Invisible Lock is a cool Lock Screen app for your Android phone. The app can make your Lock Screen transparent, so your phone looks exactly as if it was unlocked, though it is actually locked.
As it is a transparent Lock Screen, you cannot use usual Pattern, PIN or Password to unlock device, instead the app provides a different technique to unlock the device. The phone can be unlocked by a gesture that you defined in the app’s settings. Invisible Lock provides four types of unlocking gestures – swipe from Top to Bottom, from Bottom to Up, from Right to Left and from Left to Right. However, you should disable the system lock screen by going to Settings > Security. Interested users can download Invisible Lock from XDA.
