I got my pre-ordered Nexus 7 16GB (from Staples) on 7/16 and everything worked fine until today. I just tried using Google Now and it is not picking my voice. So I went to Evernote to record Voice memo and it is not picking up anything either. I did Factory reset and not solving my mic issue. I think the mic in my Nexus 7 died? Anyone else got mic issue?
