Hi iv updated my galaxy s4 to lollipop now when listening to music through Bluetooth headset or Bluetooth speaker goes of for a second ever 5 minutes never had this problem before update was on kitkat before anyone know how to fix this iv done 2 factory resets and still same and cleared cache twice
Not specifically this phone, but years ago I had a simular problem. I was listening to my music through the car radio during a long trip and every few minutes it cut out for a couple seconds, then back on. Back then I narrowed it to my phone searching for either new mail, facebook updates, or a WiFi signal. I think once I changed how often it searched for a WiFi signal and changed the search settings it was fine and never bothered me again. Hope that helps.
