How to get the best map from phone GPS data
1. TURN OFF WIFI
Google location services use WIFI to determine location to ensure your location is from GPS only, best to turn off WIFI
2. GPS does not work indoors, i.e. on treadmill or indoor hall
GPS connects to multiple satellites to triangulate a location, most accurate if the device has line of sight with the sky. Different brands and models have different GPS hardware which results in some devices performing better than others.
3. Ensure your phone does not go to sleep, or go into battery saving mode.
Most phones have some form of battery saving mode which forces apps to stop when running in the background. If the app is made to stop by the phone's operating system, it does not log your GPS data which results in an inaccurate map. We have recommended settings for popular brands below, please check that your phone is configured to ensure that GPS logging continues in the background.
