T-Mobile rolls out January security patch to the BlackBerry Priv
However, the update was only deployed to those Android smartphones bought through BlackBerry's online store, which means carrier-bounded devices were not eligible for the security patch.
The Uncarrier is now seeding Android 6.0.1 Marshmallow build number AAI459 to all Priv units purchased through its online, as well as brick and mortar stores.
Although T-Mobile has already updated BlackBerry Priv's support page to reflect the new change, aside from the fixes included in the patch, there aren't any other features or improvements mentioned in the changelog.
On a side note, we expect the next security update for the BlackBerry Priv to be rolled out by T-Mobile sometime in mid-February, seeing that the carrier released December and January patches on December 13 and January 17, respectively.
