Xiaomi and Redmi smartphone owners often face the need to transfer data or recover a lost phone book after resetting. Understanding the physical and logical structure of the number storage helps not only in migrating to a new device, but also in situations where manual data extraction from system files is required.
In the ecosystem MIUI And the new HyperOS uses a flexible synchronization system that can confuse the user, and the numbers can be physically stored in the phone's internal memory, on the phone. SIM-It's important to distinguish between these levels, because the methods of accessing them are radically different.
In this article, we will take a closer look at the Android file system used by Xiaomi and explain why it is impossible to see the contact database without root rights using standard file managers methods. You will learn how the com.android.contacts mechanism works and where to look for backups if the phone stops turning on.
Physical location of the contact database
From the point of view of the Android file system on which the MIUI shells are based, all contacts are stored in a special SQLite database, which is located in a secure system partition, access to which is closed to ordinary users and applications without extended rights.
The complete path to the file where the numbers are physically located is as follows:
/data/data/com.android.providers.contacts/databases/contacts2.dbIt's the file. contacts2.db It's a store of all the information, but you can't just copy it through a standard conductor. Android's security system blocks access to the folder. /data/data/. To work with this file, you will need root rights or the use of debugging by USB (ADB) permittingly.
⚠️ Note: Attempting to edit or delete a file contacts2.db Directly through the root file manager can cause the phone book to be lost completely and the system application Contacts malfunctions. Always make a full backup before tampering with system files.
If you have root access, you can use file managers like Root Explorer or MiXplorer to copy that file to save to your computer, and it's the most complete backup method, even storing hidden fields and contact-related call history.
What is inside the contacts2.db file?
Storage for SIM-map and local memory
Many users prefer to keep their numbers on SIM-The map, considering it a more reliable method when changing phones. - Xiaomi Redmi Note SIM-The card acts as a limited external carrier with its own file structure, independent of the main memory of the smartphone.
However, SIM-It's very limited. It usually only holds a name and a phone number, ignoring email addresses, extra numbers, addresses and photos. When you keep in touch with a SIM, it's physically written into the card chip.
- 📱 Local storage (phone memory) – contacts are stored in the same database contacts2.db, And this is the basic and most functional method.
- 💾 SIM-map is an outdated method with limited functionality, useful only for basic transfer between buttons and.
- ☁️ Account. Google/Mi — Virtual storage synchronizing the local database with the server.
To check where the new default numbers are saved on your Redmi, go to the Contacts app, click three dots in the corner and select Settings. There will be a "Save Default Location" option. Changing this setting affects which part of memory the new contact will fall into.
💡
It is recommended to always choose to save to your Google account or phone, but not to save to your phone. SIM-card so as not to lose additional data about the person during the transfer.
Cloud storage Mi Cloud and Google Contacts
Modern versions of MIUI give priority to cloud synchronization, which means that your contacts may not be stored as a single file on your phone, but exist as a data set on Xiaomi or Google servers.
If you have sync enabled in your settings, you only have a cached copy on your device. The original is in the cloud. For the Xiaomi ecosystem, it's Mi Cloud (i.mi.com) and for pure Android, it's Google Contacts (contacts.google.com).
You can check for a backup in the Mi cloud through your browser by logging in to your account, and you'll see an exact copy of your phone book, which is especially useful if your phone is broken or lost, and you can restore numbers on any other device by simply logging in.
It's important to understand the difference: if you delete a contact on your phone and sync is enabled, it will also be deleted in the cloud, so always export to.vcf before cleaning your phone book.
How to Recover and Recover Remote Contacts
Contacts disappear often, and this can be due to synchronization failure, accidental deletion, or a MIUI software glitch. Before you panic, it's worth checking the cart in the cloud services.
The Contacts app on Xiaomi often has a built-in shopping cart where deleted files are stored for up to 30 days, and the path to it is usually located in the app's settings menu or in the side-switch menu.
If there's nothing locally, use the web version of Google Contacts. There's a Cancel Change feature that allows you to roll back the status of your phone book a day, a week or a month, and it works like a time machine for your data.
| Method of recovery | Where to find | Storage period |
|---|---|---|
| MIUI basket | Appendix Contacts → Settings | 30 days |
| Google Contacts | contacts.google.com → Correction | Up to 30 days. |
| Backup copy of Xiaomi | Settings → About the phone → Reservation | Before reset or 90 days in the cloud |
| File.vcf | MIUI/backup/AllBackup folder on PC | Indefinitely |
To recover from the local MIUI backup, you will need a backup file, which usually lies along the path of MIUI/backup/AllBackup/contacts. If you did not manually backup, this file could be created automatically when you upgraded the system.
⚠️ Note: When you restore contacts from an old backup, make sure you do not create duplicate records.The system may suggest combining the same numbers, and this action is better confirmed.
Exporting contacts to a VCF file for secure storage
The most reliable way to ensure data security is to have a physical file on hand..vcf (vCard) is a universal standard that can be read by any phone, computer or email client.
To create such a file on Redmi Note, open the Contacts app, go to the settings and select Import and Export Contacts. Next, click Esport in the device memory.
The system will suggest selecting contacts for export. Once confirmed in the root directory of internal memory or in the folder MIUI/backup/AllBackup/contacts, a file with the extension.vcf will appear. This file can be sent to yourself by email, saved to the cloud disk or transferred to your computer.
☑️ Checklist of safe export
The advantage of this method is that the.vcf file is not tied to a specific account or version of Android, and you can open it in 10 years on any device, and it is the only guaranteed way to save data regardless of the cloud service policy.
Access problems and hidden contacts
Sometimes users can't find contacts because they're hidden by filters, and Xiaomi's Contacts app has a Hidden Contacts feature that allows you to hide numbers from prying eyes.
To see these numbers, you need to swipe down (or up, depending on the version of MIUI) and enter the previously set password for hiding. Without a password, these entries are not displayed or involved in a normal search.
The problem may also be in the contacts displayed, and in the display settings, you can choose to show contacts only with the SIM-cards or only from a particular account.If the filter is selected SIM", If the numbers are saved to Google, the list will be empty.
To solve the problem, go to the Display Settings and make sure that the check box "All contacts" or select all the necessary sources is a common reason for "lost" numbers after updating the system or changing the password from the account.
💡
If contacts are gone after reset but sync has been enabled, just add the same Google or Mi Account to the new phone’s settings and the data will pull up automatically.
