It doesn't play super nice with foldable phones. The UI doesn't adapt correctly without restarting the app and you end up with a very dense interface of overlapping buttons if you try going from open to closed. The address bar becomes completely blocked by all the extra buttons from the tablet layout, so the app is unusable.
Aside from the fact it's a greentext and probably fake, I could understand recognizing a face from a movie or something and still not knowing who they are.
I guess it needs a cable though, and Phone Link is wireless?
