Yes. I have 2 LG G3s with Verizon, got the update to Advance Calling last week. Installed on both phones. The sound quality is definitely better. It is much clearer, and you can hear more details. My wife and I did notice a difference. Also, you can do video calls right from the phone dialer, either one-way or 2-way. Video looks good, but of course it depends on the signal quality. The only thing I am not sure about is whether if you use video calls, if they count against your data.
