Description of the specific icons on the watch during the activity

: Activity tracking in progress;

: The phone's GPS signals are insufficient;

: The phone's GPS signals are active.

These two similar icons distinguish whether the GPS signal is active or lost. If the GPS signal is lost, the activity tracker cannot save the coordinates.

If the GPS signal is lost, it is recommended to stop and wait a few minutes for the signal to return. But according to the location (e.g.: in an enclosed valley or near steep slopes), there is no point waiting for this signal to return; in this case it is preferable to continue on the route.

Note:
These icons are only visible in the top left of the watch screen when it is locked.
