For many years, the QNX-based BlackBerry 10 remained BlackBerry's bread-and-butter operating system. It's used on all new devices; older devices did not receive an upgrade to BB 10 (http://www.theinquirer.net/inquirer/news/2145581/rim-current-devices-won-t-upgraded-blackberry).
In January 2013, BlackBerry released a new, revamped version of the OS dubbed BlackBerry 10. Initially only available on a single touchscreen device, BlackBerry Z10, the new OS made it to subsequent devices including BlackBerry Q5, Q10, Q20 (Classic) and Q30 (Passport and Passport SE), touch-screen Z30 and Leap, as well as a counted number of Porsche design models.
BlackBerry 10 comes with the ability to run Android apps (installable via Amazon app store or Amazon Underground in latest releases); however, the OS lacks support for Google Mobile Services (GMS) and does not, in general, collect as much information about the user as Google-powered Android.
