The KEYone is the first BlackBerry smartphone released by TCL after entering into a licensing agreement with the BlackBerry brand. Yes, it is an Android device again, and forgive me, BlackBerry 10 fans, but the company's own operating system was never popular enough to justify the development costs, and trying to combine Android with the ergonomics and security of BlackBerry is the only possible way to preserve the company's legacy. Although the KEYone was developed by BlackBerry itself, the new device illustrates how TCL plans to use its legacy. After the innovative, but out of line BlackBerry devices, the PRIV slider, and experiments with Android on TCL's rebranded devices - DTEK50 and DTEK60, we are again seeing a return to the classic QWERTY layout of devices in a new interpretation.
