Although BlackBerry OS 10.3.3 was already known to be coming at some point, thanks to an early mention on the Inside BlackBerry Blogs, the rumors of the upcoming Android-powered BlackBerry Priv caused many to wonder if it would ever really see release. Addressing that concern, without actually saying he was addressing that concern, BlackBerry CEO John Chen laid out the plans for BlackBerry OS 10.3.3 to be launched in March 2016.
While the new device will provide a choice in OS to new and existing customers, the company remains committed to the BlackBerry 10 operating system, which enables industry-leading security and productivity benefits. Second, the company will continue to develop and enhance the BlackBerry 10 operating system and is confirming plans to release platform updates focused on security and privacy enhancements, with version 10.3.3 scheduled to be available in March 2016.
As we know it, there's already a few builds of 10.3.3 that have appeared in server logs and such but right now, there's no indication on any additional improvements that may be added to the OS outside of the mentioned security and privacy enhancements.
