The battery using this kernel got a noticeable improvement! I think I got about 1h sot more with this kernel after configuring it
And my screen off drain went from 1.6% to 0.4% which is awesome!
Thank you very much
(Btw do anyone know what the battery-sec-monitor wake lock is for please?)
Good to hear that👍

Magisk Hide option has stopped working after upgrading from 1.4 to 1.5
Install new app, older will never run again. So v23 cant be in use after installed v23.1 - magisk some disable for it.

Hey, I installed v1.5, installed the new Magisk apk and updated to 23012 but I can't pass SafetyNet, do you have any idea please?
I also enabled the Zygote thing and ticked the "override" thing to enable some other apps (I enabled Play Services)
I use Viper4Android, Busybox and Systemless host modules

Using the safety net app I have
Safety Net Request: Success
Response Validation Signature: Success
Basic Integrity: Success
CTS Profile match: fail

In my case, SafetyNet check fails too. I think, we should wait for a simple solution. However, it looks like it's not critical for apps I'm using. A stable kernel like this particular one is more important.

Yep, also using the non-updated magisk from the Kernel it keeps asking me to finish the installation step and reboot when I launch it.
By enabling play services "gms" and "gms.unstable" in Zygote I got the first part of SafetyNet to pass but not CTS

It also says that my phone is a G981N for some reasons

As You see on mine works well with 23.1. In attach settings in magisk. And module...only safetynet fix v2.0.0 edzamber (riru, etc. are absent) Googleplay services in hide.

I have one more unpleasant issue with the Kernel. My phone randomly restarts 1-2 times a day. However, it doen't seem to be a full restart when you see all those messages about unlocked bootloader and custom ROM warning, it makes quick reboots to the SAMSUNG prompt.

I dont know, I dont have this issue and my testers team too.
Maybe some magisk mod or another app for auto optimize system,...

Too much UV in POWER section, maybe too much OC, idk. | try reset ttwekas data in app - Restore app settings.

Yes, it can be anything. Most probably, this is an incompatible old application or a hardware issue. Even phone cases can cause quick restarts.

Same issue here, it's not annoying at all, it only happened when my phone was locked
I'm using V4A, Busybox, Magisk Hide Props and Power save CPU kernel mode

I have no V4A anad Power Save. Actually, my phone configuration is rather lite. It's possible that Magisk can make a quick restart. Moreover, static electricity may produce a similar effect. People on the Web say there can be some hardware issues too, including an exotic issue related to a phone protection case. In other words, I cannot say that the Kernel version causes this problem.

After few weeks of use I am getting an astonishing 7 hours of screen on time! It's crazy good for an Exynos base S20! Thank you so much for this kernel
I was getting 5 hours of screen on time before

I am using Bluetooth connected to a watch
120hz fhd+
power save cpu governor
My phone is debloated
My usage is like 10% gaming 90% Reddit, Discord, web browsing etc
The idle battery drain is high because I'm often listening to music while my phone is locked

So very good...congrats. You even heavy use the phone so is very nice.

Btw... in new version (now in test) Ive added possibility for set devfreq MIF frequency settings so we can drop down from max 2730MHz to e.g. 2288MHz and this gives less battery drain too... so will be better 😀

    Hello. The kernel works and I have root rights, but anything I do doesn't work with the magisk hide! can somebody help me? The switch is back gray.View attachment 5461481
    In kernel zip is magisk 23014 with zygisk, if you have app v23.0 this will not work, you have to uninstall older safetynet fix and install v2.2.0 for zygisk, next enable zygisk in magisk and add bank apps in Denny List.

    More you will find on telegram group.
    Works 100%. Tested by users.

    Thanks. The hide works, but now the magisk modules don't work and there are no module downloads. What do you think? What to do?View attachment 5462135
    New Magisk blocks, no more online mods in magisk. You have to look on xda or githubs.

    i flashed it after the beyondrom but the tweaks app is not installed?
    Open the zip. You find the .apk here: \data\media\0\Apkinstaller\
    Install it manually.
