The Android 4.1 Jelly Bean software has started rolling out and the unlocked Galaxy Nexus HSPA+ is the first to get the update, according to the Nexus blog post on Google +.

Galaxy Nexus HSPA+ users will be receiving update prompts in the next few days. All other models of the Galaxy Nexus, including Verizon and Sprint, are next in line to get Jelly Bean. Nexus S and the Motorola Xoom will also be upgraded.

There is no mention of the Samsung Galaxy S3 in the blog post, but a report published in the Christian Post claims the device will get Android 4.1 in the fourth quarter of 2012. Samsung is yet to officially announce if the Samsung Galaxy S2 and S3 will recieved the upgrade.

Samsung told Tech Radar that the upgrade is dependent on, the system requirements, the structural limitations, and the level of cooperation from the component suppliers and the software licensors. If Samsung decides to make the update available to the users it will be released upon successful completion of development, the giant told Tech Radar in a statement.

It's difficult to get as excited about Android software updates as those of Apple's iOS, because manufacturers and carriers aren't clearing the new versions quick enough, and therefore many people are left with older versions of the software on their devices.

The Android 4.1 Jelly Bean update comes with a whole host of features that will enhance Android devices. Its performance is significantly faster than Ice Cream Sandwich. Jelly Bean is built to harness the power of mobile processors better, and improve CPU utilization, according to Google.

Project Butter

The main aim of Jelly Bean's Project Butter is for devices to run with silky smooth graphics and a seamless response rate. It does this by predicting where the user's finger will be.

Google Chrome Default Browser

Honeycomb and ICS's default browsers have been replaced by Google Chrome on Jelly Bean. It's speedy, elegant and one of the best browsers on the market.

Google Now

This is a new feature to Jelly Bean that is run through a Siri-like voice recognition tool. It gives you answers and prompts based on your interests identified through your Google Search history, calendar and location data.


On Jelly Bean, widgets can be re-sized and organized by users manually.

Improved Camera App

The Jelly Bean camera app has been improved the way photos can be viewed. Users can access their photos in an instant with a swipe gesture and a pinch-in-zoom gesture turns the screen into a filmstrip.

Android Beam

The NFC file- sharing interface has been significantly improved through Jelly Bean. Users can now hook-up to another NFC - enabled Android phone by tapping it against another device. Information is then transferred between the two phones through Bluetooth.

Nexus 7

Google finally unveiled its own Android tablet, the Nexus 7, in collaboration with Asus, at its annual developer's conference in June.

The 7-inch Android 4.1 Jelly Bean Nexus tablet is as light as a paperback book at just 340 grams and is extremely portable. Yet, its small frame is packed with a host of features.

By tapping into Google's Play store, the tablet becomes the ideal device for gaming, movies, apps, e-book and magazines.

As expected, the Nexus 7 came with a 1280 x 800 display and a Tegra 3 chipset. Its quadcore CPU, 12-core GPU makes navigation and gaming extremely smooth.

In addition to its front-facing camera, WiFi, Bluetooth, GPS, gyroscope and accelerometer, it also has up to nine hours of video playback.
