Hi there!
so.. I've had my samsung galaxy s4 active SGH-i537 for over a year now, and it suddenly started to buzz on its own! it's the same kind of sound the phone makes when you get a notification, but in this case no notifications are coming in!.even when I mute all sounds, the vibrating is still there. It's so annoying because the sound interrupts the music player and cuts off the songs in the middle.
I would really appreciate it if someone could help me out
