Does Mi5S support HD voice (AMR-WB voice codec during a call in 3G networks)?

I have 8.5.3.0 global, and 8.0.3.0 before, and never experienced HD-voice calls.
Although HD-voice worked with xperia and iphone within same network.

Not sure, but probably not. Would guess the phone would cost abit more if it had the function.

Oh, this mi5S have a top chipset and everything, so that it would be strange if it does not support such purely software based (as I guess) feature. Moreover it supports VoLTE (although I did not experienced this either) which utilizes same voice codec (I guess). Also mi5/s/plus are in the supported list in wikipedia: https://en.wikipedia.org/wiki/List_of_smartphones_with_HD_Voice_support. Maybe it is supported on some Android 7 based ROM?

You might need to call your provider to enable it for your mobile. Some features can be disabled by the operator if they don't know the mobile.

You think the operator will adapt his network because some Pepsodent asked for hd voice?

Yes, some do. Maybe they have a whitelist of tested devices for which the function is enabled or it's even a number based feature which can manually be enabled.

Apparently this does not deal with the network provider. There is no AMR-WB in mi5s global ROM.
Did anyone try the latest MIUI 9 developer ROM? Does it support HD Voice?
