[Android Question]

Can't open any type of PDF document. Just says All apps that have been associated with this action have been turned off, blocked, or are not installed. Also it keeps popping up something on my screen evert now and then that looks to be as its trying to open a pdf document.

Well people tend not to reply when they don't have an answer. And if enough other people post questions (this section was a lot more visible before the revamp, and hence the post rate could be high) an unanswered one can drop down the list fast. Put those things together and yeah, it can happen.
