Android 4.3 isn’t an overly dramatic advancement over Android 4.2, but the new version of Google’s mobile OS announced on Wednesday does bring a number of improvements that should appeal to both developers and end users. Highlights include the redesigned camera interface, general performance improvements for the OS including smoother animations, and long-awaited Bluetooth Low Energy support. MUTI-USER RESTRICTED PROFILES: This builds on the multi-user accounts on 4.2, but adds Restricted Profiles. These make it possible to do parental controls on the tablet, by changing the performance of apps and other services based on who’s logged in. It also blocks out access to stuff like in-app purchases. There’s much more to this than just parental controls, however, including options for provisioning in enterprise settings.
