SaferProducts.gov consumer incident report 20260917-33AD9-2147309774. Severity: Incident, No Injury. Product: Samsung SM-S921UZKAATT (Samsung Galaxy S24 128 GB Onyx Black Model number SM-S921UZKAATT Serial number RFCX60FVR1Y, smartphone). Incident: My husbands Samsung Galaxy S24 device suffered a catastrophic thermal failure immediately following a mandatory system update on July 30, 2026. The device experienced rapid battery drain, display glitches, and extreme overheating, causing the lithium-ion battery to physically swell and pop the rear casing off the frame. Over the past 49 days, I have contacted Samsung support 11+ times, generating over seven ticket numbers (most recently Ticket [REDACTED]). Despite fulfilling every requestincluding submitting photos, receipts, and physically bringing the phone to an authorized Samsung repair center on August 18Samsung failed to process the hazard inspection correctly, turned us away, and subsequently insisted we ship a physically compromised, hazardous battery through standard mail. Samsung has refused to offer a direct replacement or a safe local resolution, leaving my husband without a working device during a severe family hardship following his grandmother's passing. I am requesting an immediate replacement device or full financial accommodation for this unserviceable product safety failure.
