My iphone is not set on silent, but calls, text, games and even key clicks have no sound. Turned power off, reset all settings. Nothing. can't answer calls, becasue I can't hear my phone ring! Help?
If you are getting sound on headphones only then the problem is probably with the headphone sensor. Try blowing hard on the headphone jack and inserting your headphones multiple times to see if you can dislodge possible debris blocking the sensor (making it think your headphones are always plugged in).
