Ever since I have the phone (when it came out) I see the dialer screen saying attempting HD voice but it never does... I used to be able to with the Galaxy Note 4 So I'm wondering if it is not activated on our V20's or it's just my phone?
Signal strength shouldn't be an issue because I usually make or receive calls at home or work just as I did with the Note 4 so it should be the same.
I'd like to see some opinions or perhaps answers from the community or LG V20 users...
Yes the V20 supports Sprint HD voice for Sprint>Sprint voice calls to another user with an HD voice capable device. HD voice will not work if you are not calling an HD voice capable phone. HD voice will not work if you call someone on another carrier.
If you have Wi-Fi calling enabled, HD voice may not work over CDMA, but should work on a Wi-Fi call.
