I use sysutils/simple-mtpfs to mount the android device.
when I mount the phone through USB this is the relevant section:
/dev/fuse                                   356311 78912 277398    22%
/mnt

That's the most complicated mount process that I use,
for the ssd it's just a simple mount /dev/device /mnt
relevant output:
/dev/da0                                    923913 121450 728550    14%
/mnt

Can you tell me what information you're looking for so that I can gather it
all up and send it.

@Jon Brawn
I am running current because I handle admin a few other boxes that are on
RELEASE so I have
to run in current to make sure they don't have it.
I do wonder about those locks as well but, they should only affect the
multiple small files,
not so much the larger files.

The microsd card is physically inside the phone.
