Google announced that YouTube would be getting an offline playback mode in India during the launch of the Android One initiative in the country earlier this year, and the feature is now rolling out to users. The ability to save videos for offline viewing is not limited to Android One handsets, and is available to all users in the country.
The YouTube app now shows a download icon next to the like buttons, which allows users to download the videos. There's even an option for selecting the resolution of the video to be downloaded.
Not all content is downloadable due to existing copyright laws in the country. For instance, music videos from record labels are not available for offline viewing. The content that is available for download is viewable only within the app in a special tab called Offline.
The update is rolling out in stages to users in India, so if you don't see it yet, we suggest trying again in a short while.
