When Samsung recalled the Galaxy Note 7 for the first time last month, it said that the explosions were caused by a battery cell defect and that the replacement units it will send out won't have the same issue. When it became clear that replacement units have a similar issue the company decided to kill the Galaxy Note 7 altogether. It's yet to explain what's the cause behind these recent explosions and now all sorts of theories are floating online. Samsung has now said that it's going to explain precisely what went wrong with the Galaxy Note 7 “in the coming weeks.”
“The replacement phones have batteries from a separate and different supplier than the original Note 7 devices. We’re currently conducting a thorough investigation, and it would be premature to speculate on outcomes. We will share more information in the coming weeks,” said Samsung in an official statement.
Recent reports suggest that there might be another battery flaw that made its way to the production line. One theory is that the fast charging feature is behind this. Samsung is reportedly still clueless about what caused replacement units to explode, it's said that the company's engineers have not been able to replicate the issue in the lab as of this week even though they have conducted just about every stress test on the device. Until Samsung gives an official explanation about this we will continue to hear more theories and that's not necessarily a good thing.
