According to this article, Samsung doesn’t block that, it’s just badly implemented:

I mean that makes sense. Samsung doesn’t bill it’s front screen as a full phone, it’s supposed to be just a window for quick info at a glance. It’s probably more just Google hasn’t made its app compatible with the flip’s cover screen. In any case at this point the screen on the flip 5 is actually a decent size so it should be able to run any app like the razor.
Razor phone runs the app. From the article, it fails because Google makes the app run as using play services and Samsung has a whitelist for apps to go the small screen, it can add the shortcut, but since it launches an intent behind play services, that is blocked.
