The Galaxy S4 is Samsung’s flagship device launched earlier this year. The hardware specs weren’t all that impressive but Samsung introduced tons of new features in the software department. There was Air View (previously seen in Note 2), Air Gestures, Samsung Hub, Smart stay, Smart Pause, Smart Scroll, Group Play and much more. Another feature that attracted the attention of users was the lockscreen with beautiful effects such as Ripple effect, Ink effect, Lens Flare and more. This lockscreen can now be applied to any Android device running Android 4.0 and above using an app called Galaxy S4 Lockscreen.
