If you're not able to access GPS or location info, please do the following:
1. Verify if the course you selected is GPS-enabled.
You can do this by checking to see if the course you are playing has a GPS icon in its listing or profile. If it does, then proceed to step #2. If it doesn't, then this course has not yet been mapped for GPS functionality.
2. Verify to see if "Locations services" and "Foursum GPS" are toggled to "ON" position on your device.
Step 1 - Open "Settings"
Step 2 - Select "Privacy"
Step 3 - Select "Location Services"
Step 4 - Make sure "Location Services" is set to "ON"
Scroll through the list of apps, and look for "Foursum"
Make sure "Foursum" is set to "ON"
