A South Korean user says a Samsung Galaxy S24 suddenly caught fire during everyday use, in what appears to be a rare but serious phone fire incident. According to a report cited by SamMobile, the user shared the case on Reddit and said the device was not charging when the accident happened.
That detail matters because unexpected smartphone fires are uncommon, and when they do happen, they are often linked to damaged batteries, physical impact, or charging-related stress. In this case, the owner said none of those typical warning signs were present before the event.
The Reddit post says the incident took place on May 11, 2026. The user claimed the Samsung Galaxy S24 began smoking out of nowhere while it was being used normally for web browsing. After that, the battery reportedly swelled, the phone became extremely hot, and it then exploded. The owner said the accident caused minor burns and blisters.
According to the account, the phone was not connected to a charger at the time, had not been dropped, and had never been repaired or opened. Fire responders who arrived at the scene reportedly determined that the burn pattern was consistent with spontaneous ignition from a lithium battery. While lithium batteries can catch fire, that usually happens after damage or abnormal stress, and intact cells are generally considered stable.
So far, Samsung has not made a public statement on the case. The user said staff at Samsung headquarters had instructed the head of a local service center to get in touch, suggesting the company may retrieve the device for a technical review. That kind of battery investigation would likely be necessary before any firm conclusion can be made about the cause.
At this stage, the available information still comes from the owner’s account rather than an official fault analysis. Even so, the case is drawing attention because the reported failure pattern looks similar to battery-related damage despite the user’s claim that the handset had not been physically compromised beforehand.
Until Samsung or an independent examination provides more detail, the incident remains an allegation rather than a confirmed product-wide issue. Still, it is the kind of report that will be closely watched given the broader conversation around battery safety in modern flagship phones.
