BlackBerry 10.3 will be bringing a multitude of changes. One of these expected changes is a Dark Hub. This feature alone has been heavily requested from BlackBerry 10 users universally.
Aside from the additional Hub changes in 10.3, nothing more has been changed with a Dark Hub. With devices using an AMOLED screen, the Dark Hub will surely help retain battery life.
The BlackBerry Passport will be the first device to release with OS 10.3, with previous BlackBerry 10 smartphones receiving a 10.3.1 update later this fall. Check out the remaining photos, including the first look at Dark Hub on a Passport, courtesy our friend Dylan (aka @DHabkirk) :
