hi there,
We have 2 Samsung s8 unlocked working pretty well... 3 days ago something strange happened, voice over wifi stopped working - we can still get ovice over LTE but not voice over wifi with the little phone icon.
I have tried every possible setting to no avail, restarted, airplane mode, toggle on and off both from Connections > Mobile Networks and the other one under Call > 3 dots > Settings > Wifi Calling and Wifi Preferred. nothing happens anymore.
also tried:
network reset on my phone
cleaned cache from boot menu
cleaned sim card plus checked all settings...
also tested with another wifi at my work and same story.
We didn't touch the software either. All it happened was a change in our wireless setup at home with new routers or something my landlord manages, but still does not justify why at my work doesn't work anymore as well.
Is anybody experiencing the same thing?
thanks
Gabrio
