Hi, I have a Mi11 with xiaomi.eu 21.1.13 and I do not see the HD badge when making or receiving voice calls under VOLTE.
I also have a Samsung with a work phone and here all seems fine.
I made some tests and seems the problem is the XIAOMI and not the SIM: if I put personal SIM into Samsung and work SIM into XIAOMI, if from Samsung I call XIAOMI and if from XIAOMI I call Samsung, the HD badge appears only on Samsung; if I put personal SIM into XIAMOI and work SIM into Samsung, if from Samsung I call XIAOMI and if from XIAOMI I call Samsung, the HD badge appears only on Samsung.
So it is obvious taht VOLTE is working fine on both work and personal SIMs, it's simply the XIAOMI that is not displaying the HD badge. Not sure now if it's a ROM issue or a device issue.
In any case, if on Mi11 I make a phone call the 4G remains active, wich still proves that VOLTE is working.
Any hint?
