The Netflix app for Android has a great new feature that is rolling out today: Smart Downloads. The feature, which is enabled by default, will delete an episode that you have downloaded and completed watching and will replace it with the next episode in the series that you have not watched. It means that you will automatically get the next episode in the series without having to manually go download it yourself.
Here is the scenario: Let’s say you watching Season 1 of The Crown and have downloaded the first four episodes in the series. When you complete episode one, it is deleted and episode five of the series is downloaded automatically to your phone. It means that you will always have four episodes downloaded and ready to watch.
