What role does the 'Settings' app play in managing device features?

The 'Settings' app is a crucial part of managing a device's features, as it serves as the central hub where users can customize and control various aspects of their device. Within the app, users can adjust settings related to sound, display, privacy, network connections, and more, effectively tailoring their device to their personal preferences and needs. This capability for customization empowers users to optimize their experience, enhance security, and manage functionality according to their specific requirements. Having direct access to these configurations also allows users to troubleshoot issues and ensure their device operates in an optimal manner.

The other options describe functionalities that are not within the primary purpose of the 'Settings' app. While playing games and accessing social media are integral to the user experience on a device, they occur through dedicated apps rather than the Settings app. Notifications are managed within the Settings app, but it is not limited to merely displaying them; rather, it provides comprehensive tools to manage how and when notifications appear. Thus, the primary role of the 'Settings' app is to offer robust controls for customizing and managing the device's features.
