Some of iOS 11's changes: the lock screen and Notification Center are combined, allowing all notifications to be displayed directly on the lock screen. The various pages of the Control Center are unified, gaining custom settings and the ability to 3D Touch icons for more options. The App Store receives a big visual change to focus on editorial content and daily highlights. A "Files" file manager app allows direct access to files stored locally and in cloud services. Siri can now translate between languages and use a privacy-minded "on-device learning" technique to better understand a user's interests and offer suggestions. The camera has new settings for better portrait-mode photos and will use new encoding technologies to reduce file sizes on newer devices. In a future release, Messages will be used with iCloud to better synchronize messages across iOS and macOS devices. A previous point release also added support for person-to-person Apple Pay payments. The operating system also introduces the ability to record the screen, limited forms of drag-and-drop functionality, and support for augmented reality. Certain new features will appear only on iPad, including an always-accessible application dock, cross-app drag-and-drop, and a new user interface to show multiple apps at once.
