Bug 325924

Thanks for the bug report.

The status bar uses KDiskFreeSpaceInfo from kdelibs/kio to determine the free space. It seems that it cannot handle MTP devices though, and I'm not sure if it could be modified such that it could.

Probably one would need a generic way to ask kioslaves (kile kio_mtp) for the "free space", but AFAIK, such a thing does not exist (yet).

In any case, if I'm not mistaken, there is no way to implement this in Dolphin without support from KIO, so I'll reassign this report.

really kio-mtp crashes in dolphin when trying to connect to a device, even UBUNTU-Phone (p.ex. BQ-Aquaris 4.5).
!! my Interim-solution:
install nautilus + gnome-icon-theme-symbolic 
starting with nautilus i can connect to the device and get data.
not tested (i will test these days): 
to rename or to move a file.
to connect a android 6.x.
-->so, i think the problem is in dolphin.
