BlackBerry Passport Black Edition :
The Passport comes with a 4.5-inch square touch display with a 1440 x 1440 resolution and 453 PPI pixel density. Thanks to the integration of a touch-sensitive panel inside the hardware QWERTY keyboard below the display, your fingers almost never get in the way of reading or otherwise interacting with on-screen content. The Passport’s hardware brawn is supplied by a 2.2GHz Snapdragon 801 quad-core processor and a spacey 3GB of RAM along with 32GB of expandable internal storage. Running BB OS 10.3, the productive smartphone is powered by a huge 3540 mAh battery, which lasts 30 hours. Although the device ships with a 13MP camera with optical image stabilization, and a powerful processor, 4K video recording isn’t being advertised anywhere, but it is said that the feature will come in an update.
