苹果于当地时间10月26日发布iOS 27.2正式版，为旗下首款折叠屏手机iPhone Duo带来Apple Pencil手写笔支持，同时新增名为Edge Light的面部补光功能。此外，此次更新还涉及Siri人工智能功能、照片应用、FaceTime视频通话以及多款系统应用，苹果也同步推出了macOS、watchOS、visionOS、tvOS和HomePod的软件更新。
Apple Pencil支持是此次iPhone Duo更新的重点之一。苹果此前曾承诺，将在2026年晚些时候为这款折叠屏手机加入Apple Pencil兼容性，如今随着iOS 27.2发布，这项承诺正式兑现。借助折叠屏展开后的大尺寸显示区域，用户可以利用手写笔进行书写、绘图和其他精细操作，使手机在部分使用场景中更接近小型平板电脑。
iPhone Duo采用7.6英寸内屏和5.4英寸外屏。苹果针对这两种不同尺寸的屏幕重新设计了iOS 27的部分控制界面，希望让用户在折叠和展开状态下都能获得相对连贯的操作体验。对于需要手写笔输入的用户而言，更大的内屏能够提供比传统直板手机更充裕的书写空间，也为笔记、标注和图形创作等应用创造了更多可能性。
不过，Apple Pencil兼容性的具体适用范围仍取决于设备支持情况以及应用自身的适配程度。手写笔的加入并不意味着所有iPad应用都能直接运行在iPhone Duo上，开发者仍需要针对折叠屏的显示比例、交互方式和系统界面进行优化。
苹果此次还为iPhone Duo加入Edge Light功能，主要用于视频通话时改善用户面部的照明效果。该功能可以在屏幕边缘产生补光效果，帮助用户在环境光线不足的情况下让面部看起来更加明亮。对于经常在室内、夜间或光线复杂的环境中进行视频会议的用户而言，这项功能有望改善画面观感。
iOS 27.2也进一步扩展了Siri人工智能功能。更新后，Siri AI能够在信息应用中提供建议操作，帮助用户根据消息内容更方便地采取后续行动。同时，苹果扩大了相关人工智能功能的语言支持范围，新增法语、日语、韩语、葡萄牙语和西班牙语。
照片应用和Image Playground也将获得对GoogleSynthID人工智能水印技术的支持。SynthID用于在人工智能生成的内容中嵌入可识别的标记，相关检测能力有助于判断图像是否包含这种水印。不过，这并不意味着系统能够识别所有人工智能生成的图片，检测结果仍取决于内容是否使用了兼容的水印技术。
其他应用也迎来了一系列调整。iPhone上的Apple TV应用新增用户个人资料功能，让不同用户能够更方便地管理各自的观看体验。Apple Podcasts则调整了原有的“接下来播放”队列，改为突出显示“新节目”和“继续播放”两个区域，以便用户查找最新播客和接续尚未听完的内容。
Apple Music也在此次更新中采用了新的应用标志。与此同时，FaceTime群组通话新增双摄像头捕捉功能，用户可以在通话中同时展示前置摄像头拍摄的自拍画面和后置摄像头所记录的场景。这对于需要一边露脸、一边展示周围环境、实物或工作过程的用户尤其有用。
在手机系统之外，苹果还发布了macOS 27.2 Golden Gate、watchOS 27.2、visionOS 27.2、tvOS 27.2以及HomePod 27.2更新，继续推进旗下不同设备的软件迭代。
总体而言，iOS 27.2既是一次常规系统功能更新，也是苹果进一步完善iPhone Duo折叠屏使用体验的重要一步。Apple Pencil支持增强了设备在手写和创作方面的潜力，Edge Light则针对视频通话这一日常场景提供了新的功能。不过，折叠屏设备能否真正发挥大屏优势，仍然取决于应用适配进度、系统交互设计以及开发者能否持续推出针对性优化。

Apple, in the official version of publishiOS 27.2 on October 26, local time, brought Apple Pencil handwritten support for iPhone Duo, the frontal lighting function called Edge Light, to the front of the flag. In addition, the update covered Siri artificial intelligence functions, photo applications, FaceTime video calls and multiple system applications, and Apple synchronized software updates with MacOS, WatchOS, VisionOS, tvOS and HomePod.
Apple Pencil's support is one of the priorities of this iPhone Duo update. Apple had promised to add Apple Pencil to the folding screen phone later in 2026, and that commitment had now been honoured with iOS 27.2publish. The large size of the display area, which is extended by the folding screen, allows users to use handwritten pens for writing, drawing and other fine operations, bringing their mobile phones closer to small tablet computers in partial use.
iPhone Duo uses a 7.6-inch inner screen and 5.4-inch outer screen. Apples have redesigned part of the control interface for iOS 27 for these two different size screens in the hope that users will have relatively consistent operational experience in folding and spreading. For users who need to enter a handwritten pen, a larger inner screen provides more space for writing than traditional straight-board mobile phones and creates more possibilities for applications such as notes, labels and graphic creation.
However, the specific scope of application for the compatibility of Apple Pencil still depends on the support of the equipment and the suitability of the application itself. The addition of handwritten pens does not mean that all iPad applications can run directly on iPhone Duo, and developers still need to optimise the representation, interaction and system interface for folding screens.
Apples this time added the iPhone Duo to the Edge Light feature, which was used mainly to improve the lighting of the user ' s face during video calls. This function can have a lighting effect on the edge of the screen, helping users to make their faces more visible when the environmental light is insufficient. This feature is expected to improve visual perception for users who often conduct videoconferences in indoor, night or light complex environments.
iOS 27.2 has further expanded the Siri artificial intelligence function. Upon updating, Siri AI is able to provide recommended operations in information applications to help users follow up more easily on the content of messages. At the same time, apples have expanded language support for artificial intelligence functions, adding French, Japanese, Korean, Portuguese and Spanish.
Photo applications and Image Playground will also receive support for GoogleSynthID artificial smart watermarking. SynthID is used to embed identifiable markers in artificial intelligence-generated contents, and relevant detection capabilities help to determine whether the image contains such watermarks. However, this does not mean that the system is able to identify all images generated by artificial intelligence, and the results are still dependent on the use of compatible watermarking techniques for content.
A number of adjustments have been introduced for other applications. Application of the Apple TV on iPhone to add a user profile that allows different users to manage their own viewing experience more easily. Apple Podcasts adjusted the original “second play” queue to highlight the two areas of “new programming” and “continue to play” so that users can search for the latest podcasts and follow up on what has not been heard.
Apple Music also introduced new application symbols in this update. At the same time, the FaceTime group calls with a dual camera capture feature, where the user can display both the self-censored images taken by the front camera and the scene recorded by the rear camera. This is particularly useful for users who need to show their faces while showing their surroundings, objects or work processes.
In addition to the mobile phone system, apples have updated publish MacOS 27.2 Golden Gate, WatchOS 27.2, VisionOS 27.2, tvOS 27.2 and HomePod 27.2 to continue to advance software over different devices under the flag.
Overall, iOS 27.2 is both a routine system feature update and an important step in the apples further refining the iPhone Duo folding screen experience. Apple Pencil supports the enhancement of equipment ' s potential in hand writing and creation, while Edge Light provides new features for the daily video call. However, the real ability of the folding screen equipment to take advantage of the large screen still depends on the pace of application adaptation, the interactive design of the system and the sustainability of targeted optimization by developers.
