Wrong elevation data recorded
Description
I have a Xiaomi 11T Pro smartphone with GPXViewer PRO 1.44.1. I have noticed that in this version and also in previous ones the recorded altitude data for some minutes are totatiy crazy; suddenly the altitude changes up to 500 meters. See attached image (bottom part) please. By the way I disabled "Elevation from air pressure" setup parameter.

Hello,
