In my Gear Fit 2 web app, I'm using the code below to get lat/long.

navigator.geolocation.getCurrentPosition(successCallback, errorCallback);

For this code to work, GPS radio on my phone must be turned on.

How can I force my app to use the build-in GPS in Gear Fit 2? or at least check it first before the phone's GPS?

Thanks
