Who I have the same questioned this topic

What is the solution to the Galaxy S20 dropping calls and person on the other end of the conversation not being able to hear me?  I have been back to the Verizon store at least 20 times since I got my phone November 2020.  They have tried several things to correct the issue, but nothing has helped. I now have an expensive useless phone and nobody at Verizon cares.  I have been a Verizon customer for almost 20 years and I cannot get a resolution to this issue. REALLY????
