I am basing my info on fact, not feeling. You need two working phones that support HD. The S5 displays if HD is working. It did not display when I tried all radio combos. I also tried the sine wave on some of the radios with nothing to report. If someone can report that the 2nd device they are testing has an HD indicator, and it does work, we can have a conversation.

maybe the s5 can't tell if its connected to a HD call with a nexus? I have a s4 as well as a n5. Samsung has some really crappy software for sure.

One of the reps in the store had an IPhone 5S and and it worked, so the only other reliable test is the sine wave.

I think T-Mobile US needs sipXtapi for HD voice.

Talking More Toys to Play With

All of this talk about HD, now I want to try it out too even though I hardly make phone calls anymore...

Just like the whole 4K TV craze and 1440 x 2560 display resolution on phones...

Nexus 4 does not support HD Voice in hardware. It had a software support for HD Voice till 4.3 , then it was droped.
So, unfortunately, you will get no HD Voice on Nexus 4 with kitkat.

According to anandtech nexus 4 supports hd voice however it isn't on the T-Mobile whitelist. The nexus 5 however is.

From the link:

" I’m actually very impressed with how well the Nexus 5 performed at rejecting noise using the normal babble distractor track I use. In addition this was a T-Mobile AMR-WB “HD Voice” call between two Nexus 5s, illustrating that the Nexus 5 is indeed in the T-Mobile whitelist for HD Voice.



As an aside, the Nexus 4 oddly enough still hasn’t been green lit for HD Voice on T-Mobile, and given its age probably never will at this point, although the hardware is entirely capable."
