Google provided a solution for buffering issue when we watch videos on you tube. This is common problem when we have slow internet connection or internet disruption.This option available on the YouTube app in android device. If we already installed the app then we just need to update it. Let see how this app works.
The idea behind the offline videos is, we can save the preferred video for offline viewing and we can watch it later freely without internet.Video download is happens in the background when ever mobile is connected to internet and you will be notified once download is completed.
This option currently not available for all the videos.We can configure the video size to be downloaded ,smaller size will be downloaded quickly.
When phone is connected to internet we will be able to see all the categories in YouTube but if the internet is not available then we will see only offline categories.
