I get this when trying to open an email attachment (Maildroid is my email program) which is a PDF.
Opening PDF files stored on the device works fine so the association must be right.
It is a PITA because I often email PDFs for alternates to myself, before a trip.
There is no config for this that I can find, and the phone isn’t rooted so I can’t dig around a whole lot.
Many thanks for any pointers.
