Although a number of evaluation agencies have given an analysis of the security risks of Samsung Note 7, people are generally more concerned about Samsung's final conclusions and performance attitudes in this incident. On the 23rd of this month, Samsung will announce more findings on the safety hazards of GALAXY Note 7 in Korea. Samsung had previously blamed the battery design, but Samsung’s director, Park Sung-hwan, who was responsible for battery research, made it clear: “Samsung prematurely attributed the cause of spontaneous combustion to batteries. I don’t think there is any problem with the battery, or it’s not a major problem.†He also said that the "complexity" of the Samsung Note 7 mobile phone has not been able to find the root cause of the spontaneous combustion of the mobile phone for such a long time.
In December 16th, a third-party agency gave an evaluation report that the real reason for the Samsung Galaxy Note7 explosion was that the internal space design of the fuselage was too bold, and the safety space reserved for the battery was too narrow. There is a certain probability that the battery will expand, and the back cover of the mobile phone will squeeze the battery at the same time, causing the positive and negative materials of the mobile phone battery to be separated, the electrolyte will become hot, and thus the mobile phone battery will be heated and burned, even The event of the explosion.
The Korean media news1 lists five reasons that may cause the explosion of the GALAXY Note 7 battery, including errors in the temperature control system of the battery, problems with the design of the USB-C interface and the fast charging function, and high-performance applications such as iris recognition. Errors occurred during the loading process, problems with the overall design of the mobile phone, and user habits.
After the number of Note 7 security incidents, Samsung launched a global recall on September 2 and gave compensation measures. However, the Chinese region did not synchronize but it was not until October 11 that it apologized and recalled it. It was more than a month late. As for the payment, Samsung will stop the compensation for the recall of Note 7 users from January 1. On January 10th, Samsung said that it has recalled more than 96% of the Galaxy Note7 worldwide. And a small number of Note 7 became a hot item, and a second-hand trading platform even sold a high price of 8,000 yuan.
