That's unfortunate. Basically, without those google extensions, MTP can
only do full-file copies. It can read a file off the device or send a
file. It can't let you read a little bit of a file, or selectively
update part of a file. This makes it mechancially impossible to do any
incremental operations, as you'd need for rsync. It means you can't copy
files with non-gvfs applications, and you can't open files in
applications. You have to copy the files to your computer (using
Nautilus, Thunar, etc), do whatever you want to them, and then copy them
back (or delete them if you were just reading them). It's a miserable
experience, but it's all that MTP has to offer.

The google extensions allow for normal random I/O on files, which makes
life much easier - but Samsung insist on using their own MTP server
instead of the standard Android one.

Title:
  Can not copy files by cp from Samsung S5 Mini in GVFS in MTP mode

Status in “gvfs” package in Ubuntu:
  Invalid

Bug description:
  In terminal:
  jarnos@jarnos-OptiPlex-745:/run/user/1000/gvfs/mtp:host=%5Busb%3A002%2C013%5D/Card/DCIM/Camera$ ls -l 20141103_114415.jpg ; cp 20141103_114415.jpg ~/Desktop/
  -rw------- 1 jarnos jarnos 1205994 marra  3 11:44 20141103_114415.jpg
  cp: cannot open ‘20141103_114415.jpg’ for reading: Operation not supported

  But I can browse to the folder by Thunar or PCManFM and copy paste a
  file to ~/Desktop/. On the other hand I can not open the files even
  via those file managers.
