How can I get a good GPS signal?

Open your smartphone settings and check that the GPS function is enabled. It is also recommended to activate the “high precision” mode if your phone has it. Secondly, be sure to start the activity from a spot where you can see open skies and where you are unobstructed from buildings, trees, etc. If the problem persists, you may have to check or adjust the device's GPS function.
