Purchased SGP 4.2 to dip my toe into the Android world, and having a weird problem. I put in an external media card and downloaded my mp3 and playlist files from my PC. I use the pre-loaded music player app to listen to my playlists, and it works pretty well. I then use the Active Applications widget to exit out of the music app. 5 or 15 minutes later, with the player sitting on my desk, nobody near it, it will start playing a random song. Help an old guy out!
