According to reports, the fresh update is the most extensive operating system upgrade since its autumn release, featuring both the adaptation of system functions for the flexible display, a significant expansion of Siri AI voice assistant capabilities, and a redesign of the Health app. ### Reachability, Reimagined for the Foldable Screen To make one-handed use of the external 5.4-inch OLED display on the iPhone Duo more convenient, developers changed the logic of the Reachability feature. On regular iPhone models, this feature shifts the screen content downward. On the flexible device, the mechanics work differently: swiping from the left or right edge of the display moves the interface closer to your thumb. This allows the user to reach buttons and other controls in the opposite corner of the screen without having to shift the device in their hand. The feature can be enabled in the Settings — Accessibility — Touch menu. ### On-Screen Input and Keyboard on the External Display Simultaneously, Apple modified the on-screen keyboard on the iPhone Duo's external display, adapting it to the compact format of the foldable screen. The changes ensure that typing and interacting with the interface on the smaller panel are just as comfortable as on the main part of the device. ### Siri AI Learns to Execute Command Chains Inside Apps In addition to improvements for the iPhone Duo, iOS 27.3 brings a massive expansion of autonomous actions for the Siri AI voice assistant. The tool has gained the ability to execute complex chains of commands within applications: in the Mail client, the assistant can unsubscribe from mailing lists and recall emails; in Safari, it can clear browsing history and close duplicate tabs; and in Files, it can organize content. Thanks to the App Intents framework, third-party developers can now integrate their own scripts into the Siri AI system, paving the way for expanding the ecosystem of autonomous scenarios. ### Redesigned Health App and New Analytics Apple also introduced a redesigned Health app featuring two new analytical sections. The Insights section displays up-to-date information on heart rate and sleep phases with personal tips from Apple Intelligence, while Longevity calculates a biological parameter called "Health Age" based on cardiovascular data. ### Additional Beta Changes Additionally, the iOS 27.3 beta includes a vertical tabs mode in Safari and new styling options for StandBy screens. The combination of these innovations confirms that Apple is continuing to consistently adapt its platform for the foldable device form factor and deepen AI integration into everyday use scenarios. ## Fact-Check & Sources - [Удобное управление одной рукой: iPhone Duo получил новые функции в iOS 27.3](https://www.rbc.ua/ukr/news/zruchne-keruvannya-odnieyu-rukoyu-iphone-1793952419.html) - Primary source; contains all base facts: Reachability for foldable screen, keyboard, Siri AI, Health, Safari, and StandBy.

The assistant has learned to execute command chains inside apps: unsubscribing and recalling emails in Mail, clearing history and closing duplicate tabs in Safari, and organizing content in Files. Through App Intents, third-party developers can connect their own scripts. ### What's new in the Health app? Two new analytical sections have appeared: Insights (heart rate and sleep phases with Apple Intelligence tips) and Longevity (calculating the biological parameter Health Age based on cardiovascular data).
