Following the release of the Pixel Tablet and Pixel Fold, Google wants developers to take big-screen apps more seriously. Asking nicely rarely works, so Google is changing the Play Store ranking algorithms to increase the visibility of apps that better support large screens.

Apps and games that adhere to our large screen app quality guidelines will now be ranked higher in search and Apps and Games Home. This helps users find apps that resize well, aren't letterboxed, and support both portrait and landscape orientations. Editors’ Choice and other curated collections and articles will also consider these criteria going forward, creating new featuring opportunities for optimized apps.
