When will my device get the Android 4.3 update (Jelly Bean)? Android 4.3 (Jelly Bean) was officially announced on July 24, 2013.

(You can review the high level changes in Jelly Bean at the official Android Developer's site or the announcement on the official Android blog.)

Of course, not all devices will get this update right away and others won't get it at all. Each manufacturer and carrier often choose to add their custom modifications which tend to delay the official release.

When will each device get Android 4.3, either officially or unofficially, if ever?
