It wasn't all that long ago when we heard the Android 4.2.2 update for the Galaxy S III had been delayed and while that hasn't changed, there has been a leak. Android 4.2.2 Jelly Bean (I9300XXUFME7) has leaked for the Galaxy S III. But with that, there is one warning you will likely want to know up front -- this is still considered to be in the testing stages.
Samsung is expected to have this ready and available for the Galaxy S III in July or August and while we would not suggest running this (at least on a primary handset), this leak does provide us with details. For example, this build has arrived with an ID of JDQ39 and a handful of features from the GALAXY S 4 including the most up to date version of S Voice.
Some of the other GALAXY S 4 specifics include the Adapt Display and Professional Photo screen modes, the updated Settings UI and the addition of Voice controls. That last one will let the user control the phone using nothing more than their voice. The S4 features also include an update to the lockscreen. This means multiple widgets along with the Ripple and Light unlock effects and the option to set a personal message and adjust the clock size.
Aside from the GALAXY S 4 features, this update also includes Daydream and the Driving mode, some new additions in the notification center, the ability to run Samsung apps in a full-screen mode, a smart switch widget and the option to have a white background in the gallery.
With that, while we have already made it clear this is a test build -- there is the possibility of running this release. That being the case, you will need to download and install the firmware and know going in that this process will erase all the data you currently have on your device to include that found on the memory card.
