Deleting all contacts on Xiaomi Redmi 10

Smartphones of the line Xiaomi Redmi 10 often become reliable assistants in everyday life, accumulating huge databases over years of use. Sometimes there is an urgent need to completely clear the phone book: before selling a device, when transferring a gadget to another family member, or simply to eliminate software synchronization errors. The process of manually deleting hundreds of entries can take hours and lead to accidental deletion of desired numbers if you are not careful.

In this article, we will look at the most effective and safe ways to delete all contacts from your Android devices in a matter of minutes. We will analyze the options both through the built-in system settings and using Google cloud services, which are often a hidden storage of duplicates. It is important to understand that the choice of method depends on where exactly your records are stored: in the phone memory, on a SIM card or in a Google account.

Before taking drastic measures, make sure that you have an up-to-date backup copy of your important data. Despite the fact that the deletion operation is reversible within a short time through the recycle bin, the risk of losing unique information is always present. Next, we will describe each step in detail so that you can choose the optimal scenario for your situation.

Preparation for deletion and backup

Any mass deletion of data requires preliminary preparation to avoid irreversible consequences. On smartphones MIUIinstalled on Redmi 10, contacts can be duplicated in different sources, and simply pressing the “delete” button in the phone book does not always clear everything completely. First you need to determine the priority of saving information.

It is recommended to create an export of the phone book to a file format .vcf. This is a universal format that can later be imported into any other smartphone or restored on the same device. To do this, open the Contacts application, click on the three dots in the corner of the screen and select Import/Export contacts. Select the option to export to internal memory or an SD card.

It is also worth checking the synchronization status with your Google account. If the feature is enabled, deleting contacts on your phone will automatically remove them from the cloud, and they may come back the next time you sync. To prevent this, you need to temporarily disable synchronization or delete data from the cloud separately.

⚠️ Attention: If you plan to sell your phone, simply deleting contacts is not enough. Attackers can recover deleted data using special software. In this case, a full reset to factory settings is necessary.

Deleting contacts through the built-in application

The most obvious way to clear the phone book is to use the standard MIUI interface. However, the interface may change depending on the firmware version, so it is important to know the exact sequence of actions. Open the application Contact on the home screen or in the all applications menu.

In the upper right corner of the screen, find the icon with three vertical dots or the "More" button. Select "Batch delete" or "Delete contacts" from the drop-down menu. The system will prompt you to select a source: phone, SIM card or Google account. For complete cleaning, you will need to repeat the procedure for each source separately.

After selecting the source, click on the selection icon (usually a check mark or square in the corner of the list) to select all entries at once. Some versions of MIUI have a "Select All" button that instantly marks the entire phone book. Confirm the action by clicking on the cart icon.

The system will ask you to confirm the operation, since it is irreversible without a backup copy. Click "OK" or "Delete". The process may take several seconds if there are thousands of records in the database. When completed, the list should be empty.

Cleaning through Google account settings

Users often forget that the bulk of contacts on modern Android smartphones, including Redmi 10, are stored not in the device’s memory, but in the Google cloud profile. This ensures the safety of data if you lose your phone, but complicates the process of complete deletion.

To delete contacts permanently, you need to go to your account settings. Go to Settings smartphone, then select the "Accounts and synchronization" section. Find your Google account in the list and click on it. Here you will see a switch for syncing contacts.

If you simply turn off synchronization, the contacts will remain on the phone, but will no longer be updated. To delete, you need to either delete the account from the device (which will delete all data associated with it), or go to the website contacts.google.com through a browser and clear the list there. After cleaning in the cloud, you need to click “Sync” on your phone for the changes to be applied locally.

Deletion method	Impact on the cloud	Difficulty	Risk of recovery
Via application Contacts	Deletes from the cloud (if synchronization is enabled)	Low	High (via Google Recycle Bin)
Deleting an account	Deletes a local copy, cloud remains	Medium	Low (cloud data)
Reset to factory settings	Depends on reset settings	High	Minimal
Cleaning via the web interface	Full cloud and phone cleaning	Average	Medium (30 days cart)

Remember, that Google stores deleted contacts in a special trash bin for 30 days. If privacy is your goal, be sure to empty your Trash in the Google Contacts web interface as well. Otherwise, if accidentally synchronized, the data may return.

Managing contacts on a SIM card

Despite the development of cloud technologies, many users still store numbers on a SIM card for reasons of compatibility or habit. On Redmi 10, these entries are managed through a separate settings menu.

Go to the application Contact, open the settings menu (three dots) and find the "SIM card settings" or "SIM card contacts" section. Here you will see a list of all numbers recorded directly on the operator’s chip. Select the "Delete All" option or manually select entries to erase.

It is worth noting that the SIM card has limited capacity and does not support storing additional data such as photos, email addresses or notes. Therefore, when transferring contacts from your phone to a SIM card, some information is inevitably lost.

⚠️ Attention: Deleting contacts from the SIM card is final. Unlike cloud services, the SIM card does not have a "recycle bin" function to recover deleted data.

If you do not see the delete option, your SIM card may be protected by a PIN code or does not support writing/deleting in this mode. In this case, try moving the contacts to the phone's memory through the "Copy from SIM" menu, and then delete them from the device's memory.

Using Recovery Mode

For those cases when the phone is locked, buggy, or the method through the settings is not available, there is a more radical method - using Recovery mode. This method involves completely resetting the device to factory settings (Hard Reset).

To enter recovery mode on Xiaomi Redmi 10, turn off the device completely. Then hold down the Volume Up button and the Power button at the same time. Hold them until the Mi logo appears, then release the Power button, but continue to hold the volume down until the Recovery menu appears.

Wipe Data → Wipe All Data → Confirm → Reboot

In the menu, navigation is carried out with the volume buttons, and selection is done with the Power button. Select item Wipe Data, then confirm the action. This procedure will delete absolutely all data from the phone: contacts, photos, applications and settings. The device will return to its “out of the box” state.

What to do if Recovery Mode does not start?

If the button combination does not work, try connecting the phone to the computer via a USB cable and repeat the procedure. Also make sure that the battery charge is at least 30%.

Using this method is advisable only in extreme cases, for example, before selling the phone or in case of serious software failures. To simply delete contacts, this is “shooting a cannon at sparrows,” since you will lose other important files.

Solving problems with duplicates and synchronization

After attempting to delete, users often encounter the problem of duplicates appearing or returning deleted numbers. This occurs due to a conflict between the phone's local database and the synchronization servers.

To avoid this, it is recommended to turn off the Internet (Wi-Fi and mobile data) before deleting. Perform the cleaning procedure offline. After the phone book is empty, go to the account settings and select your Google account. Click "Sync account" after making sure that the cloud is also empty.

If contacts continue to appear, they may be saved in the application cache. Go to Settings → Applications → All apps → Contacts. Select "Memory" and click "Clear cache" and "Clear all data". This will reset the phone book app itself without affecting other system data.

Also check third-party instant messengers such as WhatsApp, Telegram or Viber. They often have access to the phone book and can automatically restore numbers from their internal databases the first time they start after cleaning.

Frequently asked questions (FAQ)

Is it possible to restore contacts after deleting on Redmi 10?

Yes, if you used synchronization with Google, deleted contacts are stored in the trash on contacts.google.com for 30 days. It is also possible to restore from a previously created backup (.vcf file) or through the Mi Cloud service, if it was active.

Why do contacts appear again after deletion?

This happens due to automatic synchronization. The phone checks the local database with a cloud copy of the Google account. If there are any recordings left in the cloud, they will be automatically downloaded back when you connect to the Internet. It is necessary to clean both sources.

Will the call history be deleted along with the contacts?

No, deleting contacts from the phone book does not affect the call log (call history). To clear your call history, you need to go to the Phone application, go to the calls tab, press the menu and select “Clear call history.”

Is it safe to delete contacts through third-party applications?

Using third-party applications to clear contacts carries the risk of data leakage. It is recommended to use only the built-in MIUI tools or the official Google web interface to ensure the confidentiality of your information.

How to delete contacts if the phone does not turn on?

If the phone does not turn on, it is impossible to delete contacts locally. However, you can log into your Google account from your computer via contacts.google.com and delete numbers there. The next time you successfully turn on and synchronize the phone, the changes will be applied.
