Apple Is Working on Improving the Safari Interface

Updated Safari Capabilities for iPhone Duo
Apple is actively working on refining the Safari interface for the iPhone Duo. The company’s goal is to provide more space for web pages on the device's outer screen, which is currently restricted by the layout of the control buttons. With the current design, the browser displays web pages only in the area beside the buttons, while the remaining space is filled only with the background colour.
Technical Challenges and the Role of Web Developers
According to Jen Simmons of Apple’s WebKit team, the issue lies in the fact that the existing viewport-fit="cover" parameter allows web pages to fully utilize the edges of the screen, but many sites are not prepared for this. As a result, content can end up underneath the browser’s navigation controls, making it inaccessible to the user. The company is currently exploring alternative ways for developers to have more control without obscuring information. One option being considered is extending the header background across the entire screen while keeping navigation buttons within a safe zone.
New Features and Future Prospects
In addition to optimizing the Safari layout, the Safari 27.1 update has offered extra convenience to iPhone Duo users. When the device is folded halfway like a book, PDF documents automatically open in a two-page view. When the device is fully opened or closed, the interface automatically reverts to the standard single-page view.
Furthermore, experimental features are now available to developers that allow for the detection of the device's folding state and the arrangement of content based on the hinge area. These capabilities are currently hidden within Safari’s experimental settings. Although a definitive solution for the Safari interface is still in the research phase, these changes signal Apple’s desire to maximize the potential of the iPhone Duo’s unique screen format and provide users with a more convenient working environment.
