Losing important phone numbers is a stressful situation that almost every smartphone owner has encountered. It’s especially annoying when contacts disappear after an accidental click or a system crash on devices Xiaomi i Redmi. However, it’s too early to panic: in most cases, data can be returned if you act quickly and competently. Modern operating systems Android and proprietary shells MIUI have built-in backup mechanisms, which many users are not even aware of.
Information recovery depends on where exactly your records were stored: in the SIM card memory, in the internal memory of the device or in a cloud service. If you simply cleared the call list or deleted duplicates, the chances of getting everything back are almost one hundred percent. We'll look at all the current methods, from built-in synchronization functions to using specialized software for deep memory scanning.
Before taking active steps, it is important to stop actively using your phone. Each new entry made after deletion may overwrite the memory sector where the old data was stored, making it impossible to recover. In this article we will analyze in detail the action algorithms for various data loss scenarios.
Checking the trash and archive in the Contacts application
The first place to look when you discover missing numbers is the built-in “Trash” or “Recently Deleted” function. Starting with certain versions MIUI, the company Xiaomi has introduced a mechanism for temporary storage of deleted objects, similar to what is in the photo gallery. This is the easiest and fastest way to return data without using third-party tools.
To access this section, you need to open the standard application Contact, which usually has an orange icon with a silhouette of a person. In the upper right corner of the screen, find an icon with three dots or a gear, which is responsible for settings and menus. In the list that opens, select Recently deleted or Trash.
All entries that have been erased in the last 30 days will be displayed here. The system automatically clears this folder after a month, so there is no need to delay checking. If you see the number you need, simply select it with a checkmark and press the button Recover at the bottom of the screen.
If the “Recently Deleted” folder is empty, this does not mean that the data is lost forever. They could have been deleted earlier than 30 days or synchronized with the cloud, from where they can also be retrieved.
It is worth noting that this function may be disabled in the privacy settings or simply absent on very old device models. Redmi. In this case, the system does not save deleted objects even temporarily, and you will have to move on to more complex recovery methods through accounts.
Recovery through a Google Contacts account
The vast majority of users Android link their devices to the ecosystem Google. This means that your contacts are automatically synced with the search giant's servers. Even if you deleted a number from your phone, a copy of it may be saved in cloud storage Google Contactsif synchronization was active at the time of deletion.
You don't have to use the phone itself to check this. Log in from your computer or any other device to the official website contacts.google.com. Log in using the same Gmail account that is used on your smartphone Redmi. The web version interface often provides more options for managing data than a mobile application.
- 🔍 On the left side of the screen, find the menu and select
Trash. Deleted contacts are stored there for up to 30 days. - 🔄 If the trash is empty, click on the gear icon at the top right and select
Cancel changes. - ⏳ Select a time period (10 minutes ago, 1 hour, yesterday or custom period up to 30 days) to which you want to roll back the state of the list.
The rollback changes function is a powerful tool that allows you to return your contact list to the state in which it was in the past. After confirming the action, the system will begin the synchronization process. On your phone Redmi you need to go to Settings → Accounts and synchronization → Google and make sure that the switch opposite the item Contact is active.
Function "Undo Changes" in Google Contacts overwrites the current list on your phone with data from the selected date, so new contacts added after that date may be lost.
After forcing the sync, open the contacts app on your smartphone and wait a few minutes. If the Internet connection is stable, the missing numbers should appear in the general list. This method is the most reliable for those who regularly use services. This service is deeply integrated into the shell Google.
Synchronization via Xiaomi Cloud (Mi Cloud)
Device owners Xiaomi And Redmi have an alternative and often more convenient backup tool - Mi Cloud. This service is deeply integrated into the shell MIUI and allows you to save not only contacts, but also messages, notes and call schedules. Checking this source is required if you have previously logged into your Mi account.
First, make sure that synchronization has been enabled. On your phone, go to the Settings → Mi Accountsection. Inside the account menu, find the item Xiaomi Cloud and then Data synchronization. Make sure the switch Contact lits blue. If it was turned off, the data in the cloud may be missing or outdated.
If synchronization was active, you can restore data in two ways. The first is directly on the device: in the same menu Mi Cloud click on the contacts icon and select the recovery option. The second way is through the web interface on the website i.mi.com. The functionality there is wider: you can view deleted entries and restore them selectively or en masse.
⚠️ Attention: When restoring from Mi Cloud, duplicate entries may occur if there are already similar contacts on the phone. After recovery, it is recommended to use the “Merge duplicates” function in the Contacts application.
The web version of the service allows you to manage contacts even without access to the phone itself, which is convenient in case of a broken screen or other technical problems with the device. Just enter your username and password for your Mi account, go to the contacts section and use the menu for recovering deleted items.
Import and export VCF files from a memory card
Many users, in the old fashioned way or for reliability, periodically make manual backup copies of contacts in the form of files in the .vcf (vCard) format. These files can be stored in the phone's internal memory or on a memory card microSD. If you have previously exported, the restoration will only take a few seconds.
Open the application Contact on your Redmi. Click on the menu (three dots or stripes) and select Import/export contacts. In the window that appears, select the option Import from storage. The system will automatically scan the device memory for files .vcf.
If the file is found, you will be asked to choose where to import the data: to your Google account, to your Xiaomi account, or to your phone memory. It is recommended to select cloud accounts for future automatic protection. After confirmation, the process of reading the file and adding entries to the address book will begin.
| File source | File path (example) | Reliability |
|---|---|---|
| Internal memory | /MIUI/backup/AllBackup/contacts |
Average (lost when resetting) |
| SD card | /Contacts/backup.vcf |
High |
| Messengers | Download folder Telegram/WhatsApp | Low (you need to search manually) |
| Attachments in letters to yourself | High |
Often backup files are created automatically by the system when updating the firmware or performing a full system backup. Check the folder MIUI/backup through the file manager. If you find a fresh file there, it will save your situation even without access to the Internet.
Using third-party software for deep recovery
If none of the cloud methods helped, and the phone recycle bin is empty, the last frontier remains - using specialized data recovery software. apps such as Dr.Fone, Tenorshare UltData or DiskDiggerscan the internal memory of the device for residual traces of deleted information.
The effectiveness of this method directly depends on whether superuser rights have been obtained on the device (Root). Without Root, apps can only scan cached thumbnails or data accessible via USB debugging, which significantly reduces the chances of success. With root access, scanning occurs at a low level of the file system.
⚠️ Attention: Obtaining root access on new smartphones Redmi may lead to loss of warranty and disruption of banking applications. Use this method only as a last resort.
The recovery process usually looks like this: you install the app on your computer, connect your phone with a USB cable, turn on debugging mode and start scanning. Debugging mode is activated in the menu For developers, which is hidden. To unlock it, you need to quickly click on the build number 7 times in the section About phone.
How to enable USB debugging?
Go to Settings → About phone. Quickly click on the “MIUI Version” item 7 times until the message “You have become a developer” appears. Then return to the main settings menu, go to “Advanced” → “For Developers” and turn on the “USB Debugging” switch.
It is worth understanding that no app gives a 100% guarantee. If the memory sector where the contact was stored has already been overwritten with new information (for example, you downloaded a large application or shot a video), the data cannot be restored. However, it’s worth a try, especially if the numbers are critical.
Preventing data loss and setting up auto-sync
The best way to deal with contact loss is to prevent the situation. Setting up automatic sync takes a couple of minutes, but saves hours of hassle in the future. Make sure that your Redmi is configured to save new numbers directly to the cloud, and not to the phone memory or SIM card.
When creating a new contact, the system usually asks where to save it. Always select an account Google or Xiaomi. If the default is Phone, change this setting permanently. Go to the application Contacts → Settings and find the item Default saving account.
☑️ Contact security checklist
It is also recommended to periodically check the synchronization status. Sometimes, due to a password failure or running out of cloud space, the stopping process may stop. Regular visual monitoring through the Google or Mi Cloud web interfaces will help make sure that your data is safe.
⚠️ Attention: MIUI settings interfaces may differ depending on the firmware version (Global, China, Russia). If you do not find the described items, use the search in settings by entering the word “Synchronization.”
Remember that a SIM card is an outdated and unreliable medium for a modern telephone directory. It has a limit on the number of characters in the name and number, and if the card is broken or the plastic is lost, the data disappears forever. Transfer all records to the digital cloud.
Frequently asked questions (FAQ)
Is it possible to restore contacts if the phone has been reset to factory settings?
Yes, this is possible, but only through cloud services. When reset, the local memory of the phone is completely cleared, and recovery apps from a PC are powerless here. You need to log into your Google or Mi account after setting up your phone, and the contacts will be pulled from the cloud automatically.
What should I do if I don’t remember the password for my Google or Mi account?
Without access to your account, it is impossible to restore synchronized contacts. You will need to use the procedure for restoring access to your account via the linked email or phone number on the official Google or Xiaomi websites. In this case, local VCF files remain the only chance.
How long are deleted contacts stored in the Google Recycle Bin?
In the Google Contacts service, deleted entries are stored in the Recycle Bin for exactly 30 days. After this they are deleted permanently. In Mi Cloud, the storage period may vary, but is also usually around a month. It is recommended to check the trash immediately after detecting a loss.
Will the contacts be restored if I insert my SIM card into another phone?
Only those contacts that are physically recorded on the SIM card chip. Modern smartphones do not save numbers to a SIM card by default. If your contacts were in the phone memory or the cloud, replacing the device or SIM card will not help to return them without the synchronization procedure.
