This app is designed for Devant TV control using your phone. This was not the official Devant TV app, but with this Remote Control app, you are able to control it. Our app has many remote models, so you can pick out the one that's perfect for your device. The app was developed to help you use your Devant TV device even if you cannot find the manual remote control! However, please take note that the app requires an IR sensor on your phone.
