Remote for Android TVs and Devices: CodeMatics is a remote control application for your Android devices. It works over the WiFi network and requires a compatible Android TV or device to be connected to the same WiFi network. 

The application is very easy to use. The first thing you have to do is to make sure that your Android TV or device is connected to the same WiFi network as your mobile device. You can check this by going to your phone settings and looking for the WiFi network name. Next, you have to open the application and select the TV or device you want to control. You will be able to see all the settings in the application, such as power, mute, channel list, playback and more.
