I’m actually happy with Ubuntu. It is very stable and if you install Flatpak, you have another world of high quality apps to use.
Linux phone. UI is very good there.
/media is for removable drives. If you mount something there, file managers like Gnome will show you the “eject” or “disconnect” button.
/mnt drives show up as regular network drives without that “eject” functionality.
Newsflash is the best from all I tested and even works nice on mobile.
