Two phones in the same rucsac, one recording a continuous track (OSMand) the other taking occasional photos.
The photos are the small orange square on the map. You can see that about half the time the photo camera locations are on the track, but nealry half of them are up to 30m away.
Camera apps are not to be trusted to get accurate locations! In this case the photos can use the timestamp on the photo to get an accurate location from the track, but this is too much faff for most people.
