You pick up the phone, and on the screen instead of a contact name there is only a bare number? Or, instead of the usual “Mom” or “Boss”, the mysterious “Unknown” is displayed? The problem with caller data not being displayed on smartphones ASUS occurs more often than it seems. And if on Samsung or Xiaomi this is usually cured by rebooting, then owners of devices from the Taiwanese brand have to dig deeper.

In this article we will analyze all possible reasonswhy your ZenFone or ROG Phone stopped showing subscriber names - from trivial cache failures to hidden operator settings. And most importantly: we will give step-by-step guide with pictures (where necessary), which will return the number identification function without resetting to factory settings. Spoiler: in 80% of cases the problem is solved in 5 minutes.

But first, an honest answer to the main question: Is the smartphone itself to blame for this? Only in 30% of cases. More often than not, SIM card settings, conflicting applications, or even the actions of your mobile operator are to blame. Therefore, do not rush to take your phone to a service center - most likely, you can handle it yourself.

1. Checking the basic settings: what could have gone wrong?

Start with the obvious - sometimes the problem lies in accidentally changed parameters. On smartphones ASUS (especially on models ZenFone 8/9 and ROG Phone 5/6) there are several “delicate” places where the number recognition setting may get lost after updates.

The first thing you need to do:

  • 📱 Open application Phone → click on the three dots in the upper right corner → Settings → Additional settings.
  • 🔍 Check the item Caller ID (or Caller Identification on some firmware). It should be enabled.
  • 📡 Make sure that in the section SIM cards and mobile networks for your SIM the option is enabled Transfer of caller ID.

If these parameters are already activated, but the problem remains, proceed to the next step. On some firmware ASUS (for example, on ZenUI 8) the number identification option may "freeze" in an intermediate state - turn it on, exit the settings, and then go back in and check.

2. Application conflict: who is stopping you from identifying numbers?

One ​​of the most common reasons is third-party applicationsthat intercept calls or block access to the phone book. Most often the culprits are:

  • 🛡️ Antiviruses (Avast, Kaspersky, 360 Security) - they can block access to contacts “for security.”
  • 📞 Alternative callers (Truecaller, GetContact, Drupe) - sometimes conflict with the standard application Phone.
  • 🔒 Applications for blocking spam (Hiya, Should I Answer?) - can “jam” number identification for all incoming calls.

How to check:

  1. Go to Settings → Applications → Permissions.
  2. Find the section Contact or Phone and see which applications have access.
  3. Disable permissions for suspicious apps (or remove them temporarily).
  4. Restart your phone and check if the caller's name appears.

Open Settings → Applications → Permissions

Find the "Contacts" or "Phone" section

Disable access for antiviruses and dialers

Delete Truecaller/Hiya (if installed)

Restart smartphone -->

If after removing third-party dialers the problem disappears, it means that the application is to blame. In this case, you can try:

  • Update it to the latest version.
  • Reset the application settings in Settings → Applications → [name] → Storage → Reset.
  • Write to support developer with a description of the problem (indicate the model ASUS and version of Android).
⚠️ Attention: On some firmware ASUS (especially on Android 12+) the standard application Phone may conflict with Google Phoneif it is set as system. In this case, you will have to select one of them in the default settings.

3. Problems with the SIM card and operator: why are they to blame?

If the settings are correct and there are no conflicting applications, the culprit may be mobile operator. The fact is that identifying the caller's name works through the service CLIP (Calling Line Identification Presentation), and sometimes operators limit its operation. This happens especially often:

  • 🆔 When connecting new tariffs (for example, “unlimited” with restrictions).
  • 🔄 After changing the SIM card (for example, when switching from physical to eSIM).
  • 🌍 When roaming or using virtual operators (for example, Tele2 on the network Rostelecom).

How to check:

  1. Call from another phone to your number. If your name is displayed on the screen, the problem is not operator.
  2. Insert the SIM card into another phone (for example, iPhone or Samsung). If the names are not displayed there, the operator is to blame.
  3. Call the support of your mobile operator and ask. Is the "Caller ID" service active (sometimes it is disabled by default).
Operator Command for checking CLIP Support phone
MTS *111*0887# 0890
Beeline *110*181# 0611
MegaFon *105*09# 0500
Tele2 *155*1# 611

If the operator confirms that everything is in order on his part, but the problem remains, proceed to the next section.

4. Cache and data failures: how to do it. clean the system without resetting?

A common cause of the problem is damaged cache applications Phone or Contact. On smartphones ASUS this happens after:

  • 🔄 Firmware updates (especially when upgrading to a new version Android).
  • 📥 Installing major updates via FOTA (for example, from Android 11 to Android 12).
  • 🗑️ Incorrect deletion of contacts or import/export of the phone book.

How to clean cache:

  1. Go to Settings → Applications → Manage applications.
  2. Find applications Phone i Contact (sometimes they are called Contacts Storage).
  3. For each of them, click Storage → Clear cache.
  4. If that doesn’t help, click Clear data (this will delete the call history, but the contacts will remain).
  5. Reboot your phone.
💡

If your contacts are missing after clearing the data, don’t panic! They are synchronized with your Google account automatically. Check if synchronization is enabled in Settings → Accounts → Google → Synchronization. contacts.

If clearing the cache did not help, try reset network settings:

  1. Go to Settings → System → Reset settings.
  2. Select Resetting Wi-Fi, mobile network and Bluetooth settings.
  3. Confirm the action and restart the device.
⚠️ Attention: On some models ASUS (for example ROG Phone 3), resetting network settings may lead to the loss of saved access points Wi-Fi. Write down your passwords in advance or make a backup via Settings → Google → Backup.

5. Firmware and kernel update: when only a hard reset helps

If all the previous methods did not work, the problem may lie in outdated firmware or a malfunction of the modem core of the Smartphone. ASUS are known for sometimes losing functionality after automatic updates (especially if the update is interrupted).

What to do:

  1. Check that the firmware is up to date:
    • Go in Settings → System → Software update.
    • If there are updates available, install them.
  2. Install the firmware manually (if automatic updating does not help):
    • Download the latest firmware version for your model from the official site ASUS.
    • Copy the file .zip to the root folder of the phone.
    • Go to Settings → System → Software update → Three dots → Select firmware file.
  • Reset to factory settings (last chance):
    • Back up your data via Settings → Google → Backup.
    • Go to Settings → System → Reset settings → Delete all data.
    What to do if after the reset the problem remains?

    If even after a complete reset the names of callers are not displayed, this may indicate a hardware problem with the modem or SIM card. In this case:

    1. Check the SIM card on another device.

    2. If the problem persists, contact your operator for a SIM replacement.

    3. If the SIM works fine, take the phone to a service center ASUS to diagnose the modem chip.

    On models ASUS ROG Phone i ZenFone 7/8 sometimes it helps flashing via ADB Sideload. To do this:

    adb sideload [firmware_filename].zip

    But this method requires an unlocked bootloader and is only suitable for experienced users.

    6. Alternative solutions: if all else fails

    If all standard methods have been exhausted, but the problem remains, try non-obvious methods:

    • 🔄 Change SIM card slots. On some models ASUS (for example, ZenFone 6), the second slot may not work correctly.
    • 📶 Turn on airplane mode for 30 seconds, then turn it off. This resets the connection to the operator's network.
    • 🔧 Disable VoLTE/VoWiFi. Sometimes these functions conflict with number identification. Find them in Settings → SIM cards and mobile networks → [your SIM] → Calls.
    • 📱 Install an alternative dialer. For example Google Phone or Simple Dialer —they can bypass system restrictions.

    If you use dual SIM cardstry:

    1. Leave only one SIM (the one to which calls without a name are received).
    2. Reboot the phone.
    3. Check whether the number identification appears.
    4. If yes, the problem is a conflict between SIM cards. Solution: disable the Caller Identification service for the second SIM in the operator settings.
    💡

    On smartphones ASUS with two SIM cards, the Caller ID function can only work for one of them. This is a firmware limitation and cannot be bypassed without root access.

    7. Hardware problems: when is the hardware to blame?

    In rare cases, the problem lies in physical malfunction:

    • 📶 Damaged SIM contact. If the SIM card contacts are dirty or bent, the phone may not correctly read operator data.
    • 📡 Faulty modem. On ASUS ZenFone i ROG Phone a separate chip is responsible for processing calls. If it is damaged, number identification will not work.
    • 🔋 Power problems. If the battery is weak, the phone can “save” and turn off background services, including number identification.

    How diagnose:

    1. Check the SIM card on another phone. If everything works there, the problem is yours ASUS.
    2. See if the phone in the SIM card area gets warm during a call (this may indicate a short circuit).
    3. Try calling from another number - if the sound is intermittent or disappears, the modem is to blame.

    Solutions:

    • Clean the contacts of the SIM card with alcohol (carefully, without pressing).
    • If the phone is under warranty, contact a service center ASUS.
    • If there is no warranty, check the cost of repairing the modem chip (this may be expensive). ROG Phone it can be expensive).
    ⚠️ Attention: On some models ASUS (for example, ZenFone 5Z), problems with number identification may appear after the phone has been dropped. Even if there is no external damage, the cable of the antenna or modem module could come off.

    FAQ: Frequently asked questions about the problem

    Why did my ASUS ROG Phone 5 names stop displaying only for some contacts?

    This is a typical problem with sync conflict. Your contacts may be duplicated (for example, the same number is saved in the phone book, and in Google Contacts, and in Viber). The phone doesn't know what name to show and displays the number. Solution:

    1. Open Contacts → Settings → Merge duplicates.
    2. Delete unnecessary copies numbers.
    3. Turn off contact synchronization for unnecessary accounts (for example, VK or Facebook).
    I updated Android 12 to Android 13 to ZenFone 9, and the names of the callers disappeared. How to return?

    This is a known problem with firmware ASUS when upgrading to new versions Android. Helps:

    1. Resetting application settings Phone (in Settings → Applications → Phone → Storage → Reset).
    2. Install Google Phone from Play Market and assigning it as the default dialer.
    3. Roll back to the previous version of the firmware (if the reset did not help).

    If it does not help, wait for the patch from ASUS (usually released within 1-2 months after a major update).

    The screen displays “Unknown”, although the number is in the contacts. business?

    This happens if:

    • The number is saved in incorrect format (for example, with spaces or without a country code).
    • The contact is saved in SIM card, and not in the phone memory (on ASUS the definition works only for contacts in the phone/Google).
    • The function is enabled "Hide contacts without numbers" in the contact settings.

    Solution: edit the contact, making sure that the number is saved in the format +79XXXXXXXX (with country code).

    After installation Truecaller names stopped displaying How. fix?

    Truecaller conflicts with the standard dialer ASUS due to call interception. To return names:

    1. Open Truecaller → Settings → Call detection.
    2. Disable the option Show Truecaller names instead of contacts.
    3. In Android settings (Settings → Applications → Truecaller → Permissions) disable access to Contacts.
    4. Reboot your phone.

    If that doesn't help, delete Truecaller completely and clear the cache dialers.

    Is it possible to return number identification without resetting the settings?

    Yes, in 90% of cases less radical methods help:

    1. Clearing the dialer and contacts cache (see section 4).
    2. Removing conflicting applications (see section 2).
    3. Manually setting up an APN (access point) for your operator.
    4. Updating firmware via Settings → System → Software update.

    A reset to factory settings is only needed if the problem is hardware or caused by a serious firmware failure.
