We speculated it to arrive sometime in June and the indications that we got today are more than enough to fill us with joy and excitement. You must not have forgot that the first leaked Android 4.2 Jelly Bean firmware came out in the last week of February and now we have another leaked firmware that assures the Galaxy S3 users around the globe that the official release of the Android 4.2.2 Jelly Bean update for the device is just at hand.

The latest leak is actually an unofficial release that is still being tested for bugs and performance. I have been testing it on my S3 for a few hours and believe me it is pretty stable ad far more better that the earlier leak. That is not to say, the firmware is bugless but they are minor. The new leaked I9300XXUFME3 firmware, apart from bumping your phone’s OS version to 4.2.2, also comes with some pretty new features and enhancements directly from recently released Galaxy S4.

Having installed the new Android 4.2.2 leaked firmware on your Galaxy S3, you’ll feel more like owning a Galaxy S4. And if you are thinking of upgrading to S4, think again, as most of S4 features and apps have already made their way to Samsung’s old best-seller. Here is a short list of some of the new features and changes brought by the new firmware:

  • OS version bumps to the latest Android 4.2.2 Jelly Bean
  • New Lockscreen with several pages that can be personalized with multiple widgets and shortcuts. Improved ripple effect and light effect from the Galaxy S4. Now you can also set a personal message at the LS.
  • Now, there are two pages at the Notification panel with more shortcuts.
  • Android 4.2.2 Daydream feature.
  • Galaxy S4 like tabbed Settings interface.
  • Galaxy S4 S-Voice app
  • New Driving Mode (voice assistance feature)
  • Most apps now run full screen without showing the status bar (S4 feature)
  • A few new widgets (do not expect S4 AccuWeather widget)
  • Various new options under device Settings
  • Many others…
