Samsung has been investigating the root cause of overheating issues that forced the company to recall and eventually end production of the Galaxy Note 7. But the company isn't ready to share the final reasons with the press, according to reports in Korean Media. According to a report in The Investor, Samsung has completed its internal investigation and sent the findings to external laboratories including the Korean Testing Laboratory and UL. There have been lot of theories surrounding the exploding Galaxy Note 7. Samsung originally blamed a minor manufacturing defect in the Galaxy Note 7 as the reason that was causing the phones to heat and explode in some cases. Due to overheating issues and fires, more than 2.5 million units of the Galaxy Note 7 were recalled before the product was discontinued just two months after its launch in August. Samsung has previously said that it would share the results of its own finding before the end of the year, but has not disclosed anything so far. Reports also indicated how Samsung's own employees and engineers were unable to figure out the exact cause of the problem when the first recall took place towards the end of September. Soon after the second batch of phones also started exploding, and Samsung was eventually forced to issue a global recall and then end production for the phone. The phone still remains banned from flights across the world.

Meanwhile, the new report from 'The Investor' also notes that Samsung is currently not happy with its own employees over the increasing cases of product leaks. "I feel deeply regretful to hear news of the recent attempts at data breach and prototype leak," said Koh Dong-jin, Samsung’s mobile business chief in an internal memo to employees. “Samsung had a bitter experience due to the leak of important data - on product design and business strategies - to China and consequently suffered damages in the past,” he added. Samsung is rumoured to launch its next-generation smartphone aka the Galaxy S8 in the first half of next year, possibly in February at MWC 2017. Multiple reports suggest Samsung will launch the Galaxy S8 with an all-new design and a bezel-less display. Samsung's new Galaxy S8 will also come with a new virtual-assistant from the company.
