This is also true for DivestOS as a whole.

And now do it without Google.

AudioRelay?

Neo Launcher is pretty nice!

It’s simply a risk. Android is designed how it is for a purpose.

I still use a custom ROM, GrapheneOS - which also strongly recommends not to root your device!

2. This could be due to missing Google services?

I wouldn’t say that GrapheneOS isn’t ready for daily use just because you have some issues. It’s a mature project with decent support for only a couple of devices and a lot of people use it on a daily basis without issues.

Don’t use the Beta channel and expect everything to work.

I don’t use Google at all but theoretically everything should work with the sandboxed Google services.

And I did use Nova Launcher and it’s working without an issue. Importing a profile should also work.
