BE CAREFUL/SERIOUS WARNING I installed this crap on my Samsung Galaxy S, running Cyanogenmod 10.1 and it blocked my whole phone. The password screen does not let you type any password and it was difficult to enable the keyboard, and after typing nothing happened or was saved and the phone remained blocked. I had to reinstall a back up of the full system.
Gary I purchased this with the hope of preventing the unintentional screen unlocking from the stock android slider. This works fine except that the screen does not time out like the android slider instead stays on the time set for apps and the timer resets with esvh of the fake security keypad is pressed. This needs to be fixed to prevent battery drain.
