Hello, I have a Samsung A21s and the microphone works fine. However, when I make phone calls I have to make them twice as on the first call the receiver cannot hear me at all. This wouldn't be a problem but when you're put in an 2 hour long queue just to find out they can't hear you is incredibly frustrating. You HAVE to connect with the receiver once to fix the issue.
This issue does not happen when receiving calls.

Any help? I've had this problem since 2019.
