I have a FP4 and wifi calling has never fully functioned for me. I’ve read through numerous threads on this forum regarding this topic - various phones, OS versions, etc. Seems to be a common problem. I’m just posting here as this seems to be the most current thread on this topic.
My problem is not specific to 3.2 - I got my phone back in February 2025, with whatever OS version that was, and the problem has existed from day one… It is just plain unreliable: I can often hear the other party but they can’t hear me. Or, sometimes, it will totally drop the call…or I can’t hear them, but then suddenly I can hear them. I’ve had to totally turn off wifi calling on my phone because it is so unreliable - which is very unfortunate as I don’t have strong cell signal at my house. And the problem is not limited to my home wifi - same problem on other networks.
