A Hong Kong resident has claimed that his Samsung Galaxy S4 exploded and caught fire in his hands. He then threw the flaming phone onto his flammable sofa, causing it to catch fire as well. This then caused his entire house to burn down. Samsung's local office in Hong Kong said it would analyze chemicals from the scene of the fire to see whether any of them could have come from its factory. Some have speculated that the phone could have caught fire due to the phone containing rogue parts, or that the man was using a fake charger made from inferior materials.
