S2U2 (Slide2Unlock2) is a simple lock/unlock application which has the iPhone style slide unlocking. It can be used as a screensaver while you don’t use your device. And it’s has a CallerID function.

Although S2U2 is now called v1.16, it doesn’t mean it can be run perfectly on your device. Thanks to different devices produced by different vendors. So, please test it before use it everyday, especially the CallerID function.


– fixed the update problem of multiple appointments.
– removed “ReLockWaitMS” which caused some weird problems, i.e. no more relock.
– changed the default value of “NoKeyBoardHook” to 1; it’ll set to 1 as well when the “VolumeControl” is 0.
– fixed the S2U2 Settings that could not save/change the “Volume Control” & “Keyboard Hook” settings.
– some minor bugs fixed.

S2U2 v1.16 seems to have fully replaced v1.15 which has been released earlier, without closer details but the equal changelog.
