Just got the Z6TV last week and I am experiencing the same problem with mine. If that is the way this phone works I think I will return it. Does anyone know if Verizon will also let me revert back a month by month contract if I were to return my phone before the 30-day trial?
I really like this phone with the exception of this annoying back feed of your own voice. Please help!
I found out this is a feature on every phone. What I found out was if I put a piece of tape over the small hole you find at the bottom of the phone, it'll block out this echo. Try it to see if it's tolerable.
