mtp mount Galaxy S3 with jmtpfs or simple-mtpfs 
kio-mtp and mtp-detect stopped working :-(

But jmtpfs seams to work - i decided to mount on usb plug in with an udev rule
#> apt-get install jmtpfs
#> mkdir -p /media/mtp
ACTION=="add", ENV{ID_MTP_DEVICE}=="1", RUN="/usr/bin/jmtpfs -o allow_other /media/mtp"
ACTION=="remove", ENV{ID_MTP_DEVICE}=="1", RUN="/bin/fusermount -u /media/mtp""

A little bit faster is simple-mtpfs, but you have to compile

apt-get install libusb-dev libmtp-dev

git clone
cd imple-mtpfs
mkdir build && cd build
../configure --prefix=/usr
sudo make install

ACTION=="add",ENV{ID_MTP_DEVICE}=="1",RUN="/usr/bin/simple-mtpfs -o allow_other /media/mtp"
ACTION=="remove", ENV{ID_MTP_DEVICE}=="1", RUN="/bin/fusermount -u /media/mtp""

hostap with a wifi usb stick on demand 
After plug in of a wifi usb stick linux act's as a hostap.

apt-get install isc-dhcp-server hostapd

changes in /etc/hostapd/hostapd.conf
wpa_pairwise=TKIP CCMP

iface wlan0 inet static
hostapd /etc/hostapd/hostapd.conf
up iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
up /etc/init.d/isc-dhcp-server restart
down iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
down killall hostapd

first check vendor and product id with lsusb:

ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="148f", ATTRS{idProduct}=="3070", \
RUN+="/sbin/ifup wlan0"
ACTION=="remove", SUBSYSTEM=="net", KERNEL=="wlan0", RUN+="/sbin/ifdown wlan0"

On booting this does not work for me so i started the hostap by

lsusb | grep -q "148f:3070" && /sbin/ifup wlan0
