How can I mount my google nexus4 on linuxmint(nadia) computer via usb?
This question gets asked a lot about Linux in general.  MTP from the default repos will work in Mint, no problem.  I've written a tutorial on how to get MTP devices recognized under Ubuntu, but it's the same for Mint:

Install MTP:


sudo apt-get install mtpfs


Create a directory to mount your device:


sudo mkdir /media/MTPdevice (call the directory whatever you like)
sudo chmod 775 /media/MTPdevice
sudo mtpfs -o allow_other /media/MTPdevice


Plug in you phone and use MTP tools to determine the VID and PID (or, if those don't appear in the output, idVendor and idProduct):


mtp-detect


Add a rule to udev to handle your phone:


gksu gedit /etc/udev/rules.d/51-android.rules


Text to add:  (substitue VID and PID for "" and "")

SUBSYSTEM=="usb", ATTR{idVendor}=="&lt;vendorId&gt;", ATTR{idProduct}=="&lt;productId&gt;", MODE="0666"


Restart udev:


sudo service udev restart


You may also need to reboot, depending.

This works on my Linux Mint 15 + MATE box.

NOTE:  If you have your device locked (eg, which a swipe code or PIN), you’ll need to unlock it before your SD card(s) can be recognized by MTP and have it mount them for you to access locally.
