Samsung galaxy m51- when I make a call to someone from m51 only my voice can be heard ( when i am holding the phone), voice of people sitting near me is not heard properly for person on other end of the vall. So basically the voice of the person holding the phone can only be heard.
i was facing the same kinda problem but i actually i found out this was not an issue with the phone..i got my phone laminated once i bought it ..but there is a small hole on the top of the phone and one on the bottom near charging port ..the guy who laminated didn’t uncover those holes. now i did it myself ..now the loudspeaker mode is working fine..you can check once if you got your phone laminated.
