The very first fix takes indeed a very long time (several hours) even outside buildinbgs. I too thought gps did not work on my XA2 plus.
Once I’ve had a fix, following fixes were quicker (10 min) if you don’t move location while phone turned off.
For GPSInfo, which version ? With version 0.13-1, in parameters you can choose “show empty channels: no” then you get 0 satellites in view.
