If I switch off wifi of my phone mid call, it drops 20+ frames. That isn't exactly seamless. It's far worse if I just walk out of range

Hmmm, I don't know what's different in your case. For me it switches very seamlessly if I walk out of wifi range. No dropped frames. I haven't tried manually switching off the wifi though.
