Connecting to Windows 8.1 phone from Linux Ubuntu

Question

I am trying to connect to a Lumia 435 Windows 8.1 phone from Ubuntu.

It is an mtp device, and when I connect it to the computer, it gets mounted on Nautilus. I am even able to create directories in the phone and move files into these directories, which are visible from the phone. However, I can't read files that were previously there, or files that I copied into it in a previous session.

What's wrong here?

UPDATE: in the meantime I installed an FTP server app on the phone, and I am having no problem anymore transferring files in both directions. Accessing the phone directly would still be interesting, but not essential, at least for me.

Answer 1

I am also affected from this bug (I suppose it's something Canonical would have to investigate) on my Lumia 1020 using Windows Phone 8.1 Update 1. What I figured out is that when you remove the USB Cable that you use to connect your phone to your computer, after of course "safely ejecting" the device from Ubuntu, and re-plug it in, it will recognize all files and folders correctly. Finally, it seems to me as a sheer coincidence that I also use Ubuntu 15.10...

Edit 1: Actually, what I think is happening is that Ubuntu won't refresh the contents of a folder it has seen before on the phone. Watch out whether you can open a phone photo directly from double-clicking its icon on Ubuntu. My Ubuntu will display "error: the file couldn't be opened".
