the internal microphone on my lg optimus t has quit working. i can hear people when in call but no one can hear me. the mute is off and i have tried toggling between the two settings with no help. tried doing a master reset, tried a battery pull. nothing works. please please help in another way than saying i have to replace the microphone. if it comes down to it, i may do that. but i may just trash this phone and get another one. thank you guys
