Jelly Bean(OS) + Bluetooth Smart

Android "Jelly Bean" is the name given to three major point releases of the Android mobile operating system developed by Google, having versions between 4.1 and 4.3.1.

Faster, Smoother, More Responsive

Enhanced Bluetooth Connectivity

Now we can design and build apps that interact with the latest generation of small, low-power devices and sensors that use Bluetooth Smart technology

Bluetooth Smart is not backward-compatible with the previous, often called Classic, Bluetooth protocol. The Bluetooth 4.0 specification permits devices to implement either or both of the LE(low energy) and Classic systems. Afterwards more advance form is developed called as Bluetooth Smart Ready.

The example is not associated with android but for convenience look at it.

So, for example, the iPhone 4S, a Bluetooth Smart Ready smartphone, can connect to the Bluetooth Smart heart rate monitor with Bluetooth 4.0, but it will also work with classic Bluetooth devices, such as hands-free kits or your car's stereo.

Bluetooth Smart minimizes power use while measuring and transmitting data for fitness sensors like Fitbit, Runtastic and other devices, making your phone or tablet more power efficient.

Android Jelly Bean gives you a single, standard API (application program interface ) for interacting with Bluetooth Smart devices.

Dial pad autocomplete

Just start touching numbers or letters and the dial pad will automatically suggest numbers or names.

Audio

Virtual surround sound , enjoy movies from Google Play with surround sound on Nexus 7 (2013 edition) and other Nexus devices.

Graphics

OpenGL ES 3.0 ( computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics such as those used by video games, typically hardware-accelerated using a graphics processing unit GPU ) - Android now supports the latest version of the industry standard for high performance graphics.

Wireless Display for Nexus 7 (2013 edition) and Nexus 10 - project from your tablet to a TV.

Input

Easier text input is settled by an improved algorithm for tap-typing recognition makes text input easier.

Lower latency input for game-pad buttons and joysticks

Locations

Location detection through Wi-Fi , use Wi-Fi to detect location without turning on Wi-Fi all the time.

Networking

Bluetooth Smart support (a.k.a. Bluetooth Low-Energy) , devices like Nexus 4 and Nexus 7 (2013 edition) are now Bluetooth Smart Ready.

Bluetooth AVRCP 1.3 support , display song names on a car stereo.

-The basic features of this operating systems are power efficient , improved privacy content ,Fast processing and improved GUI. Rest features are of previous androids .
