Samsung has wrapped up its investigation into an incident with the Galaxy Ring, which in the fall of 2025 began to deform on a tech blogger’s finger, causing pain and pronounced swelling. The situation escalated to the point that the owner needed medical assistance to have the device removed.
Early photos and descriptions sparked speculation about a swollen lithium‑ion battery, a familiar risk for ultra‑compact gadgets. But Samsung’s internal probe, conducted alongside independent experts, pointed elsewhere: a crack in the ring’s casing. It was this mechanical damage that altered the device’s shape, rather than a battery failure.
The exact reason the crack appeared could not be determined. The company maintains that the episode is isolated and does not signal systemic safety issues with the Galaxy Ring. Samsung also notes that the device’s design and battery meet all current standards. The conclusion is likely to reassure potential buyers, even if the unknown root cause still leaves an open question.
Introduced as a wearable for sleep and activity tracking, the Galaxy Ring ranks among Samsung’s most compact battery-powered devices. The incident has sharpened attention on the safety of wearables. Samsung says it continues to monitor product quality and strongly encourages users to contact support at any sign of abnormal operation.
