My Verizon Pixel 4a 5G has a frustrating issue. While I am on a longer phone call, it sometimes mutes my end of the conversation. To be clear, the MUTE button is NOT activated. It is just the callers suddenly can't hear me even though I can hear them. When I look at my screen the phone call is not in the foreground. All I see is a little circle with the callers picture. If I click on the picture I get a drop down menu. One option is "Go back to call" When I click on that the other party can hear me again. the entire time this is going on, I can hear them. This always happens when I am holding my phone to my face but once again I am NOT accidently pushing the MUTE button because it is not activated. Is this a setting I need to change?
