I\'ve just installed VS2015 Community with Xamarin to develop some mobile apps. The problem is, I can\'t achieve debugging Android apps on any device. Android Device Monitor
I had the same problem, using a Samsung Galaxy A5
Plugging the phone in while Visual Studio was opened resulted in a pop up asking for permission. After authorising, everything worked perfectly. I didn't have to go into the developer settings on the smartphone and revoke the USB debugging authorisation.
