When Xiaomi displays only a phone number instead of a saved contact name on the screen during an incoming call, it can make life very difficult. You don't know who is trying to contact, and you have to guess, pick up the phone or ignore the call. This problem is common among users of MIUI and HyperOS shells, and often lies not in hardware malfunctions, but in software conflicts or synchronization settings.
Most often, the root of the evil lies in the operation of the Contacts app or in how the system handles duplicate records. Redmi and POCO smartphones can confuse between the local database and cloud storage if the synchronization went wrong, sometimes the culprit is the operator who transmits information in the wrong format, or third-party number detectors that intercept call management.
In this article, we will discuss in detail all possible reasons for the absence of subscriber names when an incoming call is made, you will learn how to properly clear the cache of system applications, check permissions and configure the display of contacts so that your smartphone again shows full data about the caller.
Checking the settings of the display of contacts in MIUI
The first thing to do is make sure that the configuration of the Contacts app itself is not limited to display. The system can hide certain groups or sources, which prevents the name from being pulled from the database when calling. Go to the Contacts app, click three dots in the corner and select Settings, and then Display Contacts. Make sure that the tick is opposite All Contacts.
Often, the problem is solved by a forced list update. In the same settings menu, find Update Contacts or Sync Now. If you have a Google or Mi Account connected, the system will try to verify the data with the server, especially if you have recently changed your phone or restored a backup.
⚠️ Warning: If the contact list is empty after updating, check the Internet connection. Sync will not pass without access to the network, and the phone will show only those numbers that are physically stored on the Internet. SIM-name-card.
It's also worth checking if Phone Only or SIM Only is enabled. Some versions of MIUI may have a filter that hides contacts from the cloud by default, switch to All Sources to cover as many records as possible, and then restart the device and check the result.
💡
Export contacts to.vcf. This will save your phone book if the sync with the cloud fails and the data is lost.
Conflicts with number-defining applications
One of the most common reasons why you can't tell who's calling is because of the conflict between the system typer and third-party applications like Truecaller, GetContact or Yandex.Determinator, which try to intercept the incoming call to show their namebase, but often do so incorrectly or block access to the local phone book.
If you use these apps, try temporarily disabling or uninstalling them. Go to Settings → Apps → All apps, find a determinant and select Delete or Disable. Then check if the caller's name appears on the test call, and if the problem disappears, it means that there was a conflict of access rights.
In some cases, complete deletion is not required, just reconfigure the rights. Go to the settings of the determining application, find the "Definition" section and turn off the display of names for contacts that are already in your book. Let the system use its data for familiar numbers, and third-party software connects only for unknowns.
There is another caveat: Spam blocking apps can label contacts as “Spam” or “Unknown” by overlapping the real name. Check the blacklist and lock settings in the Security → Antispam section. Make sure your contacts are not mistakenly there.
Cleaning cache and system application data
The accumulation of temporary files and errors in the work of system services is a classic problem of Android: if the cache of the Phone or Contacts application is damaged, the device stops correctly matching the incoming call number with the record in the database, and you can solve this by completely cleaning the data.
Follow the following steps:
- 📱 Open Settings and go to the Application section.
- 🔍 Find the Contacts app in the list (sometimes there may be several, for example, Contacts). SIM» and “Google contacts»).
- 🗑️ Click Storage and select Clear Cache and then Clear Everything (or Reset Settings) Don't be afraid, the numbers themselves won't be deleted if they're synced with your account.
- 📞 Repeat the procedure for the phone application (Number dialing).
Once cleaned, the system can think for a while, restoring the indexes. Give the smartphone 5-10 minutes at rest, without turning off the screen, so that the processes are completed. Then reboot the device. This action often helps when the bell interface is buggy.
☑️ Checklist for data cleanup
Problems with Google account and synchronization
Modern Android smartphones heavily rely on Google’s contact storage account. If sync is disabled or error-prone, the phone can see the number but not know what name it corresponds to, since the database is stored in the cloud, not in the device’s memory.
Check the synchronization status:
- Go to Settings → Accounts and Synchronization.
- Select your Google account.
- Make sure the switch opposite the Contact point is active (blind).
- If it is already on, turn it off, wait 10 seconds and turn it on again to start forced synchronization.
What to do if the contacts are duplicated?
It's also worth checking which account is the default to save new numbers. If you save a number to your local phone storage, and the system only searches Google when you call, you won't see the name. In the contact settings, set the display priority for the desired account.
Comparison of Name Recovery Methods
Different methods of solving a problem have different effectiveness depending on the cause of the failure. Below is a table that will help you choose the right way to solve the problem if you failed to fix the situation the first time.
| Method of decision | Efficiency | Difficulty | Risk of data loss |
|---|---|---|---|
| Update of contact list | Low. | Minimum | No. |
| Removal of number-determiner | Tall. | Low. | No. |
| Cleaning up the app cache | Medium | Medium | No. |
| Resetting network and application settings | Tall. | Tall. | Minimum |
As you can see from the table, the safest first step is to update the list. If it doesn't work, you should pay attention to third-party software. Radical measures, such as resetting, should only be used as a last resort.
⚠️ Before performing any actions related to cleaning app data or resetting settings, make sure your contacts are saved to the Google cloud or exported to a file.
Additional settings and hidden functions
There are hidden settings in the MIUI shell that can affect call performance, such as Smart Dial or Xiaomi integration sometimes conflicts with basic Android functionality. Try disabling all additional features in the Phone app settings.
Also check the format of the numbers. If your notebook has an international number (e.g., +7...) and the operator transmits it in city (8... or no code), the system may not recognize the match. Try editing a couple of important contacts by changing the format of the number, and see if the name appears.
💡
Most often, the problem is solved either by removing the third-party determinant or simply resynchronizing your Google account.
If nothing works, you can try resetting your network settings. It won't delete your personal files, but it will return all network settings (Wi-Fi, Bluetooth, Mobile Network) to factory values. → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.
