Zygisk not working? Is it supported?

[alphapuggle]

Just installed GrapheneOS (not doing it for security before anyone says it, I wanted the sandboxed Google Play), and have tried with both Kitsune Mask and normal Magisk (Kitsune supposedly fixed this, but it didn't have any change).

The issue is that Zygisk will always say that it's not enabled, and the Zygisk toggle says "Reboot to apply changes"

I don't know if Zygisk is supposed to work, I don't see anything mentioned about it in the README or in issues or other discussions. If any logs would help (they would, I just don't know which ones) let me know.

You might wanna read this.

Seems like Magisk Delta was the solution there. However the rest of the issue is interesting as well regarding GrapheneOS. Which you might reconsider if root is important to you.

I've been maintaining a version of Magisk that specifically fixes Zygisk on GrapheneOS (since I use it personally) which will always be in sync with upstream version of Magisk.

You might want to check that out here if interested: https://github.com/pixincreate/Magisk

Rooting is discouraged given how greatly it reduces security unlike other unix based systems and only use it only of you know what you're doing.

So FOREGROUND_SERVICE_SPECIAL_USE requires special system level permission?

Nope, no special restrictions on that. It's available to all apps.

I'm thinking of moving that feature behind a feature flag such that, if the device does not have root access, then call recording during BFU should not work.

Yeah, when I said the new feature might make things harder to implement, this is the sort of thing I was referring to. (One more thing that would need to be disabled/removed for rootless operation.)

Oh, I see. I'll give it a shot then. And yes, I'm an "ultra beginner" in Android 😅

I compile my own version of GrapheneOS and integrate Magisk into the build system

What's the benefit of doing that instead of patching Magisk into OTAs with avbroot?

[ubergeek77]

There isn't one, I just like building GrapheneOS from source and applying my own UI tweaks.

applying my own UI tweaks

Like what? I'm intrigued

pascallj and pixincreate already gave good answers for Magisk forks to try, but I wanted to point out something related to this:

I don't see anything mentioned about it in the README or in issues or other discussions

All of the Zygisk components are executed after most of the system is already booted. They are not part of the boot image and there's nothing in avbroot that would affect Zygisk specifically.
