Google has disabled the SmartTube app on various Android TV devices, including NVIDIA Shield TV, Walmart Onn boxes, and certain Sony and TCL TVs, due to it being flagged by Google Play Protect. The app's developer, yuliskov, confirmed that the app's digital signature was compromised, prompting plans to transition to a new digital signature and app identifier. Users do not need to uninstall the existing version, but the new version will be released as a separate app requiring reconfiguration. Some users have suggested disabling Google Play Protect to regain access, but it is recommended to keep it enabled for security. The SmartTube app offers features like SponsorBlock support, live chat, picture-in-picture mode, and customizable video quality settings.
