I have been to multiple Verizon sales/techs to ask for help with the echo which anyone I call says they hear when I call on my LG G5. It does not matter what cell provider they have or if it's a landline. They hear their words repeated back to them. All these techs say there's nothing to be done, "it's just something that happens with some phones". Really? This is how far we've come. I have done every trick they've recommended including making sure Talk Back is off and nothing helps. Is there nothing else?
