I'm currently unrooted. On stock 4.3 with MJ9 firmware.

I want to root and flash a kernel.

Should i bother about the firmware number being matched or not?
[Galaxy S 4 i9500 Original Android Development] tabenf:
Just flash this kernel through odin it root automatically numbers of firmware dont have to match
[Galaxy S 4 i9500 Original Android Development] Al Asmi:
I Flashed the kernel from last posts which is supposed to be V15 but after flashing kernel is showing alpha 14 in settings???

Using Logitech IEM UE9000 earphones, the volume is significantly louder than 4.2.2

This is a real problem because I need to turn the volume down so much it affects the sound quality. The most I can tolerate is volume level 5 with no EQ and 4 (!) with Adapt Sound on.

Why would this change so dramatically?
[Galaxy S 4 i9500 Original Android Development] Xphoid:
Tune your sound through EQ in Synapse app...

Samsung changed their impendance based volume compensation in 4.3. It should affect the stock kernels too.

Something is wrong though. Volume is so loud it distorts when I turn it down to a comfortable level.

At first I thought it was one song that was clipping (chick chick sound for a milisecond) but its happening on most songs. Volume 4 is almost as high as I can bare which seems to be affecting the quality.

I use my phone as my main source of music. Sound I go back to a 4.2 ROM/Kernal?
[Galaxy S 4 i9500 Original Android Development] cmd512:
No idea what you're talking about, Synapse is working perfectly fine here. If you reboot too quickly after accessing it OR clear the system cache, you will need to go into it on the first boot afterwards and click the "X" button to reset to your settings.

What issues are you having exactly?
[Galaxy S 4 i9500 Original Android Development] carlosm15:
works fine for me, no issues so far, i think you are the first person who say that, really..:eek:
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Then turn the volume down via the kernel controls? I don't see what the issue is. The impedance compensation change is in all 4.3 kernels and personally haven't had any major change for my headphones, but that differs on the resistance of the individual headphones.

I actually check the crash rate of the app and it's about 15 crashes per week for a userbase of around 2000 people, out of those 15 crashes most of it is coming from people and other devs playing around with the config / UCI while they're building their implementation.

Hi Andrei,

I've used your kernel before flawlessly, but today I flashed alpha v15 and my external sd card is not being recognized. I installed Adam kernel 3.5 and it started working again. I tested one more time with a new download and obtained the same results. I go to settings> storage and it shows me the option to install sd card, but after selecting it, a message saying my sd card is empty is displayed. I flashed the kernel using TWRP 2.6.3.1

I have a 32GB sandisk class 10 SD card. It is formatted as FAT32.

Thanks for your work mate.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I posted the SD card change a few days ago to test if people would have issues or not, I guess pre-release testing isn't popular...

It's only Class 10 cards which are failing?

Edit: Since I don't have any Class 10 handy and my UHS card has no issues, just tell my which of the following, in the posted order, work:

[Galaxy S 4 i9500 Original Android Development] mw86:
I like the pre releases, they are good way to debug early. The original two test builds my sd worked. But my external is formatted as ntfs and I had forgot that till recent. So I couldn't test Exfat function.

I was pleased to notice you stopped Samsung boost the cpu mhz boost found in benchmarks. Now entering one doesn't set cpu to 1200mhz or 1600mhz minimum.

I appreciate the preview. Your working wonders. On the first two pre release kernel I noticed a big boost I/o. I also noticed a much more enhanced governor behavior. Instead of dropping to idle mhz so easy its keeping in low to mid a7 mhz which seems to help prevent uneeded scaling jumps and I'm sort of thinking a helpful contributor to the better I/o handling. Im guessing there was more too it than just that. I hope what you had to change to fix ext sd card access wasn't what made that boost I felt.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
What I didn't want to hear.

If this one breaks it again, then we have a problem in terms of compatibility for the raised speeds on UHS.

https://www.dropbox.com/s/w1gzytmjpfo3in7/Perseus-alpha15-SDR25-4bit-noVol-160Mhz-i9500.tar

mw86, the issues have nothing to do with the filesystem but the frequency the cards are being run. I'll need to do some advanced debugging if the above breaks it again.
[Galaxy S 4 i9500 Original Android Development] kirabyte:
works perfect too ;)
[Galaxy S 4 i9500 Original Android Development] mw86:

I notice that I get more free RAM after flashing, used to have 5xxmB but now 8xxmB. This is not placebo.:good:

Will this latest version soft-brick the non-I users since they may not be able to see anything and the effect is controlled by the kernel?
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Ah crap. I messed up the files which I uploaded. That's an older version.

Placebo feedback.

Placebo. Yes it should cause problems for non-I users.

I re-uploaded what was supposed to be 0.1 as 0.2, really sorry for the mix-up here.

Happens to the best if us, don't sweat it.

The following is bench and temps :)

Pics hidden to save forum bandwidth

View attachment 1985589

From my observations I would like to point out even while throttling if the load just continues and continues you will easily see these temps too. 102c+

Also i included a stability test on 1200mhz max ie A7 cores. Results are little surprising. These A7 pushed up to 87c with ease over long term load. I wouldn't say the A7 is all that weak at full mhz as i think i still got nearly 24k+ antutu with just them, very formidable.

Thanks Andrei ill try your new version now.

Btw last version had amazing bench scores.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
1200 is still the A15 cores. 600 Mhz means real 1200 Mhz on the A7's.

Also, Samsung is quite of cheating on benchmarks since they're lowering the thermal throttling during benching. I should probably remove that.
[Galaxy S 4 i9500 Original Android Development] mw86:
Please do remove that buddy :) thank you for the info I had no idea. I thought it was 250-1200mhz a7 and 1300-1600mhz A15. Thank you so much such great info. It is greatly appreciated.

It would be awesome if the onky throttle was the main designed one. Thanks for being you :D

Or by samsung lowering throttle during bench do you mean as example 90c throttle but when benching it may be like 100c?

hello. This kernel has full support for 64GB micro SD formatted with exFAT?
[Galaxy S 4 i9500 Original Android Development] jlevy73:
You missed the point. It says 0.2 in the OP but after flashing, in the about section, the kernel is labeled as 0.1. He was asking for clarification as to whether the kernel should be named 0.1 or 0.2 since the info in the OP and the device are still conflicting.
[Galaxy S 4 i9500 Original Android Development] gun@id:

Andrei Lux would you consider adding the Frandom module Ryuinferno made easy to implement here with his github?

[Galaxy S 4 i9500 Original Android Development] sachinaik:
Guys,

Phone rebooted during Antutu stability test. Temp was hovering around 105 degree celcius.

I underclocked the cpu to 1GHz. When the clock is less I hope it will automatically apply less voltage.

I dont think anything, even dual video recording needs more than 1Ghz.

Two questions here :

1. What will be the speed of A7 cpu now?

2. Will it get confused because of 1GHz underclocking and always use A7 only (if the A7 clock is still 1200MHz)
[Galaxy S 4 i9500 Original Android Development] pewpew345:
Flashed it for the first time, ex-FAT is looking good and camera doesn't crash like it used to and I can set it to save photo to ext-SD (for now at least) but this mksh problem that I've gotten since flashing cofface's newest cwm still persisted. Anyone know how to solve this problem ? I've read that someone with AdAway experienced the same thing and it went off once he uninstalled it. Gonna be monitoring this whole night, hope it can run stable.
[Galaxy S 4 i9500 Original Android Development] mw86:
Maybe i understood Andrei wrong but seems to me yes A7 cpus support up to 1200mhz but this cpu doesn't use that range fully to stay efficient. Above he corrected my statement so it would seem 250-600mhz is A7's and A15 any mhz beyond that up to 1600mhz. If that is also not correct I need to go back to Exynos Octa school lol. Andrei may elaborate.

Btw Andrei your kernel update is running strong and trouble free.
[Galaxy S 4 i9500 Original Android Development] bala_gamer:
your phone is defective, i tried antutu with various clocks yesterday and im pretty sure that antutu runs fine below 80 to 85 with 1.4 ghz and yet scoring over 28k. lower the clocks lower the temperature. with 1.2 ghz the temp never went beyond 72 or something and still scored 24k.

q1: anything beyond 600 mhz is a15, so if you want to shut down a15 set your max cpu clock to 600 mhz.

all the clocks below 600 are running at 1:2 ratio. 600 mhz = 1200mhz a7.

15.1 working great here, thanks Andrei. I'm a bit curious about the ZRam update, would it have anything to do with the slowdowns on 14.1 I was noticing after extensive use?

(For example, I use Swype, and after a full day of use, it would start lagging badly. A reboot fixed that right up though.)
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Maybe but I can't say anything for sure. There was a bug but it shouldn't have mattered in slowdowns, never had them since 4.3 where zram swap was defaulted on. I've been running it for two weeks now as it is without anything noticeable.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Thanks, the entire system just seemed laggy by that point but that could be because you call on the input / keyboard everywhere. So, I'm definitely not ruling out ****ty coding on Swype's behalf.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Oh it's definitely coded by baboons. Gave up on Swype several months ago due to a bug in their cloud service that would wakelock the phone for hours, even if you disabled all the online crap, users reporting this for months, and them not acknowledging it.

Try TouchPal X.
[Galaxy S 4 i9500 Original Android Development] cmd512:
LOL, I do remember that actually, it would keep trying to Sync even when I set it to WIFI only or something along those lines, and drained my battery like crazy on a business trip. It would also keep erasing your learned words, which was extremely annoying.

It unfortunately is the only swiping keyboard I've tried so far that will do Chinese IME pinyin. TouchPal says it supports Chinese, I'll give it a go. Thanks!

UPDATE:

You weren't kidding Andrei, holy **** this keyboard is awesome. It's a million times faster, has full pinyin IME support, and zero lag when switching between languages. How is this thing free??
[Galaxy S 4 i9500 Original Android Development] captaineos:
Regarding the volume issue on 4.3 kernals - There is an option to reduce the headphone boost in Stweaks, however it makes no difference.

The volume for me is so loud it distorts the music even without EQ.

I rolled back to a 4.2.2 CWM backup and my music was beautiful again - acceptable volume level was 7 with no clipping sound. Back to 4.3 and volume level is 4 with some background noise and clipping.

Anything else I can try? WTF Samsung!
[Galaxy S 4 i9500 Original Android Development] mw86:
Are you reffering to the loudspeaker headphone eq?

Try setting the bass frequency and midrange one that are boosted over 0 gain to 0 gain on both and leave the other negative values if so.
[Galaxy S 4 i9500 Original Android Development] Anakha56:
Ummm STweaks or Synapse? Pretty sure changing STweaks values with Andrei's newest kernels won't have any effect...
[Galaxy S 4 i9500 Original Android Development] captaineos:
Perciveiring with testing has done nothing really.

-Open Synapse and scroll to Audio

-Lower the left and right headphone to 54db each, and press the Tick up the top

-Tick remains highlighted as if its stuck.

-Turn phone off and on again - casing it to crash on samsung logo.

-Fixes it self and boots, this time with NO audio or detection of headphones

-Power off and on again, open Synapse and try to reset back to default 64db

-Same problem

-Then reflashed Kernal in Odin and that fixed no audio problem

BUT we are back to extremely loud headphone output on my i9500. It's so loud I have to turn the volume way down which causes problems with the sound quality
[Galaxy S 4 i9500 Original Android Development] cmd512:

[Galaxy S 4 i9500 Original Android Development] mw86:
Thats normal 200mhz a7 in Synapse shows real mhz not like the other apps. So bbs showed 100 and 150mhz which actually is 200mhz a7 and 300mhz. This is because on all normal apps any a7 frequency are displayed at half the full clock. Is why if we have 1200mhz a7 max in synapse we see it hit 600mhz in like cool tool or bbs its 1200mhz a7. The a15 frequency are not like that and run exactly as they show.
[Galaxy S 4 i9500 Original Android Development] cmd512:
I was just reminded of this a few days ago: Little core frequency is shown as 2x actual. So, 200MHz min freq = 100MHz on the little cores, nothing wrong there.
[Galaxy S 4 i9500 Original Android Development] mw86:
Interesting I had not noticed that the other frequency missing there. This is very weird because after I have that echo command ran and its 2000mhz on that iks max frequency even though frequency table isnt showing those above 1600mhz on mine as well it then is scaling to the overclock frequency with this. I'm now surprised it is because while it is working right now for me I check the frequency table and it doesnt have anything over 1600mhz displayed atleast in the iks frequency table file. Perhaps the frequency table used is in an alternate location.
