Firs time today I noticed... [HD] next to the person that called me just now?
And the call was ALOT clearer.. what happened? I'm on Android N Developer preview and haven't updated anything lately..

depending on your phone, it may be part of the "next gen voice calls" initiative. (http://www.theverge.com/2016/4/6/11378394/t-mobile-announces-evs-next-gen-voice-calls-galaxy-s7-lg-g5)
i've been getting HD calls to everyone regardless of network and it's been much clearer than with the iPhone i had up until this phone.
prior to this phone (which i just got a few days ago), i only got HD when calling other T-Mobile phones.

EVS is not something that is on the android nexus phones. I am assuming @OP has a nexus because they are on an Android N Develop build. Most likely it is the 'regular' HD voice with another slightly newer phone that's come out within the last year or so.

T-Mobile to T-Mobile calls where both callers are using VoLTE and/or HSPA results in HD calling between parties. Calls to other and from other networks do not.
Ah ok thank you :)
if he has the s7 or G5, all calls will now be in "HD"
