Comment 3 for bug 1650394

My Android phone gives the options of Charging, File Transfer (mtp) or Photo Transfer (ptp) when the USB is plugged but I have not found a (gnome/gtk) file manager that can show thumbnails over mtp so I guess this is not implemented upstream (yet).

However, other filemanagers can launch the photos in a local photo viewer so I guess the "cannot open" message is no longer needed.

The Files project is not transferred to here: https://github.com/elementary/files

A new issue related to the opening of image files over mtp should be created.
