BlackBerry DTEK70 to be unveiled on 25 February

BlackBerry's latest Android phone will be shown off just days before Mobile World Congress opens

The last in a trio of BlackBerry Android devices, the DTEK70, will be unveiled on 25 February. Codenamed Mercury, the device will be shown off for the first time just days before Mobile World Congress 2017 kicks off.

It follows on from the lacklustre BlackBerry DTEK50 and the much better BlackBerry DTEK60.

It's not yet known how much the BlackBerry DTEK70 will cost. However, the rumoured specifications suggest it'll be closer to the £275 DTEK50 than the more expensive £475 BlackBerry DTEK60.

If blurry images courtesy of BlackBerryCentral are anything to go by, the BlackBerry DTEK60 will follow the BlackBerry Priv by incorporating the company's iconic Qwerty keyboard. This has since been confirmed in clearer images which were spotted on Chinese website Weibo.

Beyond the physical keys, a recent sighting on Geekbench suggests that the forthcoming BlackBerry might shy away from the top-end specs seen in the DTEK60.

Instead of continuing the trail towards the upper Android echelons, the keyboard-toting handset could use a Snapdragon 625 processor (running at 2.02GHz).

Geekbench also revealed that the handset could come with 3GB of RAM, 32GB of storage, a 4.5in HD display, an 18MP rear camera, an 8MP selfie cam and a 3,400mAh battery. If this is the case, the new phone will need to offer something more, and a keyboard would fit the bill very nicely indeed.

These specs also back up comments made by BlackBerry CEO John Chen when he bemoaned the Priv for being too expensive: "A lot of enterprise customers have said to us: 'I want to buy your phone but $700 is a little too steep for me. I'm more interested in a $400 device."

Although the DTEK60 is a competent device, reviews criticised the tricky placement of the fingerprint sensor. The leaked images seen of the BlackBerry Mercury so far - which may or may not be accurate - indicates that it will integrate the fingerprint sensor into the keyboard's space bar, thus moving it from the chassis.
