Before Samsung has always been different from the supplier of battery module, but did not recall the new generation of flagship products sold in my country, but recently exposed foreign recall and replacing the new battery module, GalaxyNote7 actually there will be battery self-explosion. danger. In particular, when there is a three-star Galaxynote7 take Samsung Galaxynote7, the Galaxynote7 battery suddenly ignited to the fire before the takeoff, but fortunately, the flight attendant immediately arranged passengers to evacuate.

The Samsung Galaxynote7 explosion immediately made Samsung Electronics had to stop producing the equipment and suggesting that the equipment users immediately shut down, and at the same time, my country's National Quality Supervision Administration also officially launched the Distance and Defects of Samsung Electronics. survey. Samsung Electronics finally decided to officially recall all Galaxynote7 sold in my country on October 11, a total of 19,0984 sets (including 1858 sets of recall).

Yesterday, Samsung Electronics had officially released the recall of my country in its official website. It clearly writes this time only to recall Samsung GalaxyNote7 mobile phones, packaging boxes, headphones, chargers or purchases, no need to refund. The compensation method given is that direct return will get a full payment of 200 yuan subsidies, and by replacing Samsung Galaxys7 / S7edge will receive a total of 600 yuan subsidies, and replacement of other models Samsung mobile phone is 300 yuan subsidy.

The non-state GalaxyNote7 can also be refunded in China. It is understood that the non-state Note7 refund amount will remove value-added tax, and after returning 17% value-added tax, the refund amount is approximately 5118 yuan. Samsung this recall regulation is already a good way, after all, I also undertake the GualaxyNote7 recall responsibility of the non-state version.

Specific recalls, you can click on this link to get to see the official website. This Samsung GalaxyNote7 global suspension and recall will become the biggest in the history of smart phones, the most far-reaching recall event. After the official announcement of the recall information this month, Samsung Electronics stock price reached 8.

04%, the biggest drop since 2008. Swiss Bank analysts believe that Samsung GalaxyNote7 will lead to sales of 19 million mobile phones, resulting in less than $ 17 billion revenue losses. At present, Samsung Electronics still indicates that its internal engineers have not found specific reasons for GalaxyNote7 battery explosions.

However, South Korea's SBS TV is published a Samsung Galaxynote7 internal battery structure. From the picture, you can see the battery module supplied by SDI for separating the yin and yang pole battery isolation plate may be close to the glass rear cover close to Samsung back. Different degrees of bending.

Original Samsung GalaxyNote7 is a sold point in a parallel surface, its front is a surface screen, behind the glass rear cover in order to better feel and look, using the design of the curvature of the surface screen. However, it is also because this design defect has caused the battery module to extrusion deformation during installation, and finally, the isolation board collapse causes the battery short circuit self-ignition explosion. During the first Samsung Global Recall, South Korea's consumer protection agencies have leaked a document, and the document indicates that the GalaxyNote7 battery module produced by Samsung's subsidiary SDI is slightly more than the battery module produced by ATL.

Naturally there will be tolerances when assembled, causing the battery and the curved glass rear cover too close, it is possible to deform the inside of the battery. If it is easily caused by external force, it is possible to spontaneously combustion, plus Samsung GalaxyNote7 dust-proof waterproof, pressure accumulation can also explode in the body. As for why the ATL battery supplier will still appear, the analysis is still because the curved glass rear cover is designed, and the dismantling of IFIXIT We can see the Battery of Galaxynote7 very close to the metal box.

Although the parts layout of most smartphones is the same, because the design of GalaxyNote7 double curved glass, the metal border is thinner than the thickness of the body, so there is no way to protect the battery module when the fuselage is bent. Accident that causes battery spontaneous combustion. After Samsung enables the recall of the global, the US Department of Transport has issued a statement, which clearly prohibits anyone to carry Samsung GalaxyNote7 mobile phones in the United States or go to the United States, and cannot be placed on the carry-on baggage or consignment.

Cargo to transport. At present, the equipment has been included in the "Federal Dangerous Goods Act" to be banned, once found to carry GalaxyNote7 take the plane, then it may be confiscated mobile phone. The United States federal express and UPS also announced Samsung GalaxyNote7 mailing guide, and users must place the device in a special box specifically for transportation of lithium-ion batteries, and can only be shipped by land transport.

In addition, federal express will not accept GalaxyNote7 transport orders for personal customers or other retail stores. Samsung also also said that it will supply special fire boxes to the US users to facilitate consumers' safety returns. There are also strict instructions in the fire prevention box.

Users must first put the phone into the electrostatic bag and put it in the small box, then put the phone into the medium-sized box with ceramic fiber lining, and finally load the large box to land. Way to send it back. The protection of the four layers of the foot dare to send the user to send it, it can be seen that this Samsung is also very afraid will continue to appear GalaxyNote7 self-explosion incident.

This frequent explosion has seriously affected the credibility of Samsung Electronics in the hearts of consumers, and the impact of recall incidents is extremely far-reaching. A survey said that nearly 40% of Samsung mobile phone users will never buy Samsung brand mobile phone, Samsung is now on the front of a reputation. If you want to retrieve the trust of the consumer, Samsung Electronics should be positive, quickly find the reason why GalaxyNote7 spontaneous combustion is not concealed to publish it to consumers.

Originally sent to the new generation of Samsung Android, the new generation of Samsung, the media, and market reputation sales, has been recalling and discontinued after two months, Samsung Galaxynote7 has become the shortest life of history. Samsung Electronics also said that the recall of GalaxyNote7 will be processed, and will not be renovated or repaired. This time, Samsung GalaxyNote7 really has completely closed, no longer see.
