How to Remove Numbers from Xiaomi Phone: From Contacts to Call History

Xiaomi phones store phone numbers in multiple places: local contacts, SIM-A map, a Mi Account cloud, a call log, even an app cache, and if you sell a device, transfer it to another person, or just want to clear your personal data, standard deleting through the contact menu will not be enough. Numbers can remain in hidden system files, backups or be synced again the next time you log in to your account.
