When Jelly Bean 4.2 was introduced, many new features were seen like gesture typing, expandable notifications, a new look Google Search as well as a new lock-screen. The lock-screen has undergone many changes with the change in the Android OS. The Jelly Bean lock-screen has a ring in the center with different options available while swiping in different directions. This idea was favored by many users but it was only available on the Jelly Bean OS. Not anymore !
Android users who are on Ice Cream Sandwich (4.0) and below can get a Jelly Bean style lock-screen. For this purpose an app named Holo Locker must be used. Holo Locker is a simple and fast lock-screen replacement, based on stock Jelly Bean lock-screen.
