Samsung Galaxy Round
As of Oct. 9, Samsung put a stop to the speculation with its now-official Samsung Galaxy Round (pictured), the first smartphone with a curved, flexible display. According to the Samsung Tomorrow blog , a feature called the "roll effect" allows users to tilt the curved device from a flat position, triggering the display to show basic information such as time, date and missed calls. Returning the smartphone to a flat position turns the display off again. The Galaxy Round is a 5.7-inch device and will be available in Korea beginning Oct. 10.
