Apple is rolling out the iOS 27 Public Beta update for iPhone. First previewed at WWDC 2026 in May, the company introduced a developer beta of the latest iPhone operating system last month. However, it was only available to registered Apple developers and beta testers. It brings improvements to Liquid Glass, a smarter Siri, new features in Photos and Mail apps, and more. Alongside, Apple has also released similar public beta updates of iPadOS 27, watchOS 27, macOS Golden Gate, and more.

So, if you have not had a chance to try out Apple's latest update, you can do so following the rollout of the iOS 27 Public Beta. Here's what you need to know.

iOS 27 Public Beta: What's New

iOS 27 Public Beta carries all the changes that have been available with the Developer Beta updates post WWDC 2026. Among the headlining additions is the new Siri, which has received a major overhaul. It is now available as a dedicated app on iPhone and via Spotlight on Mac. The assistant has been integrated into the Dynamic Island and appears as an animated visual indicator when activated.

Apple claims it is a modern AI chatbot, offering broader world knowledge, improved conversational memory, and deeper integration with third-party and system apps on the phone. Siri can respond to follow-up questions naturally, without having the user repeat context, while also being capable of performing multistep tasks. There are also new Siri options, such as the Write with Siri shortcut in Notes, Mail, Messages, and other apps.

Apple's Liquid Glass design language, introduced with iOS 26, has also received refinements following user feedback. Among them is a new slider that allows users to fine-tune transparency levels.

In the Photos app, there are new photo editing tools. Users can clean up backgrounds, remove unwanted objects, reframe images, extend scenes beyond their original boundaries, and even generate new perspectives within photographs. iOS 27 Public Beta also brings new child safety tools, including the ability to limit access to specific apps during certain times of the day, restrict communications to approved contacts, and manage website permissions more effectively.
