One of the biggest mysteries of 2016 will come to an end sometime this month. Samsung will make public the results of its months-long investigation into what caused several Galaxy Note 7 smartphones to turn into flames later this month, according to a report on Reuters. From the report: The South Korean firm said in October it was examining all aspects of the phone, suggesting there may be a combination of factors that contributed to one of the costliest product safety failures in tech history. Samsung has also previously noted that it was working with several third-party sources and experts to figure out what could have caused the error. A popular theory among many is that Samsung attempted to further slim the form factor of the Galaxy Note 7, which resulted in the battery to be held too tightly within the device -- which in turn, caused the layers of lithium cobalt oxide and graphite to touch.
