but how to it with Samsung S7572?

I have a Samsung Galaxy Indulge (R910, Android 2.2.1) phone that automagically mounts on Wheezy Xfce when plugged in. Then metroPCS upgraded their cellular network, dropped support for that model, and I needed a new phone.


So, I bought a Motorola Moto G (XT1045, Android 4.4.4) from AT&T. When I plugged it in to Wheezy Xfce, nothing happened. After much STFW, RTFM, etc., I learned that I needed to use Media Transfer Protocol:

    https://en.wikipedia.org/wiki/Media_Transfer_Protocol


This is available via FUSE on Wheezy.  I installed two Apt packages:

    jmtpfs
    mtp-tools

created a mount directory:

    $HOME/xt1045

added myself to the FUSE group:

    usermod -a -G fuse dpchrist

and figured out how to mount and umount the phone. (I can't remember if I needed to do anything on the phone, and I don't see anything in the settings now that looks relevant.) I put the relevant commands (with some simple checks) into a pair of shell scripts. See the sample console session that follows.
