Loudspeaker mic issues - Sometimes I cannot be heard clearly. S6 Edge

[AC Question]

Not through-out all the call but at times people complain I either sound in a bad reception area or my mic goes quiet then back to normal volume. I often have the phone on loudspeaker whilst at home, The phone sits on my desk just in front of me so it isn't a distance issue. Sometimes I receive no complaint at all just frustrating when I do!!!

Welcome to Android Central! Is the phone in a case? Make sure neither of the mic openings are blocked (i.e., the primary mic near your mouth, and the secondary/noise-cancelling mic, typically at the top of the phone).
