Update for Verizon branded BlackBerry Priv adds the latest Android security patch to the phone16
The Priv, which was released in November 2015, is no longer the latest 'Berry to come with a physical QWERTY keyboard. That honor goes to the BlackBerry KEYone which has been well received by the smartphone community. The keyboard on the Priv doesn't come close to the one on the KEYone as the latter has bigger keys and more features than the slide-out QWERTY employed by the Priv.
If you own a Verizon branded Priv and you see the notification that the update has arrived, before you continue with the updating process you should make sure that your phone is connected to a Wi-Fi network. If you can't find one, you should try to connect your Priv to a strong Verizon cellular signal. At the same time, you need to charge your battery up to 100% before downloading and installing the update on your BlackBerry Priv.
