Specifications that were published on the Blackberry website suggest that the smartphone maker's latest model will include a fingerprint sensor.A page on the upcoming BlackBerry DTEK60 that was subsequently pulled offline detailed a reversible USB-C connection, a 21MP rear camera, a fingerprint sensor and a customisable “convenience key”.It would also have a 2560 x 1440 QHD resolution, powered by a Qualcomm Snapdragon 820 64-bit processor and 4GB of RAM.A step up from the “world's most secure smartphone” in the DTEK50, the DTEK60 ups the screen size, throws in a heap more power and improves security even more with BlackBerry's first fingerprint sensor on a smartphone.
