BlackBerry has started to roll out BlackBerry OS 10.3.1 for all of its BlackBerry 10 smartphones which brings them all up to date with the BlackBerry Classic when it comes to new features.

The headline feature of those is perhaps the addition of the Amazon Appstore which finally expands the amount of applications available on BlackBerry devices greatly, adding Android apps to the mix.

BlackBerry Blend syncs messaging and content across multiple devices, including computers and tablets; BlackBerry Assistant is the company's version of Siri or Cortana but accesses both personal and work content; and the BlackBerry Hub receives Instant Actions, a feature that enables users to organise and action emails, texts, BBM messages and more without having to access each individually.

Plenty of other functions and features are part of the update too, including the ability to adjust the power saving profile to increase battery life. And there are new camera options too, including an HDR mode.

BlackBerry 10 OS 10.3.1 is available for the BlackBerry Passport, Z30, Z3, Z10, Q10, Q5, and the Porsche Design handsets P’9983 and P’9982. The features are already present on the BlackBerry Classic.
