One of the easiest ways to customize your phone with out Rooting it other than adding a custom Launcher is to add a Custom Lockscreen. The market is flooded with lockscreens. There are lockscreens that make your phone feel like an iphone, lockscreens that add widgets, lockscreens that are themed, and the list goes on. Most custom lockscreens add a set of features that are not available with the stock experience. With all the features comes clutter, but not with MinimalLock Lite by app developer "RobJ". This lockscreen actually removes things from the lockscreen without removing any functionality and while retaining all the custom features.
MinimalLock is a gesture based lockscreen with notifications plus music control. It includes no buttons or sliders of any kind which frees up screen space for your favorite lockscreen wallpaper. Instead you use gestures. To access the music controls you simply double tap the lockscreen and go from there. A really neat feature that sets this lockscreen apart is the notification feature. It displays sms and missed call notifications as your contact pictures you can open the notifications with a tap or you can remove them with a swype. So Fresh and So Clean!
