Hi, I have problem with connect my Lumia 920 to KDE Distros. I hadn't this problem on Ubuntu, Xubuntu or Mint. Only on KDE distributions.

After connection in device notificator are 5 positions, 4 empty named and 1 Lumia 920.

When I try to open storage I've got this message:
"File or folder udi=/org/kde/solid/udev/sys/devicespci/0000:00/0000:00:12/usb1/1-4/ not exists."

Exploring don't work in Gwenview and Amarok too. Now I use Qlix to explore my files but this is not what I expect.

How can I fix that or will be fix in the near future?

Are you aware of which protocol is used by Windows Phone to make itself accessible to computers? Is it MTP by any chance?

Yest, it's MTP. Problem is with kio-mtp I think. On Unity, Gnome, Cinnamon, XFCE I can open this Smartphone without problem, but for me KDE is the best and I want to fix that somehow.

Unfortunately kio-mtp has problems with certain devices due to certain limitations with how MTP is implemented on some devices.
As a workaround I would suggest mounting it using "mount" and working with it from there.
