Screen freeze

Guys I need your help, when I'm using KT V6 MOD profile as happens a few things I really do not understand, when I put the phone to charge the screen is locked and no lights but the phone is on, when I hold the power for more than 10 seconds the phone resets. And if I have not used the phone for a long time (overnight for example) it crashes too. This is happening with Project Comatose - Rebirthing V3 also. Lost working hours because the apk alarm did not work because of it. Could you help me? My rom is Omega V33.

Try increasing the CPU volts in ktweaker. Also be sure to clear any CPU adjustment scripts found in "system/etc/init.d" folder. Use a file manager with root access to find the specified path.

If all else does not work then try reset ktweaker to defaulted settings and reboot. Apply new profile/script and reboot. Let the device sit a while. Hope this helps.
[T-Mobile Samsung Galaxy S 4] diacioli:
But how much do I need to increase? The only script that I found that change something on CPU was S92Omega, do you think that I need to delete it. Thanks for your help.
[T-Mobile Samsung Galaxy S 4] mamba720027:
Increase by 25mv and see how that works. Also increase the GPU by 25mv. And yes backup a copy of the script then delete.

Edit

Also be sure you're running the latest profiles. Some latest updated profiles posted an earlier time that is not in the ktweaker shop that you mentioned are in link below just incase.

I never could get my S4 fully 100% stable with any custom kernel... even with mostly defaults, after 4-5 days, sometimes after a week, sometimes few days, sometimes week and a half, device would lag, randomly reboot, random issues with screen on/off, stuttering audio playback, etc etc etc... eventually just got tired of pretending my device was stable, and tired of secretly hating my S4.... Been running GPE 4.4.3 with stock kernel for over two months now, not one single hiccup of any kind. 10000000% buttery smooth, reliable, STABLE. Past 2 months with GPE stock kernel has made me fall in love with my S4, no longer care for any of the bells and whistles a custom kernel brings. 110% stability is what mattered most to me, glad I gave myself the chance to run with it, in the past I wouldn't even run the stock kernel for one boot, it was flashed immediately when flashing the ROM. So to anyone else out there whose also pretending to have a stable device, but deep down you know it's not 10000% reliable and you couldn't trust it with your life, try stock kernel ;)

I manage a couple of M919 S4's for a few friends and cousins, and they all gave me crap about the occasional flakiness, to which I had no response. With my own device I'd always make some small tweaks, but with theirs it was kept exactly the same way the custom kernel came. Haven't heard any sort of *****ing from any of them in the past 2 months either.

I know a **** ton of work goes into the custom kernels, not hating on anyone or any kernel, maybe it was just my device (or all of ours), but I hated hating my S4, and telling everyone it was the greatest phone ever.
[T-Mobile Samsung Galaxy S 4] mamba720027:
That's good to know. After reading your story I think you unfortunately winded up with one of the very few S4 batch with a low rating in terms of manufacturers binning of chipset quality. That's the first taught that came to my mind.

For knowledge

en.m.wikipedia.org/wiki/Product_binning

This could explain the instability even with stock. If it was possible under warranty to swap for a new device from the beginning when you bought it that possibly would have solve it. I'm not 100% positive on this as i never had to but in theory a mild overvolting and underclocking may have help stabilize the board.
[T-Mobile Samsung Galaxy S 4] camry89:
Like I said, maybe it was just my device, but I also manage 4 other S4 M919's that belong to cousins and friends. By unanimous vote stock kernel is the most stable by far, and they know nothing at all about flashing or kernels -- only thing they know is original TW rom sucks, nothing beyond that. They don't even know what root is :)

Not sure if you read the entire post, there is no instability whatsoever with stock kernel, phones actions are predictable and reliable, every single time. No random flakiness. Even one screwup/random reboot/audio stutter/whatever issue, is one too many. With customs I'd frequently hear *****ing about audio stuttering when screen turned off. Or that phone was on but couldn't wake via power/home buttons. Or that it randomly restarted once earlier in the week (experienced this myself, even one is one too many). Have yet to hear a single complaint running the stock GE kernel. Can't speak for their devices as I'm not around them 24/7, but for me the difference in stability over the past 2 months is like night and day.
[T-Mobile Samsung Galaxy S 4] mamba720027:
That's your choice of preference from experience and nothing is wrong with that as with any dev work posted on XDA theirs always a disclaimer mostly stating that users flash or root or whatever their about to perform at their own risk etc. So if daily functions as you specifically mention in your second post is a concern theirs always help in the forums/threads. Plus users are free to return to 100% stock if unsatisfied. Just as you have mentioned based off your experience.

With that said a custom kernel 99% of the time would perform as stock but better as its frequently updated and pushes the potential of our device in one or more ways than other. Most of the time instability to functions as you mention would occur if the device does not accept the user self adjusted settings which can be readjusted to work. Also due to the variety of different variation of the S4 their is bound to be differences and hiccups along the way and that is why their are many settings gear towards the KT kernel available in this section. Not to get me wrong but from my experience using a custom kernel like in this section by KT works like stock just snappier and I like being able to bias between performance and battery.

The ability to tweak those aspects are phenomenal and I can't live without tweaking something even if I manage to break the device by trying lol. Stock is great but it takes away the reason why I stick with Android. But whatever works as not everyone likes tinkering and some just wants a device out of the box that just works cause that's why they spending so much money for it and so they never have to worry of fixing anything.
[T-Mobile Samsung Galaxy S 4] camry89:
That's the exact mindset I had also ^_^ I love to tweak. But for me the minimal (nominal) gains of performance/battery over the losses in certainty + stability nulled that. Besides, not like I need to do any sort of serious number crunching on a mobile device. If something takes an extra 1 second, literally extra 1 second to load, that's fine with me.

Custom rom with Xposed still gives more than enough options for tweaking :good:

The way I have my phone setup now with Unbounce and Greenify, seeing better results than even with a moderate undervolt (which remained stable just as long as non undervolt settings). When I was obsessed with running the custom kernel I was unwilling to accept it. If your phone is 1000000000000000% stable then I'm happy for you ;)

And like I said, I only made tweaks to my own devices and not the other 4. They got the "stock" settings of the custom kernel and still had random issues here and there.

Anyway, entire point of post was if there's anyone out there who NEEDS stability over everything else, and if you're secretly hating your S4 because of small bs hiccup issues, yes those performance/battery gains are pretty nominal, and not worth the trade off for ULTIMATE stability. Don't automatically dismiss the stock Google Play Edition kernel like I was doing. If your device is 10000% stable with custom kernel and NEVER hiccups, then disregard the last 3 posts :)

There's a good reason I waited 2 months before sharing any of this. Hopefully helps someone out there in the same boat I was in.

I really like ktoonsez kernel and the customability that comes with it through ktweaker.

ive downloaded many profiles and have used Asking Alexandria quite a bit 'as is'

however every other day or so I find going into ktweaker states that my selected values are not applied randomly. if I go into profiles, all the downloaded profiles plus backups have vanished.

so I re download and start again.

is it something I'm doing wrong or is it just the phone not handling the profile I'm using ?
[T-Mobile Samsung Galaxy S 4] mamba720027:
I have absolutely no idea why they are vanishing as it's first case I have came across in the thread.

If you are downloading the profiles from within Ktweaker then they all should be in the ktweaker folder under profiles I believe. Same thing if you're downloading them from here then you need to move them at the location of the Ktweaker folder and place them in designated folder for profiles.

If all that is checked and correct then it may be because of something you're doing.
[T-Mobile Samsung Galaxy S 4] robinta:
I've had this every time, with different varients of the kernel and on different roms. in the past I have applied a profile and then tweaked it..I.e. different uv or capping the max frequency at 1458 rather than 1890, but on my last go I just applied the profile as is.

its strange because everything goes from the ktweaker profiles folder, any profiles and backups. its weird.

I dont have any other kernel tweaking apps running, so cant see a conflict there.

Hi there guys i flashed the aosp 4.4 kitkat version on my i9505, after reading the last few pages im not sure if i should have? Im running cm11 m12 which is 4.4.4, and i read something about it having to have a snapdragon processor and i have no idea what processor is in my device. Since i flashed ktoonsez though my device has worked perfectly normal.
[T-Mobile Samsung Galaxy S 4] vadyr56:
So did we ever figure out what causes the media playback issues? I was never able to fix the issue, even after changing the 20 different things that were suggested. It'd be nice if it could be narrowed down to a specific parameter so I can change that in the profiles I use.

Also, any chance we can get some sort of repository going for all profiles in existence? Or close to it..seeing as the shop isn't updated with everything, which is fine. I'd be willing to help with either of these requests obviously. I'd really like to get the media thing figured out, I use my Bluetooth in the car for music constantly and the skipping is very annoying lol.

[T-Mobile Samsung Galaxy S 4] EuEra:
Actually i have noticed this when using the app audible to listen audio books (i havent tested out music yet) i have used a few different profiles now and all have the issue, even before i learned about profiles i changed 2 things myself with everything else on default i set the govorner to ktoonsconservative or whatever it is and the i/o governor to noop and even then it was glitchy audio.

---------- Post added at 04:27 PM ---------- Previous post was at 04:19 PM ----------

Also im using the dead by apri script and profile (both battery saving) is this the best option for pure battery conservation? i really dont care about performance the most i do on my phone is text and call i just want the battery to last as long as possible really without being too laggy but a bit of lag would be fine.
[T-Mobile Samsung Galaxy S 4] mamba720027:
I don't have my S4 anymore but if I remember correctly Ktoonservativeq governor has a parameter with something like " disable hotplugging on music playback" something along that line. What it does is have the 4 cores active using the cpu min frequency on screenoff while media playback is active. I recommend raising the min cpu frequency to the 400mhz range or higher to also help with your situation or look in Ktweaker settings for Bluetooth media playback and set the min cpu freq higher than whatever it is set too . Having the cpu sampling rate set in the 35000 range should be fine too and disable "superconservativeq" under Ktoonservativeq governor.

I'm not an underclocking guru by any stretch of the imagination, but it's my understanding that there's only so much you can do to reduce the power draw of the screen. No matter how hard you clamp down on the CPU voltage, it's still the same backlight and the same number of pixels.

Yes, it should be " boost_hold_cycles". Here's a few more you can set that should help with performance.

block_cycles_offline_screen_on = 22

[T-Mobile Samsung Galaxy S 4] EuEra:
OK so on all profiles i have used the auio playback is very glitchy, some worse than others. I'm guessing this is because when the screen is off the processor is limited to save power. Now i know there is a setting in KTweaker that you change from a 0 to a 1 and it completely elimantes the problem, i think this basically stops it from limiting the cpu when audio is playing. This however makes my battery drain how it always has, is there a way of fixing this while still make good battery gains.
[T-Mobile Samsung Galaxy S 4] LuigiBull23:
Maybe try locking 2 to 3 cores online when the screen is off and see if that helps.

I really feel like a dweeb

ok, I have the verizon s4 running Hyerdrive RLS19. I followed the steps that are listed here for first choosing a script (Balanced Bull Reloaded) . It came up green to show that it will load on the next boot. I then chose Balanced Bull Reloaded profile. Rebooted my phone and allowed it to charge to 100%. I am still getting crappy battery life. I do have Greenify on my phone and damn near everything is under "Hibernate".

What could be the culprit to the crappy battery life?

Thanks,

[T-Mobile Samsung Galaxy S 4] mamba720027:
Ok, I can't say 100% what is causing it but some of the things could be relating to the quality of chip in your device, some better than others meaning better heat management due to being able to handle Undervolting in that department.

Also a big factor would be apps consuming battery in the background unnecessary and the existence of long or frequent wakelocks. For this I recommend have a look with "betterbatterystats" . I'm using a module "Amplify" it takes care of all unnecessary wakelocks and turns off services that are safe to do so and help extend battery usage especially when not using the device. Also cuts the manual workarounds of guides posted allowing you to do the same thing with ease. Recommend getting the pro version.

Alas, to conserve that battery dispite my first paragraph. I recommend underclocking or find a profile thats underclocked the cpu like 3 bumps lower. If you not a powerhouse user then try profile "green" with script.
