Tried plugging my Samsung Note 4 into the USB port and apart from charging it seems to do nothing!!!! Looks like it doesn't support Android file system.

No the end of the world but Apple bias is always a bit annoying

Same issue here. I looked it up and it seams that Android as a whole lost that capability a while ago with a version upgrade.

I bluetooth mine, and also use a usb pen with my music on. I use a car charger to charge my phone as the usb socket now serves no other purpose and I use the usb socket for the music pen.

You can use it as long as it's in fat32 and USB OTG enabled. You'll need to root the phone though.... I'll Confirm as soon as I get mine, but that's how I've got mine to work in every car I've driven
