No. You don't. Because that isn't possible to do. The fact that this guy even said that means he is clueless about mobile. He needs to be replaced.
Ah our resident doofus. If he said he had a PC to replace your phone, obviously he'd be clueless. A phone to replace your PC? Why not, for most people their phone now has way more power than the PC had ten years ago, it just has bigger input/output devices. Microsoft could make a x86 phone with a HDMI/DisplayPort/USB dock (or just an USB-C cable hookup) and it'd make a perfectly satisfactory PC for most people. His problem will be that nobody wants the phone side of it, they want their iApps or Google Play-apps.
