Samsung is phasing out its native Messages app in favor of Google Messages, with the complete transition expected by the end of July. After this date, users who have not switched may be unable to send or receive messages through Samsung Messages. The change primarily affects users still using Samsung Messages as their default app, while those already on Google Messages will likely notice no difference. Samsung's move aligns with a trend towards a unified messaging platform that supports Rich Communication Services (RCS), enhancing SMS features. Existing messages and contacts should transfer to Google Messages, but users are advised to back up their devices beforehand. Most recent Samsung Galaxy devices support Google Messages, but older devices may require a manual download. Users are encouraged to switch to Google Messages early to minimize disruptions.
