[digiKam-users] Success in importing pictures from Android mobile phone

[Maik Qualmann]

In Gnome / Ubuntu systems, a GPhoto2 monitor program runs that occupies the 
USB port when a device is connected. Rapid Photo Downloader will probably 
terminate this service. You should achieve the same thing if you run something 
like this before starting digiKam: "systemctl –user stop gvfs-gphoto2-volume-
monitor"
