Samsung Electronics said Wednesday its latest Galaxy Note 4 smartphone will go on sale in China and South Korea later this month as they compete with the sales from Apple's new iPhones. Apple's iPhone 6 has yet to arrive in China and with new larger screens, it eliminates a key advantage for Samsung that lured buyers in with the big screens of its Galaxy phones. The Galaxy Note 4's display measures 5.7 inches diagonally, slightly larger than the biggest iPhone. The Note series comes with a stylus that Samsung calls 'S Pen' for note-taking and drawing. Samsung's president of mobile sales and marketing, Lee Don-joo says, 'The tough situation for Samsung is temporary and Samsung will quickly revive its business.' Samsung is scheduled to give an earnings preview early next month. Its shares have sunk to a two-year low this week.
