Hi @Anders_ASUS , regarding my previous threads https://zentalk.asus.com/en/discussion/44822/no-hd-voice-in-3g-calls-amr-wb-codec#latest
and https://zentalk.asus.com/en/discussion/41828/hd-calls-in-3g-not-working#latest
I was looking at the ZF 8 forum and saw that there is now VoLTE support for several carriers in Spain for that model. It looks like finally Asus has taken steps about VoLTE (t-mobile USA on zf 6 also, etc). As probably the same profiles would be valid as the chipsets are qualcomm in both phones....Is there any chance that it could be implemented for ZF6 also?
Also from some people messages in the ZF8 forum, I see the "no HD in 3g" problem has been carried over to the zf8 😂... I can understand VoLTE, but not having 3g HD is frankly ridiculous
