I used termux with su privileges (su) and used following commands (if you do not have root access, then use adb):
setprop persist.dbg.allow_ims_off 1
setprop persist.dbg.volte_avail_ovr 1
setprop persist.dbg.vt_avail_ovr 1
setprop persist.dbg.wfc_avail_ovr 1
setprop persist.sys.phh.ims.caf true
In options → network → sim card I have the option to set volte calling or wifi calling.
source: GitHub - khrj/volte-fix: Fixes Qualcomm VoLTE on all GSI Treble Roms
(XZ1 with telefonica)
I have XZ1 Compact (lilac) running my own uofficial Iodé 4.4 build
WiFi calling heading, and a setting with my operator name (EE) which says either ‘Off’ or, after clicking on it and turning ‘Use WiFi calling’ on, ‘Make and receive calls over WiFi’I did what you suggested @mbrum , specifically I installed the zip from the volte-fix repo using twrp.
After installing there is no sim available and no mobile network. So I had to uninstall it again. Bump.
This is on latest Iodé on an XZ1 (Poplar)
I did not install the patch, I only set the props.
that made the VoLTE switch in the network settings available.
But the phone still says “VoLTE not available” in the test menu (##4636##) and connection drops to 2g when calling
I can trigger a WIFI call when switching to flightmode and toggling wifi on.
No VoLTE though
I had to additionally flash some provider configs , according to VoLTE und VoWIFI im Congstar-Netz (Sony Xperia XZ1 Forum) (Could have to do with specific Congstar provider I am using)
Now it works ! Thanks all for the amazing help!
Seconding this request, I’m definitely interested in giving iode a go, but without VoWIFI calls at home won’t work so it’s definitely a requirement for me.
What’s the psychedelic easter egg?
What ever it depends on phone settings and network provider
