I an trying to put all my music onto my s4 as when I try to do it with kies it says that my phone doesn't have enough memory even though it has 9gb left and I am only transferring 1gb. I understand that I need to download android file transfer and have changed my phone to camera mode when I connect it. But the android file transfer says that I need to connect the device using a USB. Why wont it recognise my device?
