz)??

An A15@800MHz should have similar performance to an A7@1500MHz, so there should be no need really for the 800MHz step.
