Samsung Galaxy S3 I9300 updated to official Android 4.2.2 Jelly Bean XXUFME3 leaked firmware

Android 4.2.2 Jelly Bean firmware is now available for the Samsung Galaxy S3 as the files have been leaked on earlier. It is an official build, but it might not be the final version. Leaked firmware files are usually uploaded to non-official channels of Samsung and, from time to time, these will see the light of day allowing Galaxy S3 owners to keep up with the latest Jelly Bean features before an official channel will be opened.

This is an Android 4.2.2 updating firmware that is available only with the International variant of the Samsung Galaxy S4. There is no confirmation telling us that this I9300XXUFME3 firmware is the same as the one on the Samsung Galaxy S4. The official release of an Android 4.2.2 Jelly Bean is expected to be available starting with June for the Galaxy S3. The current leaked XXUFME2 Jelly Bean ROM is currently in testing phase at Samsung’s dev center.

Here’s some of the improvements added with this Android 4.2.2 JB for your Galaxy S3 phone: Build JDQ39 version, new S4 lockscreen with multiple features, New screen modes, daydream, Driving Mode, expanded notifications, new Notification Center  toggles, revamped Settings UI with tabbed S4 interface, Galaxy S4 voice controls, Samsung apps with full screen support, brand new S-Voice from SGS4, new smart switch widgets and tons of other new functions.

Galaxy S4 Lockscreen with this build of I9300XXUFME3 firmware brings new actionable lockscreen widgets, unlock effects such as Ripple and Light. Improved ripple effect which looks better than it did before with Android 4.1.2 JB. Now you can change clock size and enter a personal message.
