No VoLTE or no showing of an VoLTE icon in the status bar with O2/Telefonica Germany

[Ratnakara]

There is a bug in the newest firmware 45.0.A.7.120 for the XZP (customized/non branded Germany)

VoLTE does not work (although i have the feeling it works from time to time because the connection/dialing time was very fast in those cases) or at least, the VoLTE icon never shows up. LTE signal reception is very good in my region and Wifi call works just fine.

As a side note: Provider is O2 and the sim card works flawlessly in both modi VoWifi and VoLTE with the Galaxy S7 Edge (O2 branding).

Any ideas folks/support staff?

Many thanks in advance for your feedback

My volte icon never shows but in the quick menu shows as active, I know it also is working as when I make a call, the signal stays on lte instead of dropping down to H/H+ 

As I'm on O2 UK, I suspect it's something they haven't added their end on the firmware additions. Interestingly though, I do get the WiFi calling icon fine.

Thank you for your feedback/confirmation. I'm quite sure VoLTE works with the XZP and and the no-show of the VoLTE icon/symbol is just a small bug.
