so regarding the audio issue, i tried last kernel/app version and put the audio cpu value all the way up to 1700ish. Sometimes it works, sometimes it doesn't, but overall it seems better. I also noticed that sound gets distorted sometimes when adding too many effects, that might have to do with processing power as well? what happened to the idea of moving audio processing to the big cpu?

yesterday i posted a message on how to reproduce the issues, today i can't see it, not sure if it's some bug from xda...excuse me also for being slow and not following all the messages here, sometimes the xda app doesn't notify me of posts here.
[Samsung Galaxy S8 & S8+ Cross Device Development] wingzki:
i just rename the latest twrp version. 3.6.x something
[Samsung Galaxy S8 & S8+ Cross Device Development] PIKO!!!:
Don't use 3.6.x. It was giving me a bootloop. Use the one in the first page of the thread.
[Samsung Galaxy S8 & S8+ Cross Device Development] Dexster909:
Hi guys. I've been using your kernel for about 1-2 months now, and now I've created an account on xda. Developer, can you help me, some games won't start for me. name: standoff 2

I think it's because of the RAM. I'm fine with my phone.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Won't start like what?
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
hi, sorry for posting it in the wrong place.

so, viper4android and jamesdsp use convolution technology for audio processing. jamesdsp just gives better/clearer results than viper, but something about that makes it use more processing power. as far as i understand it these use a lot more processing power also then the stuff that comes with samsung like uhq upscaler etc., and it was confirmed when i could finally get this adb code to read my phone activity (somehow my phone keeps disconnecting from my mac).

I could replicate the issue with sound scratching while watching audioserver load go all the way up to 90ish%. this was done with little cpu and audio cpu at @1794, which is the maximum i could get stable on my phone. but i did try before with @2002 and i could still get the glitches in sound processing.

when i use a more moderate approach to sound processing i cant get more conservative numbers around 50-60%.

what worked for me in another kernel i tested though, was to use performance governor for little cpu. though i could not push the audio processing too far, i could do more than i can now. i read that audio processing was moved to userspace governor, so i wonder if another change in that area would be interesting.

i understand moving audio processing to big cpu would be very battery intensive "just" to play music, but we are talking convolution processing of highres audio files. i guess it would be analog to playing heavy games like some of the guys here do :)

so i don't know, perhaps an option to toggle that on/off at user discretion? different governors or switch between big/little cpu to play audio?

i also understand that what i'm doing is very specific application of this trusted old phone so i understand if this is just going too far...
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
That is not how it works
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Standoff 2 can run on toasters. There has to be another reason.
[Samsung Galaxy S8 & S8+ Cross Device Development] Dexster909:
idk. I have a black screen on startup. Try to run someone. I have many games and standoff 2 it runs on ultras. And on your core 0
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hmm I don't think it's any kernel issue. Also I doubt it's related to too low RAM. This kernel has the biggest amount of RAM for the S8 exynos series. So probably it's a bug with the game itself. Maybe Android 9 not fully compatible for that game. Or maybe not compatible with the ROM ? Have no idea what ever custom ROM you use and what ever mods you did on ROM side. Good luck.

@madhatter57

Alright, I'll see what I can do for next release. Thanks for your inputs.
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
thanks brother, if you need any testing, let me know.
[Samsung Galaxy S8 & S8+ Cross Device Development] Pistero07:
Hi all, after playing with benchmarks on samsung dex and max cpu, gpu frequency (perfectly stable) I got these results. you made it like, you're the best. Thank you for your dedication and all the time you dedicated to the project. This is pink perfection!
[Samsung Galaxy S8 & S8+ Cross Device Development] Dexster909:
I used 2 ROMs, it was a regular android 9 stock. And horizon ROM please help. It works for me with a regular kernel, but yours will be better
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
Hi @ace2nutzer

just wanna thank you for all your work (and active contributors of course) and let you know that i'm realllllllly late for joining the party, i started using your kernel since 20220624 version and right now i'm enjoying the 20220701 version in combine with the latest stock rom i had from OTA. Never really thought i would need root or even change the recovery/kernel coz the stock rom and kernel was already good as it is.

Originally, my motivation to jump aboard was the dex and drivedroid support.. but now i got the UV tuning madness coming back to me, still trying hard not to tweak performance settings til i'm sure my applications works without issue

there are 2 questions tho :

- drivedroid works but still can't figure out to working dex on my non-smart tv, is there a specific setting i need to switch before it could be activated?

- ANYBODY here use filmorago? mine used to work with no issue on stock kernel, but now it hangs on the splash screen but never enters ANR or crash. logcat shows nothing weird except for EGLint returns 0x3000 (tried clearing data, corpses/remnants, uninstall-installing, enabled all permissions for that darned app to no avail)

any solutions / recommendations appreciated.

TIA
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
For dex you need charger to active the dex i don't know that can happen with this maybe dev know where the issue is,

On stock kernel dex can active
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I have test it and stuck at splash screen
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Ok but don't expect that i'll fix that.

This phone is now old. Support and development is now lowered.

Also there will be no custom ROM from my side. Also I'll not add support for higher Android versions. But i'll try to keep this kernel alive by fixing critical bugs or critical security leaks. I'm working on a new Android app.

Also this is likely the last custom kernel / app project from me. If someone want to know why, just ask.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i actually have an official dex hdmi cable and from what i have tested it certainly doesn't activate on any tv/screens i own.. i haven't invested more time researching this tho..

thank you very much for your time testing this out.. glad to know that the issue isn't in my end..
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
maybe the cable or something i have problem about cable that broke inside
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
nvm, it works.. not with the official hdmi cable tho

i got myself a 10 bucks worth hdmi and usb c (PD) adapter, it just automagically worked lolololol

now that is sorted out i only need to figure out why filmora stucks on this kernel 😂
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
wow 10 bucks whats brand?
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
seriously i can't tell.. it's made in china, doesnt have any brand labels and the manual does not represent the actual physical device.. i left the box at the office, will post some info later
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
or you can photo the product ?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Ace it's best you don't do Custom ROMs or higher android versions support. IMO higher Android versions custom ROMs are very pointless if updated over the "sweet spot" point for the hardware. The more you update the OS, the slower it becomes, it's inevitable. Android versions become heavier and meant for more powerful hardware.

It's a shame that you won't be making anything new though. But it's a choice to be respected. You carried S8 development for the last 4 years, so.
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Quick question, is reboot alwaus necessary for "Little only" option to work or just toggling it on/off is enough?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah thanks. It's a problem with time and money. I've calculated how much money the app should cost for just covering the costs I need for a month.

That must be 100 € for every app as an minimum to just survive the month like a poor guy. So I even don't think to try it at all, because likely nobody is willing here to pay 100 € for a better kernel and manager app. This is calculated according to the data provided by Google Play. The problem is that not enough S8 users did actually a purchase. So that's about the amount of sells. If much more users would by the app then it's of course possible to provide the app for just 1 € reaching the same result.

But the new app will cost 1 € and you will be able to use it on every rooted Android device.

Also I would like to fix random reboots for my Philips 3D smart TV.

Yeah that company literally stopped firmware updates without to fix random reboots. It's not possible to watch a film without to face a reboot.

I'm not sure if it's powered by the Linux kernel, if so maybe I can help.

I think a lot of people who have this TV would be happy.

If reboot is required the app would tell you. So not needed.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I see. That is a really tough situation. I really hope that you can somehow find a way to increase your income very soon mate. You do not deserve a struggle like that. Probably the new app can turn out to be a solid source of income. Root users in general are much more frequent than S8 root users. A vastly bigger userbase, so. As always with developments from you, I'll buy it and use it on my other devices, so in my little lane I do help.

Also I hope that TV has a Linux Kernel :ROFLMAO:

TV firmwares are usually STRONGLY neglected. So people have to take matters on their own hands.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
there's no label, no text and no standards/regulation signs anywhere on this thing haha
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
TechNoob well said.

i've bought your app since my first day using this kernel to support all of your hard work and definitely would do it again if i can.

I understand your concerns and knows exactly that sooner or later our device will be just another thing in the past, i've been there many times.

I can only wish you luck on your projects, and may they'll be your stable source of income, but whatever you're doing i hope it's in line with your passions.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Old or not, he made this S8 feel always new. Unironically S10 level of snappiness. A 5 years old device, yet its design still feels so modern. And with Ace's Kernel, it performs like a modern flagship without the 120hz screen. He did WONDERS for this device.

One could only IMAGINE what this man could've done given enough time, money, willpower, patience and energy, not only to the S8, but to other devices too.

I am not being unrealistic or exaggerating Ace's feats. It's just that this fella left a mark in S8 development.

In Summary:

He introduced Battery Idle and the possibility to charge at a faster rate

He gave us voltage control for the first time on S8/S8+/Note8, and for EVERYTHING IN THE SYSTEM

He increased available RAM

He unlocked GPU frequencies above that damned 572MHz

He allowed flashlight intensity tuning

He made frequencies above 2496MHz for Big Cores stable for the first time and he also achieved 2002MHz stable on the little cores

He wrote HIS OWN DVFS FROM SCRATCH AND TOTALLY DITCHED SAMSUNG'S MESS

He added some gamepad drivers (I don't use them, but that's a nice extra)

He made HIS OWN KERNEL MANAGER APP

Offers a SafetyNet Bypass

He allows to go for a Little Core only mode to save a LOT of power

He gives US the control for temperature up to 100°C. That is literally as much headroom as he can possibly reasonably give.

He introduced STABLE ZRAM

He offered us default performance profiles to quickly tune the device according to what it will have to go through the day

He's been CONSISTENT for 4 YEARS STRAIGHT WITH HIS UPDATES. And he STILL SUPPORTS THE ACE 2 TO THIS DAY

Even on stock frequencies, his Kernel makes the S8 smoother than a damn stock Exynos S10. UNIRONICALLY.

And more, but these are the most important ones to my eyes. And all of this world of tweaks is available for us to tune to our own preferences

for 1 damned buck. 1. It's all this man asks. I'd personally pay even 20 for this, since I no longer see this as a Custom Kernel but more like an entire revamp of the device. After all, it's not like we didn't spend hundreds to get this device in the first place.

Ace is a dude I would actually give 20 bucks to and trust whole heartedly that he would be able to make something amazing with the skills that he developed over the years. I know many people would prefer a much lower price, but I'm just saying what I'd be willing to pay.

Also he supported my totally mental obsession with benchmarking. That to me is already +10 points to gryffindor on its own

So this is my point of view, to be honest.

I have a question though, Ace. Other than occasional bug fixes if something ever comes up, is this Kernel technically finished? In the past you stated that your main objective was to make it stable. It is now. It doesn't reboot anymore and the missing features were added. The world can end, it won't reboot, lmao. Has the completion been reached?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
ouh iknow this product that cheap i was tought that have 2x usb 3.0 hahaha okey bro thx for the pict
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@TechNoobForSale

Thank you as well for spending your time on listing the most important features we developed here.

Actually I can say yes this kernel is fully optimized and complete. Of course some minor bugs may be still there like audio issues if you add too much filters, but I think that'll be fixed in next build.

Other than that you may can expect some improvements in A2N app.

I want to make the performance profiles more useful and user-friendly.

I.e. changing things like up_threshold and CPU boost and maybe even temperature, input booster settings according to the profile instead of changing only CPU/GPU Freqs.

But my next toy would be that new app and hopefully some development for my 3D TV. I did some research and it looks like it's running the Linux kernel. For now that's all, but who knows, as long as i'm alive maybe I could start some new project. So I'm not saying that I'll newer build a custom kernel again. I did that for years because I did really liked it, but now somehow it became a bit annoying and boring to me. Because if I start to build kernel for e.g. S21 then it's more or less the same. All the features and improvements can be applied with small changes to almost every modern Android phone, especially from Samsung.

It's 1x USB 3.0 or not ? Due to the blue color. But you can add a cheap USB hub with lots of USB ports lol.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
yup that can use usb hub but i was think about faster transfer hehe
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
hmmm if you bored maybe you can make youtube channel maybe can make more income for you
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Hmmm but then if especially for Samsung phones, everything is more or less of the same, then does that mean that development times would be noticeably shortened for new custom Kernel or apps?

If that is the case then, you’d be able to get income from the users of other Samsung devices forums as well in a moderate amount of time. Though it’s sad to see that it was a passion for you and now it became boring. Maybe it’s new challenges you’re looking for? (Gotta do the double game somehow. Income while following your passion for Kernel development. You know what they say Ace. Find a job that you really like, and you’ll never work a day in your life).
[Samsung Galaxy S8 & S8+ Cross Device Development] Arnz09:
Is this normal? Everytime I update I need to restart several times to fully optimize all the app. Like when you boot up your phone this "phone is starting optimising app 1-317 app" thing pops up right? I need to restart several times until that thing doesn't pop up like a normal boot.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Nope, you should see this only after wiping dalvik-cache. So i guess there is something wrong with your /data partition. I suggest to format it. Do a twrp backup of /data before, format, reboot to twrp and restore the data backup. If it doesn't solve the issue you need to do again the same but without backup and restore, means you need to configure your phone from scratch. Good luck!
[Samsung Galaxy S8 & S8+ Cross Device Development] Arnz09:
Is there no other way to fix this? Like without formatting the data.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
that just only one way because your /data get corrupted or some broken app trigger the pop up
[Samsung Galaxy S8 & S8+ Cross Device Development] Arnz09:
Well I don't feel formatting my phone. I guess I'll stick with restarting my phone several times. It gets fixed in the end.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Did you already tried this method:

Twrp backup of /data

Wipe /data with the "yes" method..

Reboot to twrp and restore the /data backup.

This should usually fix filesystem errors.
[Samsung Galaxy S8 & S8+ Cross Device Development] Dexster909:
Author, I think that applications do not start due to zswipe this does not allow the game to start normally, or because zRAM
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Its weird, i got one too but somehow i cant charge while using it, also i got issues with my s21 and a usb headphone and a usb c charge splitter, charge so slow lol, but atleast i dont drain my phone while watching something lol.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
same me to i have 10 bucks adapter but that charge slow when using original AFC but when i use xiaomi fast charger that have qualcomm fast charge 3.0 that goes WIIIIIIIIIIIIIII 3.3 A at 9 v
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
idk for sure since the device vendor could be different.

but before making the purchase i made sure that the USB C on that device is USB-PD type.. that might be the issue

but if it's really USB-PD type then the problem might be caused by the charge splitter or cables, it needs to deliver 1500mA at minimum to charge quickly
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
This kernel supports also quick chargers 2.0 and 3.0.

WTH is zswipe ? zRam can be disabled in a2n app. Or try with swappiness 100, maybe better.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Hmm, ill try both options when i find them. But guess an other usb c splitter wouldnt make a difference becus i tried 2 different ones, so guess ill try the charger suggestion, but about the usb c hdmi adapter i should look for another one becus that one sucks
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i think he meant zswap
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
This was the first thing I had removed on this kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
So I finally got more accurate results in, and even calculated some PC GPU comparisons about the levels of performance this Kernel got us.

First and foremost, yes. At 764MHz and 839MHz we are faster than the Mali G72 MP18 at 572MHz by respectively **30** and **40%** in more accurate workloads (GFXBench Aztec Ruins High Tier Offscreen 1440p). This sets us at ALMOST Adreno 630 performance in that regard (we still fall about 10% short). Results in other benchmarks vary though.

This sets our S8’s GPU performance at 764MHz at 5.16% circa on Userbenchmark, putting us a exactly at UHD 630 level of performance. That’s not bad, is it?

Kinda frustrated that now my friend’s S8 destroys my Note9 🤣🤣🤣🤣, but without proper xda support on that device, not much I can do, wish more people were aware of the truth about the E9810 lmao. I’ll upgrade soon to ROG Phone 6 Pro.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
woah ROG i never have ROG family phone but i have tuf laptop for phone i still struggle to earn money just buy lg v50 ahhaha
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I have an Asus ROG laptop. ROG phone 6 pro is out of stock currently which was frustrating. I’ll have to wait.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
maybe can you giveway to some your old devices hehe or maybe for dev ahhaah
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I like to collect and keep devices. Besides, ace doesn’t seem interested in development of other kernels right now, and for a good reason.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
okey hehe
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
It’s been days though since the last time somebody else other than myself started a new convo in here.

So this is it, lmao. Well, it has been a trip.
[Samsung Galaxy S8 & S8+ Cross Device Development] opensourcefreak:
When i install this kernel i get stuck in the boot screen (Samsung galsxy s8 powered by android) Model: G950F Exynos variant
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Then you did something wrong. Check post #1 for "installation from scratch".
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
You should definitely be more specific.

Because this problem to me looks like somebody who did not acknowledge that this Kernel is only for A9.

How do I boost the audio for games? When I'm playing CODM the audio is low even when the volume is at 100.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
CODM has notoriously low audio, just like PUBG.

Check if there are audio settings in game. Otherwise, wear headphones.

There are apps to boost the maximum volume of the phone but they will quickly damage your speakers.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
the first boot took about 20 minutes or so, if you followed the guide to the letter then just be patient..
[Samsung Galaxy S8 & S8+ Cross Device Development] Arnz09:
I already put all the game audio settings at 100 and my phone at 100 but still low audio. Is there any good app to use or magisk module that can help?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
GOODEV Volume booster on Playstore.

USE AT YOUR OWN RISK. I am no speakers functioning expert, but this is pretty much a speakers overdrive as far as I know. And just like excessive overclocks, it is DANGEROUS.

I previously used it on my Galaxy Tab E without moderation, and it damaged my speakers when using them above 70% volume, and while they still work at those levels, they have noticeable distorsion.

As far as I know, there is no other way to boost volume. I DO NOT recommend. Just get some earphones, headphones, anything.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
use viper at magisk app that auto install

that work for me and if you can tune the audio you can increase the audio you want
