BlackBerry pushes out June security update for Android phones purchased from the manufacturer
The phones receiving the update include the BlackBerry Priv, BlackBerry DTEK50, BlackBerry DTEK60 and the recently released BlackBerry KEYone. After the update is installed on your phone, the security patch level will read June 5th, 2017. You can double check to make sure that the new security patch has been loaded onto your 'Berry by going to Settings> About Phone.
This should be treated like any other OTA update, meaning that once you receive notification that it has arrived on your 'Berry, you need to make sure that your device is connected to a Wi-Fi signal. At the same time, your battery should be charged to 100%
Receiving timely security updates is a good reason why you might want to consider buying your next BlackBerry directly from the company. You can check out the Shop BlackBerry website by clicking on this link.
