When Xiaomi doesn’t keep contacts, it often takes users by surprise, when a number is just entered disappears immediately after the app is closed or doesn’t appear in the call list, which is a critical mistake, as losing numbers can lead to serious communication problems at the most inopportune time.
The reasons for this behavior of a Redmi or Poco smartphone can be found in software failures of the MIUI shell, as well as incorrect synchronization settings for Google accounts. Often the system simply does not understand where exactly it needs to write new data from the address book.
In this article, we will discuss in detail all possible scenarios for a system to refuse to write numbers, you will learn how to forcefully change the default save location and why cloud synchronization sometimes blocks local records.
Default location verification
The most common reason Xiaomi doesn't keep contacts is because of the choice of storage. SIM-A card that has a limited volume and an outdated storage format, unlike cloud accounts, a SIM cannot store additional fields like an email or an address.
To fix this, you need to open the Contacts app and go to settings, and you need to find Settings and select Import and Export Contacts, and that's where the parameter that tells the system your preferred storage is often hidden.
It is recommended to always choose a Google account or Phone as your primary storage location, which will provide automatic backup and make it easy to move the number base when you change device.
⚠️ Note: When choosing storage for SIM-Some fields (e.g., second number or photo) can be cropped or completely deleted by the system without the possibility of recovery.
💡
Always use a Google cloud account to store your contacts, which ensures that they are safe even if you completely flash or lose your smartphone.
If you have chosen the right account but the problem persists, try switching to a different profile or creating a new one. Sometimes a particular account may have sync limitations.
Problems with application permissions
The MIUI shell and the new HyperOS are known for their aggressive security policies, the system can turn off permissions for system applications if it considers their actions suspicious, and if the Contacts or Phone application does not have permission to write to memory, new numbers will simply not be added.
To check, go to Settings → Apps → All apps. Find Contacts and Phone from the list. Inside the menu of each application, you need to open the Permissions section.
Make sure Contacts, Memory, and SMS are activated. Without memory access, the application cannot physically create a new entry in the device’s database.
- 📱 Open the settings of a particular application through the Task Manager.
- 🔒 Check if the switch is in the position "Forbidden».
- ✅ Include all necessary rights of access to personal data.
After changing the settings, it is recommended to completely restart the smartphone, which will allow the Android system to re-initialize services and apply updated security policies.
☑️ Access rights verification
Clearing cache and contact data
Accumulation of temporary files or damage to the database can cause Xiaomi to stop saving new records, often after a failed system update or failure to sync with the cloud, in which case you need to clean the cache.
Go to the application management menu, find Contacts, and select Memory. Click Clear Cache. This is a safe action that won't delete your saved numbers, it will only remove temporary files.
If cleaning the cache didn't work, you can try a more radical method, "Clean everything" or "Reset" that will only delete the app's local settings, but if sync is disabled, there is a risk of losing numbers stored only in the phone's memory. Before you do that, make sure your contacts are copied to your Google account.
| Action. | Impact on data | Recommendation |
|---|---|---|
| Clearing the cache | Secure, data is not lost. | Recommended for any failures |
| Clearing of data (Discharge) | Resetting the application settings | Only after checking the synchronization |
| Removal of updates | Return to the factory version | If the problem has occurred after the update |
Once the data is reset, the Contacts app will return to the post-purchase state, and you will have to reconfigure the contacts and filters you display.
Google Synchronization Conflicts
Often the problem is not with the phone itself, but with Google servers, so if the account is overcrowded or there is an authorization error, the system blocks the recording of new contacts to avoid losing existing ones, and the sync status can be checked in the account menu.
Go to Settings → Accounts and Sync. Select your Google account and make sure the slider opposite Contacts is active. If you see an error or warning icon, try deleting your account and adding it again.
Sometimes manual sync activation helps, click three dots in the corner of your account screen and select Sync. If the process freezes, it will indicate network or server problems.
What to do if your account is not deleted?
It's important to understand that when you sync it, removing the contact on your phone will automatically remove it from the cloud, and be very careful when cleaning duplicates.
Third-party annexes and duplicates
Installing third-party dialers or contact managers from Truecaller, GetContact, and similar services often causes conflicts, and these applications try to intercept database management, leading to write errors, and Xiaomi can block or prioritize them.
Try temporarily removing all third-party applications associated with telephony. After deleting, restart the device and check the standard call. If the problem disappears, then the conflict was caused by third-party software.
It is also worth checking for duplicates. The system may refuse to save a new number if it sees an identical entry in a different format (for example, with and without a country code).
- 🗑️ Remove number-defining applications.
- 🔄 Reset the settings of the standard application "Phone».
- 🔍 Check the list for duplicate records.
Some antiviruses can also block entry to system registers. Check your security software settings for restrictions on system applications.
Failures after system update
After updating MIUI or switching to HyperOS, bugs can occur that affect the basic functions, and developers sometimes make errors in new firmware versions that affect the stability of the SQLite database where contacts are stored.
If the problem appears immediately after the update, wait for the security patch to release. However, you can try to clean the Dalvik Cache partition through Recovery mode (you need an unlocked bootloader and custom recapvery, or a standard cleanup through the recovery menu).
In standard recovery mode, choose Wipe Data (caution, it’s a full reset!) or just Wipe Cache if it’s available in your version. It’s safer for regular users to wait for the Contacts app update via Google Play.
⚠️ Warning: Do not try to reset your phone to factory settings unless you have a backup of contacts.You risk losing the entire phone book irretrievably.
💡
Failures after an update are most often solved by waiting for a patch from developers or reinstalling updates to system applications through settings.
In rare cases, a rollback to the previous firmware version helps, but it is a complex procedure that requires a PC and special tools from Xiaomi.
