As we know that Youtube is freely available in phone and now you can download that helps you to watch in offline. But you can't see on sdcard when you want to see you always need to open Youtube. In this blog I'll help you to download and free to share to anyone. Please follow below steps - - -
1) First open your fevorite browser and type youtube.com on address bar
2) Select any video that you want to download - then do some changes on link at address bar
3) For example this is website "https: //m.youtube.com/watch? v= 9TgEpIZNiXs" - you just need to add "ss" without quote before youtube like - "https: //ssyoutube.com/watch? v= 9TgEpIZNiXs" - then just press enter
4) You will redirect to another website - just select resolution - click on Download button. That's it
