My iphone 6 buzzes instead of rings
It's a periodic thing, but sometimes instead of playing my ringtone or sound from a video, my phone just buzzes. When it happens I try to hit the home button to make it stop (if I'm watching a video) but there are times it doesn't. I've tried restarting it (normal and a hard restart) - it's a hit and a miss if it is fixed for the next time.
