Galaxy Watch 4 update brings camera zoom controls and more to the older smartwatch

Samsung announced an update for the Galaxy Watch's Camera Controller app early this month to give users access to zoom controls on the smartwatch. The update arrived with firmware version R910XXU1AWA3 for the Galaxy Watch 5 shortly after the announcement, bringing camera zoom controls, January 2023 security patches, and a new device diagnostics tool to Samsung's latest Wear OS smartwatch. Samsung has now started rolling out a similar update for the older Galaxy Watch 4.
