Why can't I open PDF files on my Samsung S6?

[AC Question]

Can't open pdf files on Samsung S^

Have installed pdf reader app as well I have changed setting to no limit download size and auto download as previously suggested.

I end up always getting file size 0 or incompatible file message.

Welcome to Android Central! Is this only for PDF attachments on email? Or for any PDF you download from the web? I've been seeing a bunch of threads about problems with the former, primarily on Samsung devices.
