Youtube Premium APK (Youtube Mod) is a YouTube-made version of YouTube that comes with many additional features. Using the YT Mod APK is the same as the original youtube app. You will not face any problem while using it.
Have you ever used the youtube ad-free app, direct download guides, background video playback option, black mode, screen dimming option, Ads-Free ? I think no because these features are not on the youtube program but are available on the Youtube Mod APK. So without wasting time, you should download the Youtube App.
