Invisible lock ---------------------
This is an invisible lock where in it will block access to the screen but will show the screen behind this lock. We can see everything on screen clearly but we cannot access anything until the pre-configured swipe gesture is drawn. We can select any swipe gesture from available gestures from the app settings page. Currently this app supports 4 gestures to unlock as explained below:
- Swipe Right : Swipe from left side to right side horizontally with any finger on lock screen
- Swipe Left : Swipe from right side to left side horizontally with any finger on lock screen
- Swipe Up : Swipe from down side to up side vertically with any finger on lock screen
- Swipe Down : Swipe from up side to down side vertically with any finger on lock screen

By default, this app will lock the screen 5 seconds after the screen turns off. This can be configured from the app settings page.
This app will automatically unlock while incoming call.
Note:
1) Please disable default system lock or any other lock app in order for this Invisible Lock to function properly.
2) Though this app blocks access to the screen, we can still access Notification Bar and hardware buttons (if any) on the device. I am working on this to block them and will try to include in the next version.
