One of my daughters has a galaxy s3 mini, hardly picks it up from one week to the next but having borrowed it for a few days I notice that the receiver speaker doesn't seem to work. Meaning when someone calls me or I call them, they can hear me, but I can't hear them. If I press hands free it works fine. Tried the star hash zero hash zero to test the settings and on,y one that doesn't work is the receiver one? Any help as always appreciated.
