I keep missing some calls because my phone does not ring (ringtone does not sound). Sometimes it rings, sometimes not. I missed a very important callback today and I don't feel like waiting 45 minutes on hold to contact the caller.
I use WiFi calling because I am in an area with mediocre network coverage. I thought of turning off WiFi calling but other users complaining of the same problem don't use it, so I don't think that's the issue. Plus if I turn it off then my reception is even worse.
One suggestion is to reboot my phone. The last time I missed a call I did that, and then my phone did ring afterward, but I have no idea if this was a solution or a coincidence. Anyway, I am missing calls and rebooting my phone every few hours in the hope that I will stop missing calls is not a real solution.
A couple of years ago this happened on another phone (Samsung Galaxy S20) and the agent suggested I reset network settings. This only helped temporarily and then the problem returned. Not to mention the nuisance of having to go in and re-enter all my network settings.
I'm currently using a Samsung Galaxy A23.
