[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
the latest version is waaayyyy muuucchhh better than any previous releases.. why would you need that specific build? every version changes always carries over the features from previous releases unless stated otherwise
[Samsung Galaxy S8 & S8+ Cross Device Development] karan68:
If someone has that ver pls provide

Need to pass safetynet without magisk

And fake enforcing selinux status
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Theres no otherway to pass safetynet than with magisk, also somewhat every custom kernel you can use you have to pass safetynet with magisk.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
It's still implemented in kernel, only removed from the app, because it caused some weird side effects.

If you want to test it, you need root (magisk).

Terminal emulator app: (only for current session)

su
echo 2 > /sys/fs/selinux/enforce

If it works, you can set it permanent over init.d script:

Just write the same cmd without "su" in /system/etc/init.d.a2n/a2n_user.sh

Or if you don't have full version just use "init.d" and write the cmd without "su" to "99_user.sh".

Use any root browser app text editor for this.
[Samsung Galaxy S8 & S8+ Cross Device Development] karan68:
Thanks bro👍 , made the changes as you said and it passes safetynet also no issues with bank app.

By the way what are the side effects of enforcing kernel you said..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Why you don't fix safetynet with magisk? It's the proper way.

Fake selinux works too, but I remember that I had faced that some kernel settings will be locked and can't be changed by a2n app. Not all, but some. When I've time i'll review it again.

Dev report your twrp.tar for note8 make the odin flash always force close i have note 8 right now i use twrp from corsicanu version 3.7.0
[Samsung Galaxy S8 & S8+ Cross Device Development] Just_try:
Sir Ace,one question here

why does the a2n kernel application take a long time to verify the license?

Thank you mr.Ace
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Ussually took 5min long but in my case just 15 sec
[Samsung Galaxy S8 & S8+ Cross Device Development] Just_try:
Yap,it's okay

I thought only mine was like this

Thank you
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
i think it depends on your network speed..

i never have a problem with license verification, it just blips and its done..

you might want to try setting your private DNS to google DNS
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
For me it's just 5 seconds.

Sometimes it can take 10 seconds if there is server issue.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32021:
I tried the a2n kernel last year, the device restarted in deep sleep, overheated, the battery didn't last long. so i went back to hades 1.4. today I put a new battery in the original S8+. so I thought again to try a2n kernel version 55 because I think it is probably ideal now for the battery without overheating and restarting. unfortunately, even on the latest version of the kernel, my S8+ overheats, and the battery lasts as well as the stock kernel maybe even worse. So I went back to hades 1.4 and i have a great battery without overheating. sorry developer but for my exynos variant this definitely does not work, I tried everything and the app.

S8+ lite rom pie.

Also I try on hades 9 pie.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@Ac32021

This kernel is now 100 % stable.

First boot with this kernel + wiping dalvik-cache will perform highest level of apps optimization and this takes around 20 minutes and after this the device feels very hot and battery level goes down. That's normal and on second day + second full charge, everything will work perfectly. I suggest to test for 1 week, because you can't test battery life in just one day. This is the only kernel where you have full control over device temperature, performance and charging speed, again connected with adjustable charging temperature.

If this kernel is too complicated for you, then use other custom kernel.

No problem for me, I use a2n kernel and I love it. I even don't care to upgrade the Android version, because Android 9 stock with A2N kernel is still cool, as I don't want to loose all the great features from this kernel.

Good luck.
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
I think something is wrong with the kernel. I had my battery replaced on galaxy s8 sm-950fd. I overclocked the device to check the performance with gaming. And yeah I didn't use unstable frequencies. Later I got battery deterioration notification. Then I checked a2n kernel control application, it shows me 85% capacity which is 2596mah.

I request other users to check their battery capacities and respond please.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
might want to give it full 4 days run, and try wiping cache & dalvik from the recovery..

you could see my posts from previous page.. 4th day is a completely different battery life with the same usage. it might be the android systems trying to figure out your usage patterns
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
SM-950FD user here, 88% with 2626mah..

currenty charging at 54%

have you tried reclibrating after your charge reaches 100%?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Honestly pointless to update to A10 or A12 or whatever on S8 if someone's planning to run A2N to begin with. You basically ported all the nice to haves to Android 9 anyways, so if it's performance alone a person is looking for, A2N provides that and more.

This is a problem on other devices that don't have Kernels like A2N. They have to rely on Android updates to get better drivers.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Here my screenshot for battery capacity. It's still the original battery.

Btw after you replaced the battery you need to perform a reset (see screenshot).
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
This gotta be one of the best examples of “Say nothing while saying a lot”

“My phone overheated” lmao did your S8 tell you? “Daddy I’m hot”

Hades Kernel is just stock Kernel with sugar coating. It’s not that it has long lasting battery and doesn’t overheat, it’s just that it is as conservative and as slow as stock kernel.

But to each their own I guess.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
G71 764MHz run. No throttling. This is as fast as Adreno 630.

At stock 546MHz the score is likely around 28fps. At 572MHz it’s 30fps.

839MHz would require 850mV to be stable and throttles out of my control. So this is as high as I can sustainably go.

Ideally 839MHz should manage 40FPS. Apple A11 for comparison does 49fps. Snapdragon 870 does 64fps.

E9810 at 598MHz does 33fps
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
So after reset, does it shows real capacity? Cause I didn't know that. And now after your reply I pressed reset in the app..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes, it'll recalibrate. But when it's 100 % charged with green LED then unplug the cable and tap on reset.

After 1 week you will see real capacity.

In addition you can also reset charge cycles, but it doesn't affect battery gauge or battery life.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32021:
I might type it wrong since I'm bad at english.

My device gets very hot performing basic tasks, no games never, just chrome, aliexpress, instagram, youtube. Nothing more.

Cache wiped, device get very hot. Doesnt need device to tell me. ;)

I'm just saying hades kernel very good still compared to this.

Yes kernel is stable, but I dont see battery improvement, maybe even worse than stock kernel (no adjustments made in a2n kernel app), just heat, nothing more.

That is my experience with exynos, my phone is in mint condition, battery replaced original.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
My phone has a shattered back, has a 5 years old battery and was used constantly ever since 2017. It doesn't heat up much at all in daily usage despite my aggressive performance preset. I do agree that battery life is subpar, but that is not a problem to me since I always bring a power bank with me, and it's also likely due to the old battery.

Hades Kernel is merely stock Kernel with extras, like I said before, and there's nothing in that package that is significant to me. If it worked for you, good. But know that my experience with A2N Kernel has been very positive, and this is an absolutely amazing Kernel.

To each their own.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Maybe you can take look your simcard network if the where you live is have bad network for simcard the phone will heat up because always try to find the network

And for social media is get hot because the input booster

When you scroll that smooth like iphone if you use it try turn off it

If you still get hot i mean to hot like 40 or 43°c in ambient room 30°c something went wrong in your phone app maybe there is something running background too much make it hot

Because this kernel have fast performance in any temp untik the phone burn your hand

Try check with usb debugging

adb shell <enter>

Top <enter>

It will show like taskmanager and that you phone process
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Whenever people have these kinds of issues, it’s most of the time user error. He 100% has something going on that is causing his phone to overheat when using A2N Kernel. I wouldn’t be surprised.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yeah or if not user fault then it's possible that this kernel isn't 100 % compatible with the custom ROM he is using.

This kernel is only 100 % tested and optimized for the Samsung ROM.

Anyway, a power-user should be able to detect what's causing the overheating by running "top" utility like @rtyuakatsuki said.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
as i posted weeks ago..

https://xdaforums.com/t/kernel-9-a2n-kernel-for-galaxy-s8-s8-plus-exynos-r55.3875640/post-87803829

first boot took a while and it seems that its running the cpu unthrottled, thus creating heat.. first day battery life is kinda drained, but after 4th day then it shows a really big difference..

you'll experience similar things like this after you change your rom or changing kernel, so try at least 4 days and see what happens.. you wont regret it
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
My s8 is dead... rip this amazing phone that stayed with me for 5 1/2 years and had display destroyed after I fell with my hips over it while working physically and it got wet in the rain... I might fix the display in the future but for now I bought a new one, s20 Fe 5g Snapdragon processor...

Dev I remember reading some posts ago that your code to use mainly little cores could be ported to any Samsung, could we talk about porting it to the new phone? There are a few people developing kernels for it but I'm not sure what has been achieved. I haven't even rooted it yet.

The s20 is a good upgrade but the battery life isn't really that great...

Thank you developing for making my experience with the s8 so much more enjoyable. I really appreciate your work.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
If you want it you can port it but that will took long time and your device is snapdragon well that difficult to root because snapdragon have security inside the soc diffrent with exynos can be unlocked
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Yea its sad with s10 and above they are difficult to unlock and root with their new Security inside the soc. Well time of easily modifying a phone is gone since few years😐
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Well actually there are a few custom rooms and kernels available, that are being maintained. No difficulty in unlocking or rooting from what I've seen.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yes in s10 as i see to get OC and voltage control is change the DTB and DTBO that high risk chance to get brick
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yup i feel it that tho and xda developer has less active i think in development but in telegram there is much group and channel provide file to modify system and have big risk tho
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
It's not possible to softbrick the phone with wrong kernel or dtb. Softbrick only possible if you mess around with the bootloader.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Even if you brick the bl there is a way to recover from it, maybe not easiest way but guess it requires a chip reader/flasher.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes I know, you need a riff-box and you should know how it works.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
True, but still there are plenty of guides and how to's/tuts for it😛 but still agree with it can be tricky if youre using it for first time. But thats with everything lol
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
You mean chip flasher right? That need pull off the chip :v
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:

[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Just get S9+ or Note9 and install Custom Kernel. Becomes faster than Exynos 9825 and on par with 990
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Really ? That 10nm btw :v
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
That 10nm is beast. I don’t think anyone here understands how fast it really is. GPU slow but with OC it’s fine. Cpu is blazing fast and can almost match A12 Bionic while running at lower frequency.

Its not like Exynos 8895. Samsung held 9810 back. Because it was too powerful
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Here. And it can do more
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
The heck okey i think better get note 9 hehe because that have a note pen hehe and good camera tho i hope i can buy it as cheap possible :v but first i must made success my gps tracker

And btw what kernel you use?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
xxTR V44 Lite V2. You should get in the telegram group if you get the phone, because it’s on on XDA yet.

Also ideally you should install noble rom A12 on the note9, since no dev ported gpu drivers like ace does. So only way to get better performance is by updating system
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Ah i see that make the process more light for gpu and cpu and btw our dev want to add the new driver but it will consume much time and makw instability in android 9 i guess

And okey bro i will make and spend for note 9 hehe for today price in my country the price like 190 or 210$ good used
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Ace should if possible DEFINITELY port the A12 R32 Mali GPU drivers over to A9, but it will be a DIABOLICAL amount of effort, and I'm telling him. A10 doesn't support many of the libraries that R32 has, let alone A9. But the performance increase is about 13% while remaining at same clockspeed. So basically a Mali G72 at 598MHz on A12 is about as fast as a Mali G72 at 683MHz on A10. It's plenty profit.

It increases the AnTuTu V9 GPU score from about 136,000 to 152,000+. That at 598MHz. It is a shame that Mali GPU drivers only grow to be great after so many years. Because just now, in 2023, the G72 MP18 reached the Apple A10 GPU performance at 598MHz. With A10 it was still behind. It took A12.

If it's worth it in the long run (since everything in this Kernel is pretty much figured out) he should try to do the porting.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yeah he should do it the problem our dev has not much time and focus about his real life if we want he porting it how about we made a donation for him :> maybe can help him
[Samsung Galaxy S8 & S8+ Cross Device Development] heukpyo:
I wrote this using a translator because I am Korean and I am not good at English.

ROM: Samsung stock ROM

Kernel version: 55

A2N app version: 55

BUG: lag,beep sound?

How to reproduce: game

Same bug with stock kernel ? : NO

I was using an a2n 4.4 and this happened when I upgraded to 55.

Reinstalling the kernel doesn't change

If you look at the attached video, there is a strange beep and lag during the game

This beep is what happens in every game.

When I listen to YouTube or music, I can't hear this beep sound

However, screen hangups still occur.

Even if you touch the pm-qos-big/little setting in the a2n app audio setting, it remains the same

Of course, we didn't use unsafe frequencies

It's the same if you set everything as the default setting

This does not happen when using a different kernel than the stock kernel.

Is this a kernel error? Or is there a way I can work it out?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Holy **** buddy this is not a normal beep. This isn't a beep at all. This looks like the whole phone hangs for split seconds before continuing to work. That's not a good sound. At all. If it shows up only when gaming and not when normally watching videos, it means the problem presents itself when components are under stress.

Things to check:

1: Verify whether this problem still appears with phone plugged in fast charge

2: Send your ASV values and voltage table

3: Lower big cores peak frequency to 1.46 and GPU to 455MHz and verify if problem still appears

4: Check and report your battery health percentage and voltage.

@ace2nutzer check this out. Could be hardware problem but he provided logs and only you can look into those
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@heukpyo

A2N app: GPU --> voltage control: set 750 mV for 572 MHz step.

This should fix the sound issue.
[Samsung Galaxy S8 & S8+ Cross Device Development] heukpyo:

4: Check and report your battery health percentage and voltage.

I still use a translator, so there may be an incorrect translation

.1. It keeps happening

2. I don't know what ASV is. I recorded the voltage table.

3.Even if you set it like that, it keeps happening

4. 100% 4.35v

Although there is a strange sound only when playing games, the screen stops when watching YouTube or on the home screen.

If you look at the video I posted, you can see that there is no strange sound on the home screen, but the scroll stops

And even if I raise the voltage of gpu and cpu on the a2n app, it's still the same
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Only anomalous thing I could spot is that your GPU voltages are exceptionally high, but I can't see how that would cause these issues. So the screen still occasionally freezes just without making the sound.

Well the sound itself occurs in games because there's a high chance that at the time the freeze happens, a sound is playing, so said sound freezes too...but that's not the point. This is an especially odd problem.

Try to run screen on 1480x720 unless you do already. But I'm staring to believe this might be an hardware issue, so I'm focusing on trying to make you find a way to stabilize it at very least.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
It's not hardware issue since he said it doesn't happen with the stock kernel.

Unfortunately actually I don't have time anymore to fix the issue or to update what ever drivers. So for now use it like it is or switch to other kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I face it sometime when battery at low or at the high or extreme overclocking

If you get beep when playing something that cause the cpu has low voltage but in your video you use kind of save mode freq and 572mhz gpu

The beep cause by cpu

If that hangs cause by gpu better try stock freq first

Edit

After read all your post maybe tge lag cause by zram ,swapiness and other in ram section try turn off zram if still that cause by kernel it self
[Samsung Galaxy S8 & S8+ Cross Device Development] heukpyo:
I gave up on fixing it and put it back on stock kernel

If you don't mind, could you please send me the previous version of the kernel and the app?

I can't find another suitable kernel

I'm so sad that I can't use it after using it well

I would appreciate it if you could send me an older version of the kernel that would work well
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Development is actually paused on my side, in future i'll resume development for this kernel and app.

(Maybe in around 6 months)

The sources are online and there is also how-to-build this kernel.

That means every kernel developer will be able to work on this project.

It's not possible for me to provide older kernel or app version. Because I don't have it and also it won't work well at all. This is for security reasons.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Bro i forgot to tell you

There is lag between freq change

You play game that need respone time

When you play that game the cpu freq change frequently and that the problem try performance mode and limit the max freq the lag will gone
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@heukpyo

Maybe this helps you:

the sound issue you are facing is usually caused by one or some of the following scenarios:

1. GPU voltage too low (audio hardware is powered from the same voltage buck like GPU)

2. Audio PM-QOS in A2N app is set too low. (Make sure to set at least the default)

3. Big CPU Freq is too low or load is too high that there is no more CPU cycle left for audio processing. (Increase Big CPU Freq)

4. Big CPU Freq is high enough, but CPU DVFS Freq is only at 65 °C (default) and your phone is already heating up from games or fast charging (over 1500 mA) and this cause big CPU to throttle and you face audio issue) ... fix: increase CPU DVFS temp to avoid throttling.

As you can see there are at least 4 different scenarios that could trigger audio glitches. Try all 4 points, you can manage this easily and comfortable over the full version of the A2N app. If none of the 4 points helps, then let me know, there is one last thing you can try over ADB or terminal emulator app to force INT Freq to increase together with input booster. Last one is not a fix, but at least a workaround for now.
[Samsung Galaxy S8 & S8+ Cross Device Development] MfmeheyitsmeIam:
Sorry to bother but did you actually increase the cmu's max frequency? I'm trying to overclock the gpu on a exynos 9825 m62. But kmsg shows 754 as max. How did you increase it?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You can only OC by using max freq from ACPM firmware. See in post #3 section "how to edit voltage table".

The highest freq you see there in your last_kmsg will work at least with higher voltage and if your SoC can handle this. Maybe it's even possible to set higher freq than this, but requires more deeper hacking and in our case it's not needed at all since the stock freq table from ACPM provides already high enough freqs that our SoC could ever handle. Other than that, see my commits how to force max freq from ACPM.
[Samsung Galaxy S8 & S8+ Cross Device Development] MfmeheyitsmeIam:
So on your device if you were see last kmsg it would show the 834000 but the phone would only go to 537? How can I increase the last kmsg value?
