Samsung Galaxy S25 Ultra

SaferProducts.gov consumer incident report 20260609-3059A-2147317389. Severity: No Incident, No Injury. Matched catalog product: Samsung Galaxy S25 Ultra. Incident: On May 7, 2026 at approximately 4:00 AM, after a forced [REDACTED] software update, the Samsung Galaxy S25 Ultra began catastrophic thermal runaway. Developer tools and options were removed. I monitored it closely throughout the day with screenshots and videos as the battery percentage climbed higher and higher, eventually reaching 152%. Camera and USB functions failed. Red warning lights appeared as catastrophic failure occurred. I barely managed to power it off and threw it into the yard for safety. When [REDACTED] County Hazmat arrived, we observed that more than 50% battery had drained while the device was powered off after the runaway. Hazmat classified it as Level 9 Hazardous Material. The county was not equipped to store it as evidence, so the only options were to destroy it or leave it with us. It remains stored safely outdoors as evidence.A second S25 Ultra was delivered via [REDACTED] using a forged signature ([REDACTED]County Sheriff Report #[REDACTED]). [REDACTED]has continued a 39+ day pattern of harassment, sending additional [REDCATED] packages on June 4, 5, 8, and 9, and demanding that I personally mail the hazardous device in its unopened box, despite my repeated written refusals. [REDACTED] had promised a non-Samsung replacement during a May 7 call after the FCC served them (Ticket #[REDACTED]). Every [REDACTED] location and their 800# refused to accept it. The entire household is terrified of the device no one dares touch it. I had to purchase my own safe [

SaferProducts.gov consumer incident report 20260517-8A918-2147319142. Severity: Injury, First Aid Received by Non-Medical Professional. Product: Samsung Galaxy S25 Ultra (Samsung Galaxy S25 Ultra smartphone, Titanium Gray color, 162.8 x 77.6 x 8.2 mm). Incident: On multiple occasions over the last month, my Samsung smartphone -- a Galaxy S25 Ultra -- has experienced severe, recurring thermal runaway events resulting in consecutive battery swelling, expanding the phone's chassis and making the device physically too hot to touch. The issue began with the original battery swelling, causing the back panel to separate. I took the device to an authorized Samsung service partner, [REDACTED], where the battery was replaced with an official OEM part. Within days, that second battery swelled completely up inside the chassis. I returned to the authorized [REDACTED] service center for a second replacement. The third replacement battery is now actively swelling, bloating the chassis, and radiating extreme heat even when idle. It measures at a temperature of 90 degrees C, or 194 F, and caused minor burns to my palm which took several days to heal. Because this catastrophic failure has occurred across three separate, brand-new batteries, the internal charging logic board or power management integrated circuit (PMIC) of the phone is fundamentally defective. It is delivering improper voltage, creating an ongoing fire, explosion, and chemical hazard in my home and workplace. Despite reporting this multi-stage safety loop to Samsung customer service over a two-week period, frontline support agents have repeatedly failed to escalate the issue, dropped communications, and closed my active service tickets without resolution. The device cannot be safely operated, cannot be charged, and represents a significant thermal safety hazard.
