Display messages on the current screen

Translation via Google Translate:

Hello. After updating the system, when a message arrives, its content is displayed on the current screen. Is it possible to switch it off somehow?

Witam. Po aktualizacji systemu, gdy przychodzi wiadomość na ekranie bieżącym wyświetla się jej treść. Czy można to jakoś wyłączyc?

@Ruda96 please post your replies in English. since it's an international forum, more people will be able to understand you and possibly come up with a solution.

do you mean the notifications that pop up on the lockscreen, or near the top edge of the screen while you're using your phone?
