Question about Samsung UE50RU7170

Samsung has its own operating system called TizenOS. You will find the Google Play Store here in vain, as the OS has little to do with the conventional Android that you find on familiar devices. TizenOS has its own app store, similar to LG & Co, which do not use Android OS.

However, you are guaranteed to find Teleboy apps among them, as the most common apps are preinstalled or in the App Store.
I use TizenOS myself on a 2015 model and you can find the app there relatively quickly.

The TV is a SmartTV with TizenOS. If Teleboy is available on the GooglePlayStore, then yes.
