Accidental deletion of a phone number is one of the most common problems faced by owners of Xiaomi, Redmi and Poco smartphones, often when quickly clearing the list of callers or during replacement. SIM-It's a map where the user inadvertently erases important data. MIUI HyperOS provides several levels of information protection, which allows you to return lost in most cases.
Before you panic, you need to know where the information was stored: in the device memory, on the SIM card or in the cloud account, which directly depends on the choice of recovery method. Modern smartphones automatically create backups, but sometimes manual intervention is required to extract data from system folders or external services.
In this article, we will take a look at all the available algorithms, from simple checks of display settings to the use of specialized software. You will learn how to check the “basket” of contacts, recover data through a Google account and what to do if the phone was reset to factory settings.
Checking the display and synchronization settings
Often, the contact didn't disappear, but simply stopped showing because of the filters in the phone book that were lost. Android allows you to hide certain groups of contacts, such as only with a phone book. SIM-If you've recently changed your settings or updated your firmware, the filter may have reset by default.
To check, you need to open the standard Contacts app and go to the settings menu. It's usually hidden behind three dots or bars in the corner of the screen. Find the "Contact Display" or "Contact Filter" and make sure that the "All Contacts" check box is ticked. If you select the "Telephone Only" option, then the numbers saved on the SIM or in the cloud will not be visible.
It’s also worth checking sync status, as sometimes the data is in the cloud but not uploaded to the device. Go to Settings → Accounts and Sync and select your Google account. Make sure the switch opposite Contacts is activated. If it’s been turned off, turn it on and press the sync button right now.
- 📱 Open the Contacts app and click on the menu (three dots).
- 👁️ Select "Display Settings" or "Filter».
- ✅ Make sure that the All Contacts mode is activated».
- 🔄 Check the sync status in the Google account settings.
If the number didn't appear after turning on all the filters, it may have been physically deleted, however, eliminating software display errors is the first and most important step, which often saves the user time.
Restore Contacts through Google Contacts
The most reliable way to recover lost data is to use the Undo Changes feature in Google Contacts, which works like a time machine, allowing you to roll back the status of the phone book to any point in the past (up to 30 days ago), which is especially true if you accidentally deleted a whole group of numbers or cleared the list before selling a device.
To do this, you will need a computer or any other smartphone with Internet access. Go to the official website contacts.google.com and log in under the same account that was used on your Xiaomi. In the upper left corner, click on the gear icon (“Settings”) and select “Cancel Changes”.
In the window that opens, the system will suggest you to select a time interval: 10 minutes ago, 1 hour, yesterday or-custom (configurable). Select the period preceding the moment of deletion. Once confirmed, the system will restore all contacts that existed at the selected date. In a few minutes, the data will automatically be downloaded to your phone if you have Internet.
⚠️ Attention: Restoration through Google completely replaces the current contact list with the one that was on the selected date.If you added new numbers after deleting the old ones, they may disappear.
This method is most effective for users who have had automatic sync enabled, and even if you deleted a contact on your phone a week ago, it could have been stored in the cloud in a history of changes, making it easy to return without using third-party software.
Use of the basket in MIUI and HyperOS
The MIUI shells and the new HyperOS have an inbuilt random removal protection feature similar to the one found in the PC operating systems. When you manually remove a contact, it doesn't get erased permanently, but moves to a special buffer where it's stored for 30 days. That's the gold reserve for Xiaomi owners.
To get to the shopping cart, open the Contacts app on your smartphone. Click the three dots in the top right corner to call the menu and select Recycle Bin (sometimes called Recently Deleted) and it will show a list of all the numbers deleted in the last month. Find the contact you want, click on it and select Restore.
It's important to note that if you deleted a contact more than 30 days ago, it will automatically disappear from the cart forever, and the cart will be cleaned when you reset your phone to factory settings or manually clean the app's storage, so you need to act quickly without putting off the recovery in a long drawer.
- 🗑️ Open the Contact App on your Xiaomi.
- 📂 Go to the menu and select the "Basket" item».
- ↩️ Find the number you want and click “Restore».
If the cart is empty and you need contact, you will have to resort to more sophisticated methods related to backups or third-party software. However, in 80% of cases, if the deletion occurred recently, this built-in mechanism saves the situation.
💡
Check your contact basket regularly once a month to remove really unnecessary entries and make room in the system buffer.
Recovery from local backup of Mi Cloud
Many Xiaomi users ignore the Mi Cloud settings, relying only on Google, but the company’s built-in cloud often stores more detailed copies of the system data. If you had a Mi Account enabled, then contacts could be saved there even if sync with Google was disabled.
You can check for a backup via the web interface. Go to i.mi.com and log in to your Mi Account. Select Contacts. If your numbers are displayed, you have a copy. You can manually copy the data you want or sync your phone.
To recover through your phone settings, go to Settings → Mi Account → Cloud → Contacts. Make sure the sync switch is active. If the data hasn’t been updated for a long time, try turning off and back on sync to initiate a forced download of data from the server.
| Parameter | Google Contacts | Mi Cloud | Local backup |
|---|---|---|---|
| Storage period | Up to 30 days (rollback) | Indefinite (as long as there is room) | Before resetting or deleting the file |
| We need the Internet. | Yes. | Yes. | No. |
| Difficulty | Low. | Medium | Tall. |
| Risk of data loss | Minimum | Minimum | High (depending on the user) |
The advantage of Mi Cloud is deep integration with the system, for example, when changing your phone to a new Xiaomi, it is easy to log in to your account, and all contacts, notes and schedules will be downloaded automatically, without the need for additional manipulation of files.
Search for local backup files
Xiaomi smartphones automatically create local backups of the system, including contacts, if this feature was not disabled by the user.These files are stored in the internal memory of the device and can survive even deleting contacts if the backup file itself was created earlier.
To find these files, open the File Manager app and follow the MIUI → backup → AllBackup path. There may be folders with backup dates. Inside the folders, look for files with the.bak or.db extension that may contain the contact database, but you can't just open them - you'll need a recovery procedure through the phone menu.
To start recovery, go to Settings → About Phone → Reservation and Restore → Mobile Device. Enter the screen unlock password if needed. If the system detects available restore points, it will prompt you to select the date and type of data (contacts, messages, call logs) to return. Select only contacts so as not to overwrite other data.
⚠️ Attention: Restoring from a local backup can overwrite current data on your phone. If you are not sure of the date of the copy creation, it is better to export the current contacts to the file.vcf to your computer first.
☑️ Checking local backups
This method requires care, because it's easy to get confused about the dates of copy creation. If you regularly backup before installing applications or updating the system, the chances of success are very high. Old backup files can be stored for months until you manually delete them to free up space.
Use of third-party software and SIM-card
If the built-in tools do not help, you can try to extract data directly from the SIM-While modern smartphones rarely store contacts on the default SIM, old records could have stayed there, especially if you rearranged the card from an old phone.
For verification SIM-Open the Contacts app, click on the menu and select Import/Export Contacts. Select Import from SIM-The system will scan the chip's memory and suggest a list of numbers found to store in the phone's memory.
In more complex cases, when the phone has been formatted, PC programs such as Dr.Fone, Tenorshare UltData, or PhoneRescue can help. They scan the device's internal memory for residual pieces of data. USB (USB Debugging in the menu "For developers».
- 💾 Connect your phone to your computer via the original cable.
- 🔌 Enable debugging mode on USB developer-setting.
- 💻 Run a recovery program on your PC and follow the instructions.
- ⏳ Wait for the scan to finish (may take up to 30 minutes).
The effectiveness of third-party software depends on whether the memory was overwritten with new data. The less you used the phone after deleting, the better the chances of success. If the phone was actively used, new photos and applications could take the place of remote contacts, making recovery impossible.
Why don’t programs always find contacts?
Preventing Data Loss in the Future
To never face the problem of losing numbers again, you need to set up an automatic security system. Manual number saving is a risk that is not justified in the era of cloud technology. Configure your phone so that every new contact goes to the cloud immediately.
Go to the Contacts app settings and find the default location. Select your Google account or Mi Cloud. Now, when you add a new number, it will automatically sync with the Internet, and even if the phone falls into the water or breaks, the numbers will remain online.
It's also useful to export contacts once a month to a file. Go to Import/Export, select Export to Storage, and save contacts.vcf. This file can be sent to yourself by email or saved to a cloud drive. Having such a copy is a 100% guarantee that you will never be left without communication.
⚠️ Warning: Don’t store a single copy of your contacts in your phone’s memory. Always duplicate important data in the cloud or on external media.
💡
Automatic synchronization with a Google account is the only reliable way to ensure the safety of contacts in case of any system failures.
If you follow these simple rules, you can forget about the fear of data loss. Technology offers many tools to protect your data, and it's a sin not to use them. Set up your Xiaomi correctly once, and it will keep your data safe for years.
