Youtube is a great app. It has lot of good features.sports, action, drama, motivational etc. If you want any kind of video you will get it here very easily. The offline download option in it is very good.You can download the video when you are online and you can watch that video even when you are offline. This app works well on 4G network but also works very well without buffering on 3G network. My phone is 3G but still in my phone this app runs very well without any hassle.
If you are boring a lot so do not tension and download this app and enjoy the videos around the world and earn as well as a little bit of money.
