Why won't my S2 play videos?

[AC Question]

I'm trying to play videos, they start, but screen remains black. i have waited up to 10 minutes, and still no luck. Could my tab s2 have a virus?
This started about a week ago.

Re: my s2 will not play video

Welcome to Android Central! Where are you playing the videos from? Are they downloaded from somewhere, or streaming?
