BlackBerry Z30 - its largest screen and most powerful phone ever

BlackBerry has unveiled its largest and most powerful smartphone yet, the Z30, as it looks to broaden its range of smartphones. The Z30 is the fourth BlackBerry 10 smartphone, featuring a five-inch Super AMOLED display screen and a new 1.7GHz quad-core graphics processor. The phone also features the largest battery capacity in a BlackBerry - 2880mAh - which will last for up to 25 hours, the company said.

The firm also announced BlackBerry 10.2, an update to its mobile operating system. Among the improvements from version 10.1 are changes to the BlackBerry Hub, including Priority Hub that learns over time and surfaces what it believes to be the most important information for you from email, social networks and other accounts. A new feature in BBM, BlackBerry Messenger in BlackBerry 10.2, is the ability to display popup previews of new messages with details of the message received on the lock screen of your phone.
