I can confirm the same issue on my Galaxy S24 Ultra.
It started yesterday. When at home, I have 4/5 bars on Verizons 5G network. Prior to yesterday I've not had this issue, but any phone call I tried to make (or any inbound call I tried to answer) gets dropped as my service suddenly goes to . Within seconds of the call dropping, my phone finds service again and is fully functional via text or internet. But the issue persists with calls until I drive away from my house.
I've tried basic troubleshooting to reset my network and device. nothing seemed to work. Today, I was just about to call customer service after about 15 minutes of no success and the issue went away seemingly on its own (for now). I would love to know what could cause this type of issue as there doesn't seem to be any good answer from Verizon out there. And I want to avoid it happening again in the future.
