Qubes can mount Android 2.x devices with no problem as external USB devices, but isn’t dealing so well with Android 4.x devices - as now MTP or PPTP modes are the only options. I’ve seen blog posts suggesting installing simple-mtpfs (in the template? in Dom0?) to allow for mounting an Android 4.x device as an external hard drive but would like to get your input on the canonical way of doing this.
Currently the Android 4.x device is recognised as a USB device but not as a block device, hence is not made available to AppVMs for mounting.
