While BlackBerry's smartphones are not as ubiquitous in the consumer market as they used to be, one can generally rely on the Canadian company to deliver when it comes to mobile security. The firm has a rich and exalted reputation in this field, which is why many businesses and governments still rely upon its expertise. Indeed, it came as little surprise that BB was the first to patch the QuadRooter vulnerability on both the Priv and DTEK50. Now the firm has begun to roll out the September Android update to these two handsets.
A recent Beta Zone update for the Priv brought the September Android security patches in early to several versions, although not the unlocked models sold for example on ShopBlackBerry.com and Amazon. With today being the official day for September's glut of Android security fixes, BlackBerry has been typically prompt in pushing the care package out to users.
Available to both the Priv and the DTEK50, the long and exhaustive list of bug fixes are outlined over at the Knowledge Base. Provided you own the unlocked variety of either device, you can avail the update by heading over to Settings app and navigating to About Phone --> System Updates.
If you're rocking one of the carrier versions, then you'll receive the update at their discretion. This is not particularly ideal, since you're essentially behind on critical security flaws, though it comes with the territory of being tethered to a carrier.
Anyway, if your device is of the unlocked kind, be sure to grab the update at your soonest convenience. Full details of all the fixes can be seen at the source.
