iPhone 5C behaving like headphones are plugged in 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?
Try plugging in a headset and unplugging.
