Hi, I use a LG VX6000. Recently, I found that the phone was unable to transmit or receive audio (key beeps, phone calls) except through the earpiece attachment. The ringer still works as normal, however. I didn't make any changes to the phone's configuration prior to the issue beginning, and a cold reboot of the phone didn't help. Is there anything else I could do to restore the phone to normal functionality, and not have to depend on the earpiece? Thanks.
