Key Features in iOS 15

1. FaceTime Upgrades

FaceTime received significant audio and video enhancements to make calls feel more natural:

• Spatial Audio: Spreads out voice audio so it sounds like it originates from the direction the speaker is positioned on the screen.
• Voice Isolation: Uses machine learning to block out background ambient noise.
• SharePlay: Enables users to watch movies, listen to music, or share screens together during calls.
• Cross-Platform Links: Generates web links allowing Windows and Android users to join calls via a web browser.

2. Focus Mode and Notifications

To help users minimize digital distractions, iOS 15 introduced:

• Focus Modes: Pre-set or custom configurations (like Work, Personal, or Sleep) that filter notifications based on what the user is currently doing.
• Notification Summary: Collects non-urgent alerts into a scheduled morning or evening bundle.
• Redesigned Banners: Features larger app icons and contact photos to make alerts easier to identify at a glance.

3. Live Text and Visual Look Up

• Live Text: Automatically recognizes text within images, screenshots, and the Camera viewfinder, allowing users to copy, paste, translate, or call phone numbers directly from an image.
• Visual Look Up: Identifies plants, pets, landmarks, and artwork directly within the Photos app.

4. Redesigned Safari

The Safari browser introduced a modular tab bar positioned at the bottom of the screen for easier one-handed navigation, alongside Tab Groups, which allow users to organize and sync sets of tabs across their Apple devices.

5. Privacy Improvements

iOS 15 expanded Apple's commitment to user data protection through:

• Mail Privacy Protection: Prevents email senders from tracking IP addresses and seeing whether an email was opened.
• App Privacy Report: A dedicated settings menu showing how often apps access location, photos, camera, microphone, and contacts over a seven-day period.

Device Compatibility

iOS 15 maintains broad hardware support, running on all devices capable of running iOS 14. This includes the iPhone 6s and newer, iPhone SE (1st generation and later), and iPod touch (7th generation).
