Why doesn't the incoming call alert on the watch display the caller name?
Open the Amazfit app and toggle on the "Show Contact Information" option on the "Profile"->"Amazfit T-Rex"->"Incoming call " page. When the mobile phone receives an incoming call, the caller name will be displayed on the watch.
Please check the setting and application management on your phone to make sure Amazfit APP is given permission and allowed to read your contacts.
Please add in every contact number the country prefix.
Please also check if there is "-" or other hyphens in the contacts and phone number.
If you install other management software on your phone, please make sure you allow Amazfit app to read your contacts.
