With the two smartphone line Pixel Google introduced a custom launcher, officially not available for other phones, but can be installed manually with APK file . Concurrently, the group of Mountain View has also released the application Wallpapers which as we understand from the name is dedicated to the customization of the homescreen (and lockscreen). Now you can download it completely free of charge on any device Android directly from the platform Android 7.0 Nougat (or later). Finally, you can select a specific category and receive every day a new background. This is the official description.
Customize the screen as you like with beautiful backgrounds and advanced features. Choose one of your photos, an image of the collection of Google Earth, a spectacular landscape of Google+ and more. You can change it whenever you want because the screen always talk about you and your style.
To launch it you need to make a long-click a free space on the main screen and then select “Wallpapers”: no icon is in fact included in the menu of the installed app. Between categories of images present include Earth, Nature, City, Life and Texture. The catalog, as stated by bigg, will be continuously updated and enriched by new entry. Below are some screenshots showing the interface.
