Roku is an open-source software project that allows you to control your home theater with your Android device.

You can use the app as a remote for your Roku player or Roku TV, and you don't need to have any setup instructions or a manual to use it.

You only have to install the app, and it's done.

You can watch channels on your device or switch to other channels easily.

You can use the power button to turn off the TV or switch to another channel.

You can use the channel up and down buttons to change the current channel.

The app also has an up and down button on the menu screen.

This app is highly recommended when your normal smart TV remote has been broken or has run out of batteries, and you want to use the phone as a roku remote replacement.
