Samsung is transitioning from its Messages app to the Google Messages app on Galaxy devices, encouraging users to migrate for a smoother experience. The switch is not mandatory, but Google Messages offers advanced features like Rich Communication Services (RCS) and end-to-end encryption. Migrating from Samsung Messages to Google Messages is simplified, requiring just a few taps without losing existing messages or chat history. Users should ensure Google Messages is installed and that they are logged into the same Google account used with Samsung Messages. The migration process involves launching Google Messages, setting it as the default app, and confirming the change. If old messages do not sync, users should check their internet connection and ensure they are using the correct Google account.
