Notes :
Add udev rules to make your phone (or others Android devices) viewed by NAS on plug in USB
Required you unlock your device and use a USB data transfert cable
Actually files are only accessible over SSH (not sure it is a bug from the photofs mounting)
on some NAS it mounts gphotofs in /share/mtp_external (ts-253A , TS-251+ ) and some others /share/external/yourdevice (TVS-473)
