The LG Optimus G has a very cool lockscreen with many beautiful unlocking effects like Particle, Crystal, DewDrop and Ripple effect. The most interesting ones are Particle and DewDrop effects.
When you swipe your finger over the screen to unlock your phone, it gradually shows a part of your homescreen until you completely unlock your Optimus G. The effect is smooth, simple and very practical. Now you can have this awesome lockscreen on your Galaxy S4 too!
