I've been trying to play music from my phone in my car but keep having problems with it. I have a jack in my car that I then plug into my headphone jack which has always worked perfectly with other mp3 players. With my phone though I keep getting S Voice popping up randomly as well as songs randomly changing when I move my phone. It can be sitting still and then all of a sudden s voice will pop up, then when I close it sometimes the song will change. I've tried it with two different music apps and the same thing happens. Any ideas to why this is happening?
