Yesterday I made a little walk. Oruxmaps shows me 7.57 km in Statistics. I know that the track is longer because I made the same track some months ago. In Track-Details the correct distance is shown with 9.57 km.
In the afternoon I transferred the track to trainingstagebuch.org and in this application the correct distance is also shown: 9.57 km
Edit:
After a tour with my bike I had the same problem: Statistics 21,6 km, Track Details: 23,6 km.
It seems that the statistic is always 2km shorter.
I also stated that the GPS signal is lost two times! So I decided to switch back to Oruxmaps v6. Oruxmaps v7 is too buggy :evil:
Edit2:
The problem was by in smartphone (Redmi Note 3 pro). There was an option active that if the screen is off for 60s the cache will be deleted. I disabled this option and everything is fine :D
