1. An electronic device comprising:
- a display;
an accelerometer;
a communication unit;
at least one processor; and
a memory storing instructions executable by the at least one processor to cause the electronic device to;
pair the electronic device with an external device configured to receive global positioning satellite (GPS) information,obtain, using the accelerometer, a first measurement associated with a movement of the electronic device over a first distances,receive, using the communication unit, a second measurement, detected by the external device based on the GPS information from the external device, corresponding to the movement of the electronic device over the first distance,while the electronic device is paired, calculate a correction parameter based on the first measurement and the second measurement, and display on the display the second measurement, andafter the electronic device is unpaired with the external device, obtain, using the accelerometer, a third measurement associated with a movement of the electronic device over a second distance and display a fourth measurement associated with the movement of the electronic device over the second distance,wherein the fourth measurement, associated with the movement of the electronic device over the second distance, is adjusted by result of applying the correction parameter on the third measurement.
