Instant Apps, which allow you to try new pieces of software before fully installing them, are now showing up on Google Play. You’ll notice the feature is available if a “try it now” button appears on an app’s listing. If you tap it you’ll get to trial the app without a download.
This feature only exists for a select number of apps right now, but it’ll expand over time.
Google has also updated the store by adding trailers to the games area and sections for new and premium paid games.
