iOS 27 Developer Beta 1 is installed and running on a primary iPhone 17 Pro. The update ships with AI-powered Photos tools including Cleanup, Extend, and Reframe, live captions for videos, Liquid Glass slider customization, a new Wallet pass creator, and camera UI changes. Performance improvements are present but modest in early testing.
The headline problem: the redesigned Siri Apple centered its WWDC presentation around is not functional in this build. Users must join a waitlist, and access has not been granted. That gap makes iOS 27 Beta 1 feel incomplete at its core, regardless of what else works.
The Photos AI section, running from the 2:38 to 7:22 timestamp, is the most substantive part of the video. The Extend and Reframe demos show before-and-after results that reveal actual capability limits, not just marketing clips. If you want to know whether these tools hold up on real photos, that segment is worth watching in full.
