Where Xiaomi Stores Contacts: System Folder Search and Backup

Have you ever lost contacts after resetting your settings or updating your firmware on Xiaomi? Or just want to know where your phone numbers are physically stored in your device's memory? Unlike photos or music, contacts don't lie in the DCIM or Downloads folder that you can access -- they're hidden in the Android system partition, which is not easy to get to without root rights.

In this article, we will learn which folder Xiaomi stores contacts in, how to access it (including without root), and what to do if the database file is corrupted. You will also learn how to manually export contacts in.vcf or.db format so as not to lose them when you flash or change your phone. The instructions are relevant for all models, from Redmi Note 10 to Xiaomi 14 Ultra, regardless of the version of MIUI.

Where to store contacts on Xiaomi: a system path to the database

Contacts on Xiaomi smartphones (as well as on other Android devices) are stored in the SQLite database with the extension.db. The main file is called contacts2.db and is located in the following way:

/data/data/com.android.providers.contacts/databases/contacts2.db

Important: this folder is located in a secure system partition /data, which is not available without root rights or special tools. Even if you connect your phone to your computer in MTP mode, you will not see this path in Windows Explorer or macOS.

📞 All saved phone numbers (including duplicates)
👤 Names, surnames and additional fields (email, addresses, birthdays)
🏷️ Contact groups (e.g., “Family”, “Work")

If you have root access, you can copy the file manually, and without root, alternative ways are to use ADB or specialized backup applications (discussed below).

How to find a folder with contacts without root rights

If you don't have root, you can't get direct access to /data/data/... but there are workarounds. Here are 3 working methods for retrieving contacts:

1.Across ADB (Android Debug Bridge)

The ADB tool allows you to back up system data, including contacts.

Enable USB Debugging in the Developer Settings (Settings → About Phone → MIUI Version – Press 7 times, then return to Additional → For Developers).
Connect your phone to your PC and execute the command: adb backup -f contacts.ab -noapk com.android.providers.contacts
On the phone screen, confirm the creation of a backup (password can not be set).

The contacts.ab file will be saved to your computer. To retrieve contacts2.db, use the Android Backup Extractor (Abe) utility.

2. through the "Google Contacts" app

If your contacts are synced with your Google Account, they can be exported in.vcf format:

Open contacts.google.com on PC.
On the left menu, select Export.
Specify the format (Google CSV or vCard) and click Export.

This method does not allow access to the file itself. contacts2.db, It allows you to keep all the numbers in readable form.

3. Through third-party applications

Applications like Super Backup & Restore or My Contacts Backup can back up contacts in.vcf or.xml format without root, but they don’t extract the original database file, they only export the data to a compatible format.

Check if sync with Google Account is enabled|Install. ADB-PC drivers|Download Android Backup Extractor (if you use it) ADB)|Create a folder for backups on your computer|Disable battery optimization for the Contact app"

File structure contacts2.db: inside the contact database

File. contacts2.db — It's a SQLite database, which is made up of several tables:

Title of the table	Description	Example of data
raw_contacts	List of raw contacts (each contact may have multiple records)	_id=1, account_name="Google", account_type="com.google"
data	Specific data (numbers, email, addresses)	mimetype="vnd.android.cursor.item/phone_v2", data1="+79991234567"
groups	Contact groups (e.g., “Friends”, “Colleagues”)	title="Family", notes="Family"
phone_lookup	Index for quick search by number	normalized_number="+79991234567", contact_id=1

To view the contents of the database, use programs like DB Browser for SQLite or SQLiteStudio. Please note: manual editing of the file is not recommended - this can lead to data corruption.

The critical detail is that if you delete the contacts2.db file, the system will recreate it the next time you run it, but all contacts will be lost.

What to do if contacts2.db is damaged?

If the database file is corrupted (for example, due to a failure during the update) MIUI), The contacts may be displayed incorrectly or disappear altogether: 1. Try clearing the cache of the Contacts app in the settings (Settings) → Annexes → Contacts → Memory. → Clear the cache). 2. If it doesn’t work, delete the app data (this will delete all local contacts, but synced with Google will remain). 3. In the extreme, restore the backup through ADB or reflash the phone with data storage (fastboot) -w Don't use it, it'll erase everything!).

How to Transfer Contacts from One Xiaomi to Another

If you change your smartphone (for example, from the Redmi Note 11 to the Xiaomi 13T), you can transfer contacts in several ways:

🔄 Sync with Google Account: the easiest method: just log in to the same account on a new phone, and contacts will be automatically downloaded.
📱 Export/import via.vcf: On the old phone: Contacts → ⋮ → Contact management → Exports/imports → Export to file. Transfer the contacts.vcf file to a new phone (e.g., via Bluetooth or the cloud). On a new phone: Contacts → ⋮ → File-based import.

Backup through MIUI:

Settings → Additional → Backup and Reset → Local Backup

⚠️ Note: when importing.vcf to a new phone, duplicates are possible if contacts are already synced with Google. Before importing, check if sync is enabled to avoid repeats.

💡

If some contacts don’t show up when importing.vcf, try opening a file on your computer in a text editor (like Notepad++) and checking it for correctness. Sometimes Cyrillic characters or special characters break the format.
