Xiaomi 10 manually selects the installation package point, but the previous update package cannot be found, which belongs to the setting problem. Open the phone, click Settings, enter Settings, select my device, and click the MIUI version above to enter. Enter this interface, click the intermediate version number 10 or so, and the page will show that the extended function has been turned on. Then click on the above three points, and you can see that the installation package settings are manually selected.
