Why don’t you remove contacts from the phone book on Xiaomi Redmi 9?

The situation when contacts on the Xiaomi Redmi 9 smartphone stop being deleted is often puzzling for users.A seemingly simple operation to clean a phone book turns into a complex quest with repeated errors and endless attempts.This is a common problem that can be caused by both software failures of the MIUI shell and synchronization conflicts with cloud services.

The reason is not always the device itself, but also the way Android processes data in the background. Sometimes the deletion process is blocked by an active application or a suspended Google sync service. Understanding the mechanics of the phone book will help you find the root of the problem faster and fix it without losing important data.

In most cases, it is sufficient to perform a number of standard procedures for cleaning the cache and verifying access rights to restore functionality, but if the problem lies deeper, such as damage to the contact database, more radical measures will be required.

Causes of errors in removal

The first thing to do is to understand why the system is blocking your actions, and most often the culprit is the app cache that has overflowed or corrupted, and when temporary files accumulate, they can conflict with current write-and-delete operations, creating a digital congestion.

Another common reason is active synchronization with a Google or Mi Cloud account. If the background is a data update process, the system can temporarily block manual deletion of records to avoid out-of-synchronization between the phone and the server.

⚠️ Note: If you are trying to remove contacts that have been imported from the SIM-These records often have limited access to edit directly in the interface.

Call aggregators or messengers (WhatsApp, Telegram, Viber) can take over the management of a phone book, and if the application is frozen, it blocks access to the contact database for other processes, including standard deletion.

Checking the source of contact storage

It is critical to determine where exactly the record you want to delete is physically stored. In today’s Xiaomi smartphones, contacts can be located in three main places: SIM-It's in your card, in your device's internal memory, or in your cloud account, and it's what you do.

If the contacts are retained on SIM-These are often displayed as "read-only" in some aggregator applications. their removal may require special import/export or use of Google's standard "Contacts" app rather than shells. MIUI. Attempting to remove them through third-party software can be blocked by the system.

If you store your phone in memory or in the cloud, the problem may be access rights. Make sure you look at the right list. Sometimes users see a combined list where contacts from different sources are mixed up, and deleting one list doesn't affect a copy in another.

To check the source, open a specific contact and look at the top of the screen or the "Change" section. There will be a storage box. If it lists a Google account, any changes will instantly be reflected on the web, which can cause conflicts when the Internet is bad.

💡

Always check where the contact is stored before trying to remove it, which will save time and prevent access errors.

Cleaning the cache and application data Contacts

The most effective way to combat software glitches is to clean up accumulated temporary files. For Redmi 9, it's a routine procedure that doesn't delete your numbers, but resets the display settings and app cache. This often shakes up the system and removes the lock.

You need to go to the system settings. Find the Apps section and select All Apps. Search the Contacts app (note that there may be more than one contact, Contacts and Phone, Google Play Services).

Inside the app menu, find the Clean or Storage button, and you'll be offered two options: Clear Cache and Clear Everything (or Reset) First, use cache cleanup. If that doesn't work, reset all the app settings, but make sure your contacts are saved to the cloud just in case.

Once you do this, the phone can run a little slower in the first few minutes, because the system needs to re-index the database. That's normal behavior. Don't be afraid if the interface gets redrawn.

Managing Google and Mi Cloud Synchronization

Synchronization conflict is a scourge of modern smartphones, and if you delete a contact on your phone while Google's server is trying to restore it from a backup, it creates a cycle, and to break this cycle, you have to temporarily turn off sync.

Go to Settings → Accounts and Sync. Select your Google account. Find Contacts and turn off the sync slider. Then try to delete the problem entries again. Now the phone will not receive commands from the top to restore.

Similar steps are worth doing for your Mi Account if you’re using the Xiaomi cloud, and it’s often dual synchronization (from two different clouds at the same time) that creates insoluble SQLite database file blocking conflicts.

⚠️ Warning: After successfully removing contacts, be sure to turn back on sync so that changes are saved in the cloud and not lost when you change your device.

Use of the web version of Google Contacts

If you can't get anything removed from your phone, the best workaround is through your browser. Google Contacts' web interface takes precedence over your mobile app and allows you to do mass cleaning without the limitations of MIUI.

Go to contacts.google.com from your computer or through your browser on your phone in full-site mode. Sign in with the same account as Redmi 9. Here you can select contact groups or individual posts and click the delete button.

Once you delete it on the web, go back to your phone's settings and force it to sync, and the phone will be told to clear the database, which is especially effective when the phone's interface is just "glutchy" and not responsive to taps.

The web version also has a Recycle Bin, where remote contacts are stored for 30 days, and if you delete the extra, you can get everything back from there, which gives you an extra layer of security when you clean the phone book in a mass manner.

💡

Use the “Combine and Correct” feature in the web version of Google Contacts. It will automatically find duplicates that often interfere with normal deletion of records.

Resetting the settings of the phone and dialer application

In the MIUI shell, calls and contacts are often handled by different but related components, and if the Contacts app is cleared and the problem persists, the system Dialer may be the culprit.

You need to find the phone component (green handset icon) in the application list, go to the phone storage and clean the data, which will reset the call history and dialing settings, but often solves the problem with the hanging deletion processes.

Also worth checking permissions. In the app menu, make sure it has access to Contacts and Phone. Sometimes, after updating the system, the rights get lost, and the application goes into read-only mode, without letting you change anything.

If that didn't work, try changing the default dialing app. Install Google Phone from Play Market and assign it to the primary. Google's interface often works more consistently than standard MIUI calling on global firmware versions.

Radical measures: Resetting and recovery

When the software is exhausted, you have to export and import, and this is the "nuclear" version of the software that allows you to recreate the contact database from scratch, and you have to export all the contacts to a.vcf file.

Save this file to your computer or to a secure cloud storage (not to your contacts sync folder, but just as a file, like a Drive) and then delete all contacts from your phone (via Google’s web interface, this is the fastest way to do it).

Once completely cleaned, import the file back. When importing, the system will rewrite all the data into the database, correcting internal indexing errors that prevented deletion, often treating even deep file system software errors.
