Samsung did confirm after Galaxy S4 launch that many of the software features of its new flagship will be available via update for the Galaxy S3 as well. There’s now an apparently leaked Android 4.2.2 build for Galaxy S3 in the wild, which not only brings Android 4.2 Jelly Bean upgrades, but a host of new features that are currently exclusive to Samsung’s latest Android flagship smartphone. Fair warning though, this leaked build isn’t official, so you must assume all the risks of flashing an unverified and unofficial ROM before proceeding.
This Android 4.2.2 Galaxy S3 build brings a new UI for Settings app, updated version of S Voice, Smart Watch widget, driving mode, Voice Control, Daydream and a host of software and visual tweaks. There’s a caveat though, this leaked build isn’t compatible with U.S. variants of the Galaxy S3. It is only compatible with i9300 model, also known as the international variant of Galaxy S3. If you happen to have that one lying around, it is all up to you if you’re willing to try out this leaked Android 4.2.2 build on your device.
