Just in case you happen to be using the Sprint BlackBerry Q10 and the operating system update has yet to arrive, then you might want to check the settings and perform a manual update. I guess taking the Over The Air (OTA) route does not work out all the time.
With BlackBerry 10.2.1, one is able to download and run a fair number of Android apps. Not only that, it will also see the inclusion of Priority Hub that enables a quicker delivery of IMs, emails, notifications and calls. In addition, the inclusion of Wi-Fi Direct would deliver peer to peer sharing of content to other BlackBerry Q10 or BlackBerry Z30 models, making it far speedier compared to the plodding Bluetooth.
