Note 7 may have been a victim of its design
 

The latest theory as to why the Note 7 had battery problems suggests that its rather cool thin design made it go bang.


The Note 7 had an absolutely "symmetrical" design as the glass backplate is sloping towards the metal frame with the same curvature as the display at the front.
But according to Phone Arena that design might have put pressure on the unorthodox battery plates.
