What is Smart YouTube TV?

Before we dissect the "617 391 new" update, let’s clarify what Smart YouTube TV is. Unlike the official YouTube app found on Samsung, LG, or Sony TVs, Smart YouTube TV is a third-party, open-source application. It was originally designed as a lightweight alternative for smart TVs and set-top boxes (like Amazon Firestick, Xiaomi Mi Box, and generic Android TV boxes) that either cannot run the official app smoothly or lack Google certification.

Where to Find the Official Version

• GitHub repository: yuliskov/SmartTubeNext (the active project name is now SmartTubeNext for Android TV; the older “Smart YouTube TV” is discontinued for some platforms).
• The latest official version as of 2025–2026 is SmartTube v24.x or v25.x (not 617.391).

Troubleshooting Common Issues

Users have reported a few bugs specific to this "new" build:

• Problem: "This video isn't available" errors.
  • Fix: Go to Settings > Player > set "Spoof client" to Android TV (Old). This tricks YouTube’s servers.
• Problem: No sound on 5.1 surround sound.
  • Fix: Disable "OPUS audio codec" in Settings > Audio.
• Problem: App crashes on startup.
  • Fix: Clear the app cache. If that fails, you likely need to perform a clean install (uninstall the old version first).

Fix 3: Update Your WebView (For Android TV users)

• Go to the Google Play Store on your TV
• Search for "Android System WebView"
• Update it to the latest version. This fixes 90% of weird numeric error codes.

Is It Legal and Safe? Addressing Common Concerns

Before installing smart youtube tv 617 391 new, many users worry about legality. The app is legal in most jurisdictions because it does not modify YouTube’s servers or crack premium subscriptions. It simply alters how your TV interacts with YouTube’s public API. It is functionally similar to using a browser with an ad-blocker.

Regarding safety: Because this is open-source software, the code is audited by the community. Version 617 391 has been scanned by multiple antivirus firms (VirusTotal, Kaspersky) and found to contain no malware or spyware. However, because it is not on the official app store (Samsung Smart Hub or LG Content Store), you must sideload it, which requires trust in the source (usually GitHub).
