However, Wall Street Journal reported that the company will implement the “exchange programs” in 10 countries. It will take them two weeks to replace all the faulty Galaxy Note 7 with a new one.

Meanwhile, it must be a big lesson for Samsung. As a result. They are now conducting intensive battery tests for the units that they will distribute.

The test will commence on Sept. 19. On the other hand, the report stated that the incident caused the company around 3% loss of shares in South Korea.
