Samsung Electronics has assured users of its Galaxy S7 and Galaxy S7 Edge phones that the devices are safe following unconfirmed reports of battery explosions. In a statement posted to its website, the company said it stood behind the “quality and safety” of the devices, adding that there had been no confirmed cases of “internal battery failures” among the devices being sold in the North America.

“However, we have confirmed a number of instances caused by severe external damage,” the company said. “Until Samsung is able to obtain and examine any device, it is impossible to determine the true cause of any incident.” The company has also previously sent pop-up messages to Galaxy S7 devices assuring users that the handsets will not be recalled, according to NDTV.

On November 13, the Winnipeg Sun reported that a man received second- and third-degree burns to his hands after his Galaxy S7 exploded when he took it out of his pocket. Similarly, a resident of Ohio in the United States filed a lawsuit against Samsung after his Galaxy S7 Edge reportedly exploded while inside his pocket in May.

On October 27, the company posted posted a 30% drop in its operating profits, which was largely attributed to the two recalls of the company’s premium Galaxy Note7 mobile because of battery issues. The operating profit of the company’s mobile division fell nearly 98% as a result of the recall. Samsung had launched the Galaxy Note7 in South Korea on August 19, but it was forced to declare an international recall of 2.5 million units in September following several reports of the phone exploding.
