A new firmware for the Galaxy S III has been leaked. It’s a test firmware of the Android 4.2.2 (I9300XXUFME3) for the previous Galaxy S flagship and going by the feature set, Samsung is looking to add many features you’d find on the Galaxy S4. The Galaxy S III firmware boasts a Galaxy S4-like lock screen, Adapt Display and Professional Photo display modes, two-finger swipe toggles, improved S Voice, Smart Switch widget and lots more.
Do note that this firmware is not the final version but the rumoured rollout is expected to begin from June.
