Samsung shares plunge over smartphone explosion debacle

Samsung shares plunged Monday after the South Korean electronics giant urged global consumers to stop using its Galaxy Note 7 smartphone due to a spate of exploding batteries that raised alarm around the world. Samsung Electronics on September 2 had announced a recall of its oversized "phablet" after faulty batteries caused some handsets to burst into flames during charging. The US Consumer Product Safety Commission Friday urged Note 7 owners to stop using the device.
