[zognwxxq] Transferring files via USB cable on Android

Nexus 5x, Android 8.1.0, Ubuntu 16.04

Need USB-C to USB-A cable.

Enable Developer Mode.

Settings -> Developer Options -> Select USB Configuration -> MTP

It will automount at /run/user/NNNNN/gvfs .

It is good from a security standpoint that cable access is disabled when the phone is locked.
