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.

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.

Because they change the setting on their camera to compensate.

Screens are just strobe lights that’s are so fast you can’t see them turn off. So the flashing screen on a camera is because you hit the timing just right. A refresh rate for most screens is 60 per second, and cameras are 30 frames per second.

TV and computer screens flicker in videos because they *roll* at the same rate as the screen you are watching on. If its professionally done then it us a simulated screen.

The light flickers at a certain speed, cameras with manual shutters can change so that the flicker doesn’t show. Your phone doesn’t have this.
