I just got a Nokia Lumia 620 as a backup phone. I'd say I can mount my Nexus 4 reliably with Ubuntu via nautilus using gvfs-mtp. Users with Android devices like the Nexus 4 still get error messages on a regularly basis of the device not being able to mount, but replugging the device mostly fixes the issue.
However, the experience with the Lumia 620 is far worse (the desktop sometimes freezes) and the workaround I found to get the device to work very crude.
I was prompted with a apport-collector window when nautilus froze during testing and send a report (this happend twice), but it didn't take me to Launchpad to open a report. I can also seen no bug regarding that topic that I am subscribed to.
## Steps to reproduce:
1. Reboot (or cold boot) computer and phone. Login to computers destop and unlock the phone by entering PIN.
2. Plug the phone via USB into the computer. (Cable works with Nexus 4 or another Android device.) The phone will give a signal that it is connected to the computer.
3. Try to open the phone in Nautilus. My desktop either freezes (cold boot) here or nautilus hangs (reboot).
3.a) If nautilus hangs: Open a terminal with Ctrl+Alt+T and kill nautilus with xkill.
3.b) If your desktop froze: Go to a virtual terminal.
3.c) If you just get an error message: Open a terminal with Ctrl+Alt+T and go to step 4.
4. Execute 'mtp-detect' (from mtp-tools package) from terminal (either via Dektop or virtual terminal). If you get one of the following messages wait a few seconds and try again.
$ mtp-detect

5. Go to a virtual terminal and do 'sudo service lightdm restart'. Login again, you hear the phone reconnecting to your computer and should now be able to open your phone in nautilus seeing the phones internal storage and the SD card (if there is) als sub devices.
6. Unplug the phone from the computer and start with step 2 if you want to connect the phone again.
