Follow these steps to verify if your TV runs original Google TV OS.
Power on your TV or Google TV streaming device.
Open the Settings menu from the top-right corner of the Google TV home screen.
Select "System" or "Device Preferences" from the settings menu.
Open "About" and look for Android TV OS or Google TV information.
Make sure Google Play Store is available. Masjidi TV app installation requires Google TV or Android TV with Google Play.
Note: Some smart TVs use custom operating systems and cannot install Google Play apps directly. In that case, use a Google TV streaming box.
