Is there a way to set up a room to inhibit all the capabilities of an smartphone? Microphone, antenna, GPS, camera, signal, etc... Of course without endangering the present people.

Faraday cage design shielded rooms exist in many facilities for sensitive meetings, but unless you also remove all potential recording devices from the participants they would still be able to just record and transmit later.

I suspect a lot of these rules/recommendations are more around the fact that a phone can easily serve as both an audio and video recording device than that a hacker can gain control of someone's personal iPhone.

We've sort of normalized everyone having a camera on them most of the time and whipping it out to record a whiteboard after a meeting. But I can remember the days when bringing a camera into company facilities required a fair bit of security rigamarole. (I needed to shoot some pictures of old gear for a presentation.)

That's a faraday cage or a Sensitive Compartmented Information Facility (SCIF)

Or if your the Mafia "Johnny Pliars" collects your phone before you go into the backroom :-)

The faraday cage doesn't prevent exfiltration by just walking out the door with the recording on your phone.

That's what "Mr Pliers" is for or more likely the Red Cap with a Holstered Webley

Why would somebody be that motivated to carry a phone somewhere, even if that phone is completely disabled and useless? Maybe there's a market for phone-shaped pieces of plastic for people who need something to caress at all times.

Not without the cooperation of the phone itself, I don't think.
