In my house it shows 0 satellites, while my wife LG G7 shows 6 satellites; I expect it is similar in the woods.
How would you expect the Pixel 3 to be?
(out in the open the G5 GPS works reasonably well, but even then it gets half as many satellites as the G7)
Also, the Pixel 3 is new, but they apparently haven’t been made in years, so the battery is a few years old. Can I expect normal life out of it, or will it soon die?
