The leaker, known as pdfu, posted a video showing the Dynamic Island toggling between three simultaneous Live Activities, matching what Bloomberg‘s Mark Gurman described in his report earlier today. “The new Dynamic Island with 3 items is already supported in iOS 27,” pdfu wrote.
Great reporting from @markgurman. The new Dynamic Island with 3 items is already supported in iOS 27. Here’s what it looks like.
The code requires a sensor region less than 100 layout points wide, or below 16.57 mm for this new mode. iPhone 17 Pro was 20.76 mm. https://t.co/jZshu4rFXx pic.twitter.com/mL46rcEirh

According to pdfu, the underlying code requires a sensor region less than 100 layout points wide to enable the new mode, or below 16.57mm. Layout points are Apple’s device-independent unit for describing on-screen dimensions, and they scale differently depending on a display’s resolution. By comparison, pdfu notes that the sensor region on the current iPhone 17 Pro measures 20.76mm, meaning Apple would need to shrink the hardware by roughly 20% to unlock the new software behavior.
The iPhone 18 Pro and iPhone 18 Pro Max have been rumored to feature a smaller Dynamic Island for months, but reports about support for a third, additional Dynamic Island Live Activity is new. Since the iPhone 14 Pro launched in 2022, the Dynamic Island has only supported two Live Activities, so adding a third seems like a worthwhile way to demonstrate the utility of shrinking the region.
