Many Samsung S4 phones have been exploding off late and if you add two and two together, it just seems that Samsung is using low quality components even in its expensive phones. How this guy narrates the incident is this – his battery exploded into flames and he just happened to chuck it at the couch, which just made things worse and worse. Hong Kong newspaper Xianguo reported this incident. In fact, haven't brands like Toyota recalled many of their products in face of safety concerns? It doesn't even need to be that Samsung exchanges the phones for new or refund the amount paid for them. It just needs to find a fast solution to this problem.
