BlackBerry Priv starts getting December security update, but only on AT&T
After Samsung announced that the Galaxy S7 edge devices are now eligible for the December security update, BlackBerry is following up with its own take on the security patch.
On top of that, only AT&T customers are seeing the update for the moment. If you meet both requirements then you should look for a software update with build number AAI020.
If everything goes well, we expect BlackBerry to start the global rollout of the December security update in the next couple of days. Obviously, the exact timing may vary by country and carrier.
It's unclear whether or not the update brings some other changes aside from the addition of the December security patch, but we will probably know more once AT&T or other carrier publishes the official changelog.
