I recently purchased a Lumia 920 and had problems with it. I gave it to Nokia for repair and they have now sent a new one. Everything looked fine up until I tried making a call. The call went through but I can't hear anything at all. Not even the dialler! When I put the phone on speaker then I can hear everything but from the handset nothing! Has anybody else had this problem? Anyone know how to fix it? Don't want to send the phone back in after just receiving it. I need it for my work :/
