BlackBerry 10 users are getting a new leak by way of OS 10.2.1.476 for the BlackBerry Z10, Z30, Q10, and Q5. However, sadly, users with a Z10 STL100-1 will not be able to use this OS.
Dark themes, locked Android runtime, and camera face focus are present in this build. However, there are a few issues with the OS such as your device PIN will remain on sides of screen, glitches with BBM, and a few bugs.
