Hi Desinia, how is your solution working so far? Any updates or other viable solutions? I am having the same issue with my rooted Volt LS740 and just want to check out how others are dealing with this issue. Thanks.
My Nexus 7 32GB (2012) does the same thing. When in portrait mode, the tablet uses the top mic which works fine, but when in landscape mode it automatically switches to the side mic which produces static noise. You can test yours with Hi-Q MP3 app.
