While the OS may not directly include a PDF viewer, I've never seen or
even heard of an Android phone that didn't have a PDF app pre-installed.
Given the diversity of the Android ecosystem I suppose it's possible
such a phone exists. But I would imagine they're very rare.

Few do, at least enjoyably.
PDFs are great for the narrow subset of cases where preserving
consistency with printed page sizes makes sense.
In today's world, most PDF documents are read on screen rather than
printed. And with more than half of Internet use taking place on
phones, that means the annoyingly cumbersome process of scrolling
horizontally as you read every line.
Some day OSes will provide "Print to ePub" like they currently do with
"Print to PDF". And when they do they'll join the 21st century, defined
by a vast range of screen sizes, most of which are simply too narrow to
accommodate fixed page metrics comfortably.
To help move that along, I've been considering making an ePub library in
LC, for both reading and writing the format. It would be non-trivial,
but quite doable. The constraint now is time. I could schedule that
for late spring/early summer, if I could find funding between now and
then to cover expenses while I write it.
