Samsung was riding high.

It's last two releases of smartphone models have garnered rave reviews and strong sales. The Galaxy Note 7 was the latest and greatest.

But a big problem started surfacing soon after release. Dozen of the phones dramatically caught fire. Seems batteries from one of Samsung's suppliers tended to overheat and spark fires. The solution seems straightforward. Have users with the faulty batteries return their Note 7s for replacements. But most Note 7 owners haven't turned in their phones.

What's gone wrong? What owners of this phone need to do now? And how do recalls like this work? Is it always up to the company to initiate the recall and then for the government to be asked into the process?
