What to do if the Xiaomi Watch S3 can not receive incoming call reminders?

The incoming call reminder function is one of the functions enabled by default on the product. Please check whether the Mi Fitness App is running in the background (please check whether the background process lock, background self-starting, background high power consumption permission and other permissions are enabled), and the Bluetooth settings of the mobile phone. Check whether the "Bluetooth Audio" of the watch device is turned on (it is turned on by default. If this function is turned off, there will be no reminder for incoming calls).
