Apple began rolling out iOS 27.2 on October 26, 2026 (US time; October 27 in Japan). The update brings Japanese support to the "Siri AI" beta, along with stronger responses that draw on past conversations and improved access to personal information. Everyday apps such as Photos sharing and Podcasts playback also get improvements. In addition, the official security notes for iOS 27.2 and iPadOS 27.2 list 163 CVEs (Common Vulnerabilities and Exposures identifiers) after removing duplicates. However, the devices that can install the OS update are not necessarily the same as those that can use the new features, and available features also vary by language setting and connected accessories.
Updating to iOS 27.2 and using Siri AI have different device requirements. For example, the iPhone 15 and iPhone 15 Plus can update to iOS 27.2 but do not support Siri AI. The iPhone 15 Pro and iPhone 15 Pro Max support both. Apple's list of supported models includes every series from the iPhone 11 onward, as well as the second- and third-generation iPhone SE, the iPhone Air and the iPhone Duo.
Siri AI now supports Japanese, with stronger use of past conversations and personal information
According to Apple's announcement, Siri AI now supports five new languages: Japanese, French, Korean, Portuguese and Spanish. Together with English, that makes six supported languages. While iOS 27.2 is a full release, Siri AI itself remains in beta. And the fact that Japanese support has been announced does not mean every Siri AI-related feature is available in Japanese.
The table below summarizes the main changes and conditions of use, based on Apple's update notes, its feature availability page and each device's guide, as checked on October 27.
| Item | Main changes | Conditions and caveats |
|---|---|---|
| iOS 27.2 | New features and security fixes | Even on supported devices, available features vary by model, region, language and carrier |
| Siri AI | Supports five languages including Japanese; improved use of conversations and personal information | iPhone 15 Pro/Pro Max and all iPhone 16 models or later. Requires Apple Intelligence to be enabled and a supported language to be set. Offered as a beta |
| Suggestions in Messages | Suggests actions such as events and reminders based on conversation content | Apple's official feature availability page lists only nine English-speaking regions. Japanese is not included |
| Photos / Image Playground | Embeds SynthID digital watermarks in many AI-generated and edited images | A mechanism for checking an image's provenance; it does not determine whether any given image is authentic |
| iPhone Duo / Shortcuts | Adds automations triggered by opening or closing the Duo; supports Pencil-related features | The open/close trigger is exclusive to the Duo. Pencil models and connection requirements must be checked separately |
| HomePod | Expanded lighting effects and audio integration | Requires a HomePod software update and a supported model. Four-speaker surround also has Apple TV generation requirements |
As this shows, the range of devices differs for the OS itself, for Siri AI, for features available in Japanese and for Duo-only features. Even with the same OS version, not every device gets the same features.
One of the main Siri AI improvements is responding with past conversations in mind. Apple's example is asking later about a restaurant Siri recommended the previous week. Because Siri can refer to earlier exchanges as well as the current question, you don't have to explain the same request from scratch.
Personal information search has also been expanded. In addition to what could already be searched, Siri can now find photos attached to messages, attendees listed on calendar events and the contents of voicemail. Search results drawing on Safari browsing history and the Reading List are also said to improve. In short, the update strengthens both Siri's ability to draw on past conversations and its ability to find information about the user.
Features for controlling what Siri can reference have been added as well. A new "Excluded Apps" setting lets you specify, in one place, apps you want removed from what Siri, search and suggestions can reference. You can also select and copy just the part you need from a Siri AI response, which saves the trouble of copying a long answer in full and then editing it. Both controls over access to information and usability of responses have improved.
Using Siri AI requires a supported device, either an iPhone 15 Pro/Pro Max or any iPhone 16 model or later, with Apple Intelligence enabled and a supported language set. It is not available to users under 13, and regional restrictions apply. According to Apple's update notes, it is not available in the EU on iOS, iPadOS or watchOS, and mainland China is not included.
Some Apple Intelligence features that use server-based models also have daily usage limits. Siri AI is among them, and the limit varies depending on the feature used, the complexity of the request and system demand. Apple says it plans to introduce a paid option to expand usage allowances in the future, but has not disclosed specific usage counts or pricing.
One point to watch with Japanese support is the new feature that suggests actions based on message conversations. For example, a conversation about dinner plans can prompt a suggestion to add an event to the calendar, turning message content into events or reminders. However, as of October 27, Apple's official feature availability page lists the supported languages and regions for "Apple Intelligence: Messages: Suggestions" as nine English-speaking regions only, and Japanese is not included. Siri AI supporting Japanese is not the same as every related feature working in Japanese.
Improved photo sharing, and SynthID watermarks for AI-generated images
In Photos, shared albums are easier to use. You can now edit captions and comments on shared photos after the fact, and accidentally adding the same photo twice is prevented. Reminders can also be shown to participants to save photos and videos before an album expires. The update addresses both fixing descriptions after sharing and forgetting to save important photos.
Another significant change is support for SynthID in Photos and Image Playground. SynthID is an invisible digital watermarking technology developed by Google DeepMind that is embedded in images. According to Apple's iPhone guide, from iOS 27.2 onward, SynthID is embedded in many images generated or edited with Apple Intelligence tools. This gives people another clue for checking whether an image was generated or edited by AI.
Google DeepMind explains that SynthID is designed to withstand modifications such as cropping and compression. Apple also says the presence of the watermark can be checked using SynthID Detector. Unlike methods that place a visible mark on an image's surface, it can embed identifying information without changing how the image looks. However, it is not a technology that guarantees survival of every kind of modification or that the watermark can never be removed.
What SynthID can confirm is, fundamentally, whether a corresponding watermark is embedded. It does not prove that the events in a photo actually happened, and an image in which no watermark is detected cannot be judged authentic. Apple's scope is also "many" AI-generated and edited images, so it is not a system that can identify all AI images.
Podcasts, Games, Apple TV and FaceTime also get usability improvements
iOS 27.2 also brings several changes to everyday apps. In Podcasts, the Home tab now shows "New Episodes" and "Continue Listening" separately. Checking whether a subscribed show has new episodes is now separate from resuming an episode you were partway through, making it easier to reach the content you want.
In the Friends tab of the Games app, you can now see why a suggested friend was recommended. A friend's player page also shows recently played games, making it easier to see what they enjoy. The Apple TV app now supports "Simple Profiles," so people in the same household can each use their own profile and receive recommendations suited to their tastes.
FaceTime has gained the ability to add an external sign language interpreter or a real-time captioner to a call. Bringing human interpretation and captioning support into video calls should improve accessibility. Supported devices also have features that expand how the camera and screen can be used, but these have device-specific conditions.
Automations triggered by opening and closing the iPhone Duo, and new peripheral features
iOS 27.2 adds automations that take advantage of the iPhone Duo's folding design. In the Shortcuts app, the physical act of opening or closing the device can serve as an automation trigger. The Duo's Apple Pencil and FaceTime features also have their own model-specific functions and conditions of use.
Open/close trigger added to Shortcuts, and improved automations when apps close
According to Apple's Shortcuts 27.2 update notes, you can now specify opening and closing the iPhone Duo as conditions for running an automation. This lets you link the device's open and close actions to running a shortcut. Automations triggered by starting a workout now also work with the Fitness app, and in automations triggered when an app closes, the name of the closed app can be passed to subsequent actions.
Editing in Shortcuts has also improved. You can change a shortcut's name and icon directly from the library, reducing the steps needed. The "Use Model" action's ability to retrieve the latest information from the web has expanded its supported languages. However, the update notes do not state whether Japanese is among the added languages. Creating shortcuts from natural-language descriptions and an action that saves data each time it runs were already introduced in iOS 27.
Apple Pencil connection and Duo-only FaceTime features
Apple's connection guide explains how to pair the Apple Pencil (USB-C). Connect it to the device with a USB-C cable and select "Tap to Connect" to complete pairing, and the Pencil charges while connected. However, you need to connect again if you restart the device, turn off Bluetooth or pair the Pencil with another device.
FaceTime includes "Edge Light," which uses the iPhone Duo's inner screen. According to Apple's model-specific guide, the feature brightens the edges of the screen to light your face. You can adjust brightness by changing the width of the glowing area, and you can also change the color temperature. By default, it turns on automatically when the surroundings are dark.
The iPhone 17 and later also support "Dual Capture," which overlays the front camera feed as a small window on the rear camera feed. To use it, every call participant needs iOS 27, iPadOS 27 or macOS 27 or later. Separately, the iPhone Duo has a feature that uses both the inner and outer screens and cameras so that a person next to you can join the call. Both are FaceTime features, but supported models and operating conditions are not the same.
HomePod 27.2 expands lighting effects and audio integration
Around the same time as the iPhone update, HomePod software 27.2 was also released. The newly added "Sound Glow" makes the light on top of the HomePod glow in time with sound, and supports the original HomePod mini, HomePod mini 2 and the second-generation HomePod. Audio from a Mac can now continue playing on a HomePod, and "Lock controls," which disables the touch controls on top of the unit, has also been added.
Meanwhile, four-HomePod surround playback requires a fourth-generation Apple TV 4K. In addition, the front and rear must each have a pair made up of the same model, either HomePod mini 2 or second-generation HomePod. Because Sound Glow and four-speaker surround support different HomePod generations, updating to the same 27.2 does not give you the same features; what you can use depends on your combination of devices. If you combine multiple HomePods in particular, check the model and software version of each device, including the Apple TV.
Security fixes span 163 CVEs, so the update matters even for devices without AI support
The new features in iOS 27.2 are limited by device and language. The security fixes, however, matter even for iPhones that cannot use Siri AI. Apple's security notes for iOS 27.2 and iPadOS 27.2 describe fixes for a wide range of issues, from app access permissions to web content processing.
Counting the CVE identifiers in the official security notes as of October 27 gives 163 after removing duplicates. This figure was calculated by extracting the non-empty cve values from the vulnerabilities array in the JSON data Apple publishes, counting each identifier only once. It also matches the set of CVEs listed in the web page text. A CVE is a public identifier used to distinguish vulnerabilities, and the figure of 163 is neither the number of subheadings in the security notes nor a simple sum of the iOS and iPadOS fixes.
The main fixes include unauthorized access to Bluetooth and the camera, leaks of email addresses and arbitrary code execution through web content processing. Representative vulnerabilities and fixes disclosed by Apple are as follows.
| Component / CVE | Potential impact described by Apple | Fix |
|---|---|---|
| AccessorySetupKit / CVE-2026-84493 | A malicious app may access Bluetooth without user consent | An authentication issue was addressed with improved state management |
| CoreMedia / CVE-2026-86990 | A malicious app may access the camera without permission | Improved access restrictions |
| Mail / CVE-2026-112500 | The original email address may be exposed when using Hide My Email | A logic issue was addressed with improved access restrictions |
| WebKit / CVE-2026-112697 | Processing maliciously crafted web content may lead to arbitrary code execution | A use-after-free issue was addressed with improved memory management |
| Apple Intelligence / CVE-2026-86987 | A remote attacker may access sensitive user data | Improved permissions checking |
These are all different kinds of problems. Some let an app access hardware it is not meant to be allowed to use, while others affect the privacy of email addresses or safety while browsing the web. And the fact that the official notes list 163 CVEs does not mean every iPhone has the same 163 vulnerabilities. The models and OS versions actually affected differ by item, and the count alone cannot be used to judge the risk to any individual device.
The impacts in the table above are problems that could occur through the vulnerabilities Apple disclosed; they do not mean harm has actually occurred. The security notes checked as of October 27 contain no statement indicating that these vulnerabilities were exploited in real-world attacks. However, the absence of reported exploitation does not prove that no attacks exist.
WebKit's CVE-2026-112697 in particular lists the iPhone 11 and later among the models addressed, so it also applies to the iPhone 15 and iPhone 15 Plus, which do not support Siri AI. Whether you can use the Japanese version of Siri AI should therefore not be the only factor in deciding whether to update to iOS 27.2. Separate from the conditions for using new features, applying the security fixes is an important reason to update. On your iPhone, open Settings → General → Software Update and check the version being offered and what the update includes.
