Some users do not like the stock lock screen on their Android phones. It’s simply a matter of taste, style, and whether or not you enjoy rings or puzzles. Thankfully, those discontent with their lock screens have a variety of replacement options, some of which require root and some that don’t.
XDA Senior Member rori~ has developed a non-root lock screen replacement called CyanX Lock. Currently, the app is in beta testing and, as the developer says:
deliberate expiring date, because I´m fully aware of problems and don’t want this early version to have a long lasting presence on the net.
Don’t be surprised if the app suddenly stops working for you–it was intentional. The application also has quite a few fun features, including:
standalone lock widget, unlock options, gestures, sense, sensor, custom backgrounds, colors, size, sounds,…
So pretty much everything you’d want in a lock screen plus a little extra, which is never a bad thing. The app is being consistently updated as well, so it won’t be long before those pesky bugs are gone and it is officially released.
If you’d like to replace your lock screen, you can find screen shots, details, and a full change log in the original thread._________
