Key Features of iOS 15

• FaceTime Improvements: Apple expanded FaceTime by introducing spatial audio, voice isolation to block background noise, and Portrait mode for video calls. Additionally, FaceTime links allowed non-Apple users on Android and Windows to join calls via web browsers, while SharePlay enabled synchronized media sharing.
• Focus Mode: Building upon "Do Not Disturb," Focus mode allows users to filter notifications and home screen pages based on their current context, such as Work, Personal, Sleep, or Fitness.
• Live Text: Leveraging on-device machine learning, Live Text recognizes text within photos, screenshots, and the Camera app. Users can copy, paste, look up, and translate text directly from images.
• Redesigned Notifications: Notifications received a visual overhaul with larger app icons and contact photos. A new "Notification Summary" feature bundles non-urgent alerts into scheduled daily digests.
• Safari Redesign: Safari was updated with a floating, bottom-placed address bar for easier one-handed navigation, along with customizable start pages and Tab Groups for organized browsing.
• Enhanced Privacy Protections: iOS 15 introduced Mail Privacy Protection, which hides IP addresses and prevents senders from knowing if an email has been opened. The system also added on-device Siri processing and the App Privacy Report to show how apps access sensors and data.
• Apple Maps and Wallet: Maps gained interactive 3D globes, enhanced driving details, and augmented reality walking directions. The Wallet app expanded to support home keys, hotel room keys, and digital driver's licenses.

Device Compatibility

iOS 15 maintained support for all devices capable of running iOS 14. This included older devices ranging from the iPhone 6s, 6s Plus, and the first-generation iPhone SE, all the way up to the iPhone 13 lineup released alongside the operating system.
