The LTE Samsung Galaxy Watch is getting an overdue One UI update | TechRadar. My daily driver Smartwatch, the LTE variant of the Galaxy Watch by Samsung, is finally getting the new One UI update, and it is great. One tap wakeup. Active Swim information. Heart rate notifications if my heart rate reaches a level I can set. Even better battery life; although, I can get two days already with time to spare. New watch faces. Easier access to Settings. All in all, the best Smartwatch is getting better.
