Samsung definitively kills off Note 7

Samsung Electronics Co. is ending production of its problematic Galaxy Note 7 smartphones, taking the drastic step of killing off a smartphone that became a major headache for the South Korean electronics maker.After halting sales of the new versions of the large-screen smartphone that failed to fix exploding batteries, Samsung finally pulled the plug on a key product that was supposed to compete with Apple Inc.'s iPhones and other high-end smartphones during the U.S. holiday shopping season.Production will stop, Samsung said in a statement Tuesday.The only right decision.
