Following widespread recall.

In September 2016, over 51,000 Galaxy Note7 smartphones were recalled by Samsung. Four months later, Samsung announced the cause of the Galaxy Note7 incidents was due to a fault in the design and manufacturing of the devices’ battery via a press conference held in Seoul, South Korea.

In his address, Samsung president of mobile communications, DJ Koh said:

“I deeply apologise to all of our customers, carriers, retail and distribution partners. We thank you for your patience and continuous support. We believe that as a first step to regain your trust, it is important to provide a thorough understanding of the cause behind the Note7 incidents and our plan to take preventative measures.”

The Galaxy Note7 launched globally on August 19, 2016. Two weeks later, on September 2, Samsung announced a global product replacement program. The device was discontinued on October 11.

“We are grateful to Note7 owners, carriers, retail partners and business partners for their help to expedite this process and achieve this exceptional return rate,” Koh said.

Over 700 Samsung researchers and engineers analysed more than 2,000 fully assembled Galaxy Note7 devices and more than 30,000 Galaxy Note7 batteries. These were subjected to repeated charge and discharge testing.
