Best kernel for i9500 from a brilliant programmer. Thanks Andrilux for the contribution.
[Galaxy S 4 General] MemAllocatoR:
this kernel is by far the best! great job AndreiLux!

one thing though, there is still some lag in window transition animations in whatsapp and other apps...

any idea whats causing it?
[Galaxy S 4 General] nagpalkapil:
Yes. Sokp for now. Link below

Requesting Andrei to work out something for WiFi hotspot to work again. Also the a15 cores are not showing up on many high use apps or games.. Just wondering if they're working. Any way to check?
[Galaxy S 4 General] zetlaw:
Ypu check with cool tool app. As for the a15 problem. Someone here said its related to odexed rom and i think he is right.
[Galaxy S 4 General] KnifeHead:
My s4 cant sleep at all :D

What did you mix with your kernel [MENTION=4167023]AndreiLux[/MENTION]? Redbull? :D

- no deepsleep, like always the culprit is h2blablabla....

- wifi tether broken, can turn it on but other device cant find it

- synapse fc if try to reset cpu governor section or try to reset globally

- no random reboot, yet :D

- A15 work good

Tested with my deodexed stock touchwiz xxufnc1 rom, with xxufnc1 modem, from clean installation.
[Galaxy S 4 General] aashuG:
Version 19 is working very good

No random reboots

Deep sleep is working good

But synapse is FC on global reset + on reset section under governer tab
[Galaxy S 4 General] Abschop:
With v19 my A7 cores are scaling unnecessarily to 1200/1300 MHz (depending upon the A7 max).

Most of the times directly from 200 to 1200/1300.

Checked nothing is running in background. Also already greenified all apps.

Plz help.
[Galaxy S 4 General] zetlaw:
I think its because of touch boot feature.
[Galaxy S 4 General] Abschop:
Touch boost as the name suggests should only boost the freq. When screen is touched. But it is scaling unnecessarily even if not.

Btw I tried changing the CPU boost freq.s in Touch boost but it still scales to 200 to 1200/1300 MHz.

---------- Post added at 12:26 PM ---------- Previous post was at 11:40 AM ----------

Scaling Periodically. :confused:
[Galaxy S 4 General] dr.ngk:
Yup boy just scaling periodically but it's scaling only the a7 . it's not using the a15 at all. Stock KitKat odexed v19
[Galaxy S 4 General] zetlaw:
Odexed rom has this kind of problem.
[Galaxy S 4 General] Abschop:
I am on Omega v20(Deodexed). And the A15 cores are working fine. As mentioned earlier, the problem i am facing is periodic scaling of A7 cores from it's minimum clock to Maximum clock. In my case 200-1300MHz. Which is actually 100-650Mhz.
[Galaxy S 4 General] AndreiLux:
That's normal behaviour of the scaling...
[Galaxy S 4 General] cmd512:
v19 working flawlessly even on my good old 4.3. It's just working so well, I'm not in any rush to get to 4.4.2 given there doesn't seem to be a reliable non-wipe upgrade method.
[Galaxy S 4 General] Abschop:
Oh! Then its all working normally. All thanks to you Andrei. V19 is quite a lot stable than v18. No FC's. No random reboots. No more horizontal black strips.:)
[Galaxy S 4 General] KnifeHead:
[MENTION=4167023]AndreiLux[/MENTION], would you like to make repacked perseus alpha 15.2 or 16.1 to compatible with touchwiz 4.4.2? pliz pliz plizzz... no other addition just compatibility with touchwiz 4.4.2, plizzzzz....

That version so smooth on 4.3 man...

19.1 is out (28th april) .flashed it.all cores working now..
[Galaxy S 4 General] ivanchin99:
I see Perseus 19.1 is out with no changelog.

One more thing, is it possible to make this kernel compatible with link2sd? :o

http://www.devasque.com/foldermount/kk-support.html
[Galaxy S 4 General] NEOAethyr:
v19.1 is probably the updated synapse.

I think I know what my crash prob is called, seems like it anyways..

Sleep of death.

The only thing I can think of is my internal sdcard is corrupted.

I also noticed philz touch recovery doesn't have a fix permissions option.

I've got both fsck and e2fsck on my phone.

There's no fstab though so I gotta learn howto use e2fsck.

At least I think this might be the prob I'm having.

I just don't know what cmd to run yet, it wants to know the storage mmc/mtd block name and stuff.

Edit:

I formatted, installed ttt nb3 with odin, installed latest philz recovery with odin, flashed latest persues with odin, and installed latest supersu with recovery.

Before installing supersu, right after flashing the kernel, I had graphical corruption when trying to boot recovery.

I don't know if that has anything todo with the kernel or not (if you flash a corrupt kernel I know you can still boot recovery).

I saw some green dots all over then the screen filled up with white horizontal lines.

Still had the sleep of death crash after installing the kernel, even after the formatting.

At least I got to see the new synapse, looked nice.

I'm recovering back to stock now :(.

Ohwell.

I recently Disabled the DVFS and im getting soo many random reboots. And why is Synapse force closing on reset Globally ?

Btw how to clean up/ reset all the kernel settings ?

After random reboot ,when u run synapse it resets to default setting just press ok :good:

Hope this works

Use v 19.1 it is very stable . Till now :o
[Galaxy S 4 General] HassanM:
Just flashed v19... Its running really nice (as usual) but I just noticed that this time around Synapse gives us the option of changing Scaling Governers... By default its set on OnDemand-Sec (as was in the past) but there are 2 more; Userspace & Performance

Can anyone plz shed some light on the other 2 in terms of performance/stability/battery/smoothness...

Thanks in advance....
[Galaxy S 4 General] aashuG:
As of performance governor it emphasis on power means runs cpu at max u have ultimate smoothness on the cost of battery life if u want to try ,try it while charging .

And of userspace as far as i know it allows the running program /app to control cpu frequency

Ondemand is best for gt9500 it create balance between performance and battery .:good:
[Galaxy S 4 General] deadirony:
Should I change QoS settings? Because my battery draining so fast. BTW I don't know what is QoS settings. Somebody can explain?
[Galaxy S 4 General] HassanM:
Just installed Synapse's latest version (.32) from Play Store... Right after that my phones behaving in a very weird way (Bootloops.... Getting stuck on booting.... ).... I have the same settings on Synapse as the last one (before the update to v.32)...

Weird!!!!

Can anyone plz help....

Thanks in advance. ...
[Galaxy S 4 General] NZnewbie:
Hi.. maybe if you are worried uninstall the latest playstore update in settings, more, application manager, downloaded... synapse.
[Galaxy S 4 General] cmd512:
I am having zero issues on the latest Synapse with 19.1.
[Galaxy S 4 General] aashuG:
U can uninstall the latest update check the problem still exists or not

I also updated to latest synapse i do not hav such problem

[Galaxy S 4 General] dr.ngk:
After using my phone for few days I noticed again that a 15 cores only show up in the first moments after boot. And the voltages of the lite cores are higher than the a15 cores for the same frequency. But on any activity the phone jumps to the highest a7 frequency . for eg if I keep little core Max freq 1500 it shows a7 1500.

N the voltages from 200 to 800 are the same. But at the same time much higher than a15 s.

I also noticed when toggling the CPU Max freq. It starts from 200 upto 1500 after 1500 increasing it puts the NUM 800 1000 n so on till 2000.

Whatever I do, I get a battery lasting y hrs Max. With 1 or 2 hrs screen on time. I could help by giving a log whether a battery log or whichever will be most helpful to Andrei if he tells me how to get the log. Would be happy to help. I'm using stock 4.4.2. Xxufnc1 which I rooted by flashing Perseus 18. Also on boot when a15 ate in use the CPU rev shows v3. When à15 shut down it changes to rev 2
[Galaxy S 4 General] dannyb0i:
- and your point is...? A7's higher voltage doesn't translate into higher power use since it's way smaller than A15

- that's called scaling - nothing wrong there.

- so?? Clearly dropping below that decreased stability etc hence that's the minimum it's running at, and again higher voltage doesn't mean it's more power hungry
[Galaxy S 4 General] dr.ngk:
See dude, I'm not in this field, so I'd rather not open my mouth n sound silly to y'all. But my whole point is that my phone s battery life has drastically gone down. M neither is there any jump in performance. I just tried to post whatever I noticed. Glad u answered my queries but bottom line is I don't see any improvents. Going back to stock...in fact thinking of changing my phone as well... Neither is my Wii fi hotspot working

Are you noticing any battery drain due this GPU over clocking....
[Galaxy S 4 General] bala_gamer:
cpu settings in stweaks wont reflect on any other cpu tuning apps, either use stweaks or 3rd party cpu app when it comes to cpu, not both :) btw android tuner pro is one of the best all in one tools, try using it instead of sytem tuner ( both from same app dev)

---------- Post added at 11:07 AM ---------- Previous post was at 10:59 AM ----------

@ andreilux and others

eventhough the gpu clk is shown as 640mhz i dont see any visible in fps egypt 2.5 hd or epic citadel, is it just me or the clocks not being applied?

eg :

i get 42 fps in egypt 2.5 hd onscreen with stock gpu speed and @ 640 mhz

epic sitadel at extreme settings gives an avg of 45 fps both with stock clock and @ 640 mhz

edit:

im using cool tool to monitor gpu clocks.

will make an application similar to mali status to monitor gpu parameters, thanks [MENTION=4167023]AndreiLux[/MENTION] for posting the details .

edit 2:

700 mhz is not stable, it boots but crashes when used in any app, may be +25mv or +50mv might do the trick if there is still some head room on voltage part without damaging the internals
[Galaxy S 4 General] bala_gamer:

[Galaxy S 4 General] skivnit:
Is the camera fixed now with latest mf8?or do I still need to flash the separate zip
[Galaxy S 4 General] Xphoid:
I use latest Indian MF8 base and directly flashed Perseus alpha 4....

no camera problems at all!!!

:victory::victory::victory:
[Galaxy S 4 General] vin_eme:
can you share the 2 files..which was part of MF8. I backed up only the MEA camera files.

thanks...
[Galaxy S 4 General] bala_gamer:
the fix is already available as flashable zip in the kernel download page
[Galaxy S 4 General] vin_eme:
Well these are MEA minus fix files. Which are old prior fix to make the camera working. After Alpha 4 we can use the latest MF5 or MF8 camera files. I unfortunately didnt take a back up of the same.

Also i dont have the CWM installed....so i just use odin to flash the kernel :(
[Galaxy S 4 General] giangishanghai:
camera fix removed

hi man,

i am running MDE rom and with alpha4 camera crash.

trying to download fix files but the link it appear to be removed

cheers
[Galaxy S 4 General] kondronaute:
i have pbm with camera and not find the patch file on dropbox (removed)

i return to stock KERNEL-SER-I9500XXUBMF8 :(

a solution please ?

you can use Alpha 3.4 . camera is working for me with MDE rom.

[Galaxy S 4 General] jlevy73:
[MENTION=228377]Bala[/MENTION]: I haven't had enough time to play around with the GPU clock setting yet, just enough to set it at 600mhz and walk out the door. I did run GFX during a break and saw an increase to 46fps in Egypt 2.5 but that was off-screen (got 42fps on-screen). I will play around with it more little later tonight and report back.
[Galaxy S 4 General] Paolonicus:
I noticed something when I played with the settings with the Audio Control on STweaks. There is a hissing sound, and if I enable Headphone Equalizer, it becomes even more audible. Currently applied Eargasm setup on the EQ, and will probably try Pleasant for Ears setup later.

Anything that you would recommend in reducing, if not removing that Hiss sound?￼

Many Thanks!
[Galaxy S 4 General] kondronaute:
i have the pbm with this one :(

---------- Post added at 03:11 PM ---------- Previous post was at 02:38 PM ----------

i download again the kernel and now it's ok :)

[Galaxy S 4 General] jlevy73:
What happens when you try using stock or Adam kernel, do you get the same hissing? I wonder if your issue is a hardware one. I have tried to reproduce this but have not had an luck.
[Galaxy S 4 General] mazbot:
Why others kernel's developers are so "proud" to announce that they updated linux X version to Y version in their kernels?

Does AndreiLux also do this without mention it everytime?
[Galaxy S 4 General] mw86:
Last i knew eargasm settings poated i thread were for wrong kernel and not transferable. The final audio revision Andrei made uses different values now on the frequency ranges per eq adjustment.

Default value is what is set by kernel by default. And frequency range noted.

I tried using Perseus before, then now Adam Kernel 1.4. And yep, both have this hissing sound during playback. I played with the settings, but still didn't help.

If hardware is the case, then perhaps my Audio Chip is faulty?
[Galaxy S 4 General] Xphoid:
did anybody noticed, on antutu score results page whatever the setted CPU clock it shows 2000MHz(x4)... actually mine is 1,7...

and whatever i do, GPU doesnt make any difference in benchmarks as if it has no effect like [MENTION=3877923]bala_gamer[/MENTION] mentioned earlier...

i OC'd to 700 and UVd -100 almost on all freqs and -50 on top 3 freqs... no reboot no SOD nothing... do i have the super capable S4 or what? :)
[Galaxy S 4 General] hotheabilly:
Oc'ing my gpu to 640mhz and I can get 9000++ of 3d scores from antutu
[Galaxy S 4 General] Hakosuka11:

[Galaxy S 4 General] aashuG:
My way 2 check a15 is

Just open synapse on main screen

Then lock the phone and unlock it menu key u will see a15 trigger asap the phone unlocks :D
[Galaxy S 4 General] HassanM:
I did as advised.... Just noticed that A15 kicked in but for just a sec and then went back to A7.... Is it normal????
[Galaxy S 4 General] aashuG:
Yes it is normal

Why a15 will remain trigger unnecessarily without using any heavy app that is why it returns to normal this ur phone is working fine

Ifu r phone not working fine on unlock it shows a7 at max frequency

hey guys i am new to rooting and i am using stock 4.4.2 rooted with philz recovery... can i install this kernel on stock rom and can you tell me how to configure this kernel for best battery and performance? i just have to put in odin in pda and install it?
[Galaxy S 4 General] HassanM:
Yes!!! U can.... Just download the zip file Alpha 19.1 and simply flash it thru Philz recovery.... As for the configuration, download "Synapse" from Play Store.... This is custom designed App by Andrei for Perseus... Once u install Synapse, give it SU access and u should be all set... Tweak the kernel as u please.....

Good luck!!!

[Galaxy S 4 General] stevae:
how does "Synapse" compare to stweaks? i use to use perseus for a long time, but i thought he stopped dev on it, so i switched a while back to adam kernel. now i am on omega v20, and using maxfour kernel. has anyone on here used maxfour? i'm just wondering how the two compare now days, and thinking about switching back to perseus.
[Galaxy S 4 General] HassanM:
Firstly, STweaks was developed by Gokhan Moral (developer of Siyah Kernel ) and Synapse on the other hand has been developed by Andrei (Perseus)....

In other words Synapse is more Taylor Made or rather soley developed for Perseus making it a better kernel tweaking tool....

As for the Kernel, I believe nothing beats Perseus. .. Its strong, robust, very responsive and very smooth... Ive tried all that uve mentioned but nothing beats Perseus....

At the end of the day, its a matter of personal preference.... Mine is Perseus all the way....
[Galaxy S 4 General] AndreiLux:
Synapse is the successor to ExTweaks/STweaks and fixes their design problems and issues that Gökhan never got to.

And no it isn't tailored to any kernel. There's twice as many users on other devices than on the S4. On the Nexus 4 they did some really good stuff with it.
[Galaxy S 4 General] HassanM:
Thanks for the info Andrei.... By the way is there any update coming for S4 after Alpha 19.1???
[Galaxy S 4 General] stevae:
thank you for clearing that up. maxfour runs my s4 very nicely, and it is smooth. but the benchmarks are extremely low, thus the performance is not good. so i will come back to perseus, and try synapse.
[Galaxy S 4 General] stevae:
ok, i have perseus back up and running, as well as synapse. are their profiles we can download, where the processor has been overclocked, and voltages applied accordingly? for those of us who are not as savy with this hardware as others, it is a little bit scary to mess around with it. if others, who are more in the know, have experimented with it, and found good solid setups to increase performance, without making it unstable, or absolutely killing the battery longevity, that would be very helpful. thanks to anyone who offers any help with this.
[Galaxy S 4 General] quincho54:
I run on maxFour with wanam 442 and it's breathtaking. First day shecked the power, so far pre good. Still some more testing to do. What I had to do was, settings in developeroption, animationsize 1.5 as well the other two. On 1 some of the apk's lik repix couldn't with the speed.
[Galaxy S 4 General] ice.modding:
It happens when I install the kernel enters Deepsleep perseus, BUT after using it a while, no more reenters deep sleep, and the A15 does not work. Any method that has worked for them to fix this?
[Galaxy S 4 General] zetlaw:
Deodexed rom.

And cleaer cache
[Galaxy S 4 General] ice.modding:
i tried with that, but don't work. Other idea? :P
[Galaxy S 4 General] zetlaw:
Maybe bootloader. What bootloader do you have ? I was having same issues like you and mpved back to 4.3 rom with perseus. Everything works great no wifi tether bug.
[Galaxy S 4 General] NonXtreme:
Try other deodexed rom. I used to have this problem on hassan rom and try everything with no luck but then I change rom to Ozcanrom and problem solved.

Ozcanrom 2.7 with Comadose 3.5

Perseus 19.1 with old bootloader.
[Galaxy S 4 General] sak500:
I had no deep sleep issues on every 4.4 ROm with perseus except OCZRom. The culprit according to BBS was some l2_Hsic wakelock never letting the phone into deep sleep. So if you want to use perseus on 4.4 roms try it OCZ. It's pretty good rom. My current daily driver.
[Galaxy S 4 General] ice.modding:
I do not like that rom. I'm on a deodex firmware. I'm with the last firmware bootloader FNC1
[Galaxy S 4 General] NEOAethyr:
Tried 2 diff sets of deodex script things, both required java.

I hate java, it installed, but doesn't run, hasn't for over 15 years or so lol (spyware pos...).

Is there an alternative?

Right now as is I have to restore my phone to stock to charge the battery.

I'm about ready to try another kernel to see if it has the same prob as perseus.

Hmm there isn't any other kernel's unless I wanna dl an entier rom like omega's :\.

What the frik...

Ok what I did was restore to 4.3, and install adam kernel, same crash.

Went back to 4.2.2, installed perseus v12.2, crashed at the kernel boot logo.

Pulled battery, started back up without usb plugged in, started up fine.

Plugged in usb, says it's charging, powered off, crash...

What ticks me off is I had 4.2.2 and 4.3 working with perseus before I flashed 4.4.2 and now I can't use a custom kernel, only the stock one works.

My phone has been a useless paperweight for months.
