Samsung Galaxy S4 owners might be excited by the above video. It's a very stable version of Samsung’s Android 5.0 Lollipop, running on the Galaxy S4! It seems obvious that Samsung is much farther along in the development stages of Android 5.0 for older devices than we might suspect this early in the game. Of course, we also see TouchWiz running alongside Android 5.0, but for those who don't mind Sammy's UI overlay, that's not a bad thing. Regardless, even the Android purists should be impressed that Samsung is this far along in the process. It's possible that several of Samsung's current devices could be Android 5.0 ready by the end of the year!
