If you’re looking to keep your PlayStation 4 game hidden from view, there are a few things you can do. One is to use a game controller’s mute function. Another is to create a custom profile for your PlayStation 4 and disable any PS4 features that might be used to track or identify your game play. Finally, you can hide the system’s icons and messages on startup by using the “PS4™ System Settings” option in the “Settings” menu of your PlayStation 4 console.
