Doesn’t require root, installed on top of Android, launches like an app.
Best, lowest risk way to get familiar with the capabilities without requiring a new device with specific distro support. I’m a huge believer in having things you can actually experience in your hands.
Mobile distros:
- Mobian (aims to mainline into Debian)
- Droidian
- Maemo Leste
- Postmarket (based on Alpine)
- Manjaro (based on Arch)
- Ubuntu Touch
- Pocket Blue (Fedora-based)
- Others
Mobile desktop environments options to try on your distro:
- Phosh (Gnome-based)
- Plasma Mobile
- Lomiri
- GNOME (mobile) Shell
You could even try installing Waydroid in it for Xzibit-style Android-ception
Is it possible to dual boot my device and keep the Android isolated while being able to run Linux in other partition?
I’m sure it’s possible, but you’d need a device specifically supported by the distro, you’d probably need a custom bootloader, among other things that make it not as easy as doing dual-boot on a less locked down device. It’s probably harder on purpose by Google.
