I have a recently purchased Samsung Galaxy S5 and am just "learning the ropes" of smartphones. The problem at the moment is that I cannot display GPS coordinates in Google Maps,and cannot download the app ("latitude and longitude coordinates") that is supposed to provide that service - and for that matter I can also not download the Google Maps upgrade. Yes I do have a Google account and a gmail address. When I try to download an app from the Play Store (nomen est omen???) I get the circling worm ... and two hours later the worm is still circling and I still don't have the app.
Google Maps immediately shows me my present location, marked on a map or more usually a Google Earth street view, but I cannot display the GPS coordinates, which I need to locate work sites sent me by USA ("call before you dig" - I am GM of a local water authority and need to be sure that proposed excavations are not going to hit any of our water lines). I can locate the sites very approximately using my ancient Magellan GPS unit, but either the Magellan or USA is pretty inaccurate. It gets me into the vicinity,so I can then scour around and find the USA marks, but that is time consuming. The GPS in the Galaxy S5 is very fast and seems to be accurate - but I cannot get it to display coordinates.
FWIW the phone is on T-Mobile, I have long had a T-Mobile account which was upgraded for this phone, and I have WiFi at home and in the office, and the phone is connected to either of those when I am within range. Current account settiings are unlimited voice, text and data.
I have to suppose I am doing something wrong, but what?
