Samsung Galaxy Note 7 Controversy: Results of the investigation unveiled
Last August 2017, Samsung, one of the leading smartphone brand launched the Samsung Galaxy Note 7. Samsung had it on sale and available for users who complained of the device to burst into flames.
Samsung announced a replacement program to respond to the needs of the users of the said device.
Why did the Note 7 burst into flames?
Upon initial investigation, 700 researchers from Samsung found out that the issue is caused by the faulty battery manufacturing with one of its two suppliers, not with the Samsung Galaxy Note 7 itself. Samsung then decided to recall Note 7’s and replaced them with new battery.
Unfortunately, most Note 7’s replacement with a new battery have reported to still explode that made Samsung officially issued a recall of the device globally.
Samsung also added three independent firms to conduct their own tests and representatives from each firms were also present on the press conference held in Korea to announce their respective findings.
Since the issue is because of the fault of the two manufacturing companies and not with the Note 7 itself, here are the issues identified:
Issue: Electrode deflection
It is where there is an incorrect positioning of the negative electrode tip in the upper right corner of the battery.
Issue: Abnormal weld spot
This led to an internal short circuit causing the battery to explode
The tests found nothing wrong with the Note 7 itself, its fast-charging feature, iris scanner, water resistance and USB-c connectivity has nothing to do with the issue. Samsung also added that there was an adequate space inside the phone and it could also accommodate a higher battery capacity, and that the speculations that it is because of the swelling of the battery and contract during charging was answered.
Although, despite of the fact that the cause is with the battery manufacturers, Samsung took all the responsibility for the incident. Not just with the battery specifications they have provided to the manufacturers but also for failing to discover the issue that could have been avoided with further testing.
Because of the results of the press-conference, Samsung formed an independent Battery Advisory Council composed of the academics from Berkeley, Cambridge and Stanford.
Samsung also have adopted a new 8-point checklist for testing new products and it includes enhancement to existing processes like the x-ray scans.
Samsung says that they are still committed to an innovation that redefines what’s possible in safety that they will continue to innovate with extra caution next time.
