How to Remove Contact with Xiaomi Redmi 9: Full Guide

Xiaomi’s Redmi series smartphones, including the popular Redmi 9, feature a MIUI shell that has its own system-application specificity. Unlike pure Android, contact management can be done through different interfaces, sometimes confusing users, often requiring the phone book to be cleaned of old records or uninstalled intrusive numbers.

The deletion process can vary depending on where the number is stored: SIM-It's a map, a device's internal memory, or a Google account, and understanding this difference is critical to keeping important data intact, or to clearing up your device before selling.

We will look at both the standard ways to use the built-in app and the duplicates that often appear after changing the phone, and we will also focus on removing hidden and blocked numbers that are not always visible in the general list.

Basic removal of one contact through the application

The easiest way to get rid of an unnecessary number is to use the standard Contacts or Phone app preinstalled in MIUI. The interface may vary slightly depending on the firmware version, but the logic of the action remains the same. Open a list of all your records and find the desired number.

Once you have found the recording, click on it to open the full subscriber card, which displays all the associated numbers, email addresses and other information, and in the upper right corner or bottom of the screen (depending on the theme of the registration), there is a control menu.

• 📱 Click on the three-dot icon or gear to call the action menu.
• 🗑️ Select “Delete” in the drop-down list of options.
• ✅ Confirm the action in the pop-up window so that the record disappears forever.

Please note that when you delete, the system may request confirmation, warning you that it is impossible to restore data by standard means. If you delete a contact by mistake, immediately check the shopping cart in the Google Contacts app if synchronization was enabled. In some versions of MIUI, deleted records can be temporarily stored in a special section “Recently deleted”.

⚠️ Note: If you see a message that the contact is “read-only”, it means that it is saved on the phone. SIM-A card or corporate account that requires special editing rights, in which case standard deletion will not work without first copying.

If your goal was to stop calls, you'll need a lock function, not an address book deletion. For mass clearing, this method is too slow, so it's better to use group highlighting.

Mass removal and work with duplicates

Xiaomi Redmi 9 owners often face the problem of duplicate records, especially after moving from an old device or recovering from a backup.The system can save the same number several times if it was written in different formats (for example, with and without country code).

The Contacts app has a powerful list management tool built into the MIUI shell. Go to the app settings (usually through the More menu or three dots), find the Contacts Organising or Contact Management section.

If automatic pairing doesn't work, you can delete a group of numbers right away, and then in the main contact list, press and hold your finger on one of the records until the tick appears, and then the selection mode will be active.

• 👆 Swipe your finger through the list or tick the necessary contacts.
• 🗑️ Click the “Delete” button (basket icon) at the bottom of the screen.
• 📂 The system will prompt you to select a deletion source if your contacts are scattered across different accounts.

When you delete a large number, be especially careful. Accidentally allocated important numbers will be difficult to recover if the sync with the cloud has been disabled. Always check the dedicated list before final confirmation of the operation. This is especially true for those who only store contacts in the device memory, not in the cloud.

Removal of contacts with SIM-map

Many users still keep numbers on the SIM-But on modern smartphones like the Redmi 9, it's more reliable. SIM-Direct deletion of the records from the chip through the standard contact menu is often impossible — the system only copies them to the memory of the phone for display.

To remove the number that is physically located on SIM-You can copy it to your internal memory or Google account, and then you can delete it from the SIM card through a special manager. → Annexes → Contact or use the built-in “Contact” app».

From the contact management menu, select the option “Import/Export contacts”. You will need the option “Copy with the contact”. SIM-Once all the numbers are in your phone’s memory, you can delete the source.

Some carriers or old ones SIM-cards may have restrictions on the number of characters in a name or the number of entries. When transferring to a Xiaomi phone, long names may be cropped. After removal from the SIM card, it is recommended to restart the device so that the list is updated correctly.

⚠️ Attention: SIM-Maps have limited storage and often don’t support saving multiple numbers for a single contact or adding photos. Google’s cloud storage is devoid of these drawbacks.

Working with blacklist and hidden numbers

Often users want to delete a contact so it stops calling, but confuse deletion from the phone book with locking. MIUI has a powerful built-in antivirus and security module that manages a blacklist. If the number is locked, removing it from contacts will not unlock calls.

To manage blocked subscribers, open the Security app (green zipper icon) go to Antispam or Blacklist, and you will see all the numbers that are not allowed to enter. To delete the number from this list, click on it and select Delete or Unblock.

There's also a Hidden Contacts feature that allows you to hide certain records from prying eyes, and they don't show up in the public list until you have a special code or password in place, to remove that contact:

1. Open the Contacts app.
2. Enter the #number# code in the dialing field (where “number” is your previously specified concealment password).
3. A hidden list will appear from where you can delete the record in the standard way.

If you forget your hidden contacts password, you can't restore them or delete them without resetting the app or the entire phone. Be careful when setting privacy passwords. Redmi 9 also allows you to use the Second Profile space, where the contacts are completely isolated from the main one.

Sync and delete via Google Contacts

The most reliable way to manage contacts on Xiaomi Redmi 9 is through Google’s web interface, which allows you not only to delete numbers, but also to restore deleted ones accidentally, since Google stores a history of changes for 30 days, which is the only way to guarantee that contacts are restored after resetting your phone settings.

Go to contacts.google.com from your computer or smartphone browser. Sign in with the same account you use on your phone. You'll see a full copy of your phone book. Any change here will instantly affect your device.

To restore remote contacts on Google, click on the gear icon (Settings) and select “Cancel Changes.” You can roll back the database state 10 minutes, an hour, or even 30 days. This saves you in situations where a viral app or mis-sync has cleared the entire book.

Cache cleanup and application reset Contacts

Sometimes the problem with deleting contacts is software-based: the Contacts app freezes, doesn't save changes, or displays already deleted records, in which case cleaning the cache and system application data helps, and this won't delete your numbers (if they're synchronized), but will reset the display settings.

Go to Settings → Apps → All apps. Find Contacts and Phone in the list. Click on each and select Clear → Clear Cache. If the problem is not solved, you can click Clear Everything (or Reset), but make sure that sync with Google is active.

• 🔄 This action will restart the telephony service.
• 📂 The interface of the list of numbers will return to the factory appearance.
• ⚙️ Sorting and display settings will reset.

After resetting, the phone can reload contacts from the cloud for a period of time (5 to 15 minutes), during which time the list may be empty — this is normal behavior of the Android system based on MIUI.

💡

Use Google Contacts instead of the standard MIUI app, which has a more user-friendly interface, works better with duplicates and ensures that your account data is safe.
