Interesting... im using a pioneer 8600bt and no issues... if its cutting out a lot which I've had in the past even with old versions then its most likely a CPU setup issue..

Simple Solution:

Just change your settings in Ktweaker extras: make "bluetooth profile mhz" 1134mhz.

You should no longer have that issue if choppiness or cutting out is your "flakey" problem.

What this will do is keep your processor(s) from going below 1134mhz, only when bluetooth is on. I find anything roughly below this makes BT music a choppy experience on most music players on an Android phone.

EDIT: kayvt maybe your Ram is super sensitive so try this anyways, but I don't believe this is the solution for you, but it will make it better either way.
[T-Mobile Samsung Galaxy S 4] kavyt:
The music on mine plays fine the issue is that it doesn't like to pair every time. I did not have this issue with the builds from 9,20, or 25. 25 gave me reboots so I'm on 20 currently and the pairing does not seem to have any issues. I am going to test 27 further and try a few things to see if I can narrow it down on my particular device. I am on omega 10 with a Canadian S4.

Is anyone running this kernel with Jamison's Alpha rom? I'm getting awesome battery life but I want to see if I can get even better lol
[T-Mobile Samsung Galaxy S 4] MavereXx:
Might be a conflict between the ROM and that version of the kernel.

KTweaker settings? ZRAM?

What are your settings for KTweaker? if you could start a PM with i would appreciate it! I would like to ask question candidly. Also i found a MOD for ZRAM.......Does anyone no about this?

I set both bluetooth and media playback profiles to 1134, still no love. It is a bummer... I use BT frequently. On Slim Kernel did not have the issue... but it simply doesn't compare in fluidity/performance and batter life to KT.

[T-Mobile Samsung Galaxy S 4] mamba720027:
Just gonna take a stab here,

Are you useing winamp as media player. If so then that could be it as I had experience with chuppy/stutter playback useing that while the cpu is switching cores useing Ktoonservativeq in the past. Havent tried it back since updated kernel a few times now as im useing jetaudio media player.
[T-Mobile Samsung Galaxy S 4] MavereXx:
That's what the 1134mhz recommendation was to fix.. choppyness on winamp and other players.

By the way I just bought a brand new pioneer deck and it works perfectly so it must be a new conflict between the omega ROM and kernel

[T-Mobile Samsung Galaxy S 4] Poser:
It is a combination of choppiness, audio rate flux and cut out. However I flashed chronic to see if the issue persists, and it did not. I am on slim 4.3bIV. So the stock slim compile and chronic both do not experience the issue, but, for me do not have the performance nor battery of KT.

I will continue working on it.

Also, the only media apps are use are MX, Pandora and play music.

booooom
[T-Mobile Samsung Galaxy S 4] mamba720027:
Ok,kewl. That may work in my case since we dident had the option media player mhz to set back then.

How about try useing a file manager such as root explorer to delete ktweaker app @ "system/app"

Reboot into cwm

Reflash kt kernel

Fix permission

Reboot

Reopen ktweaker and "load defaults", close. And see if problem persist. Do not load any old saved settings.
[T-Mobile Samsung Galaxy S 4] MavereXx:
I dont trust the media player mhz setting as ive seen it run that minimum even when a media player is not running on version 8/27

I've tried the updated kernels but for some reason battery is not the same. rather than have new options/settings. Ill rather have better battery life with old features. I don't need min music MHz or gpu uv or zram etc... imo 7/7 is perfect right out of the box, no reboots or issues what so ever.

I keep going back to 7/7 cause of random reboots.

I not trying to be a smart ass but I use my phone a lot and need it to work 100%. this is just letting anyone out there know that if you don't need the "new features", you can get excellent battery life on 7/7.

I understand kernel is in development and I salute Mr ktoonz for his excellent dedication of achieving the best kernel out there and everyone else who is out there in the front lines testing. :good:
[T-Mobile Samsung Galaxy S 4] MavereXx:
I had random reboots with 8/25 but 8/26 fixed those problems. It's completely stable now my phone never reboots ever. If it does with the latest version you put some incorrect settings in, like restoring your 7/7 settings which are incompatible and the file will never work with the new versions.

[T-Mobile Samsung Galaxy S 4] mamba720027:
Thanks,I kept default max cpu clock speed for battery profile because I don't believe in limiting the cpu speed for such an awesome device :D
[T-Mobile Samsung Galaxy S 4] MavereXx:
Lol yes you do look at those thermal values, it will hit those and underclock ALL the time.

P.S. Serious question: On your performance profile how can you run 600mhz on the GPU which has a stock max of 450mhz and undervolt from there to operate at 1075mv @ 600mhz instead of 1150mv @ 450mhz stable?

Sent from my Galaxy S4 i337m
[T-Mobile Samsung Galaxy S 4] mamba720027:
Lol I know what you mean but thats just feature not general preset as say for example 189/1700mhz max. Besides the only times it throttles is mostly gameing and watching long lengths of movies which is fine because if by throttleing the cpu helps reduce heat then its helping to reduce battery drainage waste. That is why the thermal limit is set at various points in each profile for different circumstances. :cool:

Second question

600mhz GPu if I drop the voltage -25 more it will reboot,not imediately but ill get artifacts when apps open and animate.plus games will FC. 1075mv is my stable point on the High. Maybe im lucky that I can undervolt and overclock it that much. I also did delete ktweaker and follow recommendations by KT when I installed the last update so everything is valid. I was also puzzled at how much I could UV the gpu side untill I enconter few random reboots after days of testing but these voltage settings are final and stable on my side after running for few weeks with games,movies,music,texting etc.

[T-Mobile Samsung Galaxy S 4] MavereXx:
J

Ive found the m919 handles CPU undervolting worse than the i337

On the other hand I find the GPU on the i337 handles undervolting worse than the m919.

I'll take your GPU voltage lows into consideration on my next versions of tweaks which are going to be device specific instead of for all sgs4's :) btw your CPU voltages can drop a bit with no performance loss check out my m919 stable super bull 1.4 for the CPU voltage table.

[T-Mobile Samsung Galaxy S 4] mamba720027:
That is true although I don't understand as much since Qualcomm integrates the cpu+gpu into one slab I figure I wont achieve the potential to undervolt as much on the gpu or cpu side as I fall in almost last in product binning :D

Youre right about the M919 CPU handleing undervolteing worse cause as you can see mine and thats as low as it will go,believe me I spend lots of time trying UV the cpu lower and it will reboot sometimes after u use it thoroughly for long. So thats my absolute stabe limit on the cpu side.

I may still try your voltage table just to see after this drainage cycle :)

I just did an update to make it compatible with the i9505 who doesn't like GPU undervolting so much. Tricky business making a setup for all.

I haven't had any issues with it getting hot, and he says this fixed his getting hot. So we have:

2 for not getting hot

and

1 for getting hot

Though it's still early in development, I think if there are any issues they will get worked out. Based on his "Woooooooooooooohoooooooooooooo" and screenshot I'm going out on a limb, and saying that he got the bootloader unlocked.

I got similar results infactt better battery on stock and MX player would soft reboot android on 1080 videos
[T-Mobile Samsung Galaxy S 4] mamba720027:
Did you try add +25mv on the high side of GPU and retry watching a 1080p video. Mostl likely it was UV too much. Or try the above and choose performance governor for GPU and see if you experience same problem,then switch from 504mhz to 320mhz then the lowest. Run it this way for at least 20 minutes watching 1080 video. If you experience reboots or stutters,fc add +25mv or +50mv to that frequency(s). Good luck. :)

Also use cpu spy to keep an eye on what cpu frequency it uses most when watching such a HQ movie then add +15mv or +25mv to that frequency an make necessary adjustments to the lower frequencys below it. Sometimes its the cpu and not gpu or a combination of both. And other times its beyond me :D

You could experiment, turn off "gentle fair sleepers". Never experienced this except if I undervolt too much. Also you could possibly try set GPU screen off profile from 128 to 200mhz if you have that setup. Just some ideas to work with.
[T-Mobile Samsung Galaxy S 4] PENKO956:
to be honest I didn't try to undo any UV on your 1.5 settings. but non of the anomalies mention on my post happen on 7/7. mx is flawless, phone doesn't take to long on incoming calls. I went back to 7/7 yesterday and for sure 7/7 gives way better battery life. im at 41% still from yesterday with 3hr screen and 1hr voice calls. on 7/7 all i have to do is change gov to kt/row (set it and forget it) and your good. theres no UV OC GPU. works fine out of the box. seems like the more features added to the new kernel,the more it requires a little tweaking than usual to get the best results.
