[KERNEL] [9] A2N Kernel for Galaxy S8/S8+/Note8 (Exynos) [CPU/GPU OC/UV] [Charger Control] [Thermal Control] [R63] [STABLE]

[Askael]

Power profiles from the (stock) ROM doesn't control CPU/GPU Freq at all.
It's only for screen brightness and resolution.
Even if you can set "reduce CPU speed to 70 %" once you check with any CPU Freq app you'll notice that the CPU Freq is still running at max Freq 2314 MHz.
Tested even with stock kernel on stock ROM, it doesn't work at all, samsung or google failed here.

So, i do suggest to keep there "optimized", keep "adaptive powersave" disabled and go with A2N profiles, the only thing that really works lol.

Hello. thank you for your hard work. one request - can you somehow correct the control of the flashlight? due to the fact that your core has control implemented, the brightness is not regulated by standard means. I'm not going to buy the app, because I just want to install the kernel and forget it. but it is inconvenient without adjusting the brightness of the flashlight

dev this kernel so amazing bein usin the latest version encountered 0 problems
using 2002mhz on lil core and big 1807mhz its stable

my question is i got bored of android 9 i want to uprgade to android 10 oneui 2.5 but i want to ur kernel on it
so u still workin on it ? if possible i would like to test it keep up the great work

For android 10 this kernel must stable first very² stable like stock kernel no faced problem or less bug if that realized next for note 8 and go to a2n AOSP after that maybe for android 10 may be you will be wait a long² time

Try with zram.sh 0 for now.

random reboot while it was idling/standby.
I don't remember my setting about cpu clock but I believe just a little bit oc.
LMK 64 Swap 50%
I don't know why I can't attach the file.

with 2.7ghz it restarts 2 minutes later.rom stock zram deactivated, cpu LITTLE 1.8ghz.

This report is for kernel build from 06.02.2021.
I don't provide support for such old releases, therefore i suggest to update to the latest build.

Just got a random reboot while reading the comments of a paused YouTube video.
Profile: balanced
Zram:50%

Got another one while spotify was open.

Something went wrong with the log .. there is no useful debug data.
Generate the log right after the random reboot happens .. do not reboot yourself before or even worse do not shutdown the phone.
Update: maybe it was a "soft-reboot" ?? if so you need to grab logcat then reboot and grab last_kmsg.
But actually you guys should only report bugs for pre-18 build i had uploaded last sunday.

Was it from pre-18-build ?
OC was 2652 MHz.
Anyway there is also no useful debug data.

The provided logs looks normal, hence the reboot reason was not "random" but normal by "user-request".
At least according to the logs.

Summary:
actually i don't have no one bug report for the pre-18-build i had uploaded last sunday.
Anyway i do is still believe that it's not fully stable, at least with zRam enabled.
Still searching for bugs.

Hello, thanks for you report ! - This is actually a good finding ! - So far you are the first who reported this. When i had added "Flashlight Brightness Control" i even didn't know that it's possible to adjust it over stock kernel or stock ROM.
Therefore the default value of 5 in my app/kernel corresponds to the stock value of the stock kernel of "3" (same brightness). Anyway my value of max. "15" is still higher than the stock value "5" in terms of torch brightness. Also i don't know if i can manage to make it possible to control it over stock method + my custom method together. If i can't fix it due to possible interferences then i've to say sorry, but i'll check this and inform you.

Dev try for GPU oc further.. I know it's not easy at any rate.. but I bet that you will definitely do it if you want to

I believe it is pre-18 build.
Kernel version says " 4.4.111-a2n-gb4be8194 #4 Sun Apr 18 23:36:18 CEST 2021 "
I think it was a soft-reboot instead because I didn't hear any vibration from my phone when it was doing random rebooting. But I'm not sure.
When I caught my phone doing that, the screen lit up with my lock screen.
there was no notifications or anything at all (just like when you reboot your phone) and I have to put in the PIN.
and my youtube-vanced is gone. I have to reinstall it everytime it reboot. So I though that it was doing random reboot, so I export the last_kmsg file. (and that's the log you got)

Actually, after I export the log, I always reboot my phone again. This should explain the "user-request" thing.
Since what happened maybe the soft-reboot, the log will not contain about that I guess? So it show as "user-request" instead. (Since I reboot my phone before the soft-reboot happened)
I don't really know about that, I may be wrong.

@ up
why you use "vanced" ? It's outdated app and was replaced with the much better app "pure tuber".
It think that's the reason why it gets uninstalled automatically, nothing to do with kernel issues.
Btw: for now it's not needed to post logs related to random reboots. I'm working on it.

Actually, it just update just a day ago. quite new (except for the magisk version, it's so old)
and I'm using the root version, so it acts like a real youtube app.
but the problem above seems to be from the app, I may have to report to the dev.
Anyway, I have found the sweet spot between the performance and the heat. and it's working quite well!
Thanks again

 

[ace2nutzer]

But "pure tuber" is lots better.

Hi... i'm new again here... long time since era Xperia 2011 line... hehe

i used to flash custom kernel but without root.. because i just simply want to get benefit of custom kernel without loosing mobile banking ability...

yes, i have tried with magiskhide, etc. but it encountered problem somehow

is it possible flash this kernel without root?

With MagiskHide enabled it should be possible to use banking apps.
Also you should test with "SafetyNetChecker" app if it's green (passed).
If it's green and your banking app still doesn't work, then you should report the issue in the Magisk thread.

i've tried, untill safetynetchecker is green..

i'm also try with riru and LSPosed

one m-banking works, another not.. it looks like m-banking apps nowadays more advance in detecting root...

i'll do ur advice...

Good news: i was able to fix it. So it'll be fixed on next official a2n kernel release.
btw: it's OK if you don't mind about the full version, kernel works fine out of the box.
But keep in mind that you'll still have to update from time to time the kernel, since (for now !) there is no feature implemented that informs you when there is a new build ready to flash.
For now the best thing you can do is to "Watch" the thread, then you'll be informed about new releases.

You are so amazing, dude! Thx for you hard work, impressive job.

There will also be a small request. can you make it possible to switch selinux to enforcing and permissive mode from the terminal or by using an app like Mtweaks. This can be useful incase your banking app requires an enforced phone (e.g. rebooting)

Yes you can if no root just some few feature cannot functional properly
