How to turn on USB connection to PC I bought a KingSing K5 Android phone, and there doesn't seem to be an option for turning on USB connection to PC (to transfer files). I have the Google USB driver installed on the PC, but when I connect nothing happens. Is there a specific way to turn on USB connection in Android 4.2.2?
you just have to enable usb debugging mode.
go to settings scroll down to developer options. Under that the first option is  usb debugging. enable that
