can't hear when making or getting phone calls. but the other end can hear. if put on speaker, i can hear but the other end cannot. HTC is no help, the Verizon store tried to help but still stuck with this phone that stopped working properly after 3 months. haven't been able to make a phone call since July or earlier. looking for help with this issue. my last option is to stop paying my bill to force them to help me.
