I've found and downloaded Modul 04 LibreOffice Writer and Modul 05 LibreOffice Calc from the Play Store for my Galaxy S4. Problem is they either can't open files I'd created on the desktop PC or I don't know how to [make] them do so. Either is possible. :-(
These appear to be from some foreign developer but I thought I might be able to use them. Anybody know of a solution or is there another app that will do the job for me?
