I updated my 5c to iOS 9.3.2 and since then the phone has been behaving as though the headphone are plugged in.
Neither speaker nor microphone work normally when taking calls - I hear nothing and the caller cant hear me. But when I switch it to speaker during a call it works fine, and I can hear the ring tone. Sounds in apps like Spotify dont work either.
Of course I've turned the phone on and off again.
Would anyone know what I can do?
