With immersive full-screen mode introduced in KitKat. Application can be shown full screen while hiding both top and bottom bars. Now you can test your screen for dead pixel any where!

This app turns whole screen into 4 colors (5 if you count black too), starts with black then red, green, blue, and white. Next color will be shown by clicking anywhere on screen. To exit this app, just made a gesture from outside of the screen to inside, now top and bottom bars will appear again.
