BlackBerry KEYone for AT&T gets new update that includes the October Android Security Patch
According to the AT&T website, the carrier has pushed out a software update for the carrier's version of the BlackBerry KEYone. The update carries a build number of AAP606 and weighs in at 40-46MB. Once installed, the update features the October Android Security patch, including a fix for the BlueBorne vulnerability. The version of Android that will be running the handset remains at Android 7.1.1.
Once you receive the notification that the update has arrived on your device, before you continue the updating process, you should make sure that you are hooked up to a Wi-Fi network. Otherwise, the update will not load on the handset. At the same time, check to be sure that the battery is completely full. Your KEYone must be currently on software build AAN596 or AA0750 in order to install the update. If one of those two builds is not currently running your phone, you will need to install either one on your unit first before loading the new software on your KEYone.
Since the update is being disseminated OTA, it might not reach your phone for a few days yet. If you're impatient, you can try to manually update your AT&T branded KEYone by going to Settings > AT&T Software updates > Check for updates.
