I'm happy to say that KT ASOP kernel works now on PACman, 5 July build. I get no force closes of the phone apk and I'm able to make and recieve calls now. I'm also not having any random reboots either on this kernel.

Now I am having an issue now of my network data not performing as advertise.

I'm not getting LTE anymore, checked my access point names all is correct, searched through KT tweaks for any thing to do with network and can't find anything that is related to LTE. Also my 3G, HSPA+, and DC speeds are lagging on streaming audio and file downloading.

Is there something I missed in KT tweaker or is this a another kernel & ROM capatiability issue?

I'm going to flash the new 08 July PACman Build and test out KT on it again.

I really love the power savings and performance on this kernel and tweak app.. I have extened my battery life by at least 50% with this ROM and i would really like to see it work with PACman.

Ktoonsez keep up the great work
[T-Mobile Samsung Galaxy S 4] ktoonsez:
Thanks man. You will have to trace it down in the ROM since the kernel has zero effect on data in the way you are talking about. What I would recommend is make a backup, fully wipe the phone, then install the ROM ONLY and boot up once, then go back and flash the kernel.
[T-Mobile Samsung Galaxy S 4] Tankrat:
Thanks, that's what I figured...

LOL ah the fun of backing everything up :rolleyes:
[T-Mobile Samsung Galaxy S 4] Tunasty:
How's the battery life coming for you guys on this update? Mind sharing some pics? And is it with KT's recommend settings? For some reason I can't hit 5+ screen time anymore. Now that was just by following the recommended settings.

S4 is poppin!
[T-Mobile Samsung Galaxy S 4] mike216:
What version are you running. I've been using the recommended settings and things are right around 4 hours over 19 hours of idle time.

Things are good. Sometimes I get some idle drain out of nowhere. My wake locks are fine. Sometimes I think the battery just isn't calibrating properly and it looks like battery drain when it's just getting itself where it should be? What do you guys think on this. I feel like I'm watching to close sometimes :)

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] Tunasty:
I've tried every single version except this latest one. I believe the build that was before 06/10, was giving me 5+ hrs screen time easily without even greenify but I lost that build. Ever since then, I barely get 4+ now. Idle time is fine but not the screen time if thay makes sense

S4 is poppin!
[T-Mobile Samsung Galaxy S 4] mike216:
Do you sleep with the phone on the charger? If not what do you lose over 8 hours of idle time?

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] mamba720027:
You maybe right about the calibration cause a few times my phone would drop for example 64% I leave it and then I go to use it again and its at 65% :D . But after I let it drain to about 5% one day and recharge I yet to see that happen again.

[T-Mobile Samsung Galaxy S 4] mamba720027:
So far this what my screenshot usage looking like and my settings. I Cant say anything bad about battery and performance, everything runs fast and smooth with battery to spare now.

CPU MIN/MAX - 189/2052

Cpu UV -75mv

I/O Scheduler - Row

CPU Governor -Ktoonservativeq

Extras

screen off profile - 702mhz

screen off GPU max - 200mhz

Vibration strength - 50

mdnie scenario - eBook Mode

SDCARD SECTION

Internal Read Ahead buffer - 1024

External read ahead buffer - 1024

GPU SECTION

And I tone down my screen brightness with lux autobrightness. Rom power saveing turn on except for cpu. And used Greenify app to prevent apps from running with screen off.

Also something im experimenting with was the row scheduler settings in screenshot below.

Oh okay. That would explain it. I feel stupid now, lol. Thanks man. Can I just flash it on top of this one or do I need to reinstall ROM, go through setup and then flash new version?
[T-Mobile Samsung Galaxy S 4] mamba720027:
Was going threw the page,everything looks good but I think some the stuff on droidphile page not accurately cover of our current cpu like setting the cpu freq parameters for hotpligging and other bits of pieces stuff. Looks like it wasent updated in a while but very good guide. Also would be kewl if a brief introduction/explination of ktoonservativeq governor was explianed on the OP :)

Sharting isn't fun either.
[T-Mobile Samsung Galaxy S 4] tichs:
when i installed this i oc'd to 2.1 and the phone scores were extremely low, from stock cm at 1.9ghz antutu is 21000 with this is 8000~? why is this so slow some tweaks break some core functions i guess?
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
The scores will always vary, especially when on an AOSP ROM. You can't base overall performance off benchmarks..
[T-Mobile Samsung Galaxy S 4] tichs:
the phone was really slow overall and got reboots, idk why, i don't always rely on benchmark but it definitely made it worse.
[T-Mobile Samsung Galaxy S 4] mamba720027:
:D

You said you overcloced to 2.1, not because a device run for an hour or few minutes means its a stable clock speed,same with UnderVolting. One of the effects you would encounter is low benchmark and slow system response,data corruption, in a case like that which I believe is similar to what you experienced.

Also before useing a custom kernel its good to cleanout any cpu/gpu configuration scripts in "system/etc/init.d" . Thats another thing that could contribute to slow system,reboots and such.
[T-Mobile Samsung Galaxy S 4] norml:
Speaking of benchmarks, can you guys recommend what settings to change just for testing? So far I learned to change the io sched to vr and the cpu gov to performance.
[T-Mobile Samsung Galaxy S 4] mamba720027:
I usually just set governor to performance. Dunno what other techniques others use or a benchmark person. Since we on the topic heres what mine is below with settings I posted on previous page.
[T-Mobile Samsung Galaxy S 4] norml:
I asked about this awhile in the INTL thread I think, no one replied. Haven't seen anything about benchmarks settings in any of the ktoonsez kernel threads. Here are some of my scores.
[T-Mobile Samsung Galaxy S 4] mike216:
I tried some of your settings mamba mixed with KT's recommend settings. Battery life was unbelievable. You restored my faith in screen off profiles. I think my phone didn't like the low 486 for screen off.

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] mamba720027:
well its pretty much about finding your highest cpu/Gpu max stable speed then switch the governor to performance. Put the device in airplane mode,freeze background apps. Thats what I rember from the nexus s forum long ago about doing a proper benchmark.

Yea 486mhz is too low.you need a frequency that when the screen is off the cpu is able to efficiently complete the task as quickly as possible and throttle back to the lowest frequency. For me 702mhz was the lowest that could do such a task and save battery. Good everything worked for you :)
[T-Mobile Samsung Galaxy S 4] Tunasty:
Mix match settings of KT and Mamba:

Screen shots of your settings?
[T-Mobile Samsung Galaxy S 4] mike216:
I really don't care much for bunch marks but this one was impressive. I'm more into getting that perfect balance between battery life without sacrificing performance

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] norml:
Impressive indeed! Very high. I would like exactly what you wish, one prefs for getting the best of both worlds, one for extreme battery life & one for all out performance, which would probably be good for benchmark tests as well. I think it's inevitable that one's settings will be changing all the time, for whatever prefs one chooses and it is a never ending, ongoing process.
[T-Mobile Samsung Galaxy S 4] pilo99:
what are your set up for the display

i do love this kernel and been struggling to see what is the best display configuration you guys are using , any one care to share the values of the display
[T-Mobile Samsung Galaxy S 4] mike216:
64gb card running great. I did have to format in Fat32 to get my nandroid backups on it. It did work out the box if your not worried about backing up nandroids on it.

Woke up today with 99% battery left. That old card must have had bad data on it? I usually have around 96% left.

KT have you ever heard of a bad memory card draining battery?

6. Async I/O latency to a ssd greatly increased, 34% gain (Creds: kleikamp)

7. KTweaker: sched: Make GENTLE_FAIR_SLEEPERS configurable thru "Extras" screen

ENJOY!!!!!!!!!!
[T-Mobile Samsung Galaxy S 4] whytechapel_x:
Nice. One question though. I'm running task's aokp and was wondering like when he releases a new version and i want to flash your kernel but the thing is that it will be older. Will i be missing features that he incorporates into his updated kernel? Just asking because I love runing both of your guys work on my phone lol.
[T-Mobile Samsung Galaxy S 4] ktoonsez:
99% of the time you can mix and match. Every once in a great while Cyanogen will do some crazy code that involved the display driver and you wont be able to do that but like I said, its not very often and usually task will state NOT to flash another kernel when things like that are present. :good:
[T-Mobile Samsung Galaxy S 4] whytechapel_x:
Awesome!! Thanks!!

Things got really green? Unless I'm just too tired xD thanks for the update boss! Btw you get my pm?

Should i still stay with faux123 or KT kernel and im running the Wicked v4 rom. What kernel is better?
[T-Mobile Samsung Galaxy S 4] ktoonsez:
I didnt get any new PM.
[T-Mobile Samsung Galaxy S 4] CamFlawless:
That's a question of personal preference that will vary depending on individual devices and the user's goals with flashing a custom kernel. No one kernel is "better" than another given these variables.

The best thing to do is flash for yourself and give it a few days to see how it works for you.
[T-Mobile Samsung Galaxy S 4] rel500:
Not to derail the thread but blacklabel2020 can you try the dual mode using faux and see if if works? Mine is broken. :sly:
[T-Mobile Samsung Galaxy S 4] elesbb:
Interesting :P I sent you a message with a last kmsg without the qseecom in it :) it's gone :) :)

And I must have been delusional because I don't see green anymore xD
[T-Mobile Samsung Galaxy S 4] mike216:
I don't know much about what's been changed to have a educated guess on what's been tweaked or improved. Was this version built to improve speed or battery? Anyone understand the changes and maybe enlighten me. Thanks in a big noob when it comes to kernel code

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] ktoonsez:
All of them are for speed and better memory management.
[T-Mobile Samsung Galaxy S 4] mamba720027:
To make things short, gentle fair sleeper if enable supposed to save on battery,leave off improves

UI responsiveness. Lockout core 1,2,3 set to 2 means those choosen cores off. Suppose to save on battery and if set to always on then the core will always be on and means high performance. Coarse set to normal just means normal hotplugging letting the governor do its thing. The kernel can be used for performance or battery but as you know its already hell fast as it is :)

Thanks again for adding the core control features, now I can setup and save some profiles to use at work n home :)
[T-Mobile Samsung Galaxy S 4] mike216:
Thanks KT and mamba, you guys are always so helpful and patient answering my dumb questions. Much appreciated

I asked because this kernel has been so crazy good on battery im just really hesitant on touching anything. I haven't had battery life like this ever. I woke up today to see 99% battery left. Best idle drain I've gotten! As always the kernel just gets better and better so I'll just shut up and flash it :p

I'm assuming the KT settings are still up to date?

[T-Mobile Samsung Galaxy S 4] mike216:
I did the suggested settings. I'm thinking the (sync extra cores and touch boost cpu all cores) set to 1 should be better in battery. If there able to get the job done faster then that should actually save battery even being enabled

Hey mamba I was curious if you also go with kt settings and choose 1 under (sync extra cores and touch boost cpu all cores)

This seems like it would be more battery heavy but not if the job is able to be completed faster? You've been there and done that in kt settings. Thanks

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] mamba720027:
Yes I choose 1 under sync extra cores but not 1 for touch boost cpu all cores,just for 2nd core. For all cores it should make everything feel much smoother and much responsive,I suppose its best to leve it on 1 cause touch boost frequency is 1134mhz and the cpu uses that frequency very often to get things done so you looseing nothing much. You can experiment see what results u get :)

Yes. Use the Touchwiz variant of the kernel.
[T-Mobile Samsung Galaxy S 4] kevinrubio1:
Are the people are running the latest version of this kernel running an international rom that's MF4+?

Or do you guys not use smart features?
[T-Mobile Samsung Galaxy S 4] elesbb:
Does anybody have a lot of random reboots? This is for touch wiz ROMs btw. I haven't seen anything so it must just be me which is actually good. I get about 2-5 a day both when using device and when not. If it's just me I'm gonna hard reset.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
No random reboots whatsoever so it may in fact just be you, least until someone else steps forward with the same problem but hopefully that doesn't happen..
[T-Mobile Samsung Galaxy S 4] trueking7:
I would recommend Omega v7 from the I9505 android dev forum. Use it with this kernel. I have a Canadian I337M and am running an I9505 rom with Ktoonsez TMO kernel.
[T-Mobile Samsung Galaxy S 4] Punchatron:
I had a couple of reboots today. My first. First one was this morning on 7/7 so I installed 7/11 but I got one about an hour after. :(
[T-Mobile Samsung Galaxy S 4] whytechapel_x:
If you really want to use all that then just switch to roms for the i9505, They're faster anyways.
[T-Mobile Samsung Galaxy S 4] trueking7:
Assuming you are using the recommended settings, try -25 volts instead of -50...

Sent from my Rogers Galaxy S4 (SGH-I337M) running Omega v7 with Ktoonsez TMO kernel...
[T-Mobile Samsung Galaxy S 4] omnifarious:
I had to disable force screen off on calls in order for the reboots to stop. All other settings are KTs

This was on an older version.

Side note, how do you get fast charge to stick? Using tmo kernel
[T-Mobile Samsung Galaxy S 4] ktoonsez:
It doesnt stick on reboots so I dont have to deal with 400 questions a day about why doesnt MTP work on this kernel.
[T-Mobile Samsung Galaxy S 4] elesbb:
Hmmm, I do get them on every kernel so it probably is me. I have so many mods and hacks for testing my next ROM release so it wouldn't surprise me. I'm gonna reflash my ROM and not mess with it lol. See how it does. Thanks!

the worst part is the last_kmsg doesn't have why. It just reboots.

Interesting. What ROM are you on?
[T-Mobile Samsung Galaxy S 4] Miami8906:
New aosp kernel is great no problems at all.
[T-Mobile Samsung Galaxy S 4] Punchatron:
Stock ROM with greenify running on a few apps and frozen bloat using titanium. I did notice tons of wakelocks from something called direct track that popedup after I installed poweramp. Just uninstalled and I'll see how it goes.
[T-Mobile Samsung Galaxy S 4] gaww:
I was running good with 7/2 on Omega 7, but on flashing 7/11 and touching nothing else, I immediately started not being able to wake the screen up whenever it timed out black.

Reflashed 7/2 and no problems. It looked like settings had carried over both ways, so didn't feel like chasing them around to try to fix it.
[T-Mobile Samsung Galaxy S 4] Punchatron:
I'm back to 7/2. Uninstalled poweramp. So far so good. If everything runs ok I'll go back on 7/11.
[T-Mobile Samsung Galaxy S 4] mike216:
I hate to beat this horse again, sorry

I'll just ask straight up. What's better for battery life. To have 1 set to sync extra cores and 1 set to touch boost cpu all cores?

I've done both by its hard to say. Just curious

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] ktoonsez:
The way you have it should save battery since ktoonservativeq will maintain a more even Mhz on ALL cores
[T-Mobile Samsung Galaxy S 4] mike216:
I have both set to 1 as stated in your personal settings thread. Thanks Kt.

I was sort of conflicted because it seems like it will use more power if more cores are running but it will finish the job faster. It's something I just can't test to confirm. I tried. It's not a big deal. I'm more interested in learning so I can move on to the next thing to learn. We all start somewhere ;)

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] ktoonsez:
That items name is a little confusing, it doesnt bring all cores on line, it only boost the Mhz on the ones you specify to come on on the touch_boost options at the very top. So no extra cores are coming online at all, just sync's the ones that are online :good:
[T-Mobile Samsung Galaxy S 4] mike216:
Gotta. So in my case or anyone using your settings cpu 2 will be the only one that has boost and your governor is taking care of it. Thanks again and have a good weekend

SGH-M919_Omega, the end result
[T-Mobile Samsung Galaxy S 4] Nexus85:
I have the exact same problem, random reboots about 2-5 when using or screen off. I just returned to stock....figured its because I flashed 6-10 for smart features then flashed 7-11 then back and forth again. I work for a phone carrier so I tend to flash a little more recklessly than most as phones are pretty much @ my disposal to replace. But yes even after setting kt's kernel to default voltages (which I usually have great performance from) phone still gave me issues running this specifc kernel.
[T-Mobile Samsung Galaxy S 4] elesbb:
My reboots were definitely not kernel related. Every kernel gave me reboots. I just wiped my data and flashed my ROM again and I went all night without a reboot. I'm very convinced the reboots were on my end. however with the latest kernel I did get that sleep of death where the screen won't wake up after deep sleep. Logcat told me that one of the devices under /dev was missing. When it happens again I will save the logcat and post it for ktoonsez. Other than that, with stock settings, my rebooting has seemed to stop. Will give it another day and then I'll restore my ktweaker settings.

I'm really hoping I fixed my rebooting. Ktoonsez does a hell of a job with his kernel. Thank you boss!

My reboots were also not kernel related. I was using greenify on Pandora and poweramp. Once I removed those apps I haven't had any problems. I'm on 7/2. I'll go back to 7/11 soon and report back.
