While announcing the results, the South-Korean giant said that it probed into all aspects of Galaxy Note 7 that include a thorough scrutiny of its software, hardware, assembly processes and much more.
It took around 700 engineers, 200,000 Note 7 devices, and 30,000 batteries to get the tests done with a view to finding the exact cause of overheating batteries and thermal failures.
Samsung said that Note 7 was in no way responsible for the battery failures. And, whatever happened was strictly a battery issue.
The Note 7 handsets were replacing with batteries, either made by Samsung SDI, or Amperex Technology, a Hong Kong-based company. In the recent tests, Samsung has found faults with both the batteries.
Taking a cue from the recent explosions of Note 7 batteries, Samsung is relying upon a string of stronger protective measures, including 8-point battery safety check, to create robust cellular products for its users.
