Official carousel app from Xiaomi.
This will help you get dynamic photos on your lock screen every time you turn ON your screen.
You can browse to know more about the story in a single tap, and the best part is you don't need to unlock. You can even watch videos, play lite games, browse through the content within the lock screen.
** Note that this app is not supported on Mi A1/A2 **
In the new version, you can get new stories on every screen ON, instead of unlocking. You can also swipe right to get details and get exciting stories.
The best part is that it is designed to use less battery and system resources and downloads the content in WEBP format to save on your data.
Go ahead and get rid of boring static wallpapers and explore the world of online content.
