Add yet another user to the list...I have been monitoring this thread for months now, and haven’t seen any concrete resolution to what seems to be a widespread issue. My experience is the same, marginal cell signal at home and constant dropped calls via Wi-Fi. Lately, incoming calls don’t even ring, and then voicemails just pop up a half hour or more after the supposed call. It’s very apparent that the phone is not handling switching properly or prioritizing Wi-Fi calling over the cell signal. It tries over and over to grab a marginal cell signal instead of staying on the Wi-Fi connection, and loses the call most of the time. In addition, I do notice that many times, cellular data doesn’t switch when I leave a Wi-Fi area, forcing me to reboot in order to get cell data when not on a Wi-Fi signal.
