OK but if you still don’t control the device ala unlocked bootloader, it’s still a google-owned device. (yes I know that’s not totally accurate but the point should be obvious)
A terminal app? I still have an android 2.2 tablet with a terminal app. Wow I guess?
It’s not a terminal app. It’s a full Linux ARM VM. Poor naming scheme, but hey, it’s something.
They added support for running a VM with an actual Linux kernel and distribution: https://www.androidauthority.com/android-linux-terminal-app-3489887/
Does it support a desktop and video out through usb-c?
On GrapheneOS this is a supported option, it has desktop mode on Pixels 8 and up. I think android phones on android 16 and up support this too as long as they have the hardware support for video out over USB C
