Well the 5 degree difference of our idle phones could simply just be the fact that im charging. When idle my GPU is set to run at 200Mhz, and even when i ran my GPU at lower clocks it would still approach and reach 50 degrees when web surfing etc. But i know for sure its probably going to be slightly hotter when running games, but that's why i raised my throttling temp to 73 from 70. It will just mean more battery drain the longer its running at a higher temp, but id rather that over sacraficing performance. Run lots of 3D applications and for me the bonus 10FPS of overclocking is worth it.

This one is the best compatability for the i337M, and my device is an i337M as well. No issues whatsoever.
[T-Mobile Samsung Galaxy S 4] Tunasty:
Can someone post 07-07 build? I'm not getting better results with this latest build. I've already checked in bbs but nothing seems to be draining like crazy.

S4 is poppin!

[T-Mobile Samsung Galaxy S 4] Bigbabyjesus:
I hate to be a pain in the pee hole but I'm looking for some suggestions on governor/scheduler/voltage settings. I am running omega mf8 with 07/07 kernel. I use my phone heavily in hour long bursts, browsing and photographs mostly, and lately have been getting home with much lower battery than normal. I know this is vague but if there's anybody with exceptional battery doing similar usage on the same room give me some pointers. I'll reward you handsomely via Thanks button!
[T-Mobile Samsung Galaxy S 4] kevinrubio1:
Someone give me some 6/10 settings too :D!
[T-Mobile Samsung Galaxy S 4] Poser:
This is with a little lighter then average use..... And a Combination of kt-mamba settings. I do experience light lag in transitions and scrolling stutter... But this by far the best battery I have gotten.
[T-Mobile Samsung Galaxy S 4] KERKEDAGAIN:
I too am running a kt-mamba hybrid and I too was experiencing stutters. I decided to start from scratch, not a saved profile; found and corrected some issues and things are quite a bit better and I'm anticipating better life than what these screens show..

2 Questions,

Can this kernel be tweaked with https://play.google.com/store/apps/details?id=com.franco.kernel.

And does this kernel support USB OTG.
[T-Mobile Samsung Galaxy S 4] chens23:
Anyone know how to get msm-dcvs governor working? It crashes when I select it
[T-Mobile Samsung Galaxy S 4] ridobe:
Same here. I don't use it, but verified.
[T-Mobile Samsung Galaxy S 4] mamba720027:
To question 1

No it will not work with this kernel cause that app only works to tweak franco kernel.

As for question 2 I retract my previous statement about it not included. As KT answerd it correctly below.

I dont think msm gov will work at all as it supports kernel with 15 max frequency and as u can see this one have more than 15. I dont know if theirs more to it for the reason behind it not working.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Look above for franco answer. USB OTG is built into all SGS4 kernels unless it is removed by the dev, it is enabled on mine and works perfect.
[T-Mobile Samsung Galaxy S 4] mamba720027:
If u still have stutters or mini lags,can turn on touch boost set 1134mhz. Also someone mention if youre on omega rom you could turn off scrolling cache and that also works.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Sorry about double post here,as I couldent successfully edit previous post to add these :p

The latest kernel update,cant say anything bad about it. Heres what it looks like in screenshot while I was out partying over weekend and on the go,no time to charge. I did alot of music playback while phone asleep and used gps few times,browsing and the basic stuff.
[T-Mobile Samsung Galaxy S 4] whytechapel_x:
damn^^. Do you also use that greenify app?
[T-Mobile Samsung Galaxy S 4] mamba720027:
Yea I do use that app,its a must have app.

I forgot to mention I had all 4 cores turned on while I was on that drain cycle in previous post and same settings I posted before with a little more undervolt on key frequencys the phone use, like 189mhz to 1134mhz and 1458mhz alone cause while gameing heavy it utalize that. From -75mv I drop them another -30mv. I cant do that for all frequency as I would encounter random reboots so thats another way I undervolt as my device is not one with good binning to handle heavy UV or OC.

For everyday usability I use same settings I posted few pages back with now haveing touch boost enable plus 2nd core turned on.
[T-Mobile Samsung Galaxy S 4] Closed Source Project:
Please update this kernel to play nice with MG3 (newest base). Thanks :)
[T-Mobile Samsung Galaxy S 4] sgs22012:
Working fine on mg3 on fh for me absolutely no issues

Sent from my GT-I9505 using Xparent BlueTapatalk 2
[T-Mobile Samsung Galaxy S 4] gaww:
Newest base is MGA as in Omega 9.0, and this kernel works fine on it as-is.

If you are having any issues, suggest you restore the kernel's default settings and make sure it is stable, then adjust settings from there.
[T-Mobile Samsung Galaxy S 4] mamba720027:
So I can confirm thermal throttling does not work as it should which was reported by someone few pages back. As shown in screenshot below,my min throttling is set 1134mhz, I have cpu scaleing min set 486mhz but in screenshot you can see it throttles the cpu all the way down to 378mhz which seems weird.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Its a ktweaker issue, its setting it to 1134000000 so it never gets to set values to kthermal since 1134000000 does not exist so it just plummits all the way down to 378.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Ok,thanks for clarifying :)

So if we use another app that have thermal throttling option,it may work properly right? Like trikster mod app,not sure if it have thermal throttling option or work with this kernel but suggesting as an example.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Nothing like that will work. Use Root Explorer or whatever file explorer app u like and go here:

/sys/devices/system/cpu/cpufreq/kthermal/minimum_throttle_mhz

Change the value in that file to the speed you want with trailing zero's. In your case you will set that file to 1134000 for the 1134 step u wanted. U will notice when u open it is will have 3 extra zero's.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Worked like a charm :) . Now I dont have to worry about the cpu freq dropping down to the lowest an slowing down tasks on me.
[T-Mobile Samsung Galaxy S 4] jsr84:
TW Kernel on a Stock Rom, I'm getting random reboots when trying to wake the screen. The captive buttons will illuminate but the screen won't come on, then the phone reboots. I'm running the latest Kernel version, and I have 2 devices this is happening on.

Anyone else having this kind of issue?
[T-Mobile Samsung Galaxy S 4] mamba720027:
Is that with stock kernel settings? If not it could be too low UV values or cpu frequency. In which case you just increase the volt +25 or up the min cpu freq if set lower than stock.
[T-Mobile Samsung Galaxy S 4] TheAtheistOtaku:
i am also getting this, but im on infamous rom. Im overclocking my gpu and underclocking my cpu to a maximum clock of 1.2. Are your setting completly stock or are yours similar to mine?

also, i cant seem to get my phone to overclock the cpu, everytime i turn on oc steps and move the slider to overclock, the phone freezes and reboots, and it has done this on every version of the kernel since release
[T-Mobile Samsung Galaxy S 4] mamba720027:
It just means your device must be one of those in the lower binning and cant handle overclock like others. If it did with other kernels then it could be because some may have increase the internal voltages and such. If you don't experience reboots on stock setting like changeing volt,cpu/gpu frequency and such then its possibly not kernel.
[T-Mobile Samsung Galaxy S 4] jsr84:
Yeah it was on the stock settings. I did a full wipe and re flashed the ROM and Kernel I'll keep you updated.
[T-Mobile Samsung Galaxy S 4] Fazeh:
I had random reboots (2+/day). I fixed it by flashing a different Rom then KT kernel and had no reboots for a week. I switched from Omega 8 to Wanam Lite 1.3. I tried some of the recommendations in this thread on tweaking the kernel settings but none of them worked. I have the T-mobile S4. Such a relief now that I don't have to worry about the phone booting up when unlocking.
[T-Mobile Samsung Galaxy S 4] jsr84:
It **** the bed again. To bad, the phones runs so much better on this Kernel!
[T-Mobile Samsung Galaxy S 4] ktoonsez:
OP Updated

Change Log 7.24.2013

1. Linux 3.4.54

2. Brought TW version up to current Linux version (3.4.54)

3. KTweaker: Fixed issue setting KThermal Minimum Mhz to throttle to. Be sure to go into "Extras->Kthermal" and set the "Minumum Throttle Mhz" to whatever you want

4. Re-wrote multi-core Mhz functions to make it quicker and more efficient

5. Moved code for screen on/off functions to try and help people that have the slow wake issue

6. Move multi-core function calls to a workqueue to try and help people that have SODs ("Sleep of Deaths" for those that didnt know what SOD was :D)

7. Put ZRAM back in for the TW version to help out those monstor ROMs chewing up all available RAM just by booting up

8. More dmesg log spam removed

9. Revert mm: slub: Try setting slub_max_order to zero

10. Some ROW scheduler updates from Linux genious's

11. Sync up with the 3 commits from CM

Hope you guys appreciate this, just got done with a 13 hour day today! :silly:
[T-Mobile Samsung Galaxy S 4] mike216:
Thanks kt on it now! I have this weird bug and was wondering if you experienced it. Sometimes I have to leave a game and rotate the screen to stop very bad lag. I know its not your kernel but wondering if you seen it?

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] pakraider:
Running Wanam 1.4.. The 7/7 kernel build is silky smooth with no jitter at all. Anything newer is very choppy especially in the browser which becomes unusable. Tried a full wipe, but same results. Weird!
[T-Mobile Samsung Galaxy S 4] elesbb:
So i flashed this, and i not only sneezed, but wet myself too.. i dont think i'll ever get used to that xD

Ahahahahah thanks for the update man!
[T-Mobile Samsung Galaxy S 4] PENKO956:
Are you talking about 7/24 as well?

edit: 7/24 silky smooth here, no choppy stuff here.
[T-Mobile Samsung Galaxy S 4] pakraider:
Yep, I had the same trouble with 7/24 as well. Overall the system is slow, and scrolling in the browser is so painful that it feels like you're trying to move a boulder.
[T-Mobile Samsung Galaxy S 4] TheAnarchist1:
Woops Pakraider, accidentally thanked you instead of replaying to you, so have one on me, but I was originally going to say that I have no such issues. :D
[T-Mobile Samsung Galaxy S 4] trueking7:
I hear crickets....

Anyone running 7/24 ktoonsez with omega 9 yet?

Sent from my Galaxy S4 running Omega v9 with Adam kernel 1.5 : good :
[T-Mobile Samsung Galaxy S 4] 2ndammendment:
I actually had an issue with scrolling on some of the 7/xx builds but it's gone now on 7/24. It also varies from rom to rom. Scrolling was so bad that web navigation was almost impossible but after an update from dolphin browser and the 7/24 kernel I'm mostly good on wicked v4 for now.
[T-Mobile Samsung Galaxy S 4] pakraider:
returned the favor ;)

yeah, I hear ya.. that's what makes Android and our devs like ktoonsez great.. the flexibility to tweak things the way we want! :) My post was intended just as a heads up in case someone has issues, to go ahead and try the older build before giving up on this awesome kernel.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Anybody that doesnt flash the right version or trying to put this kernel which is android 4.2.2 on a 4.3 ROM. First ask the maker of your ROM if it is Touchwiz based or AOSP based and then flash the kernel that matches.
[T-Mobile Samsung Galaxy S 4] Te3k:
So I set the suggested KToons settings in the OP, and everything was great for a while... until I decided to reboot. Now every time the phone boots up, I get to the lock screen and then it freezes up and reboots. It's a loop. I think this is because I have the settings set to apply immediately upon startup. Great move, Te3k. What do I do now?

Edit: Reflashing kernel (and clearing cache/Dalvik cache/fixing permissions) had no effect.

Booting into recovery, entering file manager, and renaming the KToons settings APK to .BAK had no effect.

Reflashing 07/14 kernel had no effect.
[T-Mobile Samsung Galaxy S 4] PENKO956:
have you tried flashing stock kernel?
[T-Mobile Samsung Galaxy S 4] 2ndammendment:
I always set my setting to apply 30 Seconds after boot just in case. Maybe try flashing another devs kernel and deleting all the kt related files, then switch back? :confused:
[T-Mobile Samsung Galaxy S 4] Te3k:
Yes, with Odin, and I get stuck at the Samsung white-text splash screen, lol....

That's the plan... I'm going to set it like that from now on. And trying other kernels is the next plan.

Edit: ChronicKernel didn't work. Same deal: get to lock screen, freeze, reboot. Why should that be the case? Wouldn't a new kernel reset all settings?

Does anyone know which KT files I should try removing from the recovery file manager? As mentioned, I already tried renaming the KT settings APK to .BAK, to no avail.

Reflashed the ROM as well as the kernel, with a reboot in the middle and a wipe of the cache/dalvik and fix of permissions. Still nothing. I get to the "Optimizing app # of #" screen, but once it gets to "Starting apps.", nothing else happens beyond that.

-----

Wow, I tried a lot of different combos for flashing and reflashing kernels and ROMs. Nothing was very useful. I might have to bite the bullet and restore a 2 day old nandroid backup, and lose some data. If there's any way around this, I'd love to hear it.
[T-Mobile Samsung Galaxy S 4] PENKO956:
you flashing a .zip kernel in ordin? did you try in recovery? final solution is just flash complete stock rom and start from scratch.
[T-Mobile Samsung Galaxy S 4] Te3k:
Na, I flashed a .TAR with Odin for stock and flashed a .ZIP with TWRP for all custom kernels I tried. It's just so weird that flashing a new kernel or renaming KTSettings had no effect on OC/UV values being set at startup. I wonder where those settings are stored?

I did just end up flashing my two day old nandroid backup. That got me back to where I was before I messed around, but I lost some data in doing so. Let that be a lesson to everyone: make a nandroid before setting any KT settings to load on boot! Even the suggested values in the OP can bork you up.

I added 25mV to the OP's suggested settings and have so far experienced no problems loading settings on bootup, on stock battery (3.8v 2600mAh) or my cheap eBay battery (3.7v 3030mAh).
[T-Mobile Samsung Galaxy S 4] 2ndammendment:
Best way to undervolt is to lock the cpu at each frequency and under volt that one frequency, run a benchmark and undervolt until it crashes, then raise by a bit until it's stable. On my phone I was able to get the lowest frequencies undervolted by 120mv and the upper frequencies by 50mv. Every phone is different though.

Be careful with aftermarket battery's, they may say their rated at a higher mah but in reality they just test the cells in unrealistic conditions to inflate the numbers. I've seen many quality cells out perform higher rated Chinese cells. They can also be dangerous too.

I wanted to flash it but it said error..

Envoyé depuis mon GT-I9505 en utilisant Tapatalk 4 Beta

EDIT :

Now it worls but it's pretty much incredible ..

I installed AnTuTu and benchmarked my S4 ..

With default settings of the kernel my score was : 10281

With the Ktoon settings my scores were : 20607 and 21559

How is that even possible ?

With the same ROM (Barebone v3) but with the stock kernel I made 25696 ..

Where is the problem ?

It surely isn't my phone because I bought it one month ago and it perfectly works with other kernels..
[T-Mobile Samsung Galaxy S 4] Te3k:
You definitely want the T-Mobile version for the I337M. You're in the right thread. Make sure you flash the appropriate version: there's a TouchWiz version for stock-based ROMs, and an AOSP version for other ROMs.
[T-Mobile Samsung Galaxy S 4] Monkz:
I don't think you really read the OP. It explains everything, and leads you to the suggested settings for what your asking for and everything.

Yes it overclocks, and its best to just use the built in KTweaker app for overclocking and adjusting the settings. I think if you read up the post it would answer your questions mate.
[T-Mobile Samsung Galaxy S 4] 2ndammendment:
Same thing happened to me. It's a thermal throttling issue. Not sure if it's because KT kernel throttles earlier than the stock kernel but basically what's happening is the benchmark is putting your cpu under very high load for a long time which is saturating the heat sink and causing the cpu to throttle down to ~1ghz which is why you have a lower score. The truth is that your phone will be faster than stock under normal conditions but it will protect its self from overheating earlier under high loads for long periods.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Stock kernel pretty much doesnt throttle at ALL when running benchmarks. It detects when apps like that are running and maxes all CPU cores, disables hotplugging and pretty much disables throttle all together. If you want same effect to generate a higher random number, turn start throttle temp to 90 in Extras->Kthermal.
[T-Mobile Samsung Galaxy S 4] TheAnarchist1:
Hey Ktoonsez! Excited for some 4.3 love! I tried your AOSP 4.3 kernel, but of course it killed my data completely. I knew it would happen :p
[T-Mobile Samsung Galaxy S 4] 2ndammendment:
What's the max temp our cpu can handle? 90 seems AWFULLY hot. Is it safe to assume that since Samsung throttles at 90 then it's ok If it hits 90 on a regular basis?
[T-Mobile Samsung Galaxy S 4] stevessvt:
Any reason I cant finish an antutu benchmark on any kernel that isnt stock, even at stock settings?

Did you flash 4.3 AOSP ROM and AOSP kernel together on top of ROM with TW based Data?
[T-Mobile Samsung Galaxy S 4] TheAnarchist1:
Gaww: I am not sure if you are trolling, or genuinely asking me a question. LOL!

Oh, and I forgot to specify, yes I know there is no 4.3 AOSP kernel here. I meant the one over in the international forums.

Seriously though, I flashed everything clean, did the typical factory reset and whatnot, flashed the 10.2 build, the proper 4.3 GAPPS, and the international 4.3 AOSP kernel offered by Ktoonsez, and it booted, and everything worked, but my signal was shot
[T-Mobile Samsung Galaxy S 4] Kjc99:
I was having signal issues too... Does the kernel effect the signal I thought it was just modem/radio

Does anyone know how to get my phone to run a little cooler do I just turn the Max down from 1890 or is it harder than that

[T-Mobile Samsung Galaxy S 4] gaww:
Miss-read what you meant by "killed data".

Have you tried Omega 4.3 without a different kernel - it worked pretty good when I briefly tried it (version 1 - new one out).
[T-Mobile Samsung Galaxy S 4] TheAnarchist1:
No, not yet. The performance was not really that bad with stock kernel. I did notice that after a bit of use though, at least right now, CM10.2 performance does begin to slip more than a little. I blame it on the early nature of the build though. Still impressive that it runs as well as it does so early though. I just figured that Ktoonsez was provide a little shot in the arm to remediate the slump. It did, but at the cost of my signal. I suppose just base differences in the international kernel and the T-Mobile kernel somewhere. If there were not differences, we would just have one large one I suppose. :confused:

This is probably a "duh" post, but I just noticed it and felt like sharing. Had fast charge enabled, noticed much better charge rates when plugged to car radio/computer (around 760-780mA range vs 460 without fast charge). I then noticed that while AC charging, I was only getting about 1A... Turn fast charge off and get 1.9A from AC. That's with the original Samsung cable also.
[T-Mobile Samsung Galaxy S 4] Tunasty:
Fast charge isn't going to charge it faster via AC. You saw a difference with plugging in car is because fast charge makes it think it's AC instead of a 12V car adapter.

S4 is poppin!
[T-Mobile Samsung Galaxy S 4] lordcheeto03:
Oh no no, I knew fast charge didn't make AC charging any faster, i had just turned it on one day to charge faster on my car radio and never turned it back off. I had checked my charging current and thought it was amusing to see that, while increasing the usb charging rate, it drastically reduced the AC rate.

[T-Mobile Samsung Galaxy S 4] TheAnarchist1:
Hey guys, for what it is worth, I managed to get the 4.3 Ktoonsez kernel over in the i9505 forums working on my M919 (T-Mobile) S IV. Signal seems fine, camera is no worse than it has been, things feel smoother. I had troubles previously doing this, but I believe it was Philz. I am on CWM Touch, latest, and things are great! Give it a try if you are longing for some 4.3 love in Ktoonsez absence! :laugh:

EDIT: I should mention that I am on Sym_Link's latest 4.3 unofficial CM nightly with IR capability patched in.
