Have you ever used your phone as an emergency light source?
Did it went to sleep just when you almost found your keys in the drain?
Well, the lock-screen probably isn't bright enough for that.
Here comes "White Screen" app to the rescue!
It displays a completely white screen to maximize brightness and stays on until you dismiss it with a touch.
Use modern technology to find your way to the light switch in a dark room!
Okay, it started as a bit of a joke, but this app has already saved my toes from the sharp edge of my bed.
