Anyone who remembers Samsung's infamous bout with bad battery problems in the Galaxy Note 7 will likely have some unwanted flashbacks when they hear the latest news. Launched last year, Samsung's Galaxy Ring was the company's next big push into wearable tech, meant to compete with the likes of Oura and other smart ring companies. However, Galaxy Ring owners might have a new issue to worry about, as one user has reportedly been hospitalized following battery swelling problems with Samsung's smart ring. Rotar shared photos of the Galaxy Ring on his finger in a post on X, noting that the battery began to swell just before he was meant to board a flight to Hawaii.
