Hi Guys Ive had my Tattoo phone now for over a year and its been great until recently whereby on making or receiving a call the phone just goes silent but is still connected the other end but they cant hear me and i cant hear them. If i hang up you can then ring them back it connects as normal but same fault. Only way of clearing it is to remove the battery?!! Its been back to HTC via Vodafone for repair but its still happening? Anyone else have this fault?
