Apple may still be holding back a few iOS 27 features that did not appear at WWDC 2026. Bloomberg says internal builds still include Siri chatbot extensions, a redesigned Camera app, and a modular Apple Watch Ultra face.

That mix points to two clear priorities for Apple: deeper AI support in Siri and a more premium camera experience for the next iPhone cycle. The leak also suggests Apple is using software to separate some devices more clearly than before.

Apple Watch Ultra Could Get an iOS 27 Modular Watch Face

One of the reported features is a modular watch face, and the current reporting suggests it may not be a broad rollout across every Apple Watch. Instead, the Apple Watch Ultra looks like the most likely candidate for the feature.

If that happens, it would fit a familiar Apple pattern. The company often uses software features to make its highest-end devices feel more distinct, and an Ultra-only watch face would do exactly that. For buyers comparing premium smartwatches, customization and screen density are often part of the decision, so a feature like this could matter more than it sounds at first.

Bloomberg’s reporting also leaves room for change. Features that remain in testing can still be adjusted before release, so the final version of iOS 27 may look different from what is currently being discussed.

Siri Chatbot Extensions Point to Apple’s Next AI Push

The other major feature in testing is tied to Siri, with Bloomberg saying Apple is working on chatbot extensions that would expand AI model support inside the assistant. That would mark another step in Apple’s wider push into on-device and cloud-assisted AI, even if the exact implementation is still unclear.

For now, the most important detail is the direction. Apple appears to be preparing Siri for a more flexible chatbot layer, which would bring it closer to what users already expect from AI tools on Android and elsewhere. The leak does not spell out which models or services may be supported, so those details remain unknown.

That missing information matters. Without more specifics, it is hard to say how deep the integration will go or which devices will get the full experience. Still, the presence of these features in internal builds suggests Apple is not done expanding Siri’s role in iOS 27.

The Redesigned Camera App Could Target the iPhone 18 Pro Cycle

The third feature is a redesigned Camera app, and the timing appears to line up with the iPhone 18 Pro cycle. That makes it one of the clearest signs that Apple is thinking about iOS 27 not just as a software update, but as part of a broader flagship hardware strategy.

A new camera interface would likely be aimed at improving the user experience on Apple’s premium phones, where camera quality and ease of use are major selling points. Bloomberg’s report does not give specific design details, so it is not possible to say how large the redesign will be.

Even so, the focus on the Camera app is easy to read. Apple’s premium iPhone lineup competes heavily on imaging, and any interface changes tied to the next Pro generation would fit that market pressure. If the redesign ships, it could become one of the more visible parts of iOS 27.

For now, the leak points to a familiar Apple pattern: hold back a few notable features, test them quietly, and release them when the software and hardware story is ready. The result may be a more complete iOS 27 later this year, but the reporting also shows that several of the update’s most interesting changes are still not final.
