When I got the Nexus, my speakerphone worked just fine. Now, when I turn on the speakerphone, the mic does not pick up any sound. I can switch back to the regular phone and the mic works just fine. As soon as I put on the speakerphone, the mic cuts out. I tried a hard reset, turning the mute on/off, toggling the volume, and uninstalling several apps. After a hard reset, the speakerphone works for a bit, then cut out again. Anyone else experiencing this?
