Android 4.3: Jelly Bean Improvements 
After a long wait, Google finally released Android 4.3 yesterday. It's a minor 
update that has more new APIs and improvements for the existing features than 
exciting new features.

The third and final Jelly Bean installment brings support for virtual surround 
sound, OpenGL ES 3.0, wireless display, Bluetooth 4.0 (Bluetooth Low-Energy), 
Bluetooth AVRCP 1.3 (displays song metadata), restricted profiles, WiFi 
location detection even when WiFi is disabled. There's also a new tab for 
disabled apps in the settings and the phone app suggests numbers and names when 
you enable "Dial pad autocomplete".

"Restricted profiles enable parental controls, so certain family members are 
prevented from accessing mature content. Likewise, retail stores can use 
tablets to show off product information, and shops can use tablets as point of 
sale systems," explains Google. Restricted profiles let you limit access to 
apps and content.

Many Android devices already support Bluetooth 4.0, but now there's native 
Android support. Bluetooth 4.0 is great for low-power devices. "Android-powered 
Bluetooth Smart Ready devices running the latest OS will be compatible with 
virtually any Bluetooth enabled product — from the keyboards or headphones they 
already own, to the latest generation of power-efficient Bluetooth Smart 
appcessories (accessories + companion apps) like Fitbit or the Pebble watch," 
informs Bluetooth.com. More smart accessories will be able to connect to 
Android devices, Google Glass will have a better battery life when it will be 
released, smart watches will have to be recharged less often and there's a long 
list of medical and fitness devices that become smarter: thermometers, heart 
rate monitors, blood pressure monitors, pedometers, weight scales and more.

OpenGL ES 3.0 is the latest version of the popular 3D graphics API that 
enhances the rendering pipeline to accelerate more advanced visual effects, has 
better support for textures and texture compression. The specs were published 
last year and Qualcomm's latest Adreno GPUs already support it. You can find 
them in devices like HTC One, Galaxy S4, Nexus 4 and the latest Nexus 7. ARM's 
Mali T604 also supports it and you can find it in Nexus 10. The native OpenGL 
ES 3.0 will mean that you'll be able to play the latest games and see all the 

The first device that ships with Android 4.3 is the new Nexus 7. All the Nexus 
devices that were updated to Android 4.2 will be updated to Android 4.3: Galaxy 
Nexus, Nexus 4, the original Nexus 7 and Nexus 10. You'll probably wait for the 
OTA updates, but Google also provides the firmware here. Galaxy Nexus is the 
first Nexus device that gets 3 significant Android updates. 
When your work speaks for itself, don't interrupt.
