Black Screen Mirror

For smartphones and tablets, turning off the power and making the screen black makes it possible to use it as a mirror.

However, turning off the power once, when turning back on, turning on the power, putting a passcode, etc. is troublesome.

So, when you launch the application, it is a convenient application that simply makes the screen black and can be used as a mirror.

It is embarrassing to use a mirror application that reflects yourself on the screen with a camera, such as when there are many people nearby such as in a train. Please utilize by all means at such time.

Once, touching the screen also added a function to change the color of the screen.
