About this app

This app lets you turn off either one of the screens on your Surface Duo while the device is in unfolded position, simply launch it from the screen you want to turn off.

Due to device limitations, navigation bar will be still visible while you are interacting with the other screen, but you can hide it touching the turned off screen (useful when you are watching a video on the other screen).

Also, there is a Quick Settings switch available for easy access from status bar. You have to add it manually editing your Quick Settings panel.
Once pressed, first empty screen will be turned off. If both screens are in use, left one will be turned off.

This app does not need any kind of permission to work properly.
Not tested to be compatible with Surface Duo 2.

Ratings and reviews

Much needed. Even when I fold the phone over it sometime still does two screens. This ensures it. However turning it off should be easier. Like a notification I turn off. It's free... No ads... Can't complain

I have been using the photos app and having a black picture to essentially replicate what this app does perfectly. I love the quick setting option too! Thanks!

It blacks out the second screen perfectly every time. I like it and use it a lot!
