Snapchat has announced a new feature allowing iPhone users with iOS 18 or later to replace their default lock screen camera shortcut with the Snapchat camera. This integration aims to simplify the process of capturing moments, as over 55,000 Snaps are created every second. Users can customize their lock screen by selecting the Snapchat camera through the customization options. Additionally, Snapchat has launched the 'Footsteps' feature for tracking world exploration and is introducing new Halloween-themed AI lenses and stickers. This update follows Snapchat's previous enhancements with iOS 16 and iPhone 15.
