Smart YouTube TV is an open-source wrapper application designed to provide a native TV interface for YouTube videos. Unlike the official app, which often forces updates and drops support for older Android TV boxes, version 6.17.740 provides a standalone, lightweight alternative. The 6.17.740 build specifically targets stability improvements and interface synchronization with the then-current YouTube web standards.
The developer implemented an internal update checker. Version 6.17.740 stabilized the update notification system, allowing users to choose between four different launchers (1080p Main, 4K Main, 1080p Alt, etc.) without reinstalling the core APK.
Smart YouTube TV APK 6.17.740 is a third-party Android TV client built to provide a more TV-friendly YouTube experience on devices where the official YouTube app is unavailable, limited, or behind device certification restrictions. It replicates the familiar Leanback interface, adds configurable playback and account options, and often works on set-top boxes, custom ROMs, Fire TV devices, and older Android TV builds.
Because it is open-source (code available for anyone to audit) and widely used by millions, yes. Just ensure you download it from the official repository (GitHub: yuliskov/SmartTubeNext) and not a random APK mirror.
