Simply Lockscreen - Android app on AppBrain I really like this new FREE screen locker replacement. There is no lag when unlocking anymore! You can also set your phone to vibrate directly from the lock screen now. Still could use some polish (larger clock?) but it hasn't been out that long. Hope the developer keeps working on it. Remember to disable the default screen locker or you'll have to unlock 2 every time. What do you guys think?
