Modern smartphones are becoming the digital storehouse of our lives, and the phone book in Xiaomi Redmi 9 is no exception. Over time, the list of subscribers grows, becoming overgrown with unnecessary numbers, duplicates or records of temporary courier services. Clearing this list is not just a matter of aesthetics, but a necessity to speed up the search for the right person and free up space in the cloud if synchronization is used.
Operating system MIUI, The Xiaomi Redmi 9 offers several ways to manage records: the user can delete numbers one by one, select groups for mass cleaning, or even use automatic tools to find duplicates. It is important to understand that the deletion process may vary depending on where the record is stored: SIM-Maps, internal phone memory or Google account.
In this guide, we will take a look at all the available methods for cleaning the phone book, learn not only to erase single records, but also to conduct a deep cleaning of the list, while avoiding the accidental loss of important information, and we will also look at the nuances of working with contacts that may “stick” to the device after changing your smartphone or resetting.
Removing single contact through a standard application
The most common scenario is to remove one particular number, and for this purpose, MIUI has an intuitive interface that is accessible directly from the call menu or from a separate application, open the Contacts app or go to the phone book tab through the Phone app.
Find the entry you want in the list. Click on the subscriber's name to open the card with the details. Here you'll see the phone number, address, email, and other details if they've been filled out. In the upper right corner of the screen or at the bottom of the menu (depending on the MIUI version), there's a three-dot button or edit icon.
Click on the three-dot menu and select Delete. The system will immediately request confirmation of the action, as it can be difficult to recover deleted records without a backup. Confirm the operation and the entry will disappear from the list forever.
⚠️ Note: If a contact is synced with Google, it will be deleted from all devices where the user logs in.
Sometimes users are faced with a situation where the delete button is inactive. This can happen if the recording is read-only, which often happens when importing contacts from some messengers or corporate Exchange accounts. In this case, try first copying the contact to the phone's memory and then deleting the original.
💡
Before a mass cleaning of a phone book, always back up through Google’s settings or export the.vcf file to a memory card.
Mass removal and cleaning of duplicates
When a phone book is full of hundreds of records, deleting them one at a time is inefficient. Xiaomi Redmi 9 has built-in batch processing tools. To take advantage of them, open the Contacts app and click on the menu icon or control button (often looks like a dot square or three horizontal lines).
Select Packet Deletion or Contact Management, and you will see a list of all the checkboxes you want to highlight, and you can manually mark dozens of numbers that need to be erased, or use the Select All feature if you plan to clean them completely.
The feature that is particularly noteworthy is the dual-app pairing function. MIUI can automatically find entries with the same names or numbers that may have been created when you re-synchronize. Go to the Settings within the contacts application and find Combine Duplicates.
- 📱 The system will analyze the database and propose a list of pairs for the merger.
- 🗑️ You can choose which data to store when combining (for example, leave both numbers in the same card).
- ✅ After confirmation, duplicates will be deleted and the information combined into one record.
This feature is especially useful after moving from an old Android smartphone, when contacts are often copied twice: once from a single device. SIM-Maps, second time from the cloud, using embedded tools MIUI This prevents manually combing thousands of lines.
☑️ Pre-deletion check
Managing Contacts through Google Account
Xiaomi Redmi 9 owners often store their data in the Google cloud for security. Deleting contact via the web interface or sync settings is a powerful tool that lets you manage your phone book remotely.This is especially handy if your phone is lost or you want to clear the list from your computer.
Go to your smartphone settings, select Accounts and Sync, then click on your Google account. Make sure it ticks the other side of Contact. Now go to contacts.google.com from any browser. This displays the full copy of your phone book.
The web interface allows you to highlight contacts using the Shift key to select range or Ctrl for selective labeling. Once highlighted, click on the basket icon. Changes will automatically affect your Redmi 9 as soon as the device connects to the Internet and syncs.
| Deleting method | Where the copy is kept | Recovery | Difficulty |
|---|---|---|---|
| Through the app | Locally and in the cloud. | From the Google cart (30 days) | Low. |
| Through Google Contacts | Only in the cloud. | Through the web interface | Medium |
| S SIM-map | On a SIM chip. | Only handcrafted creation. | Low. |
| Package removal | Depends on the source. | Hard, I need a full copy. | Tall. |
This saves you in situations where you accidentally deleted the wrong thing or a virus program has corrupted the database.
How does the shopping cart work in Google Contacts?
Working with contacts on SIM-map
Despite the development of cloud technology, many users of Xiaomi Redmi 9 still store numbers on the Internet. SIM-This can be due to a habit, the need to change devices often, or the lack of a link to a Google account.
To see contacts SIM-maps, open the Contacts app, click on the settings menu and select Display Contacts. Make sure that you have selected SIM-Now, the chip will have the entries on the chip, and they're usually in a limited format, just name and number, no photo or field.
The deletion process is similar to normal memory: select the record and press Delete. SIM-The map below, and the number of characters in the name is limited. If you plan to upgrade to a new smartphone, it is better to pre-copy these records into the internal memory of the phone.
To copy, go to Settings -> Import and export contacts. Select source"SIM-map" and the destination "Phone" or "Google account." Once successfully transferred, you can safely clear the phone. SIM-To avoid confusion in the future.
⚠️ Note: When removing contact with SIM-It's physically erased from the chip. SIM-Data cards are not possible with standard Android tools.
Some carriers may map their service numbers, and deleting them is not recommended, as this may make it difficult to access the operator's services, although in most cases they are duplicated in the system.
Solution: Contacts are not deleted or returned
Sometimes users of Xiaomi Redmi 9 face an annoying problem: a remote contact appears again after a while, most often due to the operation of synchronization mechanisms. If the record is stored in another source (for example, in a WhatsApp account, Viber or a second Google account), the system will automatically restore it when you update the data.
To solve this problem, you need to find the source of sync. Go to Settings -> Accounts and sync. Go through the list of all the services connected. If you see Skype, Facebook or corporate email, check their contact settings. Turn off sync for unnecessary sources.
Another reason is the app's caching. If the phone book isn't working properly, try clearing the cache. Go to Settings -> Apps -> Contacts -> Memory and click Clear cache. Don't confuse it with the Clear All button, otherwise you can delete the display settings.
- 🔄 Check if sync with Mi Cloud is enabled if you are using the Xiaomi ecosystem.
- 📱 Make sure that the device does not have multiple dialer apps that conflict with each other.
- 🔍 Use a number search in all messengers to find where the “resurrection” contact comes from.
In rare cases, the problem may be hidden in third-party call apps that have their own databases. Check the settings of programs like Truecaller or GetContact if they are installed on your Redmi 9.
💡
If the contact returns after deleting, the source of the problem is active synchronization with an external service or a second account.
Cleaning up the history of calls and blacklist
Often, by "deleting contact," users mean clearing a call history or blocking an unwanted subscriber, which is closely related to the phone book, but has its own nuances in MIUI. Call history is stored separately from contacts, but allows you to quickly interact with the number.
To clear the call log, open the Log tab in the Phone app, you can delete individual entries by long-pressing a number, or clear the entire log through the menu, which is useful for maintaining privacy if other people are using the phone.
If your goal is to block a contact so that it can’t reach you, simply removing it from the book won’t help. you need to add a number to the Blacklist**. On Xiaomi Redmi 9, this is done via the Security-> Blacklist app or directly from the contact card via the lock menu.
Once blacklisted, all calls and SMS from that subscriber will be blocked and you won't even see notifications.This is a more radical method than deleting, and it's effective at fighting spam and intrusive calls.
Cleaning your history and phone book regularly not only frees up space, but it also helps the system run faster, as the app doesn’t have to index thousands of old entries every time it searches.
⚠️ Note: Adding a number to a blacklist on Xiaomi can also block the number. SMS-Messages from banking services if they come from short numbers that have been accidentally blocked.
