This incident happened back in 2019, but it seems that due to Apple allegedly failing to take notice of the situation, De Rose has since decided to file a lawsuit against the company. According to De Rose, he noticed a pain in his leg and heard a fizzing sound coming from his pocket.
There was an accompanying popping sound and after he felt a sharp pain on his thigh, he realized that it was coming from his phone. He took his iPhone X out only to find black smoke coming out of it. According to De Rose, he had reached out to Apple multiple times since then but has not gotten a response, which is why he has decided to file a lawsuit.
It is unclear why De Rose’s iPhone X exploded as there could be a number of reasons, but it should be pointed out that exploding iPhones or smartphones in general aren’t very common, so you probably shouldn’t get too worried just yet.
