I first noticed these issues 6-9mos ago. No new buildings. Movements of 100 feet or less can make a difference within buildings.

While I realize the in-building service is often more variable, my primary concern is that voice coverage now with VoLTE is so much worse than it is with CDMA. My sister in CT reports similar issues. It is not restricted to in-building coverage. I hope it improves soon because it's basically a deal breaker for us and most of my friends, etc.
