As writes "Wall Street Journal" Samsung probably made a mistake by replacing broken Note 7 for the other phones. About 30% of devices was working correctly. When other phones began to explode it became clear that the battery is not the only reason for the explosion of mobile. There are rumors that the explosions may be caused by the motherboard.
Samsung found a solution to this problem as a priority objective, which according to the company's employees may delay launch of Galaxy S8 for an unspecified amount of time - said to be about two weeks.
