The Blackberry Z10 with model number STL 100-1 lacks some features from other Z10 models like White Balance and WiFi Direct despithe that STL 100-1 has the approprieate hardware to support these features . But Blackberry decided not to update some drivers with result not to give these features to these devices . Additionally the STL 100-1 with its WiFi Module supports Miracast connectivity only if Blackberry updates the driver for this module. But again Blackberry did not give these features to this model , disappointing its users .
