hey this kernel working fine from release now with zram 0% . as I'm not playing game due to performance issue I set it to 0%
[Samsung Galaxy S8 & S8+ Cross Device Development] TeKeyTech:
When I connect my phone to laptop, I can't seem to run dex (A2N kernel installed on stock rom).... Please how can I fix it because I saw that dex is installed inside my phone but didn't appear in my notification panel or in settings :/
[Samsung Galaxy S8 & S8+ Cross Device Development] island3r:
So, newcomer here, should we use the latest stable or test #23?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Welcome :)

Test #23 for now please.
[Samsung Galaxy S8 & S8+ Cross Device Development] island3r:
Thank you for your time mate. I will.
[Samsung Galaxy S8 & S8+ Cross Device Development] Terminator-ios:
@Ac32021 It's not nice for developers to make thread comparisons worse and better, each kernel has its own particularities. However now we are still in the testing phase, in the latest versions the battery has improved a lot, surely you are using an outdated kernel version.

Kindly respect the work of others.
[Samsung Galaxy S8 & S8+ Cross Device Development] panda.musty:
I was using this kernel with stock ROM and I'm trying hades q now. According to my experiences this kernel is better than hades for battery drain. It depends many thinks. There is not a best kernel or ROM. Which one is good for you, just use it. But pls don't blame on devs. If you find any bugs, report them. They need support.
[Samsung Galaxy S8 & S8+ Cross Device Development] Terminator-ios:
The A2N kernel goes better with the Stock Rom, but the nice thing is that everyone can adjust it depending on what they want, performance or battery.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32021:
Random reboot happened few minutes ago.
[Samsung Galaxy S8 & S8+ Cross Device Development] Badger50:
Greetings to all. I certainly hope everyone is doing well. Just a friendly FYI if I may regarding some of the recent postings I've seen. While it is ok to report bugs or issues you may be having with any rom or kernel, it is not ok to disrespect, or compare one developers work to another's in the hopes of trying to motivate a developer to add something to their work that you might see as beneficial.

If you are having an issue, then please report them respectfully, and possibly include a Logcat whenever possible, which always helps the developers recognize what the problem that you're having might be. Always remember this simple, yet paramount fact as well, all developers on XDA do this for free for all of us, which IMHO demands and deserves our respect and gratitude. For without them, the freedom and fun we all have on XDA to modify our devices, will no longer exist. Thank you for your cooperation, and a pleasant day to all.

-Regards: Badger50
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
For this specific thread i want to add to post always those informations after you face any issues:

Phone:

ROM:

Kernel build:

A2N App V.:

And post last_kmsg + logcat. (You can get the logs easily from A2N demo App in debug menu)
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
How is battery life with this kernel on Hades q V2 for you? Better or worst than stock based ROM? Thinking about trying it also, but only if battery life is good...

I love a2n kernel anyways
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
A2N Kernel still only for 9!
[Samsung Galaxy S8 & S8+ Cross Device Development] Terminator-ios:
Better the stock ROM for stability, battery life depends on which apps you install and use and on kernel settings, there is not much difference with other custom ROM (I have tried them all).

Of course I'm talking about android 9 and One Ui.
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Got it, I thought you meant Android 10, don't know why I thought this kernel could also be used with Q....
[Samsung Galaxy S8 & S8+ Cross Device Development] panda.musty:
For ROM, it is good because it is android 10 with UI 2.5. Stability and battery drain are not bad. You can try for daily usage.

For kernel, A2N is better because A2N control app more useful specially for OC and battery drain.

Don't scare, use both of them and choose which one is good for you

I wish I can use Hades ROM Q with A2N Kernel lol 😂😂
[Samsung Galaxy S8 & S8+ Cross Device Development] Terminator-ios:
personally for performance, stability and battery I continue to prefer Android 9 over S8.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I just got a reboot with test kernel #25
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Second reboot happend test kernel #25
[Samsung Galaxy S8 & S8+ Cross Device Development] Applepiss:
Hello i am new, i have the stock rom and i installed the rz kernel, but now i would like to try this, can i install directly or is there some particular procedure to do, i would not want to delete everything again?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hello, you can flash it over the old kernel, no problem.

I suggest to wait for new release, since latest one is unstable.

Alternatively you can try the one from "test" folder "test #23".

But even test #23 is not fully stable.

Stability will be improved in new release.

At least i'm using the future release for few days without any issues.
[Samsung Galaxy S8 & S8+ Cross Device Development] Applepiss:
Oh, great support really thank you, I'll do this, in the meantime I'll be using version 23.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer maybe stupid question, but is it normal with your kernel that apps close automaticly when multitasking with multiple apps? Didnt happen when i was using rz kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Foreground app or some apps that was running in background ?

Also with which build that happened ?

zRam = ?

LMK = ?

Or was it with kernel defaults ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Foreground apps mostly, and yes im running it with everthing on standard settings, lmk on 192 mb and zram 0% now. Im using test kernel #25 and also tried also older builds. Didnt have that issue on rz kernel. Normally it doesnt matter but now in the case of me when im buying something in chrome and accepting payment in my banking app and then i loose progress becus chrome was closed down. Happend multiple times.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Hi dev i got same problem like @Ryujin96 but when i play genshin impact all background apps got froce closed i dunno why and sometime phone forceclose the game and same problem to like him when multitasking always close too when i move other apps for 5 or 10 second any fix for that ?
[Samsung Galaxy S8 & S8+ Cross Device Development] Applepiss:
Hello developer, I am trying the version 23 of the kernel as you advised me, I must say that it is very fantastic in terms of performance and fluidity, I also downloaded the control application but it does not work, the Cpu frequencies are not set why?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Because some functions are disabled in the test kernels, its more for testing the stability of it so you cant overclock with it, guess i say it right.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Okay, im 3 days stable with the test kernel #25 on standard settings but ill test it longer, if any crash happens i'll let you know @ace2nutzer
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Random reboot happend an hour ago, standard setting with zswap enabled 50% on test kernel #25
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Thanks, i'm already aware of instability, battery and multitasking issues.

Everything will be fixed on new release.

It's planned for the next 8 - 48 h.
[Samsung Galaxy S8 & S8+ Cross Device Development] lmegogol:
So, when it ll be arrive?)
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
This week i guess, patience rewards dude :)
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
Just back after week with just 1 soft reboot lol... I don't think I have to upload logs now as dev is already about finish the work for new kernel.. Just can't wait anymore haven't used mobile for gaming for a while now..
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32021:
Glad to see other people facing same issues as me. My s8+ hades rom 9 pie, with a2n kernel reboots also when locked (screen turned off) also battery is not good for me.

Bunch of features and options but unstable sadly... I dont have logs, just waiting to get more stable. Thanks
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Any news about update?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
There was a problem. I think it'll take 1 - 2 days for release.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Any news?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Still fixing issues. - I'm sorry for the long waiting.

Once i'm done i'll upload.

It's not just kernel, i'm fixing also a2n app issues.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Alright, well let us know when its finished😊
[Samsung Galaxy S8 & S8+ Cross Device Development] Prototype18:
Is there any chance this works on note 8 ?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Maybe yes maybe not
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Guess not, its a whole different phone.
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
@dev I guess you're cooking something big this time.. just go slow don't rush.. if we need better kernel then we can wait..
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I'm back from the dead since my S8's screen died. I made sure that my friends remained aware of this absolute monster of a Kernel. Recently a friend of mine managed to defeat a Snapdragon 835 S8 with the latest release, 2704MHz big (his silicon can't handle 2808) and 1898MHz little (again, silicon can't handle 2002). 572MHz GPU. This was something not possible on stock. Ace is just an absolute madlad lmao.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Hi dev from past thread i hear from some user of this kernel say "to know you have good chip is look at bootloader " i forgot he say what some little code to know have good chip or not are you remember it dev ? I want to buy s8+ to for my gaming and the other for daily use
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Some say it has something to do with the ASV number you see in "Download Mode". But i don't remember too if it's better to have a lower or higher value for higher OC. But i think it shouldn't make much difference. So far 2,8 GHz never worked stable for nobody, but for most users if not even all 2,7 GHz works stable.
[Samsung Galaxy S8 & S8+ Cross Device Development] Radulescubg:
I absolutely love this kernel. But I have only one issue. I checked this tread and it seems like there should be a switch somewhere to change selinux to enforcing. Or at least "mask" it.

I checked the a2n kernel control manager from the store, and I don't see the switch any anywhere. Am I missing something or..
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Fake enforcing mode is available in demo app. Check in-app-menu debug.

Google don't allow apps in Play Store that are able to disable SELinux.

If it doesn't help, try MagiskHide.
[Samsung Galaxy S8 & S8+ Cross Device Development] Radulescubg:
Thank you. Found it. Still problems with ING Bank. Guess this kernel has some other changes that triggers the detection in that dumb app.

Still love the kernel tho 🔥
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No problem bro, btw i've also ING-diba banking app.

I'll check it before releasing new kernel and app.

Stay tuned.
[Samsung Galaxy S8 & S8+ Cross Device Development] leonidasZ953:
Thank you for new version,

But I almost install kernel and app too..

When I open app say..This version has reached EOL

please update to the last version..Any fix for this??
[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
i got 3 random reboots within 10 minutes, and if install magisk, the phone is not booting with the new kernel.

Kernel control expired. (or its not compatible with the older kernel)
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Fix for bootloop is downloading & installing the latest version of magisk. Check also you have the correct modelnumber of the phone.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Dev is working on a new version with fixes and new features so thats prob why.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Which problems exactly? Like doing payment with ideal with ing? If thats the case, it was a bug with the ing app, nothing to do with the kernel and they have released already a bugfix for that 4 days ago.
[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
Is there any way to downgrade the a2n app?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Why ?
[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
With the new kernel i have lots of random reboots, so i downgrade it to the prev. version, it works better, but the new v3.6 a2n control app not working with the older kernel, it says "Licence experied, this version reached EOL, please update to the latest version"
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Flash kernel V. 2021.10.29 and then upgrade to A2N App 3.6.

This will fix all bugs.

I'll write changelogs now.

Edit:

@spdrfx ​

Nope, wait for changelog, there is a special note to take care, otherwise it'll not work properly.

[Samsung Galaxy S8 & S8+ Cross Device Development] spdrfx:
Ok, now its working, thanks.
[Samsung Galaxy S8 & S8+ Cross Device Development] MUNISH MONGA:
NEW UPDATE IS AWESOME!!

@ace2nutzer I've been waiting for this build for a long time, THANK YOU !

- It is super stable with ZERO random reboots

- Dark Mode is a treat to the eyes, It's so cool!

- init.d is back, now I'm able to run my scripts without any hassle

- BUT on every boot, I've to launch the a2n app, pass the license check, then only my init.d scripts and settings in the a2n app work,

I think this whole process can be skipped by including a service within app to apply all settings (including init.d scripts) on boot with a toast/notification that settings were applied on boot...
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
I think time that dev took for cooking paid off! its flawless.. lol you just made s10 out off s8... just yeah little underclocked gpu... want to try zram some more.. if you want debuggung then Im also ready to keep stock.. Haven't tried gaming yet
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Report dev i have been install new kernel i got slow respone and performance default are that normal or not ? And how to change HMP ? To use all core i hope you reply hehe
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
maybe dalvik cache clear effect.. it slows down if you clear dalvik cache.. sadly everytime it happened to me also then it took 2 weeks at least to get normal.. this time I didn't cleared dalvik it's woriking awesome dude
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32022:
Followed all instructions for newest kernel, flashed kernel, corected things in build.prop rebooted to twrp, wiped art and cache.

Phone worked for 2 hours like dream.

And then random reboot in deep sleep. Same like older version on S8+ hades kernel pie. Reverted kernel to hades and no problem. Can someone quick explain me if I can attach log and with wich program. because I waited for loong time to release new version. And still bootloop.
[Samsung Galaxy S8 & S8+ Cross Device Development] MUNISH MONGA:
Hmm....I think it would be easy if the app do a one time license check or a license check every time a setting is needed to be changed in the app...if the license check is passed then only onboot service/activity would activate (a2n_allow= true could be set)....then no need to get online on every boot in order to apply those settings or execute init.d scripts...everything would be then handled by that service

Because most of the users, I believe, tend to find a stable config, then they stay on that, well atleast me!. then whenever we want to change something lets just say OC, open the a2n app, OC the freqs, pass the license check, nd we r good!...what I mean is that license check could be done everytime a setting in a2n app is changed and could be removed when it applies those onboot settings & scripts through that service.

Anyways it's just a suggestion, I'm OK with the existing setup also, it's good...

One more thing I noticed is that Touch Boost is enabled even after setting it to 0ms in the app, the freqs ramp up whenever I touch the screen, may be this is because the head event is set to 0 0 0 0 0 but tail event is not set that way. Although I was able to adjust this with init.d...
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
stock settings while using whatsapp
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
With old dalvik cache ? Or did you wipe it ?
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
I agree. I don't like to have my phone online all the time and I also use it a lot on areas without service. Needing to connect to the internet to apply settings doesn't feel good to me.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Nice find ! - Can you please post how you fixed ?

What happened ?

Of course internet connection is not required for just applying your offline settings. But it's required to check for a valid license just before applying settings.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I get what he mean with what he's pointing to, he means after every reboot he has open the app everytime for applying settings, but its not possible if he has none reception or something because app needs a active internet connection when opening the app after reboot for the license check. Thats a kind of problem indeed.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32022:
A2N developer please can you tell me what rom are you using? Seems like you are only best dev for S8/S8+ . I'm searching for best compatible rom for S8+ with a2n kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Sure it's a kind of problem. And somehow only a workaround for now.

I also don't like that, (yes i've to do the same like you) but it's not my fault if Google is not able to provide a proper secure license check library.

They provide 2 different methods of license check:

1. Offline mode

2. Serverside / online check

method 1. is completely unsecure and very easy to hack.

method 2. sounds secure but it's fully hacked as well.

So as an commercial app developer the only way we developers have, is to protect our work with our own custom methods, (since Google completely failed)

I can't speak for any custom ROM's here, because i've never tried one of them.

I'm just using and developing A2N Kernel with the latest stock ROM and i'm very happy.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Okay Clear for me, no other choice then lol
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
I recommend Lightrom v50 pie from teamexykings, its a debloated and optimized and close to stock rom. Also you can install the stock apps from the installer if you miss them and need them back for some reason, also it has some mods in the installer. But look for yourself, nobody can rlly recommend a rom what you likes and suits your phone.😊

[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
I ignored clearing cache.. Clearing it now.. and it was a soft reboot
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I forgot to mention, you should flash also twrp from my FTP.

Flash twrp

Reboot to recovery

Flash a2n kernel

Flash magisk

Wipe cache and dalvik

Reboot to system

This is a proper clean installation method.

This kernel has different RAM layout.

And therefore you need twrp with same kernel otherwise you get memory corruption and get soft reboots and bootlogo glitches.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ac32022:
Yep, this time 2hrs passed and no random reboot still. One and only mistake, I was using TWRP from highonandroid website (some tutorial on youtube). Flashed twrp by a2n, flashed kernel, magisk, wiped davilk and cache. For now works like charm. Thanks dev

Edit: almost 24hr passed.

Kernel is super stable.

Device S8+, rom: hades v12 pie (not the best but who cares).
[Samsung Galaxy S8 & S8+ Cross Device Development] bntnja:
The new version works very well. No random rebooting for me. And the performance is great.

Now the only problem I have is my device itself. it seems like the thermal system in the device is kinda broken. so I have to fix it later.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer hi dev, i have a problem when i leave my phone on idle or using it for a few hours it becomes sluggish and rlly slow and laggy and after reboot its again fast. Do you know what it causes?

Kernel settings:

Cpu & gpu clock speed default settings

Up threshold 50%

Dvfs 70c

Lmk 192mb

Zram 60%

Swappiness default

Touchboost off
[Samsung Galaxy S8 & S8+ Cross Device Development] pranil60:
It seems that my device is charging slow what changes required in a2n app... all settings are unchanged
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Check if fast charging is enabled in the battery settings, and second check if the cable is the problem. I have it sometimes that the accu is slow charging becus a dirty charging port or the cable is not fully in the charger.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Right, sometimes it doesn't detect properly AFC charger due to contact problems. After re-plug the connector from the phone it shows properly "fast charging". For S8, default charging current is 1500 mA while over offline charging it's 2000 mA.

To increase, you have to change value for the proper charger. For any wall charger it's "AC Current Max".

After that check "Charging Current".

You can change current on the fly.

As for slowness after some time: try with LMK 256 MB
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Okay, trying now with lmk 256.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
@ace2nutzer Guess its solved now, only problem i get sometimes is some weird gpu glitch or restarting a app when im using it, like a app refresh without losing anything.
