A BlackBerry smartphone with a square 4.5" screen that eliminates flipping from portrait to landscape mode to view more horizontal content. Introduced in 2014, the Passport also runs Android apps from the Amazon Appstore. The three-row physical keyboard is augmented with a fourth row of keys and context-sensitive icons at the bottom of the screen. For example, digits, special characters and predictive text appear on the virtual keyboard.
The Passport's keys are also touch sensitive, and swiping them selects predictive text and deletes words. It also enables scrolling and cursor positioning. (Image courtesy of BlackBerry, www.blackberry.com)
