I was ripping my hair out with this one. All the suggestions above not
working for me. Phone is Samsung S5.
ID 04e8:6860 Samsung Electronics Co., Ltd Galaxy (MTP)
So I tried (from terminal) "killall nautilus", then restarted it (by
clicking on file icon). "Samsung ANDROID" now shows up in nautilus.
Click it, and a dialog comes up on my phone with the title "Allow access
to device data" and message "An MTP connection will be established to
access the data on the connected device." Press "Allow" on the phone, it
then works as expected.
Under windows, there is no secondary step to allow MTP transfers on the
phone, which makes using it in Ubuntu, non trivial and inconvenient.
I realise this doesn't actually solve the problem, but this bug has
considerable heat, and it may be of use to others.
