Where is the Redmi k30 small window mode set?

Global free window is an excellent solution proposed by MIUI 12 for mobile phone multitasking. Through the global free window, you can quickly reply to messages on any interface, or hang applications in the corner to view. Function location: Settings >> Functions >> Free Small Window.

When a communication message is received, a small window can be opened by pulling down the floating notification (the notification floating window needs to be opened). After the small window is opened, you can hold down the top control lever to drag the position of the small window, slide up from the bottom to exit the small window, and slide down to display the small window in full screen.

If you move the small window to the four corners of the screen, you can hang the small window (mini small window function). When hanging a small window, the volume will be smaller, but the hanging position can only be at the four corners of the screen, and you can't drag it at will.

If you want to open a small window manually, you can enter the background multitasking interface, click the "Small Window Application" button in the upper left corner, and the applications that can open a small window at present will be displayed. Click Edit in the upper right corner to edit which applications are quickly displayed in small window applications, and you can add up to ten quick small window applications.
