Hello, I'm listening to music with my GS4 in my pocket and iPod earbuds. I stop the music for a minute to talk to someone (by pressing the center button on the earbuds) and then press the button again...but it takes 20-30 seconds before the music starts playing. If I pause the music for just 10 seconds, then it starts-up right away. Any ideas on why this delay happens and how to fix it? Also, I like to have music controls on the lock screen, but when I enable this, the buttons inevitably get triggered while the GS4 is in my pocket. Any ideas how to get around this issue (besides not having lock-screen controls)?
