Samsung is still trying to deal with consequences of the incident with spontaneous explosions of Galaxy Note 7 phablet.

Recently, the South Korean vendor explained that was the reason for such a serious defect.



Why did Galaxy Note 7 explode?
Deflagration of Galaxy Note 7 is caused by a small manufacturing defect in the battery, reports Bloomberg referring to Samsung’s report prepared for Korean regulators. Plates in the accumulator experience pressure, which leads to a contact between the positive and negative poles, resulting in excessive heat generation and bridging of contacts.

The company's report states that this is a preliminary assessment, and a more thorough analysis will determine exact causes of the fire. Samsung representatives have promised to eliminate the defect before the end of the investigation.

For those who have not yet had time, or did not want to return the device, Samsung announced release of updated software, which will reduce the risk of battery explosion. The update limits charging Galaxy Note 7 battery only to 60%, thus preventing overheating.

To date, media reported about 35 cases of fire occurred in Galaxy Note 7. 17 of them are marked on Samsung's home market - in South Korea. Samsung has already launched an advertising, which calls to update the device.

Release of the update for overseas users has not been announced yet. There is also no information whether Samsung will resort to forced, that is, regardless of the user's wishes, firmware upgrade.

In the coming days, Samsung plans to release new Galaxy Note 7, the battery of which will not overheat, according to the company. Media reports, citing a well-informed representative of the company, all the replaced batteries "will be marked with yellow alert sticker, applied instead of the previous white on the faulty smartphones."

The main supplier of batteries for Samsung Galaxy Note 7 smartphones will be Chinese company Amperex Technology Limited (ATL), Reuters reported citing a source familiar with the situation. According to him, ATL will take up delivery of batteries in the nearest time. The company has already received orders for additional batteries for Galaxy Note 7, the source said.

Earlier, Samsung’s stock quotes experienced the strongest drop in eight years. They fell more than 10.61%, and on Monday, September 12 at the close of trading on the Korea Exchange in Seoul were worth 1,465,000 won per share. According to Bloomberg’s calculations, the drop in prices means that the South Korean vendor’s market capitalization decreased by $ 22 billion for the two days.
