Why Xiaomi is not keeping contacts: reasons and solutions

You try to add a new number to your Xiaomi phone book, but after clicking Save, the contact disappears or does not appear in the list? This problem occurs on devices with MIUI versions from Redmi Note 10 to Xiaomi 13 Ultra. Most often, sync failures, crowded memory or system application errors are to blame. In this article, we will discuss 7 main reasons why you can not keep contact in the Xiaomi phone, and give step-by-step instructions for fixing each of them.

It’s important to understand that the problem can be both software (like a bug in com.android.contacts) and hardware (damaged flash memory).We’ll start with simple solutions — checking sync with Google Account and clearing the cache, and then move on to more sophisticated methods, including resetting the Contacts app settings and diagnosing memory. If you’ve tried something on this list, skip familiar steps and move on to the next sections.

1. Problems with syncing Google Account

The most common cause of contact loss is a Google Account sync that is disabled, and even if you save a number locally, the system can automatically try to sync it to the cloud, and if it fails, the contact will disappear.

1. Open Settings → Accounts and Sync → Google.
2. Select your account and make sure the switch opposite Contact is active.
3. Click on “Sync Now” and check if a contact has appeared.

If synchronization is enabled but contacts are not saved, try:

• 🔄 Delete and re-add Google Account (pre-export contacts to file) VCF).
• 📱 Update the Google Contacts app** via the Play Store.
• 🔧 Clear the cache of the Google Play Services app in Settings → Annexes → Application management.

⚠️ Note: If you have sync enabled with your Xiaomi Cloud account, turn it off temporarily – a conflict between two cloud services can lead to duplication or loss of contacts.

2. Overflowing memory or damaged flash memory

If the Xiaomi phone runs out of space, the system can block the recording of new data, including contacts.

• 📊 Go to Settings. → The phone. → Warehouse.
• 🔴 If less than 500MB is free, delete unnecessary files (cache, photos, apps).
• 🛠️ Use the built-in Cleanup Utility (Security) → Cleanup).

If the memory is not full, but the contacts are still not saved, there may be a hardware malfunction of the flash drive.

1. Install the A1 SD Bench app from the Play Store.
2. Run a write/read test – if the speed is below 10MB/s, it’s a sign of memory wear.
3. Try to keep in touch with you. SD-If it's stored there, there's a problem with the internal memory.

⚠️ Warning: If the memory test shows critical errors, do not try to reflash the phone - this may aggravate the damage to the drive.

3. failures in the Contacts or MIUI application

The com.android.contacts app (standard MIUI “Contacts”) may crash due to:

• 🗑️ Cache overflow (especially after updates).
• 🔄 Conflict with the shell MIUI (For example, after updating to MIUI 14).
• 📱 Lack of permission to access memory or contacts.

To fix this:

Stop the application in the settings|Clear the cache|Clear the data (Warning: all local contacts will be deleted!)|Reboot the phone|Check the permissions (Settings) → Annexes → Contacts → Permits)-->

If the cleaning didn’t help, try:

1. Install an alternative contact app (such as Simple Contacts or Google Contacts).
2. Turn off battery optimization for the Contacts app in Settings → Battery → Battery Optimization.
3. Check if the child mode or guest mode is on, they can block changes in contacts.

💡

If all numbers are gone after cleaning the Contacts app data, restore them from a Google backup or exported VCF file. To do this, open Settings → Google → Restore Contacts.

Conflict with duplicate contacts

MIUI can automatically combine or hide duplicates, so that new contacts are not saved (in fact, they are saved, but merged with existing ones).

1. Open the Contacts app.
2. Click on three dots in the top right corner → Contact management → Find and combine duplicates.
3. If the system offers to combine contacts, cancel this action and save the number again.

The problem may also be hidden contacts:

• 👥 Go to Settings. → Contact display.
• 🔍 Make sure all accounts are selected (Google, SIM, The device).
• 📵 Check if the filter is on by group (e.g., Favorites or Family»).

5 Mistakes SIM-card or lack thereof

On some Xiaomi models (e.g. Redmi) 9A or POCO X3) The default contacts are saved to SIM-If you put it in, you'll have to do it:

• 📶 SIM-The card can be filled (maximum) ~250 contacts).
• 🔌 Contacts to SIM Not synced with your Google or Mi Account.
• 🚫 Some operators block the recording of SIM (For example, virtual operators).

To check it out:

1. Open Contacts → Press + → See where you want to save the contact (device, SIM, account).
2. If you select SIM, try saving to Device or Google.
3. Check the SIM on another phone – if there are no contacts, the problem is in the card.

⚠️ Note: Contacts saved on SIM, They're taking up space in her memory and they can slow down the search in her phone book.

6.Blocking with antivirus or MIUI Optimizer

Built-in MIUI services, such as MIUI Optimizer or Security, can block changes to contacts if:

• 🛡️ Protection against unauthorized access (for example, if a virus is suspected).
• 🔒 Application Blocker for Contacts is enabled».
• 🔄 Memory optimization works, which suspends background processes.

How to fix it:

1. Open Settings → Applications → Application Management → Contacts → Battery.
2. Select No Limits and disable MIUI Optimization.
3. In Settings → Security → Blocker, check if the Contacts app is blocked.

If you are using a third-party antivirus (such as Avast or 360 Security), temporarily disable it and try to keep in touch again.

7. Damage to system files or firmware

If none of the previous methods worked, the problem may be corrupted system files or incorrect firmware, which often happens after:

• 🔄 Failed update MIUI (especially through Ottawa).
• 📱 Rooting or unlocking the loader.
• 🛠️ Installation of custom firmware (for example, LineageOS).

Decisions:

1. Reset the settings of the Contacts app: Settings → Apps → Contacts → Storage → Resetting settings
2. Restore your MIUI backup via Settings → About Phone → Backup.
3. Fastboot (see instructions for your model at 4PDA or Xiaomi Community).

💡

If the problem has occurred after the MIUI update, try to roll back to the previous version via Recovery. To do this, download the firmware from the official Xiaomi website and select Install update.zip in Recovery mode.
