How to Install iOS 27 Developer Beta 3? Here's What's New and the Full List of Supported iPhones

Apple has rolled out iOS 27 Developer Beta 3, giving developers and early testers another preview of the next major iPhone software update. The latest beta introduces new AI-powered accessibility features, expands Siri customization options, and brings refinements across several built-in apps, including Photos, Reminders, Maps, Home, and Control Center.

While primarily aimed at developers, the update also offers a glimpse of the features expected to arrive with the stable iOS 27 release later this year.

iOS 27 Beta 3 Brings Live Recognition and Siri Upgrades

The biggest addition in iOS 27 Developer Beta 3 is Live Recognition, an AI-powered accessibility feature that uses the iPhone's camera to help users better understand their surroundings. Apple says the tool can identify objects, describe nearby scenes, and answer questions about whatever the camera is pointed at. Since the feature runs on-device, it is expected to deliver faster responses while keeping user data private.

Apple has also expanded Siri's voice customization options. Users can now adjust Siri's speaking style, including its speed and expressiveness, making the voice assistant sound more natural and improving accessibility for a wider range of users.

The update also includes several smaller enhancements. The Reminders app gets a refreshed Liquid Glass-inspired icon, the Photos app can now display star ratings for photos and videos, and Control Center is capable of showing cellular signal strength even while the iPhone is connected to Wi-Fi.

Supported iPhones for iOS 27 Developer Beta 3

Apple has made iOS 27 Developer Beta 3 available for the following iPhone models:

• iPhone 17 series
• iPhone 16 series
• iPhone 15 series
• iPhone 14 series
• iPhone 13 series
• iPhone 12 series
• iPhone 11 series
• iPhone SE (2nd generation and newer)

However, Apple notes that not every iOS 27 feature will be available on every supported device. Apple Intelligence and other AI-powered features require newer chipsets, meaning older compatible iPhones may receive the update but miss out on certain advanced capabilities.

How to Install iOS 27 Developer Beta 3

If you're enrolled in Apple's Developer Program, installing iOS 27 Developer Beta 3 is a straightforward process.

1. Open the Settings app on your iPhone.
2. Tap General.
3. Select Software Update.
4. Tap Beta Updates.
5. Choose iOS 27 Developer Beta.
6. Return to the Software Update page and download the available update.
7. Follow the on-screen instructions to complete the installation.

Before installing, it's highly recommended to create a complete backup of your iPhone. Developer beta builds may contain bugs, app compatibility issues, battery drain, overheating, and unfinished features, making them better suited for a secondary device than a primary smartphone.

With Live Recognition, enhanced Siri controls, and several quality-of-life improvements across core apps, iOS 27 Developer Beta 3 offers one of the most feature-rich previews of Apple's upcoming software. While developers can begin testing their apps with the latest build, most users will likely have a smoother experience by waiting for the public beta or the stable iOS 27 release later this year.
