Important. The box must run Android TV or Google TV — it is the same system, only the interface differs. Tested on Android TV 14.
We can’t guarantee stable operation on modified Android without the TV interface and Google services: YaOS (Yandex TV), Salute TV (Sber), Fire OS (Amazon), HarmonyOS (Huawei), or cheap boxes with “plain” Android.
Samsung and LG TVs are not suitable at all: they run Tizen and webOS, and an Android app cannot be installed there.
