Overview

• Tech YouTuber Daniel Rotar said his Galaxy Ring’s battery expanded while he was wearing it, leaving the ring stuck and causing pain.
• Airport staff in Frankfurt denied him boarding over safety concerns, and hospital clinicians removed the ring using ice and medical lubricant, with no lasting injury reported.
• Images show interior deformation consistent with lithium‑ion cell swelling, a known but uncommon failure mode in compact wearables.
• Samsung says it is in direct contact with Rotar, has collected the ring for forensic analysis, and covered his hotel and ground transport.
• The incident renews scrutiny of the ring’s non‑replaceable battery and follows isolated social reports of swelling or rapid battery drain.
