at the bottom of my map, there's a "Your Location" at the bottom right of the map that one taps. Or it is a blue circle icon inside a solid white circle, also at the bottom right of the map. That's if "Location" is already turned on, which is in the 2nd panel of my phone's notifications screen that show the status of what's on and off on the phone.

If "Location" is off, then, tapping that icon at the bottom right of the map won't work, it will say some message like it can't determine your precise location, or it simply won't work, but it will say to tap here to turn Location on or somesuch. Sometimes that doesn't work, so one has to find the Location item on the notifications panel and tap that on.

That's exactly 100% of everything I know about GPS on phones. I'm not sure this is what you are looking for. Probably not judging what's been posted upthread. But maybe this is helpful for someone that uses Google Maps and gets lost (within cell signal) and wonders where they are.
