As of now, we have a smartphone (Android - Marshmallow), and I am trying to figure out security options for the device. These things are not like an OEM computer were one can uninstall unwanted junkware programs and move on - and the part that concerns me the most is app permissions. Why the heck do apps need permissions (access to contacts, phone calls, etc,) anyway? I don't know of any Windows computer that asks such questions - unless Windows 10 fits that bill. Do Android phones come with built-in antivirus programs? If not, any recommendations, and does anyone here use an app to monitor for permissions - like Permission Dog?
