Q1561573600169, Jul 19, 2019 : This is a strange issue. When i talk on calls lying down (without using earphones), the other caller is unable to get my voice properly. As soon as i get up and sit or walk, and talk, my voice gets clear. There’s no issue while using earphones. But i am unable to converse while lying down on bed. Its something like, mic is not working when phone is in that particular position or direction.
