I combat this habit by placing a window over the top of whatever app I’m using for the video call so my eyes stay on the camera. That strategy is foiled the moment screen sharing becomes required, but more often than not I know exactly what they’re talking about. As I’ve never been on the receiving end of this strategy who knows if it makes me look better or like a weirdo…
I’m w/ you on this assuming the question is: “Who needs it on their phone.” It’s the “on their phone” part that matters. It’s like…Who needs a can opener? Most people. Who needs a can opener on their phone? Not many people. The bigger problem being the can opener wouldn’t be as good as the standard tool & the price of the phone would increase. If I wanted/needed a thermal camera I would prefer to buy a dedicated device w/ high performance sensors.
