BlackBerry 10.2 is coming and promises to bring several new features and improvements to the platform along with its release. A newly released video now shows the update in action with features like toast notifications, marking contacts and groups as high priority and dark theme in settings. Level 1 notifications are accessible with a simple pinch gesture.However keep in mind that the update is still in an early stage of development and features like lock-screen previews are still not working.
You can still see some of what you can expect in the following video which demonstrates the latest (10.2.0.4xx) release of the BlackBerry 10.2 update.
