Linux phone. UI is very good there.

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.

Newsflash is the best from all I tested and even works nice on mobile.

/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.
