Last updated
Ubuntu Touch runs an image based system with Android hardware adaptation underneath. The phone holds the rootfs, user home, and click apps. Updates arrive per channel like stable versus devel.
Same device codename means same images. Exact cache paths shift with focal versus noble bases. Keep battery high during flashes. If the installer stalls, check USB drivers and cable first. App data restores vary, so export contacts and notes to files as well. Screenshots of settings help when support asks for reproduction steps later.
