BlackBerry is gearing up to launch a new smartphone.

The company has started to tease its next handset, dubbed KEY2, which will sport a dual-camera system, LED flash and physical keyboard.

The smartphone is a follow-up to the KEYone, which launched at the Mobile World Congress consumer technology tradeshow back in February 2017.

Like the KEYone, the new phone will be powered by Google’s Android operating system.

BlackBerry typically adds its own software improvements to Android to improve security on the device – a key selling point for the privacy-focused company.

BlackBerry has shared a short teaser trailer for the new smartphone, which offers a brief glimpse at some of the new features.

BlackBerry has included a mysterious new button on the KEY2's physical keyboard.

The new key, which is labelled with a three-by-three grid of dots, did not featue on the BlackBerry KEYone.

Unfortunately, BlackBerry is staying tight-lipped about the purpose of this mysterious new button for now.

A spokesperson for the company told Cnet that the function of the new key would be revealed during the launch event next month.

BlackBerry has offered a brief glimpse at its new smartphone, which looks set to be the first from the company to offer a dual-camera system like the Apple iPhone X

It’s unclear whether the dual-cameras on the BlackBerry KEY2 will be used to take portrait-style photographs, like the iPhone X.

The iPhone uses information from both lens to separate the subject of the photo from the background, allowing it to artificially blur the latter.

The BlackBerry KEY2 will be unveiled in New York City on June 7 2018.

BlackBerry KEYone sported a single rear-facing camera, physical keyboard and was powered by Google's Android operating system. It cost £499 when it went on-sale in April 2017

BlackBerry revealed plans to launch ‘at least’ two new smartphones before the end of the year during a press conference back in January.

The KEY2 looks set to be the first of these new devices.

TCL, the multinational manufacturer which owns the right to sell smartphones under the BlackBerry brand name, shipped a mere 850,000 KEYone handsets in 2017.

But despite the poor sales numbers, company executives told The Verge they considered the KEYone an 'unqualified success'.

The BlackBerry KEYone cost £499 ($549) SIM-free when it launched two years ago.
