Android 4.3 features new restricted profiles for kids, OpenGL|ES 3.0 for game developers, a redesigned camera interface, Bluetooth Low Energy support and general performance improvements. Android 4.3 will still be called ‘Jelly Bean’. Darrell wrote a post detailing every new feature in Android 4.3.
Recently, Google started selling the Samsung Galaxy S4 and the HTC One with a pure Android OS. As Google can update those devices pretty easily, the company mentioned that the Galaxy S4 and HTC One will receive the 4.3 update “very soon” as well.
Google didn’t announce any release date of Android 4.3 for third-party device makers. OEMs may have to test their UI layers first (like Sense or TouchWiz) before rolling it out to their users.
