Who I have the same questioned this topic

I got a Samsung J3 V 3rd Gen three months ago, and about 60% of the time, when I get an incoming call, I can answer the call but there is silence.  The caller only hears the ringing stop, but cannot hear me, and I cannot hear them.  No matter how many times they call back there is no change. And if I call them, we can't hear each other either.  If I restart my phone, that sometimes (usually?) fixes it.  I have gone through the online troubleshooter with no success.  Seems like such a basic function...for a *phone*, I am surprised to have this issue.  (My daughter has the same phone, and this was happening to her also, but she got a replacement last week due to other issues, so I'm not sure if this is still happening to her.)  Any thoughts?
