When I connect my N4 to the PC, it shows up as "internal storage". When I click internal storage, it shows two folders, "DCIM" and "Pictures". It used to show a higher root folder like "sdcard", I think. I'm not sure if this started happening after the 4.3 update or whether something else I did caused it. How do I get it back to show sdcard. I've tried different USB cables and usb ports. Also, under MPT usb mode nothing shows up when connected to computer. Its only under MPT mode that I even get the pictures and dcim folders.
