Watching matches on the big screen is the best experience. Fútbol Libre TV works on Android TV and Google TV sets, as well as the Amazon Fire TV Stick. Since the APK isn't in the TV store, you install it via "sideloading." Here are three methods.
Go to Settings → Device Preferences → Security & restrictions and turn on "Apps from unknown sources" for the app you'll use (Downloader or your file manager).
Install Send Files to TV on both your phone and TV (both on the same Wi-Fi network), send the APK, and open it on the TV to install.
Copy the APK to a USB drive from your PC, plug it into the TV, and use a file manager (such as X-plore) to open and install it.
On Fire TV, enable Settings → My Fire TV → Developer options → Install unknown apps and use Downloader just like on Android TV.
Browse the match list with the D-pad and press the center button to select. Inside the player you can switch servers if the stream drops.
