Answer to: Samsung Galaxy A5 2016 usb connection won't show upThere is a video that shows how to do it: https://www.youtube.com/watch?v=rQQTVr29... I did all that and it still didn't work so I dug out the original white charging cable that came with the phone and connected that. When it still didn't recognize the phone I rebooted while the cable was connected and voila! it worked. I was still had it set on MTP connection though not PTP.
