We all know the sad story of the exploding Samsung Galaxy Note7 that lived a very short life and got recalled and discontinued due to safety concerns.

Initially, Samsung had blamed a battery supplier for the issue, but as it later turned out that wasn't the case and the company struggled to find the exact cause.

Samsung committed to investigating and revealing the cause of the issue by the end of the year, and it seems that the Korean maker is set to make good on that promise.

The internal investigation is apparently complete and Samsung has sent the findings report to the Korea Testing Laboratory and UL (an American safety organization), among others. The report is, however, yet to be released to the general public (us included).

Meanwhile, Instrumental suggested that extremely tight internal margins were the reason for the exploding batteries, but that remains to be confirmed by Samsung's own analysis.
