Galaxy S I9000 users are unlikely to get the latest Jelly Bean update - Android 4.2 - through official channels from Samsung. However, with due credit to XDA Developers member - pawitp, the Galaxy S users can now relish the latest Jelly Bean features on their smartphone through the AOSP custom ROM.
The custom ROM based Android 4.2 update was earlier ported to the Galaxy S Advance, which brings a plethora of exciting features including multi-user support, gesture typing, new quick settings option, lock-screen widget, new camera app, photo sphere, enhanced Google Now, as well as new daydream feature and miracast display.
NOTE: As the ROM is an AOSP based custom release that is still under development, it may harbour a few untested bugs or broken features. So, users are advised to proceed with caution. It must, however, be noted that the ROM uses the same partition layout as the CM10 stable release.
