Answer 1

Without getting into why the imperfections happen in the first place, professional productions have a post-production step where imperfections are handled. Your phone videos often do not.

Answer 2

Professionals use synchronized cameras, or simply replace the screen displays in post-production with CGI. Professional cameras have lots of adjustments, like longer exposure times, that can give cinematographers more options to capture displays.
