Issues
Connecting mobile device via USB does not allow file transfer
When you connect your android mobile device, like the Samsung Galaxy S5, Google Nexus 6, or LG G4, the device does not appear in your computer but the phone charges normally. The reason for this is that not all micro-usb cables support file transfer. You will need to buy a new micro-usb cable.
