Geotag photos

Hi all,

I try to add a geotag to the photos we make. I activated the geolocation in the camera that ODK collect uses, but for one reason or another, the photos don't have a geotag when I download them with briefcase. At the same time, the photo's do have a geotag when I take them directly with the camera (so without using ODK collect). Any ideas what could be the problem...? Thanks.
