I just got a new phone and I want to start putting stuff on it like my music, but Ubuntu won't display the contents of the device when I connect via USB. I've tried looking into this problem, and I followed this guide, but I didn't have any luck in getting this to work. I also looked here but I don't really understand what mtp or gvfs or any of that is so I have no idea if my device even qualifies for these guides. Anyone know what could be going wrong? Any help would be appreciated.
