How to turn on the wallpaper carousel on Xiaomi Redmi 7A: a step-by-step guide with a photo

Automatic wallpaper change (or "carousel") on Xiaomi Redmi 7A is a feature that allows your smartphone to update the background pattern on the lock screen or home screen daily. Instead of a static image, you get a dynamic gallery where photos change on a schedule or with each unlocking of the device.

The feature is especially useful for those who like variety: it eliminates the need to manually select new wallpapers and customize them. Image sources can be both built-in MIUI collections and your personal photos from the gallery. On Redmi 7A (with MIUI version 10/11/12), the carousel works through the Theme app, but has a number of nuances that many users are unaware of.

It is important to understand that on Xiaomi budget models (including Redmi 7A), the functionality of the carousel can be limited compared to flagships, for example, there is no support for live wallpaper with animation or weather widgets in the background, but basic options are available: time change, random order and category selection (nature, cities, abstractions, etc.).
