Iphone XR can't answer a call

[carguy1949]

When I try to answer an incoming call I slide the bar to answer and the call disconnects. I have to call the person back. Happens over 50% of the time. I have all the latest updates.

Sounds like the WiFi calling issue, check the thread on that topic. It is a long ongoing issue with Xfinity mobile. Nothing wrong with your phone.
