we have already reached collective at 10am KST on 23/01 (23:00 BRT since Sunday 22/01), the Samsung finally released the real reason for the explosions. g5i1l
The press conference began with an apology to all those affected. From consumers to partners, Samsung has assured that this will not happen again. It has ensured that extensive investigations have taken place, and the results will help prevent the problem from happening again. Announced in August and ended in October, 96% of all Galaxy Note7s have returned to the company (meaning there are still 4% of them out there). After analyzing both the instrument hardware and the software used, the results were replicated to ensure the accuracy of the analysis. This not only from Samsung, but also from independent analysts.
After thousands of tests, the faulty component was identified: the battery. It helped to Samsung focusing on the problem, but still not discovering the cause of explosions. New tests were performed, with the problem finally identified: the placement of the battery's internal electrodes. In one of the corners, the positive and negative electrodes, because they were crooked, touched each other. In other words, a short circuit (picture below).

There is also a second cause, according to an independent analyst (UL): the battery design itself by an “A company”. The protection in the manufacturing process was insufficient to guarantee protection in the most demanding conditions of use. 
In the case of “company B”, the battery quality itself was low, with several defective components ready to present problems.
Still, the first independent analyst said that more tests will be needed to identify the problem beyond doubt. A second analyst (Exponent) identified a problem in the battery construction of both manufacturers. Each of them had a different defect, but the result is the same: short circuit:
In this case, the problem was the geometry of the placement of the electrodes, which easily touched:
Both independent analysts agree that the high density of the batteries "helped" cause the problem. As the cells are closer, their wrapping (wrongly) made the poles get closer, facilitating the short circuit. The Note7 featured multiple layers of circuit protection. That is, an unofficial charger would not cause a short circuit, since the problem was in the battery itself.
The third independent analyst, representing the German TÜV Rheinland, did not identify relevant problems during the battery components production process. This was during the visit to the factories, where conditions of humidity, temperature and other environmental conditions were analyzed. Even analyzing production and logistics, the company did not identify problems, stating that the samples ed all international safety tests.

Again, Samsung has assured that the problem will not happen again. Initially, the Note7 is designed to use a smaller battery than the 3500 mAh officers (3000 mAh). This in a smaller space, but unfortunately the device "suffered" with defective batteries. The company assumes complete responsibility for the case in question, reaffirming its commitment to improving the robustness of its manufacturing process, as well as choosing third-party manufacturers. More than that, it created a group of battery specialists for the company's future devices.
In the end, the problem is the short circuit, identified by Samsung and confirmed by two independent analysts.. From now on, Batteries will go through an 8-step process to check their safety, among other measures Unfortunately, we have to comment: if these measures were already in place, this situation probably would not have occurred.
