Losing important numbers or having to move a phone book to a new device often puts Xiaomi users in the position of the data, and unlike the photos or music files we’re used to seeing in DCIM or Download folders, contacts are a structured database hidden from the eyes of the average user.
Android, which is mounted on the shell of MIUI or HyperOS, takes a specific approach to storing personal information, and understanding where these files are located is critical for those who plan to do a full backup of the system or try to recover data after a crash.
In this article, we will take a closer look at the file structure, look at the paths to system databases, and explain why simply copying folders may not give the desired result without root rights.
System architecture of data storage in Android
The Android operating system is based on the Linux kernel, which implies a strict hierarchy of files. All user data, including contacts, is by default in a secure memory partition, access to which is limited by the rights of the superuser, this is done to ensure security and prevent the accidental deletion or theft of personal information by malware.
The main contact repository is the SQLite database. The files in this database are usually.db and contain not only phone numbers, but also names, email addresses, photos and social profiles. On Xiaomi Redmi devices, this database is dynamically updated with each change in the phone book.
⚠️ Warning: Direct editing of database system files without backing up may result in the complete inoperability of the Contacts application and the loss of all records.
It’s important to understand that the path to these files depends on the operating system version and the specific smartphone model. Modern versions of Android (starting with 11 and above) have further restricted access to system folders even for applications with advanced rights, making direct access to files even more difficult without the use of special debugging tools.
💡
Use built-in sync with Google Account or Mi Cloud to automatically back up so you don’t depend on the integrity of your system files.
The exact path to contact database files
If you have root rights or you use a file manager with access to the system partition, you can find the database file in a specific path.
/data/data/com.android.providers.contacts/databases/This directory usually contains files with names like contacts.db, contacts.db-journal, or contacts2.db. It's the file. contacts2.db Most often it is an actual database on modern versions of Android in Xiaomi smartphones.
It is worth noting that on some Redmi models with caste shells, the path may differ slightly, for example, including the service provider prefix or specific user identifiers. /data/data/[package_name]/databases/ remains unchanged for native applications of the system.
- 📂 contacts2.db — The main database containing all relevant records.
- 📄 contacts.db – often a backup or outdated copy of the database.
- 🔒 permissions – access permission file critical to application operation after transfer.
To extract these files by the usual means of the file manager, you can't do without superuser rights. /data/data/ for all applications except system.
☑️ Verification of access to the database
The impact of account type on contact location
On Xiaomi smartphones, contacts can be stored in three different locations, and the physical location of the database file depends on the default account chosen to save.This is a key point that users often miss when searching for files.
If the contacts are saved in a Google account, they are physically in the system database described above, but synced with the Google cloud. SIM-card, data is stored in a separate file, often in.vcf format or in a specific SIM card database, the path to which may differ:
/data/data/com.android.providers.telephony/databases/The third option is Mi Account, where the data is also logged into the local database, but synchronization is prioritized to Xiaomi servers, and it is important to identify the source correctly to find the files you want.
| Storage type | Location of the file | Risk of loss | Synchronization |
|---|---|---|---|
| Telephone (Localno) | /data/data/com.android.providers.contacts | High (on discharge) | Absent. |
| Google Account | Local cache + Cloud | Low. | Automatic. |
| SIM-map | SIM/Telephony DB Memory | Medium (physical wear and tear) | Hand-held |
| Mi Account | Local cache + Mi Cloud | Low. | Automatic. |
The choice of storage location affects not only security, but also the speed of the application "Contacts" with a large number of records.
Using ADB to access the contact database
For users who don’t want to root but need access to the file system, there is an Android Debug Bridge (ADB) tool, which allows database dumps to be made via a computer using USB debugging.
First, you need to activate the developer mode. To do this, Xiaomi Redmi needs to quickly click seven times on the build number in the About section. Then in the Developer menu, you turn on USB Debugging.
And if you connect the phone to a computer, you can run a command to copy the contact database to the computer memory, and the command is as follows:
adb pull /data/data/com.android.providers.contacts/databases/contacts2.db C:/contacts_backup.dbThis method requires that the device does not have the additional ADB restrictions that are sometimes implemented by the manufacturer to improve security.Some versions of MIUI may require unlocking the bootloader for full access.
⚠️ Attention: Teams ADB An error in the command syntax can result in the system files being deleted instead of copied.
The resulting.db file can be opened on your computer using SQLite software such as DB Browser for SQLite to view, export, or edit content.
Recovery and conversion of the database
The contacts2.db database file is not a universal format like.txt or.jpg. It often requires conversion to the standard vCard (.vcf) format to be used on another device or application.
If you simply copy a database file to another phone, it won’t appear in the phone book automatically; the system has to “import” that data, the easiest way to do this is by opening the file through a special importer application or restoring it to the original directory with the correct access rights (chmod 660).
For conversion via PC, use the above mentioned DB Browser. Open the file, go to the Data Review tab, select the data table, or raw_contacts and export in CSV, which can then be converted to vCard.
Problem with the encoding during recovery
Alternatively, using built-in recovery tools, if the database file is placed in the correct folder, you can try to clear the Contacts app data through your Android settings, which sometimes triggers the database rereading process, but this method is risky.
Alternative export methods without access to system files
Because direct access to /data/data/ is difficult, most Xiaomi users use regular export facilities, creating a copy of the database in a custom format that is easy to migrate.
Open the Contacts app, click three dots in the corner or the menu button, and select Import/Export Contacts. Select Export to Storage. The system will create a 00001.vcf file at the root of internal memory or in the MIUI/backup/AllBackup folder.
- 📤 Export v.vcf – creates a universal file readable by any smartphone.
- ☁️ Synchronization is the most reliable way that does not require working with files.
- 💾 Mi Mover – Xiaomi’s proprietary utility for transferring contacts to new devices.
This approach eliminates the need to deal with access rights and the risk of damage to the system partition..vcf file can be sent to yourself by email, saved to the cloud or transferred over Bluetooth.
💡
The safest and most effective way to keep your contacts on Xiaomi is to sync regularly with your Google Account, not manually copying your system databases.
