Samsung has started distributing new updates to the Galaxy Watch and Galaxy Watch 3. The company has called the updates R80xXXU1FUD1 and R84xXXU1BUD1, respectively, although Samsung will replace the lowercase 'x' depending on your smartwatch's model number and the region in which you purchased it.
Both updates are relatively small and are downloadable via the Galaxy Wearable app. According to their changelogs, Samsung has improved Messaging app and Wi-Fi stability, along with general system reliability and stability improvements. Overall, this month's update is a comparatively small one, especially compared to the one that Samsung issued in February.
Please note that your Galaxy Watch or Galaxy Watch 3 must have at least 15% charge before the Galaxy Wearable app starts transferring the update. If your smartwatch is not eligible for R80xXXU1FUD1 and R84xXXU1BUD1, then it should be within the next few days.
