[Cellist]

I was in a rehearsal last week and had accidentally left my wifi on on my tablet (I had just downloaded some music into MS pro prior to the rehearsal). While playing suddenly google hangouts took over the screen: someone a friend wanted to have a video chat. I laughed about it, told myself to always remember to turn off the wifi, but I would think that hangouts or Skype (no idea if that can "break in" also) should not be able to be activated when MS is open.
