Last Friday, the mic on my Galaxy Nexus stopped working. Mostly. Still works in speakerphone mode, but not in handset mode and it doesn't work for voice dialing or any other voice entry. Bluetooth works fine, but I don't always have a bluetooth headset with me and I don't always want to be on speakerphone. Searching for similar problems yielded several inconsistent hits. Didn't load any new apps either Friday or a couple of days before. Tried power down/pulled the battery for 10 minutes, no change. Any suggestions? Sound like SW or HW? My assumption would be SW since the mic works in speakerphone mode, but that's just a guess...
