What are the consequences after stopping system.ui?

Question

Android

What happens if System UI stops responding on Android. This is a system component and cannot be stopped on its own. Some errors in the robot (or code) happen.
By the way, on my old Samsung, the system launcher did not respond, it was necessary to format the internal memory.

Answer 1

The phone will stop responding to user actions.
Usually, in this case, the application just crashes. If the error is in the application, of course.
