iOS 27 Beta 4: New Features and Changes (2026)

iOS 27 Beta 4: A Sneak Peek at Apple's Upcoming Operating System

As we approach the September launch of iOS 27, Apple continues to fine-tune its latest operating system with the release of the fourth developer beta. While there are fewer changes compared to previous betas, each update brings us closer to understanding the direction Apple is taking with this major release. So, what's new in iOS 27 Beta 4, and what does it reveal about Apple's vision for the future of its mobile operating system?

One of the most notable additions is the new Automatic Downloads toggle in the TV app's Settings section. This feature automatically downloads the next two episodes of shows you start watching in the Continue Watching section, ensuring you never miss a beat. However, what makes this feature particularly fascinating is its potential impact on user experience. By automatically downloading episodes, Apple is taking a proactive approach to content consumption, potentially reducing the need for manual downloads and improving overall convenience. This is especially interesting in the context of the generative AI era, where personalized and context-aware experiences are becoming increasingly important.

In the Photos app, a new 'Zoom Photos to Fill' toggle slightly zooms photos that nearly match the screen's aspect ratio, and it is turned on by default. While this may seem like a minor change, it showcases Apple's attention to detail and its commitment to enhancing the user experience. The feature is particularly useful for those who want to showcase their photos in the best possible way, and it highlights Apple's understanding of the importance of visual presentation in the mobile space.

On the other hand, the removal of the wallpaper feature in the Notification Center is a bit of a disappointment. This feature allowed users to see a cutout of the subject of their wallpaper on the Home Screen, providing a unique and personalized experience. However, Apple's decision to remove it may suggest a shift in focus towards more functional features, such as the new ProRes log format in the Camera section of the Settings app. This format, which retains more information in the file for additional flexibility when editing color and making adjustments, is a welcome addition for video enthusiasts and professionals.

The Siri Voice selection interface has also undergone a change, with more voice options available on devices with custom Siri selections. This is particularly interesting in the context of the dual-battery iPhone references found in the code. The strings 'The batteries in this iPhone are performing as expected' may hint at the foldable iPhone Ultra, which is expected to have a dual-battery design. This suggests that Apple is preparing for a significant shift in the iPhone's design and functionality, potentially paving the way for a new era of mobile computing.

In the Siri Settings section, a new option allows users to adjust the length of previews in the Siri app, providing more control over the information presented. This is a welcome addition, as it allows users to customize their experience and focus on the information that matters most. Additionally, the new 'Always Show Request' toggle in the Accessibility section shows a transcription of what you say to Siri on the screen, providing a more transparent and user-friendly experience.

Overall, iOS 27 Beta 4 reveals a lot about Apple's vision for the future of its mobile operating system. From the new features to the subtle changes, each update brings us closer to understanding the direction Apple is taking with iOS 27. As we await the September launch, it's clear that Apple is committed to refining its flagship operating system and delivering a seamless and intuitive user experience. So, what do you think? What are your thoughts on the new features and changes in iOS 27 Beta 4? Personally, I think the focus on context-aware experiences and personalized features is a refreshing change, and I'm excited to see how Apple continues to innovate in the mobile space.
