Nexus 5. Located AB. Today, I started having a problem with this phone and it is only a month or so old. All the sound works. I can hear youtube...I can hear my phone ringing...I can hear voicemail messages...But I can NOT hear the person at the end of the line. You can hear them very very faintly - not enough for a conversation. So what's up with that? Again - I can hear sound just fine for other things but the person on the other end is too faint to have a conversation with them. They say they can hear me just fine. Help!
