In addition to measured GPS location information, a phone also displays the current location using network information (base station broadcast information, etc.) However, network information may not detect your location correctly, so when a CASIO app uses location information from a phone, part of the data may not be used. Because of this, the location information shown by the phone and the watch may not match.
When the watch is unable to communicate with a paired Android phone or when Activity is being used while the watch is paired with an iPhone,, CASIO apps use location information acquired from the watch's built-in GPS. Because of this, the phone location information may not match the location information of the watch.
