One of the big advantages of Amazon's video-streaming service has always been the ability to download its content on mobile devices. That way, if you're taking a flight, or just want to save on battery, you can watch films and TV shows without having to connect to the internet. Now, Amazon has made a small but significant tweak to this feature, adding the ability for Android users to download content directly to their SD cards.

This means that users that want to download, say, the whole of Mr. Robot season one, won't have to juggle their files, moving them about from main to removable storage as they run out of space. Instead, they'll just go straight into the latter. The feature is available on Android tablets and smartphone starting today in the US, UK, Germany, Austria, and Japan. And although it's hardly a deal-breaker if you're deciding between video-streaming services (Netflix's selection is still much better than Amazon's), it's certainly a nice perk.
