In this article, we will take a closer look at where Android contacts are physically stored on Xiaomi devices, how they are organized in the system, and what to do if you need to manually copy or restore the contact database (contacts2.db), And also how synchronization with Mi Account and Google affects the safety of your data. MIUI 12/13/14 and the nuances of working with root rights.
Physical location of contacts in Xiaomi memory: the way to the database
All contacts on Xiaomi smartphones (as well as other Android devices) are stored in a special SQLite database called contacts2.db. This file is in a secure system folder, access to which is limited without root rights. However, knowing the exact path will help when backing up through ADB or file manager with root access.
The main paths to the contact file:
- 📁 For Android. 10 newer (MIUI 12/13/14): /data/data/com.android.providers.contacts/databases/contacts2.db
- 📁 For older versions of Android (before) 9 inclusively): /data/com.android.providers.contacts/databases/contacts2.db
- 🔄 Backup copies MIUI: /MIUI/backup/AllBackup/ (if automatic reservation is enabled)
It is important to understand that the file contacts2.db It contains not only phone numbers, but also all the related information: names, email addresses, birthdays, tied social media accounts and even call history (in some versions). MIUI). The size of this file can range from a few kilobytes to tens of megabytes depending on the number of records.
⚠️ Attention: Direct file editing contacts2.db Without specialized tools (e.g., SQLite Editor) can cause database damage and loss of all contacts!

It is worth noting that exporting to.vcf does not store all meta-information (for example, call history or account attachment), but it is universal and compatible with any device. contacts2.db, Contains complete data but requires special programs to view (e.g, DB Browser for SQLite).
Contact Sync: Mi Account vs Google vs Local Storage
On Xiaomi smartphones, contacts can be stored in three main repositories:
| Storage type | Where data is physically stored | Pluses | Cons |
|---|---|---|---|
| Locally (on the phone) | /data/data/com.android.providers.contacts/databases/contacts2.db | It is not dependent on the Internet, full control over data. | Risk of loss when a phone is dropped or broken |
| MI Account (Xiaomi Cloud) | Xiaomi servers (China/Singapore/Russia) | Automatic sync, access from any Xiaomi device | Limited space (5GB free), possible synchronization delays |
| Google Contacts | Google Servers (USA/EU) | Cross-platform, integration with Gmail, reliability | Google account required, possible problems with Chinese firmware MIUI |
