Galaxy A15 SM-A156UZKXAU

SaferProducts.gov consumer incident report 20250730-0A254-2147329091. Severity: No Incident, No Injury. Product: Galaxy A15 SM-A156UZKXAU (A smartphone battery that began to swell significantly, causing the phones rear casing to no longer fit properly. The device was kept in a protective case and used for typical smartphone functions such as communication, browsing, and app usage. The issue was noticed due to the tight fit of the case becoming misaligned, and upon removal, visible battery swelling was discovered. This occurred without any prior physical damage, overcharging, or misuse.). Incident: I purchased a Samsung Galaxy A15 approximately 10 months ago, and recently noticed the case was no longer fitting properly. Upon inspection, I discovered that the battery had begun to swell, pushing against the internal structure of the phone. The device was being used as a regular personal smartphone by an adult user and was always kept in a protective case with no water damage or drops. It suddenly became unresponsive and would no longer power on. Additionally, the fingerprint sensor/power button stopped functioning around the same time, which I now suspect was due to the battery swelling and warping internal connections. There were no immediate injuries, but the swelling posed a significant fire and safety risk. If I hadnt caught the tight case fit and opened the case to determine the cause, the issue could have escalated dangerously through continued use. I am very tech-savvy and regularly work with servers and electronics, and I almost missed this thats concerning. This kind of failure after less than a year of normal use raises serious safety and quality control concerns.
