When I answer or make a phone call, people can't hear what I'm saying. Its like the microphone is off. If I turn on and off the speakerphone then the regular microphone will work fine.. It only does it at the start of a phone call. Please help

P.S. I've also tried it with no protective case on the phone. Sometimes the call works, sometimes not. You get the picture.

P.P.S. I think it is something to do with the volume control because about half of the time, the person on the other end can hear me if I yell. They say it is still very soft and tinny, as if I am far away in a tin drum and sometimes, total silence (as if muted).

No

I sent a longer reply to this yesterday but it didn't get posted about what steps were suggested to me.

Our filter might have picked something up. So it's not the mic itself not working properly, but something where it's in that specific call mode. I'm going to see what I can find out about how that software changes when between those two modes. If it was physically the mic, it wouldn't pick it up at all while in speaker mode.

I very much look forward to anything you can find out.  Thank you
