Sony Ericsson LT 15i connection computer does not recognize.
This is a mobile phone driver problem. I suggest you download Kingsoft, install it in your computer, and then open the software. Click the icon in the lower left corner to install the driver, and you will see that there is something wrong with Sony Ericsson's driver (you can only see it if you connect your mobile phone to a computer). Finally, download and install the driver and it will be solved!
