I got a new Android last week (Samsung A70) and installed v9 without a
hitch. I used package manager to update/install everything before I
attempted to use plot but plot just works for me.

On Android, the default display option is to generate a PDF and then trust
the operating system to launch an appropriate viewer. Are you sure that you
have a PDF viewer installed?

mine:
