As is the case with OTA updates, it may take a while to hit your device. If you do not want to wait, head to Settings > About device > System updates to check for it manually. Before hitting the download button, ensure that your device is at least 50 percent charged and connected to a WiFi network to avoid extra data charges.
This mid-range device from BlackBerry was launched last year in August minus the legacy qwerty keypad. It runs Android Marshmallow on board.
