Google officially announced (http://www.gsmarena.com/android_43_unveiled_with_improvements_all_around-news-6455.php) the latest version of Android operating system, 4.3, at its event today. The newest version of Android is a minor upgrade over the currently present Android 4.2 Jelly Bean OS and brings restricted profiles, a few other minor features along with a bunch of performance enhancements.

As one can expect, the Android 4.3 Jelly Bean OS will be first available on Samsung Galaxy Nexus (http://www.gsmarena.com/samsung_galaxy_nexus_i9250-4219.php), Nexus 4 (http://www.gsmarena.com/lg_nexus_4_e960-5048.php), Nexus 7 (http://www.gsmarena.com/asus_google_nexus_7-4850.php) and Nexus 10 (http://www.gsmarena.com/samsung_google_nexus_10_p8110-5084.php). What might come as a slightly surprise is that you won't even have to wait a day - the update will start rolling today. After the roll-out to the Nexus line-up, the latest Android release will be seeded to the Google Play Editions of Samsung Galaxy S4 (http://www.gsmarena.com/samsung_i9500_galaxy_s4-5125.php) and HTC One (http://www.gsmarena.com/htc_one-5313.php). We got no time frame for that, but we were promised it will be happening soon.
The Android 4.3 Jelly Bean software update will be available over-the-air (OTA) so keep an eye for that notification.
