The sudden disappearance of the phone book is a stressful situation that many owners of Xiaomi and Redmi Note smartphones face: you take the device in your hands to dial a number, and instead of a list of subscribers you see a void or only a few old records, you should not panic at this point, because in 90% of cases the data is not irrevocably destroyed, but simply hidden due to a synchronization failure or display error.
Operating system MIUI, Android-based, has a complex data storage structure where contacts can live in different layers: SIM-The problem is usually in the desynchronization of these layers after a system update or network failure. Contacts removed from cloud storage more than 30 days ago, it is almost impossible to restore regular funds.
In this article, we will look at all possible causes of missing numbers and offer step-by-step instructions for returning them. We will look at both software methods for solving through interface settings, and deeper ways to restore through web versions of services. It is important to act consistently so that old backups are not overwritten with new, empty data.
The main reasons for the disappearance of the phone book
The first step is to understand what exactly happened, because synchronization is the main mechanism that keeps your data safe, but it can also cause it to disappear temporarily, and if you recently changed your Google account password or reset your network settings, your phone may lose communication with the server and stop displaying the current list.
Another common cause is human error or random action, and the user could unknowingly switch the display filter in the Contacts app, hiding the numbers saved on the site. SIM-Also consider the possibility of software failure of the contact application itself, especially if you have installed third-party launchers or system modifications.
Malware is not to be ruled out. Although Xiaomi has a powerful antivirus built in, installing applications from unknown sources can lead to viruses that block access to personal data. In rare cases, the problem lies in the damage to the file system after a failed firmware update.
⚠️ Warning: If you notice a contact loss immediately after you install a new app, delete it immediately and check your phone with antivirus.
Checking display settings and filters
Before you go into deep settings or panic, it's worth checking the basics. Often times, contacts are still there, the app interface just stopped showing them. Go to the Contacts app and find the menu button (usually three dots or bars in the corner of the screen) and select the "Display settings" or "Contact filter" option from the menu.
In the list that opens, you'll see all the available data sources. Make sure that the boxes are in front of all the boxes: "Phone","SIM-Map, Google, Mi Account. If a source is labeled "Hidden," the system will not show the numbers stored there. MIUI, When the settings are strayed into default.
💡
Use Favorites or create a temporary Test group to see if new numbers are retained at all, and if a new contact is maintained and seen, the problem is the filter of old records.
It also makes sense to check if the "Number Only" or "China Only" mode is enabled if you have a global or Chinese version of the firmware installed, respectively. Switching between these modes can instantly "return" or "hide" hundreds of records. Once you make changes, be sure to restart the device to apply the settings.
- 📱 Open the Contacts app on the home screen.
- ⚙️ Click on three dots in the corner and select "Display Settings".
- ✅ Make sure all storage sources (Google, Phone) are activated, SIM).
- 🔄 Reboot your smartphone to update the list.
Recovery through Google Contacts
The most reliable way to get back lost data is to use Google backups. If your Redmi Note has a Gmail account added and sync enabled, then all changes to the phone book are automatically saved in the cloud. Even if you delete the number on your phone, it can be stored in the cloud for some time.
To recover, go to contacts.google.com from your computer or other device using the same login as your phone. In the service interface, find the gear icon (Settings) and select "Cancel Changes." The system will suggest you select a time restore point: 10 minutes ago, an hour, yesterday or a date.
Recovery Path: contacts.google.com → Settings (cogs) → Cancel Changes → Select a Date → ConfirmOnce confirmed, all contacts will be restored as they were at the selected date. On the smartphone, you will need to wait for automatic synchronization or manually run it in the Settings → Accounts and Sync → Google. The process can take from 5 to 15 minutes depending on the number of records and Internet speed.
☑️ Checking Google Syncs
Importantly, the undo function only works within 30 days, and if contacts are missing six months ago, this method will not help, but for fresh losses, this is the gold standard for recovery. Once the data is returned successfully, it is recommended to export the backup in.vcf format and save it separately.
Using the Mi Cloud and Local Backups
Xiaomi owners have an additional tool, Mi Cloud, which is a proprietary cloud of the company, which often duplicates data from Google or stores it independently if you use a Mi Account, and you can check for a backup through your browser by visiting i.mi.com or through your phone settings.
In your smartphone settings, go to Settings → Mi Account → Mi Cloud → Contacts. Here you will see the date of the last sync. If the date is current, try to switch the sync slider: turn off, wait a few seconds and turn on again. This action will force the data from the server to update.
| Source of data | Remote storage period | Method of recovery | We need the Internet. |
|---|---|---|---|
| Google Contacts | 30 days | Function "Cancel changes" | Yes. |
| Mi Cloud | 30 days | Synchronization in settings | Yes. |
| Local backup | Indefinitely | Recovery from the file | No. |
| SIM-map | Before the re-recording | Importing to the phone | No. |
In addition to the cloud, MIUI automatically creates local backups of the system, and you can find them in the Security app → Backup and Recovery. If you've done backup before, you can try to restore only the Contacts section without touching the rest of the data. It's a secure operation, but it can take time.
Where is the backup file physically located?
Import and export contacts via VCF file
If the automatic methods didn't work, you should use manual file management. VCF (vCard) is the universal standard for storing contact information. If you have an old export file or you were transferring data from another phone, this file is the salvation.
To import, open the Contacts app, go to the settings and select Import/Export Contacts. Select the source Import from Storage (or Import from File.vcf). The system will prompt you to find the file in the device's memory. If the file is in the download folder or on the memory card, specify the path to it.
After selecting the file, the system will ask where to save the numbers: SIM-It is strongly recommended to choose a Google account in order to avoid future data loss problems. SIM-The card may be shortened by long names and additional numbers, as the SIM memory is limited.
⚠️ Note: When importing contacts from the file, you can create duplicates. Once the procedure is complete, use the "Combine duplicates" function in the contact settings to clear the list of repetitions.
It's also useful for transferring contacts between different phones, so you can create a file on a single Redmi Note, transfer it over Bluetooth or messenger to a new phone, and import it, which is faster and more reliable than air synchronization with poor Internet.
What to do if your contacts are missing after the update
Firmware update MIUI — Sometimes new versions of Android or shells contain bugs that disrupt the contact database. If the problem occurs immediately after the update, the first thing you do is take your time to reset to factory settings. Try clearing the cache of the Contacts and Contacts app. SIM-map".
Do it through Settings → Apps → All Apps → Contacts → Memory → Clear cache. It is important not to confuse with Clear all Data, although in the case of contacts stored in the cloud, this is also not scary – they will re-tighten up. But it is better to start with the cache.
💡
Clearing the cache of the Contacts app is secure and often solves the problem of missing numbers after a system update without requiring a complete phone reset.
If clearing the cache didn't work, check if you have a third-party theme, some themes may conflict with system fonts or icons to hide interface elements, switch to the standard theme "Classic" and check for numbers, and check for updates to the "Contact" app itself through the GetApps store or Google Play.
In extreme cases, if nothing helps and there are no backups, you can try third-party applications for data recovery by connecting the phone to a PC. However, the effectiveness of such programs is low if a long time has passed since the deletion or the phone has been actively used, overwriting memory sectors.
