For a while, if you wanted to save YouTube videos to your Android smartphone, you had to use third-party software that likely violated the YouTube terms of service. That's no longer the case, as YouTube now allows for videos to be saved locally, once you sign up for its $9.99 monthly service.
YouTube Red is the only method for saving YouTube locally that doesn't violate YouTube's Terms of Service.
You can unlock the ability to save YouTube videos to your phone for offline viewing by becoming a YouTube Red subscriber. This service includes many other perks, such as an ad-free YouTube experience, access to exclusive YouTube Originals videos and Google Play Music (the company's Spotify competitor).
Apps within the Google Play Store claim to let you download videos, but not only do they likely violate the YouTube Terms of Service, we cannot vouch for them. They may include malware or adware that slows down or ruins the Android experience.
Before you start, make sure your YouTube app is up to date by opening the Play Store app, tapping the Menu button, tapping My Apps & Games and selecting YouTube. Tap the Update button if it's there and tap Open if it's not.
After you subscribe to YouTube Red, here's how to download YouTube Videos to your Android Phone:
1. Tap the Save icon while watching a YouTube video in portrait orientation.
2. To find the videos you've saved for offline, tap the profile icon. It’s the one on the right that looks like a person.
3. Tap Offline videos.
4. Tap on a video to play it.
5. To remove videos, tap the Save icon again.
6. Tap Remove.
Now you know how to save YouTube videos to your phone!
