In Short

Version 7 of the BlackBerry operating system introduced a handful of iterative upgrades, including managing which icon panels were present and a new Liquid Graphics rendering engine which significantly improved browser performance. Thanks to new magnetic compass hardware, and a new graphical overlay framework, BlackBerry 7 also introduced support for augmented reality apps. Other hardware features, such as NFC, were also accommodated in the new software. We also started seeing voice-activated universal search in BlackBerry 7. A later update, BlackBerry 7.1, included mobile hotspot functionality and a device analyzer to diagnose problems. BlackBerry 7 was originally to be branded as version 6.1, though that changed before it went live through the launch of the BlackBerry Bold 9900.
