Xiaomi Redmi 9 is one of the most popular budget smartphones, but even its users are faced with the need to clean the phone book. Maybe you are selling a device, want to get rid of duplicates or just clean up the contact list. In this article, we will discuss all possible methods of removal, from basic to radical, including the nuances of working with MIUI 12/13 and synchronization through Google.
It is important to understand that simply clicking Delete in the Contacts app does not always solve the problem. Contacts can be saved in the cloud, duplicated between accounts or recovered after a reset. We will explain how to guarantee to erase data without the possibility of recovery, if necessary (for example, before selling a phone).
This article is relevant for all Redmi 9 modifications (including Redmi 9A/9C/9T) based on MIUI 11-14 and Android 10-12. If you have another firmware, check the compatibility of methods in the relevant sections.
