Update: Apparently the Samsung Galaxy S does support “HD Voice” (which Samsung refers to by its proper name, WB-AMR). Activate it through the service menu by dialing *#*#197328640#*#* from the phone dial, then select 5-Audio then 7-WB-AMR, and turn it on. If you have a SGS 2 on Telstra, let us know if this feature works for you.
Telstra today announced the introduction of HD Voice calling on their NextG network. What this is, is clearer voice calls on some newer devices thanks to some great new(ish) technology that allows a greater frequency of audio which in turn picks of your voice much clearer and can reduce background noise in the process. For a video of how that works you can hit the break.
But what caught our attention is that out of the 5 devices that Telstra says supports HD Voice calling out of the gate there is only one Android device, the HTC Desire S. This will of course be a great new selling point for Telstra, giving them a greater advantage over the other carriers. The Big T also noted that the upcoming Sony Ericsson Xperia Neo will also fully support HD Voice calling, but made no mention of the Galaxy S II. Interesting. Hit the break for the video of how HD Voice works.
