Simple question.

[jericho375]

How do you select your primary Input. (as in, how do you make your Primary mic the default mic?" I am using a galaxy nexus running on Android 4.3, I have spent numerous hours researching this and it seems I am the first to ask this question.... so certainly it must be a simple Settings > ? > select primary Input. but I have checked every option in setting and could not locate it (even developer options!). please respond for I cannot make calls, however I can use other apps with my primary mic...
