What does the gesture of swiping down from the top right corner of an iPhone screen do on iPhones with Face ID?

Swiping down from the top right corner of an iPhone screen on devices equipped with Face ID is designed to access the Control Center. The Control Center provides quick access to various settings and functionality, such as Wi-Fi, Bluetooth, Airplane Mode, brightness control, and music playback. This gesture was implemented to provide users with an efficient way to manage these settings without having to navigate through multiple menus.

On devices that utilize Face ID, the interface is tailored to accommodate the absence of a home button; thus, gestures play a crucial role in navigation. The specific action of swiping down from that corner has been standardized to ensure consistency across all iPhones with Face ID, making it easy for users to remember how to access essential tools and settings quickly.
