On August 19, the Samsung Galaxy Note7 launched in its home country of South Korea and has sold 400,000 units since then. But now Samsung has stopped deliveries to the country's three major carriers - SK Telecom, KT and LG Uplus. A Samsung official only said that the company is checking if deliveries have indeed stopped. One theory states that this is related to several incidents of a Note7 exploding during charging - 5 people have made this claim over the last week. Photos have been posted on Internet forums, though obviously a more serious investigation into the matter is needed...
