Google I/O will hold next month and Google is planning to release another version of Jellybean in the form of Android 4.3 in the place of Android 5.0 Key Lime Pie. Developers, users and journalists alike expect the next Android variant to be announced at Google I/O.
Android Police has found in its server logs that visitor connections from Nexus 4 and Nexus 7 devices running Android 4.3 with build number JWR23B. As you see the first character of the build is start with ‘J’ so this build is the new version of JellyBean not a Key Lime Pie update. Android police also digs around IP ranges and found to be associated with Google. One other source also supporting this point, The JWR23B build number was also spotted on Chromium project site pertaining to some errors, which also indicates that the build is real.
It do not matter what google calls the software update, but what changes are present. Hope all the bugs of Android 4.2.2 will be removed in this update. We are waiting for Google I/O.
