For Android, i connect my phone via usb copy things to a temp folder and then have a small scrip that will archive the photos using timestamps in my nas. This is the heart of the script that goes through varios temp folders:
for i in $FROMD1 $FROMD2 $FROMD3
do
cd $WD
exiftool -d “%Y/%m/%d/%y_%m_%d_%H_%M_%S%%-c.%%e” “-Filename<DateTimeOriginal” $i
done
Can you please provide more info about your setup? I have an Ubuntu thinkpad and I have failed so far to use the fingerprint scanner
