KitKat 4.4.2 on Note 3. I can no longer transfer files between my phone and my computer. Don't even know whether it's a Win7 problem or an Android issue, but suspect Android since the computer does continue to recognize thumb drives and camera. I'm using the original USB cable. When I plug it in, the phone charges, but simply is not recognized as a device by Win7. Android settings > Storage does not offer any way to check or alter MTP setting. I have a whole lotta music stranded on my computer. Grrrrrrr.
