One of the star features of Android TV is Chromecast-Built in, an application that replicates (almost completely) the behavior of Chromecast devices. Nevertheless, It may not come fully active when we configure our Android TV for the first time, preventing our mobile from recognizing it at all times.
We are going to teach you how to make Chromecast Built-In be always active and recognizable from the mobile phone, even if we are not playing content. So we can send Netflix or Disney + so that the Chromecast is already prepared and you just have to press play.
