I bet that at some point one of these two tings have been brought up by engineers within the company:
- - The Note 7 battery has too high a capacity for the space that it occupies. Or serious missgivings about some other technical aspect.
- - The Note 7 battery testing has not been through enough or performed long enough to ensure 100% stability.
Why was this information not passed on? What manager didn't react to it?
This goes way beyond a simple hardware issue.
