The sudden disappearance of the phone book on a Redmi smartphone causes panic, especially if important work or personal numbers are stored there. This problem occurs quite often among owners of Xiaomi and Redmi devices, and in most cases the data is not permanently deleted, but simply hidden or out of sync. Understanding the Android architecture and the features of the MIUI shell allows you to quickly find the cause of the failure and return lost entries.
The main reason for losing access to the list of subscribers lies not in the physical deletion of files, but in a display error or change in the data source. The system Android stores records in several possible locations: the internal memory of the device, on a SIM card or in a cloud account Google. If the Contacts app is set to show only one of these categories and the data is in another, the list will appear empty. Crashes can also occur after updating the firmware or accidentally changing the account.
Before taking drastic measures like resetting the settings, it is necessary to conduct a thorough diagnosis of the current filters and synchronization settings. In this article we will analyze a step-by-step algorithm of actions that will help restore access to numbers in 90% of cases without data loss. We will look at both the built-in tools Xiaomiand the capabilities of the Google web interface.
Checking display settings and filters in the application
The most common reason for “disappearing” numbers is an activated filter in the phone book application itself. The user could accidentally change the settings so that the phone shows contacts only from the SIM card, while all entries are saved in the phone memory or account. To fix this, open the application Contact and go to the settings menu, usually indicated by three dots or a gear.
In the menu that opens, find the item Displaying contacts or “Contact Filter”. Here you will see a list of available storage: phone, SIM card and Google accounts. Make sure that the checkbox next to “All contacts” is selected or all available storage sources are selected at once. Sometimes the system defaults to hiding duplicates or contacts without numbers, which can also create the illusion of an empty list.
⚠️ Warning: If you have recently installed third-party applications for calling or managing contacts, they may have intercepted access rights and changed the default display settings. Check the list of recently installed apps.
After changing the settings, be sure to close the application completely through the task manager and open it again. Often the interface does not update instantly, and a process restart is required com.android.contacts to apply the new filtering rules. If the list remains empty, proceed to the next stage of checking synchronization.
☑️ Display diagnostics
Diagnostics of synchronization with Google account
Most Redmi users save numbers in the cloud Google for security. If synchronization has been disabled or the connection has failed, the phone will stop downloading data from the cloud and the list will become empty. Go to section Settings your smartphone, then select Accounts and synchronization. Here you need to find your main Google account.
Click on the email address and make sure that the switch next to the “Contacts” item is in the active position. If it's off, turn it on and wait a few minutes. The system will begin downloading data from the cloud to the device. In some cases, you need to force synchronization: click on the three dots in the corner of the screen and select Synchronize.
What to do if synchronization is frozen?
If the synchronization process hangs in the “Waiting” status or gives an error, try deleting the account from the phone settings and adding it again. This will not delete data from the cloud, but will update access tokens and start downloading contacts from scratch.
It is worth considering that synchronization requires a stable Internet connection for it to work correctly. If you are in an area with poor reception or are using a limited network, the download may not start. Also check if your storage space is running out Google Drive, although this is a rare problem for text contact entries.
Recovery via the Google Contacts web interface
If you couldn’t find the numbers on the phone itself, the most reliable way is to check the cloud storage through a computer or the browser of another device. The service Google Contacts keeps a history of changes and allows you to roll back the state of the phone book back in time. This is an indispensable tool if contacts were accidentally deleted by a user or malware.
Go to the site contacts.google.com and log in using the same account as on your Redmi phone. If you see your numbers there, then your data is safe. You can export them to a file format .vcf and import them back into the phone, or simply enable synchronization as described in the previous section. The site allows you to manage duplicates and merge records.
One of the most powerful features is the ability to rollback changes. In the menu on the left, find the item Settings (gear) and select Undo changes. The system will prompt you to select a time period: 10 minutes ago, 1 hour, yesterday or a custom date. This allows you to restore contacts deleted even a few days ago.
| Recovery method | Difficulty | Efficiency | Prerequisites |
|---|---|---|---|
| Filter settings | Low | High | Access to the application menu |
| Google Sync | Average | High | Internet and account |
| Rollback changes (Web) | Average | Maximum | Access to a PC or browser |
| Recovery from MIUI Cloud | High | Depends on backup | Xiaomi account |
Google Contacts web interface shows the real status your database in the cloud, regardless of what is displayed on the smartphone screen.
Using the Xiaomi cloud service (Mi Cloud)
Device owners Redmi and Xiaomi have access to their own cloud service Mi Cloud, which can also store backup copies of contacts. If you have previously signed into your Mi Account and enabled syncing, your data may be there. To check, go to Settings → Mi Account → Xiaomi Cloud.
In the cloud management section, find the item Contact. If the switch is active, click on it to see details. Often the option to restore from a backup is available here. The system may offer to restore data from a backup made automatically before the last system update or reset.
⚠️ Attention: When restoring from the Mi Cloud, the current data on the phone may be replaced with data from the backup. Make sure that the cloud contains a more recent version of the phone book than the one currently (empty) on the device.
You can also check the availability of a backup through the web version of the service i.mi.com. Go to the site from your computer, enter your Mi account information and go to the contacts section. If the numbers are displayed on the website, you can export them and transfer them to your phone in any convenient way, for example, via Bluetooth or instant messenger.
Search for hidden and blocked numbers
Sometimes contacts are not deleted, but are moved to special lists, such as “Black List” or “Favorites”, if the grouping settings are lost. In the Redmi contacts application, there are functions to hide numbers from prying eyes. Check to see if privacy or guest access mode is enabled, which limits the visibility of a certain part of the phone book.
Go to the application settings and find the section Black list or “Blocked”. Although unwanted callers usually end up there, a software glitch may have mistakenly moved all contacts there. Also check the section Favorites: sometimes the interface switches to displaying only this group, hiding other subscribers.
Search by name or number at the top bar of the Contacts app. If the search finds an entry, but it is not visible in the general list, then the problem is definitely in the display filters or groups.
Another possible reason is damage to the contact database file. If the phone was abruptly turned off while recording a new number or updating the system, the file contacts2.db could be damaged. In this case, clearing the application cache may help the system rebuild the index. Go to Settings → Applications → Contact → Storage and click Clear cache. Do not confuse this with data clearing, which will delete everything local.
Local backup and recovery
MIUI shell has a built-in tool for creating local backups, which are saved in the phone’s internal memory. Even if cloud synchronization was not configured, you may have accidentally created a backup earlier. To access this data, open the application Settings, scroll down to About the phone and quickly tap on version MIUIseveral times to activate advanced features if they are hidden (in new versions this is not required, the path is straightforward).
An easier way: go to the application Security (green icon with lightning), which is preinstalled on all Redmi. Find the section below Backup and recovery. Here you will see a list of available backups with the dates they were created. If there is a backup made before the contacts disappeared, select it and start the recovery process.
Path to the backup files manually:
MIUI/backup/AllBackup/
If automatic recovery does not work, you can try to find the backup file manually through the file manager. Files usually have the extension .bak. However, simply copying them is not enough - you need to use a standard system recovery tool, since the data is encrypted and tied to a specific firmware version.
Where are the backup files stored?
Physically, the backup files are located in the MIUI/backup/AllBackup folder in the internal memory. If you made a backup to an SD card, the path will be similar on an external drive. Do not delete this folder when clearing garbage.
⚠️ Attention: The interface of the “Backup and Restore” menu may differ depending on the version of MIUI (12, 13, 14 or HyperOS). In some versions, this function is included in a separate application or hidden in advanced settings.
Local backup is your insurance in case of lack of Internet or problems with Google and Xiaomi servers. Regularly create copies before major updates.
Preventing data loss in the future
To prevent the situation of missing contacts from happening again, you need to set up automatic synchronization and regular backups. The best practice is to store the main database in your account Googleas this provides cross-platform access and reliable protection against device loss. Make sure that in your account settings there is a checkbox for automatic synchronization when connected to Wi-Fi.
It is also recommended to make a local backup once a month through MIUI tools and copy the backup file to your computer or another cloud storage (for example, Yandex.Disk or Dropbox). This will create an additional level of protection. Avoid storing important numbers only on the SIM card, as it has limited memory and does not allow you to store additional data such as addresses or photos.
- 📱 Always check which account is selected as the default account for saving a new number when creating an entry.
- ☁️ Enable two-factor authentication for your Google account to protect your data from unauthorized access and deletion.
- 🔄 After each major firmware update, check your synchronization settings, as resets may return factory settings.
Following these simple rules will allow you to feel confident and know that your contacts are safe. Technologies change, interfaces are updated, but the principle of duplicating important data remains unchanged to guarantee the user’s peace of mind.
Frequently asked questions (FAQ)
I reset the phone to factory settings, can I restore contacts?
Yes, if synchronization with the account was enabled before the reset Google or Xiaomi. Just log into the same account after setting up your phone and your contacts will be downloaded automatically. If synchronization was turned off, you can only restore data from a local backup, if you managed to make one.
Contacts are displayed on the SIM card, but not on the phone. What is the reason?
Most likely, the “Phone” or “Google Account” filter is selected in the “Contacts” application settings, and the SIM card is hidden. Go to the application settings, find the “Contacts display” item and select “All contacts” or select the SIM card separately.
Can I restore contacts if I don’t remember the password for my Google account?
Without access to the account, it is impossible to restore synchronized data. You will need to first regain access to your account through the password reset procedure on the Google website. If contacts were only stored locally on the phone and the phone was reset, then, unfortunately, the data is lost.
Why did some numbers disappear after the MIUI update?
A system update could reset filter settings or desync accounts. Less common is database corruption during installation. Check the display settings and force synchronization in the accounts menu.
How to transfer contacts from an old phone to a new Redmi?
The easiest way is to use the “Mi Mover” function or simply sign in to your Google account on the new device. You can also export contacts to a .vcf file on your old phone, transfer the file to a new one and open it for import.
