The BlackBerry KEYone is a BlackBerry touchscreen-based smartphone with a physical QWERTY keyboard developed by TCL Corporation. Originally known by its unofficial code name "Mercury", the KEYone was officially announced at Mobile World Congress in Barcelona on February 25, 2017.
The KEYone is the fourth BlackBerry-branded smartphone that does not run the company's proprietary BlackBerry OS or BlackBerry 10 (BB10) platforms. It instead uses Android, customized with features inspired by those on BlackBerry phones, and security enhancements. The physical appearance of the KEYone is similar to the BlackBerry Classic and the unique BlackBerry Passport Silver Edition, both of which run on the BlackBerry 10 OS.
