This issue with wifi variant table. If you have LTE or 5G variant then you will not face this issue.

Vo to pata hai but S series k phone mai pahale se by default hai because ye flagship smartphone hote hai. Kabhi apne jankar se kisi noise vali jagah se earphones se bat karna uske bad direct phone se fir samne vale se poochana different.

Voice focus mean?

Right i am also frustrated

Right brother
