That being said, it seems that the investigations has apparently come to a close. A report from The Investor (via SamMobile), they have learnt that Samsung has apparently finished with the investigation into the Note 7’s issues. They have also reportedly shared their findings with outside labs, such as Korea Testing Laboratory and UL, but they have yet to make their findings public just yet.
It is possible that they want to verify their findings with third-party sources before making that information known. During the early part of the entire fiasco, Samsung has apparently mistaken the issue as the battery of the Note 7 being at fault as it was later discovered that phones were still exploding even after changing the battery.
However later a report from a third-party website suggested that it was the “aggressive” design of the Note 7 that caused the problems, but like we said Samsung has yet to share their findings so we’re not sure what the real reason could be yet, but since we’re more than halfway through the last month of the year, we probably won’t need to wait too long for the results.
