Google is testing a branding update for its Messages app, potentially replacing the “G” logo with the full “Google” wordmark in the app's header. This change aligns with a trend seen in other Google applications like Photos, Calendar, and Drive, which already feature the “Google” branding. The update, revealed through an APK teardown, aims to enhance brand visibility and recognition. The transition to the full wordmark reflects a cohesive branding strategy across Google’s platforms, promising a consistent user experience on various devices. The timeline for this change remains uncertain as it may be part of a broader user interface refresh.
