B TV 리모콘 is a free mobile application developed by EltaCrew for Android devices that support infrared sensors. It allows users to control their B TV using their smartphones. However, it is essential to verify if the smartphone is compatible with the app before downloading it.

The app is not supported on Samsung Galaxy S7 or any models higher than S6 as Samsung did not apply infrared sensors on these models. Users can check if their smartphone is compatible with the app by searching for their device model with the keywords "infrared" or "IR" on the internet or by pointing the top part of their smartphone to another camera while pressing the buttons on the B TV 리모콘 app. If a light appears, the smartphone is compatible with the app.
