The One UI Watch 4.5 beta program for the Galaxy Watch 4 series was launched by Samsung a few months ago, and it appears that testing went well because the company recently announced the beta program’s closure on its community forums. As a result, the Korean conglomerate won’t be releasing any more beta builds for the Watch 4 series. Although Samsung made no announcements on the availability of the One UI Watch 4.5 stable update, some customers have already begun to receive it on their Galaxy Watch 4.
The upgrade weighs in at roughly 95MB and has firmware version R870XXU1GVH2/R870OXM1GVH2. If the update hasn’t yet been applied to your Galaxy Watch 4, you may manually check for it by going to the menu located at Galaxy Wearable > Galaxy Watch4 > Watch4 settings > Watch software update.
