Android Jelly Bean

Android Jelly Bean (Android 4.1, 4.2, 4.3) is the codename given to the tenth version of the Android mobile operating system developed by Google, spanning three major point releases (versions 4.1 through 4.3.1). Among the devices that were launched with Android 4.1 to 4.3 already installed are the Nexus 7 (2012), Nexus 4, Nexus 10, Nexus 7 (2013), and Hyundai Play X.

The first of these three releases, 4.1, was unveiled at Google's I/O developer conference in May 2012. It focused on performance improvements designed to give the operating system a smoother and more responsive feel, as well as improvements to the notification system that allow for expandable notifications with action buttons, and other internal changes. Two more releases were made under the Jelly Bean name in October 2012 and July 2013, respectively, including 4.2—which included further optimizations, multi-user support for tablets, lock screen widgets, quick settings, and screensavers, and 4.3—which contained further improvements and updates to the underlying Android platform. The first device with Android Jelly Bean was the 2012 Nexus 7.

As of January 2025, 0.04% of Android devices run Jelly Bean.^[4] In July 2021, Google announced that Google Play Services would no longer support Jelly Bean after August of that year.^[3][5]
