I was listening to a song on the tablet and then went back to the start page to do something else and all of a sudden I thought my song stopped playing but it hadn't. The sound muted itself.
Then I set up the tablet so I could view my facebook pictures on the tablet. As I was looking at them, I noticed it also showed some videos I uploaded to facebook so I wanted to see what they looked like on the tablet but there was no sound. I thought it was because they were from facebook but I checked the speaker and noticed the sound got muted again.
Why does this happen and is it suppose to happen?
