Why are the Elevation, Max. Elevation and Incline values not always accurate on my Kiox 300/Kiox 500?

Kiox 300/Kiox 500 retrieves elevation data from the connected smartphone. Various factors, such as the sensor in your smartphone or external factors such as weather conditions, can affect the accuracy of the values. If a barometric altimeter is integrated in your smartphone, the values are usually more reliable and accurate than in smartphones without a barometric altimeter, where GPS is used to determine the elevation.
