Hello,

I am new to this thread and use generaly KT

I just installed this kernel on Phoenix v9. Good reponse so far fast and smoth, battery I still dont know but I will coment later this week.

I like the simplicity of the settings. 3 Profiles that can be modify. I use balanced, nightmare, uncheck gente _fair_sleepers, I am not sure about read-ahead and it looks to me 128kb and 256kb are too low but they are default so I will not change for now. I am tempted to go down in max freq to 1458000 to have better battery life but will wait and see during the next few days. No OC but I really think this is not necesary on the S4. I did not test sound and led yet. Charge is something I want to understand as since I am using Phoenix Rom charging is slow so maybe I can improve here but dont know the needed settings.

Thank you, great work!
[Galaxy S 4 i9505 Original Android Development] MohamedN:
Pressing any of those three profiles will make no difference for you at all. It's there so you can save your own tweaks at each one.

On kt kernel you must disable Auto_media_hotplug from 0 to 1. --> solved my stuttering with poweramp

I don't know about stuttering with this kernel cause i try it out first time
[Galaxy S 4 i9505 Original Android Development] davtse:
one of the solutions was to enable auto_hotplug instead of mpdecision for hotplug management
[Galaxy S 4 i9505 Original Android Development] ashramrak:
many thanks :good::good::good:

will try and report

Great Kernel [MENTION=1897326]googy_anas[/MENTION], I´m loving the performance and amanzing battery life!

I have one request though, and I think someone already asked you for it. Would it be possible to include a setting to increase vibration strenght? I feel Samsung´s range is way to weak and it can barely be felt even on strongest setting.

Thanks man! Keep up the excellent work with your kernel!
[Galaxy S 4 i9505 Original Android Development] qtwrk:
Raised up to 100% doesn't satisfy you?

Any higher value may damage your device...
[Galaxy S 4 i9505 Original Android Development] trein91:
Possible for you to port over ZzMoove governor from S3? That'll be awesome thanks. Wanting a no fuss hotplugging governor that stays mostly on 2 cores and ramps up to max and 4 cores on opening maps, browser etc and drops down again quickly.
[Galaxy S 4 i9505 Original Android Development] jgchaval:
I come from KT Kernel and I´m used to stronger vibration. I doubt it would damage it by just increasing it a small amount, since KT has had this setting increased by a very long time a none of his users never had any damage done to the device.

I have used it like that for nearly 1 year and my my device is phiscally OK. :)

Anyway, is just a suggestion...
[Galaxy S 4 i9505 Original Android Development] dr.wtf:
just to post a first impression, since nobody has done that yet:

everything works as it should :)
[Galaxy S 4 i9505 Original Android Development] strix75:
I tried that and it does not work for me.
[Galaxy S 4 i9505 Original Android Development] DaReDeViL:
Yes! I'll see if I can do anything about that ...
[Galaxy S 4 i9505 Original Android Development] DaReDeViL:
Does it cause any usage problem apart from "showing" 85% ram used ???
[Galaxy S 4 i9505 Original Android Development] dr.wtf:
question should be which app causes this... my ram is showing 0.97gb right now after using my phone the whole day...

OK, i've used v1.0.9 for a couple of weeks on Danvdh's GE ROM and I'm really satisfied. Fast and smooth, always stable :) I'm going to see now how new version works, then I will post my feedback completed with a couple of suggestions :)
[Galaxy S 4 i9505 Original Android Development] Edgio60:
Have you combined that with increasing the audio buffer size and/or thread priority within Poweramp settings?

Please add asop kernel and GPU CPU OC thanks
[Galaxy S 4 i9505 Original Android Development] Funky-kun:
New kernel version is pretty solid stuff. Around 10 hours of standby with location on (battery saving), 1:30 screen on time, and ~20 minutes of music - battery at 70%! No heating or stutter, everything works! :good:

I'm back on GPE and the kernel is working fine although today i was doing something i can't remember and i was gettin some constant vibrations i had to reboot but that solved it. Other than that all is fine. Cheers to you.

Im with viper and Danvdh rom, no problems yet.
[Galaxy S 4 i9505 Original Android Development] raksan:
Thank you very much, OP. I switch to Googy since 1.0.7 and it's pretty stable, I never enjoy GPE build until I have your kernel; phone run normal operating temperature (not warm) when normal use like web browsing, facebook... Now I'm on GPE 4.4.4 with Googy kernel 1.1 (using intellidemand as cpu governor), I get 4:23 minutes screen on time, which is fantastic for me.

I didn't use S-Tweak app because I don't like the way CPU/GPU control can be access from app drawer, and I want to try everything from stock kernel too. Yesterday I found a CPU settings that access from "Settings > Developer options", it intended to use on Nexus 5, but it also works on my current GPE build. So far, it's a perfect combo mod, I couldn't be happier.
[Galaxy S 4 i9505 Original Android Development] speedytr:
Great work mate! Much better battery consumption and much faster than Ktoonz. Core of your kernel is rock solid! (I've been testing for 3 weeks with Dans GPE)

Will you add more functionality and maybe a better tweaker interface?
[Galaxy S 4 i9505 Original Android Development] nick123ablxx32:
working fine on 4.4.4 just a random vibration when booting up (not a major problem....in fact I kinda like it :eek: ) overall smooth ,no overheats and no stuttering even with:

viper+Pon3 Audio Mod Build 5+ extreme beats studio mod :good: :highfive:

most notably battery life on GPE (default settings) is amazing especially on standby :D

thanks for the awesome kernel :o

[Galaxy S 4 i9505 Original Android Development] Bochdalek:
Hi,

I am on Danvdh's rom and I flashed this kernel because my SGS4 was overheating a lot.

I know the basics from rom/kernel flashing but thats just about it.

I flashed the kernel and cleared the cache, dalvik's cache.

But now I have the problem that my wifi won't work. It just keeps saying: enabling wifi but I never get a connection.

I never had this problem with the Ktoonz kernel...

Can somebody help me please ?

Kindest regards
[Galaxy S 4 i9505 Original Android Development] ne0__:
it looks like you flashed TW version, make sure you have GE version , reflash GE version..
[Galaxy S 4 i9505 Original Android Development] Bochdalek:
OMG so stupid of me. Thank you.
[Galaxy S 4 i9505 Original Android Development] OmniSlyfer:
Hi guys, it's time for my feedback :)

*/ Apologize me for my bad english

I'm rly satisfied of this kernel. Always stable and smooth, nice performances with darkness governor (can someone explain me how it's works? I see it works very nicely, but I don't know how lol) and fiops scheduler. However I would like to report a couple of bugs I've found:

1. When I receive multiple messages (normal, wa or Facebook) at the same times, the led goes crazy and it starts blinking extremely fast (in general it's a fast green blinking);

2. The interactive governor seems to be broken: it makes my device reboot during benchmarks like Antutu. Don't know why, but it happens only with this governor.

3. Really bad audio quality during calls. I've tried to reduce the preamp gain from 40 to 30 and the quality is acceptable now, but not like the one I got with alucard kernel.

Now I've got a couple of suggestions to make, that IMHO would make this kernel better:

1. A more aggressive/smarter thermal control. The temp reached while playing are much lower than stock kernel, and this is good. But I think it could be cooler with a more aggressive control (like Alucard intelli thermal control). Of course it will reduce performances, but it could save my hands after long sessions of gaming XD

2. Add the possibility to customize governors parameters, in order to achieve the best customization possible.

I'm running Dans GE, and wiped cache and dalvik after the kernel update to 1.1.0

I hope this feedback could help to improve this fantastic kernel. I rly think it's the best for GE :D
[Galaxy S 4 i9505 Original Android Development] dr.wtf:
i like the stockness of this kernel. it might be ok to include an option to tweak this stuff but please keep it stock.

this is only my opinion and subjective view: while much of ktoonsez code is even used in this kernel, he improved his kernel that much that he actually made it worse. lately i see a growing number of people saying that they went to other kernels after using kt for quite a time. so to avoid that happening to this kernel i'd really suggest to be cautious about new features.

for example i had the problem that kt introduced (or improved, i actually didn't quite get it) ipv6 support which is not a stock feature. this caused wakelocks in some wlans.

if you want extensive tweaking you can use kt kernel.

for the heat problem: try decreasing voltage

and i don't mean to step on anyones toes. especially not the ones of kt, since hes one of the most important devs for the s4
[Galaxy S 4 i9505 Original Android Development] slim80:
Hi [MENTION=1897326]googy_anas[/MENTION]. For my experience with Samsung S3, the best I/O scheduler in terms of performance and smoothness, while maintaining a moderate (not the best here) battery drain, is ROW. What do you think? Can you add it in the next update?

Thanks

:)

[Galaxy S 4 i9505 Original Android Development] DaReDeViL:
I already implemented row scheduler in a private test build and I can assure you that it also introduces some microlags which I didn't like, as you know that I'm very sensitive when it comes to smoothness ... So no row scheduler for now ;)
[Galaxy S 4 i9505 Original Android Development] 2ndammendment:
Smooth kernel although I do miss a few things though having switched from the KT kernel(was performing very poorly on my device recently)

Ability to lower min cpu frequency to 189mhz

DNIe options

Ability to undervolt less than 750mv

Screen off profile

Also the default headphone jack volume seems abnormally low.
[Galaxy S 4 i9505 Original Android Development] davtse:
we (the beta team) did a test with lower frequencies i.e 81,162 and 189. No real savings in battery life but there was a decrease in terms of smoothness. You can undervolt less than 750mv, you just have to use a different app to do so (i personally use android tuner).

as for DNIe and screen off profile, I leave it to googy to decide if he wants to implement it.
[Galaxy S 4 i9505 Original Android Development] synogy:
Not sure if this is a kennel or app issue but when I have the "cast screen" quick setting (see attached) the pull down menu stutters. I think it's because it's loading the quick seeing widget. But I can't see a way to turn it off. Any thoughts on a solution?

- think this is an stock android ROM issue as noted in the gravity box thread.
[Galaxy S 4 i9505 Original Android Development] nfsmw_gr:
Guys, I know that bfq scheduler may not be your cup of tea, but give it a go now that it's been updated.

No lags so far for me, smooth and solid performance.
[Galaxy S 4 i9505 Original Android Development] OmniSlyfer:
Well I also can't understand why everybody ignore the poor fiops scheduler... It works very fine for me, no micro lags and balanced performances...

---------- Post added at 08:38 AM ---------- Previous post was at 08:21 AM ----------

I've used KT kernel for a lot of time, but Googy is much better now ?.

However the couple of things I've suggested are nothing that can slow down this kernel. The thermal control is obviously implemented in every kernel, I would like to see a more aggressive one.

Also governors modding is already possible through other apps. The problem is that these apps don't always recognize correctly the governor, so some govs are fully moddable, others aren't.

So, as you can see, I'm not suggesting something new. Everything should also be activated at the discretion of the user. So those who want to keep the kernel as stock possible can do it [emoji4]
[Galaxy S 4 i9505 Original Android Development] nfsmw_gr:
Fiops is nice too, I agree.

Thermal controls would be a good feature to have, only thing I missed from the other kernels I used.

I used to mod my governors fairly well but now I have lost interest in doing so, used intellidemand as default for now and it's quite smooth I'd say.

Give it a go. :)
[Galaxy S 4 i9505 Original Android Development] -sandro-:
Is this on WiFi or data?

Anyway my phone gets hot on the top part of the screen (just under the speaker) only when using data I instead on WiFi it stays cool. I suppose it is how its supposed to work and there's nothing you can do about it.
[Galaxy S 4 i9505 Original Android Development] Shisma:

Now creating a flashable zip and flashing it, if everything's ok I'll post it in a couple of minutes. :)

[MENTION=1897326]googy_anas[/MENTION] check this please, if you like it you may use it as default from now on, it works exceptionally so far after one week of using stable settings. :)

Just flashed this kernel about 2 days ago and went to Toronto, thank you for this kernel! my stock kernel on my stock phone was heating up and going sluggish and so far i've been getting 1 day + half out of it on stock settings and its been keeping cool.

Thank you once again
[Galaxy S 4 i9505 Original Android Development] nfsmw_gr:
Well, I'm having some technical difficulties. :(

The script gets installed at init.d directory and will execute nicely using script manager, but the script will not work at boot, no idea why, the values remain the same. :/

Got any clue mate why might this be happening?

EDIT: I attached the .zip file.
[Galaxy S 4 i9505 Original Android Development] dr.wtf:
i'm reading through the documentation of the kernel at the moment and i dont like quite a few things in your script...

why would you set oom_kill_allocating_task to 1 if killing a rogue memory app would make more sense? also how often would that happen with a 2 gb ram phone so that it would make sense to save some calculation time while not solving the problem?

how good of a programmer are you to play around with the kernels multithreading abilities? asking because of the sem values

no need to play around with lmk since we have enough ram and i never saw a slowdown because of this on the s4

as swap is disabled in this kernel theres no point in changing that

overcommit_ratio is only important if overcommit_memory is set to 2...

do you actually know what you're doing?
[Galaxy S 4 i9505 Original Android Development] nfsmw_gr:
Well, oom_kill_allocating_task makes sense to me, but the recommended value is indeed 0.

It supposedly provides improved performance when set to 1 from what I've read.

You can modify it to your liking.

overcommit_memory and overcommit_ratio were in the script when using the version of the kernel which had zram, but will not affect anything right now, so it really doesn't matter if the modifications are in the script or not.

I am merely a programmer, the correct definiton for me would be "enthusiast".

But please don't judge without actually using this, for me these modifications made my phone smoother and way fewer apps are getting killed now, one of the reasons I made this is that even when having 2gb of ram my phone killed a lot of apps (using stock settings), and this achieved the effect desired.

Anyway, as I said I am not a programmer and I'm just trying my best to help myself and the community, if you don't agree with me or don't like these modificstions just don't use them.

It's that simple. :)
[Galaxy S 4 i9505 Original Android Development] dr.wtf:
well, i just asked. if you know less, then learn from what others write, if you know more then explain. thats how i think this should work...

how much ram is reserved using your script as far as your experience goes?

sorry, first question should be what rom you use to make it comparable...
