Yes, I have been having the same problem.
The problem seemed to start after the latest Firmware update that brought the WiFi Calling feature.
It seems that the GPS problems are being caused by the WiFi Calling feature. My personal belief is that it is the Location Verification part of the WiFi Calling feature that is causing the problem.
For me, rebooting does not resolve the problem. The only thing that works for me is to completely shut down the phone for a minute or so, and then restart it.
I hope that the bug is fixed sometime soon. Until then, however, I will just keep shutting down the phone, and restarting it when I have the problem.
