If there is a thread already explaining please point me that way but iv already tried using base app of Google maps and using many apps to calibrate to no avail even did a factory data reset still the same thing PLEASE HELP I have to have gps working on my phone for traveling.

You may have to pull the SIM to do this - some SIMs (like AT&T's) disable this service menu. This rebuilds the GPS drivers from NV (nonvolatile) memory. It helped a LOT for me last year when my AT&T Note 4 started doing some seriously wonky things with the GPS. Your mileage may vary (see what I did there?).



Dial USSD code *#0011# (basically "call" this number using your phone dialer)

Then do the following:

Menu/Back
Menu/Key i.nput, enter Q
Menu/Key input, enter 0000

Wait a few seconds and a service menu should come up.

From the SERVICE MODE menu
