Samsung blaming a battery problem for problems that led to a massive smartphone recall.

FOX's Rich Denison reports:

Design and manufacturing flaws with batteries are behind Samsung's Galaxy Note 7's tendency to overheat and burst into flames. That's according to officials with the smartphone maker, who say the batteries didn't fit properly in the devices, and they lacked proper insulation.

Samsung admits it's ultimately responsible for identifying the problem before it became a global issue. The worldwide recall of more than three million Note 7 phones is expected to cost Samsung well over five billion dollars.

The company says it's now preparing for the release of its next generation of Galaxy smartphones.
