If you want a Vanced alternative YouTube experience free from ads and featuring background playback as well as SponsorBlock, then YouTube ReVanced is your best option. The process of installation differs according to whether your device is rooted or non-rooted. Non-root users need to download the ReVanced Manager from the official GitHub repository and install it. Then, obtain a compatible YouTube APK (ideally a non-optimized one from APKMirror), then launch ReVanced Manager and click on the YouTube APK to patch. Select the features you want, apply the patch, and install the patched APK. To log in to YouTube, install microG before launching the app. Rooted users can patch the official app directly for seamless updates. ReVanced also has support for other applications such as Twitter and YouTube Music. Always download from reputable sites to prevent security threats.
