Wifi Calling

[matty032]

----- ADB INSTRUCTIONS -----
Enable ADB Debugging Mode in Developer options

Plug your phone in.

On your desktop, go to the command prompt and change directory into where you keep ADB.exe

If you have never connected your phone to adb, you'll have to allow it. Type adb shell and you'll notice a pop-up on your phone screen that asks for permission. Click yes and try the adb shell command again.

Then type this

settings put global wfc_ims_mode 2
Press enter.

For pros:
adb shell settings put global wfc_ims_mode 2

Look at your wireless settings (more menu) and you'll see that WiFi Preferred is active

Don't forget to toggle airplane mode and, it should be set to go. It persisted through a reboot, it will be interesting to see what else it persists through.

I cannot claim this as mine. It came from another user on XDA. Works like a charm though. It kept Wi-Fi preferred even after upgrading to DP4.
