Best one I've seen I really like this lock screen. It's the only one that I've seen that I actually want to use. The only problem I have with it is that it doesn't disable the home key before you unlock your device. After I hit my home key and I lock and unlock my device again  the lock screen doesn't appear for a moment. Allowing me to access my home screen and/or any app that I already had open. I don't know if this problem is able to be fixed without root  but if it is then I'd like to see this fixed in a future update.
