This is a setting issue cross different phones, even between Samsung 
phones, who is controlling the File Transfer (F/T).

To make things simpler, ignore who controls the F/T and repeat the same 
process twice with a umount in between.

#  jmtpfs -o allow_other /mnt                 ; mount may fail due to 
the phone is not ready to do F/T

wait for phone to ask Allow/Deny and press Allow

# ls /mnt may see nothing but Input/output error because mounting 
process was done before phone allows F/T

# umount /mnt

#  jmtpfs -o allow_other /mnt              ; this time mount should be 
successful

if phone asks Allow/Deny again due to some kind timing issue, try to do 
umount and jmtpfs mount one more time.
