Google has begun testing an edit function in its Google Messages app that allows Android users to modify Rich Communication Services (RCS) texts after they have been sent to iPhones. The capability, spotted by Android Authority and detailed by TechRadar and other outlets, is appearing for a small subset of Google Messages beta users. The feature draws on the new RCS Universal Profile 3.0 and mirrors the 15-minute window that already applies to message edits within Android-to-Android and iOS-to-iOS conversations. On Android devices the revised text replaces the original, but iPhone recipients currently see a follow-up message preceded by an asterisk because Apple’s Messages app has not yet adopted the display protocol. Editing remains one-way for now—iPhone users still cannot alter RCS messages sent to Android devices. Google has not provided a timetable for a wider release, and the function is expected to work properly on both platforms only after Apple updates iOS. The trial is part of a broader push by Google and Apple to improve encrypted, feature-rich cross-platform messaging following Apple’s adoption of RCS in iOS 18.
