my note 8 mic suddenly stopped working ...callers are getting a wind noise ..tried voice recorder same result.I can see many users are effected with issue some of them got issue fixed by blowing in to the bottom ports.taken it to the Samsung official...
This started happening all of a sudden after the last update .it is showing samsung core service consuming battery .morover I understand all new devices having overcharging protection, which stops charging one battery, is full.
