Yeah let me know when I can install mainline Linux.

Definitely a step in the right direction, but the fact that android uses the Linux kernel but still manufacturers keep so much proprietary… It kills me

I mean… This is kinda close. The “Linux Terminal” app is running a full Debian install in a KVM VM. On the newest version of the app (like on Android beta or on GrapheneOS), you even have a full GUI that you can use.

In theory, we should be able to boot any mainline Linux distro in a VM, if someone writes an app for it, as AVF (Android Virtualization Framework) is just a wrapper around Linux KVM with some restrictions. (for now the built-in app only supports Debian)
