Twice now this has happened. I've been on my phone whether on Facebook or reading a page on the Internet and all of a sudden music starts playing by itself without any music apps being open, this time I opened up the phone app as to make a call and it stopped then I closed it and it started again, so I do the same open phone app and it stops... Closed the app and it's ok now....it's really strange why it's doing this, I've had the phone for 3 weeks now and it's happened twice... Has anyone else had this?
