i want the drivers of my phone to be installed in Ubuntu 12.04 Lts please help me on this
You need not to install any extra driver for your Smartphone to use it as a mass storage device. I am also having Samsung galaxy duos and there is no problem like this. What you have to do is, simply connect your phone with laptop/desktop using data cable. It will automatically detect your phone. Ubuntu12.04LTS is preloaded with the necessary drivers.
