Device - Mi6 on Xiaomi.EU 9.2.4.
On official Xiaomi global builds, HD voice over 3G works fine after I input a special code *#*#86583#*#* and activate VoLTE trigger in Network settings (though VoLTE is a different technology, the same trigger is responsible for HD voice as well). In Xiaomi.EU firmware, HD voice does not work, whether I activate VoLTE or not.
So, is there any solution?
Regards.
