Questions tagged [android-4.2-jelly-bean]

Android 4.2 Jelly Bean (API Level 17) is the version of Android Operating System preceded by Android 4.1.

Google announced Android 4.1 (Jelly Bean) at the Google I/O conference on 27 June 2012. Based on Linux kernel 3.0.31, Jelly Bean was an incremental update with the primary aim of improving the functionality and performance of the user interface. The performance improvement involved "Project Butter", which uses touch anticipation, triple buffering, extended vsync timing and a fixed frame rate of 60 fps to create a fluid and "buttery-smooth" UI. Android 4.1 Jelly Bean was released to the Android Open Source Project on 9 July 2012, and the Nexus 7 tablet, the first device to run Jelly Bean, was released on 13 July 2012.

Google was expected to announce Jelly Bean 4.2 at an event in New York City on 29 October 2012, but the event was cancelled due to Hurricane Sandy. The new version was announced with a press release instead of rescheduling the live event, under the slogan "A new flavor of Jelly Bean". The first devices to run Android 4.2 were the LG's Nexus 4 and Samsung's Nexus 10, which were released on 13 November 2012.
