Following are the steps you can follow to help retrieve your location faster:
1) It is sometimes difficult to read location indoors and hence moving outdoor (in an open space) may help the device to obtain the location faster.
2) If you are on mobile network, turning wi-fi on (with or without internet) may help the device retrieve location faster. If you are already on a wi-fi, Turn it off and back on after 10 seconds.
3) Open the google maps app and see if you are able to obtain your location.
4) If the above points do not help, the location retriever of your device may have got stuck, restarting the device may help.
