The customer needs to activate GPS mode before the start of any activity from the toggle button from the activity list. The watch will look for the GPS signal and the strength of the GPS signal will be shown on the watch itself. When the signal strength is good, the signal bar will be in green and when the signal is low, it will be in red. Once the signal is green, the customer needs to start the activity. After finishing the activity, the detailed GPS data (Track, Direction, etc) and other activity-related data will be shown in the app interface.
