MTP, andoid 3+, Jessie KDE file transfer
By default, in a Debian Jessie (testing) with KDE, any MTP device is connected as a camera device. So for write support on the media, it's required to install KDE MTP KIO Slave and edit a file.
apt-get update && apt-get upgrade && apt-get install kio-mtp nano /usr/share/kde4/apps/solid/actions/solid_mtp.desktop
In nano: Replace Exec=kioclient exec mtp:udi=%i/ By Exec=dolphin "mtp:/" Ctrl + o for write the file Ctrl + x for quit
Just verify the device isn't in sleep mode or protected by password, re-plug. It's now possible to mount the media for any KDE application would be able read/write files on the device.
