Live wallpapers have been available in Android since Eclair 2.1. In the past, live wallpapers mostly engaged hardcore users and theming enthusiasts because of hardware limitations of phones, high battery consumption due to a constantly animated background, and lackluster animations. However, with the advancements in smartphone hardware, the feature has attracted several more DIY enthusiasts who like to use ports of live wallpapers from phones like the Google Pixel 3 or the Pixel 4. Recently, Xiaomi took the same approach as Google has been taking since the OG Pixel and added two live "Super" wallpapers with an aerial view (with four different scenes) of the Earth and Mars in MIUI 12 (our hands-on). The wallpapers were very well received due to the popularity and the reach of the brand, as compared to Google.
Xiaomi's "Super" wallpapers can also be installed on any Xiaomi or non-Xiaomi device. But if you find the availability of just four vistas limiting, we have Metropolis – an app that offers more than 100 different panoramas from different cities. The Metropolis app has been built upon the Unity 3D engine, which also drives popular mobile and desktop games.
The cities available in Metropolis are primarily from North America and Europe. The app includes noted landmarks such as the Empire State Building, the Statue of Liberty, Paris Las Vegas, and Bordeaux Cathedral. The live wallpapers in the app also support horizontal scrolling as you move from one page to another on the homescreen.

With the latest update, the developer has also added the zoom-in effects similar to Xiaomi's Super Wallpapers. You can enable or disable the effect from the Settings. If you desire, you can also change the animation speed, the level of zoom, the parallax effect, and the speed of horizontal panning.
