BlackBerry DTEK50 on AT&T network has started receiving a new software update. The update installs June security patch and is rolling out over the air as we speak.

The new firmware update arrives as build AAM312. In all probability, the update includes regular bug fixes and system improvements, other than the monthly security patch. Although a minor one, it is highly recommended as it optimizes the security of your Blackberry device.

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.
