When the Xiaomi Redmi screen does not display a name or photo of a contact during an incoming call, but only a dry digital number is visible, this problem can cause irritation for any user. This problem can occur suddenly, even if the phone previously correctly identified subscribers from your address book. Most often the failure lies not in a hardware breakdown, but in a software conflict or in the downed resolutions of the system applications of the MIUI or HyperOS shell.
Owners of Xiaomi smartphones often face the fact that after the next update of the operating system or installing a new launcher, the usual identification functions cease to work. System failure can be caused by cleaning the cache, resetting the settings or even a banal lack of RAM, because of which the background telephony process does not have time to load data from the contact database at the right time.
Before you bring the device to the service center, you should do a number of diagnostic manipulations yourself. In most cases, it takes no more than 10-15 minutes to restore correct operation and does not require special technical knowledge. We will analyze all possible causes, from simple errors in filling out the contact card to deep settings of the Android system components.
Verification of the format of number saving and synchronization
The most common, but often overlooked, reason is the wrong format for writing a phone number in the device's memory. Android may not match an incoming call with an entry in the book if the numbers are written differently. For example, one contact is saved with a +7 country code, and another comes from the operator in an international 8 format or no code at all. Make sure that all your contacts are unified.
It's also worth checking where the problem contact is stored. SIM-maps, and the phone tries to look for matches in Google account or internal memory Xiaomi, display name will not happen.
- 📱 Open the Contacts app and select a problem entry to edit.
- 🔢 Make sure the number starts with +7 (for the Russian Federation) or complied with the international standard.
- ☁️ Make sure your Google account is selected in the Save to field, not SIM-map.
- 🔄 Click the Update or Sync button in the Contact Settings menu.
⚠️ Note: If you have recently changed SIM-If you're using a card or a different smartphone, you can copy the contacts with duplicates, delete the duplicates, and leave only the ones that are linked to the cloud account.
Sometimes the problem is that the number is written with extra characters, brackets or hyphens that the system can't handle correctly when the call is incoming. Data standardization is a key step in the diagnosis. Try to remove characters ( ), and spaces, leaving only numbers and plus at the beginning.
💡
Use the “Join Contacts” feature in Xiaomi Contacts app to automatically locate and glue duplicate entries that may interfere with name definition.
Configure permissions for the application “Phone” and “Contacts”
Modern versions of MIUI and HyperOS have strict controls on applications' access to personal data, and if a system dialer has been stripped of the right to read a phone book, it will not be physically able to show the name of the caller, even if the contact is perfectly maintained, often after using memory cleaners or optimizers.
To fix this, you need to manually check access rights. Go to your device settings and find the application management section. You need to find the system application that handles calls. Depending on the firmware region, it can simply be called Phone, Google Phone, or have a Xiaomi logo.
☑️ Access rights verification
Once you log in to the permissions menu, make sure the switch opposite the Contacts item is activated. If access is denied, the system will ignore the name database. It is also worth checking the Contacts app separately, since different modules can be responsible for storing and displaying data in Xiaomi.
In some cases, resetting a specific application helps. This will not delete your numbers, but will return the program settings to factory settings, removing possible software errors. Click on the "Clear" button and select "Settings Reset" (do not confuse with "Clear all data" if you are afraid of losing local settings, although contacts are usually synchronized).
Resetting and reinstalling system components of calls
If the permission checks fail, the cache files of the Phone system application may be damaged, the accumulated debris or erroneous logs may block the correct operation of the number determination function, and cache cleaning is a secure procedure that often solves the problem of blind calls.
To do the cleaning, go to Settings → Apps → All Apps → Phone. From the menu that opens, select the data clean option. Here it is important to choose “Clear Cache”, but if this does not help, you can try “Clear All” (Warning: this will reset the settings of the call itself, for example, banning certain numbers or forwarding, but will not delete contacts).
| Action. | Impact on data | When to apply |
|---|---|---|
| Clearing the cache | Secure, data is not lost. | At the first sign of interface glitches |
| Resetting the application settings | Resets the phone's settings. | If cleaning the cache didn't help |
| Removal of updates | rolling back the app version | If the problem has occurred after the update |
| Reinstallation via GetApps | Complete replacement of application files | Critical system errors |
Another effective method is to remove system app updates, sometimes the new version of the phone contains bugs, go to the phone app card (three dots in the corner of the screen) and select "Delete updates," and the system will roll back to the factory version, after which the problem may disappear.
What to do if the cleaning buttons are inactive?
Conflicts of third-party number determiners
Many users install third-party spam detection apps, such as Truecaller, Yandex with Alice, or Kaspersky Who Calls. These programs intercept incoming calls before the system call to check the number on its database. If the application fails, you can see an empty screen or only a number.
To rule out this factor, try temporarily disabling or removing the third-party detector. If the caller's name is displayed correctly again, then the problem was in the software conflict. In the settings of the antivirus or the detector itself, there is often an option "Integration with the system" or "Map on top of other applications" that you need to double-check.
- 🛑 Temporarily remove apps like Truecaller or GetContact.
- 📞 Check if the contact name appears when you call from another phone.
- ⚙️ If the problem is solved, reconfigure the access rights for the determinant.
- 🔄 Make sure that in the battery settings, the third-party application is not prohibited from working in the background.
⚠️ Warning: Third-party determinants require broad permissions to work. If you don’t actively use their features (spam search), it’s better to rely on Xiaomi’s built-in protection, which is less in conflict with the system.
It’s also worth checking whether Do Not Disturb or Quiet Mode is enabled with special display settings. In some scenarios, MIUI may hide call details if a specific security profile or mode is activated.
Specifics of the work of Google Assistant and screensavers
In the latest versions of Android and Xiaomi shells, Google Assistant is often responsible for processing incoming calls and displaying information. If its settings are downed, the screen may not light up or show the name, which is especially true for users who have upgraded to new versions of Android 12/13/14.
You have to go to Google Assistant settings, run the assistant, or find it in your phone settings, and look for Devices or Phone and make sure that the Personal Results or Call Display option is activated, sometimes with a simple Google account reassignment.
Also, you should check the theme settings, and if you use a third-party theme from MIUI Themes, it may not display the call screen correctly. Some "curve" themes simply don't have graphic elements for the contact name, showing only the background.
Try to temporarily switch to a standard theme “Classic” or “Untitled” (standard). If the problem disappeared after the theme change, then it was a visual design. Also check the settings “lock screen” in the “Always on screen” (AOD), as there may be limitations on the display of data.
💡
Third-party themes are a common reason contact names disappear. Go back to the standard design of the system for verification.
Radical Methods: Resetting Network and System Settings
If none of the above methods worked, the system files that run the communications module may have been damaged, in which case resetting the network settings helps, which will delete stored Wi-Fi passwords and Bluetooth settings, but often restores the cellular module and contact database.
You can reset via the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Once rebooted, the phone will re-register on the operator’s network and the contact database must be loaded correctly. This is a secure method that does not affect personal files.
In extreme cases, if the problem is massive and manifests itself with all contacts, a complete reset of the device may be required.
Should I check the phone?
⚠️ Before you reset completely, make sure you remember the password from the Google account and Mi Account linked to the device.Otherwise, the phone may lock after the reboot.
Sometimes the problem is solved by waiting, and after a major firmware update, the system indexes files and contacts in the background, during which time the phone can run slowly, and finding contacts can take time, and give the device a couple of hours of work with the screen on and charging.
