This a a description on how I could connect the mobile phone Samsung Galaxy S7 to a Linux machine. The goal was to transfer files for backup purposes as well as the capability to keep the date/time of photos and videos while transfering files between the PC and the phone.
For this procedure no cable connection is necessary: A WLAN connection is sufficient, as long as the Linux-PC and the phone (via the WLAN access point) are connected to the same switch)

- Install "SSH Helper" on the smart phone (available on Google Market)
- Start "SSH Helper" and click on the 'tool' on top>br> - Read the IP-number (e.g. 192.168.0.103)
- Read the port number (e.g. 2222)
- From the Linux-machine start a SSH connection to the phone:
    user=your_username_on_Linux
    pw=default_password_on_the_phone=admin    

ssh user@192.168.0.103
.....

- External SD-Card: df   -->  /storage/3762-3731    59.4G    10.7G    48.7G 

- cd /storage/3762-3731


scp -p ...............




Files of type:  20140510_192957.mp4   or  20160618_005049_001.jpg

for file in `ls -1 *.jpg *.mp4` ; do echo $file; dat=`echo $file | cut -c 1-8`; echo $dat;time=`echo $file | cut -c 10-13`; echo $time; dattime=`echo $dat$time`; echo $dattime; touch -t $dattime $file ; done

Files of type:  04062011048.jpg  (Modify only Files of 2011 in this format):
for file in `ls -1 ????2011???.jpg` ; do echo $file; yr=`echo $file | cut -c 5-8`; month=`echo $file | cut -c 3-4`; day=`echo $file | cut -c 1-2`; time="1200"; dattime=`echo $yr$month$day$time`; dattime=`echo ${dattime}`; echo ${dattime}; touch -t $dattime $file; done

Vom Galaxy aus:

scp -p *.jpg user@IPnumber_Linux_PC:  

--> preserver date/time of the copied files.


Funktioniert noch NICHT!!!!


Android: touch --h    for help


busybox touch -c -t 201404080024 20140408_002436.jpg
